Impact of SPS heating on VLF, LF, and MF telecommunications systems ascertained by experimental means  

DOE Green Energy (OSTI)

The results of experiments undertaken to assess the potential impact of the operation of the Satellite Power System on the D and E regions of the ionosphere, and on telecommunication systems that are dependent upon the structure of the lower ionosphere are summarized. Using the high-power high-frequency transmitter facility located at Platteville, Colorado, power densities comparable to the Satellite Power System can be delivered to the heights of 70 to 100 km above the surface of the earth. Observations of the performance of telecommunication systems that operate in the VLF, LF, and MF portions of the spectrum have been investigated during times when the ionosphere was modified with SPS comparable power density and when it was not. The results obtained indicte that the SPS, as currently configured with a peak power density of 23 mW/cm/sup 2/, will not adversely impact upon the performance of VLF, LF, and MF telecommunication systems.

Wang OIS glossary package for reformatting documents telecommunicated to the OIS system  

SciTech Connect

Documents that are composed on a computer and then transmitted by telecommunications into a Wang Office Information System (OIS) word processing system need to be reformatted and cleaned up before they can be used properly as word processing documents suitable for further revisions or additions. This report describes a group of glossary entries created for the Wang OIS which simplifies the job of cleaning up telecommunicated documents. This glossary is a semi-automated process designed to eliminate most of the tedious work needed to be performed in removing extra spaces and returns, adjusting formats, moving material, repagination, using tabs or indents, and similar problems. The report briefly discusses the problems, describes the glossary approach to solving them, and gives instructions for actually using the glossary entries.

Global Energy Management System  

E-Print Network (OSTI)

Exxon Mobil Corporation has undertaken voluntary actions to continuously improve energy efficiency in our operations for many years. From 1973 to 1999, we improved the energy efficiency of our refineries and chemical plants by over 35 percent - saving the cumulative equivalent of 1.8 billion barrels of oil and reducing carbon dioxide emissions by over 200 million tonnes. In 2000, we redoubled our efforts with deployment of our Global Energy Management System (GEMS), which utilizes international best practices and benchmarking to identify energy efficiencies at each of our refineries and chemical plants. Thus far, we have identified opportunities to improve the energy efficiency of these facilities by an additional 15 to 20 percent. At full implementation, savings are expected to total $500 million to $1 billion per year, with an associated reduction in carbon dioxide emissions of about 10 million tonnes per year - roughly equivalent to removing 1.5 million cars from the world's roads.

Method and system for conserving power in a telecommunications network during emergency situations  

Science Conference Proceedings (OSTI)

Disclosed is a method and apparatus for conserving power in a telecommunications network during emergency situations. A permissible number list of emergency and/or priority numbers is stored in the telecommunications network. In the event of an emergency or power failure, input digits of a call to the telecommunications network are compared to the permissible number list. The call is processed in the telecommunications network and routed to its destination if the input digits match an entry in the permissible number list. The call is dropped without any further processing if the input digits do not match an entry in the permissible number list. Thus, power can be conserved in emergency situations by only allowing emergency and/or priority calls.

Surety of the nation`s critical infrastructures: The challenge restructuring poses to the telecommunications sector  

Science Conference Proceedings (OSTI)

The telecommunications sector plays a pivotal role in the system of increasingly connected and interdependent networks that make up national infrastructure. An assessment of the probable structure and function of the bit-moving industry in the twenty-first century must include issues associated with the surety of telecommunications. The term surety, as used here, means confidence in the acceptable behavior of a system in both intended and unintended circumstances. This paper outlines various engineering approaches to surety in systems, generally, and in the telecommunications infrastructure, specifically. It uses the experience and expectations of the telecommunications system of the US as an example of the global challenges. The paper examines the principal factors underlying the change to more distributed systems in this sector, assesses surety issues associated with these changes, and suggests several possible strategies for mitigation. It also studies the ramifications of what could happen if this sector became a target for those seeking to compromise a nation`s security and economic well being. Experts in this area generally agree that the U. S. telecommunications sector will eventually respond in a way that meets market demands for surety. Questions remain open, however, about confidence in the telecommunications sector and the nation`s infrastructure during unintended circumstances--such as those posed by information warfare or by cascading software failures. Resolution of these questions is complicated by the lack of clear accountability of the private and the public sectors for the surety of telecommunications.

FY 1997 Hanford telecommunication and informations system user profile, milestone IRM-097-003  

SciTech Connect

This document reports survey data collected from the U.S. Department of Energy, Richland Operations Office (DOE-RL), Project Hanford Management Contract (PHMC) companies, and the PHMC enterprise companies for purposes of characterizing the Hanford Local Area Network (HLAN) user profile. Telephone, radio, and pager data are also provided. The data reveal that job tasks of the 8,500 Hanford Site workers who use the HLAN are highly, if not completely, computer dependent. Employees use their computers as their pens and paper, calculators, drafting tables and communication devices. Fifty eight percent of the survey respondents predict 90 to 100% loss in productivity if they had no access to a computer. Additionally, 30% of the users felt they would have a 50 to 80% loss in productivity without computers; and more than 68 % use their computers between 4 and 8 hours per day. The profile also shows th at the software packages used most heavily are cc:Mail` the Windows version, Hanford Information, WordPerfece, Site Forms and Look-up. Use of Windows-based products is very high. Regarding the productivity tools that are seldom used, 49 % of the respondents say they ``never use`` the Hanford Help and Hints (HUH). The use of the external intemet by Hanford has shown a large increase. The survey indicates that users rate the intranet and the ability to access other sources of information as the fourth most important computer application. The Microsoft System Management Server (SMS 4) data show that more than 60% of the computers on the HLAN need replacement or upgrades to run the Windows 95 Operating System, which has been selected as the PHMC standard. Although data also show that 77% of the PHMC machines are running the current standard Windows for Workgroup version 3. 1 1, they do not have the memory and/or the hard disk space to upgrade to Windows 95. The survey results indicate that telephone system use is also high and regarded as a useful tool. Pager use is very high and has continued to rise even as the numbers of employees dropped. The number of radios is decreasing as the employee numbers drop.

Home Home Global Home Filesystem Overview Global home directories (or "global homes") provide a convenient means for a user to have access to source files, input files, configuration files, etc., regardless of the platform the user is logged in to. Wherever possible, you should refer to your home directory using the environment variable $HOME. The absolute path to your home directory (e.g., /u4/elvis/) may change, but the value of $HOME will always be correct. For security reasons, you should never allow "world write" access to your $HOME directory or your $HOME/.ssh directory. NERSC scans for such security weakness, and, if detected, will change the permissions on your directories. Platforms Utilizing Global Home The Global Home file system is available on all NERSC systems except PDSF.

For many years, ExxonMobil has undertaken voluntary actions to improve efficiency in our operations and in customer use of our products. Our Global Energy Management System (GEMS) is an important initiative that is having a positive impact at each of our refineries and chemical plants. The system builds on international best practices and benchmarking to identify energy efficiencies. Launched in 2000, it utilizes a common methodology to identify performance gaps, implement closure plans, sustain progress, and drive energy efficiency toward leading-edge performance. The GEMS business model is based on a three-step approach to performance improvement. First, it addresses base case performance issues by operating existing facilities optimally and efficiently through application of best practices. Second, it identifies economic investment opportunities above an optimized base for step-change improvement to address structural differences. Third, the system implements strong management systems to provide the rigor and discipline necessary to sustain progress and drive continuous improvement. Ultimately, management leadership, organizational commitment, and personal accountability all work together to drive continuous improvement.

UNCERTAINTY IN THE GLOBAL FORECAST SYSTEM  

SciTech Connect

We validated one year of Global Forecast System (GFS) predictions of surface meteorological variables (wind speed, air temperature, dewpoint temperature, air pressure) over the entire planet for forecasts extending from zero hours into the future (an analysis) to 36 hours. Approximately 12,000 surface stations world-wide were included in this analysis. Root-Mean-Square- Errors (RMSE) increased as the forecast period increased from zero to 36 hours, but the initial RMSE were almost as large as the 36 hour forecast RMSE for all variables. Typical RMSE were 3 C for air temperature, 2-3mb for sea-level pressure, 3.5 C for dewpoint temperature and 2.5 m/s for wind speed. Approximately 20-40% of the GFS errors can be attributed to a lack of resolution of local features. We attribute the large initial RMSE for the zero hour forecasts to the inability of the GFS to resolve local terrain features that often dominate local weather conditions, e.g., mountain- valley circulations and sea and land breezes. Since the horizontal resolution of the GFS (about 1{sup o} of latitude and longitude) prevents it from simulating these locally-driven circulations, its performance will not improve until model resolution increases by a factor of 10 or more (from about 100 km to less than 10 km). Since this will not happen in the near future, an alternative for the near term to improve surface weather analyses and predictions for specific points in space and time would be implementation of a high-resolution, limited-area mesoscale atmospheric prediction model in regions of interest.

Growth Rates of Global Energy Systems and Future Outlooks  

Science Conference Proceedings (OSTI)

The world is interconnected and powered by a number of global energy systems using fossil, nuclear, or renewable energy. This study reviews historical time series of energy production and growth for various energy sources. It compiles a theoretical and empirical foundation for understanding the behaviour underlying global energy systems' growth. The most extreme growth rates are found in fossil fuels. The presence of scaling behaviour, i.e. proportionality between growth rate and size, is established. The findings are used to investigate the consistency of several long-range scenarios expecting rapid growth for future energy systems. The validity of such projections is questioned, based on past experience. Finally, it is found that even if new energy systems undergo a rapid 'oil boom'-development-i.e. they mimic the most extreme historical events-their contribution to global energy supply by 2050 will be marginal.

Impact of Distributed Energy Resources on the Reliability of a Critical Telecommunications Facility  

DOE Green Energy (OSTI)

Telecommunications has been identified by the Department of Homeland Security as a critical infrastructure to the United States. Failures in the power systems supporting major telecommunications service nodes are a main contributor to major telecommunications outages, as documented by analyses of Federal Communications Commission (FCC) outage reports by the National Reliability Steering Committee (under auspices of the Alliance for Telecommunications Industry Solutions). There are two major issues that are having increasing impact on the sensitivity of the power distribution to telecommunication facilities: deregulation of the power industry, and changing weather patterns. A logical approach to improve the robustness of telecommunication facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. But does the diversity in power sources actually increase the reliability of offered power to the office equipment, or does the complexity of installing and managing the extended power system induce more potential faults and higher failure rates? This report analyzes a system involving a telecommunications facility consisting of two switch-bays and a satellite reception system.

Setting the global thermostat with an exhaustible tradeable permit system  

SciTech Connect

The global warming policy debate has centered largely on near-term objectives such as freezing 1990 CO{sub 2} emissions without regard to long-run implications. A policy of freezing CO{sub 2} emissions is shown to slow but not halt global warming, while requiring expensive near-term adjustments. If the long-run temperature change outcome of the freeze policy is set as the goal of a more graduated control policy, one which allows the market to determine annual emissions, a more cost-effective solution is obtained that reduces the negative adjustment effects on the energy and other affected industries. The most cost-effective emissions time path of a graduated control policy could be achieved by an evaporative marketable CO{sub 2} emissions permit system. This paper provides a preliminary examination of an evaporative permit system used to achieve long-run stabilization of greenhouse-induced temperature change.

Impact of Distributed Energy Resources on the Reliability of Critical Telecommunications Facilities: Preprint  

DOE Green Energy (OSTI)

This paper documents a probabilistic risk assessment of existing and alternative power supply systems at a large telecommunications office. The analysis characterizes the increase in the reliability of power supply through the use of two alternative power configurations. Failures in the power systems supporting major telecommunications service nodes are a main contributor to significant telecommunications outages. A logical approach to improving the robustness of telecommunication facilities is to increase the depth and breadth of technologies available to restore power during power outages. Distributed energy resources such as fuel cells and gas turbines could provide additional on-site electric power sources to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented.

Memorandum on Land Use Change and the Global Food System  

E-Print Network (OSTI)

The LUC (Land Use Change) term in an LCA assessment of a biofuel’s global warming effect (GW), while superposable for small excursions, is not independent of other events in the global food system. In particular, the GW effect of biofuel use resulting from remote land use change mediated by global grain markets is probably larger to the extent that food supplies are under pressure from whatever other causes. Fuel use of any inputs to food production, especially land, unambiguously causes an increase in food prices relative to what they would otherwise be as long as the demand curve for food slopes upward to the left. Limited opportunities do exist for what are termed ‘pro-poor ’ land use strategies; namely positve, synergestic, interactions of biofuel production and food availability. An example from Africa is included in this memo. Past experience with the ‘Green Revolution ’ of agricultural intensification suggests, however, that the chance to improve the sitation of the global poor can be exceedingly difficult to implement. Discussion Current analysis of the global warming (GW) effect resulting from the substitution of biofuels for petroleum recognizes that land use change (LUC) remote in space (and possibly time) induced by competition with food consumption for biofeedstocks may be large, and that the carbon releases from these changes may not only reduce the GW advantage of [some] biofuels over petroleum but actually reverse it. The discussion has been especially influenced by two recent journal articles (Fargione, Hill, Tilman, Polasky, & Hawthorne, 2008; Searchinger et al., 2007). Because LUC is ‘caused ’ directly by price changes for food crops, discussion of policy implications, including especially discussion in the popular press (for example, (Garber, 2008)), has noted the rapid worldwide increase in food prices, especially grains, over the past two or three years. A good part of that discussion comprises contradictory assertions about whether the increase in US corn ethanol production is responsible for the increases, part of them, or very little. Other

Global Conservation Laws and Femtoscopy of Small Systems  

E-Print Network (OSTI)

It is increasingly important to understand, in detail, two-pion correlations measured in p+p and d+A collisions. In particular, one wishes to understand the femtoscopic correlations, in order to compare to similar measurements in heavy ion collisions. However, in the low-multiplicity final states of these systems, global conservation laws generate significant N-body correlations which project onto the two-pion space in non-trivial ways and complicate the femtoscopic analysis. We discuss a model-independent formalism to calculate and account for these correlations in measurements.

Extending the Operating System at the User Level: the Ufo Global File System  

E-Print Network (OSTI)

In this paper we show how to extend the functionality of standard operating systems completely at the user level. Our approach works by intercepting selected system calls at the user level, using tracing facilities such as the /proc file system provided by many Unix operating systems. The behavior of some intercepted system calls is then modified to implement new functionality. This approach does not require any re-linking or recompilation of existing applications. In fact, the extensions can even be dynamically "installed" into already running processes. The extensions work completely at the user level and install without system administrator assistance. We used this approach to implement a global file system, called Ufo, which allows users to treat remote files exactly as if they were local. Currently, Ufo supports file access through the FTP and HTTP protocols and allows new protocols to be plugged in. While several other projects have implemented global file system abstractions, t...

Global structual optimizations of surface systems with a genetic algorithm  

SciTech Connect

Global structural optimizations with a genetic algorithm were performed for atomic cluster and surface systems including aluminum atomic clusters, Si magic clusters on the Si(111) 7 x 7 surface, silicon high-index surfaces, and Ag-induced Si(111) reconstructions. First, the global structural optimizations of neutral aluminum clusters Al{sub n} (n up to 23) were performed using a genetic algorithm coupled with a tight-binding potential. Second, a genetic algorithm in combination with tight-binding and first-principles calculations were performed to study the structures of magic clusters on the Si(111) 7 x 7 surface. Extensive calculations show that the magic cluster observed in scanning tunneling microscopy (STM) experiments consist of eight Si atoms. Simulated STM images of the Si magic cluster exhibit a ring-like feature similar to STM experiments. Third, a genetic algorithm coupled with a highly optimized empirical potential were used to determine the lowest energy structure of high-index semiconductor surfaces. The lowest energy structures of Si(105) and Si(114) were determined successfully. The results of Si(105) and Si(114) are reported within the framework of highly optimized empirical potential and first-principles calculations. Finally, a genetic algorithm coupled with Si and Ag tight-binding potentials were used to search for Ag-induced Si(111) reconstructions at various Ag and Si coverages. The optimized structural models of {radical}3 x {radical}3, 3 x 1, and 5 x 2 phases were reported using first-principles calculations. A novel model is found to have lower surface energy than the proposed double-honeycomb chained (DHC) model both for Au/Si(111) 5 x 2 and Ag/Si(111) 5 x 2 systems.

The global distribution of large subaerial distributary fluvial systems  

E-Print Network (OSTI)

Large subaerial distributary fluvial systems are cone-shaped, alluvial deposits that are ubiquitous features on Earth. These non-marine, non-lacustrine deposits have superficial similarities to small alluvial fans but are at a scale that is orders of magnitude larger. A variety of terms have been used to identify these features, including alluvial cone, inland delta, wet alluvial fan, humid alluvial fan, alluvial fan, subaerial fan, terminal fan, and megafan. The first systematic examination of these features was presented by Wilkinson et al. (1997). This thesis attempts to provide a more detailed characterization and classification of these features. Fourteen systems in South America, Africa, and Asia were examined using Shuttle photography and AVHRR imagery. This study included: (1) maps of each system and their global distribution, (2) morphometric analyses, (3) classifications by climate, geology, and hydrology, and (4) a comparison to other fluvial systems. These systems have areas 8,881 to 239,583 km², radii 130 to 806 km, and slopes 0.00006 to 0.00079. Active and former river channel patterns on these features suggest that they formed by the action of a single river avulsing across the feature. The area of these features is unrelated to the area of the upstream drainage basin, but is related to the size of the downstream basin. This sample of systems occurs in a variety of climates and in two different geologic settings - foreland basins and half graben. The rivers on all systems are orientated transverse to the trend of the adjacent mountain range or fault. A variety of channel patterns are found on these systems. Considering the definitions of alluvial fans, rivers, and deltas, these systems are best classified as a specific variety of alluvial fan. A new alluvial fan classification scheme more inclusive than that proposed by Stanistreet and McCarthy (1993) is needed. The adoption of a common term to describe these systems - such as megafan - would help to eliminate some of the definitional ambiguities between them and other alluvial fans. Knowledge of these features will enhance our ability to interpret analogous features in the rock record, including important petroleum and water aquifers (e.g., the Ogallala Formation).

GLOBAL OPTIMIZATION METHODS FOR GRAVITATIONAL LENS SYSTEMS WITH REGULARIZED SOURCES  

SciTech Connect

Several approaches exist to model gravitational lens systems. In this study, we apply global optimization methods to find the optimal set of lens parameters using a genetic algorithm. We treat the full optimization procedure as a two-step process: an analytical description of the source plane intensity distribution is used to find an initial approximation to the optimal lens parameters; the second stage of the optimization uses a pixelated source plane with the semilinear method to determine an optimal source. Regularization is handled by means of an iterative method and the generalized cross validation (GCV) and unbiased predictive risk estimator (UPRE) functions that are commonly used in standard image deconvolution problems. This approach simultaneously estimates the optimal regularization parameter and the number of degrees of freedom in the source. Using the GCV and UPRE functions, we are able to justify an estimation of the number of source degrees of freedom found in previous work. We test our approach by applying our code to a subset of the lens systems included in the SLACS survey.

Impact of distributed energy resources on the reliability of a critical telecommunications facility.  

DOE Green Energy (OSTI)

This report documents a probabilistic risk assessment of an existing power supply system at a large telecommunications office. The focus is on characterizing the increase in the reliability of power supply through the use of two alternative power configurations. Telecommunications has been identified by the Department of Homeland Security as a critical infrastructure to the United States. Failures in the power systems supporting major telecommunications service nodes are a main contributor to major telecommunications outages. A logical approach to improve the robustness of telecommunication facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. The analysis is based on a hierarchical Bayesian approach and focuses on the failure probability associated with each of three possible facility configurations, along with assessment of the uncertainty or confidence level in the probability of failure. A risk-based characterization of final best configuration is presented.

Ufo: A Personal Global File System Based on User-Level Extensions to the Operating System  

E-Print Network (OSTI)

In this article we show how to extend a wide range of functionality of standard operating systems completely at the user level. Our approach works by intercepting selected system calls at the user level, using tracing facilities such as the /proc file system provided by many Unix operating systems. The behavior of some intercepted system calls is then modified to implement new functionality. This approach does not require any relinking or recompilation of existing applications. In fact, the extensions can even be dynamically "installed" into already running processes. The extensions work completely at the user level and install without system administrator assistance. Individual users can choose what extensions to run, in effect creating a personalized operating system view for themselves. We used this approach to implement a global file system, called Ufo, which allows users to treat remote files exactly as if they were local. Currently, Ufo supports file access through the FTP and HTTP protocols and allows new protocols to be plugged in. While several other projects have implemented global file system abstractions, they all require either changes to the operating system or modifications to standard libraries. The article gives a detailed performance analysis of our approach to extending the OS and establishes that Ufo introduces acceptable overhead for common applications even though intercepting individual system calls incurs a high cost.

Collaborative Management of Global Directories in P2P Systems  

E-Print Network (OSTI)

To date, much of the research in P2P information sharing has concentrated on methods for key-based or contentbased location of shared information. In this paper, we argue that in addition to these techniques, the provision of a global browsable structure is also a critical component since users do not always know the appropriate key or set of keywords to locate needed information. To give substance to our argument, we propose a framework that will provide P2P communities with global browsable directories. Our proposal focuses specifically on how to support the communal organization and management of such a shared global directory in order to provide a coherent structure for users in a community to locate information via browsing.

E-Print Network (OSTI)

System Optimization is a new approach to HVAC control as implemented by Energy Management Control Systems. System Optimization is defined as electronic building control strategies which treat a building's HVAC components as a complete energy-efficient and coordinated system. Trends in the development of HVAC control strategies are briefly discussed. An example which differentiates between conventional and System Optimization approaches is used to illustrate this new approach. The example discusses aspects of cooling season operation for a typical HVAC system. The paper concludes with four basic principles of System Optimization which are essential for effective control of a building environment.

Complex Adaptive Systems of Systems (CASoS) engineering and foundations for global design.  

SciTech Connect

Complex Adaptive Systems of Systems, or CASoS, are vastly complex ecological, sociological, economic and/or technical systems which must be recognized and reckoned with to design a secure future for the nation and the world. Design within CASoS requires the fostering of a new discipline, CASoS Engineering, and the building of capability to support it. Towards this primary objective, we created the Phoenix Pilot as a crucible from which systemization of the new discipline could emerge. Using a wide range of applications, Phoenix has begun building both theoretical foundations and capability for: the integration of Applications to continuously build common understanding and capability; a Framework for defining problems, designing and testing solutions, and actualizing these solutions within the CASoS of interest; and an engineering Environment required for 'the doing' of CASoS Engineering. In a secondary objective, we applied CASoS Engineering principles to begin to build a foundation for design in context of Global CASoS

Laying the Groundwork: Lessons Learned from the Telecommunications Industry for Distributed Generation; Preprint  

SciTech Connect

The telecommunications industry went through growing pains in the past that hold some interesting lessons for the growing distributed generation (DG) industry. The technology shifts and stakeholders involved with the historic market transformation of the telecommunications sector mirror similar factors involved in distributed generation today. An examination of these factors may inform best practices when approaching the conduits necessary to accelerate the shifting of our nation's energy system to cleaner forms of generation and use. From a technical perspective, the telecom industry in the 1990s saw a shift from highly centralized systems that had no capacity for adaptation to highly adaptive, distributed network systems. From a management perspective, the industry shifted from small, private-company structures to big, capital-intensive corporations. This presentation will explore potential correlation and outline the lessons that we can take away from this comparison.

Computer demonstration of an interactive modeling system for the study of global change and biogeochemistry  

SciTech Connect

There is a need for visually oriented materials to aid in the study of global ecological science. Analysis of the carbon cycle is key to understanding Potential climate change. We have used satellite imagery along with global climate and soil texture data sets to simulate seasonal patterns in net carbon fixation and soil CO[sub 2] production. An interactive computer system is used to illustrate graphical results from various model scenarios of climate warming and land use change. These include global animations of monthly gridded CO[sub 2] exchange between the atmosphere and the terrestrial biosphere. This modeling demonstration highlights the importance of annual CO[sub 2] fluxes in tropical forests (40% of global totals) and the large carbon storage potential in boreal and arctic soils.

Has Globalization Strengthened South Korea’s National Research System  

E-Print Network (OSTI)

We trace the structural patterns of co-authorship between Korean researchers at three institutional types (University, Government, and Industry) and their international partners in terms of the mutual information generated in these relations. Data were collected from the Web of Science during the period 1968-2009. The traditional Triple-Helix indicator was modified to measure the evolving network of co-authorship relations.. The results show that international co-authorship relations have varied considerably over time and with changes in government policies, but most relations have become stable since the early 2000s. In other words, the national publication system of Korea has gained some synergy from R&D internationalization during the 1990s, but the development seems to stagnate particularly at the national level: whereas both university and industrial collaborations are internationalized, the cross-connection within Korea has steadily eroded.

Description of Atmospheric Conditions at the Pierre Auger Observatory using the Global Data Assimilation System (GDAS)  

Science Conference Proceedings (OSTI)

Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargue and averaged monthly models, the utility of the GDAS data is shown.

Evaluating the Cloud Cover Forecast of NCEP Global Forecast System with Satellite Observation  

E-Print Network (OSTI)

To assess the quality of daily cloud cover forecast generated by the operational global numeric model, the NCEP Global Forecast System (GFS), we compose a large sample with outputs from GFS model and satellite observations from the International Satellite Cloud Climatology Project (ISCCP) in the period of July 2004 to June 2008, to conduct a quantitative and systematic assessment of the performance of a cloud model that covers a relatively long range of time, basic cloud types, and in a global view. The evaluation has revealed the goodness of the model forecast, which further illustrates our completeness on understanding cloud generation mechanism. To quantity the result, we found a remarkably high correlation between the model forecasts and the satellite observations over the entire globe, with mean forecast error less than 15% in most areas. Considering a forecast within 30% difference to the observation to be a "good" one, we find that the probability for the GFS model to make good forecasts varies between...

Global generalized synchronization in networks of different time-delay systems  

E-Print Network (OSTI)

We show that global generalized synchronization (GS) exists in structurally different time-delay systems, even with different orders, with quite different fractal (Kaplan-Yorke) dimensions, which emerges via partial GS in symmetrically coupled regular networks. We find that there exists a smooth transformation in such systems, which maps them to a common GS manifold as corroborated by their maximal transverse Lyapunov exponent. In addition, an analytical stability condition using the Krasvoskii-Lyapunov theory is deduced. This phenomenon of GS in strongly distinct systems opens a new way for an effective control of pathological synchronous activity by means of extremely small perturbations to appropriate variables in the synchronization manifold.

Global Solutions of Hartree-Fock Theory and their Consequences for Strongly Correlated Quantum Systems  

E-Print Network (OSTI)

We present a density matrix approach for computing global solutions of Hartree-Fock theory, based on semidefinite programming (SDP), that gives upper and lower bounds on the Hartree-Fock energy of quantum systems. Equality of the upper- and lower-bound energies guarantees that the computed solution is the globally optimal solution of Hartree-Fock theory. For strongly correlated systems the SDP approach requires us to reassess the accuracy of the Hartree-Fock energies and densities from standard software packages for electronic structure theory. Calculations of the H$_{4}$ dimer and N$_{2}$ molecule show that the energies from SDP Hartree-Fock are lower than those from standard Hartree-Fock methods by 100-200 kcal/mol in the dissociation region. The present findings have important consequences for the computation and interpretation of electron correlation, which is typically defined relative to the Hartree-Fock energy and density.

The Global Impact of the Systemic Economies and MENA Business Cycles ?  

E-Print Network (OSTI)

This paper analyzes spillovers from macroeconomic shocks in systemic economies (China, the Euro Area, and the United States) to the Middle East and North Africa (MENA) region as well as outward spillovers from a GDP shock in the Gulf Cooperation Council (GCC) countries and MENA oil exporters to the rest of the world. This analysis is based on a Global Vector Autoregression (GVAR) model, estimated for 38 countries/regions over the period 1979Q2 to 2011Q2. Spillovers are transmitted across economies via trade, financial, and commodity price linkages. The results show that the MENA countries are becoming more sensitive to developments in China than to shocks in the Euro Area or the United States, in line with the direction of evolving trade patterns and the emergence of China as a key driver of the global economy. Outward spillovers from the GCC region and MENA oil exporters are likely to be stronger in their immediate geographical proximity, but also have global implications.

The global unified parallel file system (GUPFS) project: FY 2002 activities and results  

Science Conference Proceedings (OSTI)

The Global Unified Parallel File System (GUPFS) project is a multiple-phase, five-year project at the National Energy Research Scientific Computing (NERSC) Center to provide a scalable, high performance, high bandwidth, shared file system for all the NERSC production computing and support systems. The primary purpose of the GUPFS project is to make it easier to conduct advanced scientific research using the NERSC systems. This is to be accomplished through the use of a shared file system providing a unified file namespace, operating on consolidated shared storage that is directly accessed by all the NERSC production computing and support systems. During its first year, FY 2002, the GUPFS project focused on identifying, testing, and evaluating existing and emerging shared/cluster file system, SAN fabric, and storage technologies; identifying NERSC user input/output (I/O) requirements, methods, and mechanisms; and developing appropriate benchmarking methodologies and benchmark codes for a parallel environment. This report presents the activities and progress of the GUPFS project during its first year, the results of the evaluations conducted, and plans for near-term and longer-term investigations.

Development of the first nonhydrostatic nested-grid grid-point global atmospheric modeling system on parallel machines  

SciTech Connect

This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Evaluating the importance of global and regional climate response to increasing atmospheric concentrations of greenhouse gases requires a comprehensive global atmospheric modeling system (GAMS) capable of simulations over a wide range of atmospheric circulations, from complex terrain to continental scales, on high-performance computers. Unfortunately, all of the existing global circulation models (GCMs) do not meet this requirements, because they suffer from one or more of the following three shortcomings: (1) use of the hydrostatic approximation, which makes the models potentially ill-posed; (2) lack of a nested-grid (or multi-grid) capability, which makes it difficult to consistently evaluate the regional climate response to the global warming, and (3) spherical spectral (opposed to grid-point finite-difference) representation of model variables, which hinders model performance for parallel machine applications. The end product of the research is a highly modularized, multi-gridded, self-calibratable (for further parameterization development) global modeling system with state-of-the-science physics and chemistry. This system will be suitable for a suite of atmospheric problems: from local circulations to climate, from thunderstorms to global cloud radiative forcing, from urban pollution to global greenhouse trace gases, and from the guiding of field experiments to coupling with ocean models. It will also provide a unique testbed for high-performance computing architecture.

Radiation Effects in the Space Telecommunications Environment  

SciTech Connect

Trapped protons and electrons in the Earth's radiation belts and cosmic rays present significant challenges for electronics that must operate reliably in the natural space environment. Single event effects (SEE) can lead to sudden device or system failure, and total dose effects can reduce the lifetime of a telecommmiications system with significant space assets. One of the greatest sources of uncertainty in developing radiation requirements for a space system is accounting for the small but finite probability that the system will be exposed to a massive solar particle event. Once specifications are decided, standard laboratory tests are available to predict the total dose response of MOS and bipolar components in space, but SEE testing of components can be more challenging. Prospects are discussed for device modeling and for the use of standard commercial electronics in space.

Diversity-induced resonance in a system of globally coupled linear oscillators  

E-Print Network (OSTI)

The purpose of this paper to analyze in some detail the arguably simplest case of diversity-induced reseonance: that of a system of globally-coupled linear oscillators subjected to a periodic forcing. Diversity appears as the parameters characterizing each oscillator, namely its mass, internal frequency and damping coefficient are drawn from a probability distribution. The main ingredients for the diversity-induced-resonance phenomenon are present in this system as the oscillators display a variability in the individual responses but are induced, by the coupling, to synchronize their responses. A steady state solution for this model is obtained. We also determine the conditions under which it is possible to find a resonance effect.

Approaches for a quantum memory at telecommunication wavelengths  

Science Conference Proceedings (OSTI)

We report experimental storage and retrieval of weak coherent states of light at telecommunication wavelengths using erbium ions doped into a solid. We use two photon-echo-based quantum storage protocols. The first one is based on controlled reversible inhomogeneous broadening (CRIB). It allows the retrieval of the light on demand by controlling the collective atomic coherence with an external electric field, via the linear Stark effect. We study how atoms in the excited state affect the signal-to-noise ratio of the CRIB memory. Additionally we show how CRIB can be used to modify the temporal width of the retrieved light pulse. The second protocol is based on atomic frequency combs. Using this protocol we verify that the reversible mapping is phase preserving by performing an interference experiment with a local oscillator. These measurements are enabling steps toward solid-state quantum memories at telecommunication wavelengths. We also give an outlook on possible improvements.

The global unified parallel file system (GUPFS) project: FY 2003 activities and results  

Science Conference Proceedings (OSTI)

The Global Unified Parallel File System (GUPFS) project is a multiple-phase project at the National Energy Research Scientific Computing (NERSC) Center whose goal is to provide a scalable, high-performance, high-bandwidth, shared file system for all of the NERSC production computing and support systems. The primary purpose of the GUPFS project is to make the scientific users more productive as they conduct advanced scientific research at NERSC by simplifying the scientists' data management tasks and maximizing storage and data availability. This is to be accomplished through the use of a shared file system providing a unified file namespace, operating on consolidated shared storage that is accessible by all the NERSC production computing and support systems. In order to successfully deploy a scalable high-performance shared file system with consolidated disk storage, three major emerging technologies must be brought together: (1) shared/cluster file systems software, (2) cost-effective, high-performance storage area network (SAN) fabrics, and (3) high-performance storage devices. Although they are evolving rapidly, these emerging technologies individually are not targeted towards the needs of scientific high-performance computing (HPC). The GUPFS project is in the process of assessing these emerging technologies to determine the best combination of solutions for a center-wide shared file system, to encourage the development of these technologies in directions needed for HPC, particularly at NERSC, and to then put them into service. With the development of an evaluation methodology and benchmark suites, and with the updating of the GUPFS testbed system, the project did a substantial number of investigations and evaluations during FY 2003. The investigations and evaluations involved many vendors and products. From our evaluation of these products, we have found that most vendors and many of the products are more focused on the commercial market. Most vendors lack the understanding of, or do not have the resources to pay enough attention to, the needs of high-performance computing environments such as NERSC.

Using reference frames and the Global Positioning System (GPS) to produce control networks for spatial data  

E-Print Network (OSTI)

The Global Positioning System has enabled researchers to gather spatial data on a scale that was, until recently, cost prohibitive. Projects that cover an area of a few hectares can be included in data sets that cover entire countries. The ease at which point locations can be measured over large distances has highlighted an existing problem with data capture. Data collected using one set of control points may or may not overlay data collected using another. This thesis details a procedure for setting base control points that cover very large areas. Data obtained from the International GPS Service for Geodynamics (IGS) is used in conjunction with the International Terrestrial Reference Frame (ITRF) to establish control points anywhere in the world. Researchers utilizing these control points for base station locations or as registration points, are able to produce data with an absolute accuracy of 0.3 meter between projects, countries and continents. The problem of overlaying data has been reduced to the point that it is insignificant. Issues of datum and projections, and the use of existing data sets are addressed. Of special interest are the short project times and resulting cost savings over conventional methods. Specific projects in Texas, Azerbaijan, and Mali are presented. The project in Texas is the same size as the project in Azerbaijan, but on different continents. The project in Mali is much larger and has been the most comprehensive, from setting initial control points to training local researchers in data collection.

Measurement techniques for local and global fluid dynamic quantities in two and three phase systems  

SciTech Connect

This report presents a critical review of the methods available for assessing the fluid dynamic parameters in large industrial two and three phase bubble column and slurry bubble column reactors operated at high pressure and temperature. The physical principles behind various methods are explained, and the basic design of the instrumentation needed to implement each measurement principle is discussed. Fluid dynamic properties of interest are: gas, liquid and solids holdup and their axial and radial distribution as well as the velocity distribution of the two (bubble column) or three phases (slurry bubble column). This information on operating pilot plant and plant reactors is essential to verify the computational fluid dynamic codes as well as scale-up rules used in reactor design. Without such information extensive and costly scale-up to large reactors that exploit syngas chemistries, and other reactors in production of fuels and chemicals, cannot be avoided. In this report, available measurement techniques for evaluation of global and local phase holdups, instantaneous and average phase velocities and for the determination of bubble sizes in gas-liquid and gas-liquid-solid systems are reviewed. Advantages and disadvantages of various techniques are discussed. Particular emphasis is placed on identifying methods that can be employed on large scale, thick wall, high pressure and high temperature reactors used in the manufacture of fuels and chemicals from synthesis gas and its derivatives.

A Measurement Management Technology for Improving Energy Efficiency in Data Centers and Telecommunication Facilities  

SciTech Connect

Data center (DC) electricity use is increasing at an annual rate of over 20% and presents a concern for the Information Technology (IT) industry, governments, and the society. A large fraction of the energy use is consumed by the compressor cooling to maintain the recommended operating conditions for IT equipment. The most common way to improve the DC efficiency is achieved by optimally provisioning the cooling power to match the global heat dissipation in the DC. However, at a more granular level, the large range of heat densities of today's IT equipment makes the task of provisioning cooling power optimized to the level of individual computer room air conditioning (CRAC) units much more challenging. Distributed sensing within a DC enables the development of new strategies to improve energy efficiency, such as hot spot elimination through targeted cooling, matching power consumption at rack level with workload schedule, and minimizing power losses. The scope of Measurement and Management Technologies (MMT) is to develop a software tool and the underlying sensing technology to provide critical decision support and control for DC and telecommunication facilities (TF) operations. A key aspect of MMT technology is integration of modeling tools to understand how changes in one operational parameter affect the overall DC response. It is demonstrated that reduced ordered models for DC can generate, in less than 2 seconds computational time, a three dimensional thermal model in a 50 kft{sup 2} DC. This rapid modeling enables real time visualization of the DC conditions and enables 'what if' scenarios simulations to characterize response to 'disturbances'. One such example is thermal zone modeling that matches the cooling power to the heat generated at a local level by identifying DC zones cooled by a specific CRAC. Turning off a CRAC unit can be simulated to understand how the other CRAC utilization changes and how server temperature responds. Several new sensing technologies were added to the existing MMT platform: (1) air contamination (corrosion) sensors, (2) power monitoring, and (3) a wireless environmental sensing network. All three technologies are built on cost effective sensing solutions that increase the density of sensing points and enable high resolution mapping of DCs. The wireless sensing solution enables Air Conditioning Unit (ACU) control while the corrosion sensor enables air side economization and can quantify the risk of IT equipment failure due to air contamination. Validation data for six test sites demonstrate that leveraging MMT energy efficiency solutions combined with industry best practices results in an average of 20% reduction in cooling energy, without major infrastructure upgrades. As an illustration of the unique MMT capabilities, a data center infrastructure efficiency (DCIE) of 87% (industry best operation) was achieved. The technology is commercialized through IBM System and Technology Lab Services that offers MMT as a solution to improve DC energy efficiency. Estimation indicates that deploying MMT in existing DCs can results in an 8 billion kWh savings and projection indicates that constant adoption of MMT can results in obtainable savings of 44 billion kWh in 2035. Negotiations are under way with business partners to commercialize/license the ACU control technology and the new sensor solutions (corrosion and power sensing) to enable third party vendors and developers to leverage the energy efficiency solutions.

Collaborative Proposal: Transforming How Climate System Models are Used: A Global, Multi-Resolution Approach  

SciTech Connect

Despite the great interest in regional modeling for both weather and climate applications, regional modeling is not yet at the stage that it can be used routinely and effectively for climate modeling of the ocean. The overarching goal of this project is to transform how climate models are used by developing and implementing a robust, efficient, and accurate global approach to regional ocean modeling. To achieve this goal, we will use theoretical and computational means to resolve several basic modeling and algorithmic issues. The first task is to develop techniques for transitioning between parameterized and high-fidelity regional ocean models as the discretization grid transitions from coarse to fine regions. The second task is to develop estimates for the error in scientifically relevant quantities of interest that provide a systematic way to automatically determine where refinement is needed in order to obtain accurate simulations of dynamic and tracer transport in regional ocean models. The third task is to develop efficient, accurate, and robust time-stepping schemes for variable spatial resolution discretizations used in regional ocean models of dynamics and tracer transport. The fourth task is to develop frequency-dependent eddy viscosity finite element and discontinuous Galerkin methods and study their performance and effectiveness for simulation of dynamics and tracer transport in regional ocean models. These four projects share common difficulties and will be approach using a common computational and mathematical toolbox. This is a multidisciplinary project involving faculty and postdocs from Colorado State University, Florida State University, and Penn State University along with scientists from Los Alamos National Laboratory. The completion of the tasks listed within the discussion of the four sub-projects will go a long way towards meeting our goal of developing superior regional ocean models that will transform how climate system models are used.

Testing a Coupled Global-limited-area Data Assimilation System Using Observations from the 2004 Pacific Typhoon Season  

E-Print Network (OSTI)

Tropical cyclone (TC) track and intensity forecasts have improved in recent years due to increased model resolution, improved data assimilation, and the rapid increase in the number of routinely assimilated observations over oceans. The data assimilation approach that has received the most attention in recent years is Ensemble Kalman Filtering (EnKF). The most attractive feature of the EnKF is that it uses a fully flow-dependent estimate of the error statistics, which can have important benefits for the analysis of rapidly developing TCs. We implement the Local Ensemble Transform Kalman Filter algorithm, a variation of the EnKF, on a reduced-resolution version of the National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) model and the NCEP Regional Spectral Model (RSM) to build a coupled global-limited area analysis/forecast system. This is the first time, to our knowledge, that such a system is used for the analysis and forecast of tropical cyclones. We use data from summer 2004 to study eight tropical cyclones in the Northwest Pacific. The benchmark data sets that we use to assess the performance of our system are the NCEP Reanalysis and the NCEP Operational GFS analyses from 2004. These benchmark analyses were both obtained by the Statistical Spectral Interpolation, which was the operational data assimilation system of NCEP in 2004. The GFS Operational analysis assimilated a large number of satellite radiance observations in addition to the observations assimilated in our system. All analyses are verified against the Joint Typhoon Warning Center Best Track data set. The errors are calculated for the position and intensity of the TCs. The global component of the ensemble-based system shows improvement in position analysis over the NCEP Reanalysis, but shows no significant difference from the NCEP operational analysis for most of the storm tracks. The regional component of our system improves position analysis over all the global analyses. The intensity analyses, measured by the minimum sea level pressure, are of similar quality in all of the analyses. Regional deterministic forecasts started from our analyses are generally not significantly different from those started from the GFS operational analysis. On average, the regional experiments performed better for longer than 48 h sea level pressure forecasts, while the global forecast performed better in predicting the position for longer than 48 h.

Global Classical Solutions of the Relativistic Vlasov-Darwin System with Small Cauchy Data: the Generalized Variables Approach  

E-Print Network (OSTI)

We show that a smooth, small enough Cauchy datum launches a unique classical solution of the relativistic Vlasov-Darwin (RVD) system globally in time. A similar result is claimed in Comm. Math. Sci. 6, 749-764 (2008) following the work in Int. Mat. Res. Not. 57191, 1-31 (2006). Our proof does not require estimates derived from the conservation of the total energy, nor those previously given on the transverse component of the electric field. These estimates are crucial in the references cited above. Instead, we exploit the formulation of the RVD system in terms of the generalized space and momentum variables. By doing so, we produce a simple a-priori estimate on the transverse component of the electric field. We widen the functional space required for the Cauchy datum to extend the solution globally in time, and we improve decay estimates given in Comm. Math. Sci. 6, 749-764 (2008) on the electromagnetic field and its space derivatives. Our method extends the constructive proof presented in "Collisionless kinetic equations from astrophysics: The Vlasov-Poisson system. Handbook of Differential Equations: Evolutionary Equations, Vol.3, Elsevier, 2007" to solve the Cauchy problem for the Vlasov-Poisson system with a small initial datum.

Forecasting Cloud Cover and Atmospheric Seeing for Astronomical Observing: Application and Evaluation of the Global Forecast System  

E-Print Network (OSTI)

To explore the issue of performing a non-interactive numerical weather forecast with an operational global model in assist of astronomical observing, we use the Xu-Randall cloud scheme and the Trinquet-Vernin AXP seeing model with the global numerical output from the Global Forecast System to generate 3-72h forecasts for cloud coverage and atmospheric seeing, and compare them with sequence observations from 9 sites from different regions of the world with different climatic background in the period of January 2008 to December 2009. The evaluation shows that the proportion of prefect forecast of cloud cover forecast varies from ~50% to ~85%. The probability of cloud detection is estimated to be around ~30% to ~90%, while the false alarm rate is generally moderate and is much lower than the probability of detection in most cases. The seeing forecast has a moderate mean difference (absolute mean difference <0.3" in most cases) and root-mean-square-error or RMSE (0.2"-0.4" in most cases) comparing with the obs...

Development of Low Global Warming Potential Refrigerant Solutions for Commercial Refrigeration Systems using a Life Cycle Climate Performance Design Tool  

SciTech Connect

Commercial refrigeration systems are known to be prone to high leak rates and to consume large amounts of electricity. As such, direct emissions related to refrigerant leakage and indirect emissions resulting from primary energy consumption contribute greatly to their Life Cycle Climate Performance (LCCP). In this paper, an LCCP design tool is used to evaluate the performance of a typical commercial refrigeration system with alternative refrigerants and minor system modifications to provide lower Global Warming Potential (GWP) refrigerant solutions with improved LCCP compared to baseline systems. The LCCP design tool accounts for system performance, ambient temperature, and system load; system performance is evaluated using a validated vapor compression system simulation tool while ambient temperature and system load are devised from a widely used building energy modeling tool (EnergyPlus). The LCCP design tool also accounts for the change in hourly electricity emission rate to yield an accurate prediction of indirect emissions. The analysis shows that conventional commercial refrigeration system life cycle emissions are largely due to direct emissions associated with refrigerant leaks and that system efficiency plays a smaller role in the LCCP. However, as a transition occurs to low GWP refrigerants, the indirect emissions become more relevant. Low GWP refrigerants may not be suitable for drop-in replacements in conventional commercial refrigeration systems; however some mixtures may be introduced as transitional drop-in replacements. These transitional refrigerants have a significantly lower GWP than baseline refrigerants and as such, improved LCCP. The paper concludes with a brief discussion on the tradeoffs between refrigerant GWP, efficiency and capacity.

HPC Global File System Performance Analysis Using A Scientific-Application Derived Benchmark  

Science Conference Proceedings (OSTI)

With the exponential growth of high-fidelity sensor and simulated data, the scientific community is increasingly reliant on ultrascale HPC resources to handle its data analysis requirements. However, to use such extreme computing power effectively, the I/O components must be designed in a balanced fashion, as any architectural bottleneck will quickly render the platform intolerably inefficient. To understand I/O performance of data-intensive applications in realistic computational settings, we develop a lightweight, portable benchmark called MADbench2, which is derived directly from a large-scale Cosmic Microwave Background (CMB) data analysis package. Our study represents one of the most comprehensive I/O analyses of modern parallel file systems, examining a broad range of system architectures and configurations, including Lustre on the Cray XT3, XT4, and Intel Itanium2 clusters; GPFS on IBM Power5 and AMD Opteron platforms; a BlueGene/P installation using GPFS and PVFS2 file systems; and CXFS on the SGI Altix\\-3700. We present extensive synchronous I/O performance data comparing a number of key parameters including concurrency, POSIX- versus MPI-IO, and unique-versus shared-file accesses, using both the default environment as well as highly-tuned I/O parameters. Finally, we explore the potential of asynchronous I/O and show that only the two of the nine evaluated systems benefited from MPI-2's asynchronous MPI-IO. On those systems, experimental results indicate that the computational intensity required to hide I/O effectively is already close to the practical limit of BLAS3 calculations. Overall, our study quantifies vast differences in performance and functionality of parallel file systems across state-of-the-art platforms -- showing I/O rates that vary up to 75x on the examined architectures -- while providing system designers and computational scientists a lightweight tool for conducting further analysis.

Beyond climate-smart agriculture: toward safe operating spaces for global food systems  

SciTech Connect

Agriculture is considered to be climate-smart when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development because of its capacity to unite the agendas of the agriculture, development and climate change communities under one brand. In this opinion piece authored by scientists from a variety of international agricultural and climate research communities, we argue that the concept needs to be evaluated critically because the relationship between the three dimensions is poorly understood, such that practically any improved agricultural practice can be considered climate-smart. This lack of clarity may have contributed to the broad appeal of the concept. From the understanding that we must hold ourselves accountable to demonstrably better meet human needs in the short and long term within foreseeable local and planetary limits, we develop a conceptualization of climate-smart agriculture as agriculture that can be shown to bring us closer to safe operating spaces for agricultural and food systems across spatial and temporal scales. Improvements in the management of agricultural systems that bring us significantly closer to safe operating spaces will require transformations in governance and use of our natural resources, underpinned by enabling political, social and economic conditions beyond incremental changes. Establishing scientifically credible indicators and metrics of long-term safe operating spaces in the context of a changing climate and growing social-ecological challenges is critical to creating the societal demand and political will required to motivate deep transformations. Answering questions on how the needed transformational change can be achieved will require actively setting and testing hypotheses to refine and characterize our concepts of safer spaces for social-ecological systems across scales. This effort will demand prioritizing key areas of innovation, such as (1) improved adaptive management and governance of social-ecological systems; (2) development of meaningful and relevant integrated indicators of social-ecological systems; (3) gathering of quality integrated data, information, knowledge and analytical tools for improved models and scenarios in time frames and at scales relevant for decision-making; and (4) establishment of legitimate and empowered science policy dialogues on local to international scales to facilitate decision making informed by metrics and indicators of safe operating spaces.

Shoreline monitoring program on the Upper Texas Coast utilizing a Real-Time Kinematic Differential Global Positioning System  

E-Print Network (OSTI)

Due to shoreline erosion, approximately seventeen miles of Texas State Highway 87, located in Jefferson County Texas, have been repeatedly destroyed by storms and rebuilt. This thesis describes a shoreline monitoring program developed to obtain a comprehensive data set that will be used to define the coastal erosion problem and assist in the reconstruction of the roadway. An improved survey system similar to a concept developed by Beach et al. (1996) was designed and constructed for this project. This thesis discusses the improved survey system design and testing. The nearshore system utilizes a Real-Time Kinematic Differential Global Positioning System (RTK-DGPS) mounted on a personal watercraft and integrated with a survey quality echo sounder. The nearshore system was tested by repeating transects in the nearshore. The repeatability of the profiles demonstrated a standard deviation of 6.2 cm from the mean absolute difference of 8.0 cm. The beach survey utilizes RTK-DGPS equipment carried by the surveyor in a backpack. The maximum expected error for the beach survey is approximately []4 cm. The system is an accurate, mobile and efficient method to obtain beach profiles. Additional accuracy may be obtained by integrating a motion sensor and CTD profiler. The survey data are processed using commercially available software packages and programs developed for this project. The processed data is integrated and stored in a geographic information system (GIS). The data collected exemplify morphological features indicative of erosion due to overwash. This is consistent with visual observations and numerical model results provided by Howard (1999). The shoreline movement since 1996 is consistent with historical data and is related to storm events. The current research has provided a survey system capable of performing fast, accurate surveys in the nearshore and a baseline data set. The survey system is fully operational and will be instrumental in the ongoing research related to the Highway 87 reconstruction project. The baseline data set, together with sediment analyses data and water level predictions, provides the foundation from which further investigations will be conducted and will provide information that can be used for the design of the new highway.

A Globally Distributed System for Job, Data, and Information Handling for High Energy Physics  

SciTech Connect

The computing infrastructures of the modern high energy physics experiments need to address an unprecedented set of requirements. The collaborations consist of hundreds of members from dozens of institutions around the world and the computing power necessary to analyze the data produced surpasses already the capabilities of any single computing center. A software infrastructure capable of seamlessly integrating dozens of computing centers around the world, enabling computing for a large and dynamical group of users, is of fundamental importance for the production of scientific results. Such a computing infrastructure is called a computational grid. The SAM-Grid offers a solution to these problems for CDF and DZero, two of the largest high energy physics experiments in the world, running at Fermilab. The SAM-Grid integrates standard grid middleware, such as Condor-G and the Globus Toolkit, with software developed at Fermilab, organizing the system in three major components: data handling, job handling, and information management. This dissertation presents the challenges and the solutions provided in such a computing infrastructure.

Application of the 85 GHz ice scattering signature to a global study of mesoscale convective systems  

E-Print Network (OSTI)

It has long been observed that tropical convection tends to cluster, organizing into multicellular mesoscale convective systems (MCS), In convective towers, updrafts on the order of 10 m s-I favor the formation of large, precipitation-sized ice, which strongly scatters upwelling 85 GHz radiation. The 85 GHz brightness temperature is related to the amount of ice in an MCS and, indirectly, to the strength of the updrafts producing the ice. This study used an objective technique to identify MCSs from the Special Sensor Microwave/Imager's 85 GHz channel to describe the size, intensity, and geographic distribution of MCSs between 35'N and 35'S for January, April, July, and October 1993. An MCS was defined as an area at least 2000 km 2 of 85 GHz polarization corrected brightness temperatures 1 0 5 @) MCSS. Over the oceans, median brightness temperature depression was 20-30 K below 225 K, while over land, it was 35-45 K below 225 K. Tropical Africa had the coldest median minimum brightness temperature. The sub-tropical oceans had the warmest median minimum brightness temperatures. MCSs were 35% more frequent over the oceans at sunrise than at sunset, and 60% more frequent over tropical continents at sunset than at sunrise. Both continental and oceanic MCSs tended to be larger at sunrise than at sunset. Continental MCSs tended to be colder at sunset than at sunrise, but oceanic MCSs tended to be marginally colder at sunrise than at sunset. In general, continental MCSs appeared to be smaller and more intense than oceanic MCSS, and the largest and the most intense MCSs occurred more frequently in the sub-tropics.

Mining Web hyperlink data for business information: The case of telecommunications equipment companies  

E-Print Network (OSTI)

Few studies have explored the possibility of mining Web hyperlink data for e-commerce or business information. This study is an attempt to fill this gap. The project selected a group of telecommunications equipment companies and collected data on the number of links pointing to the company Websites (inlinks) and the company’s revenue. A significant correlation between the two variables was found, suggesting that inlinks contain useful business information and can be objects for Web data mining. The project then explored the feasibility of using Web co-link data to map business competition positions. Co-link data (links pointing to a pair of company Websites) were collected and analyzed using multidimensional scaling (MDS). MDS maps correctly clustered these companies into sectors of the telecommunications equipment industry. Data collection was repeated after nine months and the results confirmed the reliability of the methodology developed in the study. 1.

This interface has a potential to work over wide bandwidths, leading to a high-speed interface of frequency conversion. We achieve the conversion of a pico-second visible photon at 780 nm to a 1522-nm photon, and observe that the conversion process retain entanglement between the down-converted photon and another photon.

The Global Grid  

E-Print Network (OSTI)

This paper puts forward the vision that a natural future stage of the electricity network could be a grid spanning the whole planet and connecting most of the large power plants in the world: this is the "Global Grid". The main driving force behind the Global Grid will be the harvesting of remote renewable sources, and its key infrastructure element will be the high capacity long transmission lines. Wind farms and solar power plants will supply load centers with green power over long distances. This paper focusses on the introduction of the concept, showing that a globally interconnected network can be technologically feasible and economically competitive. We further highlight the multiple opportunities emerging from a global electricity network such as smoothing the renewable energy supply and electricity demand, reducing the need for bulk storage, and reducing the volatility of the energy prices. We also discuss possible investment mechanisms and operating schemes. Among others, we envision in such a system...

Global Environmental Benefits Global Environmental Benefits Gasification Systems Global Environmental Benefits Environmental performance for future energy production systems is a much greater factor as emission standards tighten in the United States and worldwide. The outstanding environmental performance of gasification systems makes it an excellent technology for the clean production of electricity and other products. In addition, the reduction of CO2 emissions is one of the major challenges facing industry in response to global climate change. Other countries with coal reserves might potentially import technologies developed in the United States to enable low-cost gasification with carbon capture and EOR or sequestration. Not only will this benefit the U.S. gasification technology industry, but it will also result in a global environmental benefit through more affordable control of greenhouse gases (GHGs). See the U.S. Environmental Protection Agency (EPA) link below for a summary of the impact of fossil fuels without carbon capture on CO2 emissions, on the GHG contributions of different countries, and of the projected impact of developing countries to 2030:

Method and apparatus for routing data in an inter-nodal communications lattice of a massively parallel computer system by dynamic global mapping of contended links  

DOE Patents (OSTI)

A massively parallel nodal computer system periodically collects and broadcasts usage data for an internal communications network. A node sending data over the network makes a global routing determination using the network usage data. Preferably, network usage data comprises an N-bit usage value for each output buffer associated with a network link. An optimum routing is determined by summing the N-bit values associated with each link through which a data packet must pass, and comparing the sums associated with different possible routes.

Beyond telecommuting: A new paradigm for the effect of telecommunications on travel  

Science Conference Proceedings (OSTI)

Conventional wisdom about social and economic behavior holds that the use of telecommunications is a natural substitute for transportation. For example, telephone calls can replace travel to meetings, and facsimile or electronic-mail transmission of documents substitutes for courier or postal delivery. The moving of information can replace the moving of period and goods. Vehicle traffic on the national transportation infrastructure can be replaced by digital traffic on what is now called the National Information Infrastructure (NII). A leading example is telecommuting. This means using telecommunications to replace commuting between home and work. Telecommuting is an optional way of expanding employees` work locations in those circumstances where it yields both improved organizational performance and employee satisfication. Telecommuting accounts for 7.6 million U.S. workers as of early 1993, up 15% from the 6.6 million counted in 1992. The growth of telecommuting has been strong for the past five years. No one has identified any reasons to suggest that this growth will abate in the forseeable future.

Political Embeddedness, Executive Autonomy, Corporate Characteristics, and Financial Malfeasance in Large Telecommunications Companies  

E-Print Network (OSTI)

This thesis examines the causes of financial malfeasance in the largest U.S. telecommunications corporations between 1995 and 2004. Specifically, it examines whether or not the executive compensation package influences the likelihood that a corporation will falsify its financial statements. The methods used are both qualitative and quantitative. I approach the question form a historical point of view and attempt to identify certain salient characteristics within the telecommunications industry that may influence of unethical or illegal activity. The findings support organizational-political embeddedness theory, which suggests that differential social structures create dependencies, incentives, and opportunities to engage in financial malfeasance. The historical analysis shows that neoliberal policies enacted in the mid-1990s resulted in organizational and political structures that permitted managers to engage in financial malfeasance while limiting the efficiency of regulatory bureaucracies. The quantitative analysis yields mixed findings, many of which are consistent with previous research on white-collar crime and financial malfeasance. This article adds to existing literature by outlining significant public policy shifts and the results those shifts may have on specific industries. These findings have important implications for political officials and corporate oversight organizations.

Quantum frequency conversion of quantum memory compatible photons to telecommunication wavelengths  

E-Print Network (OSTI)

We report an experiment demonstrating quantum frequency conversion of weak light pulses compatible with atomic quantum memories to telecommunication wavelengths. We use a PPLN nonlinear waveguide to convert weak coherent states at the single photon level with a duration of 30ns from a wavelength of 780nm to 1552nm. We measure a maximal waveguide internal (external) conversion efficiency eta_int = 0.41 (eta_ext = 0.25), and we show that the signal to noise ratio (SNR) is good enough to reduce the input photon number below 1. In addition, we show that the noise generated by the pump beam in the crystal is proportional to the spectral bandwidth of the device, suggesting that narrower filtering could significantly increase the SNR. Finally, we demonstrate that the quantum frequency converter can operate in the quantum regime by converting a time-bin qubit and measuring the qubit fidelity after conversion.

Evaluation of habitat use by Rocky Mountain elk (Cervus elaphus nelsoni) in north-central New Mexico using global positioning system radio collars  

SciTech Connect

In 1996 the authors initiated a study to identify habitat use in north-central New Mexico by Rocky Mountain elk (Cervus elaphus nelsoni) using global positioning system (GPS) radio collars. They collared six elk in the spring of 1996 with GPS radio collars programmed to obtain locational fixes every 23 h. Between April 1, 1996 and January 7, 1997, they collected >1,200 fixes with an approximately 70% observation rate. They have interfaced GPS locational fixes of elk and detailed vegetation maps using the geographical information system to provide seasonal habitat use within mountainous regions of north-central New Mexico. Based on habitat use and availability analysis, use of grass/shrub and pinon/juniper habitats was generally higher than expected during most seasons and use of forested habitats was lower than expected. Most of the collared elk remained on LANL property year-round. The authors believe the application of GPS collars to elk studies in north-central New Mexico to be a more efficient and effective method than the use of VHF (very-high frequency) radio collars.

The interplay between telecommunications and face-to-face interactions - an initial study using mobile phone data  

E-Print Network (OSTI)

In this study we analyze one year of anonymized telecommunications data for over one million customers from a large European cellphone operator, in order to investigate the relationship between people's calls and their physical location. We discover that more than 90% of users who have called each other have also shared the same space (cell tower), even if they live far apart. Moreover, we find that 69% of users who call each other frequently (at least once per month on average) have shared the same space at the same time - an instance that we call co-location. Co-locations appear highly indicative of coordination calls, which occur just before face-to-face meetings. Their number is highly predictable based on the amount of calls between two users and the distance between their home locations - suggesting a new way to quantify the interplay between telecommunications and face-to-face interactions.

Determination of locational error associated with global positioning system (GPS) radio collars in relation to vegetation and topography in north-central New Mexico  

Science Conference Proceedings (OSTI)

In 1996, a study was initiated to assess seasonal habitat use and movement patterns of Rocky Mountain elk (Cervus elaphus nelsoni) using global positioning system (GPS) radio collars. As part of this study, the authors attempted to assess the accuracies of GPS (non-differentially corrected) positions under various vegetation canopies and terrain conditions with the use of a GPS ``test`` collar. The test collar was activated every twenty minutes to obtain a position location and continuously uplinked to Argos satellites to transfer position data files. They used a Telonics, Inc. uplink receiver to intercept the transmission and view the results of the collar in real time. They placed the collar on a stand equivalent to the neck height of an adult elk and then placed the stand within three different treatment categories: (1) topographical influence (canyon and mesa tops), (2) canopy influence (open and closed canopy), and (3) vegetation type influence (ponderosa pine and pinion pine-juniper). The collar was kept at each location for one hour (usually obtaining three fixes). In addition, the authors used a hand-held GPS to obtain a position of the test collar at the same time and location.

Implementation plan for operating alternatives for the Naval Computer and Telecommunications Station cogeneration facility at Naval Air Station North Island, San Diego, California  

SciTech Connect

The goal of the US Department of Energy (DOE) Federal Energy Management Program (FEMP) is to facilitate energy efficiency improvements at federal facilities. This is accomplished by a balanced program of technology development, facility assessment, and use of cost-sharing procurement mechanisms. Technology development focuses upon the tools, software, and procedures used to identify and evaluate energy efficiency technologies and improvements. For facility assessment, FEMP provides metering equipment and trained analysts to federal agencies exhibiting a commitment to improve energy use efficiency. To assist in procurement of energy efficiency measures, FEMP helps federal agencies devise and implement performance contracting and utility demand-side management strategies. Pacific Northwest Laboratory (PNL) supports the FEMP mission of energy systems modernization. Under this charter, the Laboratory and its contractors work with federal facility energy managers to assess and implement energy efficiency improvements at federal facilities nationwide. The SouthWestern Division of the Naval Facilities Engineering Command, in cooperation with FEMP, has tasked PNL with developing a plan for implementing recommended modifications to the Naval Computer and Telecommunications Station (NCTS) cogeneration plant at the Naval Air Station North Island (NASNI) in San Diego. That plan is detailed in this report.

Making Global Illumination User Friendly Making Global Illumination User Friendly Title Making Global Illumination User Friendly Publication Type Conference Paper LBNL Report Number LBL-37860 Year of Publication 1995 Authors Ward, Gregory J. Conference Name 6th Eurographics Workshop on Rendering Date Published 06/1995 Conference Location Dublin, Ireland Call Number LBL-37860 Abstract Global illumination researchers tend to think in terms of mesh density and sampling frequency, and their software reflects this in its user interface. Advanced rendering systems are rife with long command lines and parameters for tuning the sample densities, thresholds and other algorithm-specific variables, and the novice user is quickly lost in a sea of possibilities. This paper details a successful effort of making one such global illumination system usable by people who understand their problems, even if they do not understand the methods needed to solve them, through an assisted oracle approach. A single program is introduced to map a small set of intuitive control variables to the rendering commands and parameter settings needed to produce the desired output in a reasonable time. This new executive program then serves as the basis for a graphical user interface that is both friendly in its appearance and reliable in its performance. Finally, we conclude with some future directions for improving this interface.

Global interactions, information flow, and chaos synchronization  

E-Print Network (OSTI)

We investigate the relationship between the emergence of chaos synchronization and the information flow in dynamical systems possessing homogeneous or heterogeneous global interactions whose origin can be external (driven systems) or internal (autonomous systems). By employing general models of coupled chaotic maps for such systems, we show that the presence of a homogeneous global field, either external or internal, for all times is not indispensable for achieving complete or generalized synchronization in a system of chaotic elements. Complete synchronization can also appear with heterogeneous global fields; it does not requires the simultaneous sharing of the field by all the elements in a system. We use the normalized mutual information and the information transfer between global and local variables to characterize complete and generalized synchronization. We show that these information measures can characterize both types of synchronized states and also allow to discern the origin of a global interaction field. A synchronization state emerges when a sufficient amount of information provided by a field is shared by all the elements in the system, on the average over long times. Thus, the maximum value of the top-down information transfer can be used as a predictor of synchronization in a system, as a parameter is varied.

Penetration of hydrogen-based energy system and its potential for causing global environmental change: Scoping risk analysis based on life cycle thinking  

SciTech Connect

A hydrogen-based economy seems superficially to be environmentally friendly, and many people have worked toward its realization. Today hydrogen is mainly produced by decarbonizing fossil fuels (e.g. natural gas), and in the future decarbonization of both fossil fuels and biomass will play a leading role in the production of hydrogen. The main purpose of this paper is to suggest the identification of potential environmental risks in terms of 'life cycle thinking' (which considers all aspects from production to utilization) with regard to the hydrogen-based economy to come. Hydrogen production by decarbonization results in CO{sub 2} emissions. The final destination of the recovered CO{sub 2} is uncertain. Furthermore, there is a possibility that hydrogen molecules will escape to the atmosphere, posing risks that could occasion global environmental changes such as depletion of stratospheric ozone, temperature change in the stratosphere and change of the hydrides cycle through global vaporization. Based on the results of simulation, requirements regarding the following items are proposed to minimize potential risks: hydrogen source, production and storage loss.

Implementation of global energy sustainability  

SciTech Connect

The term energy sustainability emerged from the UN Conference on Environment and Development in Rio 1992, when Agenda 21 was formulated and the Global Energy Charter proclaimed. Emission reductions, total energy costing, improved energy efficiency, and sustainable energy systems are the four fundamental principles of the charter. These principles can be implemented in the proposed financial, legal, technical, and education framework. Much has been done in many countries toward the implementation of the Global Energy Charter, but progress has not been fast enough to ease the disastrous effects of the too many ill-conceived energy systems on the environment, climate, and health. Global warming is accelerating, and pollution is worsening, especially in developing countries with their hunger for energy to meet the needs of economic development. Asian cities are now beating all pollution records, and greenhouse gases are visibly changing the climate with rising sea levels, retracting glaciers, and record weather disasters. This article presents why and how energy investments and research money have to be rechanneled into sustainable energy, rather than into the business-as-usual of depleting, unsustainable energy concepts exceeding one trillion dollars per year. This largest of all investment sectors needs much more attention.

Local Operations in qubit arrays via global but periodic Manipulation  

E-Print Network (OSTI)

We provide a scheme for quantum computation in lattice systems via global but periodic manipulation, in which only effective periodic magnetic fields and global nearest neighbor interaction are required. All operations in our scheme are attainable in optical lattice or solid state systems. We also investigate universal quantum operations and quantum simulation in 2 dimensional lattice. We find global manipulations are superior in simulating some nontrivial many body Hamiltonians.

The Leo Archipelago: A System of Earth-Rings for Communications, Mass-Transport to Space, Solar Power, and Control of Global Warming  

E-Print Network (OSTI)

A multi-purpose low-earth-orbit system of rings circling the earth - the "LEO ARCHIPELAGO" - is proposed as a means of solving or bypassing many major problems hindering man's quest to get into space. A fiber-optic ring about the earth would be an initial testing and developmental stage for the ring systems, while providing cash-flow through a LEO-based, high-band-width, world-wide communication system. A Low-Earth-Orbit-based space-elevator system, "Sling-on-a-Ring," is proposed as the crucial developmental stage of the LEO Archipelago. Being a LEO-based heavy-mass lifter, rather than earth- or GEO-based, it is much less massive and therefore less costly than other proposed space-elevators. With the advent of lower-cost, higher-mass transport to orbit, the options for further space development (e.g., communications, space solar power, radiation dampers, sun shades, and permanent LEO habitation) are greatly expanded. This paper provides an update of the Sling-on-a-Ring concept in terms of new materials, potential applications, and trade-offs associated with an earlier model. The impact of Colossal Carbon Tubes, CCT, a material with high tensile strength, extremely-low density, and other favorable properties and new technologies (e.g., solar-powered lasers, power beaming to near-space and earth, and thermal-control systems) on the development of associated LEO-Ring systems (e.g., "Solar-Shade Rings" and "Power Rings") is also explored. The material's effect on the timeline for the system development indicates the feasibility of near-term implementation of the system (possibly within the decade). The Sling-on-a-Ring can provide a less-expensive, environment-friendly, mode of access to space. This would pave the way (via eventual operation at >1000 tonnes per day by 2050) for large scale development of space-based technologies.

Energy Conservation in the Bell System  

E-Print Network (OSTI)

The Bell System provides numerous examples of ways in which demand for energy may be reduced, resulting in conservation of resources and preservation of the environment. The System's telecommunications network links nearly 185 million telephones and handles in excess of 850 million calls a day. In providing telecommunications services, the System employs more than one million people, utilizes 32,000 buildings, and operates more than 190,000 motor vehicles (the world's largest owned and operated private fleet). However, the Bell System is not energy intensive. It uses about one tenth of one percent of the Nation's energy, while contributing over two percent of the gross national product. During 1982, the System used 13 percent less energy than in 1973, although all business indicators increased: volume of business, 97 percent; customer lines, 38 percent; calls, 55 percent; number of motor vehicles, 19 percent; and floor space, 31 percent.

Global irrigation demand - A holistic approach  

Science Conference Proceedings (OSTI)

To develop a research track on global irrigation demand and the use of future water resources to help feed the world, we need to adopt a holistic approach to understand inter-dependencies and the main drivers of the global water system and unravel positive (reinforcing) and negative (balancing) feedback loops that can lead to cascading consequences. Thus, there needs to be more research dedicated to 1) the modeling of the agricultural and water systems as components within an integrated assessment human-Earth modeling framework, 2) the understanding of the linkages between the physical processes and the human system, and to integrate them in an economic framework to capture the dynamics of market price, and institutional regulations. This editorial discusses the importance of tackling the global irrigation problem in an integrated assessment modeling framework.

Global ice sheet modeling  

Science Conference Proceedings (OSTI)

The University of Maine conducted this study for Pacific Northwest Laboratory (PNL) as part of a global climate modeling task for site characterization of the potential nuclear waste respository site at Yucca Mountain, NV. The purpose of the study was to develop a global ice sheet dynamics model that will forecast the three-dimensional configuration of global ice sheets for specific climate change scenarios. The objective of the third (final) year of the work was to produce ice sheet data for glaciation scenarios covering the next 100,000 years. This was accomplished using both the map-plane and flowband solutions of our time-dependent, finite-element gridpoint model. The theory and equations used to develop the ice sheet models are presented. Three future scenarios were simulated by the model and results are discussed.

Integrated Global Nuclear Materials Management - Preliminary Concepts -  

SciTech Connect

Approach to Connect Global Objectives and Local Actions: (1) Articulate global objectives into a hierarchy of subsystem requirements and local attributes and measures; (2) Establish a baseline system and viable alternatives through the interactions and relationships (e.g., networks) of local system elements and their options; (3) Evaluate performance of system alternatives and develop improved nuclear material management strategies and technologies; and (4) The need to address greatest concerns first (prioritized or graded approach) and to make tradeoffs among implementation options and competing objectives entails a risk-based approach. IGNMM could provide a systematic understanding of global nuclear materials management and evolutionarily improve and integrate the management through an active architecture, using for example, situation awareness, system models, methods, technologies, and international cooperation. Different tools would be used within the overall framework to address individual issues on the desired geographic scale that could be easily linked to broader analyses. Life-cycle system analyses would allow for evaluating material path alternatives on an integrated global scale. Disconnects, overlaps, technical options, and alternatives for optimizing nuclear materials processes could be evaluated in an integrated manner.

Global Climate Data  

NLE Websites -- All DOE Office Websites (Extended Search)

Data Data The climate data at the ORNL DAAC are used primarily as driving variables in terrestrial biogeochemistry models. These models typically use data on temperature (min,max), precipitation, humidity (relative humidity, vapor pressure deficit, dew point), radiation (PFD in PAR, shortwave, direct/diffuse, and UV radiation, daylength), and wind velocity. Climate / meteorology data are required at hourly to monthly time scales, either point or gridded, at spatial scales ranging from regional to continental to global. The ORNL DAAC currently distributes climate data from several related projects: VEMAP-1 Hydroclimatology, and Global Historical Climatology Network. We are also now distributing climate data developed at the East Anglia Climate Research Unit and the Potsdam Institute for Climate Research.

Global climate feedbacks  

SciTech Connect

The important physical, chemical, and biological events that affect global climate change occur on a mesoscale -- requiring high spatial resolution for their analysis. The Department of Energy has formulated two major initiatives under the US Global Change Program: ARM (Atmospheric Radiation Measurements), and CHAMMP (Computer Hardware Advanced Mathematics and Model Physics). ARM is designed to use ground and air-craft based observations to document profiles of atmospheric composition, clouds, and radiative fluxes. With research and models of important physical processes, ARM will delineate the relationships between trace gases, aerosol and cloud structure, and radiative transfer in the atmosphere, and will improve the parameterization of global circulation models. The present GCMs do not model important feedbacks, including those from clouds, oceans, and land processes. The purpose of this workshop is to identify such potential feedbacks, to evaluate the uncertainties in the feedback processes (and, if possible, to parameterize the feedback processes so that they can be treated in a GCM), and to recommend research programs that will reduce the uncertainties in important feedback processes. Individual reports are processed separately for the data bases.

Global residential appliance standards  

SciTech Connect

In most countries, residential electricity consumption typically ranges from 20% to 40% of total electricity consumption. This energy is used for heating, cooling, refrigeration and other end-uses. Significant energy savings are possible if new appliance purchases are for models with higher efficiency than that of existing models. There are several ways to ensure or encourage such an outcome, for example, appliance rebates, innovative procurement, and minimum efficiency standards. This paper focuses on the latter approach. At the present time, the US is the only country with comprehensive appliance energy efficiency standards. However, many other countries, such as Australia, Canada, the European Community (EC), Japan and Korea, are considering enacting standards. The greatest potential impact of minimum efficiency standards for appliances is in the developing countries (e.g., China and India), where saturations of household appliances are relatively low but growing rapidly. This paper discusses the potential savings that could be achieved from global appliance efficiency standards for refrigerators and freezers. It also could be achieved from global appliance efficiency standards for refrigerators and freezers. It also discusses the impediments to establishing common standards for certain appliance types, such as differing test procedures, characteristics, and fuel prices. A methodology for establishing global efficiency standards for refrigerators and freezers is described.

Arrhenius and global warming  

SciTech Connect

Although concern about global atmospheric warming has intensified in recent decades, research into the greenhouse effect actually began in the 19th century. Fourier and other scientists appreciated that without heat-absorbing gases in the atmosphere, the temperature on the ground would be considerably lower, making life as we know it impossible. In 1896, the Swedish scientist Svante Arrhenius was the first to make a quantitative link between changes in carbon dioxide concentration and climate. Publication of his paper was celebrated at a recent Swedish workshop. 13 refs., 1 fig.

The Global Energy Challenge  

DOE Green Energy (OSTI)

The expected doubling of global energy demand by 2050 challenges our traditional patterns of energy production, distribution and use. The continued use of fossil fuels raises concerns about supply, security, environment and climate. New routes are needed for the efficient conversion of energy from chemical fuel, sunlight, and heat to electricity or hydrogen as an energy carrier and finally to end uses like transportation, lighting, and heating. Opportunities for efficient new energy conversion routes based on nanoscale materials will be presented, with emphasis on the sustainable energy technologies they enable.

Global emissions inventories  

SciTech Connect

Atmospheric chemistry determines the concentrations of most of the important greenhouse gases except for carbon dioxide. The rate of removal of the greenhouse gases from the atmosphere is also controlled by atmospheric chemistry. The indirect effects of chemical forcing resulting from the chemical interactions of other species can also affect the concentrations of radiatively important gases such as ozone. In order to establish the contribution of any possible climatic change attributable to individual greenhouse gases, spatially and temporally resolved estimates of their emissions need to be established. Unfortunately, for most of the radiatively important species the global magnitudes of their individual fluxes are not known to better than a factor of two and their spatial distributions are even more poorly characterized. Efforts to estimate future projections of potential impacts and to monitor international agreements will require continued research to narrow the uncertainties of magnitude and geographical distribution of emissions.

Global warming and global dioxide emission: An empirical study  

Science Conference Proceedings (OSTI)

In this paper, the dynamic relationship between global surface temperature (global warming) and global carbon dioxide emission (CO{sub 2}) is modelled and analyzed by causality and spectral analysis in the time domain and frequency domain, respectively. Historical data of global CO{sub 2} emission and global surface temperature anomalies over 129 years from 1860-1988 are used in this study. The causal relationship between the two phenomena is first examined using the Sim and Granger causality test in the time domain after the data series are filtered by ARIMA models. The Granger causal relationship is further scrutinized and confirmed by cross-spectral and multichannel spectral analysis in the frequency domain. The evidence found from both analyses proves that there is a positive causal relationship between the two variables. The time domain analysis suggests that Granger causality exists between global surface temperature and global CO{sub 2} emission. Further, CO{sub 2} emission causes the change in temperature. The conclusions are further confirmed by the frequency domain analysis, which indicates that the increase in CO{sub 2} emission causes climate warming because a high coherence exists between the two variables. Furthermore, it is proved that climate changes happen after an increase in CO{sub 2} emission, which confirms that the increase in CO{sub 2} emission does cause global warming. 27 refs., 10 figs., 5 tabs.

The power rating of autonomous systems can range from a few 100 W to about 50 kW. Usually a storage is incorporated in the form of electric batteries or standard night storage heaters, improving considerably the ability of the system to sustain the average power and ameliorate the reliability.

Global production through 2005  

SciTech Connect

Two companion studies released recently should provide great food for thought among geo-political strategists and various national governments. If predictions contained in these Petroconsultants studies of oil and gas production trends for the next 10 years are realized, there will be great repercussions for net exporters and importers, alike. After analyzing and predicting trends within each of the world`s significant producing nations for the 1996--2005 period, the crude oil and condensate report concludes tat global production will jump nearly 24%. By contrast, worldwide gas output will leap 40%. The cast of characters among producers and exporters that will benefit from these increases varies considerably for each fuel. On the oil side, Russia and the OPEC members, particularly the Persian Gulf nations, will be back in the driver`s seat in terms of affecting export and pricing patterns. On the gas side, the leading producers will be an interesting mix of mostly non-OPEC countries. The reemergence of Persian Gulf oil producers, coupled with an anticipated long-term decline among top non-OPEC producing nations should present a sobering picture to government planners within large net importers, such as the US. They are likely to find themselves in much the same supply trap as was experienced in the 1970s, only this time the dependence on foreign oil supplies will be much worse. Gas supplies will not be similarly constrained, and some substitution for oil is probable. Here, two articles, ``World oil industry is set for transition`` and ``Worldwide gas surges forward in next decade,`` present a summary of the findings detailed in Petroconsultants` recent studies.

Using Procedural RenderMan Shaders for Global Illumination  

E-Print Network (OSTI)

Global illumination techniques like radiosity or Monte-Carlo ray-tracing are becoming standard features of rendering systems. However, there is currently no accepted interface format which supports an appropriate physically-based scene description. In this paper we present extensions to the well-known RenderMan interface, which allow for a physically based scene description and support advanced global illumination techniques. Special emphasis has been laid on the support for procedural descriptions of reflection and emission by RenderMan surface shaders. So far, they could not be used with most global illumination algorithms. The extensions have been implemented in a physically-based rendering system and are illustrated with examples. 1. Introduction In recent years physically-based rendering and global illumination have became major topics in computer graphics. While these techniques are on the edge of being used in commercial applications, it is getting more and more important to fi...

Smart Grid Communications System Blueprint  

Science Conference Proceedings (OSTI)

Telecommunications operators are well versed in deploying 2G and 3G wireless networks. These networks presently support the mobile business user and/or retail consumer wishing to place conventional voice calls and data connections. The electrical power industry has recently commenced transformation of its distribution networks by deploying smart monitoring and control devices throughout their networks. This evolution of the network into a ‘smart grid’ has also motivated the need to deploy wireless technologies that bridge the communication gap between the smart devices and information technology systems. The requirements of these networks differ from traditional wireless networks that communications operators have deployed

Energy and environmental aspects of mobile communication systems  

E-Print Network (OSTI)

The reduction of the energy consumptions of a Telecommunication Power System represents one of the critical factors of the telecommunication technologies, both to allow a sizeable saving of economic resources and to realize "sustainable" development actions. The consumption of about one hundred base stations for mobile phones were monitored for a total of over one thousand days, in order to study the energy consumption in relation to the environmental, electric and logistics parameters of the stations themselves. It was possible to survey, then, the role of the mobile communication systems in the general national energy framework and to plot the best areas of intervention for saving energy and improving the environmental impact, showing the role played by air conditioning and transmission equipments. Finally, new transmission algorithms and the use of renewable energy based techniques have been tested.

Aspen Global Change Institute Summer Science Sessions  

Science Conference Proceedings (OSTI)

The Aspen Global Change Institute (AGCI) successfully organized and convened six interdisciplinary meetings over the course of award NNG04GA21G. The topics of the meetings were consistent with a range of issues, goals and objectives as described within the NASA Earth Science Enterprise Strategic Plan and more broadly by the US Global Change Research Program/Our Changing Planet, the more recent Climate Change Program Strategic Plan and the NSF Pathways report. The meetings were chaired by two or more leaders from within the disciplinary focus of each session. 222 scholars for a total of 1097 participants-days were convened under the auspices of this award. The overall goal of each AGCI session is to further the understanding of Earth system science and global environmental change through interdisciplinary dialog. The format and structure of the meetings allows for presentation by each participant, in-depth discussion by the whole group, and smaller working group and synthesis activities. The size of the group is important in terms of the group dynamics and interaction, and the ability for each participant's work to be adequately presented and discussed within the duration of the meeting, while still allowing time for synthesis

Management: Global positioning and wireless dispatching  

Science Conference Proceedings (OSTI)

Over the last several years, my company has been supplying many service companies with wireless dispatching solutions. Recently the impact of the system has been greatly increased with the introduction of a GPS (Global Position Systems) interface. This adds visual recognition as to the whereabouts of each vehicle within the customer service area. The only equipment required in the field for GPS is a transmit/receive device and a wireless modem, one mounted out of the way in the vehicle (under the seat) and a {open_quotes}hockey puck{close_quotes} size unit on the roof of the vehicle. The GPS received unit and wireless modem are used to retrieve the longitude, latitude and ground speed coordinates and transmit them back to the host system.

Quantifying nonclassicality: global impact of local unitary evolutions  

E-Print Network (OSTI)

We show that only those composite quantum systems possessing nonvanishing quantum correlations have the property that any nontrivial local unitary evolution changes their global state. We derive the exact relation between the global state change induced by local unitary evolutions and the amount of quantum correlations. We prove that the minimal change coincides with the geometric measure of discord (defined via the Hilbert- Schmidt norm), thus providing the latter with an operational interpretation in terms of the capability of a local unitary dynamics to modify a global state. We establish that two-qubit Werner states are maximally quantum correlated, and are thus the ones that maximize this type of global quantum effect. Finally, we show that similar results hold when replacing the Hilbert-Schmidt norm with the trace norm.

Global terrestrial biogeochemistry: Perturbations, interactions, and time scales  

Science Conference Proceedings (OSTI)

Global biogeochemical processes are being perturbed by human activity, principally that which is associated with industrial activity and expansion of urban and agricultural complexes. Perturbations have manifested themselves at least since the beginning of the 19th Century, and include emissions of CO{sub 2} and other pollutants from fossil fuel combustion, agricultural emissions of reactive nitrogen, and direct disruption of ecosystem function through land conversion. These perturbations yield local impacts, but there are also global consequences that are the sum of local-scale influences. Several approaches to understanding the global-scale implications of chemical perturbations to the Earth system are discussed. The lifetime of anthropogenic CO{sub 2} in the atmosphere is an important concept for understanding the current and future commitment to an altered atmospheric heat budget. The importance of the terrestrial biogeochemistry relative to the lifetime of excess CO{sub 2} is demonstrated using dynamic, aggregated models of the global carbon cycle.

Global Cooling: Effect of Urban Albedo on Global Temperature  

SciTech Connect

In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). The roof and the pavement albedo can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60%. We estimate U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills. Increasing albedo of urban surfaces can reduce the summertime urban temperature and improve the urban air quality. Increasing the urban albedo has the added benefit of reflecting more of the incoming global solar radiation and countering the effect of global warming. We estimate that increasing albedo of urban areas by 0.1 results in an increase of 3 x 10{sup -4} in Earth albedo. Using a simple global model, the change in air temperature in lowest 1.8 km of the atmosphere is estimated at 0.01K. Modelers predict a warming of about 3K in the next 60 years (0.05K/year). Change of 0.1 in urban albedo will result in 0.01K global cooling, a delay of {approx}0.2 years in global warming. This 0.2 years delay in global warming is equivalent to 10 Gt reduction in CO2 emissions.

Characterizing entanglement with global and marginal entropic measures  

SciTech Connect

We qualify the entanglement of arbitrary mixed states of bipartite quantum systems by comparing global and marginal mixednesses quantified by different entropic measures. For systems of two qubits we discriminate the class of maximally entangled states with fixed marginal mixednesses, and determine an analytical upper bound relating the entanglement of formation to the marginal linear entropies. This result partially generalizes to mixed states the quantification of entanglement with marginal mixednesses holding for pure states. We identify a class of entangled states that, for fixed marginals, are globally more mixed than product states when measured by the linear entropy. Such states cannot be discriminated by the majorization criterion.

Analysis of operating alternatives for the Naval Computer and Telecommunications Station Cogeneration Facility at Naval Air Station North Island, San Diego, California  

SciTech Connect

The Naval Facilities Engineering Command Southwestern Division commissioned Pacific Northwest Laboratory (PNL), in support of the US Department of Energy (DOE) Federal Energy Management Program (FEMP), to determine the most cost-effective approach to the operation of the cogeneration facility in the Naval Computer and Telecommunications Station (NCTS) at the Naval Air Station North Island (NASNI). Nineteen alternative scenarios were analyzed by PNL on a life-cycle cost basis to determine whether to continue operating the cogeneration facility or convert the plant to emergency-generator status. This report provides the results of the analysis performed by PNL for the 19 alternative scenarios. A narrative description of each scenario is provided, including information on the prime mover, electrical generating efficiency, thermal recovery efficiency, operational labor, and backup energy strategy. Descriptions of the energy and energy cost analysis, operations and maintenance (O&M) costs, emissions and related costs, and implementation costs are also provided for each alternative. A summary table presents the operational cost of each scenario and presents the result of the life-cycle cost analysis.

Motor vehicles and global warming  

SciTech Connect

Energy use in transportation is one of the contributors to the concern over global warming. The primary greenhouse gases released by the transportation sector are carbon dioxide and chlorofluorocarbons. When all greenhouse gases are considered, CO{sub 2} emissions from the operation of highway vehicles worldwide represent about 4.7% of global warming enhancement. CO{sub 2} emissions from U.S. highway vehicles along represent about 2 to 2.5% of worldwide greenhouse gases. The use of CFCs in automotive air conditioning, in blowing foams for seats and padding and in the manufacture of electronic circuit boards accounted for 15% of the global usage of CFC-12 in 1985 according to the U.S. EPA. The Motor Vehicle Manufacturers Association supports the phase-out of CFC use provided that safe substitutes are available and that adequate lead time is allowed for.They suggest that reduction of greenhouse gases would require planning on a global scope to be effective. One alternative they suggest for further study is a carbon fee for reducing emissions of carbon dioxide. This fee would be levied on each type of fossil fuel, proportional to its carbon content per unit of energy.

Abstract Developing usable and robust mixed reality systems requires unique human–computer interaction techniques and customized hardware systems. The design of the hardware is directed by the requirements of the rich 3D interactions that can be performed using immersive mobile MR systems. Geometry modeling and capture, navigational annotations, visualizations, and training simulations are all enhanced using augmented computer graphics. We present the design guidelines that have led us through 10 years of evolving mobile outdoor MR hardware systems.

Energy Conservation in the Bell System  

E-Print Network (OSTI)

In December 1973, the Bell System launched a comprehensive energy conservation program which includes immediate, intermediate, and long range steps. A computerized data base system was developed to permit monthly input of energy consumption, costs, and correlating factors, and to provide rapid determination of energy performance. Immediate steps, primarily in building and motor vehicle operations, resulted in approximately 10% energy conservation in 1974 compared with 1973. These, plus intermediate range steps, including replacement of remaining vacuum tubes and beginning the redesign and retrofitting of existing heating and cooling systems, resulted in the Bell System consuming 9% less energy during 1978 than was used in 1973. This reduction in energy use was accomplished while volume of business increased 47% and telephones served increased over 21%. Longer range steps include: introducing more energy efficient telecommunications equipment; improving building environmental systems; adapting alternate energy sources; increasing efficiency of motor vehicles; and expanding materials recycling. These longer range energy conservation steps will permit continued highest quality telecommunications while significantly restricting energy growth. The Bell System is committed to a long range objective of using less energy in 1984 than was used in 1973 even though business is expected to continue growing at approximately the same rate as the prior years.

Global warming continues in 1989  

SciTech Connect

Nineteen eight-nine ranks as one of the warmest years on record despite the chill of unusually cool water in the tropical Pacific. The continued robustness of the warming trend that began in the mid-1970s lends support to claims that an intensifying greenhouse effect is behind it all, although that case has not yet been made definitively. Even at the current rate of global warming it will take another 10 years or so to be confident that the greenhouse effect is with us. Although the global warming trend is consistent with an increasing contribution by the greenhouse effect, direct signs that the greenhouse effect is intensifying are still hard to come by in the temperature record. Greenhouse models agree that if that is happening, the temperature increase should be most pronounced around the Arctic. Alaska, northwestern Canada, and northern Siberia warmed sharply in the 1980s, but the region from eastern Canada through Greenland and into Scandinavia cooled markedly.

Global Technology Regulation and Potentially  

E-Print Network (OSTI)

In 2000 Bill Joy proposed that the best way to prevent technological apocalypse was to "relinquish " emerging bio-, info- and nanotechnologies. His essay introduced many watchdog groups to the dangers that futurists had been warning of for decades. One such group, ETC, has called for a moratorium on all nanotechnological research until all safety issues can be investigated and social impacts ameliorated. In this essay I discuss the differences and similarities of regulating bio- and nanotechnological innovation to the efforts to regulate nuclear and biological weapons of mass destruction. I then suggest the creation of a global technology regulatory regime to ensure the safe and equitable diffusion of genetic, molecular and information technologies, and point out the principal political obstacles to implementing such a regime.

Clean coal: Global opportunities for small businesses  

Science Conference Proceedings (OSTI)

The parallel growth in coal demand and environmental concern has spurred interest in technologies that burn coal with greater efficiency and with lower emissions. Clean Coal Technologies (CCTs) will ensure that continued use of the world`s most abundant energy resource is compatible with a cleaner, healthier environment. Increasing interest in CCTs opens the door for American small businesses to provide services and equipment for the clean and efficient use of coal. Key players in most coal-related projects are typically large equipment manufacturers, power project developers, utilities, governments, and multinational corporations. At the same time, the complexity and scale of many of these projects creates niche markets for small American businesses with high-value products and services. From information technology, control systems, and specialized components to management practices, financial services, and personnel training methods, small US companies boast some of the highest value products and services in the world. As a result, American companies are in a prime position to take advantage of global niche markets for CCTs. This guide is designed to provide US small businesses with an overview of potential international market opportunities related to CCTs and to provide initial guidance on how to cost-effectively enter that growing global market.

Global fish production and climate change  

Science Conference Proceedings (OSTI)

Current global fisheries production of {approx}160 million tons is rising as a result of increases in aquaculture production. A number of climate-related threats to both capture fisheries and aquaculture are identified, but there is low confidence in predictions of future fisheries production because of uncertainty over future global aquatic net primary production and the transfer of this production through the food chain to human consumption. Recent changes in the distribution and productivity of a number of fish species can be ascribed with high confidence to regional climate variability, such as the El Nino-Southern Oscillation. Future production may increase in some high-latitude regions because of warming and decreased ice cover, but the dynamics in low-latitude regions are giverned by different processes, and production may decline as a result of reduced vertical mixing of the water column and, hence, reduced recycling of nutrients. There are strong interactions between the effects of fishing and the effects of climate because fishing reduces the age, size, and geographic diversity of populations and the biodiversity of marine ecosystems, making both more sensitive to additional stresses such as climate change. Inland fisheries are additionally threatened by changes in precipiation and water management. The frequency and intensity of extreme climate events is likely to have a major impact on future fisheries production in both inland and marine systems. Reducing fishing mortality in the majority of fisheries, which are currently fully exploited or overexploited, is the pricipal feasible means of reducing the impacts of climate change.

Development of an Integrated Global Energy Model  

Science Conference Proceedings (OSTI)

The primary objective of this research was to develop a forefront analysis tool for application to enhance understanding of long-term, global, nuclear-energy and nuclear-material futures. To this end, an existing economics-energy-environmental (E{sup 3}) model was adopted, modified, and elaborated to examine this problem in a multi-regional (13), long-term ({approximately}2,100) context. The E{sup 3} model so developed was applied to create a Los Alamos presence in this E{sup 3} area through ''niche analyses'' that provide input to the formulation of policies dealing with and shaping of nuclear-energy and nuclear-materials futures. Results from analyses using the E{sup 3} model have been presented at a variety of national and international conferences and workshops. Through use of the E{sup 3} model Los Alamos was afforded the opportunity to participate in a multi-national E{sup 3} study team that is examining a range of global, long-term nuclear issues under the auspices of the IAEA during the 1998-99 period . Finally, the E{sup 3} model developed under this LDRD project is being used as an important component in more recent Nuclear Material Management Systems (NMMS) project.

Global change research: Summaries of research in FY 1992  

SciTech Connect

Greenhouse gases result from both natural and man-made processes and include carbon dioxide (CO{sub 2}), nitrogen oxides (N{sub x}0{sub y}), methane, chlorofluorocarbons, halogenated compounds, water vapor, and others. Since the industrial revolution, the atmospheric concentrations of several greenhouse gases have been increasing, primarily because of human activities. These increases have the potential to cause global climate change through increased radiative forcing. Global climate change is a significant issue for the Department of Energy (DOE) because energy production and use now contribute more than half of the total man-made emissions of greenhouse gases on a global basis. The missions of the Department`s Global Change Research Program are: To predict the future atmospheric concentrations of CO{sub 2} and other energy-related greenhouse gases; to predict the future and magnitude of potential climate change caused by the enhanced greenhouse effect; to understand both the direct impacts of greenhouse-gas emissions on biota and the indirect consequences produced by climate change; to assess the impacts of global climate change on energy systems and energy demand; and to develop and assess the potential of mitigation and adaptation technologies and practices to offset or limit the impact of any potential climate change or to facilitate natural and societal adjustment to the environmental, social, and economic consequences of global climate changes. The information produced by these activities is necessary in order to assess the economic and environmental costs and benefits of both potential climate change caused by the effects of greenhouse gases and implementing different technologies and energy-policy options aimed at preventing, mitigating, or adapting to such change. This document describes the activities and products of the Global Change Research Program in FY 1992.

A New Global Unconventional Natural Gas Resource Assessment  

E-Print Network (OSTI)

In 1997, Rogner published a paper containing an estimate of the natural gas in place in unconventional reservoirs for 11 world regions. Rogner's work was assessing the unconventional gas resource base, and is now considered to be very conservative. Very little is known publicly about technically recoverable unconventional gas resource potential on a global scale. Driven by a new understanding of the size of gas shale resources in the United States, we estimated original gas in place (OGIP) and technically recoverable resource (TRR) in highly uncertain unconventional gas reservoirs, worldwide. We evaluated global unconventional OGIP by (1) developing theoretical statistic relationships between conventional hydrocarbon and unconventional gas; (2) fitting these relationships to North America publically available data; and (3) applying North American theoretical statistical relationships to evaluate the volume of unconventional gas resource of the world. Estimated global unconventional OGIP ranges from 83,300 (P10) to 184,200 (P90) Tcf. To assess global TRR from unconventional gas reservoirs, we developed a computer program that we call Unconventional Gas Resource Assessment System (UGRAS). In the program, we integrated a Monte Carlo technique with an analytical reservoir simulator to estimate the original volume of gas in place and to predict production performance. We used UGRAS to evaluate the probabilistic distribution of OGIP, TRR and recovery factor (RF) for the most productive unconventional gas formations in the North America. The P50 of recovery factor for shale gas, tight sands gas and coalbed methane is 25%, 79% and 41%, respectively. Finally, we applied our global OGIP assessment and these distributions of recovery factor gained from our analyses of plays/formations in the United States to estimate global technically recoverable unconventional gas resource. Global technically recoverable unconventional gas resource is estimated from 43,000 (P10) to 112,000 (P90) Tcf.
