Steady State Analysis of Mobile Station State Transition for General Packet Radio Service  

E-Print Network (OSTI)

General Packet Radio Service (GPRS) is a system for efficient data packet radio transmission services which is used in conjunction with the Global System for Mobile Communications (GSM) system. The three mobile station (MS) states idle, ready, and standby are defined for efficient management of radio resources and signaling networks. The MS state transition behavior is modeled and the steady state probability of the MS states is derived using a semi-Markov process approach. The effect of various input parameters on the steady state probability is investigated. These results can be used in analyzing the effect of the input parameters on the tradeoff between location update and paging signaling, and thus, providing guidelines for proper selection of GPRS system parameters.

Wireless Roadside Inspection Phase II Tennessee Commercial Mobile Radio Services Pilot Test Final Report  

SciTech Connect

The Federal Motor Carrier Safety Administration (FMCSA) Wireless Roadside Inspection (WRI) Program is researching the feasibility and value of electronically assessing truck and bus driver and vehicle safety at least 25 times more often than is possible using only roadside physical inspections. The WRI program is evaluating the potential benefits to both the motor carrier industry and to government. These potential benefits include reduction in accidents, fatalities and injuries on our highways and keeping safe and legal drivers and vehicles moving on the highways. WRI Pilot tests were conducted to prototype, test and demonstrate the feasibility and benefits of electronically collecting safety data message sets from in-service commercial vehicles and performing wireless roadside inspections using three different communication methods. This report summarizes the design, conduct and results of the Tennessee CMRS WRI Pilot Test. The purpose of this Pilot test was to demonstrate the implementation of commercial mobile radio services to electronically request and collect safety data message sets from a limited number of commercial vehicles operating in Tennessee. The results of this test have been used in conjunction with the results of the complimentary pilot tests to support an overall assessment of the feasibility and benefits of WRI in enhancing motor carrier safety (reduction in accidents) due to increased compliance (change in motor carrier and driver behavior) caused by conducting frequent safety inspections electronically, at highway speeds, without delay or need to divert into a weigh station

Service Discovery in Multi-radio Networks: An Assessment of Existing Protocols  

E-Print Network (OSTI)

The wide deployment of mobile networks and the emergence of powerful portable devices has given core to pervasive computing. As particularly addressed by Beyond 3G (B3G) networks, the recent evolution of mobile networks introduces the convergence of wireless technologies, where several radio interfaces are to be used concurrently. Thus, B3G-aware applications shall make the most effective use of this connectivity. In pervasive environments, mobile users may discover and access services offered on the networks using Service Discovery Protocols (SDPs). Several SDPs are currently in use, each one designed for specific target network architecture and setting. Thus, in a multi-radio environment, each SDP does not equally suit each radio interface. In order to provide effective service discovery in multi-radio networks, the most resource efficient interface shall be chosen with respect to two main criteria: the adequacy of the radio interface against the SDP to be used, and energy saving, which is crucial for battery-powered devices. Toward this goal, this paper assesses how to exploit multiple radio interfaces from the standpoint of service discovery and access with respect to energy consumption, and the adequacy of the legacy SDPs with the various networks, so as to classify the most appropriate networks for each SDP.

Distributed services for mobile ad hoc networks  

E-Print Network (OSTI)

A mobile ad hoc network consists of certain nodes that communicate only through wireless medium and can move arbitrarily. The key feature of a mobile ad hoc network is the mobility of the nodes. Because of the mobility, communication links form and disappear as nodes come into and go out of each other's communica- tion range. Mobile ad hoc networks are particularly useful in situations like disaster recovery and search, military operations, etc. Research on mobile ad hoc networks has drawn a huge amount of attention recently. The main challenges for mobile ad hoc networks are the sparse resources and frequent mobility. Most of the research work has been focused on the MAC and routing layer. In this work, we focus on distributed services for mobile ad hoc networks. These services will provide some fundamental functions in developing various applications for mobile ad hoc networks. In particular, we focus on the clock synchronization, connected dominating set, and k-mutual exclusion problems in mobile ad hoc networks.

CoolSpots: Reducing the Power Consumption of Wireless Mobile Devices with Multiple Radio Interfaces  

E-Print Network (OSTI)

CoolSpots enable a wireless mobile device to automatically switch between multiple radio interfaces, such as WiFi and Bluetooth, in order to increase battery lifetime. The main contribution of this work is an exploration of the policies that enable a system to switch among these interfaces, each with diverse radio characteristics and different ranges, in order to save power – supported by detailed quantitative measurements. The system and policies do not require any changes to the mobile applications themselves, and changes required to existing infrastructure are minimal. Results are reported for a suite of commonly used applications, such as file transfer, web browsing, and streaming media, across a range of operating conditions. Experimental validation of the CoolSpot system on a mobile research platform shows substantial energy savings: more than a 50 % reduction in energy consumption of the wireless subsystem is possible, with an associated increase in the effective battery lifetime.

Effective Capacity Analysis of Cognitive Radio Channels for Quality of Service Provisioning  

E-Print Network (OSTI)

In this paper, cognitive transmission under quality of service (QoS) constraints is studied. In the cognitive radio channel model, it is assumed that the secondary transmitter sends the data at two different average power levels, depending on the activity of the primary users, which is determined by channel sensing performed by the secondary users. A state-transition model is constructed for this cognitive transmission channel. Statistical limitations on the buffer lengths are imposed to take into account the QoS constraints. The maximum throughput under these statistical QoS constraints is identified by finding the effective capacity of the cognitive radio channel. This analysis is conducted for fixed-power/fixed-rate, fixed-power/variable-rate, and variable-power/variable-rate transmission schemes under different assumptions on the availability of channel side information (CSI) at the transmitter. The impact upon the effective capacity of several system parameters, including channel sensing duration, detect...

Routing Layer Support for Service Discovery in Mobile Ad Hoc Networks  

E-Print Network (OSTI)

Service discovery in Mobile Ad Hoc Networks is an essential process in order for these networks to be selfconfigurable. In this paper we argue that Service Discovery can be greatly enhanced in terms of efficiency (regarding service discoverability and energy consumption), by piggybacking service information in routing layer messages. Thus, a node requesting a service in addition to discovering that service, it is simultaneously informed of the route to the service provider.We extend the Zone Routing Protocol in order to encapsulate service information in its routing messages and through extensive simulations we prove the superiority of our routing layer-enhanced service discovery scheme against an application layer-based flooding scheme.

An energy-efficient middleware for supporting multimedia services in mobile grid environments  

E-Print Network (OSTI)

In this paper, we present techniques for exploiting intermittently available resources in grid infrastructures to support QoS-based multimedia applications on mobile devices. Specifically, we integrate power aware admission control, grid resource discovery, dynamic load-balancing and energy adaptation techniques to enable power deficient devices such as PDAs to run distributed multimedia applications. Our integrated solution adapts to dynamic changes in device energy consumption and unpredictable grid resource availabilities without compromising application Quality of Service (QoS). Our simulation results indicate that our power-aware gridbased approaches, not only improve QoS of mobile multimedia services, but also efficiently load-balance the grid resources.

The cacheand-forward network architecture for efficient mobile content delivery services in the future internet  

E-Print Network (OSTI)

This paper presents a novel “cache-and-forward ” (CNF) protocol architecture for mobile content delivery services in the future Internet. The CNF architecture can be implemented as an overlay on top of the Internet Protocol (IP), or as a clean slate protocol for next-generation networks. CNF is based on the concept of store-and-forward routers with large storage, providing for opportunistic delivery to occasionally disconnected mobile users and for in-network caching of content. The proposed CNF protocol uses reliable hop-by-hop transfer of large data files between CNF routers in place of an end-to-end transport protocol like TCP. This approach makes it possible to serve mobile users with intermittent connectivity, while also mitigating selfinterference problems which arise in multi-hop wireless scenarios. Hop-by-hop transport is similarly useful in wired networks where router storage can help to smooth out link congestion bottlenecks which arise in TCP/IP networks. A second key feature of the CNF protocol is the integration of addressbased and content-based routing to support various content delivery modes that take advantage of in-network storage. An overview of the CNF architecture and major protocol components is given, and preliminary performance evaluation results are summarized to validate the main design principles.

uRbAn: A Multipath Routing based Architecture with Energy and Mobility Management for Quality of Service Support in Mobile Ad hoc Networks  

E-Print Network (OSTI)

Designing a wireless node that supports quality of service (QoS) in a mobile ad hoc network is a challenging task. In this paper, we propose an architecture of a wireless node that may be used to form a mobile ad hoc network that supports QoS. We discuss the core functionalities required for such a node and how those functionalities can be incorporated. A feature of our architecture is that the node has the ability to utilize multiple paths, if available, for the provision of QoS. However, in the absence of multiple paths it can utilize the resources provided by a single path between the source and the destination. We follow a modular approach where each module is expanded iteratively. We compare the features of our architecture with the existing architectures proposed in the literature. Our architecture has provisions of energy and mobility management and it can be customized to design a system-on-chip (SoC).

Denial-of-service attacks on battery-powered mobile computers  

E-Print Network (OSTI)

Sleep deprivation attacks are a form of denial of service attack whereby an attacker renders a pervasive computing device inoperable by draining the battery more quickly than it would be drained under normal usage. We describe three main methods for an attacker to drain the battery: (1) Service request power attacks, where repeated requests are made to the victim for services, typically over a network--even if the service is not provided the victim must expend energy deciding whether or not to honor the request; (2) benign power attacks, where the victim is made to execute a valid but energy-hungry task repeatedly, and (3) malignant power attacks, where the attacker modifies or creates an executable to make the system consume more energy than it would otherwise. Our initial results demonstrate the increased power consumption due to these attacks, which we believe are the first real examples of these attacks to appear in the literature. We also propose a power-secure architecture to thwart these power attacks by employing multi-level authentication and energy signatures. 1.

in print: Mobile Communities – New Business Opportunities for Mobile Network Operators  

E-Print Network (OSTI)

This paper presents the results of an analysis of potential revuenue streams and business models for mobile communities from a mobile network operator’s perspective. It gives a contribution to the answer of the actual business challenges in the mobile carrier sector where operators are continously searching for new innovative services and business models to increase their revenues and financial performance in the age of 3 rd generation mobile technology. Mobile communities are considered to be the next logical evolutional step of the existing virtual communities on the internet. The extension of web-based virtual communities with new community-orientated mobile services is expected to be enormously attractive – from the community user’s point of view as well as from the mobile operators ’ point of view: Mobile operators are playing the central part in terms of realisation and provision of these new services, since they own and build up the necessary technical infrastructure of mobile communication networks. Furthermore, mobile operators are considered to generate direct revenue streams out of mobile community-services, since they bill the connection fees of mobile services. Mobile communities and mobile community services are a very innovative topic. Despite all these great expectations, no empirical experiences have been made yet regarding this topic, since mobile communities are

Mobile systems capability plan  

Science Conference Proceedings (OSTI)

This plan was prepared to initiate contracting for and deployment of these mobile system services. 102,000 cubic meters of retrievable, contact-handled TRU waste are stored at many sites around the country. Also, an estimated 38,000 cubic meters of TRU waste will be generated in the course of waste inventory workoff and continuing DOE operations. All the defense TRU waste is destined for disposal in WIPP near Carlsbad NM. To ship TRU waste there, sites must first certify that the waste meets WIPP waste acceptance criteria. The waste must be characterized, and if not acceptable, subjected to additional processing, including repackaging. Most sites plan to use existing fixed facilities or open new ones between FY1997-2006 to perform these functions; small-quantity sites lack this capability. An alternative to fixed facilities is the use of mobile systems mounted in trailers or skids, and transported to sites. Mobile systems will be used for all characterization and certification at small sites; large sites can also use them. The Carlsbad Area Office plans to pursue a strategy of privatization of mobile system services, since this offers a number of advantages. To indicate the possible magnitude of the costs of deploying mobile systems, preliminary estimates of equipment, maintenance, and operating costs over a 10-year period were prepared and options for purchase, lease, and privatization through fixed-price contracts considered.

Smart Radio Spectrum Management for Cognitive Radio  

E-Print Network (OSTI)

Today's wireless networks are characterized by fixed spectrum assignment policy. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. In this work, a fuzzy logic based system for spectrum management is proposed where the radio can share unused spectrum depending on some parameters like distance, signal strength, node velocity and availability of unused spectrum. The system is simulated and is found to give satisfactory results.

Java-Applet For Radio Spectra Analysis  

E-Print Network (OSTI)

New services for Clusters of Galaxies Database created in the Astronomical Institute of SPbU have been constructed. The detailed description of database and its content is available at http://www.astro.spbu.ru/CLUSTERS/. The information contained in the database can be used for solution of the specific astronomical problems. One of these problems is the researches of radio emission spectra of clusters' objects. The researches can give help in solution of the problems of origin and evolution of extragalactic radio sources. Spectra of radio galaxies contain important information about radio power in the processes responsible for their activity. This report presents the software for the database that provides work with radio spectra of extragalactic sources. This client-application has been released as the Java-applet and thus provides a Web based interface that is supported on many operating systems. The facilities of the applet such as approximations of spectra measurement points and calculation of spectral parameters are illustrated in the report. Also we demonstrate new version of the application that realized on Java2 and gave access to additional functions such as printing.

Are Cluster Radio Relics Revived Fossil Radio Cocoons?  

E-Print Network (OSTI)

A new model for the, so called, `cluster radio relics' is presented (Ensslin & Gopal-Krishna 2000). Fossil radio cocoons, resulting from the former activity of radio galaxies, should contain a low energy relativistic electron population and magnetic fields. Electrons with an age of even up to 2 Gyr can be re-accelerated adiabatically to radio emitting energies, if the fossil radio plasma gets compressed in an environmental shock wave. Such a wave can be caused by a merging event of galaxy clusters, or by the accretion onto galaxy clusters. An implication of this model is the existence of a population of diffuse, ultra-steep spectrum, very low-frequency radio sources located inside and possibly outside of clusters of galaxies, tracing the revival of aged fossil radio plasma by the shock waves associated with large-scale structure formation.

Radio frequency coaxial feedthrough  

DOE Patents (OSTI)

An improved radio frequency coaxial transmission line vacuum feed-through provided based on the use of a half-wavelength annular dielectric pressure barrier disk, or multiple disks comprising an effective half wavelength structure to eliminate reflections from the barrier surfaces. Gas-tight seals are formed about the outer and inner diameter surfaces of the barrier disk using a sealing technique which generates radial forces sufficient to form seals by forcing the conductor walls against the surfaces of the barrier disks in a manner which does not deform the radii of the inner and outer conductors, thereby preventing enhancement of the electric field at the barrier faces which limits voltage and power handling capabilities of a feedthrough.

Power-Aware Communication for Mobile Computers  

E-Print Network (OSTI)

Recently, the mobile community has focused on techniques for reducing energy consumption for mobile hosts. These power management techniques typically target communication devices such as wireless network interfaces, aiming to reduce usage, and thus energy consumption, of the particular device itself. We observe that optimization of a single device's energy consumption, without considering the effect of the strategy on the rest of the machine, can have negative consequences. We propose power management techniques addressing mobile host communications that encompass all components of a mobile host in an effort to optimize total energy consumption. Specifically, we propose runtime adaptation of communication parameters in order to minimize the energy consumed during active data transfer. Information about the network environment is used to drive such adaptations in an effort to compensate for the effect of dynamic service from wireless communication device on the energy consume...

Radio frequency communication system utilizing radiating transmission lines  

DOE Patents (OSTI)

A radio communication system for use in tunnels, mines, buildings or other shielded locations in which a pair of radiating transmission lines (30), (31) extend through such location in spaced coextensive relation to each other. Each transmission line (30), (31) has at least one unidirectional amplifier (32), (33) interposed therein with the sense of the unidirectional amplifier (32) of one transmission line (30) being opposite to the sense of the unidirectional amplifier (33) of the other transmission line (31). Each of the amplifiers (32), (33) has a gain which is less than the coupling loss between the transmission lines (30), (31). Two or more mobile transceivers (35) in the location served by the system are coupled to the transmission lines (30), (31) by electromagnetic wave propagation in space in order to communicate directly with each other at a given radio frequency within the frequency range of the system.

Comparison between Poissonian and Markovian Primary Traffics in Cognitive Radio Networks  

E-Print Network (OSTI)

Cognitive Radio generates a big interest as a key cost-effective solution for the underutilization of frequency spectrum in legacy communication networks. The objective of this work lies in conducting a performance evaluation of the end-to-end message delivery under both Markovian and Poissonian primary traffics in lossy Cognitive Radio networks. We aim at inferring the most appropriate conditions for an efficient secondary service provision according to the Cognitive Radio network characteristics. Meanwhile, we have performed a general analysis for many still open issues in Cognitive Radio, but at the end only two critical aspects have been considered, namely, the unforeseen primary reclaims in addition to the collided cognitive transmissions due to the Opportunistic Spectrum Sharing. Some graphs, in view of the average Spectral Efficiency, have been computed and plotted to report some comparative results for a given video transmission under the Markovian and the Poissonian primary interruptions.

GALAXY CLUSTER ENVIRONMENTS OF RADIO SOURCES  

SciTech Connect

Using the Sloan Digital Sky Survey (SDSS) and the Faint Images of the Radio Sky at Twenty Centimeters (FIRST) catalogs, we examined the optical environments around double-lobed radio sources. Previous studies have shown that multi-component radio sources exhibiting some degree of bending between components are likely to be found in galaxy clusters. Often this radio emission is associated with a cD-type galaxy at the center of a cluster. We cross-correlated the SDSS and FIRST catalogs and measured the richness of the cluster environments surrounding both bent and straight multi-component radio sources. This led to the discovery and classification of a large number of galaxy clusters out to a redshift of z {approx} 0.5. We divided our sample into smaller subgroups based on their optical and radio properties. We find that FR I radio sources are more likely to be found in galaxy clusters than FR II sources. Further, we find that bent radio sources are more often found in galaxy clusters than non-bent radio sources. We also examined the environments around single-component radio sources and find that single-component radio sources are less likely to be associated with galaxy clusters than extended, multi-component radio sources. Bent, visually selected sources are found in clusters or rich groups {approx}78% of the time. Those without optical hosts in SDSS are likely associated with clusters at even higher redshifts, most with redshifts of z>0.7.

An Experiment Study of the Propagation of Radio Waves in a Scaled Model of Long-Wall Coal Mining Tunnels  

SciTech Connect

A long-wall coal mining tunnel is the most important working area in a coal mine. It has long been realized that radio communications can improve both productivity and safety in this dangerous area. Hence, many attempts to use radio communications in such an environment have been made. Unfortunately, no radio system has satisfactorily provided communication services there, which, we believe, is partially due to poor understanding of the propagation characteristics of radio waves in the long-wall mining tunnel. To have deeper physical insight into the propagation problem, a scaled model of the long-wall mining tunnel was built, and the propagation characteristics of UHF radio waves were measured. The experiment and the measured results are presented and discussed.

Radio astronomical imaging in the presence of strong radio interference  

E-Print Network (OSTI)

Abstract—Radio-astronomical observations are increasingly contaminated by interference, and suppression techniques become essential. A powerful candidate for interference mitigation is adaptive spatial filtering. We study the effect of spatial filtering techniques on radio-astronomical imaging. Current deconvolution procedures, such as CLEAN, are shown to be unsuitable for spatially filtered data, and the necessary corrections are derived. To that end, we reformulate the imaging (deconvolution/calibration) process as a sequential estimation of the locations of astronomical sources. This not only leads to an extended CLEAN algorithm, but also the formulation allows the insertion of other array signal processing techniques for direction finding and gives estimates of the expected image quality and the amount of interference suppression that can be achieved. Finally, a maximum-likelihood (ML) procedure for the imaging is derived, and an approximate ML image formation technique is proposed to overcome the computational burden involved. Some of the effects of the new algorithms are shown in simulated images. Index Terms—CLEAN, interference mitigation, maximum likelihood, minimum variance, parametric imaging, radio astronomy, spatial filtering, synthesis imaging. I.

Object localization strategy for a mobile robot using RFID  

E-Print Network (OSTI)

One of the challenging issues in robotics is to give robots the ability to navigate itself in unknown environment without human help. In this thesis, we explored and evaluated object localization method for a mobile robot using radio-frequency identification (RFID) technology. The workplace included objects with RFID tags, a mobile robot with dual antenna RFID reader and obstacles: chairs, tables and a human. Using RFID reader, we were able to have the mobile robot communicate with the RFID tag to navigate the tagged object. This research employed the following methods for navigating a mobile robot and locating objects. First, a mobile robot was implemented as Braitenberg vehicle. It used the received signal strength of the RFID tag to compute instantaneously and produce movement of the wheel and generate suitable motion in order to navigate the object. Second, a mobile robot with directional antenna that collects data about relative direction of the interested RFID tag in its local coordinate system and computes tag positions by taking several measurements for different positions of the robot. Our experiment results showed that proposed RFID system can locate an object and can track the movement of a target object in real time. To verify effectiveness of the system we performed several experiments in the workplace.

Cloud Based Application Development for Accessing Restaurant Information on Mobile Device using LBS  

E-Print Network (OSTI)

Over the past couple of years, the extent of the services provided on the mobile devices has increased rapidly. A special class of service among them is the Location Based Service(LBS) which depends on the geographical position of the user to provide services to the end users. However, a mobile device is still resource constrained, and some applications usually demand more resources than a mobile device can a ord. To alleviate this, a mobile device should get resources from an external source. One of such sources is cloud computing platforms. We can predict that the mobile area will take on a boom with the advent of this new concept. The aim of this paper is to exchange messages between user and location service provider in mobile device accessing the cloud by minimizing cost, data storage and processing power. Our main goal is to provide dynamic location-based service and increase the information retrieve accuracy especially on the limited mobile screen by accessing cloud application. In this paper we presen...

The Triggering and Bias of Radio Galaxies  

E-Print Network (OSTI)

We present new results on the clustering and three-dimensional distribution of radio galaxies from the Texas-Oxford NVSS Structure (TONS) survey. The TONS survey was constructed to look at the distribution of radio galaxies in a region of moderate (0 3 mJy) radio galaxies over large areas on the sky. We find that redshift spikes, which represent large concentrations of radio galaxies which trace (~ 100 Mpc^3) super-structures are a common phenomena in these surveys. Under the assumption of quasi-linear structure formation theory and a canonical radio galaxy bias, the structures represent ~ 4-5 sigma peaks in the primordial density field and their expected number is low. The most plausible explanation for these low probabilities is an increase in the radio galaxy bias with redshift. To investigate potential mechanisms which have triggered the radio activity in these galaxies - and hence may account for an increase in the bias of this population, we performed imaging studies of the cluster environment of the radio galaxies in super-structure regions. Preliminary results show that these radio galaxies may reside preferentially at the edges of rich clusters. If radio galaxies are preferentially triggered as they fall towards rich clusters then they would effectively adopt the cluster bias.

Robotic localization of hostile networked radio sources with a directional antenna  

E-Print Network (OSTI)

One of the distinguishing characteristics of hostile networked radio sources (e.g., enemy sensor network nodes), is that only physical layer information and limited medium access control (MAC) layer information of the network is observable. We propose a scheme to localize hostile networked radio sources based on the radio signal strength and communication protocol pattern analysis using a mobile robot with a directional antenna. We integrate a Particle Filter algorithm with a new sensing model which is built on a directional antenna model and Carrier Sense Multiple Access (CSMA)-based MAC protocol model. we model and analyze the channel idle probability and busy collision probability as a function of the number of radio sources in the CSMA protocol modeling. Based on the sensing model, we propose a particle-filter-based scheme to simultaneously estimate the number and the positions of networked radio sources. We provide a localization scheme based on the method of steepest descent for the purpose of performance comparison. Simulation results demonstrate that our proposed localization scheme has a better success rate than the scheme based on the steepest descent at different tolerant distances.

We have obtained multi-colour imaging of a representative, statistically complete sample of low-frequency selected (S_408MHz > 0.95Jy) radio loud quasars at intermediate (0.6 environmental richness, based upon single-band observations are inadequate at these redshifts for a variety of reasons. Environmental richness seems correlated with the size and morphology of the radio source, as expected if the energy density in the radio lobes is approximately the equipartition value and the lobes are in pressure equilbrium with a surrounding intragroup/cluster medium. Selecting on radio size therefore efficiently selects dense galactic sytems at these redshifts.

We define a practical taxonomy of user interface components for such systems and establish methodology for adaptive mobile augmented reality interfaces that dynamically rearrange themselves in response to changes in user context. The research contributions to the state-of-the-art in augmented reality begin with the author’s participation in the design of the ”Columbia Touring Machine ” in 1997, the first example of an outdoor mobile augmented reality system, and his lead in developing later prototypes. We develop a series of hardware and software infrastructures for prototyping mobile augmented reality applications that allow multiple users to participate in collaborative tasks taking place indoors and outdoors. We present exploratory user interfaces for many different applications and user scenarios, including the Situated Documentaries application framework for experiencing spatially distributed hypermedia presentations.

New radio observations of QSO 0957+561 confirm optical-to radio time delay  

E-Print Network (OSTI)

In our previous publications have been reported about possible time delay between optical and radio (6 cm) variations in QSO 0957+561 and noted that the result can be tested with new radio observations. Here we have made this test using new published (Haarasma et al., 1999) radio observations of the object in 6 cm and 4 cm. We have found that the new observations confirm optical-to-radio time delay. Additionally we have found that radio 6 cm variations followed 4 cm ones with time delay about 230 days. Obtained results imply existence of the variable beamed hard radiation in the nucleus of the QSO.

A radio frequency coaxial feedthrough  

DOE Patents (OSTI)

An improved radio frequency coaxial transmission line vacuum feedthrough is provided based on the use of a half-wavelength annular dielectric pressure barrier disk, or multiple disks comprising an effective half wavelength structure to eliminate reflection from the barrier surfaces. Gas-tight seals are formed about the outer and inner diameter surfaces of the barrier disk using a sealing technique which generates radial forces sufficient to form seals by forcing the conductor walls against the surfaces of the barrier disks in a manner which does not deform the radii of the inner and outer conductors, thereby preventing enhancement of the electric field at the barrier faces which limits the voltage and power handling capabilities of a feedthrough.

DIFFUSIVE SHOCK ACCELERATION SIMULATIONS OF RADIO RELICS  

Science Conference Proceedings (OSTI)

Recent radio observations have identified a class of structures, so-called radio relics, in clusters of galaxies. The radio emission from these sources is interpreted as synchrotron radiation from GeV electrons gyrating in {mu}G-level magnetic fields. Radio relics, located mostly in the outskirts of clusters, seem to associate with shock waves, especially those developed during mergers. In fact, they seem to be good structures to identify and probe such shocks in intracluster media (ICMs), provided we understand the electron acceleration and re-acceleration at those shocks. In this paper, we describe time-dependent simulations for diffusive shock acceleration at weak shocks that are expected to be found in ICMs. Freshly injected as well as pre-existing populations of cosmic-ray (CR) electrons are considered, and energy losses via synchrotron and inverse Compton are included. We then compare the synchrotron flux and spectral distributions estimated from the simulations with those in two well-observed radio relics in CIZA J2242.8+5301 and ZwCl0008.8+5215. Considering that CR electron injection is expected to be rather inefficient at weak shocks with Mach number M {approx}< a few, the existence of radio relics could indicate the pre-existing population of low-energy CR electrons in ICMs. The implication of our results on the merger shock scenario of radio relics is discussed.

Mobile Biomass Pelletizing System  

DOE Green Energy (OSTI)

This grant project examines multiple aspects of the pelletizing process to determine the feasibility of pelletizing biomass using a mobile form factor system. These aspects are: the automatic adjustment of the die height in a rotary-style pellet mill, the construction of the die head to allow the use of ceramic materials for extreme wear, integrating a heat exchanger network into the entire process from drying to cooling, the use of superheated steam for adjusting the moisture content to optimum, the economics of using diesel power to operate the system; a break-even analysis of estimated fixed operating costs vs. tons per hour capacity. Initial development work has created a viable mechanical model. The overall analysis of this model suggests that pelletizing can be economically done using a mobile platform.

Radio frequency sustained ion energy  

SciTech Connect

Electromagnetic (E.M.) energy injection method and apparatus for producing and sustaining suprathermal ordered ions in a neutral, two-ion-species, toroidal, bulk equilibrium plasma. More particularly, the ions are produced and sustained in an ordered suprathermal state of existence above the average energy and velocity of the bulk equilibrium plasma by resonant rf energy injection in resonance with the natural frequency of one of the ion species. In one embodiment, the electromagnetic energy is injected to clamp the energy and velocity of one of the ion species so that the ion energy is increased, sustained, prolonged and continued in a suprathermal ordered state of existence containing appreciable stored energy that counteracts the slowing down effects of the bulk equilibrium plasma drag. Thus, selective deuteron absorption may be used for ion-tail creation by radio-frequency excitation alone. Also, the rf can be used to increase the fusion output of a two-component neutral injected plasma by selective heating of the injected deuterons.

Kinetically Dominated FRII Radio Sources  

E-Print Network (OSTI)

The existence of FR II objects that are kinetically dominated, the jet kinetic luminosity, $Q$, is larger than the total thermal luminosity (IR to X-ray) of the accretion flow, $L_{bol}$, is of profound theoretical interest. Such objects are not expected in most theoretical models of the central engine of radio loud AGN. Thus, establishing such a class of objects is an important diagnostic for filtering through the myriad of theoretical possibilities. This paper attempts to establish a class of quasars that have existed in a state of kinetic dominance, $R(t)\\equiv Q(t)/L_{bol}(t)>1$, at some epoch, $t$. It is argued that the 10 quasars in this article with a long term time average $Q(t)$, $\\bar{Q}$, that exceed $L_{Edd}$ are likely to have satisfied the condition $R(t)>1$ either presently or in the past based on the rarity of $L_{bol}>L_{Edd}$ quasars. Finally, the existence of these sources is discussed in the context of the theory of the central engine.

Landmark routing in ad hoc networks with mobile backbones  

E-Print Network (OSTI)

A Mobile Ad Hoc Network (MANET) is usually assumed to be homogeneous, where each mobile node shares the same radio capacity. However, a homogeneous ad hoc network suffers from poor scalability. Recent research has demonstrated its performance bottleneck through both theoretical analysis and simulation experiments and testbed measurements. This is further exacerbated by heavy routing overhead of ad hoc routing protocols when the network size is large. In this paper, we present a design methodology to build a hierarchical large-scale ad hoc network using different types of radio capabilities at different layers. In such a structure, nodes are first dynamically grouped into multi-hop clusters. Each group elects a cluster-head to be a backbone node (BN). Then higher-level links are established to connect the BNs into a backbone network. Following this method recursively, a multilevel hierarchical network can be established. Three critical issues are addressed in this paper. We first analyze the optimal number of BNs for a layer in theory. Then, we propose a stable and light overhead clustering scheme to deploy the BNs. Finally LANMAR routing is extended to operate the physical hierarchy efficiently. We show that the Hierarchical LANMAR (H-LANMAR) can incorporate and efficiently utilize backbone links to reach remote destinations (thus reducing the hop distance). Simulation results using GloMoSim confirm that our proposed schemes achieve good performance.

Superconducting radio-frequency modules test faciilty operating experience  

Science Conference Proceedings (OSTI)

Fermilab is heavily engaged and making strong technical contributions to the superconducting radio-frequency research and development program (SRF R&D). Four major SRF test areas are being constructed to enable vertical and horizontal cavity testing, as well as cryomodule testing. The existing Fermilab cryogenic infrastructure has been modified to service Fermilab SRF R&D needs. The first stage of the project has been successfully completed, which allows for distribution of cryogens for a single cavity cryomodule using the existing Cryogenic Test Facility (CTF) that houses three Tevatron satellite refrigerators. The cooling capacity available for cryomodule testing at MDB results from the liquefaction capacity of the CTF cryogenic system. The cryogenic system for a single 9-cell cryomodule is currently operational. The paper describes the status, challenges and operational experience of the initial phase of the project.

The authors would also like to thank Roy Welsch and Frank Harrell for their help in statistical interpretation. Contact Stuart Madnick for access to the contest data. Mobilization across social networks is becoming increasingly influential, but little is known about what traits of individuals and their relationships affect their speed of mobilization between them. We ran a global social mobilization contest and recorded personal traits of the participants and those they mobilized. We examined how those traits influenced the speed of mobilization. Individuals mobilized faster when they heard about the contest directly from the contest organization, and decreased in speed when hearing from less personal source types (e.g. family vs. media). Mobilization was faster when the mobilizer and

Mobile Window Thermal Test  

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

Mobile Window Thermal Test (MoWiTT) Facility Mobile Window Thermal Test (MoWiTT) Facility winter.jpg (469135 bytes) The window has come a long way since the days when it was a single pane of glass in a wood frame. Low-emissivity windows were designed to help buildings retain some of the energy that would have leaked out of less efficient windows. Designing efficient window-and-frame systems is one strategy for reducing the energy use of buildings. But the net energy flowing through a window is a combination of temperature- driven thermal flows and transmission of incident solar energy, both of which vary with time. U-factor and solar heat gain coefficient (SHGC), the window properties that control these flows, depend partly on ambient conditions. Window energy flows can affect how much energy a building uses, depending on when the window flows are available to help meet other energy demands within the building, and when they are adverse, adding to building energy use. This leads to a second strategy for reducing building energy use: using the beneficial solar gain available through a window, either for winter heating or for daylighting, while minimizing adverse flows.

Interplanetary shocks lacking type II radio bursts  

E-Print Network (OSTI)

We report on the radio-emission characteristics of 222 interplanetary (IP) shocks. A surprisingly large fraction of the IP shocks (~34%) is radio quiet (i.e., the shocks lacked type II radio bursts). The CMEs associated with the RQ shocks are generally slow (average speed ~535 km/s) and only ~40% of the CMEs were halos. The corresponding numbers for CMEs associated with radio loud (RL) shocks are 1237 km/s and 72%, respectively. The RQ shocks are also accompanied by lower peak soft X-ray flux. CMEs associated with RQ (RL) shocks are generally accelerating (decelerating). The kinematics of CMEs associated with the km type II bursts is similar to those of RQ shocks, except that the former are slightly more energetic. Comparison of the shock The RQ shocks seem to be mostly subcritical and quasi-perpendicular. The radio-quietness is predominant in the rise phase and decreases through the maximum and declining phases of solar cycle 23. The solar sources of the shock-driving CMEs follow the sunspot butterfly diagra...

Juvenile Radio-Tag Study: Lower Granite Dam, 1985 Annual Report.  

DOE Green Energy (OSTI)

The concept of using mass releases of juvenile radio tags represents a new and potentially powerful research tool that could be effectively applied to juvenile salmonid passage problems at dams on the Columbia and Snake Rivers. A system of detector antennas, strategically located, would automatically detect and record individually tagged juvenile salmonids as they pass through the spillway, powerhouse, bypass system, or tailrace areas below the dam. Accurate measurements of spill effectiveness, fish guiding efficiency (FGE), collection efficiency (CE), spillway survival, powerhouse survival, and bypass survival would be possible without handling large numbers of unmarked fish. A prototype juvenile radio-tag system was developed and tested by the National Marine Fisheries Service (NMFS) and Bonneville Power Administration (BPA) at John Day Dam and at Lower Granite Dam. This report summarizes research to: (1) evaluate the effectiveness of the prototype juvenile radio-tag system in a field situation and (2) to test the basic assumptions inherent in using the juvenile radio tag as a research tool.

Detecting energy-greedy anomalies and mobile malware variants  

E-Print Network (OSTI)

Mobile users of computation and communication services have been rapidly adopting battery-powered mobile handhelds, such as PocketPCs and SmartPhones, for their work. However, the limited battery-lifetime of these devices restricts their portability and applicability, and this weakness can be exacerbated by mobile malware targeting depletion of battery energy. Such malware are usually difficult to detect and prevent, and frequent outbreaks of new malware variants also reduce the effectiveness of commonlyseen signature-based detection. To alleviate these problems, we propose a power-aware malware-detection framework that monitors, detects, and analyzes previously unknown energy-depletion threats. The framework is composed of (1) a power monitor which collects power samples and builds a power consumption history from the collected samples, and (2) a data analyzer which generates a power signature from the constructed history. To generate a power signature, simple and effective noise-filtering and data-compression are applied, thus reducing the detection overhead. Similarities between power signatures are measured by the ? 2-distance, reducing both false-positive and false-negative detection rates. According to our experimental results on an HP iPAQ running a Windows Mobile OS, the proposed framework achieves significant (up to 95%) storage-savings without losing the detection accuracy, and a 99 % true-positive rate in classifying mobile malware.

Juvenile Radio-Tag Study: Lower Granite Dam, 1985-1986 Final Report.  

DOE Green Energy (OSTI)

A prototype juvenile radio-tag system was developed and tested by the National Marine Fisheries Services (NMFS) and Bonneville Power Administration (BPA) at John Day Dam in 1984. Results indicated that the system could provide acceptable estimates of powerhouse and spillway passage. Research in 1986 continued testing of the tag system to further define its application and limitations. Field work included releases in the forebay and tailrace under a no-spill environment and testing of new systems to improve tag detection. Laboratory tests included the response of the tag in hostile environmental conditions (spillway passage) and the effects of the radio tag on fish buoyancy compensation. This report provides results of the work along with a summarization of the combined 1985--86 field and assumption testing. 12 refs., 10 figs., 8 tabs.

Large Radio Astronomy: next 70 Years Step  

E-Print Network (OSTI)

Some attempts to predict the very distant future of Radio Astronomy are given. It is not easy to predict a list of the first priority problems which may appear, but the facilities potential is more predictable. It is suggested, that in addition to the "dedicated for Radio Astronomy", facilities may be extended greatly by integration with the next generation living standards facilities, connected with People-to-People communications through the global networks and by incorporating of the "Natural facilities", such as grav. lensing, maser amplification in the ISM etc. As an examples of the extreme cases of the $10^9 m^2$ class of the new generation Radio Telescopes, utilization of the personal dipole size communication facilities by SKA type instrument, and array from the asteroids first "Frehnel zones" will be mentioned. Radio Astronomy from the secondary to optical facilities tool will be the only tool in the exploration of the $z>10$ Universe. The reality of all predictions depend mostly on the way, the Civilization will prefer : "Ahead, to HOMO SAPIENCE" or "BACK TO PRIMATES".

Molecular gas in nearby elliptical radio galaxies  

E-Print Network (OSTI)

Powerful radio-AGN are hosted by massive elliptical galaxies which are usually very poor in molecular gas. Nevertheless the central Black Hole (BH) needs molecular gas for the nuclear activity. Thus it is important to study the origin, the distribution and the kinematics of the molecular gas in such objects. We have performed at the IRAM-30m telescope a survey of the CO(1-0) and CO(2-1) emission in the most powerful radio galaxies of the Local Universe, selected only on the basis of their radio continuum fluxes. The main result of that survey is the low content in molecular gas of such galaxies compared to Seyfert galaxies. The median value of the molecular gas mass is 4x10^8 Msun. Moreover, the CO spectra indicate the presence of a central molecular gas disk in some of these radio galaxies. We complemented this survey with photometric data of SPITZER and IRAS fluxes with the purpose to study the dust and its relation with the molecular gas and AGN.

Integrated mobile GIS and wireless internet map servers for environmental monitoring and management  

E-Print Network (OSTI)

ABSTRACT: With the progress of mobile GIS technology there is a great potential for adopting wireless communications and Internet mapping services for regional environmental management programs and natural habitat conservation. This paper provides an overview of a NASA-funded research project that focuses on the development of mobile GIS tools and wireless Internet Map Server (IMS) services to facilitate environmental monitoring and management tasks. By developing and testing wireless web-based map/image servers, mobile GIS applications, and global positional systems (GPS), this research created an integrated software/hardware infrastructure for a prototype mobile GIS application. The mobile GIS prototype allows multiple resource managers and park rangers to access large-size, remotely sensed images and GIS layers from a portable web server mounted in a vehicle. Users can conduct real-time spatial data updates and/or submit changes back to the web server over the wireless local area network (WLAN). This paper discusses in general the major components of mobile GIS, their current technological limitations, and potential problems during implementation. Key research agenda for mobile GIS are identified with suggestions for future research and development.

Mobile Energy Laboratory Procedures  

SciTech Connect

Pacific Northwest Laboratory (PNL) has been tasked to plan and implement a framework for measuring and analyzing the efficiency of on-site energy conversion, distribution, and end-use application on federal facilities as part of its overall technical support to the US Department of Energy (DOE) Federal Energy Management Program (FEMP). The Mobile Energy Laboratory (MEL) Procedures establish guidelines for specific activities performed by PNL staff. PNL provided sophisticated energy monitoring, auditing, and analysis equipment for on-site evaluation of energy use efficiency. Specially trained engineers and technicians were provided to conduct tests in a safe and efficient manner with the assistance of host facility staff and contractors. Reports were produced to describe test procedures, results, and suggested courses of action. These reports may be used to justify changes in operating procedures, maintenance efforts, system designs, or energy-using equipment. The MEL capabilities can subsequently be used to assess the results of energy conservation projects. These procedures recognize the need for centralized NM administration, test procedure development, operator training, and technical oversight. This need is evidenced by increasing requests fbr MEL use and the economies available by having trained, full-time MEL operators and near continuous MEL operation. DOE will assign new equipment and upgrade existing equipment as new capabilities are developed. The equipment and trained technicians will be made available to federal agencies that provide funding for the direct costs associated with MEL use.

Bacterial mobilization of polonium  

Science Conference Proceedings (OSTI)

Polonium has been observed as the sole {alpha}-emitting nuclide in groundwaters of central Florida, in the absence of its radiogenic parents, at levels of 1,000 dpm/1 or more. Because of the chemical similarity of Po to S (both occupy the same column in the periodic table), studies were begun to determine whether bacteria, particularly those species active in sulfur cycling, could account for the selective solubilization and mobilization of Po. Possible sources of Po are the U-rich phosphate rock and phosphogypsum (gypsum), a byproduct in the manufacture of phosphoric acid. This paper reports on a series of experiments involving the interaction of bacteria with this waste gypsum that resulted in the solubilization of Po. Bacteria were isolated from gypsum that were capable of mediating Po release in column experiments of Po. Bacteria were isolated from gypsum that were capable of mediating Po release in column experiments when fed a growth medium. Sulfate-reducing bacteria were particularly effective at mediating Po release provided the sulfide levels did not rise above 10 {mu}M, in which case Po was apparently coprecipitated as a metal sulfide. Conversely, the ability of sulfate-reducing bacteria to effectively remove dissolved Po when sulfide levels are high suggests that these bacteria may be used as an effective bioremediation tool at reducing groundwater Po levels. 22 refs., 10 figs.

Cosmological Parameters and Quintessence From Radio Galaxies  

E-Print Network (OSTI)

FRIIb radio galaxies provide a tool to determine the coordinate distance to sources at redshifts from zero to two. The coordinate distance depends on the present values of global cosmological parameters, quintessence, and the equation of state of quintessence. The coordinate distance provides one of the cleanest determinations of global cosmological parameters because it does not depend on the clustering properties of any of the mass-energy components present in the universe. Two complementary methods that provide direct determinations of the coordinate distance to sources with redshifts out to one or two are the modified standard yardstick method utilizing FRIIb radio galaxies, and the modified standard candle method utilizing type Ia supernovae. These two methods are compared here, and are found to be complementary in many ways. The two methods do differ in some regards; perhaps the most significant difference is that the radio galaxy method is completely independent of the local distance scale and independent of the properties of local sources, while the supernovae method is very closely tied to the local distance scale and the properties of local sources. FRIIb radio galaxies provide one of the very few reliable probes of the coordinate distance to sources with redshifts out to two. This method indicates that the current value of the density parameter in non-relativistic matter, ?m, must be low, irrespective of whether the universe is spatially flat, and of whether a significant cosmological constant or quintessence pervades the universe at the present epoch. The effect of quintessence, with equation of state w, is considered. FRIIb radio galaxies indicate that the universe is currently accelerating in its expansion if the primary components of the universe at the present epoch are non-relativistic matter and quintessence, and the universe is spatially flat. 1.

The large scale clustering of radio sources  

E-Print Network (OSTI)

The observed two-point angular correlation function, w(theta), of mJy radio sources exhibits the puzzling feature of a power-law behaviour up to very large (almost 10 degrees) angular scales which cannot be accounted for in the standard hierarchical clustering scenario for any realistic redshift distribution of such sources. After having discarded the possibility that the signal can be explained by a high density local source population, we find no alternatives to assuming that - at variance with all the other extragalactic populations studied so far, and in particular with optically selected quasars - radio sources responsible for the large-scale clustering signal were increasingly less clustered with increasing look-back time, up to at least z=1. The data are accurately accounted for in terms of a bias function which decreases with increasing redshift, mirroring the evolution with cosmic time of the characteristic halo mass, M_{star}, entering the non linear regime. In the framework of the `concordance cosmology', the effective halo mass controlling the bias parameter is found to decrease from about 10^{15} M_{sun}/h at z=0 to the value appropriate for optically selected quasars, 10^{13} M_{sun}/h, at z=1.5. This suggests that, in the redshift range probed by the data, the clustering evolution of radio sources is ruled by the growth of large-scale structure, and that they are associated with the densest environments virializing at any cosmic epoch. The data provide only loose constraints on radio source clustering at z>1 so we cannot rule out the possibility that at these redshifts the clustering evolution of radio sources enters a different regime, perhaps similar to that found for optically selected quasars. The dependence of w(theta) on cosmological parameters is also discussed.

AEGIS20: a radio survey of the Extended Groth Strip  

E-Print Network (OSTI)

We describe AEGIS20 - a radio survey of the Extended Groth Strip (EGS) conducted with the Very Large Array (VLA) at 1.4GHz. The resulting catalog contains 1,123 emitters and is sensitive to ultraluminous starbursts to z1 where correcting for contamination by radio-loud active galactic nuclei (AGN) comes at the price of rejecting luminous starbursts. Whilst stacking radio images is a useful technique, accurate radio-based SFRs for z>>1 galaxies require precise redshifts and extraordinarily high-fidelity radio data to identify and remove accretion-related emission.

Security Schemes for Wireless Sensor Networks with Mobile Sink  

E-Print Network (OSTI)

Mobile sinks are vital in many wireless sensor applications for efficient data collection, data querying, and localized sensor reprogramming. Mobile sinks prolong the lifetime of a sensor network. However, when sensor networks with mobile sinks are deployed in a hostile environment, security became a critical issue. They become exposed to varieties of malicious attacks. Thus, anti threats schemes and security services, such as mobile sink?s authentication and pairwise key establishment, are essential components for the secure operation of such networks. Due to the sensors, limited resources designing efficient security schemes with low communication overhead to secure communication links between sensors and MS (Mobile Sink) is not a trivial task. In addition to the sensors limited resources, sink mobility required frequent exchange of cryptography information between the sensors and MS each time the MS updates its location which imposes extra communication overhead on the sensors. In this dissertation, we consider a number of security schemes for WSN (wireless sensor network) with MS. The schemes offer high network?s resiliency and low communication overhead against nodes capture, MS replication and wormhole attacks. We propose two schemes based on the polynomial pool scheme for tolerating nodes capture: the probabilistic generation key pre-distribution scheme combined with polynomial pool scheme, and the Q-composite generation key scheme combined with polynomial pool scheme. The schemes ensure low communication overhead and high resiliency. For anti MS replication attack scheme, we propose the multiple polynomial pools scheme that provide much higher resiliency to MS replication attack as compared to the single polynomial pool approach. Furthermore, to improve the network resiliency against wormhole attack, two defensive mechanisms were developed according to the MS mobility type. In the first technique, MS uses controlled mobility. We investigate the problem of using a single authentication code by sensors network to verify the source of MS beacons, and then we develop a defensive approach that divide the sensor network into different authentication code?s grids. In the second technique, random mobility is used by MS. We explore the use of different communication channels available in the sensor hardware combined with polynomial pool scheme.

Vectorial Radio Interferometry with LOPES 3D  

E-Print Network (OSTI)

One successful detection technique for high-energy cosmic rays is based on the radio signal emitted by the charged particles in an air shower. The LOPES experiment at Karlsruhe Institute of Technology, Germany, has made major contributions to the evolution of this technique. LOPES was reconfigured several times to improve and further develop the radio detection technique. In the latest setup LOPES consisted of 10 tripole antennas. With this, LOPES 3D was the first cosmic ray experiment measuring all three vectorial field components at once and thereby gaining the full information about the electric field vector. We present an analysis based on the data taken with special focus on the benefits of a direct measurement of the vertical polarization component. We demonstrate that by measuring all polarization components the detection and reconstruction efficiency is increased and noisy single channel data can be reconstructed by utilising the information from the other two channels of one antenna station.

A dichotomy in radio jet orientations  

E-Print Network (OSTI)

We examine the relative orientations of radio jets, central dust and stars in low-power (i.e., FR I and FR I/II) radio galaxies. We use the position angles of jet and dust to constrain the three-dimensional angle $\\theta_{\\rm DJ}$ between jet and dust. For galaxies with filamentary dust 'lanes' (which tend to be misaligned with the galaxy major axis) the jet is approximately perpendicular to the dust structure, while for galaxies with elliptical dust distributions (typically aligned with the galaxy major axis) there is a much wider distribution of $\\theta_{\\rm DJ}$. nThe dust ellipses are consistent with being nearly circular thin disks viewed at random viewing angles. The lanes are likely warped, unsettled dust structures. We consider two scenarios to explain the dust/jet orientation dichotomy.

Watson Keywords technologies Abstract Various wireless technologies were field-tested in a six-story laboratory building to identify wireless technologies that can scale for future DR applications through very low node density power consumption, and unit cost. Data analysis included analysis of the signal-to-noise ratio (SNR), packet loss, and link quality at varying power levels and node densities. The narrowband technologies performed well, penetrating the floors of the building with little loss and exhibiting better range than the wideband technology. 900 MHz provided full coverage at 1 watt and substantially complete coverage at 500 mW at the test site. 900 MHz was able to provide full coverage at 100 mW with only one additional relay transmitter, and was the highest-performing technology in the study. 2.4 GHz could not provide full coverage with only a single transmitter at the highest power level tested (63 mW). However, substantially complete coverage was provided at 2.4 GHz at 63 mW with the addition of one repeater node.

The hydrodynamics of dead radio galaxies  

E-Print Network (OSTI)

We present a numerical investigation of dead, or relic, radio galaxies and the environmental impact that radio galaxy activity has on the host galaxy or galaxy cluster. We perform axisymmetric hydrodynamical calculations of light, supersonic, back-to-back jets propagating in a beta-model galaxy/cluster atmosphere. We then shut down the jet activity and let the resulting structure evolve passively. The dead source undergoes an initial phase of pressure driven expansion until it achieves pressure equilibrium with its surroundings. Thereafter, buoyancy forces drive the evolution and lead to the formation of two oppositely directed plumes that float high into the galaxy/cluster atmosphere. These plumes entrain a significant amount of low entropy material from the galaxy/cluster core and lift it high into the atmosphere. An important result is that a large fraction (at least half) of the energy injected by the jet activity is thermalized in the ISM/ICM core. The whole ISM/ICM atmosphere inflates in order to regain hydrostatic equilibrium. This inflation is mediated by an approximately spherical disturbance which propagates into the atmosphere at the sound speed. The fact that such a large fraction of the injected energy is thermalized suggests that radio galaxies may have an important role in the overall energy budget of rich ISM/ICM atmospheres. In particular, they may act as a strong and highly time-dependent source of negative feedback for galaxy/cluster cooling flows.

Sketch Recognition on Mobile Devices  

E-Print Network (OSTI)

Sketch recognition allows computers to understand and model hand drawn sketches and diagrams. Traditionally sketch recognition systems required a pen based PC interface, but powerful mobile devices such as tablets and smartphones can provide a new platform for sketch recognition systems. We describe a new sketch recognition library, Strontium (SrL) that combines several existing sketch recognition libraries modified to run on both personal computers and on the Android platform. We analyzed the recognition speed and accuracy implications of performing low-level shape recognition on smartphones with touch screens. We found that there is a large gap in recognition speed on mobile devices between recognizing simple shapes and more complex ones, suggesting that mobile sketch interface designers limit the complexity of their sketch domains. We also found that a low sampling rate on mobile devices can affect recognition accuracy of complex and curved shapes. Despite this, we found no evidence to suggest that using a finger as an input implement leads to a decrease in simple shape recognition accuracy. These results show that the same geometric shape recognizers developed for pen applications can be used in mobile applications, provided that developers keep shape domains simple and ensure that input sampling rate is kept as high as possible.

Visual Localisation of Mobile Devices in an Indoor Environment under Network Delay Conditions  

E-Print Network (OSTI)

Current progresses in home automation and service robotic environment have highlighted the need to develop interoperability mechanisms that allow a standard communication between the two systems. During the development of the DHCompliant protocol, the problem of locating mobile devices in an indoor environment has been investigated. The communication of the device with the location service has been carried out to study the time delay that web services offer in front of the sockets. The importance of obtaining data from real-time location systems portends that a basic tool for interoperability, such as web services, can be ineffective in this scenario because of the delays added in the invocation of services. This paper is focused on introducing a web service to resolve a coordinates request without any significant delay in comparison with the sockets.

Context-Aware Service Utilisation in the Clouds and Energy Conservation  

E-Print Network (OSTI)

Ubiquitous computing environments are characterised by smart, interconnected artefacts embedded in our physical world that are projected to provide useful services to human inhabitants unobtrusively. Mobile devices are becoming the primary tools of human interaction with these embedded artefacts and utilisation of services available in smart computing environments such as clouds. Advancements in capabilities of mobile devices allow a number of user and environment related context consumers to be hosted on these devices. Without a coordinating component, these context consumers and providers are a potential burden on device resources; specifically the effect of uncoordinated computation and communication with cloud-enabled services can negatively impact the battery life. Therefore energy conservation is a major concern in realising the collaboration and utilisation of mobile device based context-aware applications and cloud based services. This paper presents the concept of a context-brokering component to aid...

Defeating Internet attacks and Spam using "disposable" Mobile IPv6 home addresses  

E-Print Network (OSTI)

We propose a model of operation for next generation wireless Internet, in which a mobile host has hundreds of "disposable" Mobile IPv6 home addresses. Each correspondent is distributed a different disposable home address. If attacked on a given home address, the mobile user can block packets to that address and become unreachable to the attacker. Blocking one address does not affect other addresses. Other correspondents can still reach the mobile host. A new home address can also be requested via e-mail, instant messaging, or directly from the target host using a protocol that we develop. This model is especially useful against battery exhausting Denial-of-Service (DoS) attacks and CPU exhausting distributed DoS attacks, since it seems to be the only viable solution, currently. We show however that this model can also be used to defeat other attacks and also to stop spam.

HOST GALAXIES OF X-SHAPED RADIO SOURCES  

SciTech Connect

Most radiation from galaxies containing active galactic nuclei (AGNs) is emitted not by the stars composing the galaxy, but from an active source at the galactic center, most likely a supermassive black hole. Of particular interest are radio galaxies, active galaxies that emit much of their radiation at radio wavelengths. Within each radio galaxy, an AGN powers a pair of collimated jets of relativistic particles, forming a pair of giant lobes at the end of the jets and thus giving a characteristic double-lobed appearance. A particular class of radio galaxies has an “X”-or winged-shaped morphology: in these, two pairs of lobes appear to originate from the galactic center, producing a distinctive X-shape. Two main mechanisms have been proposed to explain the X-shape morphology: one being a realignment of the black hole within the AGN and the second positing that the radio jets are expanding into an asymmetric medium, causing backflow and producing secondary wings. By analyzing radio host galaxy shapes, the distribution of the stellar mass is compared to the differing model expectations regarding the distribution of the surrounding gas and stellar material about the AGN. Results show elliptical host galaxies with an orthogonal offset between the semi-major axis of the host galaxy and the secondary radio wings, which lends support to the hydrodynamical model. However, results also show circular host galaxies with radio wings, making the realignment scenario a more likely model to describe the formation of these X-shaped radio sources.

Combinatorial mobile IP: a new efficient mobility management using minimized paging and local registration  

E-Print Network (OSTI)

Abstract. Combinatorial Mobile IP, a new mobility management scheme for Mobile IP, is proposed and analyzed. We present how to adopt mobility management schemes on cellular networks and adapt them in Mobile IP without disrupting the nature of the Internet. We apply widely used mobility management schemes such as hierarchical architecture and paging in cellular networks to Mobile IP. We restrict paging to the area that has to be paged using local registrations. In this way, we show that the total signaling costs of Combinatorial Mobile IP are reduced compared to other micro-mobility protocols such as Mobile IP Regional Registration and P-MIP. Random walk on a connected graph is used to analyze the performance of Combinatorial Mobile IP.

A giant radio jet ejected by an ultramassive black hole in a single-lobed radio galaxy  

E-Print Network (OSTI)

We report the discovery of a very unusual, highly asymmetric radio galaxy whose radio jet, the largest yet detected, emits strongly polarized synchrotron radiation and can be traced all the way from the galactic nucleus to the hot spot located ~440 kpc away. This jet emanates from an extremely massive black hole (>10^9 solar mass) and forms a strikingly compact radio lobe. No radio lobe is detected on the side of the counterjet, even though it is similar to the main jet in brightness up to a scale of tens of kiloparsecs. Thus, contrary to the nearly universal trend, the brightness asymmetry in this radio galaxy increases with distance from the nucleus. With several unusual properties, including a predominantly toroidal magnetic field, this Fanaroff-Riley type II megajet is an exceptionally useful laboratory for testing the role of magnetic field in jet stabilization and radio lobe formation.

The Extended GMRT Radio Halo Survey I: New upper limits on radio halos and mini-halos  

E-Print Network (OSTI)

A fraction of galaxy clusters host diffuse radio sources called radio halos, radio relics and mini-halos. We present the sample and first results from the Extended GMRT Radio Halo Survey (EGRHS)- an extension of the GMRT Radio Halo Survey (GRHS, Venturi et al. 2007, 2008). It is a systematic radio survey of galaxy clusters selected from the REFLEX and eBCS X-ray catalogs . Analysis of GMRT data at 610/ 235/ 325 MHz on 12 galaxy clusters are presented. We report the detection of a newly discovered mini-halo in the cluster RXJ1532.9+3021 at 610 MHz. A small scale relic (~200 kpc) is suspected in the cluster Z348. We do not detect cluster-scale diffuse emission in 11 clusters. Robust upper limits on the detection of radio halo of size of 1 Mpc are determined. We also present upper limits on the detections of mini-halos in a sub-sample of cool-core clusters. The upper limits for radio halos and mini-halos are plotted in the radio power- X-ray luminosity plane and the correlations are discussed. Diffuse extended e...

Accountability as a service  

E-Print Network (OSTI)

We propose that accountability be a first-class network service, independent of addressing and routing. We design a scheme for allowing accountability services, rather than connectivity-providing ISPs, to vouch for traffic, allowing victims to report abuse, filter abusive traffic, and isolate malicious senders. We discuss how accountability services may evolve, how they may facilitate new applications, and the implications of shifting the burden of network policing to a dedicated service. 1

Radio Astronomy Software Defined Receiver Project  

SciTech Connect

The paper describes a Radio Astronomy Software Defined Receiver (RASDR) that is currently under development. RASDR is targeted for use by amateurs and small institutions where cost is a primary consideration. The receiver will operate from HF thru 2.8 GHz. Front-end components such as preamps, block down-converters and pre-select bandpass filters are outside the scope of this development and will be provided by the user. The receiver includes RF amplifiers and attenuators, synthesized LOs, quadrature down converters, dual 8 bit ADCs and a Signal Processor that provides firmware processing of the digital bit stream. RASDR will interface to a user s PC via a USB or higher speed Ethernet LAN connection. The PC will run software that provides processing of the bit stream, a graphical user interface, as well as data analysis and storage. Software should support MAC OS, Windows and Linux platforms and will focus on such radio astronomy applications as total power measurements, pulsar detection, and spectral line studies.

Ion mobility spectrometers and methods for ion mobility spectrometry  

SciTech Connect

An ion mobility spectrometer may include an inner electrode and an outer electrode arranged so that at least a portion of the outer electrode surrounds at least a portion of the inner electrode and defines a drift space therebetween. The inner and outer electrodes are electrically insulated from one another so that a non-linear electric field is created in the drift space when an electric potential is placed on the inner and outer electrodes. An ion source operatively associated with the ion mobility spectrometer releases ions to the drift space defined between the inner and outer electrodes. A detector operatively associated with at least a portion of the outer electrode detects ions from the drift space.

The Economic Mobility in Money Transfer Models  

E-Print Network (OSTI)

In this paper, we investigate the economic mobility in some money transfer models which have been applied into the research on monetary distribution. We demonstrate the mobility by recording the agents' ranks time series and observing the volatility. We also compare the mobility quantitatively by employing an index, "the per capita aggregate change in log-income", raised by economists. Like the shape of distribution, the character of mobility is also decided by the trading rule in these transfer models. It is worth noting that even though different models have the same type of distribution, their mobility characters may be quite different.

Mobility control of caustic flood  

SciTech Connect

Displacement tests to date of oil field core with alkaline solutions at reservoir temperature show low tertiary oil recovery. Inadequate mobility control is singled out as the reason for such poor recovery. To test the validity of this reasoning, a laboratory study was undertaken in which a high heat resistant polymer was used as the mobility control agent in a hot alkaline solution recovery technique. A combination of varying concentration and volumes of the polymer solution was injected into the sandpack which was then flooded with hot sodium hydroxide solution. The range of polymer concentration was between 0.0% and 3.0%, while the volume varied between 0.0 pore volume and 1.7 pore volume. It was observed that polymer injection actually did improve recovery substantially and that there is an optimum concentration and slug size of polymer for a particular reservoir. Higher concentrations of pore volumes injected did not improve recovery significantly.

PKS0347+05: a radio-loud/radio-quiet double AGN system triggered in a major galaxy merger  

E-Print Network (OSTI)

We present optical, infrared and radio observations of the powerful FRII radio source PKS0347+05 (z=0.3390), and demonstrate that it is a rare example of a radio-loud/radio-quiet double AGN system, comprising a weak line radio galaxy (WLRG) separated by 25 kpc (in projection) from a Seyfert 1 nucleus at the same redshift. Our deep Gemini optical images show a highly disturbed morphology, with a warped dust lane crossing through the halo and nuclear regions of the radio galaxy host, tidal tails, and a bridge connecting the radio galaxy to the Seyfert 1 nucleus. Spectral synthesis modelling of our Gemini optical spectrum of the radio galaxy shows evidence for a reddened young stellar population of age <100 Myr. Further evidence for recent star formation activity in this source is provided by the detection of strong PAH features in mid-IR Spitzer/IRS spectra. Together, these observations support a model in which both AGN have been triggered simultaneously in a major galaxy merger. However, despite the presenc...

The Nature of Microjansky Radio Sources and Implications for the Design of the Next Generation Very Sensitive Radio Telescopes  

E-Print Network (OSTI)

Deep radio surveys show a population of very red counterparts of microjansky radio sources, which are unidentified to I = 25 in ground based images and I = 28.5 in the Hubble Deep Field. This population of optically faint radio sources, which comprises about 20% of the microjansky radio samples, may be dust enshrouded starburst galaxies, extreme redshift or dust reddened AGN, or due to displaced radio lobes. Even deeper radio surveys, which will be made possible by next generation radio telescopes such as the Expanded VLA or the Square Kilometer Array, will reach to nanojansky levels which may be dominated by this new population, but only if special care is taken to achieve high angular resolution and dynamic range better than 60 dB. This will reuire array dimensions up to 1000 km to achieve confusion limited performance at 1.4 GHz and up to 10,000 km at 300 MHz. But, even then, the ability to study individual nanojanksy radio sources may be limited by the finite extent of the sources and consequential blending of their images.

Probabilistic image reconstruction for radio interferometers  

E-Print Network (OSTI)

We present a novel, general-purpose method for deconvolving and denoising images from gridded radio interferometric visibilities using Bayesian inference based on a Gaussian process model. The method automatically takes into account incomplete coverage of the uv-plane and mode coupling due to the beam. Our method uses Gibbs sampling to efficiently explore the full posterior distribution of the underlying signal image given the data. We use a set of widely diverse mock images with a realistic interferometer setup and level of noise to assess the method. Compared to results from a proxy for the CLEAN method we find that in terms of RMS error and signal-to-noise ratio our approach performs better than traditional deconvolution techniques, regardless of the structure of the source image in our test suite.

Distributed service composition  

E-Print Network (OSTI)

In this paper we explore the use of action systems for distributed service composition. Distributed systems can be composed out of a basic computation and a set of services. Even though this way of designing a system out of components helps in managing the derivation task, formal description techniques are needed due to the complexity of distributed systems. We propose a method where services, or features as they are often called, are speci ed in isolation by the service provider. The services when available are used by clients in a distributed manner. Reasoning about the services and their interactions with each other and with the basic computation of the clients is carried out within the re nement calculus. To exemplify the proposed methodology we study feature composition and feature interaction in telecommunications software.
