Importance, Identification, and Assessment of Danger and Hazard Trees Located Outside Electric Transmission Line Rights-of-Way  

Science Conference Proceedings (OSTI)

Electric transmission line rights-of-way (ROWs) commonly pass through forested areas across North America. Trees from these forests could fall from outside the ROW into a transmission line and its security zone, potentially causing an outage. Most of the bulk transmission outages across the United States over the past decade have been caused by off-ROW trees. The North American Electric Reliability Corporation (NERC) developed standards for transmission vegetation management programs that strictly regul...

Managing Commercial Tree Species for Timber Production and Carbon Sequestration: Management Guidelines and Financial Returns  

SciTech Connect

A carbon credit market is developing in the United States. Information is needed by buyers and sellers of carbon credits so that the market functions equitably and efficiently. Analyses have been conducted to determine the optimal forest management regime to employ for each of the major commercial tree species so that profitability of timber production only or the combination of timber production and carbon sequestration is maximized. Because the potential of a forest ecosystem to sequester carbon depends on the tree species, site quality and management regimes utilized, analyses have determined how to optimize carbon sequestration by determining how to optimally manage each species, given a range of site qualities, discount rates, prices of carbon credits and other economic variables. The effects of a carbon credit market on the method and profitability of forest management, the cost of sequestering carbon, the amount of carbon that can be sequestered, and the amount of timber products produced has been determined.

Gridling Trees  

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

Gridling Trees Gridling Trees Name: Ellen Location: N/A Country: N/A Date: N/A Question: I need help!!!! Rabbits gridled three of my new trees last week. I am a first-time tree planter and I had no idea that this would happen and the folks at the nursery hadn't told us that this was a danger. The bark is gone. Is there any way I can save these trees? The trees are about seven feet tall. They are a crabapple, a dogwood, and an Eastern redbud. Is there any such thing as an artificial bark that I can put on them? Thank you for your help. Ellen Replies: Dear Ellen, "How can I save a tree that's been girdled by rabbits this winter? Can it be saved? That depends on several factors. How large is the tree? How much bark is girdled away? Girdling cuts off the tree's transportation system and could kill it. To prevent further damage from rabbits use a cage made of hardware mesh 1/4-inch. Enclose trunk far enough from bark to allow trunk diameter to expand as tree matures, and at least two feet higher than expected snow line. To protect against mice and voles push mesh two inches into the ground. (Protecting Trees and Shrubs Against Winter Damage, MES FO-1411-B.) "

Optimal nitrogen application rates for three intensively-managed hardwood tree species in the southeastern USA.  

SciTech Connect

Forest production can be limited by nutrient and water availability, and tree species are expected to respond differently to fertilization and irrigation. Despite these common expectations, multi-species comparisons are rare, especially ones implementing a range of fertilization rates crossed with irrigation. This study compares the response of three forest hardwood species to numerous nitrogen (N) fertilization levels and water availability using a novel non-replicated technique. A range of N levels was included to determine how N affected the growth response curve, and statistical procedures for comparing these non-linear response functions are presented. We used growth and yield data to calculate the Land Expectation Value (LEV) for these intensive management treatments, and to determine the optimal growing conditions (accounting for tree productivity and grower expenses). To accomplish these objectives, we used a series of cottonwood, sycamore, and sweetgum plots that received a range of N fertilization with or without irrigation. Regression is an economical approach to define treatment responses in large-scale experiments, and we recommend >3 treatment levels so the response of any single plot does not disproportionally influence the line. The non-replicated plots showed a strong positive N response below 150 kg N ha -1 yr -1, beyond which little response was observed. However, different amounts of fertilization were required for the greatest biomass accumulation rate in each tree species. Cottonwood and sycamore growth was optimized with less than 150 kg N ha -1 yr -1 while sweetgum growth was optimized with less than 100 kg N ha -1 yr -1. Results from this experiment should be representative of many of the nutrient-poor soils in the Coastal Plain in the southeastern USA. The LEVs were not positive for any treatment x genotype combination tested when using irrigation or liquid fertilizer, but our analysis showed that several non-irrigated treatments in sycamore and sweetgum did result in positive LEVs when fertilized with granular urea.

Dangerous electromagnetic fields?

Dangerous electromagnetic fields? Dangerous electromagnetic fields? Name: Tommy T Joseph Location: N/A Country: N/A Date: N/A Question: Why are electromagnetic fields supposedly dangerous? Replies: I assume you are asking about power line frequency (60 Hz) fields, since they have been in the news lately. No one knows for sure that they are dangerous. There have been a few studies which seem to show an association between how close homes are to power lines, and the incidence of childhood cancer (mostly leukemia) in children living (or who have lived) in those homes. Other similar studies have not found such an association. In all the studies which have found an association, none has actually measured the fields. Studies which actually have measured the fields find no association. There is no known mechanism for 60 Hz fields to cause cancer. Furthermore, the classic "dose-response relationship," that is, the greater the dose, the greater the response, does not seem to work here. Many laboratory studies have found that 60 Hz fields have an effect on organisms under certain conditions, but none of the observed effects can be convincingly related to a hazard. The bottom line is, no one knows for sure. It is important to realize that it is impossible to prove that anything is completely safe. My personal opinion is that, if there is a risk, it must be very small, or it wouldn't be so hard to prove. I can supply some good unbiased references if you are interested.

Tree Pests Tree Pests Name: Eric Location: N/A Country: N/A Date: N/A Question: I have found an odd species of borer infesting the trees in my area. It does not confine itself to any single species, but seems to move from tree to tree, somewhat like a plague. They originated in a stand of Chinese elm (ulmus parvifolia) and then moved to our bur oaks (quercus macrocarpa) and our native version of white ash (fraxinus americana). As these trees are few and far between, the borers have recently moved to the cottonwoods (populus deltoides) which line the creeks. The borers cut a half inch wide hole, usually straight into the trunk. They kick out mounds of sawdust every so often, and attempts to plug thier holes are removed, always during the evening. I recently was forced to destroy some of the elms as they had been completely ransacked by these borers, a cut into the trunks revealed five bore holes within two inches of each other, with 4 more spaced farther away. I did manage to track down one of the borers in the log. It was about 2 inches long, with reddish pink coloring and black "spines" all along it. It had a sickly white underside to it also. I was wondering if you could possibly say what type of borer this is, I suspect some kind of carpenterworm, but the local government offices have been no help. I would like to at least slow these things down in time to save the Ashes and Oaks, some of which are over three-hundred years old, which is virtually unknown in my area. (northwest Kansas) Thanks for your help!

Cultural and management practices for the Chinese tallow tree as a biomass fuel source: Final report, 1978-1984  

SciTech Connect

The growth and cultural conditions of the Chinese tallow tree, Sapium sebiferum (L.) Roxb., were studied over a 6-year period. Plots from seeds or seedlings at designated densities and plots established in natural stands were studied. The maximum growth rate of the Chinese tallow tree in a marginal soil near the Texas gulf coast was 10 to 15 dry tons/hectare/year. The young trees were able to withstand long periods of flooding as well as extended dry periods. The tree species also is resistant to diseases and pathogens. The Chinese tallow tree is particularly adaptable to close spacing, direct seeding, coppicing, and short-rotation growth cycles. These factors all favor the economic usefulness of the tree as a bioenergy species. In addition, the tallow tree is economically valuable in honey production and as a chemical feedstock. Fertilization is important during the early phases of stand establishment but has diminished usefulness in subsequent years. The Chinese tallow tree appears to be an excellent bioenergy species in the southern coastal areas of the United States and especially in marginal soils. The Chinese tallow tree has the potential of producing 15 to 20 tons/hectare annually by coppicing on a 5- to 8-year rotation at close spacings. 12 figs., 12 tabs.

Banana Trees Banana Trees Name: Adele Location: N/A Country: N/A Date: N/A Question: Why do Banana trees grow bananas?? I've been asked this question and no-one I know can provide an answer! Bananas do not have seeds in them to reproduce the tree (e.g you can grow a lemon tree from the seeds in the fruit but not a banana tree from a banana) What evolutionary justification is there for a banana tree to bear fruit? Replies: Hi Adele! you are right, one cannot seed a banana tree, still that kind of vegetal is reproduced and grows... As many other plants they have an asexual reproduction, where the new plants are identical in every respect to the parent plant.The asexual reproduction involves no union of cells or nuclei of cells, there are not mingling of genetic traits. Banana plant is a gigantic herb that grows from an under- ground stem ( rhizome),and forms a false trunk with leaves. There emerges a large flower spike, with numerous individual flowers, that bends downward to become fruits. After the plants had fruits, they die and are replaced by others that arise from the underground stem, and that process can keep on going for many years. Right?

Eisenbeis, Supt. of Conservation TREE FLOWERS Many people do not realize that all of our common trees have flowers. Otherwise they could not produce seeds. We are apt to think of flowering trees as being those with showy blossoms -- most of them beautiful and some very fragrant -- such as the redbud, dogwood, buckeye, horse chestnut, black locust, tulip tree or yellow poplar, magnolia, and the fruit trees. However, all of our forest and shade trees have flowers -- of some kind -- which are just as interesting when examined with a strong reading glass. Some are grotesque, some exquisitely designed, some extremely colorful. They offer a new world to be explored and photographed. Some kinds, such as the elms, bloom profusely but the flowers are so small and delicately tinted that they are seldom noticed. Others, such as the poplars, oaks and walnuts, have peculiar flowers in the form of catkins that, without petals or sepals, do not look like flowers at all. The sycamore's tiny flowers are packed, in countless numbers, into a tight round ball that dangles back and forth on a long flexible stem.

Eisenbeis, Supt. of Conservation TREE DIARIES We know a man whose life, as a civil engineer on construction projects, had been spent mostly out-of-doors but he knew very little about the plants and animals he saw. In 1945, after a long severe winter, March was usually warm and sunny. The birds came back north, the wildflowers bloomed, and the trees leafed out much earlier than in any year he could remember. So he spent every morning, from daybreak until time to go to work, walking through a forest preserve near his home, and he kept a diary of everything he saw. He had been doing that every year since 1945. He not only has some very valuable records but, in the meantime, by observing them carefully and studying about them in books, he has come to know more than most people about wildflowers, weeds, trees, birds, insects and other animals, and has had a lot of fun. Phenology, as it is called, can be an absorbing hobby and one of the best teachers. You also learn what an important factor weather is. For instance, there may be a difference of as much as a month in the earliest date of blooming of the skunk cabbage.

HANFORD FACILITY ANNUAL DANGEROUS WASTE REPORT CY2003 [SEC 1 & 2  

Science Conference Proceedings (OSTI)

The Hanford Facility Annual Dangerous Waste Report (ADWR) is prepared to meet the requirements of Washington Administrative Code Sections 173-303-220, Generator Reporting, and 173-303-390, Facility Reporting. In addition, the ADWR is required to meet Hanford Facility RCRA Permit Condition I.E.22, Annual Reporting. The ADWR provides summary information on dangerous waste generation and management activities for the Calendar Year for the Hanford Facility EPA ID number assigned to the Department of Energy for RCRA regulated waste, as well as Washington State only designated waste and radioactive mixed waste. The Solid Waste Information and Tracking System (SWITS) database is utilized to collect and compile the large array of data needed for preparation of this report. Information includes details of waste generated on the Hanford Facility, waste generated offsite and sent to Hanford for management, and other waste management activities conducted at Hanford, including treatment, storage, and disposal. Report details consist of waste descriptions and weights, waste codes and designations, and waste handling codes. In addition, for waste shipped to Hanford for treatment and or disposal, information on manifest numbers, the waste transporter, the waste receiving facility, and the original waste generators are included. In addition to paper copies, the report is also transmitted electronically to a web site maintained by the Washington State Department of Ecology.

Tree Decorations Tree Decorations Nature Bulletin No. 211-A December 18, 1965 Forest Preserve District of Cook County Seymour Simon, President Roland F. Eisenbeis, Supt. of Conservation CHRISTMAS TREE DECORATIONS Christmas trees, decorated or "trimmed", apparently were first used in this country during the Revolutionary War by Hessian soldiers who, hired to fight for England, were thinking of the customs in their German homeland. An account of the festivities here at Fort Dearborn, in 1804, mentions a spruce Christmas tree. Some say that a Harvard professor from Germany had one in 1824. There is reliable evidence that there was such a tree in Cambridge, Mass., in 1832; and in Philadelphia two years later. The idea and the tradition spread rapidly through this country.

Replies: Taylor Peach trees are deciduous, so yes, they lose their leaves: http://www.ehow.com/facts_7021010_information-deciduous-fruit-trees-florida.html Anthony R. Brach, Ph.D. Harvard University Herbaria c/o Missouri Botanical Garden This depends on the latitude. South of Immokalee, peach trees could stay evergreen year-round. However, they also will not bear fruit because a "chilling period" is needed to prime the tree for production in the spring. It simply doesn't get cool enough to pull this physiological trigger. Otherwise, a tree should drop its leaves in preparation for winter dormancy. If the early winter has been unseasonably warm and the trees have not dropped their leaves by mid-December, then a zinc sulfate solution can be applied to artificially induce defoliation.

Trees in the winter  

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

Trees in the winter Trees in the winter Name: John H Hersey Age: N/A Location: N/A Country: N/A Date: N/A Question: Why do some trees in the winter lose their leaves and some are able to keep their leaves? Replies: John, You can view the leaves on a tree as its food manufacturing factory. For some trees, especially those which live in areas which become cold in the winter, the 'factories' do their work during the normal growing season and are forced to 'shut-down' over the winter months. There are many evergreens which hold their foliage all year, simply dropping some of them periodically as they age and become less efficient to be replaced by new needles. Larches in the area where I live are conifers which lose their needles, which is quite rare. You can see that foliage on a tree presents a problem: water loss from a tree is greatest in its foliage. A tree has to 'decide' (and this has occurred over millennia by evolution) whether to hold its foliage or shed it. If it decides to hold the foliage, then it must provide a means of insuring conservation of water, especially in the winter months when dry cold winds remove water which is not easily replace due to liquid water in the environment being frozen. Many plant's adaptation has been the production of a waxy cuticle to 'seal-off' the leaf from the environment and reduce water loss. You can understand that in the northern latitude's winters, sunlight duration and intensity drops, and for some plants the best solution has involved shedding the leaves for the winter, and growing a new set of 'factories' in the spring.

Source Tree Composition  

E-Print Network (OSTI)

Dividing software systems in components improves software reusability as well as software maintainability. Components live at several levels, we concentrate on the implementation level where components are formed by source files, divided over directory structures. Such source code components are usually strongly coupled in the directory structure of a software system. Their compilation is usually controlled by a single global build process. This entangling of source trees and build processes often makes reuse of source code components in different software systems difficult. It also makes software systems inflexible because integration of additional source code components in source trees and build processes is difficult. This paper's subject is to increase software reuse by decreasing coupling of source code components. It is achieved by automized assembly of software systems from reusable source code components and involves integration of source trees, build processes, and configuration processes. Application domains include generative programming, product-line architectures, and commercial off-the-shelf (COTS) software engineering.

Tree transport system  

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

Tree transport system Tree transport system Name: Paul K Harding Location: N/A Country: N/A Date: N/A Question: How can trees get that tall? How can the transport of water function that good? Normally one could think that trees can get only 10 m high because then the pressure of the air would be to weak to transport the water and a vacuum would occur. Or do trees use a system of one pump-system after another to solve that problem? Replies: Okay, the answer is two-fold. One, the column of water travelling up the trunk of the tree is only a couple of molecules wide, moving up from cell to cell. You can think of each cell as a "valve" if you will, holding the water and keeping it from flowing down the trunk (unless you WANT it to go that way, in the case of sugar laden water moving to storage areas in the roots) until it can be moved to the next cell up, and so on and so on. The second part involves diffusion. Cells can diffuse certain chemical compounds through their cell walls while simultaneously holding onto others. By having a gradient of increasing chemical concentration as you go up the trunk, you can cause a gradual diffusion of water up the trunk (since water travels relatively freely through the cell walls) and thereby creates and exception to the rule of 10 meters being the maximum height for a column of water -- you've effectively added energy to the system to "pump" water up the trunk.

Fossil turbulence and fossil turbulence waves can be dangerous  

E-Print Network (OSTI)

Turbulence is defined as an eddy-like state of fluid motion where the inertial-vortex forces of the eddies are larger than any other forces that tend to damp the eddies out. By this definition, turbulence always cascades from small scales where vorticity is created to larger scales where turbulence fossilizes. Fossil turbulence is any perturbation in a hydrophysical field produced by turbulence that persists after the fluid is no longer turbulent at the scale of the perturbation. Fossil turbulence patterns and fossil turbulence waves preserve and propagate energy and information about previous turbulence. Ignorance of fossil turbulence properties can be dangerous. Examples include the Osama bin Laden helicopter crash and the Air France 447 Airbus crash, both unfairly blamed on the pilots. Observations support the proposed definitions, and suggest even direct numerical simulations of turbulence require caution.

New England Wind Forum: Am I in Danger?  

Wind Powering America (EERE)

Am I in Danger? Am I in Danger? With tens of thousands in operation across the world, wind turbines have demonstrated an excellent safety track record. Primary safety issues of concern are the icing of the blades and resulting shedding of the ice and the potential impact of a blade throw. Ice Shedding Under certain conditions in climates such as those found in New England, ice can accumulate on wind turbine blades. The release of that ice from moving turbine blades is possible. (The potential is clearly highest at mountain-top sites, remote from most observers in the harshest of weather.) A wind installation typically addresses such possibilities by employing adequate setbacks between each turbine and any nearby residences to avoid risk. Severe ice buildup will lead to automatic turbine shut down until the condition improves. Modern turbines can be equipped with cold weather packages, which make them adaptable to temperatures as low as -40 Celsius, reducing the risk of ice accumulation. These packages include special coatings on the blades to eliminate the adherence of ice, thermostat-controlled resistive element forced air heaters strategically placed to heat instruments and operating components during cold weather conditions to prevent the formation and adherence of ice, and low-temperature lubricants. No studies have been conducted in the United States concerning ice shedding from wind turbine blades. The 1998 European study, "Assessment of Safety Risks Arising from Wind Turbine Icing" (PDF 57 KB) Download Adobe Reader by European Commission, DGXII, and the UK Department of Trade and Industry examines the issue as well as the study "Risk Analysis of Ice Throw From Wind Turbines" (PDF 297 KB) Download Adobe Reader presented in April 2003 at BOREAS conference in Finland.

Like several others, it was a translation by scholars who were not botanists, had never visited the Holy Land, did not realize that the native plants in that region were far different from plants in northern Europe, and made the mistake of identifying some of those mentioned in the Scriptures with familiar plants in England.

Tree Hole Tree Hole Nature Bulletin No. 581 November 21, 1959 Forest Preserve District of Cook County Daniel Ryan, President Roberts Mann, Conservation Editor David H Thompson, Senior Naturalist LIFE IN A TREE HOLE A forest is much more than just trees. It includes all of the underbrush, wildflowers and other vegetation that grow beneath these trees; as well as all of its animal life, both large and small. Sunshine, rain, wind, soil, and the leaf litter on the ground are part of it, too. A forest is a community -- a fabric in which the lives of its inhabitants are woven together and into their surroundings by a complex web of interrelations. Tree holes -- together with the birds, mammals and small life which they shelter -- furnish an important binding force in this forest community.

Schematisation of Tree Drawings  

E-Print Network (OSTI)

Abstract. Given a tree T spanning a set of points S in the plane, we study the problem of drawing T using only line segments aligned with a fixed set of directions C. The vertices in the drawing must lie within a given distance r of each original point p ? S, and an objective function counting the number of bends must be minimised. We propose five versions of this problem using different objective functions, and algorithms to solve them. This work has potential applications in geographic map schematisation and metro map layout. 1

Management  

E-Print Network (OSTI)

Research has indicated that, depending upon driver and passenger characteristics, passengers can have either a positive or negative influence upon driver behaviour. In conclusion to a recent study investigating the roles that passengers can play to influence, positively and negatively, driver behaviour, Regan and Mitsopoulos (2001) recommended, among other things, that the principles of Crew Resource Management (CRM) training may increase passengers ability to positively influence driver behaviour and also drivers ability to accept constructive feedback. The present study investigated the potential application of CRM training within young driver training in the Australian Capital Territory (ACT). This involved a literature review, an analysis of the differences between the driving and aviation domains, an analysis of the team-based activities and the knowledge, skills and attitudes required during driving to perform those activities, consultation with CRM experts from the aviation and medicine domains and the conduct of six focus groups involving young learner drivers, provisional licence drivers and course teachers. The findings indicate that CRM training as part of young driver training in the ACT is a viable concept to pursue. The application of CRM training within young driver training has potential to significantly enhance the positive and reduce the negative effects of passengers on young driver behaviour, and thus the safety of young drivers and passengers alike. The outcomes of this study formed the basis for a set of recommendations for the development of a young driver CRM training program in the ACT.

Energy efficiency, newly recognized overseas, can replace most dangerous nuclear plants  

Science Conference Proceedings (OSTI)

The cheapest way to achieve global energy/environmental goals is to encourage investment in efficiency overseas. Energy intensity is defined as E/GNP, where E = primary Energy and GNP = Gross National Product. E/GNP is 2-3 times higher in the 2nd (formerly communist) and 3rd (developing) worlds than in the {open_quotes}1st{close_quotes} (industrialized) world. In the 1st world E/GNP is dropping 1-2% year, but, except for China, it is still rising in worlds 2 and 3. For developing countries, E/GNP first rises with a need for heavy industry, then falls as efficiency improves and industry {open_quotes}lightens.{close_quotes} But there are 7 serious barriers against efficient use of energy. (1) Price. The price of energy is invariably subsidized. (2) Poor information, e.g., no fuel economy labels on cars, equipment, appliances. (3) Lack of choice. Little opportunity for comparison shopping. (4) Poor management. Industry still produces the wrong thing. (5) Ideological utility policy. Particularly in communist countries, energy and electrification were seen as manifest goods (the way we view wealth). (6) Ideological Western Institutions, particularly the World Bank and the regional development banks, who typically devoted rates for future savings-the poorer the consumer, the higher the discount rate. This skews the social investments in favor of more energy supply. Given the remarkable success of efficiency in the West, and the acceptance of {open_quotes}integrated utility planning{close_quotes} where utilities can diversify into more profitable investments on the customer side of the meter, all the barriers above are crumbling rapidly. It should be easy to replace all the dangerous nuclear plants in the former Soviet Union with just more efficient lamps and motors. Progress will be discussed quantitatively.

Tree leaves in the winter  

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

Tree leaves in the winter Tree leaves in the winter Name: ethel Location: N/A Country: N/A Date: N/A Question: Why do leaves fall off of some trees in the winter? Replies: An interesting question, Ethel. Biologists generally try to explain behavior in terms of a response or adaptation to an environmental challenge. The challenge in this example is thought to be snowfall. The idea is that a massive accumulation of snow in a large tree canopy would lead to mechanical damage or breakage of tree limbs or the trunk. Most deciduous trees (those that lose leaves in fall) have broad flat leaves that catch snow quite well. The advantage of this type of leaf is that they also catch the sunlight well in the summer growing season, allowing efficient photosynthesis to support rapid summer growth. The leaves are not needed in the winter because cold temperatures inhibit the enzymes of photosynthesis and prevent significant growth. Another interesting question is how evergreen trees have adapted to similar environmental challenges using a different strategy. Ask me a about it if you are interested.

Eucalyptus species are among the fastest growing woody plants in the world, with mean annual increments up to 100 cubic meter per hectare. Eucalyptus is the most valuable and most widely planted genus of plantation forest trees in the world (ca. 18 million hectares) due to its wide adaptability, extremely fast growth rate, good form, and excellent wood and fiber properties. Eucalyptus is also listed as one of the U.S. Department of Energy's candidate biomass energy

Bayesian Inference in Monte-Carlo Tree Search  

E-Print Network (OSTI)

Monte-Carlo Tree Search (MCTS) methods are drawing great interest after yielding breakthrough results in computer Go. This paper proposes a Bayesian approach to MCTS that is inspired by distributionfree approaches such as UCT [13], yet significantly differs in important respects. The Bayesian framework allows potentially much more accurate (Bayes-optimal) estimation of node values and node uncertainties from a limited number of simulation trials. We further propose propagating inference in the tree via fast analytic Gaussian approximation methods: this can make the overhead of Bayesian inference manageable in domains such as Go, while preserving high accuracy of expected-value estimates. We find substantial empirical outperformance of UCT in an idealized bandit-tree test environment, where we can obtain valuable insights by comparing with known ground truth. Additionally we rigorously prove on-policy and off-policy convergence of the proposed methods.

Parallel TreeSPH  

E-Print Network (OSTI)

We describe PTreeSPH, a gravity treecode combined with an SPH hydrodynamics code designed for massively parallel supercomputers having distributed memory. Our computational algorithm is based on the popular TreeSPH code of Hernquist & Katz (1989). PTreeSPH utilizes a domain decomposition procedure and a synchronous hypercube communication paradigm to build self-contained subvolumes of the simulation on each processor at every timestep. Computations then proceed in a manner analogous to a serial code. We use the Message Passing Interface (MPI) communications package, making our code easily portable to a variety of parallel systems. PTreeSPH uses individual smoothing lengths and timesteps, with a communication algorithm designed to minimize exchange of information while still providing all information required to accurately perform SPH computations. We have additionally incorporated cosmology, periodic boundary conditions with forces calculated using a quadrupole Ewald summation method, and radiative cooling and heating from a parameterized ionizing background following Katz, Weinberg & Hernquist (1996). The addition of other physical processes, such as star formation, is straightforward. A cosmological simulation from z=49 to z=2 with 64^3 gas particles and 64^3 dark matter particles requires ~6000 node-hours on a Cray T3D, with a communications overhead of ~10% and is load balanced to a ~90% level. When used on the new Cray T3E, this code will be capable of performing cosmological hydrodynamical simulations down to z=0 with ~2x10^6 particles, or to z=2 with ~10^7 particles, in a reasonable amount of time. Even larger simulations will be practical in situations where the matter is not highly clustered or when periodic boundaries are not required.

Joshua Tree and Mojave Go Solar  

DOE Green Energy (OSTI)

This case study describes two of the many projects in which the Department of the Interior's National Park Service works with private contractors and other agencies, such as the Department of Energy's Federal Energy Management Program (FEMP), to replace fossil-fuel-powered diesel generators with renewable energy systems in the nation's parks. This is done to reduce the greenhouse-gas emissions, such as carbon dioxide and nitrous oxides, associated with using fossil fuels to generate electric power in remote areas of the parks. Two solar electric (photovoltaic) systems were installed in Joshua Tree National Park and Mojave National Preserve in southern California, and more are planned. The systems are cleaner and less noisy than the old generators they replaced; they are connected to storage batteries and backed up by new propane generators in case of a prolonged period without sunlight.

Rotor walks on general trees  

E-Print Network (OSTI)

The rotor walk on a graph is a deterministic analogue of random walk. Each vertex is equipped with a rotor, which routes the walker to the neighbouring vertices in a fixed cyclic order on successive visits. We consider rotor walk on an infinite rooted tree, restarted from the root after each escape to infinity. We prove that the limiting proportion of escapes to infinity equals the escape probability for random walk, provided only finitely many rotors send the walker initially towards the root. For i.i.d. random initial rotor directions on a regular tree, the limiting proportion of escapes is either zero or the random walk escape probability, and undergoes a discontinuous phase transition between the two as the distribution is varied. In the critical case there are no escapes, but the walker's maximum distance from the root grows doubly exponentially with the number of visits to the root. We also prove that there exist trees of bounded degree for which the proportion of escapes eventually exceeds the escape p...

Hanford Facility Dangerous Waste Closure Plan - Plutonium Finishing Plant Treatment Unit Glovebox HA-20MB  

Science Conference Proceedings (OSTI)

This closure plan describes the planned activities and performance standards for closing the Plutonium Finishing Plant (PFP) glovebox HA-20MB that housed an interim status ''Resource Conservation and Recovery Act'' (RCRA) of 1976 treatment unit. This closure plan is certified and submitted to Ecology for incorporation into the Hanford Facility RCRA Permit (HF RCRA Permit) in accordance with Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement; TPA) Milestone M-83-30 requiring submittal of a certified closure plan for ''glovebox HA-20MB'' by July 31, 2003. Glovebox HA-20MB is located within the 231-5Z Building in the 200 West Area of the Hanford Facility. Currently glovebox HA-20MB is being used for non-RCRA analytical purposes. The schedule of closure activities under this plan supports completion of TPA Milestone M-83-44 to deactivate and prepare for dismantlement the above grade portions of the 234-5Z and ZA, 243-Z, and 291-Z and 291-Z-1 stack buildings by September 30, 2015. Under this closure plan, glovebox HA-20MB will undergo clean closure to the performance standards of Washington Administrative Code (WAC) 173-303-610 with respect to all dangerous waste contamination from glovebox HA-20MB RCRA operations. Because the intention is to clean close the PFP treatment unit, postclosure activities are not applicable to this closure plan. To clean close the unit, it will be demonstrated that dangerous waste has not been left at levels above the closure performance standard for removal and decontamination. If it is determined that clean closure is not possible or is environmentally impractical, the closure plan will be modified to address required postclosure activities. Because dangerous waste does not include source, special nuclear, and by-product material components of mixed waste, radionuclides are not within the scope of this documentation. Any information on radionuclides is provided only for general knowledge. Clearance form only sent to RHA.

Fast Tree: Computing Large Minimum-Evolution Trees with Profiles instead of a Distance Matrix  

Science Conference Proceedings (OSTI)

Gene families are growing rapidly, but standard methods for inferring phylogenies do not scale to alignments with over 10,000 sequences. We present FastTree, a method for constructing large phylogenies and for estimating their reliability. Instead of storing a distance matrix, FastTree stores sequence profiles of internal nodes in the tree. FastTree uses these profiles to implement neighbor-joining and uses heuristics to quickly identify candidate joins. FastTree then uses nearest-neighbor interchanges to reduce the length of the tree. For an alignment with N sequences, L sites, and a different characters, a distance matrix requires O(N^2) space and O(N^2 L) time, but FastTree requires just O( NLa + N sqrt(N) ) memory and O( N sqrt(N) log(N) L a ) time. To estimate the tree's reliability, FastTree uses local bootstrapping, which gives another 100-fold speedup over a distance matrix. For example, FastTree computed a tree and support values for 158,022 distinct 16S ribosomal RNAs in 17 hours and 2.4 gigabytes of memory. Just computing pairwise Jukes-Cantor distances and storing them, without inferring a tree or bootstrapping, would require 17 hours and 50 gigabytes of memory. In simulations, FastTree was slightly more accurate than neighbor joining, BIONJ, or FastME; on genuine alignments, FastTree's topologies had higher likelihoods. FastTree is available at http://microbesonline.org/fasttree.

A Contour Method on Cayley tree  

E-Print Network (OSTI)

We consider a finite range lattice models on Cayley tree with two basic properties: the existence of only a finite number of ground states and with Peierls type condition. We define notion of a contour for the model on the Cayley tree. By a contour argument we show the existence of $s$ different (where $s$ is the number of ground states) Gibbs measures.

Waste Management Process Improvement Project  

SciTech Connect

The Bechtel Hanford-led Environmental Restoration Contractor team's Waste Management Process Improvement Project is working diligently with the U.S. Department of Energy's (DOE) Richland Operations Office to improve the waste management process to meet DOE's need for an efficient, cost-effective program for the management of dangerous, low-level and mixed-low-level waste. Additionally the program must meet all applicable regulatory requirements. The need for improvement was highlighted when a change in the Groundwater/Vadose Zone Integration Project's waste management practices resulted in a larger amount of waste being generated than the waste management organization had been set up to handle.

Ambrosia Beetle (Coleoptera: Scolytidae) Species, Flight, and Attack on Living Eastern Cottonwood Trees.  

SciTech Connect

ABSTRACT In spring 2002, ambrosia beetles (Coleoptera: Scolytidae) infested an intensively managed 22-ha tree plantation on the upper coastal plain of South Carolina. Nearly 3,500 scolytids representing 28 species were captured in ethanol-baited traps from 18 June 2002 to 18 April 2004. More than 88% of total captures were exotic species. Five species [Dryoxylon onoharaensum (Murayama), Euwallacea validus (Eichhoff), Pseudopityophthorus minutissimus (Zimmermann), Xyleborus atratus Eichhoff, and Xyleborus impressus Eichhoff]) were collected in South Carolina for the ????rst time. Of four tree species in the plantation, eastern cottonwood, Populus deltoides Bartram, was the only one attacked, with nearly 40% of the trees sustaining ambrosia beetle damage. Clone ST66 sustained more damage than clone S7C15. ST66 trees receiving fertilization were attacked more frequently than trees receiving irrigation, irrigation_fertilization, or controls, although the number of S7C15 trees attacked did not differ among treatments. The study location is near major shipping ports; our results demonstrate the necessity for intensive monitoring programs to determine the arrival, spread, ecology, and impact of exotic scolytids.

D-Tree: a multi-dimensional indexing structure for constructing document warehouses  

E-Print Network (OSTI)

Document warehouses, unlike traditional document management systems, contain extensive semantic information about documents, cross-document feature relations, and document grouping or clustering, thus providing an accurate and efficient access to business intelligence information. Since documents are multi-dimensional in nature, we claim that traditional indexing methods are not really suitable for document warehousing. In this paper, we propose an indexing structure, called the D-tree, which can facilitate the construction of document cubes. We formally present the related definitions, the design of its storage structure and related algorithms for D-trees. The above are essential for establishing an infrastructure for combining text processing methods with numeric OLAP processing technologies. Hopefully, the proposed combination of data warehousing and document warehousing will be an important kernel for knowledge management and customer relationship management applications.

Until late 1998, Joshua Tree National Park and Until late 1998, Joshua Tree National Park and Mojave National Preserve in southern California used diesel generators to produce electricity in remote areas. Like many park energy systems, the diesel generators at Joshua Tree's Cottonwood Campground also produced potentially harmful emissions: 120 tons of carbon dioxide, 5,770 pounds of nitrous oxides, 286 pounds of sulfur dioxide, and 218 pounds of suspended particulates every year. Today, Joshua Tree has cut those emissions dramati- cally while reducing annual operating costs by an impressive 90%, thanks to a new photovoltaic (PV) system that harnesses the sun's energy to produce clean electric power.

Modeling the uptake and transpiration of TCE using phreatophytic trees. Master`s Thesis  

Science Conference Proceedings (OSTI)

Phytoremediation is a recent addition to the numerous methods used today to remediate ground water contaminants. It is proving more effective and efficient compared to existing remediation techniques. The use of phreatophytes, or water seeking trees, has great potential for phytoremediation. These trees are fast growing, long lived, grow their roots down to the ground water table, transpire large amounts of water, and are proven to actively remove contaminants from the soil horizon. The purpose of this research is to develop quantitative concepts for understanding the dynamics of TCE uptake and transpiration by phreatophytic trees over a short rotation woody crop time frame. This will he done by constructing a system dynamics model of this process and running it over a wide range of conditions. This research will offer managers a tool to simulate long-term uptake and transpiration of TCE at potential sites. The results of this study indicate that TCE is actively removed from the soil horizon by phreatophytic trees and a significant proportion of this TCE is then transpired. Changes in soil horizon parameters, xylem flow rates, and variables in the uptake equation greatly influence TCE uptake rates as well as transpiration. Also, parameters used in equations representing flows in and out of the leaf greatly influence transpiration. Better understanding of these processes is essential for managers to accurately predict the amount of TCE removed and transpired during potential phytoremediation projects.

New method for abbreviating the fault tree graphical representation  

SciTech Connect

Fault tree analysis is being widely used for reliability and safety analysis of systems encountered in the nuclear industry and elsewhere. A disadvantage of the fault tree method is the voluminous fault tree graphical representation that conventionally results from analysis of a complex system. Previous methods for shortening the fault tree graphical representation include (1) transfers within the fault tree, and (2) the use of the SAMPLE (K out of N logic) gate, the MATRIX gate, and the SUMMATION gate. The purpose of this presentation is to introduce TABULATION gates as a method to abbreviate the fault tree graphical representation. These new gates reduce the cost of analysis and generally increase the system behavior visibility that is inherent in the fault tree technique. (auth)

Cost and Productivity of Multi-Product Processing for Small Diameter Trees : Final Report.  

SciTech Connect

This project evolved from an effort by the land manager, the United States Forest Service, to economically deal with thousands of acres of thick (doghair) Douglas-fir and hemlock forests on Washington's Olympic Peninsula. These forests are very densely stocked and the trees are small. Until this effort, there has been no reasonable way to get enough product from the sites to justify managing them. And, even this project required some special agreements between the landowner and the investigator to be viable. This report describes the in-woods processing system now working in doghair stands on the Quilcene District. As whole trees arrive at the landing, they are sorted by a Cat 225 shovel-type loader. Sawlogs are trimmed, limbed, bucked, and decked for transportation on conventional log trucks. Chip grade trees are passed through a prototype, multi-stem debarker/delimber and then chipped by a Morbark 23'' Chiparvester. Clean chips are transported in regular highway chip vans. All other materials, not sold as logs or clean chips, are processed by a prototype shredder, and taken from the site as hogfuel. 7 ref., 15 figs., 11 tabs.

TREES AND BRANCHES IN BANACH SPACES  

E-Print Network (OSTI)

Abstract. An infinite dimensional notion of asymptotic structure is considered. This notion is developed in terms of trees and branches on Banach spaces. Every countably infinite countably branching tree T of a certain type on a space X is presumed to have a branch with some property. It is shown that then X can be embedded into a space with an FDD (Ei) so that all normalized sequences in X which are almost a skipped blocking of (Ei) have that property. As an application of our work we prove that if X is a separable reflexive Banach space and for some 1 0, there exists a finite codimensional subspace of X which C 2 + ? embeds into the ?p sum of finite dimensional spaces. 1.

Approximating stochastic volatility by recombinant trees  

E-Print Network (OSTI)

A general method to construct recombinant tree approximations for stochastic volatility models is developed and applied to the Heston model for stock price dynamics. In this application, the resulting approximation is a four tuple Markov process. The ?first two components are related to the stock and volatility processes and take values in a two dimensional Binomial tree. The other two components of the Markov process are the increments of random walks with simple values in {-1; +1}. The resulting effi?cient option pricing equations are numerically implemented for general American and European options including the standard put and calls, barrier, lookback and Asian type pay-o?ffs. The weak and extended weak convergence are also proved.

Finding cycles and trees in sublinear time.  

SciTech Connect

We present sublinear-time (randomized) algorithms for finding simple cycles of length at least k {ge} 3 and tree-minors in bounded-degree graphs. The complexity of these algorithms is related to the distance of the graph from being C{sub k}-minor-free (resp., free from having the corresponding tree-minor). In particular, if the graph is far (i.e., {Omega}(1)-far) from being cycle-free, i.e. if one has to delete a constant fraction of edges to make it cycle-free, then the algorithm finds a cycle of polylogarithmic length in time {tilde O}({radical}N), where N denotes the number of vertices. This time complexity is optimal up to polylogarithmic factors. The foregoing results are the outcome of our study of the complexity of one-sided error property testing algorithms in the bounded-degree graphs model. For example, we show that cycle-freeness of N-vertex graphs can be tested with one-sided error within time complexity {tilde O}(poly(1/{epsilon}) {center_dot} {radical}N). This matches the known {Omega}({radical}N) query lower bound, and contrasts with the fact that any minor-free property admits a two-sided error tester of query complexity that only depends on the proximity parameter {epsilon}. For any constant k {ge} 3, we extend this result to testing whether the input graph has a simple cycle of length at least k. On the other hand, for any fixed tree T, we show that T -minor-freeness has a one-sided error tester of query complexity that only depends on the proximity parameter {epsilon}. Our algorithm for finding cycles in bounded-degree graphs extends to general graphs, where distances are measured with respect to the actual number of edges. Such an extension is not possible with respect to finding tree-minors in o({radical}N) complexity.

Can incentive regulation improve utility performance. The inherent danger of a simple answer  

SciTech Connect

US electric utilities face fewer incentives for efficient performance than nonregulated firms that operate in competitive markets, so regulators have traditionally relied on regulatory lag and a scrutiny of costs and management procedures. Characterizing the incentive programs which have been implemented by many state regulatory commissions as misguided, the author identifies an alternative adjustment mechanism with a potential for more effective promotion of utility performance improvements. The automatic rate adjustment mechanism (ARAM) links adjustments to cost elements recovered in a utility's rates to changes in external cost indexes for those cost elements. Ratepayers and utility shareholders would be better served by a regulatory scheme that relies on market forces, not shadow managements, to ensure efficient performance.

Managed Pressure Drilling Candidate Selection  

E-Print Network (OSTI)

Managed Pressure Drilling now at the pinnacle of the 'Oil Well Drilling' evolution tree, has itself been coined in 2003. It is an umbrella term for a few new drilling techniques and some preexisting drilling techniques, all of them aiming to solve several drilling problems, including non-productive time and/or drilling flat time issues. These techniques, now sub-classifications of Managed Pressure Drilling, are referred to as 'Variations' and 'Methods' of Managed Pressure Drilling. Although using Managed Pressure Drilling for drilling wells has several benefits, not all wells that seem a potential candidate for Managed Pressure Drilling, need Managed Pressure Drilling. The drilling industry has numerous simulators and software models to perform drilling hydraulics calculations and simulations. Most of them are designed for conventional well hydraulics, while some can perform Underbalanced Drilling calculations, and a select few can perform Managed Pressure Drilling calculations. Most of the few available Managed Pressure Drilling models are modified Underbalanced Drilling versions that fit Managed Pressure Drilling needs. However, none of them focus on Managed Pressure Drilling and its candidate selection alone. An 'Managed Pressure Drilling Candidate Selection Model and software' that can act as a preliminary screen to determine the utility of Managed Pressure Drilling for potential candidate wells are developed as a part of this research dissertation. The model and a flow diagram identify the key steps in candidate selection. The software performs the basic hydraulic calculations and provides useful results in the form of tables, plots and graphs that would help in making better engineering decisions. An additional Managed Pressure Drilling worldwide wells database with basic information on a few Managed Pressure Drilling projects has also been compiled that can act as a basic guide on the Managed Pressure Drilling variation and project frequencies and aid in Managed Pressure Drilling candidate selection.

Environmental enchancement using short-rotation tree crops: research results and directions  

DOE Green Energy (OSTI)

Short-rotation woody crops (SRWC) and perennial grasses used as biomass feedstocks for energy and fiber can provide multiple economic and environmental benefits. Site-specific environmental studies are providing information needed to help evaluate the economic and environmental impacts of biomass production at both local and regional scales. Erosion and chemical movement from an annual row crop, switchgrass, and tree crop with and without a groundcover are being compared in the Southeast. Studies of SRWC productivity on the South Carolina coastal plain are comparing surface and subsurface movement of chemicals applied under different fertilization and irrigation regimes, and addressing use of mill and agricultural residues to enhance crop production. Results are helping to assess the effects of biomass crops produced on different principal soil types and to match tree species with appropriate sites to maximize productivity and minimize environmental impacts. Studies are comparing wildlife use of biomass crops to row crops, grasslands, and natural forests. Results to date show that SRWCs support greater bird diversity than row crops, but less than natural forests; switchgrass plantings extend habitat for grasslands birds. Collaboration with an industrial partner on diverse SRWC plantings in the Southeast is addressing the relationship between plantings of different acreage, age, tree species, and landscape context and breeding bird use. Information from wildlife diversity, water, and soil quality studies can be used by the Biofuels Feedstock Development Program (BFDP), researchers, producers, and industry to identify management strategies to maintain productivity While enhancing the environment.

Answer. Southwestern's vegetation management goals are to promote safety, provide for main- tenance access, and ensure electric system reliability. Trees or other vegetation near a trans- mission line can conduct electricity and increase the chance of unintentional contact with people and pets. If electricity flows through a tree to the ground, that tree essentially becomes "electrified," and anyone touching that tree could sustain serious injury, even death, as electricity seeks a path to ground. Additionally, as the operator of nearly 1,400 miles

Waste analysis plan for 222-S dangerous and mixed waste storage area  

Science Conference Proceedings (OSTI)

The 222-S Laboratory Complex, in the southeast corner of the 200 West Area, consists of the 222-S Laboratory, the 222-SA Standards Laboratory, and several ancillary facilities. Currently, 222-S Laboratory activities are in supporting efforts to characterize the waste stored in the 200 Areas single shell and double shell tanks. Besides this work, the laboratory also provides analytical services for waste-management processing plants, Tank Farms, B Plant, 242-A Evaporator Facility, Plutonium-Uranium Extraction Plant, Plutonium Finishing Plant, Uranium-Oxide Plant, Waste Encapsulation Storage Facility, environmental monitoring and surveillance programs, and activities involving essential materials and research and development. One part of the 222-SA Laboratory prepares nonradioactive standards for the 200 Area laboratories. The other section of the laboratory is used for cold (nonradioactive) process development work and standards preparation. The 219-S Waste Handling Facility has three storage tanks in which liquid acid waste from 222-S can be received, stored temporarily, and neutralized. From this facility, neutralized waste, containing radionuclides, is transferred to the Tank Farms. A 700-gallon sodium-hydroxide supply tank is also located in this facility. This plan provides the methods used to meet the acceptance criteria required by the 204-AR Waste Receiving Facility.

Development of a computer-aided fault tree synthesis methodology for quantitative risk analysis in the chemical process industry  

E-Print Network (OSTI)

There has been growing public concern regarding the threat to people and environment from industrial activities, thus more rigorous regulations. The investigation of almost all the major accidents shows that we could have avoided those tragedies with effective risk analysis and safety management programs. High-quality risk analysis is absolutely necessary for sustainable development. As a powerful and systematic tool, fault tree analysis (FTA) has been adapted to the particular need of chemical process quantitative risk analysis (CPQRA) and found great applications. However, the application of FTA in the chemical process industry (CPI) is limited. One major barrier is the manual synthesis of fault trees. It requires a thorough understanding of the process and is vulnerable to individual subjectivity. The quality of FTA can be highly subjective and variable. The availability of a computer-based FTA methodology will greatly benefit the CPI. The primary objective of this research is to develop a computer-aided fault tree synthesis methodology for CPQRA. The central idea is to capture the cause-and-effect logic around each item of equipment directly into mini fault trees. Special fault tree models have been developed to manage special features. Fault trees created by this method are expected to be concise. A prototype computer program is provided to illustrate the methodology. Ideally, FTA can be standardized through a computer package that reads information contained in process block diagrams and provides automatic aids to assist engineers in generating and analyzing fault trees. Another important issue with regard to QRA is the large uncertainty associated with available failure rate data. In the CPI, the ranges of failure rates observed could be quite wide. Traditional reliability studies using point values of failure rates may result in misleading conclusions. This dissertation discusses the uncertainty with failure rate data and proposes a procedure to deal with data uncertainty in determining safety integrity level (SIL) for a safety instrumented system (SIS). Efforts must be carried out to obtain more accurate values of those data that might actually impact the estimation of SIL. This procedure guides process hazard analysts toward a more accurate SIL estimation and avoids misleading results due to data uncertainty.

Hanford double shell tank corrosion monitoring instrument trees  

Science Conference Proceedings (OSTI)

High-level nuclear wastes at the Hanford site are stored underground in carbon steel double-shell and single-shell tanks - (DSTs and SSTS). Westinghouse Hanford Company is considering installation of a prototype corrosion monitoring instrument tree in at least one DST in the summer of 1995. The instrument tree will have the ability to detect and discriminate between uniform corrosion, stress corrosion cracking (SCC), and pitting. Additional instrument trees will follow in later years. Proof-of-technology testing is currently underway for the use of commercially available electric field pattern (EFP) analysis and electrochemical noise (EN) corrosion monitoring equipment. Creative use and combinations of other existing technologies is also being considered. Successful demonstration of these technologies will be followed by the development of a Hanford specific instrument tree. The first instrument tree will incorporate one of these technologies. Subsequent trees may include both technologies, as well as a more standard assembly of corrosion coupons. Successful development of these trees will allow their application to single shell tanks and the transfer of technology to other U.S. Department of Energy (DOE) sites.

Woody biomass potential of the Chinese tallow tree  

Science Conference Proceedings (OSTI)

The Chinese tallow tree (Sapium sebiferum Roxb.) ia a rapid-growing species that has become naturalized along the Gulf and southern Atlantic coasts. The tree is particularly well adapted to poorly-drained and saline soils. Chinese tallow seedlings planted at 2' x 2' spacing produced over 5 dry tons of biomass/acre at the end of the second growing season, while the biomass accumulation on coppiced plots was more than 7 dry tons/acre at the end of the second year. The Chinese tallow tree has considerable promise as a woody biomass species in the southern coastal regions of the United States. 4 references, 1 figure, 4 tables.

Surety theoretics: The forest or the trees?  

Science Conference Proceedings (OSTI)

Periodically one needs to re-examine the objectives and the efforts associated with a field of study. In the case of surety which comprises, safety, security and reliability one needs to be sure that theoretical efforts support the needs of systems and design engineers in satisfying stakeholder requirements. The current focus in the surety areas does not appear to address the theoretical foundations needed by the systems engineer. Examination of papers and abstracts demonstrate significant effort along the lines of thermal hydraulics, chemistry, structural response, control theory, etc. which are analytical disciplines which provide support for a surety theoretic but do not constitute a theoretic. The representations currently employed, fault trees etc., define static representations of a system, not the dynamic representation characteristic of response in abnormal, hostile or under degrading conditions. Current methodologies would require a semi-infinite set of scenarios to be examined before a system could be certified as satisfying a surety requirement. The elements that are required of a surety theoretic must include: (1) a dynamic representation of the system; (2) the ability to automatically identify terminal states of the system; and (3) determine the probabilities of specified terminal states under dynamic conditions. This paper examines the requirements of a surety theoretic that will support the efforts of the design and development engineer. Speculations then follow on technologies that might provide the theoretical and support foundations needed by the systems engineering community to form a robust surety analysis and design environment.

Fiber, fuel and food from whole-tree chips  

Science Conference Proceedings (OSTI)

Future shortages of fiber, fuel, and food are predicted. Because forests are renewable, they have the potential of solving long and short-term shortages if each tree is more completely utilized. The combined vacuum-airlift and steaming-compression debarking process developed by the USDA Forest Service segregates whole-tree chips into foliage, wood chips, bark, and fines at an estimated processing cost of $5.14 per oven-dry debarked metric ton. Several alternatives are available for utilizing the wood chips, bark, and foliage. The value of the bark as a fuel and the folage as an animal feed supplement more than covers the cost of upgrading the whole-tree chips. Beneficiation of whole-tree chips coupled with intergrated utilization should improve chip quality, reduce costs, and help the pulp and paper industry become energy self-sufficient. (Refs. 34).

Hanford double shell tank corrosion monitoring instrument tree prototype  

Science Conference Proceedings (OSTI)

High-level nuclear wastes at the Hanford site are stored underground in carbon steel double-shell and single-shell tanks (DSTs and SSTs). The installation of a prototype corrosion monitoring instrument tree into DST 241-A-101 was completed in December 1995. The instrument tree has the ability to detect and discriminate between uniform corrosion, pitting, and stress corrosion cracking (SCC) through the use of electrochemical noise measurements and a unique stressed element, three-electrode probe. The tree itself is constructed of AISI 304L stainless steel (UNS S30403), with probes in the vapor space, vapor/liquid interface and liquid. Successful development of these trees will allow their application to single shell tanks and the transfer of technology to other US Department of Energy (DOE) sites. Keywords: Hanford, radioactive waste, high-level waste tanks, electrochemical noise, probes, double-shell tanks, single-shell tanks, corrosion.

A Performance Comparison of Tree and Ring Topologies in Distributed System  

Science Conference Proceedings (OSTI)

A distributed system is a collection of computers that are connected via a communication network. Distributed systems have become commonplace due to the wide availability of low-cost, high performance computers and network devices. However, the management infrastructure often does not scale well when distributed systems get very large. Some of the considerations in building a distributed system are the choice of the network topology and the method used to construct the distributed system so as to optimize the scalability and reliability of the system, lower the cost of linking nodes together and minimize the message delay in transmission, and simplify system resource management. We have developed a new distributed management system that is able to handle the dynamic increase of system size, detect and recover the unexpected failure of system services, and manage system resources. The topologies used in the system are the tree-structured network and the ring-structured network. This thesis presents the research background, system components, design, implementation, experiment results and the conclusions of our work. The thesis is organized as follows: the research background is presented in chapter 1. Chapter 2 describes the system components, including the different node types and different connection types used in the system. In chapter 3, we describe the message types and message formats in the system. We discuss the system design and implementation in chapter 4. In chapter 5, we present the test environment and results, Finally, we conclude with a summary and describe our future work in chapter 6.

Accident Fault Trees for Defense Waste Processing Facility  

Science Conference Proceedings (OSTI)

The purpose of this report is to document fault tree analyses which have been completed for the Defense Waste Processing Facility (DWPF) safety analysis. Logic models for equipment failures and human error combinations that could lead to flammable gas explosions in various process tanks, or failure of critical support systems were developed for internal initiating events and for earthquakes. These fault trees provide frequency estimates for support systems failures and accidents that could lead to radioactive and hazardous chemical releases both on-site and off-site. Top event frequency results from these fault trees will be used in further APET analyses to calculate accident risk associated with DWPF facility operations. This report lists and explains important underlying assumptions, provides references for failure data sources, and briefly describes the fault tree method used. Specific commitments from DWPF to provide new procedural/administrative controls or system design changes are listed in the ''Facility Commitments'' section. The purpose of the ''Assumptions'' section is to clarify the basis for fault tree modeling, and is not necessarily a list of items required to be protected by Technical Safety Requirements (TSRs).

Attack Tree Based Information Security Risk Assessment Method Integrating Enterprise Objectives with Vulnerabilities IAJIT First Online Publication  

E-Print Network (OSTI)

Abstract: In order to perform the analysis and mitigation efforts related with the Information Security risks there exists quantitative and qualitative approaches, but the most critical shortcoming of these methods is the fact that the outcome mainly addresses the needs and priorities of the technical community rather than the management. For the enterprise management, this information is essentially required as a decision making aid for the asset allocation and the prioritization of mitigation efforts. So ideally the outcome of an information security risk method must be in synchronization with the enterprise objectives to act as a useful decision tool for the management. Also in the modelling of the threat domain, attack trees are frequently utilized. However the execution of attack tree modelling is costly from the effort and timing requirements and also has inherent scalability issues. So within this article our design-science research based work on an information security risk assessment method that addresses these two issues of enterprise objective inclusion and model scalability will be outlined.

Tappable Pine Trees: Commercial Production of Terpene Biofuels in Pine  

Science Conference Proceedings (OSTI)

PETRO Project: The University of Florida is working to increase the amount of turpentine in harvested pine from 4% to 20% of its dry weight. While enhanced feedstocks for biofuels have generally focused on fuel production from leafy plants and grasses, the University of Florida is experimenting with enhancing fuel production in a species of pine that is currently used in the paper pulping industry. Pine trees naturally produce around 3-5% terpene content in the woodterpenes are the energy-dense fuel molecules that are the predominant components of turpentine. The team aims to increase the terpene storage potential and production capacity while improving the terpene composition to a point at which the trees could be tapped while alive, like sugar maples. Growth and production from these trees will take years, but this pioneering technology could have significant impact in making available an economical and domestic source of aviation and diesel biofuels.

USE OF THE SPATIAL KD-TREE IN COMPUTATIONAL PHYSICSAPPLICATIONS  

Science Conference Proceedings (OSTI)

The need to perform spatial queries and searches is commonly encountered within the field of computational physics. The development of applications ranging from scientific visualization to finite element analysis requires efficient methods of locating domain objects relative to general locations in space. Much of the time, it is possible to form and maintain spatial relationships between objects either explicitly or by using relative motion constraints as the application evolves in time. Occasionally, either due to unpredictable relative motion or the lack of state information, an application must perform a general search (or ordering) of geometric objects without any explicit spatial relationship information as a basis. If previous state information involving domain geometric objects is not available, it is typically an involved and time consuming process to create object adjacency information or to order the objects in space. Further, as the number of objects and the spatial dimension of the problem domain is increased, the time required to search increases greatly. This paper proposes an implementation of a spatial k-d tree (skD-tree) for use by various applications when a general domain search is required. The skD-tree proposed in this paper is a spatial access method where successive tree levels are split along different dimensions. Objects are indexed by their centroid, and the minimum bounding box of objects in a node are stored in the tree node. The paper focuses on a discussion of efficient and practical algorithms for multidimensional spatial data structures for fast spatial query processing. These functions include the construction of a skD-tree of geometric objects, intersection query, containment query, and nearest neighbor query operations.

Development and Validation of Sterility Systems for Trees  

SciTech Connect

The overall goal of this project was to develop and validate sterility systems in poplar with the ultimate goal of fulfilling the basic requirements for commercial use. For this, sterility must be complete and stable over multiple growing seasons, cause no detrimental effects on vegetative growth, and successful transformation events must be identifiable via molecular tests when trees are still juvenile. Because of the inherent difficulties in achieving and demonstrating complete sterility in trees, our approach was to study alternate sterility systems in Arabidopsis and/or early-flowering tree systems. The public benefit from this work is the capacity for containment of genes or exotic forms of trees so they can be of benefit for industry for production of wood, energy, and renewable products, while having minimal impact on wild populations of trees. We tested three methods for engineering sterility: dominant negative mutant (DNM) proteins, floral tissue ablation, and RNA interference (RNAi) to suppress the expression of several floral regulatory genes. The ultimate goal of this work was to produce a number of transgenic poplars that could be outplanted to enable future assessments of the effectiveness of these transgenic sterility methods. Our attempts to produce ablation constructs that did not interfere with tree health were partially successful. Using the poplar LEAFY gene promoter and the barnase/barstar system, we were able to regenerate plants that grew well in the greenhouse, but they showed poor health in the field. Four of seven DNM genes tested were considered promising enough, based on results in Arabidopsis, to produce transgenic poplars. Single, double, and triple RNAi genes were produced and transformed into poplar. Over all, we produced 1,964 PCR-confirmed transgenic events with 19 different kinds of sterility genes and several kinds of control genes. We propagated 5,640, 6,820, and 7,055 trees for each of three test poplar genotypes, and field plantings were begun in Spring of 2003 and will be finished in Spring 2007. Continued field studies and monitoring will be required to establish if any of the approaches we have taken will prove to be safe for tree health, stable, and provide reliable containment.

A Tree Swaying in a Turbulent Wind: A Scaling Analysis  

E-Print Network (OSTI)

A tentative scaling theory is presented of a tree swaying in a turbulent wind. It is argued that the turbulence of the air within the crown is in the inertial regime, An eddy causes a dynamic bending response of the branches according to a time criterion. The resulting expression for the penetration depth of the wind yields an exponent which is in agreement with that pertaining to the morphology of the tree branches. An energy criterion shows that the dynamics of the branches is basically passive. The possibility of hydrodynamic screening by the leaves is discussed.

Witness trees in the Moser-Tardos algorithmic Lovsz Local Lemma and Penrose trees in the hard core lattice gas  

E-Print Network (OSTI)

We point out a close connection between the Moser-Tardos algorithmic version of the Lov\\'asz Local Lemma, a central tool in probabilistic combinatorics, and the cluster expansion of the hard core lattice gas in statistical mechanics. We show that the notion of witness trees given by Moser and Tardos is essentially coincident with that of Penrose trees in the Cluster expansion scheme of the hard core gas. Such an identification implies that the Moser Tardos algorithm is successful in a polynomial time if the Cluster expansion converges.

Fault trees for decision making in systems analysis  

SciTech Connect

The application of fault tree analysis (FTA) to system safety and reliability is presented within the framework of system safety analysis. The concepts and techniques involved in manual and automated fault tree construction are described and their differences noted. The theory of mathematical reliability pertinent to FTA is presented with emphasis on engineering applications. An outline of the quantitative reliability techniques of the Reactor Safety Study is given. Concepts of probabilistic importance are presented within the fault tree framework and applied to the areas of system design, diagnosis and simulation. The computer code IMPORTANCE ranks basic events and cut sets according to a sensitivity analysis. A useful feature of the IMPORTANCE code is that it can accept relative failure data as input. The output of the IMPORTANCE code can assist an analyst in finding weaknesses in system design and operation, suggest the most optimal course of system upgrade, and determine the optimal location of sensors within a system. A general simulation model of system failure in terms of fault tree logic is described. The model is intended for efficient diagnosis of the causes of system failure in the event of a system breakdown. It can also be used to assist an operator in making decisions under a time constraint regarding the future course of operations. The model is well suited for computer implementation. New results incorporated in the simulation model include an algorithm to generate repair checklists on the basis of fault tree logic and a one-step-ahead optimization procedure that minimizes the expected time to diagnose system failure.

Composition of Management System for Smart Homes  

E-Print Network (OSTI)

The paper addresses modular hierarchical design (composition) of a management system for smart homes. The management system consists of security subsystem (access control, alarm control), comfort subsystem (temperature, etc.), intelligence subsystem (multimedia, houseware). The design solving process is based on Hierarchical Morphological Multicriteria Design (HMMD) approach: (1) design of a tree-like system model, (2) generation of design alternatives for leaf nodes of the system model, (3) Bottom-Up process: (i) multicriteria selection of design alternatives for system parts/components and (ii) composing the selected alternatives into a resultant combination (while taking into account ordinal quality of the alternatives above and their compatibility). A realistic numerical example illustrates the design process of a management system for smart homes.

Finding genes in DNA using decision trees and dynamic programming  

E-Print Network (OSTI)

{ salz berg,xchendhndrsn}:~cs.jhu.edu,kewf~gdb.org This study demonstrates the use of decision tree classifiers as the basis for a general gene-finding system. The system uses a dynamic programming algorithm that. finds the optimal segmentation of a DNA sequence into coding and noncoding regions (exons and introits).]he optimality property is dependent oll a separate scoring function that takes a subsequence and assigns to it a score reflecting the probability that the sequence is an exon. In this study, the scoring functions were sets of decision trees and rules that were combined to give the probability estimate. Experimental results on a newly collected database of human DNA sequences are encouraging, and some new observations about the structure of classifiers for tile gene-finding problem have emerged from this study. We also provide descriptions of a new probability chain model that produces very accurate filters to find donor and acceptor sites.

Transfer current and pattern fields in spanning trees  

E-Print Network (OSTI)

When a simply connected domain $D\\subset{\\mathbb{R}}^d$ ($d\\ge 2$) is approximated in a "good" way by embedded connected weighted graphs, we prove that the transfer current matrix (defined on the edges of the graph viewed as an electrical network) converges, up to a local weight factor, to the differential of Green's function on $D$. This observation implies that properly rescaled correlations of the spanning tree model and correlations of minimal subconfigurations in the abelian sandpile model have a universal and conformally covariant limit. We further show that, on a periodic approximation of the domain, all pattern fields of the spanning tree model, as well as the minimal-pattern (e.g. zero-height) fields of the sandpile, converge weakly in distribution to Gaussian white noise.

Parallel Algorithms for Graph Optimization using Tree Decompositions  

SciTech Connect

Although many $\\cal{NP}$-hard graph optimization problems can be solved in polynomial time on graphs of bounded tree-width, the adoption of these techniques into mainstream scientific computation has been limited due to the high memory requirements of the necessary dynamic programming tables and excessive runtimes of sequential implementations. This work addresses both challenges by proposing a set of new parallel algorithms for all steps of a tree decomposition-based approach to solve the maximum weighted independent set problem. A hybrid OpenMP/MPI implementation includes a highly scalable parallel dynamic programming algorithm leveraging the MADNESS task-based runtime, and computational results demonstrate scaling. This work enables a significant expansion of the scale of graphs on which exact solutions to maximum weighted independent set can be obtained, and forms a framework for solving additional graph optimization problems with similar techniques.

JBIG2 Symbol Dictionary Design Based on Minimum Spanning Trees  

E-Print Network (OSTI)

The JBIG2 standard is a very flexible bi-level image coding strategy based on pattern matching. The encoder collects a set of symbols in a dictionary and encodes a page by reference to the dictionary symbols. JBIG2 allows the encoder to view all symbols and choose a good set for the dictionary. In this paper, we examine the bit rate trade-off that arises in choosing different dictionary sizes. In particular, we propose a suboptimal dictionary design technique based on minimum spanning trees. This technique gives competitive compression ratios and allows us to specify the dictionary size almost arbitrarily, thus providing a way to study the bit rate trade-off problem in detail. Keywords: JBIG2, Text image compression, Symbol dictionary, Minimum spanning tree 1

On the Construction of WiMax Mesh Tree  

E-Print Network (OSTI)

Abstract The IEEE 802.16 protocol, also known as WiMAX, has been designed to support long-range communications with high bitrates, using two operation modes: Point-to-Multi-Point (PMP) and Mesh. In the mesh mode, Subscriber Stations (SSs) can directly communicate with each other, thus forming a tree, and can be used to forward others data packets in a multihop fashion. On the contrary, in the PMP mode only one hop communication toward the Base Station (BS) is allowed. In this paper, we investigate the performance of the mesh mode by proposing an algorithm for constructing the WiMAX mesh tree. Our algorithm increases routes effective throughput by splitting long links into multiple shorter ones. We show through simulations that this approach leads to improving the throughput capacity of WiMAX-based wireless mesh networks. Index Terms WiMAX, wireless mesh networks. I.

Parallel TreeSPH: A Tool for Galaxy Formation  

E-Print Network (OSTI)

We describe a new implementation of a parallel Tree-SPH code with the aim to simulate Galaxy Formation and Evolution. The code has been parallelized using SHMEM, a Cray proprietary library to handle communications between the 256 processors of the Silicon Graphics T3E massively parallel supercomputer hosted by the Cineca Super-computing Center (Bologna, Italy). The code combines the Smoothed Particle Hydrodynamics (SPH) method to solve hydro-dynamical equations with the popular Barnes and Hut (1986) tree-code to perform gravity calculation with a $N \\times logN$ scaling, and it is based on the scalar Tree-SPH code developed by Carraro et al (1998)[MNRAS 297, 1021]. Parallelization is achieved distributing particles along processors according to a work-load criterium. Benchmarks, in terms of load-balance and scalability, of the code are analised and critically discussed against the adiabatic collapse of an isothermal gas sphere test using $2 \\times 10^{4}$ particles on 8 processors. The code results balanced at more than 95% level. Increasing the number of processors, the load balance sligthly worsens. The deviation from perfect scalability at increasing number of processors is negligible up to 64 processors. Additionally we have incorporated radiative cooling, star formation, feed-back and an algorithm to follow the chemical enrichment of the interstellar medium.

The Rotor-Router Model on Regular Trees  

E-Print Network (OSTI)

The rotor-router model is a deterministic analogue of random walk. It can be used to define a deterministic growth model analogous to internal DLA. We show that if the initial rotor configuration is acyclic, then the set of occupied sites for rotor-router aggregation on an infinite regular tree is a perfect ball whenever it can be. This is proved by defining the rotor-router group of a graph, which we show is isomorphic to the sandpile group. We also address the question of recurrence and transience: We give two rotor configurations on the infinite ternary tree, one for which chips exactly alternate escaping to infinity with returning to the origin, and one for which every chip returns to the origin. We also characterize the possible "escape sequences" for the ternary tree, that is, binary words $a_1 ... a_n$ for which there exists a rotor configuration so that the $k$-th chip escapes to infinity if and only if $a_k=1$.

Identification of Pseudomonas aeruginosa via a poplar tree model  

E-Print Network (OSTI)

Differential gene expression of P. aeruginosa in a rhizosphere biofilm on poplar tree roots was examined in order to identify new virulence factors from this human pathogen. Changes in gene expression for poplar trees contacted with P. aeruginosa was examined as well to identify the response of poplar roots to P. aeruginosa infection. This is the first study of the whole-transcriptome analysis of P. aeruginosa on a plant tree root. The 20 most highly-induced genes of P. aeruginosa were examined for their role in biofilm formation, rhizosphere colonization, barley germination, and poplar tree killing assays. Seven previously uncharacterized virulence genes (PA1385, PA2146, PA2462, PA2463, PA2663, PA4150, and PA4295) were identified. The role of PA2663, a hypothetical protein discovered in the microarrays of P. aeruginosa while killing poplar trees, was examined in further detail. Expression of PA2663 protein increases biofilm formation in P. aeruginosa PAO1 drastically. By complementing the PA2663 mutation in trans and by studying with DNA microarrays and RT-PCR the PA2663 mutant vs. the wild-type strain, PA2663 was confirmed to be related to biofilm formation and was found that it is the first protein to control the psl operon in P. aeruginosa PAO1. Furthermore, PA2663 protein increases pyoverdine synthesis and quorum sensing (QS)- regulated phenotypes. A biofilm formation-related hypothetical protein, PA0939, was identified in this study. The effects of indole and 7-hydroxyindole on P. aeruginosa virulence factors were also examined for the first time. Indole and 7HI repressed expression of mexGHI-opmD multidrug efflux pump genes and genes involved in synthesis of QS-regulated virulence factors (pyocyanin, rhamnolipid, PQS, and pyoverdine production). In addition, the effects of an anti-cancer uracil analog, 5-fluorouracil (5-FU) on P. aeruginosa virulence factors and E. coli K-12 biofilm formation were examined. 5-FU repressed biofilm formation, abolished quorum-sensing phenotypes, and reduced virulence in P. aeruginosa. DNA microarray and biofilm studies with 5-FU in E. coli revealed that 5-FU controls biofilm formation through the AriR protein in E. coli K-12 strain. The effects of lsrR and lsrK mutations on E. coli biofilm formation were also examined by flow cell experiments.

MANAGEMENT SUMMARY  

E-Print Network (OSTI)

need to effectively manage business performance. This has never been more true than in todays complex, highly regulated and confusing business environment which requires better decisions and improved execution now! In spite of the billions of dollars invested in infor-mation technology to address these challenges, managers and executives in many organizations still make key decisions underpinned by their own personal versions of documents and spread-sheets. Their organization struggles to provide a seamless flow of trusted information between customers, suppliers and their employees. The result is that most organizations cannot provide their people with the right information at the right time, and in attempting to do so are committing significant resources to compiling and auditing numbers instead of using them to inform the business. Consequently, they are far more reac-tive than proactive and ultimately they are not efficiently and effectively managing their current and future performance. Leading organizations are investing in managing information and developing predictive insights to drive sustainable business results. These com-panies have become masters in Performance Management- going beyond mere users of business intelligence to become the Intelligent Enterprises. ...a new breed of company is upping the stakes....have dominated their fields by deploy-ing industrial-strength analytics across a wide variety of activities. In essence, they are trans-forming their organiza-tions into armies of killer apps and crunching their way to victory.

Additionaly we have incorporated radiative cooling, star formation, feed-back from SNae of type II and Ia, stellar winds and UV flux from massive stars, and an algorithm to follow the chemical enrichment of the inter-stellar medium. Simulations with some of these ingredients are also presented.

The authors discuss the strengthening of Christmas trees for service conditions, in particular, the method of plasma spraying of the sealing surfaces of the gates of the valves with hard corrosion resistant alloys. Most frequently, cobalt- (stellite), nickel- (colmonoy), and iron-base alloys are used for surfacing. A plan is shown of the area for plasma surfacing in one of the petroleum machinery plants. It is found that the hardening of the sealing surface of gate valve parts by plasma powder surfacing with self-fluxing nickel alloys increases the reliability and life of well-head equipment.

Supplement Analysis for the Transmission System Vegetation Management Program FEIS DOE/EIS-0285/SA-08  

Science Conference Proceedings (OSTI)

Clearing C-trees along the south side of the right-of-way. This project meets the standards and guidelines for the Transmission System Vegetation Management Program Final Environmental Impact Statement (FEIS) and Record of Decision (ROD). The project involves controlling all tall growing trees (C-Trees) within the right-of-way. All work is to be done on the south side of centerline. Target vegetation is the tall growing Firs along the edge of the ROW, all of which is located within the back yards of the property owners along the right-of-way. The density of vegetation is low and consists of C-Trees located within backyards, with the branches growing towards the lines. Due to lack of access and past verbal agreements with the landowners, permission/agreement has been difficult to obtain from the property owners. Permission has now been obtained to remove the C-Trees within their back yards which, will soon be a hazard to our transmission line facility. We are working with the landowners to get them to plant low growing scrubs and ornamentals within the right-of-way and adjacent to the right-of-way. A follow up herbicide treatment is not planned because the trees being cut will not re-sprout. This right-of-way or project area is on a three to four year maintenance schedule. Little or no treatment should be required in the immediate future.

Open Access Development of a Methodology to Estimate Biomass from Tree Height Using Airborne Digital Image  

E-Print Network (OSTI)

Copyright 2012 J. Jenitha Ferdinent and Raj Chandar Padmanaban. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract Globally biomass is becoming imperative for function such as climate change, combined heat and power generation. The biomass energy is gaining significance as a source of clean heat for domestic heating and community heating applications. Regarding climatic change and global warming, the biomass is being estimated in various ways. By including three dimensions (i.e.) height of a tree or stand height of trees in forest will greatly help in estimation biomass more accurately. Traditionally close range Photogrammetry is used to determine volume and biomass of the tree. However, this method of volume/height of a tree is not feasible in large scale applications and time consuming. Globally researchers are working to estimate this by using either airborne/space borne data. In this project, a methodology to measure tree height in case of single tree or stand height (mean tree height) of an area is developed using airborne digital camera. The height of the tree was first estimated from the airborne digital camera image data. The image taken from Airborne UltraCamD has been used. This image is 23cm X 15cm image size and 20cm resolution. Aerial

Horn, Scott, James L. Hanula, Michael D. Ulyshen, and John C. Kilgo. 2005. Abundance of green tree frogs and insects in artificial canopy gaps in a bottomland hardwood forest. Am. Midl. Nat. 153:321-326. Abstract: We found more green tree frogs (Hyla cinerea) in canopy gaps than in closed canopy forest. Of the 331 green tree frogs observed, 88% were in canopy gaps. Likewise, higher numbers and biomasses of insects were captured in the open gap habitat. Flies were the most commonly collected insect group accounting for 54% of the total capture. These data suggest that one reason green tree frogs were more abundant in canopy gaps was the increased availability of prey and that small canopy gaps provide early successional habitats that are beneficial to green tree frog populations.

Lignin and lignosulfonates -- From the tree to the battery  

Science Conference Proceedings (OSTI)

Lignin is the second most abundant, naturally occurring polymer. It is second only to its partner in the tree, cellulose. The paper-making industry has perfected several ways to economically free the cellulose from nature's glue, the lignin. The different pulping processes yield vastly different lignins. Various wood products, lignins and their derivatives have been used extensively in lead acid batteries. Starting with wood separators used in the early 1920's to specialized lignosulfonates currently used as the organic component of the negative plate expander formulations in lead acid batteries. This paper will give an overview of the two most prevalent routes currently used for pulping by the paper-making industry. This paper will then review the process used by Westvaco Corporation to isolate and modify the resulting lignin. It will conclude with the work done to synthesize and evaluate KRAFTPLEX{trademark}, a new lignosulfonate for use in negative plate expander formulations.

Answer extraction as sequence tagging with tree edit distance  

E-Print Network (OSTI)

Our goal is to extract answers from preretrieved sentences for Question Answering (QA). We construct a linear-chain Conditional Random Field based on pairs of questions and their possible answer sentences, learning the association between questions and answer types. This casts answer extraction as an answer sequence tagging problem for the first time, where knowledge of shared structure between question and source sentence is incorporated through features based on Tree Edit Distance (TED). Our model is free of manually created question and answer templates, fast to run (processing 200 QA pairs per second excluding parsing time), and yields an F1 of 63.3 % on a new public dataset based on prior TREC QA evaluations. The developed system is open-source, and includes an implementation of the TED model that is state of the art in the task of ranking QA pairs. 1

Implicit Renewal Theory and Power Tails on Trees  

E-Print Network (OSTI)

We extend Goldie's (1991) Implicit Renewal Theorem to enable the analysis of recursions on weighted branching trees. We illustrate the developed method by deriving the power tail asymptotics of the distributions of the solutions R to: R =_D sum_{i=1}^N C_i R_i + Q, R =_D max(max_{i=1}^N C_i R_i, Q), and similar recursions, where (Q, N, C_1,..., C_N) is a nonnegative random vector with N in {0, 1, 2, 3, ..., infinity}, and {R_i}_{i >= 1} are iid copies of R, independent of (Q, N, C_1,..., C_N); =_D denotes the equality in distribution.

Managing PCBs  

Science Conference Proceedings (OSTI)

Compliance with Environmental Protection Agency regulations for managing the polychlorinated biphenyls (PCBs) that were widely distributed in electrical equipment will be costly to the utility industry, estimated at over $5 billion over a ten-year period by the Electric Power Research Institute (EPRI). Most of the budget could be needed to identify and reclaim 2.5 million contaminated transformers. Three divisions are coordinating EPRI research efforts with those of other companies and utilities in the areas of detection, destruction, spill cleanup, disposal, and health effects. (DCK)

A DOM tree alignment model for mining parallel data from the Web  

E-Print Network (OSTI)

This paper presents a new web mining scheme for parallel data acquisition. Based on the Document Object Model (DOM), a web page is represented as a DOM tree. Then a DOM tree alignment model is proposed to identify the translationally equivalent texts and hyperlinks between two parallel DOM trees. By tracing the identified parallel hyperlinks, parallel web documents are recursively mined. Compared with previous mining schemes, the benchmarks show that this new mining scheme improves the mining coverage, reduces mining bandwidth, and enhances the quality of mined parallel sentences. 1

A framework for the assessment of severe accident management strategies  

SciTech Connect

Severe accident management can be defined as the use of existing and/or altemative resources, systems and actors to prevent or mitigate a core-melt accident. For each accident sequence and each combination of severe accident management strategies, there may be several options available to the operator, and each involves phenomenological and operational considerations regarding uncertainty. Operational uncertainties include operator, system and instrumentation behavior during an accident. A framework based on decision trees and influence diagrams has been developed which incorporates such criteria as feasibility, effectiveness, and adverse effects, for evaluating potential severe accident management strategies. The framework is also capable of propagating both data and model uncertainty. It is applied to several potential strategies including PWR cavity flooding, BWR drywell flooding, PWR depressurization and PWR feed and bleed.

Summary. This paper is concerned with developing methodological aspects of multivariate Polya trees for density estimation and prediction. A simulation scheme for exploring conditional relationships among variables is developed. To address the issue of partition dependence an outstanding limitation of Polya trees and other partition-based models we develop Randomised Polya Trees. This new framework inherits the structure of Polya trees but jitters partition points and as a result smooths discontinuities in predictive distributions. Some of the theoretical aspects of the new framework are developed, followed by discussion of methodological and computational issues arising in implementation. Examples of data analyses and prediction problems are provided to highlight issues of Bayesian inference in this context, and

Split and Join: Strong Partitions and Universal Steiner Trees for Graphs  

E-Print Network (OSTI)

We study the problem of constructing universal Steiner trees for undirected graphs. Given a graph $G$ and a root node $r$, we seek a single spanning tree $T$ of minimum stretch, where the stretch of $T$ is defined to be the maximum ratio, over all subsets of terminals $X$, of the ratio of the cost of the sub-tree $T_X$ that connects $r$ to $X$ to the cost of an optimal Steiner tree connecting $X$ to $r$. Universal Steiner trees (USTs) are important for data aggregation problems where computing the Steiner tree from scratch for every input instance of terminals is costly, as for example in low energy sensor network applications. We provide a polynomial time UST construction for general graphs with $2^{O(\\sqrt{\\log n})}$-stretch. We also give a polynomial time polylogarithmic-stretch construction for minor-free graphs. One basic building block in our algorithm is a hierarchy of graph partitions, each of which guarantees small strong cluster diameter and bounded local neighbourhood intersections. Our partition h...

An assessment of management practices of wood and wood-related wastes in the urban environment  

DOE Green Energy (OSTI)

The US Environmental Protection Agency estimates that yard waste{sup 1} accounts for approximately 16% of the municipal solid waste (MSW) stream (US EPA, 1994). Until recently, specific data and related information on this component of the (MSW) stream has been limited. The purposes of this study, phase two of the three-phase assessment of urban wood waste issues, are to assess and describe current alternatives to landfills for urban wood waste management; provide guidance on the management of urban wood waste to organizations that produce or manage wood waste; and clarify state regulatory and policy positions affecting these organizations. For this study, urban wood waste is defined as solid waste generated by tree and landscape maintenance services (public and private). Urban wood waste includes the following materials: unchipped mixed wood, unchipped logs, and unchipped tops and brush; clearing and grubbing waste; fall leaves and grass clippings; and chips and whole stumps. Construction and demolition debris and consumer-generated yard waste are not included in this study. Generators of urban wood waste include various organizations; municipal, county, and commercial tree care divisions; nurseries, orchards, and golf courses; municipal park and recreation departments; and electric and telephone utility power line maintenance, excavator and land clearance, and landscape organizations. (1) US EPA defines yard waste as ''yard trimmings'' which includes ''grass, leaves and tree brush trimmings from residential, institutional, and commercial sources.''

The X-tree: An Index Structure for High-Dimensional Data  

E-Print Network (OSTI)

In this paper, we propose a new method for indexing large amounts of point and spatial data in highdimensional space. An analysis shows that index structures such as the R*-tree are not adequate for indexing high-dimensional data sets. The major problem of R-tree-based index structures is the overlap of the bounding boxes in the directory, which increases with growing dimension. To avoid this problem, we introduce a new organization of the directory which uses a split algorithm minimizing overlap and additionally utilizes the concept of supernodes. The basic idea of overlap-minimizing split and supernodes is to keep the directory as hierarchical as possible, and at the same time to avoid splits in the directory that would result in high overlap. Our experiments show that for high-dimensional data, the X-tree outperforms the well-known R*-tree and the TV-tree by up to two orders of magnitude. 1. Introduction In many applications, indexing of high-dimensional data has become increasingl...

Fault tree analysis of the EBR-II reactor shutdown system  

SciTech Connect

As part of the level I Probabilistic Risk Assessment of the Experimental Breeder Reactor II (EBR-II), detailed fault trees for the reactor shutdown system are developed. Fault tree analysis is performed for two classes of transient events that are of particular importance to EBR-II operation: loss-of-flow and transient-overpower. In all parts of EBR-II reactor shutdown system, redundancy has been utilized in order to reduce scram failure probability. Therefore, heavy emphasis is placed in the fault trees on the common cause failures (CCFs) among similar mechanical components of the control and safety rods and among similar electrical components in redundant detection channels and shutdown strings. Generic beta-factors that cover all types of similar components and reflect redundancy level are used to model the CCFs. Human errors are addressed in the fault trees in two major areas: errors that would prevent the automatic scram channels from detecting the abnormal events and errors that would prevent utilization of the manual scram capability. The fault tree analysis of the EBR-II shutdown system has provided not only a systematic process for calculating the probabilities of system failures but also useful insights into the system and how its elements interact during transient events that require shutdown.

Correlations and periodicities in Himalayan tree ring widths and temperature anomalies through wavelets  

E-Print Network (OSTI)

We have studied periodicities and correlation properties of tree ring width chronology of deodar tree from Joshimath (1584 - 1999 years) and Uttarkashi (1500 - 2002 years) in the western Himalayas and the pre-monsoon (March-April-May) temperature anomalies (1876 - 2003) relative to 1961 -1990 mean, through wavelet analysis. Periodic behavior is observed in the tree ring chronology with periodicity in the form 11, 22, and 42 years. The analysis of the self-similar nature reveals long-range correlation with a Hurst exponent, $H >0.5$. These are anti-correlated with the temperature anomalies. An interesting inversion behavior is observed around the year 1750. The power spectral analysis of the time series corroborate the results of wavelet method.

Food and petroleum resources from the Chinese tallow tree. Phase 2. Final report  

Science Conference Proceedings (OSTI)

The general data base on the biology of the Chinese tallow tree (sapium sebiferum (L.) Roxb.) was expanded and specific data regarding its genetics and ecology were developed. A morphmetric study and a genetic characterization of the tree was made via isozyme electrophoresis as a basis for a crop-improvement program. Both flowers and seeds were analyzed electrophoretically. Observations were begun of the environmental effects of tallow forest and assessment of possible monoculture effects aimed at predicting impact upon the human environment and predicting potential pest and disease problems associated with large-scale cultivation of the tree. Average temperature was slightly higher in a prairie near the tallow forest, but probably was not different enough to adversely effect prairie organisms.

Genome resequencing reveals multiscale geographic structure and extensive linkage disequilibrium in the forest tree Populus trichocarpa  

Science Conference Proceedings (OSTI)

Population genomics of forest trees provides crucial information for breeding, conservation, and bioenergy feedstock development. As part of a large-scale association study, we resequenced 16 genomes of the model tree Populus trichocarpa to an average depth of 39 . Analyses of the resulting data revealed surprisingly extensive population genetic structure and decay of linkage disequilibrium over much larger physical distances than the expected based on previous, smaller-scale studies. Rates of recombination varied widely across the genome but were largely predictable based on DNA sequence and methylation patterns. Our results suggest that genomewide association studies and accurate prediction of phenotypes from DNA data are more feasible in Populus than previously assumed, thereby laying the foundation for a step change in our understanding of tree biology.
