The frantic computer code is the most advanced model for addressing time-dependent risk effects associated with technical specifications. it is used by the industry for the evaluation of upgrades and/or improvements in existing technical specifications and by the nrc staff in responding to the… More

The accurate detection of disease clusters is a well-acknowledged problem. false detections may be expectedunder repetitive testing, but the opposite situation, that of failing to detect clusters when they actually exist,is increasingly recognized. both false detections and failures to detect have… More

One of the most important methods to prevent and control tick-borne parasitic infections such as lyme disease is to understand the mechanisms by which foci of the disease develop. once that is done, we can attempt to manage the problem. lyme disease is the most prevalent tick-borne disease among… More

A common dilemma in ecosystem modeling is the complexity of biological systems and the lack of sufficient data. traditional modeling approaches require quantitative data and detailed knowledge of the ecological system. although such data may be available for small controlled systems suchas the… More

This project proposes to develop an objective methodology for forecasting insect pest population abundances and to implement this methodology as an interactive computer software package. for agricultural and forest insect pests we can generally obtain estimates of their population abundance over… More

Quantitative models of carcinogenesis that are based on stochastic proliferation of cell types have been suggested by several researchers. for the most part, these models exist only as equations in articles, or as specialized and non-portable software implementations. the consequence of this is that… More

Health professionals must often analyze disease cluster allegations made by concerned citizens who sense patterns within small structured environments. Examples include households, families, sibships, wards, cellblocks, classrooms, job types, age classes, and locations within a building. It is… More

Not Available This Small Business Innovation Research Phase II project will develop a software tool for evaluating the impact of forest management practices on the viability of endangered and threatened species. The objective of such a tool is to provide a generic, flexible and user-friendly… More

Not Available This proposal describes an innovative, ultrashort pulse laser system offering environmental stability, compactness and extremely high efficiency. This will be achieved by the use of a novel diode-pumped, mode-locked ytterbium fiber laser and fiber pulse stretcher, followed by a… More

Not Available In-flight calibration of optical instrumentation on spaceborne platforms is essential to provide accurate Earth Resources/Energy Budget trends. This critical need exists for a variety of applications including imaging radiometers. There is a need to devel

DESCRIPTION (Verbatim from the Applicant's Abstract): The risk from an environmental contaminant is estimated with a risk equation involving the contaminant's concentration and other factors. Because the overall goal of risk management is to ensure such risks are not… More

This Small Business Innovation Research (SBIR) Phase I project aims to develop methods and software that can be used to evaluate or explore the impact of human population and land-use changes on species viability. Changes in human population and land use affect the viability of native species… More

DESCRIPTION (provided by applicant): The risk from an environmental contaminant is estimated with a risk equation involving the contaminant's concentration and other factors. Because the overall goal of risk management is to ensure such risks are not intolerably large, we need some way to back… More

The proposed work extends Probability Bounds Analysis to model epistemic and aleatory uncertainty during early design of engineered systems in an Integrated Concurrent Engineering environment. This method uses efficient analytic and semi-analytic calculations, is more rigorous than probabilistic… More

Distribution and abundance of endangered species are adversely affected by changes in the land-use patterns that cause habitat loss, habitat fragmentation, pollution or other disturbances. As sensitivity to human impact on local, regional, and global ecologies increases, researchers, planners, and… More

To apportion resources wisely, decision makers need to estimate the location and importance of threats and vulnerabilities at local, regional, and national landscape levels. Dynamic, high quality, geographically explicit data are becoming more and more available for use as inputs to such… More

Forest insect pests cause significant economic and ecological damage every year. Dramatically increased pest activity in recent years suggests that changing climate conditions will inflate the uncertainty associated with pest risk assessments. Advances in forest pest risk analysis methodology are… More

DESCRIPTION (provided by applicant): In delimited populations, such as nursing homes, day care centers, prisons, hospitals, and cruise ships, serious outbreaks of illness generally produce limited absolute numbers of disease incidence. Moreover, these grou ps are often more susceptible to disease… More

DESCRIPTION (provided by applicant): Patient data collected during health care delivery and public health surveys possess a great deal of information that could be used in biomedical and epidemiological research. Access to these data, however, is usually limited because of the private nature of most… More
