Project Summary/Abstract NIEHS defines environmental health as “the field of science that studies how the environment influences human health and disease”. The environment in this definition includes the natural environment, man-made chemicals and structures that often pollute the natural environment, and our social interactions and lifestyle choices. Because toxic environments are linked dire ...

The key innovation proposed in this STTR effort by Intelligent Automation, Inc. and Duke University is a hybrid level set based algorithm to achieve dynamic perimeter surveillance within a region by constructing an evolving function based on the perceiveddensity of a phenomenon. Drawing on state-of-the-art image processing methodologies, the hybrid solution offers the flexibilities of an Eulerian ...

In the phase I effort, IAI successfully demonstrated the feasibility of co-operative swarm based approach to boundary tracking. This approach is relevant to applications such as tracking oil spills using a swarm of robots, tracking enemy troop movement using a swarm of UAV's (Future Combat System (FCS) type scenario), and tracking of static and moving mine fields . In Phase II, we continue our ef ...

This research will investigate a new technique for analyzing operation characteristics of future space transportation systems using a variation of activity based cost modeling. The unique element of the new technique is its focus on simulation modeling to translate vehicle design parameters into a set of activities and a related process map in a domain (operations characteristics of future space v ...

Physicians are highly burned out (up to 80% of physicians) and the COVID-19 pandemic is making this problem much worse; Department of Defense doctors are at higher risk (caring for more patients per capita).  Burnout may manifest itself as sustained stress; but also leads to severe effects such as physician suicides, physician drug abuse, and increased patient medical errors.  Electronic health ...

Metron has developed a detector-tracker for Mid Frequency Active (MFA). This detector-tracker computes likelihood functions and likelihood ratio surfaces from the un-normalized matched filter output of the MFA system. While doing this we have discovered a number of features that significantly reduce false alarms. The process involves identifying a feature, characterizing its statistical behavior, ...

Commercial tools have been developed that support the graphical construction of behavioral models of reactive systems and implement various forms of analysis of such user-developed models. These methods rely primarily on simulation, that is, the execution of a model on sample data. We propose to take advantage of the extensive effort that has gone into making the graphical user interfaces of the ...

DESCRIPTION (provided by applicant Adolescent and young adult (AYA) hematopoietic stem cell transplantation (HSCT) patients face a variety of well-documented physical and emotional challenges. In addition to undergoing a life-threatening procedure that involves an intense treatment regimen and lengthy hospital stay, these patients face a protracted 12-month recovery period marked by numerous physi ...
