This project seeks to reproduce the neural circuits used by the nematode Caenorhabditis elegans for locomotion. Caenorhabditis elegans is a small (~1.2 millimeter) nematode found in rotting...

On military live fire training ranges, troops practice firing artillery shells, drop bombs on old tanks or derelict buildings and test the capacity of new weapons. But those...

The threat of improvised explosive devices (IEDs) to human life is grave, and countering this threat is a high priority for force protection during military...

Molecules have internal motions that are characteristic of their structure and identity. These motions can be studied by spectroscopy in different regions of the...

US national and many international hearing conservation programs (HCPs) have adopted a noise exposure criterion of 85 dBA for a time-weighted average of 8 hours, with a 3...

Using the current method of characterizing waveguides manufactured for research in optical communications, it can take up to 8 hours to characterize the...

The SuperMISTI detection system is a hybrid detection, identification, and imaging system for sources of gamma-ray radiation at stand-off distances. The system is based on...

Cascading Failures in Coupled Distributed Power Grids and Communication Networks

Emerging distributed power grid systems will integrate tightly coupled networks, namely a power grid and a communication network, to provide distributed power monitoring and control. While distributing power monitoring and control away from a central site enhances...

The objective of this work was to develop a high-speed, three-dimensional (3D) confocal imaging system to study coupled fluidic...

Given the current emphasis on sustainability, there is a growing interest in monitoring various facets of building resource consumption. Building monitoring and automation...

Abullet cannot penetrate through a sandbag while an arrow can, so understanding the behavior of granular materials such as sand and its energy absorption in a blast is...

T he human sensory systems most frequently used in military displays (vision and audition) are sometimes overloaded. When soldiers rely on visual or auditory displays, their situation...

Given remote and direct physical measurements of a realistic ocean wavefield, the goal of this work was to obtain a high-resolution description of the...

Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated...

Polymer composites comprised of metallic particles distributed throughout a contiguous polymer matrix can often be modified to produce advanced composites...

The testing of individual respiratory protection (IRP) devices is now accomplished with panels of human wearers. Historical at tempts to simulate the human face and head have...

Wheel Force Transducer for Field Testing

This project endeavors to develop, validate, and calibrate cost-effective field test equipment for measuring tire characteristics on vehicles while driving off-road. The four wheel force transducers...

Turbines in aircraft turbojet engines are being subject to increasingly higher temperatures to improve fuel efficiency. High turbine efficiency requires the ability of turbine blades to...

The US Marine Corps and the US Army have been engaged in efforts to evaluate improved body armor, including armor to protect the extremities. These efforts are focused on both body armor...

An oscillating current flowing through a coil produces an oscillating magnetic field. When an electrically conducting material like a metal is brought...

The onset of local damage in structures, such as delamination, cracking, and fastener loosening, can often be difficult to detect and has long-term implications on the...

Guided waves (e.g., Lamb waves) have been considered for many structural health monitoring (SHM) applications because of their ability to travel long distances and maintain...

To address the need to protect our borders and critical infrastructure, fiber optic sensing technology developed for antisubmarine warfare applications has been adapted to homeland...
