Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations. This project will deliver an individualized Fatigue Management Program (FMP) technology for trucking operations that in ...

This proposal describes the application of a mature nanotechnology-based crack arrest / structural repair technology as a novel crack arrestor tool for high-strength pipelines. The crack arrestor would comprise a thin layer or sleeve of electrodeposited nanocrystalline material applied to the outside of the pipe either in the coating mill during fabrication or in-field during or following constru ...

Laser Technology Inc. (LTI) proposes a Phase II SBIR research project to further develop a Compact Shearography System, Analysis Method and Software for micro-crack detection in concrete. There is an urgent need to detect and characterize fine cracks in concrete that form because of various damage mechanisms including alkali-silicate reaction, delayed ettringite formation or frost damage. Fine s ...

Development of the basic EMAT based transverse rail defect detector has progressed toward finished form, as envisioned in the original solicitation. This modification is intended to produce a demonstratable version of a 2-rail detection system with automated signal interpertation. The objectives of this work are to: a. Further develop the system into a functioning 2-rail detection system, as ori ...

The Airborne Laser (ABL) program has significant cooling requirements that until present can only be addressed by mechanical refrigeration systems. These include cooling of the various high powered solid state lasers currently used on the ABL for tracking and ranging as well as standby cooling for the basic hydrogen peroxide (BHP) loops on the Chemical Oxygen Iodine Laser (COIL). The proposed inte ...

Cities must perform detailed assessments of sidewalks and streets, including curb ramps, pedestrian signals, crosswalks, street furniture, and other components to determine compliance with the Public Rights-of-Way Accessibility Guidelines. However, current assessment methods are inadequate or unreasonable due to time and resources required. The objectives of this project are to: 1) develop elect ...

Intense dynamic and thermal loads will occur during stage-separation events that are of major concern from both operational and safety viewpoints. The insensitive-munitions (IM) stimuli and thermal/dynamic response associated with such events has received very little attention, yet this is of major concern for the KEI vehicle undergoing Stage 1 to Stage 2 separation. The KEI event is at lower alti ...

Propulsion systems may perform a variety of maneuvers during the ascent phase of flight that can impact the performance of an interceptor or other parts of an MDA system designed to perform threat detection, discrimination, and tracking. Our Phase I effort focuses on building on extending existing plume signature software. A main technical objective is to establish the various components and app ...
