The company is commercializing a mobile social computing system named Tiramisu (“pick me up” in Italian) that is intended to connect riders and transit service providers. It supports a variety of collaboration mechanisms designed to improve the experience of riders in a transit service and improve the service provided by service operators. The system has been designed using current knowledge i ...

Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation policy making, work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations (Van Dongen et al. 2003; Mollicone et al. 2010). Our group was the first to document the considerable magn ...

Plume signature phenomenology plays an increasingly important role in the development of a wide variety of missile defense technologies, both at the tactical and strategic levels. With the emergence of recent threats, plume signature phenomenology is increasingly central to Missile Defense Agency"s fundamental mission of development of a Ballistic Missile Defense System (BMDS). The Missile Defense ...

Missile exhaust plume radiant emission is a key observable for any missile defense system using optical sensors. Scene generation has become an important component within MDA to assess the performance of the BMDS system, and accurate rendering of the target during boost is essential for proper testing of system elements. The objective of this effort is to extend the use of image morphing techniq ...

Diode pumped alkali lasers have the potential to provide the required high efficiency for a laser-based missile defense system. However, traditional anti-reflective coating materials are not resistant to the alkali vapor environments associated with such systems, contaminating and degrading rapidly with use. Thus the solution to this challenge will almost certainly require the identification of ...

Because Critical Program Information (CPI) is often embedded in integrated circuits, adversaries must now attack at the die level. As a result, Focused Ion Beams (FIBs) have become a preferred tool for reverse engineering. FIBs can bypass or create circuit elements at the lowest levels; however, they induce inherent, characteristic side effects when modifying a semiconductor die. The proposed coun ...

LithChem Energy (LCE) has developed a very high power (>12,000 W/kg) reserve battery for use in interceptor missiles such as the SM3-IIB where weight (power density) is very critical. This battery can be 100% checked and cycled before actual mission use to ensure 100% reliability and can be turned on before launch. The LCE reserve battery (cell voltage 3.6 V) performs in the normal ambient tempe ...

Vernier engines operating at the same time as the main missile engine can change the overall structure of the engine exhaust plume. This SBIR focuses on the modeling of this interaction using techniques that do not require the use of high fidelity 3-D CFD computations. The proposed approach will develop a simple, overlaid 3-D mixing code, using locally linearized differential equations techniques ...

The proposed Phase I effort involves the formulation of improved models to accurately simulate the particles that are present in rocket exhaust plume flowfields with the goal of obtaining improved plume signature predictions. While the modeling of the exhaust plume flowfield is a relatively mature technology, the sub models that are utilized to describe the behavior of the particle phase are in n ...
