"The objective of this project is to develop and validate a 2nd generation crack-growth prediction methodology for cold-worked fastener holes. The methodology will be based on a three-dimensional weight function, and will handle cracks growing from theedge of the hole, as well as cracks initiating in the residual tension zone away from the hole. A predictive capability, based on probabilistic fa ...

"We propose to develop a heat flux sensor that can be used to estimate the temperature and heat flux on the far side of a wall as a function of time. The configuration of the sensor is specifically designed to minimize the sensor's impact on thetemperature and heat flux boundary conditions on the sensor's side of the wall, while allowing for both the capability of measuring very high heat fluxes ...

"A significant problem for stakeholders in large satellite systems is the difficulty of getting data about these systems when it counts the most - in orbit and during critical anomalous situations. Near-field diagnostic tools - including visual andinfrared images and close-range radio frequency measurements - are now becoming feasible to examine performance, anomalies, and failures on orbit.AeroA ...

"In this work, we propose to capitalize on our experience with synthetic jet actuation, low order system modeling, and control in order to develop an integrated approach to hingeless flow control. We first propose to develop a new, hybrid, synthetic jetactuator that will be capable, via real-time actuator parameter control, of both separation manipulation (reduction, elimination or promotion) and ...

"We propose an innovative technique for ultra rapid, sensitive detection ofcancer specific chromosome rearrangements in solution to facilitate bulkquantification of aberrant chromosomes for early detection of metastatictumor cells. (I) We will apply DNA hybridization in suspension to humanbreast cancer cell lines by combining two separate, novel techniques 1)hybridizing chromosomes in suspension; ...

"The goal of this Phase 1 proposal is to examine the technical feasibility of a cognitive performance self-assessment wearable computer system for operational deployment. We will use the standardized and validated software for assessment of cognitiveperformance, ANAM - Automated Neuropsychological Assessment Metrics, which is a set of computer administered and scored tests of cognitive processing ...

"Fretting is a wear phenomenon that occurs between two mating surfaces: it is adhesive in nature, and vibration is its essential causative factor. Usually fretting is accompanied by corrosion. In general, fretting occurs between two tight fitting surfacesthat are subjected to a cyclic, relative motion of extremely small amplitude. Fretted regions are highly sensitive to fatigue cracking. Under fre ...

"The Air Force is pursuing aircraft and satellite-based high power laser systems to engage and destroy missiles at long ranges (hundreds to thousands of kilometers). A precision inertial reference unit (IRU) is critical to successful operation of longrange, high power laser systems for missile defense. The IRU enables the system to accurately point the payload telescope and attached tracking sen ...

"One of the critical capabilities to enhance the availability and performance of C4I systems for Homeland Defense and other major Air Force initiatives (e.g., DMFE, TAS, DICE, Broadsword, JBI, SSW and BP) is indexing and retrieval of large multimedia,multi-source information. Current indexing and retrieval techniques in these systems are based on limited sets of keywords and simple lookup tables. ...

"The team of Artis, LLC, Noesis, Inc. and Brandeis University will address four objectives in Phase I. First, we will develop a system, the Virtual Motion Induction System (VMIS), that couples the sensed motion in the environment to a simulatedenvironment. The purpose of VMIS is to reduce the onset and severity of motion side effects. Second, we will test VMIS on multiple laboratory motion plat ...
