The objective of this project is to develop and validate a CAD tool for the rapid design of mechanically fastened repairs, bonded repairs, and hybrid repairs involving both adhesive bonding and mechanical fasteners. To allow use by non-specialists, the CAD tool will replace the current process of manual construction of joint finite element models with CAD tinker toy assembly using parametric par ...

The goal of this proposal is to find novel combinations of approved drugs for the treatment and/or prevention of infection with filoviruses. Ebola and Marburg viruses, the only filoviruses, cause an acute hemorrhagic fever syndrome which has a high mortality rate and poses a significant bio-terrorism threat. There are currently no therapeutic agents available to treat filovirus infections and the ...

This proposal offers an approach to integrate the latest corrosion sensor technology with corrosion structural effects modeling to enable the transition from periodic corrosion inspections to an efficient, focused prognostics and health monitoring (PHM) system. The fundamental vision of the proposed program is to provide the customer with a process suitable for integrating corrosion effects analy ...

We propose to develop a computer based system for the online analysis of bio-behavioral signals associated with momentary loss of alertness. We will continue our development of bio-behavioral measures indicative of lapses in alertness. Our system will use only measures that can be obtained without attaching sensors to the operator. We will concentrate on monitoring the oculomotor system using came ...

Software development organizations are faced with developing and verifying required system software capability, functionality, performance, reliability, and safety, while at the same time meeting tight budget and schedule constraints. Due to software complexity, many programs experience mission critical failures and incur schedule delays and cost overruns. The Army and other organizations, there ...

A computational system is required that contains validated/certified tools and models that can be readily employed by non-FEM experts. Designers would be able to input parameters, such as panel bay spacing, boundary conditions, skin material and thickness, skin stiffness, flushness requirement, and scarf angles, while the system would automatically construct a valid finite element representation ...

Investigation of the feasibility of development of a mathematical model that will have the capability to provide machine operators with specific guidelines for efficient machining, while minimizing any distortion and warpage, is the main objective of the proposed Phase I effort. The most challenging aspect of this project is the development of a validated mathematical model for the effects of mach ...

Within our Phase I effort, a radically new kind of neural network based control system that broadly emulates the contemplative capacity of the human brain has been successfully tested aboard a complex hexapod robot. In the course of this preliminary investigation, this neurocontrol system was able to bootstrap its own locomotive behaviors on demand, integrate camera images and sonar returns to bui ...

A system that provides a large field of regard for propagation of a lethal beam from a transonic platform will be evaluated. The proposed design incorporates concepts to address the fact that shocks do develop in transonic flow, but with the proposed system the field of regard should be enhanced. A second feature is provided that allows a simple method of controlling optical aberrations imposed b ...

A recently developed nonlinear controller called theta-D and the Higher Order Sliding Mode (HOSM) control are the centerpiece around which an Integrated Guidance and Control (IGC) scheme and a nonlinear filter technique are built to enhance the lethality of hit-to-kill interceptors and offer a means to increase the maneuver ratio advantage. This proposal includes the development of a 6DOF based I ...
