Conventional rockets all use a traditional bell nozzle. The nozzle represents lost weight from a payload point of view, but is necessary to direct thrust and ensure that the exhaust gas expands at the correct rate. However, this expansion velocity is dependent on the external air pressure, and for a rocket, that pressure is constantly changing. In other words, traditional bell nozzles are a compro ...

Despite the advancement of prosthetics design, there exists a lack of quantifiable diagnostic fitment information for assessing the characteristics of the socket-limb interface. The lack of diagnostic data yield improperly fitted, uncomfortable, and unstable sockets. Responding to the need to develop innovative diagnostic tools for socket-limb interface quantification, TRI/Austin proposes an elec ...

Lynntech is developing an electrochemical pump (ECP) to enable high efficiency individual water purification systems for military and civilian applications.ECPs utilize >80% less power compared to traditional pumps and are compact, lightweight, low cost, and virtually silent which make them ideal for integration into small water purification systems.Coupled to commercially available filtration mod ...

Chronically implanted neural electrodes are becoming increasingly relevant a number of medical conditions ranging from the treatment of neurological disorders like epilepsy, Alzheimers, and Parkinsons disease as well as being used for brain machine inte

U.S. DOT’s Zero Emissions Transportation Initiative is looking to push the transportation sector greenhouse gas production to zero by 2050. This solicitation/topic addresses alternative energy sources for the light vehicle, motorcycle, and bicycle sector. With the continuing significant development in commercialization and availability of biofuels, the possibility exists to meet this goal, with ...

Knowledge Based Systems, Inc. (KBSI) is pleased to propose the design and development of “MySidewalk,” a mobile application that will facilitate the crowd-sourced collection of sidewalk inventory and condition assessment data. The proposed tool will utilize the recent advances in social networks, mobile data collection, and data mining to provide integrated sidewalk datasets. The proposed tool ...

We present the National Incident Visualization System, NIVS. NIVS is a combination of software elements that leverage the capabilities and prevalence of smart-phone technology to create a single point of reference for aggregated information and information sharing during a fire-based emergency at an airport. NIVS aggregates GPS location and status information from personnel and resources with Airp ...

With this research, we would like to provide new materials joining methods to the DOT. This will be achieved with a pulse energy store that has already demonstrated game changing capability in welding a wide variety of metals and alloys. The process we are proposing is known as Homopolar Welding. The weld is created by a solid state fusion welding process whereby high current is passed through ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

ARTIFICIAL INTELLIGENCE/EXPERT SYSTEM TECHNIQUES HAVE DEMONSTRATED THE ABILITY TO ADDRESS COMPLEX REASONING TASKS REQUIRED FOR PROCESS PLANNING. FEATURE-BASED DESIGN THEORY AND PRELIMINARY EFFORTS HAVE SHOWN THE POTENTIAL OF PROVIDING A FUNDAMENTAL MODEL FOR CAPTURE AND MANIPULATION OF DESIGN KNOWLEDGE. HOWEVER, THE TWO TECHNOLOGIES HAVE NOT BEEN SUFFICIENTLY INTEGRATED TO ALLOW DESIGN FEATURES TO ...
