AcuSoft proposes to develop a set of HLA Development Tools to assist simulation software developers in their efforts to implement the HLA. The HLA Development Tools will support the Federation Execution and Development Process (FEDEP) and present an approach to solving the problems associated with the HLA's flexible FOM data definitions. A set of data visualization tools, such as a 2D Plan View ...

AcuSoft proposes to research and develop a Synthetic Environment RTI (SE-RTI). The SEDRIS initiative has established a new programming paradigm that provides lossless transmission of synthetic environment objects. The HLA has been designed to support interoperability and reuse of DoD simulations, and SEDRIS is a major component of HLA. Currently, the SEDRIS data model, APIs and format are prima ...

Because of the scarce network bandwidth available on the wireless links, data compression plays a critical role in the wireless system design. We propose to evaluate existing public-domain and commercial lossless data compression packages in the context of wireless networking. The specific criteria used include compression efficiency, compression speed, memory usage, and ease of being incorporat ...

This Small Business Innovative Research Phase I project seeks to combine the enhanced piezoelectric properties of single crystal perovskite ferroelectrics, recently discovered at Pennsylvania State University, with the electrostrictive properties of polyurethane to make a new class of "smart" materials for acoustic transducers. A tape casting process is used to form composite sheets compromising ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

The Department of Vocational Rehabilitation has determined that efforts to adequately serve Deaf clients could be greatly enhanced by a voice-to-sign translation system (Shalls, 1997; Ward, 1997). It is hard for DVR to hire enough VR Counselors fluent in sign language (Shalls) and very expensive to hire interpreters to handle all communication between Counselors and Deaf clients. Very few prospect ...

An improved computer module for representing rotor flow field effects on flight dynamics response is proposed for development. This model extends finite-state dynamic inflow models to address current limitations in predicting rotorcraft off-axis response to control inputs. The software module also includes features for representing rotor operation in the vortex ring state. The model is novel ...

Over 500,000 hearing disabled Americans are currently excluded from communicating in their most expressive idiom over long distance communications systems. Although widespread availability of electronic mail (e-mail) and electronic facsimile (fax) provide the means for these individuals to communicate in written English, both speed of communication and the level of personal interaction are signif ...
