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 ...

The major hindrance in the way of integration of a laser source and an external modulator in ferroelectrics has for long been the lack of efficient waveguide lasers and amplifers suitable for integration in these materials. However, with the recent resurgence of interest in rare-earth doped, waveguide lasers in LiNbO3 and in view of the promising results already achieved, the on-chip integration ...

Cryogenic cooling objectives for space applications require reduced size, weight, and input power; longer life and increased reliability; and increased net cooling load. The Reverse-Brayton expander cycle has the potential to meet all these objectives. Previous efforts to implement this cycle for long-life cryocoolers utilized "room temperature" tilting pad bearings. The warm bearings provided ...

Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their interaction with the target geometry, to the development of loads on and response of the target structure. ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...

Secure broadcasting mechanisms play an important role in satellite-based communications networks. In this Phase I SBIR project, Artery Communication Technology Inc. proposes a scalable secure data broadcasting architecture that is both bandwidth efficient and as secure as state of the art public key cryptosystems. The major emphasis of this project is to analyze the detailed performance behavior ...

The U.S. Air Force has identified a need to develop innovative inertial sensor configurations and algorithms that utilize multiple low-cost, low-performance sensors to produce an inexpensive inertial measurement unit (IMU) with relatively high performance. A multiple-sensor IMU uses several low-performance sensors per axis and blends their outputs to attain an accuracy comparable to a higher-perf ...

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 ever increasing complexity of distributed simulation environments has caused the level of effort required to manage and control a training exercise to become excessive. Exercise setup times and the number of human operators/instructors, needed to run an exercise, have reduced the number of useful training hours and increased the cost to train. To combat this situation, a more efficient means ...
