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 proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior region is modeled with method of moments (MOM) and or hybrids of MOM with the uniform theory of diffr ...

Advanced Photonics Technology (APT) proposes to develop novel, wide-band, highly linear integrated-optical modulators based on low-loss waveguides in ferroelectric (e.g., lithium niobate and lithium tantalate) crystals with domain-inverted sections. The application of domain inversion to electro-optical modulators introduces a novel approach that allows the development of devices with low levels o ...

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 ...

It is the goal of Applied Optronics to develop, fabricate and package antimony alloy diode lasers capable of high power operation at wavelengths between 2 and 5 microns, and to design a practical, high performance master oscillator power amplifier (MOPA) device based on antimony alloy diode lasers. In the proposed effort, Applied Optronics will use newly developed aluminum, gallium, and antimony m ...

Investigation of failed composite components requires tress analysis to assess their structural integrity. Currently there exist no general-purpose software packages for composite structural analysis that are accessible to failure investigators who are not experts in these types of analysis. The proposed research and development effort will fill this void with a flexible user friendly, PC-based ...
