The primary objective of this proposal is to develop an understanding from first principles of the macroscopic particle force equation arising from the microscopic particle and field interaction dynamics and to incorporate those effects in a self-consistent state-space (rate equation) PIC calculation. Effective current and charge density time-domain equation models will ...

An important problem in the analysis of ATR systems is quantifying the growth of algorithm requirements, such as storage and processing cost, as the input problem l situation in classical complexity analysis, where the notion of input size is well-defined, there does not currenlty exist a clear notion of input size for the ATR problem. In this effort ...

Altair Center proposes to develop a novel and innovative compound-core multimode active flber for high-efficiency fiber laser systems capable to operate in a single-mode regime. The compound multimode core of the fiber is especially designed in such a way to support propagation of a higher order mode exhibiting a sharp peak of its field in the central region of the core. The sharp-peak mode extrac ...

The proposed program will develop a liquid crystalline Adhesive with Zero Shrinkage, for bonding of airframe joints. Aspen Systems, Inc. is currently in the process of developing a new class of epoxide resins. These new epoxy materials are based on orderable, low molecular weight liquid crystalline structures with flexible, difunctional end chains. The structural ordering of the liquid crystallin ...

More compact high voltage firing capacitors are required for state of the art detonators used for advanced electronic fuzes. This can be achieved via development of a superior dielectric based upon combination of a processible polymer and a nanoparticulate ceramic material having a very high dielectric constant. While accomplishing this task, the composite must offer a breakdown strength of at l ...

Non-destructive inspection and evaluation (NDI, NDE) of adhesive joint integrity commonly requires separation of an interface or, in limited cases, a kissing unbond that has intimate contact, but no interfacial strength. DACCO SCI, Inc., and Michigan State University propose to adapt an in-situ corrosion sensor to detect the ingress of moisture into a bondline and the subsequent deterioration of ...

This SBIR Phase I proposal is aimed at development of propulsion systems for EKV and divert. propulsion systems for low-mass interceptors that will use Vector Thrust Pulsed Detonation Rocket Engine (VTPDRE) technology. Use of PDRE will increase power density, enhance modularity, and reduce cost. Further improvements will be realized by introducing configurations with multiple PDREs and non-mechani ...

Proposed are the development of novel differential geometric tools for the visualization of multi-spectral imagery. These tools will enable a user to optimally visualize local image contrast inher-ent to a multispectral image in a psychophysically correct way. These tools will also enable a user to dynamically interact with a Riemann metric on photometric space for optimal contrast visual-ization.

The autonomous control of a hypersonic missile from launch to target is a very challenging problem. F&S proposed to use a combination of experiments using MEMS and numeric simulations using CFD, to train a neural net for the control of micro-jets. The trained neural net control system would be able to control a hypersonic missile throughout its flight. Such a system could possibly be used to re ...

Revolutionary ionically self-assembled monolayer (ISAM) methods of creating multifunctional thin-films monolayer by monolayer have recently been proven to yield self-assembled, electronically and phonically--active polymeric thin fi!ms. F&S and Virginia Tech have demonstrated that the ISAM technique can be used to fabricate both polymer light emitting diodes and inherently noncentrosymmetric elect ...
