Detecting explosives and weapons under clothing or in hand carried packages, and imaging terrain and objects through fog and smoke are two high-priority needs that can be met using light in the Terahertz frequency range. However, to image concealed threats, and aid in navigation in fog and smoke, a practical, low cost THz camera is needed. Intelligent Optical Systems (IOS) in collaboration with Re ...

Quantum cryptography, and in particular Quantum Key Distribution (QKD) is a secure method to distribute a secret key between two distant authorized partners whose security is based on the laws of physics. Current public key cryptosystems have not been proven to be secure and are based on the computational complexity of evaluating one-way functions. These functions are easily evaluated, but extrem ...

The objective of this project is to develop a practical finite element-based simulation of spin-pit tests of disks. The performance of disks in spin-pit tests critically depends on localized effects, such as residual stresses, dislocations, and microstructure gradients. Therefore, a two-scale modeling approach is adopted. At the global-scale, the disk is represented by means of finite elements wit ...

The need for faster highly resolved solutions coupled with the advent of General Purpose Graphics Processing Unit (GPGPU) architectures and the development of GPGPU algorithms at the University of California, Davis present an opportunity that JMSI Inc. proposes to leverage by developing algorithmic and software solutions for GPGPUs in “Innovative CFD Algorithms, Libraries & Python Frameworks for ...

Accurate and timely surveillance of objects in the near-Earth space environment is becoming increasingly critical to US national security. One of the main difficulties in this domain is efficiently and accurately modeling trajectories of the vast number of objects in orbit around the Earth. The orbital trajectory of a single object is typically modeled as a second-order system of equations which ...

Space surveillance is the component of space situational awareness focused on the detection of resident space objects (RSOs) and the use of multisource data to track and identify space objects. While the propagation of the states of RSOs has been investigated extensively over the last fifty years, the correct propagation of their covariance or the more general (non-Gaussian) probability distribut ...

A mathematical framework for detection and classification of weak, distributed patterns on computer networks is proposed. The framework will provide rigorous methods for understanding performance bounds and optimality of intrusion detection methods, while also providing concrete and implementable algorithms. The algorithms will find immediate application in cyber-security efforts, as well as mor ...

ABSTRACT: The proposed research will demonstrate feasibility of a high temperature insulating, load bearing thermal protection system (TPS) using a hybrid composite technology. This program will incorporate a hierarchically porous ceramic core material in a sandwich structure with a conventional polymer matrix composite (PMC) and ceramic matrix composite (CMC) to fabricate an enhanced TPS. This m ...

We intend to use the emerging technology of compressed sensing and related new algorithms of information science to (1)increase our capacity for hyperspectral image acquisition beyond current capacity by developing new imaging and spectroscopic systems,(2) expand the frontiers from signal recovery to new applications, emphasizing knowledge learning including target and anamoly detection, and (3)st ...
