A major problem of existing pulse expanders is that each of them was designed for a certain expanding ratio at a certain wavelength. When the laser wavelength or pulse duration is changed the optical components of the systems require precise readjustment, which are extremely inconvenient and time consuming. Luna proposes a novel approach, which is designed specifically for easy alignment and ins ...

There is growing interest in using unmanned air vehicles (UAV's) instrumented with particle sensors to detect the presence of hazardous airborne chemical/biological (CB) agents. The effectiveness of this point source approach depends on providing the airborne sensors with the largest possible and most varied volume of the atmosphere. We seek to investigate whether or not the local flow upstream of ...

The goal of this project is use Answer Set Programming (ASP) methods to create a commercially viable software application (“SocioLogix™”) for social network analysis (SNA). Recent developments in Answer Set Programming and propositional satisfiability checking (SAT-checking) have potential to extend the power of software to use techniques of rule-based or “qualitative” optimization to f ...

AUTOMATIC IDENTIFICATION OF TARGET INFORMATION USING RADAR CROSS SECTIONS IS AN EXTREMELY DIFFICULT PROBLEM. A LARGE AMOUNT OF EFFORT HAS BEEN DEVOTED TO THE PROBLEM OF ESTIMATING THE RADAR CROSS SECTION OF VARIOUS SHAPES, BUT THE RANGE OF POSSIBLE OBJECTS WHICH CAN BE ENCOUNTERED IS LARGE, AND MEASURES CAN BE TAKEN TO ALTER THE APPEARANCE OF A RADAR CROSS-SECTION. IN ADDITION, AN OBJECT CAN BE VI ...

This Small Business Innovation Research Phase I project focuses on the development of a novel process for applying metallurgically-bonded coatings to thin or otherwise thermally sensitive components. The technique, suitable for both OEM and field-repair applications, is a low-thermal-impact technique for deposition of fully fused coatings for applications such as component wear and corrosion prote ...

THIS STUDY UNDERTAKES AN ASSESSMENT OF THE MILITARY MARKET FOR APPLICATIONS OF AN OXYGEN EXTRACTION TECHNOLOGY BEING DEVELOPED BY DARPA AT THE AQUANAUTICS CORPORATION. THE POTENTIAL APPLICATIONS IDENTIFIED THROUGH A LITERATURE SEARCH AND TECHNICAL DISCUSSIONS WITH DEVELOPING AGENCIES ARE SUBJECTED TO AN OPERATIONAL, TECHNICAL, AND ECONOMIC FEASIBILITY ANALYSIS TO DETERMINE WHICH APPLICATIONS HAVE ...

We propose a systematic solution to the problem of efficient summarization, visualization, and browsing of large combat video archives. Our approach is event-driven: spatio-temporal saliency is used to define significant visual events, which is in turn used in an event-based video model to partition the video into interleaved salient and less significant segments. Each of the two types of segments ...

Arbitrary waveforms are important for advanced coherent communication systems envisioned for several potential military uses. Such systems require waveforms from high frequency bandwidth sources, where the amplitude and phase of each of the frequency components are independently controllable. Example systems include advanced radar, advanced LIDAR, frequency agile optical fiber communication, and q ...

A NOVEL CONCEPT IS PROPOSED TO DEVELOP COATINGS WITH DUAL RADAR AND THERMAL SUPPRESSION CHARACTERISTICS. THE CONCEPT EMPLOYS WELL KNOWN TECHNIQUES USED FOR RADAR ABSORBING COATINGS AND COMBINES THEM WITH TECHNIQUES FOR PRODUCING LOW EMISSIVITY SURFACES IN THE INFRARRED WAVELENGTHS IN A WAY IN WHICH TOTAL COMPATIBILITY IS ASSURED. VARIOUS COMBINATIONS OF MATERIALS DEMONSTRATING THE APPROPRIATE PROP ...
