ADHESIVES CURRENTLYUSED ON AIRPORT PAVEMTNS FOR LIGHTING /ELECTRICAL INSTALLATIONS HAVE DIFICIENCIES, AND INNOVATIVE USE OF OTHER ADHESIVE COMPOUNDS, OR MATERIALS, THAT WOULD PROVIDE IMPROVED PALCEMENT QUALITIES, AND INCREASED ADHESIONCHARATERISTICS WITH ASPHALTIC MATERIALS IS NEEDED. THIS PROPOSED PROGRAM WOULD AID IN DEFINING THE PROBLEM QUANTITATIVELY, ESTABLISH PERFORMANCE CRITERIA FOR THE ADH ...

It is proposed to develop a full prototype next-generation semi-flush flasher system for airport runway approach lighting. Current systems are many years old and inefficient; airports need inset flashers to add runway length and more efficiently use strictly limited land allocations. An inset flasher is proposed that is optimized both optically and electrically. A flasher fixture based on the P ...

TDA Research, Inc. (TDA), designed, built, and tested a dense array of 100 very low cost infrasonic sensors. Due to their low cost (1/100x-1/10x the cost of other infrasound sensors), they can be economically deployed in very large numbers; such large arrays can gather more information than a few expensive sensors. They are sensitive from 0.1 Hz - 100 Hz down to 0.08 Pa. We tested the sensors in s ...

This project involves building and demonstrating a wireless seismic system for assessing the condition of railroad ballast.The system is designed for portability and ease of use by non-specialized personnel. It is based on the well-known multi-channel analysis of surface waves (MASW) method. The system consists of a seismic source and an array of receivers. The source will be empirically optimized ...

THIS PROJECT WILL DEMONSTRATE THE VALUE OF DELIVERING INTERMODAL FREIGHT DATA TO A WIDE VARIETY OF TRANSPORTATION PLANNERS; FEDERAL, STATE, LOCAL AND ULTIMATELY SOME PRIVATE SECTOR USERS. THE PROJECT'S CHALLENGE IS TO MAKE DATA ACCESSIBLE IN TERMS OF THE USER'S ABILITY TO INTERACT WITH VARIOUS SOURCES AND DEPTHS OF INFORMATION AND THE SYSTEM'S ABILITY TO BE TIME RESPONSIVE. THE FACT THAT THE DATA ...

THIS PROPOSAL DESCRIBES AN INNOVATIVE FILTERING TECHNIQUE THAT CAN BE USED TO DETECT AND REJECT OUT-OF-TOLERANCE MEASUREMENTS FROM A DIFFERENTIAL GPS NAVIGATION SOLUTION. THE TECHNIQUE CAN BE APPLIED FOR BOTH MOBILE AND STATIC APPLICATIONS AND COULD BE INTEGRATED INTO SHIPBOARD OR REFERENCE STATION GPS RECEIVERS. USING THE FILTER DESIGN PROPOSED, ERRORS CAUSED BY MULTIPATH, SATELLITE, RECEIVER ORR ...

Environments created from a nuclear event can have a great impact upon the operation of military forces on the battlefield. It is imperative that the associated nuclear effects are portrayed in an environment such as Dirstributed Interactive Simulation (DIS) so that changes canbe made during the weapon system design process to mitigate nuculear effects. These effectscan be extended to other appl ...

In this proposed Phase II program we will build on the successful Phase I program where we for the first time implemented engineered epitaxial layers based on nanostructure technology that were used to harden commercial silicon devices against radiation by minimizing collected photocurrents (electron-hole pairs) via recombination centers where we demonstrated that improved radiation hardness could ...

A FEASIBILITY STUDY OF IMPROVING DECOY PENETRATION AID (PENAID) PERFORMANCE BY SUPPLYING MEANS TO 1) ALLOW FOR DUAL CENTER OF GRAVITY (CG) LOCATION, THEREBY ENABLING INDEPENDENT FULFILLMENT OF IMPULSE BALANCING AND REENTRY STABILITY REQUIREMENTS; AND/OR 2) COUNTERACT DECOY CONING BY SENSING ITS PRESENCE, AND CORRECTING THE ANGULAR MOMENTUM OF THE DECOY TO ELIMINATE CONING.

Welkin Sciences proposes to design and build a new fading channel simulator to be called the All-Digital Configu­rable Link Test Set (CoLTS–AD). It will be capable of emulating the full range of MIL-STD-3053 scintillating channel conditions needed to test all of DoD’s strategic communication systems. CoLTS–AD will support developmental and ac­ceptance testing of conventional communication ...
