Taggants are small objects used to label things or people that need to be traced. Synthetic DNA Taggants are ideal for this, since very small amounts can be detected if the sequence is known, and can be disguised by natural DNA in the environment. Known protocols for DNA amplification (e.g. PCR) allow for very sensitive DNA detection, but suffer from disadvantages: the apparatus is not very portab ...

The objective of this SBIR project is to develop an attached processor called an "agent based computing" module (ABC Machine) that is optimized to convert information into knowledge and enable "cognitive computing" for higher understanding. The architecture of the ABC Machine is based upon a concept called "statistical dataflow computing" and it operates in local contexts over string operators. I ...

THE ANALYSIS OF AEROBALLISTIC RANGE DATA IS A TEDIOUS AND TECHNICALLY CHALLENGING TASK. THE SOPHISTICATED ANALYSIS PROCEDURES AND REQUIRED SOFTWARE (COMPUTER PROGRAMS) HAVE BEEN REFINED EXTENSIVELY DURING THE PAST FIFTEEN TO TWENTY YEARS WITH THE ADDITION OF THE SIX-DEGREE-OF-FREEDOM CODES EMPLOYING THE MAXIMUM LIKELIHOOD METHOD. THE REQUIRED PROFICIENCY TAKES BETWEEN THREE AND FIVE YEARS UNDER TH ...

79454S Despite advances in modern electron optics, which have permitted observation with unprecedented resolutions, most materials science research involves the quantification of static properties of materials. This is mostly due to limitations in modern day equipment and the time and cost associated with modifying existing microscopes. Consequently a need exists to extend the current ability t ...

The conventional thermionic cathodes used in traveling wave tubes (TWTs) suffer from many technical limitations including limited current density, poor energy efficiency, difficulty of control, and lack of miniaturization. Xintek, Inc. has developed proprietary technologies for fabrication of high performance field emission cold cathodes based on carbon nanotubes (CNTs). Our CNT cathodes tested at ...

A novel method of creating hot electrons via a pn junction will be used to eject electrons from a cold cathode. The accelerated electrons will have suficient energy to surmont the work function and surface dipole. The cold cathode will be used in a new type of minature Traveling Wave Tube or "Twystrode". Advanced semiconductor materials with low work functions will be produced and evaluated as pla ...

Saffron Technology, Inc., www.saffrontech.com, is the leader in the application of associative memory technology in cognitive computing applications. This work will identify and solve the computational architecture issues associated with creation of a hardware associative computing element and its integration into emerging cognitive computing architectures. This phase one effort will lead to a d ...

Software tools will be developed that define the underlying phenomenology of greatest importance to radar CID performance, allowing a trace back to the responsible target scattering physics. The proposed research entails development of algorithms that identify the target-sensor orientations (poses) of most relevance for classifying targets of interest to AFRL. These target-sensor poses will then b ...

THE PURPOSE OF THE PROPOSED PHASE I PROJECT IS TO DEMONSTRATE THAT A USEFUL SOFTWARE INTERFACE CAN BE CONSTRUCTED THAT IS CAPABLE OF FAITHFULLY CONVERTING NORMAL COMPUTER-AIDED DESIGN (CAD) OUTPUT FILES INTO A FORMAT THAT IS DIRECTLY READABLE BY THE GEANT HIGH ENERGY PHYSICS DETECTOR SIMULATION CODE. GEANT, ORIGINALLY DEVELOPED IN THE 1970S, HAS EMERGED AS A STANDARD TOOL FOR DETECTOR SIMULATION; ...
