We present Brown Dog, two highly extensible services that aim to leverage any existing pieces of code, libraries, services, or standalone software (past or present) towards providing users with a simple to use and programmable means of automated aid in the curation and indexing of distributed collections of uncurated and/or unstructured data. Data collections such as these encompassing large varieties...
DIBBs Brown Dog is a recent cyberinfrastructure effort which aims to create two new services to aid users in the searching, accessing, and usage of digital data and provide these services in a manner that is as broadly and easily accessible as possible. At its lowest level, the Data Access Proxy (DAP) providing file format conversion capabilities and the Data Tilling Service (DTS) providing content...
Work is underway to demonstrate a new linear mode photon counting (LMPC) detector in Earth orbit inside a 3U Cubesat. The detector is 16 pixel (2×8) HgCdTe electron Avalanche Photodiode (e-APD) array developed by DRS Technologies, C4ISR Group, Infrared Sensors and Systems (ISS). It has ∼70% quantum efficiency and single photon level response at wavelengths from 0.4 to 4 microns. The detector will...
Several generations of high power, lateral, linear mode, intrinsically triggered 4H-SiC photoconductive semiconductor switch designs and their performance are presented. These switches were fabricated from high purity semi-insulating 4H-SiC samples measuring $12.7~{\rm mm}\,\,\times \,\,12.7~{\rm mm}\,\,\times \,\,0.36$ mm and were able to block dc electric fields up to 370 kV/cm with leakage currents...
Recent work on Coaxial Ferrimagnetic Nonlinear Transmissions Lines (NLTL) has been focused on developing an array of NLTLs for use as a solid-state High Power Microwave (HPM) source. The pulsed output of an NLTL requires a combiner that enables combining transient signals at voltage levels up to 50 kV. Existing combiner designs found in literature require resonant structures to achieve efficient power...
Forming non-rectifying (ohmic) contacts to wide band gap semiconductors such as silicon carbide (SiC) requires a heavily doped subsurface layer to reduce the Schottky barrier height and allow efficient electron injection. Nitrogen, a common n-type dopant in SiC, was incorporated into a SiC sample using a laser enhanced diffusion process in which an impurity is incorporated into the semiconductor to...
