Commercial silicon carbide (SiC)-based photonic sensors typically use p–i–n photodiode and reversed-biased Avalanche Photodiode (APD) detectors. These state-of-the-art SiC photodioides use the wafer substrate as one node of the device, thereby making monolithic integration of the device with control or analysis circuitry difficult, if not impossible. Ozark IC's new (patent pending) phot ...

The objective of this proposal is to develop and commercialize a high reliability, high temperature smart neutron flux sensor for NASA Nuclear Thermal Propulsion (NTP) systems. Arkansas Power Electronics International (APEI) and International Femtoscience (FemtoSci) technology offers the following: (1) 600+ degC ambient operation of a full wireless smart sensor system (2) Extreme-environment elec ...

Geothermal energy is a cost effective, reliable, environment-friendly, and sustainable energy source that has been utilized for space heating since Roman times but is now in recent years has become more attractive for its use in electricity generation. In order to harvest this energy, components must be subjected to extreme environments driven by high temperatures and pressures between the crust a ...

Poultry is a large component of livestock animals representing a multi-billion dollar industry. Chickens are raised under high density conditions and exposure to infections by opportunistic pathogens spreads rapidly and can have devastating economic impact. Cytokines such as Chicken Interferon-gamma (ChIFN-γ) have shown to have adjuvant and growth promoting activity in poultry and livestock. Thei ...

Competition from foreign countries has driven down the price paid for catfish forcing many domestic catfish farmers to leave the business of seek alternative species of fish to produce. There is a great interest among such fish farmers in producing high value species such as bass, sunfish and crappie for human consumption. However, these high value species have behaviorial characteristics that mak ...

Our goal is to develop a new largemouth bass fingerling production system/strategy that will employ "out-of-season" fall spawning of largemouth bass in raceways, followed by winter feed-training and the on-growing of advanced fingerlings indoors. The research outlined in this proposal includes three main objectives: Objective 1. Develop brood-stock acclimation facilities and protocols for out-of-s ...

The project will prove the feasibility of providing safer and more effective travel for blind individuals who live in rural communities. To that end we will:1. Determine the technologies can be used to provide geo-location information for a blind user navigating in a rural environment. While there are some "talking GPS" devices available, the mapping information provided is not adequate. Existing ...
