THERE IS A NEED TO IMPROVE RECEPTION OF AND SYNCHRONIZATION OF WIDEBAND SIGNALS OF UNKNOWN PARAMETERS. FURTHER DEVELOPMENT OF THE MATHEMATICAL THEORY OF THE ESTIMATION OF GENERATOR CONFIGURATIONS FROM THEIR OUTPUTS WILL HELP TO ACCOMPLISH THIS GOAL. A PROMISING APPROACH IS TO APPLY SHIFT-AND-ADD AND OTHER PROPERTIES OF LINEAR SEQUENCES TO THE DETERMINATION OF THE GENERATOR CONFIGURATION. A PROPOSE ...

Arsenic contamination of groundwater is a problem facing many areas of the United States and the rest of the world. This problem has been highlighted by the U.S. Environmental Protection Agency¿s decision to mandate reductions in the acceptable level of arsenic in drinking water from 50 ppb to 10 ppb by the year 2006. In South Dakota alone, 18.6 percent of small and rural water supply systems w ...

We hypothesize that the use of SanFlow (aka polynitroxylated pegylated hemoglobin; PNPH) will ultimately translate to the reduction of mortality and morbidity, including post-traumatic stress disorder, from battle field traumatic brain injury (TBI). Towards that end, the present SBIR Phase 1 proposal will provide safety and efficacy results of SanFlow in a new guinea pig model of traumatic brain i ...

An ideal therapeutic for traumatic brain injury (TBI) accompanied by hemorrhagic shock (HS) should serve both as a resuscitation fluid to restore perfusion pressure while directly protecting the brain from secondary injury. Previous work in mice demonstra

Reconfigurable authentication unit for reading security codes printed onto parts. Our technology uses upconverting nanoparticles (UCNPs) to print durable security codes onto authentic products. We have developed a working reading apparatus that can scan codes printed onto objects with the dimensions of a credit card. This proposal will support development of a reader apparatus that is versatile en ...

Thin walled nickel alloys in exhaust sections of USAF propulsion systems are prone to cracking. Traditional repairs result in distortion and require post heat treatment. Needed is a method of repair that eliminates distortion and is mechanically, microstructurally, and chemically stable in engine exhaust environments. VRC Metal Systems (VRC) and the South Dakota School of Mines and Technology (SDS ...

NanoCoatings, Inc. (NCI) and South Dakota School of Mines & Technology (SDSMT) propose to demonstrate a unique high-voltage anodize process, Plasma Electrolytic Oxidation (PEO), to produce crystalline-oxide conversion surfaces on Al-alloy (e.g., 2024 Al) and Ti-alloy surfaces that provide comparable or higher corrosion and wear-resistance over hard Chromium (Cr) plating. The intended application i ...

There are two main objectives that this proposal addresses. The first is to develop an oil additive that reduces friction and is thermally conductive and designed to increase engine efficiency and equipment lifecycles. This will be obtained through further material production and testing. Once the desired thermal conductivity and friction coefficient is achieved, the oil additive will be tested at ...

Sate of the art aircraft composite and coating technology are not electrically conductive and may allow for a dangerous electrical charge buildup and may fail to protect from lightning strikes. Current epoxy composites used in aircraft such as the V-22 Osprey require a metal mesh to be embedded in the composite. This mesh makes repairs very difficult. Other solutions such as metallic nanoparticles ...

There are two main objectives that this proposal addresses. The first is to determine the alloy compound ratio, such as Si, Al, Fe, Sn, Mn etc. at what ratio our alloy provides the best performance to cost benefit for the Air Force. We will partner with the Air Force to perform anode testing to determine if the concept works. The anode will also be tested at SDSM&T for capacity and number of circl ...
