Lidar systems offer considerable promise for the acquisition of a variety of atmospheric variables with very high spatial and temporal resolution from airborne platforms. Ground-based lidar systems have been demonstrated that measure aerosols, water vapor, and ozone, and airborne windsensing lidar have been flown on several military aircraft. The growing number of commercial airliners, however, of ...

A very simple and low-cost optical sensor for measuring vibrations of mechanically supported thin films and other small objects will be developed. Such measurements are useful in characterizing elastic materials properties. The sensor is based upon the so-called self-mixing effect in lasers, which enables the assembly of velocimeters containing nothing more than a diode laser, a lens, and a sign ...

The purpose of this Phase 1 project is to demonstrate the ability to develop a neural network model of the ceramic grinding process with fusion of the sensor/process control parameter data. A model will be developed from existing NIST data using artificial neural systems (ANS) with algorithms that have previously been specifically designed to provide good results for manufacturing applications, fo ...

The characteristics of flexural-gravity wave propagation in Arctic pack ice, including wave speed as a function of frequency and the frequency of peak energy, depend on the spatially averaged ice thickness. Thus a system which records these characteristics can be used to monitor changes in the average thickness of the pack ice. This is vital to understanding and predicting global climate change. H ...

Zeotrope refrigerant mixtures have been proposed and used for energy saving. Matching the temperature glide of the refrigerant to the temperature change of the heat sink and source, while simultaneously reducing the pressure difference seen by the compressor will result in significantly improved efficiency. A new cycle based on a mixture cascade combined with a rectifier column has recently been i ...

Phase I research proved the feasibility of EnerTech's Slurry Carbonization technology for economically producing clean and marketable fuels from high-moisture agricultural residues and wastes, especially animal manures. The Slury Carbonization technology effectively transformed low-grade animal residues, through a moderate temperature and pressure carbonization process, into a uniform and especial ...

Studies have found Cryptosporidium parvum (C. parvum) oocysts in 65-97% of surface water tested inthe United States. The current Surface Water Treatment Rule does not include analysis for C. parvum.However, the increased incidence of outbreaks involving Cryptosporidiosis have instigated aninvestigation into whether or not testing should be included in the Enhanced Surface Water TreatmentRule. Th ...

Alaskan Commercial agriculture presents many challenges including extreme weatherconditions, isolation from cost-effective distribution, and availability of plants suitable forcommercial application. Clearing requirements for agricultural tracts resulted in a loss of topsoil.Using commercial chemical fertilizers further depletes soils resulting in greater increasing soiladditive requirements. Th ...

The project will determine the technical feasibility of developing state-of-the art information system technology for districts and schools that addresses the accountability, planning, management, and evaluation functions essential to achieving comprehensive education reform and increased productivity in education. This research and development effort aims to overcome the serious lack of informat ...
