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 ...

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 ...

This project will demonstrate the technical merit and feasibility of Transition AbleAideTM, a needs-based system for assisting special educators and related service providers in matching students with disabilities with appropriate disability accommodations (including assistive technology, home automation devices, and other simple accommodations) to aid the transition from school to adult life, but ...

The adverse acoustical environments typically found in classrooms have led to the development and proliferation of a new generation of small sound systems usually referred to as "sound field systems" (SFS). Recent studies support the usefulness of SFS to enhance the intelligibility of teachers' voices for the benefit of students with mild unaided hearing losses or attention deficits, and normally ...

Performance of US students in mathematics and physics has been limited, partly because the traditional pedagogy relies on logical and linguistic methods of teaching, and students are primarily assessed on fact knowledge and discrete skills. Recent achievements in computer science provide revolutionary means for educational reform. Thus, use of the World Wide Web and Java - a package of a new obj ...
