Nonlinear Variants Of The Least Mean Square (Lms) Algorithm, John George Van Saders

Theses

Adaptive systems using the LMS algorithm or its variants usually require bilinear correlation multipliers with high dynamic range and large bandwidth. The class of LMS-type algorithms utilizing zero-memory limiters (on one or both correlation multiplier inputs) to reduce dynamic range are examined. The correlator limiters may be included to simplify the hardware implementation or may arise due to limited dynamic range of the loop components. The application of a theorem due to Price provides a technique for simplifying the analysis, which otherwise might be extremely difficult. The analysis provides closed-form expressions for the mean weight convergence behavior, permitting examination of …

The Effects Of Degraded Indoor Air Quality On Employees Working In High Rise Office Buildings, Richard Patrick Luongo

Theses

An examination of the effects of poor indoor air quality on workers in high rise office buildings was conducted. These effects are manifested physiologically, psychologically and economically and originate from sources inside and outside the building, as well as from the building's ventilation system. These sources include combustion products, microorganisms, volatile organic chemicals, cigarette smoke and miscellaneous chemicals. Lower productivity and higher absenteeism are the initial results of these effects. If the situation becomes chronic, an erosion of trust between employer and employee can occur which may eventually serve as the basis for litigation, such as worker's compensation claims and …

A Graphic Identity Program For The Thousand Acre Swamp Sanctuary, Cynthia B. Hummel

Theses

People have often failed to appreciate the significance of wetlands. Lack of awareness has caused wetlands to be drained, filled, and polluted, to meet shortterm human needs. One half of the original 215 million acres of wetlands in the United States no longer exist. Best estimates indicate that we are continuing to loose 458,000 acres of our remaining wetlands each year. Wetlands have an enormous ability to produce and support plant and animal life. They rank among the most productive ecosystems in the world, and produce as much plant growth as tropical jungles, and 20 times as much plant material …

A Study Of Ink Trapping Comparing Gravimetric And Densitometric Methods Of Measurement, Jui-Lin Hsu

Theses

In 1958, Preucil suggested an equation to calculate ink trap based on measurements of a printed sheet with a densitometer. Preucil's equation was based on the additivity rule and the proportional rule. However, these rules do not hold in all cases. Several alternative equations have been suggested. This study intends to examine the effectiveness of three ink trap equations using densitometry by means of comparing the calculated values to those measured by the gravimetric method. An attempt is also made to estimate the value of maximum printable density, Dm, in Hamilton's equation. The theoretical basis of each equation is briefly …

An Investigation Of Electrophoresis Gel Silver Staining Using Large Area Sample Inclusive Polymerization, Lloyd C. Litt

Theses

An electrophoresis silver stain was investigated using a unique method of sample introduction in polyacrylamide gel media. A protein inclusive polymerization technique is described that produces large area gels with controlled protein concentration steps. Using gels with Bovine Serum Albumin sample steps, an organic dye stain, Coomassie Brilliant Blue was found to be extremely linear in stain response. When used on a published silver stain (Merril,et. al.) a non-linearity caused by a diffuse background density was observed.
