The harmonic problem in power systems is gaining more attention as incidences correlated with harmonics increase. Conventional passive filtering techniques for harmonic mitigation have inherent problems, and purely active filters have the disadvantages of higher costs and ratings. Hybrid active filters inherit the efficiency of passive filters and the improved...
Riparian areas are an integral component of fluvial ecosystems. The management of Oregon's riparian areas has come under greater scrutiny since that latest revision of the Oregon Forest Practices Act (1994). Many riparian areas lie within forested areas. Riparian management issues such as anadromous fish population decline and large woody...
This project aims at building a Java application and a Java applet that would simulate a Stern-Gerlach laboratory in Quantum Mechanics. The project provides a tool for allowing the student to quickly design and run on the computer screen a number of experiments involving spin systems. This application could be...
A Cost-Effectiveness Analysis of a targeted intervention for community control of Ascariasis was carried out in three rural communities near Quito, Ecuador. Targeted treatment with Paico (Chenopodium ambrosioides) and Albendazole (ABZ) was applied to children aged 5 to 15 years attending primary local schools in Aglla, Checa and Iguinaro. Prevalence...
The purpose of this study was to describe the presidential search process at a
newly created community college and to learn how that process reflected the
emerging organizational culture. A single research question guided the inquiry: How
did the presidential search process at a newly created community college reflect the...
Power quality has become an important concern to both electric utilities and
end users due to the increased use of non-linear loads in modem power systems
over the past decade. Nonlinear loads inject harmonics into the power system and
thus may lead to poor power quality and lower power factor....
