Computerised dynamic control of an ac dynamometer

Creator:

Rodrigues, Terence Keith

Abstract:

The Motor Systems Resource Facility (MSRF) at Oregon State University presently conducts a variety of steady state tests on Motors and Generators, with ratings of upto 300Hp.(225kW), using a dynamometer. The dynamometer consists of an induction motor fed by a power electronic converter. A control computer uses a serial link,...

Masters Thesis
Testing and modeling of the single-phase Written-Pole Motor

Creator:

Chis, Lucian

Abstract:

A relatively new development in the electric machines field has been the written-pole technology, of which the latest product is the large single-phase electric motor, the single phase Written-Pole Motor (WPM). The WPM is a synchronous, permanent-magnet single-phase motor having a weak rotor cage for start-up which in addition exhibits...

An investigation of vegetation : hydrology interactions in watershed 1 at the H.J. Andrews Experimental Forest

Creator:

Bredensteiner, Kim C.

Abstract:

For management purposes, it would be useful to be able to predict streamflow response to forest practices in small, unmonitored basins. The primary objective of this study is to investigate the influence of early successional vegetation on summer streamflow levels. The long-term data records from watershed 1 at the H.J....

Fire history, fire regimes, and development of forest structure in the central western Oregon Cascades

Creator:

Weisberg, Peter J.

Abstract:

Fire history and fire regimes were reconstructed for a 450 km² area in the central western Oregon Cascades, using tree-ring analysis of fire scars and tree origin years at 137 sampled clearcuts. I described temporal patterns of fire frequency, severity, and size, and interpreted topographic influences on fire frequency and...

Characteristics and spatial relationships of day-roosts and activity areas of female long-eared myotis (Myotis evotis) in western Oregon

Creator:

Waldien, David L.

Abstract:

Management of habitat for bats requires sound information on their habitat requirements. I used radio telemetry to identify 80 roosts for 24 long-eared myotis (Myotis evotis); 74 roosts were identified for 21 females and 6 roosts for 3 males. Females primarily used dead and defective conifer trees (n=22) and conifer...
