General pole number model for the brushless doubly-fed machine

Creator:: Boger, Michael S.
Abstract:: The Brush less Doubly-Fed Machine (BDFM) has the potential to be a more cost effective replacement for conventional induction or synchronous machine drives. The BDFM has two stator windings: a power winding and a control winding. An electronic power converter of variable voltage and frequency is connected to the control...

Renewable Energy in the Pacific Northwest - Technical and Economic Analysis of 100% Renewable Portfolios, including Seasonality Impacts and Potential Applications of Energy Storage

Creator:: Harpool, Scott
Abstract:: Renewable electrical energy sources are relatively easy to integrate at moderate penetrations, utilizing a combination of technical and market methods to increase grid flexibility. However, integrating high renewable portfolios is more challenging, and the optimal combination of resources will vary depending on the features of specific geographic areas. This study...

Three dimensional electromagnetic FDTD simulation of general lossy structures with nonuniform grid spacing

Creator:: Falconer, Maynard C.
Abstract:: A new second order accurate nonuniform grid spacing technique which does not depend on supraconvergence is developed for Finite Difference Time Domain (FDTD) simulation of general three dimensional structures. The technique is useful for FDTD simulations of systems which require finer details in small regions of the simulation space by...

Development of leadership and design skills among ECE juniors and graduate students

Creator:: Luo, Ding
Abstract:: Engineering students spend a significant amount of their undergraduate careers focused on technical theory and practice. This intensive student prepares them for their technical challenges in the future. This training is so intense that often the more 'soft skills' such as communication, leadership, design, and troubleshooting are left out or...

A survey of power systems vulnerability and failures on the Pacific Northwest due to natural disasters with a focus on volcanic activity.

Creator:: Tafempa Messa, Winnie
Abstract:: Electricity is at the center of attention as today many essential systems (water, gas, communications, and the internet for example) and infrastructures depend on its continuity for their smooth functioning. On the other hand, electricity power networks have developed and became large, and highly complex technical systems, geographically extended, requiring...

Pattern recognition of speech using hybrid computer feature extraction

Creator:: Herr, Alan Jack
Abstract:: Most technological problems associated with man-machine conversations have been solved and are well documented in both the contemporary technical and lay literature. The major remaining technological problem is the real time conversion of a human's vocal uterances into a "written" phoneme sequence representing the information content of speech. The work...

A comprehensive integration of first year engineering education

Creator:: Shuman, Matthew W.
Abstract:: Retention of engineering students is a problem for many universities, especially during the first year. The problem of introducing students to engineering while increasing retention rates has recently been addressed by many different universities. Implementing novel lab structures, adjusting the lecture to incorporate more effective teaching techniques, and using orientation...
