Pneumatic Particulate Collection System Analysis and Design
A pneumatic particulate collection system harnesses the energy associated with the release of a compressed gas to transport particulate to a collection chamber. In an effort to improve the efficiency of a previously designed collection system, high speed imaging in conjunction with computational …

CSADP, a classical control system analysis and design package
The Control System Analysis and Design Package (CSADP) is a computer-aided design package for applying classical control system analysis and design tools to experimental frequency response measurements. CSADP allows the user to analyze and manipulate measured frequency response data, design control …

System analysis and design of a low-cost micromechanical seeker system
Precision guided targeting systems have been in use by the U.S. military for the last half-century. The desire for high targeting accuracies while maintaining minimal collateral damage has driven the implementation of guidance systems on a myriad of different platforms. Current seeker systems using …

Newton: Computer system improvement through comparative macroperformance analysis
In recent years, computer systems with complex architectural features have been designed and built without a complete understanding of the performance impact of the features. All current systems with complex architectures deliver only a small fraction of their theoretical peak performance on all …

Small-signal analysis of parallel power converters
A small-signal analysis and modelling approach is developed for parallel power converter modules. The small-signal model of parallel buck converter modules is developed in detail to demonstrate the modelling approach. It is shown that a multiple power converter module system can be reduced to an …

Homotopy algorithms for the H² and the combined H²/H<sup>∞</sup> model order reduction problems
… order model, optimal in the H² sense, to a given system model is a fundamental one in control system analysis and design. The addition of a H<sup>∞</sup> constraint to the H² optimal model reduction problem results in a more practical yet computationally more difficult problem. Without the global …

A Case Study in the Participatory Design of a Collaborative Science-Based Learning Environment
… technology research studies have found computer and software technologies to be underutilized in U.S. classrooms. In general, many teachers have had difficulty integrating computer and software technologies into learning activities and classroom curricula because specific technologies are …

Stochastic modelling for control and interconnections of biological systems
… At this scale, reactions are inherently discrete and stochastic. Traditional models based on differential equations and mass-action kinetics fail to capture the behaviour of such systems. In contrast, stochastic models can suffer the curse of dimensionality, complicating system analysis and design …

Integrated Design of Electrical Distribution Systems: Phase Balancing and Phase Prediction Case Studies
Distribution system analysis and design has experienced a gradual development over the past three decades. The once loosely assembled and largely ad hoc procedures have been progressing toward being well-organized. The increasing power of computers now allows for managing the large volumes of data …

Application of Systems Engineering Analysis Methods to Examine Engineering Transfer Student Persistence
The demand for engineering graduates in the United States continues to grow, yet the number of students entering post-secondary education is declining, and graduation rates have seen little to no change over the last several decades. Engineering transfer students are a growing population and can …

Design and evaluation of a list gathering tool in a web-based collaborative environment
… knowledge relative to the problem. Software was designed to provide relationships among and comparisons of the contributions in a "list" structure, so that individual members of a group process will be able to understand the contributions of information made by the group as a whole. A List …

Dynamical system modeling of a micro gas turbine engine
… demo engine developed for this research has low and diabtic component performance and severe heat transfer from the turbine side to the compressor side. The goals of this thesis are developing a dynamical model and providing a simulation platform for predicting the microengine performance and …
