The Analysis And Modeling Of Fine Pitch Laminate Interconnect In Response To Large Energy Fault Transients , Joel Arlen Jorgenson Jan 1998

The Analysis And Modeling Of Fine Pitch Laminate Interconnect In Response To Large Energy Fault Transients , Joel Arlen Jorgenson

Retrospective Theses and Dissertations

In embedded applications, the miniaturization of circuitry and functionality provides many benefits to both the producer and consumer. However, the benefits gained from miniaturization is not without penalty, as the environmental influences may be great enough to introduce system failures in new or different modes and effects;Of particular interest within this research is the effect of fault transients in reduced geometries of printed circuit card interconnect, commonly referred to as fine pitch laminate interconnect. Whereas larger geometries of conductor trace width and spacing may have been immune to circuit failure at a given fault input, the reduction of the ...


Service Identification And Allocation In Market-Based Power System Operation , Jian Fu Jan 1998

Service Identification And Allocation In Market-Based Power System Operation , Jian Fu

Retrospective Theses and Dissertations

In the market-based power system operation environment, ancillary services and other interconnected services are necessary to to maintain the secure and reliable operation of the transmission system. Service identification and allocation, together with congestion management, become important functions in the day- ahead scheduling of the independent system operator (ISO);In this dissertation, a general framework for service identification and congestion management was proposed. Based on a set of market model assumptions and the anticipated behaviors of the market participants, the individual profits of the market participants were analyzed. An overall profit maximization was proposed as the desired objective function. Because ...


High Performance, Point-To-Point, Transmission Line Signaling, André Dehon, Thomas F. Knight Jr. Jan 1998

High Performance, Point-To-Point, Transmission Line Signaling, André Dehon, Thomas F. Knight Jr.

Departmental Papers (ESE)

Inter-chip signaling latency and bandwidth can be key factors limiting the performance of large VLSI systems. We present a high performance, transmission line signaling scheme for point-to-point communications between VLSI components. In particular, we detail circuitry which allows a pad driver to sense the voltage level on the attached pad during signaling and adjust the drive impedance to match the external transmission line impedance. This allows clean, reflection-free signaling despite the wide range of variations common in IC device processing and interconnect fabrication. Further, we show how similar techniques can be used to adjust the arrival time of signals to ...


Safe Cooperative Robotic Patterns Via Dynamics On Graphs, Robert W. Ghrist, Daniel E. Koditschek Jan 1998

Safe Cooperative Robotic Patterns Via Dynamics On Graphs, Robert W. Ghrist, Daniel E. Koditschek

Departmental Papers (ESE)

This paper explores the possibility of using vector fields to design and implement reactive schedules for safe cooperative robot patterns on graphs. The word "safe" means that obstacles - designated illegal portions of the configuration space - are avoided. The word "cooperative" connotes situations wherein physically distributed agents are collectively responsible for executing the schedule. The word "pattern" refers to tasks that cannot be encoded simply in terms of a point goal in the configuration space. The word "reactive" will be interpreted as requiring that the desired pattern be asymptotically stable: conditions close but slightly removed from those desired remain close and ...
