Substrate coupling in integrated circuits is the process whereby parasitic current flow in the substrate electrically couples devices in different parts of the circuit. Higher levels of integration and higher frequencies of operation make the coupling more pronounced in modern circuit realizations. High levels of integration are desirable in several applications for reducing the overall power d...

In the present work, FGM shells integrated with magnetostrictive layers acting as distributed sensors and actuators are modeled to control vibration attenuation of FGM shells with simply supported boundaryconditions. To achieve a mechanism for actively control of the oscillation amplitude of the integrated structure, a negative velocity proportional feedback control law is implemented in the st...

Abstmct-Measurements of thermal conductivity on conventional and newly developed electronic ceramics are presented as part of an effort to incorporate the new high thermal conductivity ceramics into microcircuit manufacturing. Motivated by large variations in values claimed by different vendors for ostensibly similar materials, a longitudinal bar apparatus was built to measure thermal conductiv...

We present a computational model of how verbs might be learned within the limited domain of hand actions We hypothesize that such verbs refer to the activities of underlying motor schemas and leverage this constraint to build a system with strong enough biases that it can learn from a reasonably small number of examples while still having adequate exibility to learn the hand action verbs of any...

The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. The problem of scheduling the individual parts of a control algorithm is studied. It is shown how s...

To satisfy the quality of service requirements of real-time multimedia applications, networks must employ resource reservation and admission control. In this paper, we describe a new Measurement-Based Admission Control (MBAC) algorithm that uses empirical traac envelopes of the aggregate traac ow to allocate network resources. Our framework of traac envelopes provides a robust and accurate char...
