In this research we propose a highly predictable, low overhead and yet dynamic, memory allocation strategy for embedded systems with scratch-pad memory. A scratch-pad is a fast compiler-managed SRAM memory that replaces the hardware-managed cache. It is motivated by its better real-time
Pre-execution is a novel latency-tolerance technique where one or more helper threads run in front of the main computation and trigger long-latency delinquent events early so that the main thread makes forward progress without experiencing stalls. The most important issue in pre-execution
The performance of demand-driven caching is known to depend on the locality of reference exhibited by the stream of requests made to the cache. In spite of numerous efforts, no consensus has been reached on how to formalize this notion, let alone
Several trends in technology have important implications for embedded systems of the future. One trend is the increasing density and number of transistors that can be placed on a chip. This allows designers to fit more functionality into smaller devices, and to
This thesis presents a theoretical and experimental comparison of polymerization induced by microwave energy and polymerization induced by thermal energy of the resin bisphenol A-glycidyl methacrylate used in restorative dentistry. The question of whether microwave interaction with the polymer is microwave heating
This dissertation focuses on the collaborative control of homogeneous UAV swarms. A two-level scheme is proposed by combining the high-level path planning and the lowlevel vehicle motion control. A decentralized artificial potential function (APF) based approach, which mimics the bacteria foraging process,
Research in the University of Maryland Gyroklystron program has centered around the development of a 17.136 GHz gyroklystron, that combines the gyrotron mechanism with the ballistic bunching of klystrons to produce a high power, high gain amplifier. The current tube is a
Hysteresis is a natural phenomenon existing in many systems. Binary hysteresis is the simplest yet important model to study electronically generated hysteresis. Binary hysteresis circuits, the Schmitt trigger being an example, are widely used in reducing noise sensitivity, designing oscillators, generating chaotic
A closed-loop control system with photodiode position sensors has been implemented in a microball bearing supported linear electrostatic micromotor to improve accuracy and reliability. The fabrication sequence of the previously developed micromotor was modified to integrate a photodiode-based position sensing mechanism. Proportional
