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 product design optimization has developed and demonstrated a variety of modeling techniques and solution methods, including multidisciplinary design optimization. As new techniques migrate to the industrial world engineers are faced with much more complex problems often extending beyond their realm
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
This thesis introduces a fault injector, called “Pulad”, specifically developed for finding application vulnerabilities. Most previous approaches for finding application vulnerabilities involved static verification methods. With these methods, the source code is not executed. Since vulnerabilities can only be revealed when they
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
Accurate, low-cost, rapid-prototyping techniques for analog circuits have been a long awaited dream for analog designers. However, due to the inherent nature of analog system, design automation in analog domain is very difficult to realize, and field programmable analog arrays (FPAA) have
Increasing electronic product manufacturing volumes and cooling requirements necessitate the use of new materials and innovative techniques to meet the thermal management challenges and to contribute towards sustainable development in the electronic industry. Thermally conductive polymer composites, using high thermal conductivity fillers
As the gate oxide thickness of the metal-oxide-semiconductor (MOS) Field Effect Transistor (FET) is continuously scaled down with lateral device dimensions, the gate leakage current during operation increases exponentially. This increase in leakage current raises concerns regarding device reliability. Substitute dielectrics with
Detailed analysis of a 4H-SiC MOSFET has been carried out by numerically solving the steady state semiconductor Drift-Diffusion equations. Mobility models for bulk phonon scattering, surface phonon scattering, surface roughness scattering, Coulomb scattering by interface traps and oxide charges, and high field
