  1. Fundamentals and Applications of Electrically-assisted Microrolling

    3t945q88k?file=thumbnail
    Description: In this presented study, rolling in micro scale level, termed as microrolling, has been advanced and extended its application to surface texturing and roll bonding. Meanwhile, continuous direct current (DC) is introduced to the processes to establish two new microrolling processes: the Electrically-assisted Roll Bonding (EARB) and the Electrically-assisted Microrolling-based...

  2. Real-Time Algorithms for Symbol-Based Automation

    Xw42n805q?file=thumbnail
    Description: Intelligent behavior in humans is largely associated with encoding information to discrete symbols. However, symbolic behavior in robotic systems is not widespread, mainly due to lack of tools that constitute symbol-based automation implementable in real time. This thesis proposes real-time algorithms that facilitate and promote symbol-based action and sensing. In...

  5. Multi-agent Coordination by Decentralized Estimation and Control

    6395w727c?file=thumbnail
    Description: This thesis contributes in two ways. First it describes a new framework for the systematic design of collective behaviors and solves a key stability issue under this design framework. In this thesis we apply this framework to solve three tasks in the swarm robotics field: connectivity maintenance, formation control and...

  6. Vacancy Clustering Phenomena in Silcon Carbide Reactor Components: A Multiple Time-Scale Atomistic Problem

    2b88qc29j?file=thumbnail
    Description: The goal of this dissertation was to elucidate the coalescence of vacancies in the cubic polytype of silicon carbide in a nuclear reactor relevant system. Large-scale empirical potential atomistic simulations were employed and the exploration of long time-scale behavior was performed through a new application of the parallel replica dynamics...

  7. Micro/Nanoscale Friction and Application of Surface Wettability in MEMS

    Dv13zt42z?file=thumbnail
    Description: Micro/nanoscale friction behavior has drawn a great deal of attention because it can reveal friction behavior at the interface level and ultimately lead to the discovery of the origin or real mechanism of friction. Surface wettability is an important property of solid surfaces and has been widely used in fundamental...

  9. Protein Folding Under an Applied Force

    Vh53wv84h?file=thumbnail
    Description: In this thesis we study protein folding with external force. In Part I we simulate the folding or unfolding procedure based on the two-state model. For constant-velocity experiments, the simulation results fit the experimental results. For constant-force experiments, we introduce cooperativity between domains to explain the different behavior between single...

  10. SHAPE MEMORY ALLOY BASED MICRO-MESO SCALE MANIPULATOR

    Dj52w485x?file=thumbnail
    Description: The need for low-cost robust meso-scale "smart" robots (manipulators) that have no discrete parts (monolithic), no sensors ("self-sensing") and can be used in space-constrained systems, e.g., in microfactories, biomedical applications, etc., was the motivation for the current research. This study describes the design, fabrication and analysis of such a smart...
