  • COLAN V : a high performance local area network for control and communication utilizing a communication co-processor

    Creator:
    Kumar, Ravi C.
    Abstract:
    This paper describes the design and implementation of COLAN V, a High Performance Local Area Network for Communications and Control utilizing a Communications Coprocessor. The main objective of this thesis is to improve upon the performance of previous COLANs in speed, switching techniques and error detection techniques. This was possible...

  • Cluster partitioning approaches to parallel Monte Carlo simulation on multiprocessors

    Creator:
    Ranawake, Udaya A.
    Abstract:
    We consider the parallelization of Monte Carlo algorithms for analyzing numerical models of charge transport used in semiconductor device physics. Parallel algorithms for the standard k-space Monte Carlo simulation of a three band model of bulk GaAs on hypercube multicomputers are first presented. This Monte Carlo model includes scattering due...

  • Critical current distributions and the V(1) transition in Nb-Ti superconducting composites

    Creator:
    Narang, Girish
    Abstract:
    It is well established that the extended range V(I) transition behavior in filamentary superconducting composites depends strongly on the processing conditions of the composite. Based on previous work, a model proposed by Warnes et al predicts that the second derivative of the V(I) transition is related to a more fundamental...

  • Evaluation of copper to superconductor area ratio measurement techniques for niobium-titanium composite superconducting wire

    Creator:
    Pyon, Taeyoung
    Abstract:
    Measurement of the copper to superconductor ratio (Cu/SC) in composite superconducting wires is necessary for process control, quality assurance, and characterization of the final wire properties. A comparison has been made of three techniques for measuring the Cu/SC ratio on a set of commercial wires produced for the Superconducting SuperCollider...

  • Mechanics of Nb-Ti superconducting composites

    Creator:
    Guo, Zhiqiang
    Abstract:
    Mechanical behavior of Nb-Ti superconducting composites with copper matrices have been studied experimentally and theoretically. Experimental work includes extensive measurements of Cu/Nb-Ti composite system. Techniques for fine fiber testing and composite wire measurement have been developed. Experimental parameters examined in this research include geometry, hardness, Young's modulus, Poisson's ratio, yield...

  • Rheological behavior of Douglas-fir as related to the process of drying

    Creator:
    Wu, Qinglin
    Abstract:
    Large inelastic strain occurs inside a piece of lumber during drying. The strain consists of several components such as elastic, plastic, creep, shrinkage and mechano-sorptive effect. The mechanical behavior of the whole board during drying is determined by the behavior of individual strain components and their interactions. Whereas limited investigations...

  • A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

    Creator:
    Park, Heeyong
    Abstract:
    The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...

  • Three-dimensional, nonlinear viscoelastic analysis of laminated composites : a finite element approach

    Creator:
    Wang, Min
    Abstract:
    Polymeric composites exhibit time-dependent behavior, which raises a concern about their long term durability and leads to a viscoelastic study of these materials. Linear viscoelastic analysis has been found to be inadequate because many polymers exhibit nonlinear viscoelastic behavior. Classical laminate theory is commonly used in the study of laminated...
