  • Engineering design and analysis of pipe ramming installations

    Creator:
    Meskele, Tadesse
    Abstract:
    The trenchless technology known as pipe ramming for construction of culverts and buried pipes under roadways or other infrastructure has gained significant popularity due to its cost-effectiveness and ability to alleviate surface disruptions associated with open-cut trenching. Although the experience with pipe ramming is increasing, there has been remarkably little...

  • Design Techniques of High-Speed Silicon Photonics Transceiver

    Creator:
    Li, Hao
    Abstract:
    The rapid scaling of network bandwidth and data center throughput has motivated the wide adoption of high speed transceivers. Silicon photonics (Si-Photonic) is one of the most promising techniques to realize tightly integrated optical transceivers for next-generation high speed I O standards. This dissertation focuses on the design techniques of...

  • Distributed architecture and fast parallel algorithms in real-time robot control

    Creator:
    Binder, Eli Eliyahu
    Abstract:
    Control algorithms for accurate and fast moving robots require the use of the complete dynamic model of the robot. The complete dynamic model takes into account the nonlinearity and coupling terms of the whole structure. The time of computing the dynamic equations determines whether they are usable in practical applications....

  • Use of the exergy concept for design improvement of heat exchangers and heat exchanger networks

    Creator:
    Ranasinghe, Jatila
    Abstract:
    The second law of thermodynamics, through the exergy concept, allows us to quantify and rationally cost the consumption of exergy (irreversibility) used to drive the heat exchange process and the effluent losses of exergy in a heat exchanger For systems with a network of heat exchangers, the exergy concept recognizes...

  • Embedded passives in a multilayer medium

    Creator:
    Seo, Yongseok, 1958-
    Abstract:
    Recent advances in high density low cost RF and microwave three dimensional integration technologies using LTCC(Low Temperature Cofired Ceramics), laminate and other multilayer hybrid and integrated circuits have increased interest in the design of embedded passive components such as inductors, capacitors and filters. The purpose of this study is to...

  • Power-efficient two-step pipelined analog-to-digital conversion

    Creator:
    Lee, Ho-Young
    Abstract:
    Hand-held devices are among the most successful consumer electronics in modern society. Behind these successful devices, lies a key analog design technique that involves high-performance analog-to-digital conversion combined with very low power consumption. This dissertation presents two different approaches to achieving high power efficiency from a two-step pipelined architecture, which...

  • Design techniques for clocking high performance signaling systems

    Creator:
    Hanumolu, Pavan Kumar
    Abstract:
    Scaling of CMOS technology has progressed relentlessly for the past several decades. In order for this unprecedented scaling to benefit the performance of large digital systems, the communication bandwidth between integrated circuits (ICs) must scale accordingly. However, interconnect technology does not scale as aggressively, making communication between chips the major...

  • Design of a single lamina for a microchannel dialyzer with a focus on bubble removal

    Creator:
    Mohammadi, Mahshid
    Abstract:
    A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...

  • Simultaneous beta/gamma digital spectroscopy

    Creator:
    Farsoni, Abdollah T.
    Abstract:
    A state-of-the-art radiation detection system for simultaneous spectroscopy of beta-particles and gamma-rays has been developed. The system utilizes a triplelayer phoswich detector and a customized Digital Pulse Processor (DPP) built in our laboratory. The DPP board was designed to digitally capture the analog signal pulses and, following several digital preprocessing...

  • Cathode development and reactor design for scaling-up microbial fuel cells

    Creator:
    Janicek, Anthony M.
    Abstract:
    Developing new wastewater treatment technologies which will off-set the high-energy cost associated with treatment is necessary to maintain both water and energy security. Microbial fuel cell technology represents one such option. However, there are still many obstacles to overcome before practical application of this technology can be realized. Improving cathode...
