  • Deep ultraviolet solid-state laser development

    Creator:
    Dutton, David A. (David Adam)
    Abstract:
    There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...

  • New configurations of bandpass filters in single and multilayer environment

    Creator:
    Gururajan, Kala
    Abstract:
    Mobile and telecommunication industry has experienced tremendous growth in the recent past. Miniaturization and increased functionality have become necessary for all passive components in the system. Bandpass filters are critical passive components in any communication system and the existing designs in the crucial 1-10 GHz bandwidth suffer many drawbacks. For...

  • A direct-drive wave energy converter with contactless force transmission system

    Creator:
    Agamloh, Emmanuel B.
    Abstract:
    Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

  • Fiber Bragg grating-tunable diode laser

    Creator:
    Ericksen, Doug
    Abstract:
    Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the development and fabrication of such a device. An introduction is given describing applications of tunable lasers and some of the different methods of creating a tunable diode...

  • Leakage power minimization by considering self-bias transistor and pin reordering technique

    Creator:
    Gopalakrishnan, Harish
    Abstract:
    Recent trends in CMOS technology and scaling of devices clearly indicate that leakage power in digital circuits would be crucial and largely depend on the sub-threshold current. Minimizing leakage is gaining increasing importance along with other critical design aspects primarily due to the growing demand for portable battery-operated electronic devices...

  • High-speed CMOS dual-modulus presalers for frequency synthesis

    Creator:
    Desikachari, Ranganathan
    Abstract:
    Phase-locked loop (PLL) frequency synthesizers lie at the heart of most radio transceivers. An important objective of the electronics and communications industry is to design high-speed building blocks which dissipate the lowest possible power, and to ac- complish this with the cheapest technology. The dual-modulus prescaler is one of the...

  • Performance of MC-CDMA with pilot code and blind equalization algorithm

    Creator:
    Lesmana, Joseph Sam
    Abstract:
    Various methods and techniques have been introduced and applied to advance the state of the art of mobile wireless communications technology. For example, some techniques are applied to overcome the problem of multipath caused by the mobile environment. Multipath produces replicas of the wanted signal which arrive at the receiver...

  • Information foraging in debugging

    Creator:
    Lawrance, Joseph A.
    Abstract:
    Programmers spend a substantial fraction of their debugging time by navigating through source code, yet little is known about how programmers navigate. With the continuing growth in size and complexity of software, this fraction of time is likely to increase, which presents challenges to those seeking both to understand and...

  • Novel design and implementation of a permanent magnet linear tubular generator for ocean wave energy conversion

    Creator:
    Prudell, Joseph H.
    Abstract:
    The world’s energy consumption is growing at an alarming rate and the need for renewable energy is apparent now more than ever. Estimates have shown that optimization of the extraction of energy from the ocean could significantly aid the world’s quest for sustainable and affordable energy services for all. From...

  • Methods to improve the reliability and resiliency of near/sub-threshold digital circuits

    Creator:
    Crop, Joseph A.
    Abstract:
    Energy consumption is one of the primary bottlenecks to both large and small scale modern compute platforms. Reducing the operating voltage of digital circuits to voltages where the supply voltage is near or below the threshold of the transistors has recently gained attention as a method to reduce the energy...
