  • Improving the Karatsuba-Ofman multiplication algorithm for special applications

    Creator:
    Erdem, Serdar S.
    Abstract:
    In this thesis, we study the Karatsuba-Ofman Algorithm (KOA), which is a recursive multi-precision multiplication method, and improve it for certain special applications. This thesis is in two parts. In the first part, we derive an efficient algorithm from the KOA to multiply the operands having a precision of 2[superscript...

  • Special associative preprocessing structures for qualitative feature extraction

    Creator:
    Bibby, Michael C.
    Abstract:
    Existing pattern recognition and classification algorithms in computer vision require vast amounts of computations on input data. As a result, memory access time is a critical parameter in system performance. Tremendous parallelism in structure and algorithm is required for the system to operate in real-time. A preprocessing structure for qualitative...

  • Energy-efficient routing for delay-constrained data traffic in linear wireless sensor networks

    Creator:
    Alesaimi, Hani
    Abstract:
    Linear wireless sensor networks (LWSN) are special class of wireless sensor networks where sensor nodes are deployed in a straight line. Monitoring industrial pipelines, railroads, tunnels, power lines, and borders are applications of LWSNs. Wireless sensors are tiny devices with limited energy resources; therefore, efficient energy routing in LWSNs is...

  • Oscillators and phase locked loops for space radiation environments

    Creator:
    Vandepas, Martin
    Abstract:
    Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...

  • Designing a high level microprogramming language

    Creator:
    Malik, Kamran
    Abstract:
    The purpose of this research is to design a high level language (HLL) suitable for microprogramming. A top down design technique has been adopted which makes the language design process simple and accurate. The primitive operations of a high level language for producing emulators is shown to include special purpose...

  • Growth, fabrication and testing of pseudomorphic P-channel GaAs/InGaAs/AlGaAs MODFETS

    Creator:
    Schulte, Donald W.
    Abstract:
    This thesis reports on the growth and characterization of p-type pseudomorphic A1GaAs /InGaAs /GaAs modulation doped field effect transistor (MODFET) structures. A series of different p-type MODFET structures were grown with a systematic variation of the indium mole fraction and quantum well width of the InGaAs channel region. Extensive characterization...

  • Design and computer aided optimization of a fully integrated CMOS RF distributed amplifier

    Creator:
    Ballweber, Brian M.
    Abstract:
    Advancements in the sophistication and complexity of modern electronic systems are creating a need for highly integrated systems with ever higher operational frequencies. The economical demands of these systems dictate that they be implemented using low cost fabrication technologies, such as digital CMOS. One of the major challenges facing circuit...

  • Rapid hardware implementations of classical modular multiplication

    Creator:
    Johnson, Scott Andrew
    Abstract:
    Modular multiplication is a mathematical operation fundamental to the RSA cryptosystern, a public-key cryptosystem with many applications in privacy, security, and authenticity. However, cryptosecurity requires that the numbers involved be extremely large, typically ranging from 512-1024 bits in length. Calculations on numbers of this magnitude are cumbersome and lengthy; this...
