  • New methods for finite field arithmetic

    Creator:
    Yanik, Tuğrul
    Abstract:
    We describe novel methods for obtaining fast software implementations of the arithmetic operations in the finite field GF(p) and GF(p[superscript k]). In GF(p) we realize an extensive speedup in modular addition and subtraction routines and some small speedup in the modular multiplication routine with an arbitrary prime modulus p which...

  • Fabrication and characterization of ACTFEL devices

    Creator:
    Keir, Paul D.
    Abstract:
    The goal of this thesis is the identification and synthesis of high-luminance, primary color alternating-current thin-film electroluminescent (ACTFEL) devices. Special attention is paid to the synthesis of primary color green ACTFEL devices because of the lack of an adequate primary green ACTFEL phosphor and the dominance of green wavelengths in...

  • Modeling and characterization of multiple coupled lines

    Creator:
    Tripathi, Alok
    Abstract:
    A configuration-oriented circuit model for multiple coupled lines in an inhomogeneous medium is developed and presented in this thesis. This circuit model consists of a network of uncoupled transmission lines and is readily modeled with simulation tools like LIBRA© and SPICE©. It provides an equivalent circuit representation which is simple...

  • Characterization of organic light-emitting devices

    Creator:
    Norris, Benjamin J.
    Abstract:
    In this thesis steady-state (i.e. steady-state with respect to the applied voltage waveform) transient current-transient voltage [i(t)-v(t)], transient brightness-transient current [b(t)-i(t)], transient brightness-transient voltage [b(t)-v(t)], transient current [i(t)], transient brightness [b(t)], and detrapped charge analysis are introduced as novel organic light emitting device (OLED) characterization methods. These analysis methods involve...

  • Energy-efficient, short-range ultra-wideband radio transceivers

    Creator:
    Hu, Changhui
    Abstract:
    Short-range wireless communications continually attract interest from both industry and academia, and it is changing our life in every aspect in the last decade. The design of wireless transceivers is the bottleneck for variety applications, due to RF modeling inaccuracy, stringent FCC regulations over the transmitted power spectrum, interference, multi-path...

  • ACTFEL device simulation with impact ionization using a two-sheet charge model

    Creator:
    Bouchard, Anthony F.
    Abstract:
    The main achievement of this thesis is the development of a two-sheet charge simulation model with space charge creation by trap-to-band impact ionization to describe the electrical characteristics of alternating-current thin-film electroluminescent (ACTFEL) devices. The two-sheet charge model localizes all of the space charge in the phosphor region of an...

  • Prototyping a scalable Montgomery multiplier using field programmable gate arrays (FPGAs)

    Creator:
    Mhaidat, Khaldoon
    Abstract:
    Modular Multiplication is a time-consuming arithmetic operation because it involves multiplication as well as division. Modular exponentiation can be performed as a sequence of modular multiplications. Speeding the modular multiplication increases the speed of modular exponentiation. Modular exponentiation and modular multiplication are heavily used in current cryptographic systems. Well-known cryptographic...

  • Electro-optical characterization of SrS:Ce, SrS:Cu, and SrS:Cu,Ag alternating-current thin-film electroluminescent devices

    Creator:
    Grudzinsky, Arkady S.
    Abstract:
    The purpose of this thesis is to contribute to the understanding of SrS-based alternating-current thin-film electroluminescent (ACTFEL) device operation. Three main accomplishments serving this purpose are presented in this thesis. First, two new methods are developed for estimation of insulator capacitance in ACTFEL devices possessing a large amount of dynamic...

    Creator:
    Kness, Philip J.
    Abstract:
    Several hardware-based security improvements to Near Field Communication (NFC) and Radio-Frequency Identification (RFID) systems are developed and presented. The improvements are intended to be used in conjunction with software encryption to ensure robust security. Two main implementations for a more secure NFC or RFID system are presented: a jamming system,...

  • Time domain modeling of electromagnetic radiation with application to ultrafast electronic and wireless communication

    Creator:
    Remley, Catherine A.
    Abstract:
    A versatile computational technique for improved time domain modeling of electromagnetic radiative systems is demonstrated. Two computational methods are combined: the finite-difference time domain (FDTD) method, a full-wave electromagnetic field solver, and the Kirchhoff surface integral formulation, a spatial transformation technique. The combined FDTD/Kirchhoff technique is shown to increase accuracy...
