  • Modified limiting dilution analysis : a mathematical model with biological interpretation

    Creator:
    Maier, Stefan H.
    Abstract:
    A mathematical model of Limiting Dilution Analysis for two limiting parameters is presented and investigated. Limiting Dilution Analysis is a microbiological cell assay developed for immunological application. In the given case we deal with the interaction between B lymphocytes, macrophage derived factor and T-independent antigens. The state of the art...

  • Three dimensional electromagnetic FDTD simulation of general lossy structures with nonuniform grid spacing

    Creator:
    Falconer, Maynard C.
    Abstract:
    A new second order accurate nonuniform grid spacing technique which does not depend on supraconvergence is developed for Finite Difference Time Domain (FDTD) simulation of general three dimensional structures. The technique is useful for FDTD simulations of systems which require finer details in small regions of the simulation space by...

  • Mathematical modeling and the control of immune processes with application to cancer

    Creator:
    Lee, Kwon Soon
    Abstract:
    A foundation for the control of tumors is presented, based upon the formulation of a realistic, knowledge-based mathematical model of the interaction between tumor cells and the immune system. The parametric control variables relevant to the latest experimental data, e.g., the sigmoidal dose-response relationship and Michaelis-Menten dynamics, are also considered....

  • Automated analysis, design, and optimization of low noise oscillators

    Creator:
    Vytyaz, Igor
    Abstract:
    Low noise oscillators are universally needed in digital systems for clock generation and synchronization, and in radio-frequency communication front-ends for frequency up- and down-conversion. Noise in oscillators results in timing jitter, and limits the clock frequency of digital systems. In radio-frequency communication systems, phase noise in oscillators lowers the signal-to-noise...

  • Radix-4 ASIC design of a scalable Montgomery modular multiplier using encoding techniques

    Creator:
    Tawalbeh, Lo'ai
    Abstract:
    Modular arithmetic operations (i.e., inversion, multiplication and exponentiation) are used in several cryptography applications, such as decipherment operation of RSA algorithm, Diffie-Hellman key exchange algorithm, elliptic curve cryptography, and the Digital Signature Standard including the Elliptic Curve Digital Signature Algorithm. The most important of these arithmetic operations is the modular...

  • 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...

  • Analysis and modeling of planar microstrip spiral inductors on lossy substrates

    Creator:
    Lutz, Richard D.
    Abstract:
    The advent of low-cost RFIC's fabricated in Silicon-based technologies has led to the use of monolithic lumped elements which are located on-die. While it is clearly advantageous to have a high degree of integration and thus fewer off chip elements, parasitic losses due to semiconducting substrate effects can be a...

  • Functional expansions in bilinear system analysis

    Creator:
    Karanam, Veerabhadra Rao
    Abstract:
    Bilinear systems, encountered in many important applications of engineering, biological and socio-economic systems, represent the logical step in complexity between the linear systems which are inadequate in the modeling of various dynamic processes and the difficult realm of nonlinear systems. This dissertation studies two functional expansions in bilinear system analysis-...

  • Weak-supervision Time-series Analysis

    Creator:
    You, Zeyu
    Abstract:
    Efficient time-series analysis can impact multiple application domains such as motif discovery in gene analysis or music data, extracting spectro-temporal patterns in acoustic scene analysis, or annotating and classifying electrical bio-signals (such as ECG, EEG, and EMG) for medical applications. Time-series analysis involves a variety of tasks. To predict future...

  • Broadband modeling of on-chip transformers for silicon RFICs

    Creator:
    Rapolu, Kavitha
    Abstract:
    Magnetically coupled passive transformers are increasingly integrated on-chip for various analog and radio frequency (RF) applications including direct current (DC) isolation, impedance transformation/matching, and conversion between single-ended and differential signals. A primary motivation for the on-chip integration of transformers is the overall size reduction and reduced cost. However, the performance...
