  • 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....

  • Restoration of quadratically distorted images

    Creator:
    Kwon, Tae-hwan
    Abstract:
    The problem of the restoration of quadratically distorted images is considered in this investigation, based upon the fact that images formed by partially coherent illuminations are related quadratically to the amplitude of the object. Two of the most important problems in image restoration are: 1) determining the degradation characteristics of...

  • Nonlinear approach to the direction finding problem in array processing

    Creator:
    Ill-keun Rhee
    Abstract:
    In sonar or radar array processing, one of the most important objectives is to estimate the angles of incidence of distant source signals in a noisy environment. The standard eigenstructure-based method, which is known to yield high resolution spectral estimates for solving the direction finding problem, relies on the assumption...

  • The architecture of VIS multimedia extension

    Creator:
    Kwon, Young-Kyong
    Abstract:
    In the past, multimedia technology focused mainly on designing high quality audio and graphical imagery as well as providing adequate performance levels that the users demand for multimedia applications. However, the concept of multimedia has expanded into New-Media that involves variety use of multimedia data in consumer-oriented applications, such as...

  • Multithreaded virtual processor on DSM

    Creator:
    An, Ho Seok
    Abstract:
    Modern superscalar processors exploit instruction-level parallelism (ILP) by issuing multiple instructions in a single cycle because of increasing demand for higher performance in computing. However, stalls due to cache misses severely degrade the performance by disturbing the exploitation of ILP. Multiprocessors also greatly exacerbate the memory latency problem. In SMPs,...

  • Observability and information structure of nonlinear systems

    Creator:
    Hwang, Chun Sik
    Abstract:
    An observability problem for both deterministic and stochastic systems is studied here. Deterministic observability is a determination of whether every state of the system is connected to the observation mechanism and how it is connected, if connected. On the other hand, stochastic observability discusses the "tightness" of the connection in...

  • Analytical model of GaAs MESFET output conductance with frequency and temperature dependent parameters

    Creator:
    Lam, Steven C. F.
    Abstract:
    The output characteristics of a conventional GaAs depletion-mode MESFET device have been investigated. One of the important parameters of the small-signal GaAs MESFET model, g[subscript ds] (output conductance), is shown to be frequency and temperature dependent. Variations in g[subscript ds] are a serious problem in many analog and digital circuits...

  • Hot carrier degradation of sub-micron n-channel MOSFETs subject to static stress

    Creator:
    Aminzadeh, Payman G.
    Abstract:
    Hot carrier effects in sub-micron lightly doped drain (LDD) n-channel MOSFETs under static (DC) stress are studied in order to establish the degradation mechanisms of such devices. Degradation is monitored as a function of time at various gate voltages. Under accelerated aging conditions (i.e. large drain voltages) the gate voltage...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...

  • Design, fabrication, and testing of inhomogeneous dielectrics

    Creator:
    Lim, Sungkyoo
    Abstract:
    In this thesis the concept of inhomogeneous dielectrics is demonstrated for various optical coating applications. Compositionally-varying silicon oxynitride (SiON) dielectric layers, with the refractive index varying as a function of position, are grown by computer-controlled plasma-enhanced chemical vapor deposition (PECVD) using silane, nitrogen, and nitrous oxide reactant gases. Compositionally graded...
