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....

The design of a postfilter for a delta-sigma digital-to-analog converter

Creator:: Chen, Chao-Yin
Resource Type:: Masters Thesis
Full Text:: encouragement. I want to express my thanks to Professor Vijai K. Tripathi and Professor Jack Kenney for serving

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...

Sensitivity analysis and architectural comparison of narrow-band sharp-transition digital filters

Creator:: Kulkarni, Satish S.
Abstract:: Due to advances in high-density low-cost VLSI and communication technology, digital filtering and signal processing are being widely used for real-time signal processing applications. Given the filter specification, choosing the best filter structure for a given application is not a trivial task. The choice of a particular filter structure depends...

Analysis and modeling of lossy planar optical waveguides and application to silicon-based structures

Creator:: Remley, Catherine A.
Abstract:: This work is concerned with the modeling and analysis of lossy planar dielectric optical waveguides. Loss mechanisms which affect propagation characteristics are reviewed, and various representations of the propagation constant in the lossy case are defined. Waveguide structures which are susceptable to absorption and/or to leakage loss, in particular silicon-based...
Resource Type:: Masters Thesis
Full Text:: financial support for three years. I am grateful to the members of my graduate committee, Drs. Vijai K

Analysis and modeling of GaAs MESFET's for linear integrated circuit design

Creator:: Lee, Mankoo
Abstract:: A complete Gallium Arsenide Metal Semiconconductor Field Effect Transistor (GaAs MESFET) model including deep-level trap effects has been developed, which is far more accurate than previous equivalent circuit models, for high-speed applications in linear integrated circuit design. A new self-backgating GaAs MESFET model, which can simulate low frequency anomalies, is...
Resource Type:: Dissertation
Full Text:: , Dr. Vijai K. Tripathi for his generous concern throughout this research study. Thanks are also

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...

Ultra low voltage DRAM current sense amplifier with body bias techniques

Creator:: Gang, Yung-jin, 1957-
Abstract:: The major limiting factor of DRAM access time is the low transconductance of the MOSFET's which have only limited current drive capability. The bipolar junction transistor(BJT) has a collector current amplification factor, β, times base current and is limited mostly by the willingness to supply this base current. This collector...
