  • Design considerations for fast-settling operational amplifiers

    Creator:
    Yang, Howard C.
    Abstract:
    The design considerations for fast-settling operational amplifiers (opamps) differ significantly between sampled-data switchedcapacitor (SC) and conventional continuous-time applications. In SC circuits, the shape of the output voltage waveform of an opamp is of no consequence provided that the output settles to within a specified tolerance of its steady-state value prior...

  • Target-based coverage extension of 802.11 MANETs via constrained UAV mobility

    Creator:
    Johnson, Taylor N.
    Abstract:
    MANETs are known to be useful in situations where mobile nodes need to communicate and coordinate in dynamic environments with no access to fixed network infrastructure. However, connectivity problems can occur when sub-groups within a MANET move out of communication range from one another. The increasingly prolific use of UAVs...

  • Dynamic and Dual Streaming Methods for H.264 Video and Parallel Performance Modeling

    Creator:
    Johnson, Taylor N.
    Abstract:
    Traditional approaches to streaming H.264 video over a network typically rely on a single method of transport (i.e., reliable or unreliable) and/or use static values for parameters that can have a significant negative impact on the perceptual quality of the received video. This dissertation presents a dynamic method for wireless...

  • Design and computer-aided optimization of RF CMOS power amplifiers

    Creator:
    Gupta, Ravi
    Abstract:
    In recent years, there has been an extensive effort to develop low-cost implementations of radio frequency integrated circuits for consumer applications. This thesis is a research effort in the design and implementation of integrated RF CMOS Power Amplifiers (PAs). A significant challenge in the implementation of RF CMOS ICs is...

  • Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

    Creator:
    Gatimu, Kevin
    Abstract:
    The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

  • Detection and diagnosis of parameters change in linear system using time-frequency transformation

    Creator:
    Park, Dae-hyun
    Abstract:
    A systematic optimization of the Cohen class time-frequency transformation for detecting the parameters change is developed. The local moments approach to change detection is proposed and a general formula for the local moments is derived. The optimal kernel functions of the time-frequency transformation are determined based on the combined criteria...

  • Stabilizing control strategies for the doubly-excited machine

    Creator:
    Permantier, Gerald A.
    Abstract:
    Mathematical models for the doubly-fed machine are presented. The properties of the machine with rotor excitation as supplied by a power converter with voltage source character are reviewed. The peculiar torque-speed characteristic of the machine in this operating mode and its effect on the stability of the machine are presented....

  • A Fully Integrated Bio-potential Low-noise Amplifier Utilizing Capacitor Multipliers

    Creator:
    Yong, OnnLim
    Abstract:
    In any biomedical signal acquisition system, a front-end amplifier is needed to amplify low amplitude bio-signals while filtering out any unwanted low-frequency artifacts. The design of low frequency poles within the sub-Hz range implies very large time-constants which goes against system integrability. In recent years, the pseudo resistor has been...

  • Adaptive model-based motion estimation

    Creator:
    Crinon, Regis
    Abstract:
    A general discrete-time, adaptive, multidimensional framework is introduced for estimating the motion of one or several object features from their successive non-linear projections on an image plane. The motion model consists of a set of linear difference equations with parameters estimated recursively from a non-linear observation equation. The model dimensionality...

  • Optimal control of an induction motor

    Creator:
    Yarimbiyik, Bulent
    Abstract:
    With the development of converters and inverters, it became possible to control the stator current of an induction motor. The differential equations which describe transient behavior of the induction motor are conveniently expressed by transforming the stator and rotor variables to d-q axes rotating at synchronous speed. The transient behavior...
