  • 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...

  • A simple RLS-POCS solution for reduced complexity ADSL impulse shortening

    Creator:
    Helms, Sheldon J.
    Abstract:
    Recently, with the realization of the World Wide Web, the tremendous need for high-speed data communications has grown. Several access techniques have been proposed which utilize the existing copper twisted pair cabling. Of these, the xDSL family, particularly ADSL and VDSL, have shown great promise in providing broadband or near-broadband...

  • Content-based color image retrieval

    Creator:
    Varanguien de Villepin, Audrey
    Abstract:
    A fully automated method for content-based color image retrieval is developed to extract color and shape content of an image. A color segmentation algorithm based on the k-mean clustering algorithm is used and a saturated distance is proposed to discriminate between two color points in the HSV color space. The...

  • Efficient use of time information in analog-to-digital converters

    Creator:
    Hu, Yue
    Abstract:
    Time-domain data conversion has recently drawn increased research attention for its highly digital nature in favor of process technology scaling. Also, as the time information being carried by binary voltage, time-domain operation is much less sensitive to voltage noise compared to conventional voltage domain operation. However, for analog-to-digital converter (ADC)...

  • A schemata model of real-time information processing systems

    Creator:
    Szulewski, Paul A.
    Abstract:
    In an attempt to provide a practical means to measure the information processing capacity of a real-time digital processing system a theoretical framework, the Real-Time Schemata, whose basis is a schematic description and a measure of "useful information," is presented. The description applies to processes that would typically be implemented...

  • Design and Implementation of a Wearable Walking Navigation Assistance System for the Vision Impaired

    Creator:
    Sylwester, Sean T.
    Abstract:
    Few navigation-assistance technologies for vision impaired individuals are practical due to inhibiting factors such as cost, comfort, convenience, and overall usefulness of the assistance. This thesis will present the design and implementation of a navigation assistance system intended to address these concerns. The presented system improves on existing technologies by...

  • Information processing errors in linear feedback control systems

    Creator:
    Chong, Hoi-yeung
    Abstract:
    This report is concerned with the analysis of the effect of finite wordlength, channel capacity and source rate in digital feedback control of linear systems. The cases considered are (1) finite wordlength A/D conversion, no feedback delay, ideal ROM (read only memory) controller; (2) finite A/D wordlength (source rate), state...

  • Efficient decoder design for error correction codes

    Creator:
    He, Jinjin
    Abstract:
    Error correction codes (ECCs) have been widely used in communication systems and storage devices. Nowadays, the rapid development of integrated circuit technologies makes feasible the implementation of powerful ECCs such as turbo code and low-density parity-check (LDPC) code. However, these high-performance codes require complex decoding algorithms, resulting in large hardware...

  • A probabilistic framework and algorithms for modeling and analyzing multi-instance data

    Creator:
    Behmardi, Behrouz
    Abstract:
    Multi-instance data, in which each object (e.g., a document) is a collection of instances (e.g., word), are widespread in machine learning, signal processing, computer vision, bioinformatic, music, and social sciences. Existing probabilistic models, e.g., latent Dirichlet allocation (LDA), probabilistic latent semantic indexing (pLSI), and discrete component analysis (DCA), have been...
