  • Efficient content distribution on source constraint networks: peer communication

    Creator:
    Kamath, Rohit Vinodanand
    Abstract:
    Popular applications such as P2P file sharing, multiplayer gaming, videoconferencing, etc. rely on the efficiency of content distribution from a single source to multiple receivers. Most users of these applications are on the widely prevalent source constraint networks such as the Digital Subscriber Line (DSL) and wireless networks. Overlay multicast...

  • Development test suite for FPGA TekBot learning platform

    Creator:
    Lai, Gerald
    Abstract:
    As the Tekbots program expands into senior and graduate level classes at Oregon State University, so does the need arise for more complex learning platforms. These complex hardware platforms cannot be adequately tested in a manufacturing environment as we have done previously. Also, due to their complexity, these platforms require...

  • Multimedia streaming using multiple TCP connections

    Creator:
    Tullimalli, Sunand
    Abstract:
    Packet loss, delay and time-varying bandwidth are three main problems facing multimedia streaming applications over the Internet. Existing techniques such as Media-aware network protocol, network adaptive source and channel coding, etc. have been proposed to either overcome or alleviate these drawbacks of the Internet. But these techniques either need specialized...

  • Advances in side-channel cryptanalysis : microarchitectural attacks

    Creator:
    Aciiçmez, Onur
    Abstract:
    Cryptographic devices leak timing and power consumption information that is easily measurable, radiation of various levels, and more. Such devices also have additional inputs, other than plaintext and keys, like voltage, which can be modified to force the device to produce certain faulty outputs that can be used to reveal...

  • Designing and understanding information retrieval systems using collaborative filtering in an academic library environment

    Creator:
    Jung, Seikyung
    Abstract:
    Accessing information on the Web has become ingrained into our daily lives, and we seek information from many different sources, including conference and journal publications, personal web pages, and others. Increasingly, web-based information retrieval systems such as web-based search engines, library on-line catalog systems, and subscription-based federated search systems are...

  • Low-complexity high-speed VLSI design of low-density parity-check decoders

    Creator:
    Cui, Zhiqiang
    Abstract:
    Low-Density Parity-check (LDPC) codes have attracted considerable attention due to their capacity approaching performance over AWGN channel and highly parallelizable decoding schemes. They have been considered in a variety of industry standards for the next generation communication systems. In general, LDPC codes achieve outstanding performance with large codeword lengths (e.g.,...

  • Network coding in relay networks

    Creator:
    Alban, Eduardo
    Abstract:
    Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...

  • Behavior-based mobility prediction for fast handoffs in wireless LANs

    Creator:
    Wanalertlak, Weetit
    Abstract:
    Wireless Networks have been widely adopted into a major part of today's network infrastructure. They have become a popular technology to not only expand the coverage of wired networks but also to interconnect a large wireless network, i.e., wireless mesh networks. As they allow more flexible communication than traditional wired-networks...

  • Learning cost-sensitive diagnostic policies from data

    Creator:
    Zubek, Valentina Bayer
    Abstract:
    In its simplest form, the process of diagnosis is a decision-making process in which the diagnostician performs a sequence of tests culminating in a diagnostic decision. For example, a physician might perform a series of simple measurements (body tem- perature, weight, etc.) and laboratory measurements (white blood count, CT scan,...

  • Low-power dynamic CMOS circuits in high-performance memory arrays

    Creator:
    Patwary, Md. Ataur R.
    Abstract:
    Dynamic CMOS circuits are commonly used in high-performance memory arrays to implement wide-NOR logic functions for their read and search operations. This is because dynamic circuits have significantly higher speed and lower area compared to static circuits for performing similar operations. Register File (RF) arrays are located at the top...
