  • A force control algorithm for a wave energy linear test bed

    Creator:
    Henshaw, Nathan R.
    Abstract:
    Researchers at Oregon State University, focusing on the development of ocean wave energy converters, have designed and installed a unique linear test bed to aid in the characterization of these converters. Under the original control scheme, the linear test bed follows a position profile and is limited in its ability...

  • A high power emulation of a wind farm

    Creator:
    Lalla, Chelsea
    Abstract:
    As more wind farms are connected to the grid, the variable nature of wind energy begins to influence grid stability. Energy storage could help smooth the variable nature of wind energy. Laboratory demonstration and exploration of the interaction between different energy storage devices and wind energy could help improve and...

  • A novel method for zinc oxide nanowire sensor fabrication

    Creator:
    Pelatt, Brian D.
    Abstract:
    Interest in nanomaterials is motivated partly by their potential for sensor arrays to detect different gases. Nanowires in particular are of interest because their high surface-to-volume ratio promises the possibility of high sensitivity. However, because of their discrete quasi-one-dimensional geometry, electrical integration of nanowires into photolithographically defined devices and circuits...

  • A self-calibrated, reconfigurable RF LNA

    Creator:
    Jayaraman, Karthik
    Abstract:
    Modern wireless System-on-Chips (SoCs), such as mobile handsets, sensor networks, and mm-wave systems, integrate an entire RF system on a single CMOS chip. Such highly complex systems require significant on-chip digital signal processing to help improve the performance of highly sensitive analog/RF components. The IC market being competitive, the ability...

  • Analysis and optimal sizing of an energy storage system for wind farm applications

    Creator:
    Yen, Zuan Z.
    Abstract:
    Modern wind energy is the technology of choice with a short payback period for increasing renewable energy portfolios. Bonneville Power Administration (BPA), a United States power authority in the Pacific Northwest expects to increase their wind energy capacity from 2,000 megawatts to 6,000 megawatts within the next five years. Currently...

  • Application of WiMAX to aviation communications

    Creator:
    Kim, Sang Jun
    Abstract:
    The US military is evaluating the capabilities of emerging technologies based on IEEE 802.16 standard as a potential commercial off-the-shelf solution to support the communication requirements of the future war. In the last few years, development in military and telecommunication industries have focused on an intensive use of broadband systems,...

  • Design techniques for high efficiency LED drivers

    Creator:
    Bang, Sarvesh Jagdish
    Abstract:
    The increasing popularity of cellular phones with integrated cameras in the recent past has led to major improvements in its image quality. However, integration of new features, such as mobile email, video streaming, MP3 etc. tend to put the limitation on image quality as camera phone designers struggle to manage...

  • Development of biomimetic control strategies for the optimal use of renewable sources and energy storage systems

    Creator:
    Hapke, Hannes Max
    Abstract:
    In the year 2007, the worldwide energy consumption accumulated to a total of 16.5 billion MWh. While the resources of conventional energy production cause environmental damage, renewable energy sources like solar or wind power offer a solution to substitute for coal or nuclear generated power. Countries like Denmark and Spain...

  • Electrically tunable thin-film inductors based on synthetic antiferromagnet cores

    Creator:
    An, Na
    Abstract:
    The objective of this research is to demonstrate the feasibility of implementing electrically tunable on-chip inductors based on synthetic antiferromagnet (SAF) cores. This thin film magnetic core is made of a magnetic bi-layer antiferromagnetically coupled through a nonmagnetic spacer layer. An energy model is developed to investigate the magnetic behavior...

  • Magnetic bead detection with ferromagnetic resonance for use in immuno-biosensor application

    Creator:
    Ghionea, Simon
    Abstract:
    The objective of this thesis is to introduce and demonstrate a novel magnetic bead detector based on inductive detection at the ferromagnetic resonance (FMR) frequency for use in bio-sensing applications. Detection ability is demonstrated through theoretical arguments, numerical computer simulations, and experimental characterization of micro-fabricated detectors. The detector is composed...
