  • Power Electric System Load and Generation Forecasting via ARMA, ARIMA, and K-Medoids Methods for Grid Expansion Purposes: A Comparison

    Creator:
    McLaughlin, Zachery D.
    Abstract:
    The electric power grids of countries across the globe rely on load and generation forecasting to know when, where, and how much resources need to be dispatched to sustain proper grid operation. Because of this, forecasting needs to be highly accurate to avoid unnecessary resource dispatch which can be costly....

    Creator:
    Arnett, David W.
    Abstract:
    A method and apparatus are presented for generating suppressed carrier digital clock signals. These clock signals have the advantage of being broad band in nature and thus exhibiting lower power spectral density. Structures or systems utilizing such clock signals would be less likely to create electromagnetic noise of sufficient intensity...

  • Rapid hardware implementations of classical modular multiplication

    Creator:
    Johnson, Scott Andrew
    Abstract:
    Modular multiplication is a mathematical operation fundamental to the RSA cryptosystern, a public-key cryptosystem with many applications in privacy, security, and authenticity. However, cryptosecurity requires that the numbers involved be extremely large, typically ranging from 512-1024 bits in length. Calculations on numbers of this magnitude are cumbersome and lengthy; this...

  • Methodology for evaluating mechanical power in small-scale WEC experiments

    Creator:
    Simmons, Asher
    Abstract:
    Wave energy converters (WECs) are a broad class of emerging technology that converts hydrokinetic energy into some other useful form, such as electricity. The last stage in this transformation, the power take-off (PTO) subsystem, is often not experimentally evaluated until half-way through the recommended development process. This delay in evaluation...
