  • A comparison of single runs versus multistart for simulated annealing and threshold accepting

    Creator:
    Crews, Matthew
    Abstract:
    Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...

  • Bayesian optimization with empirical constraints

    Creator:
    Azimi, Javad
    Abstract:
    Bayesian Optimization (BO) methods are often used to optimize an unknown function f(•) that is costly to evaluate. They typically work in an iterative manner. In each iteration, given a set of observation points, BO algorithms select k ≥ 1 points to be evaluated. The results of those points are...

  • Modeling of Power Efficiency in a Magnetohydrodynamic Generator

    Creator:
    Redle, Michael T.
    Abstract:
    The introduction of an Magnetohydrodynamic (MHD) generator in coal or natural gas energy plants could significantly increase the efficiency by converting kinetic and thermal energy of the combustion exhaust to electrical energy by the generation of a Faraday and Hall current. The traditional MHD system was transformed into a simplified...

  • A Simple Leapfrog Integration Scheme to Find Optimal Interplanetary Trajectories

    Creator:
    Kelley, Scott M.
    Abstract:
    The calculation of interplanetary trajectories is a numeric problem which requires a high degree of precision for the results to be accurate. A computer program was written for this project which uses leapfrog integration combined with Newton’s method of iterative root finding to find ideal interplanetary trajectories. Reasonable initial conditions...

  • Optimal harvesting of continuous age structured populations

    Creator:
    Smith, Steven J.
    Abstract:
    We investigate the optimal harvesting strategies for McKendrick type population models. Models of this type endow the population with a continuous age structure. They consist of a partial differential equation with a boundary condition which involves an integral of the solution. We study two problems, the first concerns the yield...

    Creator:
    Chambers, Christopher and Scaffidi, Christopher
    Abstract:
    This paper proposes a technique, called Smell-driven performance tuning (SDPT), which semi-automatically assists end-user programmers with fixing performance problems in visual dataflow programming languages. A within-subjects laboratory experiment showed SDPT increased end-user programmers’ success rate and decreased the time they required. Another study, based on using SDPT to analyze a...

  • Describing function theory as applied to thermal and neutronic problems

    Creator:
    Nassersharif, Bahram
    Abstract:
    Describing functions have traditionally been used to obtain the solutions of systems of ordinary differential equations. In this work the describing function concept has been extended to include nonlinear, distributed parameter partial differential equations. A three-stage solution algorithm is presented which can be applied to any nonlinear partial differential equation....

  • ECDSA optimizations on an ARM processor for a NIST curve over GF(p)

    Creator:
    Tanik, Haluk Kent
    Abstract:
    The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analog of the Digital Signature Algorithm (DSA) and a federal government approved digital signature method. In this thesis work, software optimization techniques were applied to speed up the ECDSA for a particular NTST curve over GF(p). The Montgomery multiplication...

  • Machine learning in engineering : techniques to speed up numerical optimization

    Creator:
    Cerbone, G. (Giuseppe)
    Abstract:
    Many important application problems in engineering can be formalized as nonlinear optimization tasks. However, numerical methods for solving such problems are brittle and do not scale well. For example, these methods depend critically on choosing a good starting point from which to perform the optimization search. In high-dimensional spaces, numerical...

  • ECDSA optimizations on ARM processor for a NIST curve over GF(2m)

    Creator:

    Abstract:
    The Elliptic Curve Digital Signature Algorithm (ECDSA) is one of the most popular algorithms to digitally sign streams or blocks of data. In this thesis we concentrate on porting and optimizing the ECDSA on the ARM7 processor for a particular NIST curve over GF(2[superscript m]). The selected curve is a...
