  • 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...

  • A generalization of tree automata and its relation to matrix grammars

    Creator:
    Vomocil, David Leo
    Abstract:
    In this thesis we introduce alpha and beta tree acceptors, generalizations of tree automata. The alpha tree acceptors recognize a tree by final symbol and the beta tree acceptors by final state. We show that alpha and beta tree acceptors recognize the same sets of Gorn trees and demonstrate that...

  • Information Foraging Theory as a Unifying Foundation for Software Engineering Research : Connecting the Dots

    Creator:
    Piorkowski, David
    Abstract:
    Empirical studies have shown that programmers spend up to one-third of their time navigating through code during debugging. Although researchers have conducted empirical studies to understand programmers’ navigation difficulties and developed tools to address those difficulties, the resulting findings tend to be loosely connected to each other. To address this...

  • Position-Dependent Codon Usage Bias in the Human Transcriptome

    Creator:
    Subramanian, Kaavya
    Abstract:
    All life depends on the reliable translation of RNA to protein according to complex interactions between translation machinery and RNA sequence features. While ribosomal occupancy and codon frequencies vary across coding regions, well-established metrics for computing coding potential of RNA do not capture such positional dependence. Here, we investigate position-dependent...

  • Computational Approaches for RNA Structure Prediction with Dynamic Programming and Deep Neural Networks

    Creator:
    Deng, Dezhong
    Abstract:
    Our goal is to build a system to model the RNA sequences that reveals their structural information by using efficient dynamic programming algorithms and deep learning approaches. We aim to 1) achieve linear-time for RNA secondary structure prediction based on existing minimum free energy models; 2) utilize deep neural networks...

  • New Strategies to Develop Hidden Markov Models Combining KEGG and Pfam

    Creator:
    Gupta, Sonica
    Abstract:
    Profile Hidden Markov Models utilize the information stored in a multiple sequence alignment such as its residues and conserved regions to assign probabilities at each column. This indicates areas in the sequences where similar functionality is observed. These probability weights are then combined to assign a sequence score, which is...

  • Determining free energies of hard sphere fluids via Monte Carlo simulation

    Creator:
    Valeskea, Austin
    Abstract:
    Free energy is a fundamental property of a thermodynamic system, from which pressure, entropy, and other interesting properties can be derived. It is useful, then, to be able to accurately compute the free energy at various densities and temperatures in a way that can serve as the basis for further...

  • An enhanced version of Caesar supporting 45° geometries

    Creator:
    Lanfri, Ann R.
    Abstract:
    Caesar is an interactive graphic editor that is used to generate layouts for VLSI circuits. It runs on a VAX-11 /780 under the UNIX operating system with Berkeley extensions. Caesar has a unique and simple user interface. Phled is an enhanced version of Caesar that runs on a M68000-based engineering...

  • Tracing the Pacific Islander Diaspora in the Pacific Northwest

    Creator:
    Yarbrough, Nicole
    Abstract:
    The Pacific Islander diaspora in the Pacific Northwest United States is a unique community characterized by diverse cultures, experiences, and motivations for migration. This study aimed to explore the narratives of individuals from different Pacific Islander backgrounds residing in Oregon, shedding light on their reasons for migration and the impact...

  • Automatic Classification of Ultrasonic Harbor Porpoise Clicks in a Varying Noise Environment

    Creator:
    De Leon, Daniel
    Abstract:
    This study compares three approaches in the design of an autonomous machine listening agent that predicts harbor porpoise ultrasonic echolocation clicks in diverse noise environments. Considering the temporal variations of noisy coastal ocean soundscapes which the harbor porpoises inhabit, we propose a leave-one-day-out (LODO) cross-validation strategy in the training of...
