  • Nielson, Kayleigh (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological SciencesArts and ScienceDepartment of Biological Sciences, 2017)
    This thesis investigates the factors that affect non-native plant occurrence at freshwater springs in southern Alberta, Canada, with special focus on the effect of human disturbance, and the life history traits of ...
  • Fuller, Brandon (Lethbridge, Alta. : University of Lethbridge, Dept. of Mathematics and Computer SciencesArts and ScienceDepartment of Mathematics and Computer Science, 2018)
    Given a group G, any subset C of G\{e} induces a Cayley graph, Cay(G,C). The set C also induces a natural edge-colouring of this graph. All affine automorphisms of the Cayley graph preserve this edge-colouring. A Cayley ...
  • Pelletier, Amanda (Lethbridge, Alta. : University of Lethbridge, Dept. of PsychologyArts and SciencePsychology, 2017)
    Current research is not unanimous on whether object play is motivationally linked to foraging, due to a lack of systematic comparison of the behavioural structure of both activities. This thesis aimed to address this gap ...

    Locating objects in space is typically thought of as a visual task. However, not everyone has access to visual information, such as the blind. The purpose of this thesis was to investigate whether it was possible to convert ...
  • Nayeem, Mir Tafseer; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of Mathematics and Computer ScienceArts and ScienceDepartment of Mathematics and Computer Science, 2017)
    In this thesis, we have developed several techniques for tackling both the extractive and abstractive text summarization tasks. We implement a rank based extractive sentence selection algorithm. For ensuring a pure sentence ...
  • Stark, Rachel A.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of NeuroscienceArts and ScienceDepartment of Neuroscience, 2017)
    Rodent ultrasonic vocalizations (USVs) have been recorded throughout the lifespan of rats. The major finding is that USVs in infants and adults are different. It is hypothesized that there should be a transition in vocal ...
  • Purohit, Parijat Prashun; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of Mathematics and Computer ScienceArts and ScienceDepartment of Mathematics and Computer Science, 2017)
    Given a function promised to be constant or balanced. Deutsch's algorithm and it's extension Deutsch-Jozsa are the algorithms that can determine the property of the function in constant number of queries. The algorithm ...
  • Bosso, Pasquale; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of Physics and AstronomyArts and ScienceDepartment of Physics and Astronomy, 2017)
    The fundamental physical description of Nature is based on two mutually incompatible theories: Quantum Mechanics and General Relativity. Their unification in a theory of Quantum Gravity (QG) remains one of the main challenges ...

    Research has demonstrated an interaction between speech processes and manual actions. The wide variety of methods and theories used to investigate the interaction produced contradictions and raised many questions. The ...
  • Burke, Candace J.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of NeuroscienceArts and ScienceDepartment of Neuroscience, 2017)
    This thesis explores how rats use various categories of ultrasonic vocalizations in social contexts. In the first study male juvenile rats were socially isolated and trained to anticipate play with a conspecific. During ...
  • Xu, Linglin; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of GeographyArts and ScienceDepartment of Geography, 2017)
    With a growing population and a rising standard of living, how to maintain food production that meets the increasing demand for food without compromising the ability of future generations to meet their own needs is becoming ...
  • Akter, Sharmin; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of Mathematics and Computer ScienceArts and ScienceDepartment of Mathematics and Computer Science, 2017)
    We examine the problem of covering points with minimum number of axis-parallel lines in three dimensional space which is an NP-complete problem. We introduce Lagrangian based algorithms to approximate the point cover ...

    Machine learning techniques have been applied to improve the learning process and to learn about the utilization of natural languages. Previous research has shown that similar techniques can be applied in the analysis ...
  • Jensen, Ashley Marie; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of Biological SciencesArts and ScienceDepartment of Biological Sciences, 2017)
    This study was the first to examine the genetic structure of a widespread game bird, the Ruffed Grouse (Bonasa umbellus). We uncovered multiple factors acting in concert that are likely responsible for mediating contemporary ...
  • Ansari, Lazima; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : Universtiy of Lethbridge, Department of Mathematics and Computer ScienceArts and ScienceDepartment of Mathematics and Computer Science, 2017)
    Large-scale optimization of combinatorial problems is one of the most challenging areas. These problems are characterized by large sets of data (variables and constraints). In this thesis, we study large-scale optimization ...
