    This thesis is mainly concerned with the orthogonal designs of Baumert-Hall array type, OD(4n;n,n,n,n) where n=2k, k is odd integer. For every odd prime power p^r, we construct an infinite class of amicable T-matrices ...
  • Gholamiangonabadi, Hamed (Lethbridge, Alta. : University of Lethbridge, Dept. of Mathematics and Computer Science, c2012Arts and ScienceDepartment of Mathematics and Computer Science, 2012)
    Our main aim in this thesis is to produce new T-matrices from the set of existing T-matrices. In Theorem 4.3 a multiplication method is introduced to generate new T-matrices of order st, provided that there are some ...
  • Appau, Adriana Boakyewaa; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Economics, c2013Arts and ScienceDepartment of Economics, 2013)
    This thesis employs a dynamic form of the gravity model and data from 1988-2005 to estimate the effects of RTAs in SSA on intra-African trade. The thesis proposes a better approach to examining member-nonmember trade ...
  • Chipindirwi, Simbarashe (Lethbridge, Alta. : University of Lethbridge, Dept. of Chemistry and Biochemistry, c2012Arts and ScienceDepartment of Chemistry and Biochemistry, 2012)
    Gene expression is random owing to the low copy numbers of molecules in a living cell and the best way to study it is by use of a stochastic method, specifically the chemical master equation. The method is used here to ...
  • Rahman, Tanzila; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2013Arts and ScienceDepartment of Biological Sciences, 2013)
    Most cancer treatments are genotoxic agents that target and damage DNA as part of their mechanism of action. Recently, it was discovered that cancer cells with damaged DNA can escape the DNA damage checkpoint and enter ...
  • Xia, Qing; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta : University of Lethbridge, Dept. of Biological SciencesArts and ScienceDepartment of Biological Sciences, 2017)
    The biogeography of herbivorous insects often depends on climate and host plants. Potato psyllid, Bactericera cockerelli (Sulc), is an insect that presents a threat to the western Canadian potato industry. It is native to ...
  • Watson, Stephnie; University of Lethbridge. Faculty of Arts and Science (Department of Geography, 2018)
    I completed two research projects for this thesis. The first research project examined fuel efficiency and vehicle emission differences between Lethbridge Transit’s hybrid and diesel buses. The second research project ...
  • Hambrook, Dillon A.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience, 2013Arts and ScienceDepartment of Neuroscience, 2013)
    It is usually easy to understand speech, but when several people are talking at once it becomes difficult. The brain must select one speech stream and ignore distracting streams. This thesis tested a theory about the neural ...
  • Gonzalez, Claudia L. R.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2004Arts and ScienceDepartment of Neuroscience, 2004)
    This thesis investigates the behavioural and anatomical correlates of recovery from motor cortex damage in rats. The effectiveness of behavioural, pharmacological, and regenerative treatments was investigated using models ...
  • Charlton, Christopher; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Political Science, 2009Arts and ScienceDepartment of Political Science, 2009)
    Like its counterparts in other provinces, the Alberta New Democratic Party has a formal relationship with organized labour. This thesis will examine the logic of the underlying relationship that persists between the two ...
  • Hosseini, Seyed Hossein; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta : University of Lethbridge, Dept. of Chemistry and BiochemistryArts and ScienceDepartment of Chemistry and Biochemistry, 2016)
    The spatio-temporal organization of one RNA polymerase (RNAP) along a DNA strand is explored by studying a kinetic stochastic model for transcription process, the first step in gene expression. An explicit expression for ...
  • Shahmansouri, Houman; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta : University of Lethbridge, Dept. of Mathematics and Computer ScienceArts and ScienceDepartment of Mathematics and Computer Science, 2016)
    In the computer age, managing large data repositories is one of the common challenges, especially for music data. Categorizing, manipulating, and refining music tracks are among the most complex tasks in Music Information ...

    Music classification is a core task in the field of Music Information Retrieval (MIR). Classification refers to recognizing patterns in data. Music classification assigns genre, style, mood and etc. to each piece of ...
  • Comeau, Wendy L.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of NeuroscienceArts and ScienceDepartment of Neuroscience, 2007)
    The effects of experience on developing and mature prefrontal brain circuitry and behaviour were investigated in rats using Ritalin, complex housing, and learning as tools. The results showed that Ritalin altered prefrontal ...
  • Richards, Sonja (Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience, 2011Arts and ScienceDepartment of Neuroscience, 2011)
    This thesis examines both behavioral and anatomical effects of prenatal exposure of Valproic Acid (VPA) on Long Evans rats. Tactile stimulation (TS) is then used to investigate its’ effect on remediating any abnormalities ...
