  • Gergel, Barry; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2007Faculty of Arts and ScienceDepartment of Mathematics and Computer Science, 2007)
    A new automatic compression scheme that adapts to any image set is presented in this thesis. The proposed scheme requires no a priori knowledge on the properties of the image set. This scheme is obtained using a unified ...
  • Ali, Husam Deeb Abdullah Deeb (Lethbridge, Alta. : University of Lethbridge, Dept. of Mathematics and Computer Science, c2012Arts and ScienceDepartment of Mathematics and Computer Science, 2012)
    Humans are not often very skilled in asking good questions because of their inconsistent mind in certain situations. Thus, Question Generation (QG) and Question Answering (QA) became the two major challenges for the Natural ...
  • Kennedy, Peter (Lethbridge, Alta. : University of Lethbridge, Dept. of GeographyArts and ScienceDepartment of Geography, 2014)
    Spectral features within satellite images change so frequently and unpredictably that spectral definitions of land cover are often only accurate for a single image. Consequently, land-cover maps are expensive, because the ...
  • Mlynarski, Angela; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Arts and ScienceDepartment of Mathematics and Computer Science, 2006)
    A digital library is a collection of services and information objects for storing, accessing, and retrieving digital objects. Automatic text summarization presents salient information in a condensed form suitable for user ...
  • Kolla, Maheedhar; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2004Arts and ScienceDepartment of Mathematics and Computer Science, 2004)
    Summarization is a complex task that requires understanding of the document content to determine the importance of the text. Lexical cohesion is a method to identify connected portions of the text based on the relations ...
  • Waite, Wendy Lou; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2003Arts and ScienceDepartment of Neuroscience, 2003)
    This thesis examined the role of exogenous basic fibroblast growth factor (FGF-2) in stimulating recovery after early cortical injury. Rats with medial prefrontal cortex (MFC), posterior parietal cortex (PPC), or sham ...
  • Monfils, Marie-H.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Department of Psychology and Neuroscience, 2005Arts and ScienceDepartment of Neuroscience, 2005)
    Basic fibroblast growth factor (FGF-2) is a trophic molecule involved in a number of functions within the central nervous system (CNS), including a prominent role in the regulation of CNS responses to injury. Prior studies ...
  • Rowntree, Sharon R.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1995Arts and ScienceDepartment of Psychology, 1995)
    Basic fibroblast growth factor (bFGF) has been implicated in the brain's trophic response to injury. This thesis examined the effects of endogenous bFGF on brain plasticity and recovery of behavioral function following ...
  • Hardy, Jared C.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2007Arts and ScienceDepartment of Neuroscience, 2007)
    Conventional cylinder test measures have limited sensitivity in determining hemiparkinson rat forelimb use asymmetry and approximating substantia nigra (SN) dopaminergic neuron loss. This thesis investigates which cylinder ...
  • Shirakashi, Sho; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1999Arts and ScienceDepartment of Biological Sciences, 1999)
    A wide variety of parasites are known to cause changes in host behaviour. The altered behaviours range from simple changes in features such as activity and phototaxis, to the creation of behaviours that are new, and often ...
  • Spanswick, Simon; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2005Arts and ScienceDepartment of Neuroscience, 2005)
    Different events usually contain similar elements that can contribute to interference during memory encoding and retrieval. The hippocampus (HPC), a structure that is critically involved in some forms of memory, has been ...
  • O'Brien, Jamus; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology & NeuroscienceArts and ScienceDepartment of Neuroscience, 2007)
    In an attempt to test the hypothesis that rat's can perform very similar behaviours to episodic memory in humans, we here develop a novel Paviovian conditioning procedure demonstrating integrated what- where-when ...
  • Krimmer, Alison; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2008Arts and ScienceBiological Sciences, 2008)
    As anthropogenic demands on water resources intensify instream flow needs are becoming an increasingly important area of study, particularly over winter months during which time little is known about the behaviour and ...
  • Gerrard, Brietta; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience, 2013Arts and ScienceDepartment of Neuroscience, 2013)
    Experimental autoimmune encephalomyelitis (EAE) is an inflammatory disease of the central nervous system induced in laboratory rodents to mimic human demyelinating diseases such as multiple sclerosis (MS). This thesis ...
  • Erickson, Zachary T. (Lethbridge, Alta. : University of Lethbridge, Dept. of NeuroscienceArts and ScienceDepartment of Neuroscience, 2014)
    This thesis examines the effects of both ancestral stress and postnatal environment on behaviour in male Long Evans rats. We investigated the consequences of maternal exposure to prenatal stress across generations ...
  • Waldorf, Ryan (Lethbridge, Alta. : University of Lethbridge, Faculty of Health SciencesHealth Sciences, 2015)
    The purpose of this grounded theory study was to understand how male caregivers of spouses with dementia in rural southern and central Alberta perceive their role as a caregiver. Informed by the theoretical framework of ...

    The Fincastle Bison Kill Site (DlOx-5), located approximately 100 km east of Lethbridge, Alberta, has been radiocarbon dated to 2 500 BP. Excavations at the site yielded an extensive assemblage of lithics and faunal remains, ...
  • Varsakis, Irene; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Faculty of Arts and ScienceDepartment of Geography, 2006)
    An assemblage of distinctive projectile points from the Fincastle site (DlOx-5), Alberta at c. 2500 B.P. instigated an analysis of archaeological cultures on the Northern Plains during the late Middle Prehistoric Period. ...
