The Faculty of Science represents one of the strongest academic areas at the University of Regina. It attracts more than half of all external research funding and holds two Canada Research Chairs. With the need for scientific and technical skills in the 21st century, students will find that the strengths of the Faculty make it an attractive one in which to further their education.
The Faculty is composed of six departments:

A Study of Visually Linked Keywords to Support Exploratory Browsing in Academic Search
(Journal of the Association for Information Science and Technology, 2022)While the search interfaces used by common academic digital libraries pro vide easy access to a wealth of peerreviewed literature, their interfaces pro vide little support for exploratory browsing. When faced with a ... 
A survey of semisimple algebras in algebraic combinatorics
(Springer Nature, 20211021)This is a survey of semisimple algebras of current interest in algebraic combinatorics, with a focus on questions which we feel will be new and interesting to experts in group algebras, integral representation theory, and ... 
The Effects of Simulated Interruptions on Mobile Search Tasks
(Journal of the Association for Information Science and Technology, 202110)it is clear that using a mobile device can interrupt realworld activities such as walking or driving, the effects of interruptions on mobile device use have been understudied. We are particularly interested in how the ... 
Corrigendum to “The recognition problem for table algebras and realitybased algebras” [J. Algebra 479 (2017) 173–191]
(2019)This note reports and corrects an error in the above article. 
Orders of Torsion Units of integral realitybased algebras with rational multiplicities
(2018)A realitybased algebra (RBA) is a finitedimensional associative algebra with involution over C whose distinguished basis B contains 1 and is closed under pseudoinverse. An integral RBA is one whose structure constants ... 
Engaging Indigenous Youth in Science with the HighAltitude Balloon Experiment
(Scientific Research Publishing, 20190220)Our custom highaltitude balloon experiment kit with the complete set of instructions has been successfully used to engage high school and postsecondary students across Canada. This article describes how the highaltitude ... 
Incorporation of HighAltitude Balloon Experiment in High School Science Classrooms
(Scientific Research Publishing, 20190214)We have been launching highaltitude balloons to engage students in science since 2013. Our custom balloon kit allows high school teachers and students to collect environmental data and capture videos. Through our ... 
Winter climate affects torpor patterns and roost choice in New Zealand lesser shorttailed bats
(WileyBlackwell (Zoological Society of London), 2017)Variation in winter conditions differentially impacts thermoregulation of endotherms, with some species using torpor as an energysaving strategy during periods of negative energy balance. We evaluated how differences ... 
Quantifying Relative Levels of Solar Radiation at Bat Roosts Using Pyranometers
(Wiley  The Wildlife Society, 2017)Although the amount of solar radiation received at roost sites used by bats has been speculated to be a factor driving roostsite selection and roost switching behavior, few studies have scientifically quantified and ... 
Stressful summers? Torpor expression differs between high and lowlatitude populations of bats
(American Society of Mammalogists, 2017)Variation in weather and food availability impacts the energy budgets of endotherms, with some species using torpor as an energysaving strategy during periods of negative energy balance. We evaluated how latitudinal differences ... 
Home is where you hang your bat: winter roost selection by prairieliving big brown bats
(American Society of Mammalogists, 2017)Information on the roost requirements of small, temperatezone hibernating bats, which can spend up to 8 months in hibernation, is crucial to their conservation. We studied male big brown bats (Eptesicus fuscus) in ... 
Thermoregulation by captive and freeranging Egyptian rousette bats (Rousettus aegyptiacus) in South Africa
(American Society of Mammalogists, 2017)Many bats, including some smallbodied tropical and subtropical Pteropodidae, use torpor to offset energetic constraints. We tested the hypothesis that mediumsized (110–160 g) caveroosting Egyptian rousette bats (Rousettus ... 
Hung out to dry? Intraspecific variation in water loss in a hibernating bat
(Springer, 2017)Hibernation is a period of water deficit for some small mammals, and humidity strongly influences hibernation patterns. Dry conditions reduce length of torpor bouts, stimulate arousals, and decrease overwinter survival. ... 
Cold and alone? Roost choice and season affect torpor patterns in lesser short‑tailed bats
(Springer, 2017)Seasonal changes in weather and food availability differentially impact energy budgets of small mammals such as bats. While most thermal physiological research has focused on species that experience extreme seasonal ... 
Approximation and Visualization of Sets Defined by Iterated Function Systems
(University of Regina, 199103)An iterated function system (IFS) is defined to be a set of contractive affine transformations. When iterated, these transformations define a closed set, called the attractor of an IFS, which has fractal characteristics. ... 
The Escape Buffer: Efficient Computation of Escape Time for Linear Fractals
(Canadian Human Computer Communications Society, 19950517)The study of linear fractals has gained a great deal from the study of quadratic fractals, despite important differences. Methods for classifying points in the complement of a fractal shape were originally developed for ... 
Rendering Methods for Iterated Function Systems
(NorthHolland, 199112)This paper describes rendering methods for iterated function systems (IFS’s). The rendering process consists of the generation of a field of data using an IFS and its visualization by means of computer graphics. Two groups ... 
A Linear Model for ThreeWay Analysis of Facial Similarity
(Springer, Cham, 20180518)Card sorting was used to gather information about facial similarity judgments. A group of raters put a set of facial photos into an unrestricted number of different piles according to each rater’s judgment of similarity. ... 
An ErdősKoRado theorem for the derangement graph of \(PGL_3(q)\) acting on the projective plane
(SIAM J. Discrete Math. 28, 2014)In this paper we prove an ErdősKoRadotype theorem for intersecting sets of permutations. We show that an intersecting set of maximal size in the projective general linear group \(PGL_3(q)\), in its natural ... 
An ErdősKoRado theorem for finite \(2\)transitive groups
(European Journal of Combinatorics, 2016)We prove an analogue of the classical ErdősKoRado theorem for intersecting sets of permutations in finite \(2\)transitive groups. Given a finite group \(G\) acting faithfully and \(2\)transitively on the set ...
