On the algebraic connectivity of graphs
(2022-04-29)Algebraic connectivity, or the second smallest eigenvalue of the Laplacian matrix, is a well-studied parameter in spectral graph theory. In this thesis, we present new upper bounds and asymptotic estimates for the algebraic ... -
ON THE APPLICATION AND COMPARISON OF CONDITION-BASED MAINTENANCE PROGNOSTICS APPROACHES: LOGICAL ANALYSIS OF DATA, ARTIFICIAL NEURAL NETWORKS, AND PROPORTIONAL HAZARDS MODELS
(2016-08-29)Condition-based maintenance (CBM) is becoming increasingly important because it performs more efficient diagnoses and prognoses based on equipment condition compared to time-based methods. CBM models greatly inform maintenance ... -
On the combinatorics of resolutions of monomial ideals
(2015)In this thesis, we investigate the relation between invariants of minimal free resolutions of monomial ideals and combinatorial properties of simplicial complexes. We provide a sufficient combinatorial condition for monomial ... -
On the Degree Polynomial of Graphs
(2023-07-28)Graph polynomials encode graph theoretic information in the form of polynomials. These polynomials have been of interest for decades, for both graph theoretic insight and their mathematical properties. This thesis discusses ... -
On the development and evolution of cartilage within non-chordate metazoa.
(Dalhousie University, 2004) -
ON THE DEVELOPMENT OF SMALL FORM FACTOR HISTOTRIPSY DEVICES FOR NEUROSURGICAL APPLICATIONS AND SMALL ANIMAL EXPERIMENTS
(2022-05-12)The development of surgical instruments is a growing area where histotripsy is relatively under represented. This work focuses on the miniaturization of histotripsy devices for introduction into the neurosurgery, cardiac, ... -
ON THE DYNAMICS OF SOCIAL RELATIONSHIPS AND VOCAL COMMUNICATION BETWEEN INDIVIDUALS AND SOCIAL UNITS OF SPERM WHALES
(2012-12-17)Within-population behavioural variation can greatly affect the ecology of a species and the outcome of evolutionary processes. This study aimed to determine how variable sperm whale social and vocal behaviour is between ... -
On the entire cyclic cohomology of Banach algebras.
(Dalhousie University, 1991) -
On the estimation of return periods from short sea level records.
(Dalhousie University, 1993) -
On the heterogeneity of negative priming effects.
(Dalhousie University, 2003) -
On the Importance of the Study of Past Connectivity to Understand Present and Future Patterns in a Freshwater Fish
(2018-08-13)Conceptually, in evolution, the variable “time” is fundamental. Extant populations are the result of long- and short-term historical processes affecting them through time. Populations in areas near the poles have been ... -
On the influence of private stakeholders in the governance of international tuna fisheries
(2021-08-09)Twenty-three populations of tuna are globally distributed across national waters and the high seas. These fish are caught by hundreds of fishing fleets, which operate in a complex governance system, influenced by national ... -
On the information processing dynamics of inhibition of return.
(Dalhousie University, 2003) -
On the inhibitory consequences of visuospatial orienting: Inhibition of return?
(2016-02-29)Responding is typically slowest toward (an “output” bias) or about (an “input” bias) targets presented at the location indicated by a spatially uninformative visual transient (a “cue”) when the onset asynchrony between the ... -
On the interplay between society and culture: causes, consequences and stability of sperm whale clans
(2016-08-29)The overarching goal of my thesis is to formalize the interplay between animal society and culture, using sperm whales as a model. Sperm whales live in multilevel societies, characterized by cooperation and social learning. ... -
On the Melt Rate of Submerged Sediment-Laden Ice
(2013-08-27)Submerged sediment-laden ice blocks that form on the intertidal mud flats of the Minas Basin pose a potential threat to tidal turbines planned for deployment in the Minas Passage. Laboratory prepared ice blocks of varying ... -
On the Neighbourhood Polynomial
(2017-04-07)The neighbourhood polynomial of a graph is the generating function for the neighbourhood complex, which contains all subsets of vertices which have a common neighbour. We begin with some formulas for computing the neighbourhood ... -
On the Post-printing Heat Treatment of Wire Arc Additively Manufactured Ferrous Alloys
(2022-04-14)Over the past decade, wire arc additive manufacturing has become a promising alternative to conventional manufacturing methods due to its great potential for fabrication of medium to large size components with high deposition ... -
ON THE PREDICTION ACCURACY OF THE MID-TERM ELECTRICITY PRICES USING OPTIMIZED SUPPORT VECTOR MACHINE
(2016-08-17)In the modern electricity market, it is crucial to have precise electricity price forecasting. However, few studies have focused on this area. Mid-term electricity price forecasting (MTEPF) has numerous applications, such ...
