On cultural inheritance: Evolution, behaviour and social structure of Eastern Caribbean sperm whales
(2022-08-25)Cultural inheritance is a “second inheritance system” which can affect ecology and evolution in unexpected ways. However, although its implications in humans are recognized and extensively studied, cultural inheritance has ... -
On Demand: Digital Platforms & Class Conflict in the Gig Economy
(2022-08-29)The gig economy represents an ongoing shift in the world of work and can be understood as the most recent attempt by Capital as a class to dominate and undermine the power of workers, collectively known as Labour. Since ... -
ON DEVELOPMENTAL VARIATION IN HIERARCHICAL SYMBIOTIC POLICY SEARCH
(2012-08-27)A hierarchical symbiotic framework for policy search with genetic programming (GP) is evaluated in two control-style temporal sequence learning domains. The symbiotic formulation assumes each policy takes the form of a ... -
On Dominating Sets and the Domination Polynomial
(2021-08-31)A dominating set S of a graph G of order n is a subset of the vertices of G such that every vertex is either in S or adjacent to a vertex of S. The domination polynomial is denoted by D(G,x) is the generating polynomial ... -
On Double Inverse Semigroups
(2013-08-21)A double semigroup is a set equipped with two associative binary operations satisfying the middle-four interchange law. A double inverse semigroup is a double semigroup in which both operations are inverse semigroup ... -
On Holder continuity of weak solutions to degenerate linear elliptic partial differential equations
(2013-08-21)For degenerate elliptic partial differential equations, it is often desirable to show that a weak solution is smooth. The first and most difficult step in this process is establishing local Hölder continuity. Sufficient ... -
On Hopf algebra extensions and cohomologies.
(Dalhousie University, 2002) -
On Improving The Oxidation Resistance Of A Nickel-Based Superalloy Produced By Powder Metallurgy
(2012-08-16)Nickel-based Superalloys are widely used in the steam turbine power generation and aerospace industries. They possess the desirable qualities of high-temperature strength, oxidation and corrosion resistance and can operate ... -
On Increasing the Scope of Genetic Programming Trading Agents
(2020-07-17)This research investigates the potential for widening the scope of Genetic Programming (GP) trading agents beyond constructing decision trees for buy-hold-sell decisions. First, both technical indicators (temporal feature ... -
On Light and Matter: Structural Optics of Biomaterials
(2022-04-12)The wings of a morpho butterfly exhibit a dazzling display of crystalline blue that transforms with viewing angle. The optical properties demonstrated by this improbable blue are produced not by pigment but as a function ... -
On measurably indexed families of Hilbert spaces.
(Dalhousie University, 1992) -
On Models for Detecting Evidence of Molecular Adaptation in Homologous Sequences of Protein Coding Genes
(2019-08-30)Codon substitution models (CSMs) are commonly fitted to alignments of homologous protein-coding sequences with the objective of determining whether sites in the gene underwent positive selection. Under the standard paradigm ... -
On Network Reliability
(2013-06-24)The all terminal reliability of a graph G is the probability that at least a spanning tree is operational, given that vertices are always operational and edges independently operate with probability p in [0,1]. In this ... -
On Northern Hemisphere climate change and variability during the last half of the 20th century.
(Dalhousie University, 2004) -
On simplified predictive control via IP networks.
(Dalhousie University, 2006) -
On Sustainable Supply Chains: Optimal Design of a Multimodal Logistics Network with Shipment Consolidation, Stochastic Demand, and Machine Learning
(2022-08-15)In this thesis, we consider the logistics network of a multi-echelon multimodal supply chain with multiple products and components taking economic and environmental sustainability, and shipment consolidation into consideration. ... -
On the "Poverty of Responsibility": A Study of the History of Child Protection Law and Jurisprudence in Nova Scotia
(2015)This thesis presents a history of child protection law and jurisprudence in Nova Scotia. The thesis begins by examining the development of the first child protection statute in Canada, the Nova Scotia Prevention and ... -
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 ...
