1. Progress in Hierarchical Clustering & Minimum Weight Triangulation
Sammanfattning : In this thesis we study efficient computational methods for geometrical problems of practical importance and theoretical interest. The problems that we consider are primarily complete linkage clustering, minimum spanning trees, and approximating minimum weight triangulation. Below is a list of the main results proved in the thesis. LÄS MER
2. Self-Organizing Logical-Clustering Topology for Managing Distributed Context Information
Sammanfattning : Internet of Things (IoT) is on the verge of experiencing a paradigm shift, the focus of which is the integration of people, services, context information, and things in the Connected Society, thus enabling Internet of Everything (IoE). Hundreds of billions of things will be connected to IoT/IoE by 2020. LÄS MER
3. Approximation and Online Algorithms with Applications in Computational Biology and Computational Geometry
Sammanfattning : The main contributions of this thesis are in the area of approximation and online algorithm design and derivation of lower bounds on the approximability for a number of combinatorial optimization problems with applications in computational biology and computational geometry. Approximation and online algorithms are fundamental tools used to deal with computationally hard problems and problems in which the input is gradually disclosed over time. LÄS MER
4. Effective Spatial Mapping for Coupled Code Analysis of Thermal–Hydraulics/Neutron–Kinetics of Boiling Water Reactors
Sammanfattning : Analyses of nuclear reactor safety have increasingly required coupling of full three dimensional neutron kinetics (NK) core models with system transient thermal–hydraulics (TH) codes. In order to produce results within a reasonable computing time, the coupled codes use two different spatial description of the reactor core. LÄS MER
5. You Bet! : An Investigation of Market Positioning by Online Gambling Firms and Drivers of their Customers’ Gambling Intention
Sammanfattning : Online gambling is a global multibillion dollar business that dwarfs all other forms of entertainment, and yet business and marketing research about it is scarce (Mizerski, 2013). The focus of gambling research has been on problem gamblers who ultimately represent a rather small, albeit important percentage of the gambling population. LÄS MER
