1. Extensions in Flux : An Essay on Vagueness and Context Sensitivity
Sammanfattning : The extensions of vague predicates like ‘is bald’, ‘is tall’, and ‘is a heap’ apparently lack sharp boundaries, and this makes such predicates susceptible to soritical reasoning, i.e. reasoning that leads to some version of the notorious sorites paradox. LÄS MER
2. Dose Plan Optimization in HDR Brachytherapy using Penalties : Properties and Extensions
Sammanfattning : High dose-rate (HDR) brachytherapy is a specific type of radiotherapy used to treat tumours of for example the cervix, prostate, and breasts. In HDR brachytherapy applicators are implanted into or close to the tumour volume. A radioactive source is moved through these applicators and stops at certain positions, known as dwell points.

3. Extensions of general relativity : scalar tensor theory, topology of space-time and supergravity
Sammanfattning : This report together with Papers 1—11 constitute a dissertation on the subjects of Scalar Tensor Theories, Topology of Space-Time and Supergravity. These three areas are briefly introduced for providing a background to the work in 1—11. A general discussion of motivations for modifications of the Einstein theory is also offered. . LÄS MER
4. Extensions of Deontic Logic : An Investigation into some Multi-Modal Systems
Sammanfattning : Deontic logic is a branch of logic that deals with normative concepts, propositions, arguments and systems. The main purpose of this compilation thesis is to investigate how deontic logic can be extended in a number of ways. We consider several multimodal systems, i.e. LÄS MER
5. On Hom-associative Ore Extensions
Sammanfattning : In this thesis, we introduce and study hom-associative Ore extensions. These are non-unital, non-associative, non-commutative polynomial rings in which the associativity condition is “twisted” by an additive group homomorphism. LÄS MER
