1. Modeling Width in Spatial Optimization in Raster Space
Sammanfattning : Given a grid of cells, each of which is assigned a numerical value quantifying its utility (or cost) for a certain use, a popular type of problem in geographic information science is raster-based spatial optimization. Such problems commonly seek to find a set of cells that maximizes (or minimizes) that utility (or cost) while adhering to a given set of constraints. LÄS MER
2. Robust optimization of radiation therapy accounting for geometric uncertainty
Sammanfattning : Geometric errors may compromise the quality of radiation therapy treatments. Optimization methods that account for errors can reduce their effects.The first paper of this thesis introduces minimax optimization to account for systematic range and setup errors in intensity-modulated proton therapy.

3. Shape Optimization for Acoustic Wave Propagation Problems
Sammanfattning : Boundary shape optimization is a technique to search for an optimal shape by modifying the boundary of a device with a pre-specified topology. We consider boundary shape optimization of acoustic horns in loudspeakers and brass wind instruments. LÄS MER
4. Heat decarbonization in municipalities - Accounting for the local spatial context in techno-economic modeling
Sammanfattning : In Europe, 57% of the energy used for space and water heating is derived from the combustion of fossil fuels, whereas only 24% comes from renewables. Compared to the wide-reaching transmission of electricity between countries, the supply of heat predominantly occurs at the local or individual level. LÄS MER
5. On Distributed Optimization in Networked Systems
Sammanfattning : Numerous control and decision problems in networked systems can be posed as optimization problems. Examples include the framework of network utility maximization for resource allocation in communication networks, multi-agent coordination in robotics, and collaborative estimation in wireless sensor networks (WSNs).
