1. Optimal and Hereditarily Optimal Realizations of Metric Spaces
Abstract : This PhD thesis, consisting of an introduction, four papers, and some supplementary results, studies the problem of finding an optimal realization of a given finite metric space: a weighted graph which preserves the metric's distances and has minimal total edge weight. This problem is known to be NP-hard, and solutions are not necessarily unique. READ MORE

2. Optimal tax mixes
Abstract : The three self-contained papers and the note that constitute this thesis analyze the structure of optimal tax mixes in a general-equilibrium economy of heterogeneous individuals incorporating the issue of optimal provision of a pure public good in the last two papers. Paper I deals with the topics in an atemporal model of two individuals differing in their innate production abilities for different policy objectives using a Cobb-Douglas utility function. READ MORE

3. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions
Abstract : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. READ MORE

4. Optimal Truck Scheduling : Mathematical Modeling and Solution by the Column Generation Principle
Abstract : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. READ MORE

5. Optimal Control of Partial Differential Equations in Optimal Design
Abstract : This thesis concerns the approximation of optimally controlled partial differential equations for inverse problems in optimal design. Important examples of such problems are optimal material design and parameter reconstruction. In optimal material design the goal is to construct a material that meets some optimality criterion, e.g. READ MORE
