2. 1. Some new results concerning general weighted regular Sturm-Liouville problems

   Author : Mervis Kikonko; Lars-Erik Persson; Peter Wall; Angelo B. Mingarelli; Alexey Karapetyants; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Partial differential equations; Sturm-Liouville problem; Right-definite; left-definite; non-definite; indefinite; Dirichlet problem; spectrum; eigenvalues; non-real eigenvalues; Richardson number; Richardson index; turning point; Mathematics; Matematik;

   Abstract : In this PhD thesis we study some weighted regular Sturm-Liouville problems in which the weight function takes on both positive and negative signs in an appropriate interval [a,b]. With such  problems there is the possible existence of non-real eigenvalues, unlike in the definite case (i.e. READ MORE

4. 2. Towards Changeability Quantification for Product-Service Systems Design

   Author : Raj Jiten Machchhar; Alessandro Bertoni; Johan Wall; Fredrik Elgh; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Changeability quantification; early design; Uncertainty; Value robustness; Operational Scenario; Product-Service Systems; Systems Engineering.; Maskinteknik; Mechanical Engineering;

   Abstract : Tough competition and volatile global markets have pushed the manufacturing industries to develop solutions more customer-centric with optimal utilization of resources. One of the key reasons behind developing a customer-centric solution is the increased customer value that imparts a competitive edge to the manufacturing industries, eventually leading them to sustain their businesses.

5. 3. Optimization Methods for Robust Control with Application to Resistive Wall Modes in Tokamaks

   Author : Carl-Magnus Fransson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H?; fusion; QFT; performance; tokamak; optimization; robustness; structured singular value; control; plasma; resistive wall modes; LMI; PID control;

   Abstract : In many research areas physical systems are described by mathematical models. We focus here on systems that are regulated by a controller, typically realized by software, whose design involves certain parameters. READ MORE

6. 4. Hanging wall stability of sublevel caving mines in Sweden

   Author : Alvaro Herdocia; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Mining with sublevel caving implies a drastic destruction of the ground surface in the area conforming the hanging wall of the mine. The extent of this affected zone is of little importance in unpopulated areas, but becomes of utmost economic significance when there are mine installations or a town site located on it. READ MORE

7. 5. Analyzing the properties and biosynthesis of β-glucans from Gluconacetobacter and poplar

   Author : Erik Malm; Vincent Bulone; Paul Dupree; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellulose synthesis; Bioinformatics; Proteomics; Cell wall;

   Abstract : Glucans are polysaccharides integral to many materials and biological functions. Under the umbrella of Biomime, the Swedish Center for Biomimetic Fiber Engineering, this work has aimed to improve basic understanding of the biosynthesis of such glucans. READ MORE
