2. 1. Structure-Acoustic Analysis; Methods, implementations and applications

   Author : Per-Anders Wernberg; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; numerical; Mechanical engineering; finite element ; Structure-Acoustic ; vakuumteknik; vibrationer; akustik; Maskinteknik; hydraulik;

   Abstract : This thesis investigates structure-acoustic problems, which involve a flexible structure coupled to an enclosed acoustic fluid. In the literature, this type of problem is usually referred to as vibroacoustic problems or structure-acoustic problems with fluid interaction. The thesis consists of two parts. READ MORE

4. 2. Perceived Quality of Cars. A Novel Framework and Evaluation Methodology

   Author : Kostas Stylidis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; luxury; knowledge management; engineering; premium; design; engineering; automotive; product quality; ; product development; aesthetics; perceived quality;

   Abstract : The supremacy of the automotive manufacturers today is no longer driven by them achieving a superior manufacturing quality but increasingly depends on the customer’s quality perception. Average car consumers see a car’s quality as a fancy mixture of design, aesthetics, their own previous experiences and performance characteristics of the vehicle, unlike a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved in the modern car creation.

5. 3. Railway wheel steel behaviour upon thermo-mechanical loadings

   Author : Erika Steyn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual stress; thermo-mechanical fatigue; railway wheel steel; pearlitic microstructure; severe block braking; repair welding;

   Abstract : Optimised railway maintenance techniques such as rail grinding and milling, or rail repair welding, are vital to more sustainable rail networks. As demands on the railway increases, the need to better understand the material behaviour during local heating events occurring during maintenance is amplified. READ MORE

6. 4. Meso-Mechanical Modeling and Analysis of Adhesive Layers

   Author : Kent Salomonsson; Ulf Stigh; Per Ståhle; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive layer; Meso-mechanical; Representative Volume Element; Large curvatures; Interphase elements; Evolution algorithm; Engineering mechanics; Teknisk mekanik; Technology; Teknik;

   Abstract : This thesis is concerned with the modeling, simulation and analysis of adhesive layers. By use of an in situ scanning electron microscopy study it is found that the adhesive studied in the present thesis has a very complex structure with two different compounds, a mineral and an epoxy/thermoplastic blend.

7. 5. Market structure and economic status for firms producing single-family houses in Sweden

   Author : Fredrik Lindblad; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wooden Houses; Wooden single-family houses; Wooden multi- family houses; Financial Performance; Risk Position; Economic distress; Z- score model; Industry Structure; Productivity; Off-site construction; Industry concentration; Maskinteknik; Mechanical Engineering;

   Abstract : The gradually changing behavior of the population, towards urbanization, ledto an increased shortage of available housing. This development has resultedin a serious issue in Sweden, where too few firms are providing solutions formulti-family houses in wood. READ MORE
