2. 6. A study of vehicle fatigue damage predictions based on state estimations

   Author : Ulrika Lagerblad; Artem Kulachenko; Henrik Wentzel; Costas Papadimitriou; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; State estimations; Fatigue damage; Damage predictions; Fixed-lag Kalman Smoother; Hållfasthetslära; Solid Mechanics;

   Abstract : Individual health monitoring of heavy vehicles is one of the keystones on which an optimized utility of a vehicle fleet is based. For many components mounted on the chassis of a heavy vehicle, failures due to fatigue is a major concern. READ MORE

4. 7. Testing for Rationality, Separability and Efficiency

   Author : Per Hjertstrand; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Revealed preference; Regional convergence; Rationality; Nonparametric; NONPAR test; LP test; GARP; Efficiency; Data Envelopment Analysis DEA ; Afriat’s Theorem; Bootstrap; Swofford and Whitney test; Weak separability;

   Abstract : This thesis aims to propose, evaluate and apply test procedures for rationality, weak separability and efficiency. In particular, it focuses on nonparametric revealed preference procedures. READ MORE

5. 8. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping

   Author : Lisbeth Hellström; Torbjörn Carlberg; Per Engstrand; Sören Östlund; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood chipping; Chip formation; Digital Speckle Photography; Friction; Fracture Processes; Analytical model; Laboratory Wood Chipper; Force Measurement; Vibration Synthesis; Energy Efficiency; Chip Damage; TMP; CTMP; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. READ MORE

   Author : Sarah Tell; Raid Karoumi; Ülker-Kaustell Mahir; Andreas Andersson; Bill F. Jr. Spencer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; vibration mitigation; railway bridge; high-speed trains; bridge deck acceleration; passive damping; fluid viscous dampers; retrofit; dynamik; vibrationsdämpning; järnvägsbro; höghastighetståg; brobaneacceleration; passiv dämpning; viskösa dämpare; eftermontering; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : At the moment of writing, an expansion of the Swedish railway network has started, by constructions of new lines for high-speed trains. The aim is to create a high-speed connection between the most populous cities in Sweden - Stockholm, Göteborg and Malmö, and the rest of Europe. READ MORE

7. 10. Storage Stability and Phase Separation Behaviour of Polymer-Modified Bitumen : Characterization and Modelling

   Author : Jiqing Zhu; Niki Kringos; Dallas Little; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer-modified bitumen; Storage stability; Phase separation; Fluorescence microscopy; Phase-field modelling; Polymermodifierad bitumen; Lagringsstabilitet; Fasseparation; Fluorescensmikroskopi; Fas-fälts modellering; Transportvetenskap; Transport Science;

   Abstract : Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. READ MORE
