1. 16. Processes in Optical Diesel Engines - Emissions Formation and Heat Release

   Författare :Ulf Aronsson; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Engines; Optical Engines; Heat Release; Combustion; Emissions Formation; Mechanical Deformation;

   Sammanfattning : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. LÄS MER

3. 17. Electrochemical machining: towards 3D simulation and application on SS316

   Författare :A. A. Gomez-Gallegos; UK University of Edinburgh; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical machining; 3D Simulation; FEM; stainless Steel 316; surface Finish; Maskinteknik; Mechanical Engineering;

   Sammanfattning : Electrochemical machining (ECM) is a non-conventional manufacturing process, which uses electrochemical dissolution to shape any conductive metal regardless of its mechanical properties and without leaving behind residual stresses or tool wear. Therefore, ECM can be an alternative for machining difficult-to-cut materials, complex geometries, and materials with improved characteristics, such as strength, heat-resistance or corrosion-resistance.

4. 18. Estimation of the In-Cylinder Air/Fuel Ratio of an Internal Combustion Engine by the Use of Pressure Sensors

   Författare :Per Tunestål; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; hydraulik; Maskinteknik; nonlinear; cylinder pressure; engine; least-squares; Mechanical engineering; estimation; hydraulics; vibration and acoustic engineering; vacuum technology; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem;

   Sammanfattning : This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. LÄS MER

5. 19. One-piece fashion : Demand driven supply chain management

   Författare :Jonas Larsson; Högskolan i Borås; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fashion logistics; mass customisation; supply chain management; knitwear; agility; demand chain management; Fashion Management;

   Sammanfattning : The fashion market is characterised by short life cycles, low predictability, and high impulse purchasing. In order to respond to these characteristics, companies are constantly introducing new collections and models. LÄS MER

7. 20. Car Compatibility in Frontal Crashes: New Methods to Determine the Influence of Mass, Structure, Stiffness, and Geometry, and their Interactions on Injuries

   Författare :Dagmar Buzeman Jewkes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass compatibility; integrated vehicle-occupant model; injury risk; structural integrity; stiffness compatibility; frontal offset crash;

   Sammanfattning : Vehicle-to-vehicle crash compatibility affects vehicle compartment acceleration and intrusion, which are the two main causes of car occupant injuries. A better understanding of compatibility effects is needed to establish safety priorities and improve occupant and partner protection. LÄS MER
