2. 1. Logistics-based Competition : A Business Model Approach

   Author : Tobias Kihlén; Mats Abrahamsson; Daniel Kindström; Andreas Norrman; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; logistics-based competition; business model; logistics strategy; strategy; logistics; Business and economics; Ekonomi;

   Abstract : Logistics is increasingly becoming recognised as a source of competitive advantage, both in practice and in academia. The possible strategic impact of logistics makes it important to gain deeper insight into the role of logistics in the strategy of the firm. READ MORE

4. 2. Model-based execution monitoring

   Author : Marcus Bjäreland; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Abstract : The task of monitoring the execution of a software-based controller in order to detect, classify, and recover from discrepancies between the actual effects of control actions and the effects predicted by a model, is the topic of this thesis. Model-based execution monitoring is proposed as a technique for increasing the safety and optimality of operation of large and complex industrial process controllers, and of controllers operating in complex and unpredictable environments (such as unmanned aerial vehicles).

5. 3. Model-Based Optimization of Combustion-Engine Control

   Author : Gabriel Turesson; Institutionen för reglerteknik; []
   Keywords : Model Predictive Control MPC ; Partially Premixed Combustion; Pressure Sensor Feedback; Model Based Control; Particle Filter; Multiple Fuel Injections; Gasoline Compression Ignition; Model Predictive Control MPC ; Partially Premixed Combustion PPC ; Low Temperature Combustion; Model Based Control; Multiple Fuel Injections; Pressure Sensor Feedback; Particle Filter; Gasoline Compression Ignition;

   Abstract : The work presented in this thesis is motivated by the need to reliably operate a compression-ignition engine in a partially premixed combustion (PPC) mode. Partially premixed combustion is a low temperature combustion concept, where the ignition delay is prolonged to enhance fuel-air mixing in the combustion chamber before the start of combustion.

6. 4. Numerical simulation and analysis of multi-scale cavitating flows using a hybrid mixture-bubble model

   Author : Ebrahim Ghahramani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Homogeneous mixture model; Lagrangian bubble model; CFD; Cavitation; OpenFOAM; Multiphase flow; Hybrid model; Multi-scale;

   Abstract : The aim of this research is to model and analyse multi-scale cavitating flows with a certain emphasis on small sub-grid vapour structures. Cavitating flows include vapour structures with different length scales, from micro-bubbles to large cavities. READ MORE

7. 5. Synthesis of a Model-based Tire Slip Controller

   Author : Stefan Solyom; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LMI; synthesis; hybrid; piecewise linear; ABS; PID;

   Abstract : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. READ MORE
