  1. 1. Energy system operation by Lagrangian relaxation

    Author : Erik Dotzauer; Andrew B. Philpott; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Due to its relatively high total energy efficiency, the application of cogeneration, i.e. simultaneous exploitation of power and heat from the energy transformation process, is receiving increased attention. In many countries cogeneration is today an essential element in the energy supply system. READ MORE

  2. 2. Marginal Productivity Indices and Linear Programming Relaxations for Dynamic Resource Allocation in Queueing Systems

    Author : Jianhua Cao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Markov decision process; Indexability; Linear programming; Queueing theory; Optimization;

    Abstract : Many problems concerning resource management in modern communication systems can be simplified to queueing models under Markovian assumptions. The computation of the optimal policy is however often hindered by the curse of dimensionality especially for models that support multiple traffic or job classes. READ MORE

  3. 3. Computation of Autonomous Safety Maneuvers Using Segmentation and Optimization

    Author : Pavel Anistratov; Lars Nielsen; Björn Olofsson; Jan Åslund; Jonas Fredriksson; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis studies motion planning for future autonomous vehicles with main focus on passenger cars. By having automatic steering and braking together with information about the environment, such as other participants in the traffic or obstacles, it would be possible to perform autonomous maneuvers while taking limitations of the vehicle and road–tire interaction into account.

  4. 4. MULTICOMPONENT SPRAY-TURBULENCE INTERACTION

    Author : Vignesh Pandian Muthuramalingam; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasoline diesel blend; CFD; multicomponent fuel sprays; ethanol iso-octane blend; Stochastic Blob and Bubble VSB2 spray model; direct injection engines;

    Abstract : Blended fuels are gaining importance in automotive industry owing to stringent legislations for emissions. It is important to understand the fuel spray formed as a consequence of injecting blended fuels into the engine (for direct injection engines) and also the influence of fuel spray on combustion properties.

  5. 5. Convex Optimization for Assignment and Generalized Linear Regression Problems

    Author : Efthymios Tsakonas; Björn Ottersten; Ami Wiesel; KTH; []
    Keywords : ;

    Abstract : This thesis considers optimization techniques with applications in assignment and generalized linear regression problems. The first part of the thesis investigates the worst-case robust counterparts of combinatorial optimization problems with least squares (LS) cost functions, where the uncertainty lies on the linear transformation of the design variables.
