2. 21. On Sustainability in Local Energy Planning

   Author : Farhad Derakhshan; Energihushållning; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Indicators; Sustainable Development; Energy Systems; Energy Planning;

   Abstract : Energy is among the main driving forces needed for sustainable development. Provision of energy services, from the supply side to transmission/distribution and use, must include management, and good management requires tools. Energy planning is a tool for managing the community energy system through assessing and balancing supply and demand. READ MORE

4. 22. Public Transportation in a Systems Perspective A Conceptual Model and an Analytical Framework for Design and Evaluation

   Author : Stig Franzén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control theory; systems design; cybernetics; passenger transport; urban transport; systems perspective; conceptual model; systems engineering; human-machine system; public transportation;

   Abstract : Today urban areas are faced with problems like traffic congestion, air pollution, and limited accessibility and transport policy issues are focused on the "sustainable city of the future". For decision-makers the crucial question is how, with limited financial resources, a system for public transportation should be designed and developed to provide attractive travel and transport services.

5. 23. Inverse Problems in Analytic Interpolation for Robust Control and Spectral Estimation

   Author : Johan Karlsson; Anders Lindquist; Alberto Isidori; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nevanlinna-Pick Interpolation; Approximation; Model Reduction; Robust Control; Gap-robustness; Sensitivity Shaping; Entropy functional; Spectral Estimation; Weak*-topology; Monge-Kantorovic Transportation; Optimization; systems theory; Optimeringslära; systemteori;

   Abstract : This thesis is divided into two parts. The first part deals with theNevanlinna-Pick interpolation problem, a problem which occursnaturally in several applications such as robust control, signalprocessing and circuit theory. We consider the problem of shaping andapproximating solutions to the Nevanlinna-Pick problem in a systematicway. READ MORE

   Author : Toheed Ghandriz; 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; automation; electrified propulsion; long combination vehicles; electromobility; propulsion system tailoring; automated driving systems; optimal control; single-track and two-track vehicle models; predictive energy management and vehicle stability; motion control; longer heavier vehicles; vehicle stability; optimal energy management; total cost of ownership; optimization; transportation mission; heterogeneous heavy vehicle fleet; fleet sizing;

   Abstract : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. READ MORE

7. 25. On the integration of optimization and agent technology for transportation and production planning

   Author : Johan Holmgren; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis concerns the integration of agent technology and mathematical optimization for improved decision support within the domain of analysis and planning of production and transportation. These two approaches have often been used separately in this domain but the research concerning how to combine them is very limited. READ MORE
