  2. 16. Model Based Optimization of a Complete Diesel Engine/SCR System

    Author : Claes Ericson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPC; model based optimization; real time models; model based control; SCR; optimization; EGR;

    Abstract : Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions.

  4. 17. On Some Combinatorial Optimization Problems : Algorithms and Complexity

    Author : Hannes Uppman; Peter Jonsson; Christer Bäckström; Ulf Nilsson; Stanislav Živný; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational complexity; optimization; constraint satisfaction problem;

    Abstract : This thesis is about the computational complexity of several classes of combinatorial optimization problems, all related to the constraint satisfaction problems.A constraint language consists of a domain and a set of relations on the domain. For each such language there is a constraint satisfaction problem (CSP). READ MORE

  5. 18. Energy systems analysis of Swedish pulp and paper industries from a regional cooperation perspective : Case study modeling and optimization

    Author : Sofia Klugman; Bahram Moshfegh; Thore Berntsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy system; Optimization; District heating; Energy audit; Co-operation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The industrial sector uses about one third of the energy end-use in the world. Since energy use in many cases highly affects both the local and global environment negatively, it is of common interest to increase energy efficiency within industries. READ MORE

  6. 19. Erectile dysfunction in clinical practice. - With special focus on the correlation to myocardial infarction, lower urinary tract symptoms (LUTS), treatment cost and optimization -

    Author : Peter Ströberg; Göteborgs universitet; []
    Keywords : Erectile Dysfunction; Cardiovascular disease; ; LUTS; Cost; Treatment optimization; Preference; Clinical practice;

    Abstract : The purpose of this thesis was to study and evaluate some aspects of Erectile Dysfunction (ED) in clinical practice, with special focus on the correlation to myocardial infarction, LUTS (lower urinary tract symptoms), ED treatment costs and optimization. A group of 100 patients under the age of 70 years who had suffered their first MI and an age matched control group without MI answered a questionnaire regarding ED and concomitant diseases.
