  1. 1. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Rasmus Bokrantz; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; multicriteria optimization; robust optimization; Pareto optimality; Pareto surface approximation; Pareto surface navigation; intensity-modulated radiation therapy; volumetric-modulated arc therapy; intensity-modulated proton therapy; Optimering; flermålsoptimering; robust optimering; Paretooptimalitet; Paretofrontsapproximation; Paretofrontsnavigering; intensitetsmodulerad strålterapi; rotationsterapi; intensitetsmodulerad protonterapi;

    Sammanfattning : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. LÄS MER

  2. 2. Multiobjective optimization in engineering design : applications to fluid power systems

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Johan Andersson; Linköpings universitet.; Linköpings universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on how to improve design and development of complex engineering systems by employing simulation and optimization techniques. Within the thesis, methods are developed and applied to systems that combine mechanical, hydraulical and electrical subsystems, so-called multi-domain systems. LÄS MER

  3. 3. Automated Bottleneck Analysis of Production Systems Increasing the applicability of simulation-based multi-objective optimization for bottleneck analysis within industry

    Detta är en avhandling från Skövde : University of Skövde

    Författare :Jacob Bernedixen; Högskolan i Skövde.; Högskolan i Skövde.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bottleneck analysis; bottleneck identification; bottleneck improvement; multi-objective optimization; simulation; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Manufacturing companies constantly need to explore new management strategies and new methods to increase the efficiency of their production systems and retain their competitiveness. It is of paramount importance to develop new bottleneck analysis methods that can identify the factors that impede the overall performance of their productionsystems so that the optimal improvement actions can be performed.

  4. 4. Tracking Area Planning in Cellular Networks Optimization and Performance Evaluation

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sara Modarres Razavi; Linköpings universitet.; Linköpings universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The enormous competition in the telecommunications market results in the necessity of optimized and cost-efficient networks for the operators and service providers. Tracing users cost-efficiently is one of the major challenges in the study of location management of wireless cellular  networks. LÄS MER

  5. 5. Planning and Optimization of Tracking Areas for Long Term Evolution Networks

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Sara Modarres Razavi; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Along with the evolution of network technologies, user’s expectations on performance and mobile services are rising rapidly. To fulfill the customer demands the operators are facing a great amount of network signaling overhead in terms of Location Management (LM), which tracks and pages User Equipments (UEs) in the network.
