  2. 11. Improving Timetable Robustness and Punctuality of Railway Traffic : A Combined Simulation-Optimization Approach for Nonperiodic Timetabling on Double-Track Lines

    Author : Johan Högdahl; Markus Bohlin; Oskar Fröidh; Rob Goverde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timetabling; Train scheduling; Delay prediction; Punctuality; Railroad; Robustness; Transportsystem; Transport Systems;

    Abstract : To evaluate the robustness of a timetable against minor delays, it can be simulated. A natural question following a simulation is how the results can be used to improve the timetable, which has received limited attention in the literature. READ MORE

  4. 12. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables

    Author : Johan Högdahl; Markus Bohlin; Oskar Fröidh; Alireza Ahmadi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railroad; Timetabling; Optimization; Simulation; Robustness; Punctuality; Delay prediction.; Järnväg; Tidtabelläggning; Optimering; Simulering; Robusthet; Punktlighet; Förseningsprediktion.; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Abstract : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. READ MORE

  5. 13. A Model Based Approach to Robustness Analysis and Optimisation of Chromatography Processes

    Author : Niklas Jakobsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Langmuir; SMA; Optimisation; Robustness; Chromatography; Prepartive process scale; Modelling;

    Abstract : One of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. READ MORE

  6. 14. Uncertainty, Robustness and Sensitivity Reduction in the Design of Single Input Control Systems

    Author : Kjell Nordström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty; Robustness; Sensitivity; Single input control systems;

    Abstract : Feedback control of systems modelled as single input, time invariant, linear and continuous time systems is the subject of this thesis. A growing interest in the design of feedback control systems that can cope with model uncertainties has been the motivation for the study. READ MORE

  7. 15. Robustness analysis of eukaryotic signal transduction with emphasis on the HOG pathway in Saccharomyces cerevisiae

    Author : Lars-Göran Ottosson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; systems biology; robustness; gTOW; signal transduction; MAPK signalling; HOG; kinase; phosphatase; transcription factor;

    Abstract : Fundamental to life, in particular for unicellular microorganisms that generally are subjected to rapidly changing environmental parameters, is the need to monitor and integrate environmental stimuli with the internal cell status. The sensing of stimuli are typically initiated at the plasma membrane and then transmitted by means of intracellular signalling networks to elicit proper cellular responses. READ MORE
