  1. 16. Optimization-Based Methods for Revising Train Timetables with Focus on Robustness

    Författare :Fahimeh Khoshniyat; Jan Lundgren; Johanna Törnquist Krasemann; Steven Harrod; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With increase in the use of railway transport, ensuring robustness in railway timetables has never been this important. In a dense railway timetable even a small disturbance can propagate easily and affect trains' arrival and departure times. In a robust timetable small delays are absorbed and knock-on effects are prevented effectively. LÄS MER

  3. 17. Optimisation models for train timetabling and marshalling yard planning

    Författare :Sara Gestrelius; Anders Peterson; Martin Aronsson; Pieter Vansteenwegen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Railways provide high capacity, safe and energy efficient transportation of goods and passengers. However, railway transportation also suffers from intrinsic restrictions and the effectiveness and efficiency of the transportation depend on the railway actors’ ability to solve a set of hard and interconnected planning problems.

  4. 18. Production Planning of CHP plants in transition towards energy systems with high share of renewables

    Författare :Mahsa Daraei; Eva Thorin; Pietro Elia Campana; Anders Avelin; Louise Ödlund; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The global energy system is undergoing a transformative change towards renewable energies. The share of Renewable Energy Sources (RES) and bioenergy in the world’s primary energy use has increased in the recent years. LÄS MER

  5. 19. Computational Modeling of Cancer Progression

    Författare :Hossein Shahrabi Farahani; Jens Lagergren; Niko Beerenwinkel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer progression; Bayesian networks; microRNA editing; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : Cancer is a multi-stage process resulting from accumulation of genetic mutations. Data obtained from assaying a tumor only contains the set of mutations in the tumor and lacks information about their temporal order. Learning the chronological order of the genetic mutations is an important step towards understanding the disease. LÄS MER

  7. 20. On the use of process integration methods : evaluation of energy and CO2 emission strategies in blast furnace ironmaking and oxygen steelmaking

    Författare :Christer Ryman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : This work deals with sustainable resource utilisation in integrated (iron ore based) steelmaking, with special emphasis on how to analyse process adaptation and developments aiming towards lowering of the emission of greenhouse gases, in particular carbon dioxide (CO2), to the atmosphere. Climate change and management of CO2 are real issues for the steel industry these days. LÄS MER
