  1. 1. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation

    Author : Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Railway operation; Railway capacity; Single-track; Double-track; Partial double-track; Inter-station distance; Delay; Delay propagation; Crossing; Overtaking; Timetable flexibility; Simulation; Experimental design; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. READ MORE

  2. 2. Effects of Watershed Dynamics on Water Reservoir Operation Planning : Considering the Dynamic Effects of Streamflow in Hydropower Operation

    Author : Nicholas Zmijewski; Anders Wörman; Andrea Bottacin-Busolin; Francesca Pianosi; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir operation; dispersion processes; wave diffusion; multi-objective operation; water resource management; discharge variability; power spectrum analysis; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Water reservoirs are used to regulate river discharge for a variety of reasons, such as flood mitigation, water availability for irrigation, municipal consumption and power production purposes. Recent efforts to increase the amount of renewable power production have seen an increase in intermittent climate-variable power production due to wind and solar power production. READ MORE

  3. 3. The workings of co-operation : A comparative study of consumer co-operative organisation in Britain and Sweden, 1860-1970

    Author : Katarina Friberg; Peter Aronsson; Mary Hilson; Växjö universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; consumer co-operation; organisational logic; consumer demand; comparative method; retail trade; legislation for co-operation; household economy; History; Historia;

    Abstract : This thesis explores the workings of co-operation. It proceeds by way of a two-case comparative study, where the units of comparison are local consumer co-operatives: the Newcastle upon Tyne Co-operative Society Ltd., situated in the north-east of England, and Konsumentföreningen Solidar in Malmö, in the south-west of Sweden.

  4. 4. Numerical study on multi-pantograph railway operation at high speed

    Author : Zhendong Liu; Sebastian Stichel; Jens Nielsen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical study; pantograph-catenary system; multi-pantograph operation; dynamic behaviour; high-speed operation; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Abstract : Multi-pantograph operation allows several short electric multiple unit (EMU) trainsets to be coupled or decoupled to adapt to daily or seasonal passenger-flow variation. Although this is a convenient and efficient way to operate rolling stock and use railway infrastructure, pantographs significantly influence each other and even significantly change the dynamic behaviour of the system compared to single-pantograph operation in the same condition.

  5. 5. Co-operation in Vocational Rehabilitation employment : Methods in multiprofessional intersectorial group meetings and their effects on

    Author : Björn Jakobsson; Mittuniversitetet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keywords: Co-operation; communicative process; comparison groups; effects; employment; integration; multiprofessional rehabilitation; participant observation; sick-leave; unemployment; vocational rehabilitation.; Social medicine; Socialmedicin;

    Abstract : ABSTRACT Vocational rehabilitation is a complex process. As well as the client, it often involves the employer, medical professionals, national-insurance officials, employment counsellors from the employment office and social services officials. READ MORE
