  2. 1. Simulation of rail traffic : applications with timetable construction and delay modelling

    Author : Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). READ MORE

  4. 2. TM-rolling of heavy plate and roll wear

    Author : Mikael Jonsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Heavy plate;

    Abstract : The heavy plate rolling process needs accurate predictions of the process parameters. The plate thickness, flatness and rolling stability are of this direct influenced as well as the productivity. Therefore, careful calculation of the process parameters and pass schedules is necessary. READ MORE

  5. 3. Preoperative radiotherapy in rectal cancer : aspects of different regimens

    Author : David Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In Sweden approximately 2000 patients are annually diagnosed with a rectal cancer. The main treatment of the cancer is surgery. Radiotherapy (RT) is used as an adjuvant treatment in >60% of these patients to improve local control and in some patients to downsize a primary non resectable tumour to facilitate surgery.

  6. 4. Securing Clock Synchronization in Industrial Heterogeneous Networks

    Author : Elena Lisova; Mats Björkman; Christian Rohner; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Today, wireless solutions for industrial networks are becoming more and more appealing since they increase flexibility and enable the use of additional wireless sensors, but also bring such advantages as mobility and weight reduction. Wired networks, on the other hand, are reliable and, more importantly, already existing in most distributed control loops. READ MORE

  7. 5. Serotonergic and steroidal influences on impulsive behaviour in rats

    Author : John L. Evenden; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; impulsivity; serotonin; 8-OH-DPAT; DOI; steroid; testosterone; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : Impulsiveness is a trait contributing to the personality of all human beings to a greater and lesser extent. In a pathological form it can lead to impulsive behaviour which is an important component of many psychiatric and neurological disorders. READ MORE
