  1. 6. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

    Författare :Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. LÄS MER

  3. 7. Size Estimation of Real-Time Software Components - A System Perspective

    Författare :Kenneth Lind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; COSMIC Function Points; software code size; Functional Size Measurement; software components; system architecture.;

    Sammanfattning : The demands and expectations on the system architectures of contemporary consumer products like cars are increasing for each product generation. New features using new sensors and actuators, with different variants on different markets, and that interact with other features, create additional complexity in the system. LÄS MER

  4. 8. Flickblickar : Visuella berättelser om, av och genom gymnasieelevers kroppar

    Författare :Maria Eriksson; Hillevi Gantez; Ketil Thorgersen; Helene Illeris; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gaze; femininity; girls; the body; visual narratives; visual culture; art education; images; reflexive ethnography; enactment; aesthetics; leisure time; utbildningsvetenskap med inriktning mot praktiska kunskapstraditioner; Educational Sciences in Arts and Professions;

    Sammanfattning : This thesis investigates enactments of femininities, bodies and images among young women in two art and design classes at urban Swedish upper-secondary schools. The theoretical framework combines visual culture, performativity and new materialism, contributing to art education research and girlhood studies. LÄS MER

  5. 9. Product support and spare parts considering system reliability and operating environment

    Författare :Behzad Ghodrati; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : The required spare parts planning for a system/machine is an integral part of the product support strategy. The number of required spare parts can be effectively estimated on the basis of the product reliability characteristics. LÄS MER

  7. 10. Multi-Echelon Inventory Control with General Backorder Cost Structures and Emissions

    Författare :Lina Johansson; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. LÄS MER
