    Abstract : The demand for higher data rates and efficient use of various resources has been an unquenchable thirst across different generations of cellular systems, and it continues to be so. Aggressive reuse of frequency resources in cellular systems gives rise to intercell interference which severely affects the data rate of users at the cell-edge. READ MORE

    Abstract : Following unprecedented earthquakes in 1999, highly centralized Turkey initiated reforms that aimed to improve disaster management collaboration and to empower local authorities. In 2011, two earthquakes hit the country anew affecting the city of Van and town of Erciş in Turkey’s southeast. READ MORE

  5. 3. Fuel-Efficient Centralized Coordination of Truck Platooning

    Author : Sebastian van de Hoef; Dimos V. Dimarogonas; Rudy Negenborn; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The problem of how to coordinate a large fleet of trucks with given itinerary to enable fuel-efficient platooning is considered. Platooning is a promising technology that enables trucks to save significant amounts of fuel by driving close together and thus reducing air drag. READ MORE

  6. 4. Centralized Ovarian Cancer Care - Complications, Costs and Survival

    Author : Charlotte Palmqvist; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovarian cancer; Survival; Centralization; Surgery; Cytoreduction; Residual disease; Postoperative complications; Cost of illness; Direct costs; Indirect cost; Epidemiology;

    Abstract : Background: Ovarian cancer is often diagnosed at advanced stages, and its mortality is high. Surgical treatment of advanced ovarian cancer strives toward complex primary debulking surgery (PDS), aiming for complete cytoreduction (R0) and improved survival. READ MORE

  7. 5. Radio resource management for wireless indoor communication systems : performance and implementation aspects

    Author : Stefan Pettersson; KTH; []
    Keywords : Radio resource management; indoor communication; the bunch concept; centralized RRM; dynamic channel allocation; channel selection;

    Abstract : In this thesis, we investigate several radio resourcemanagement (RRM) techniques and concepts in an indoorenvironment with a dense infrastructure. Future wireless indoorcommunication networks will very likely be implemented atplaces where the user concentration is very high. At these hotspots, the radio resources must be used efficiently.
