2. 1. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

   Author : Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

   Abstract : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. READ MORE

4. 2. Wind turbines over a hilly terrain: performance and wake evolution

   Author : Ann Hyvärinen; P. Henrik Alfredsson; Antonio Segalini; Leonardo P. Chamorro; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; wind turbines; complex terrain; wind-tunnel measurements; Strömningsmekanik; vindturbiner; komplex terräng; vindtunnelmätningar; Engineering Mechanics; Teknisk mekanik;

   Abstract : The aim of this licentiate thesis is to investigate wind-turbines placed in a complex-terrain environment. This is done by studying the flow around small-scale wind-turbine models placed over a landscape model with hills, and by comparing the results with corresponding data obtained over a flat terrain model.

5. 3. iWHAM-integrated water, health and agriculture management : public health implications of integrated watershed management in a tribal area

   Author : Sandeep Nerkar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : agriculture;

   Abstract : Background: Water scarcity remains a major hurdle in the overall development of tribal people living on hilly terrain, and it is one of the major reasons for their various health problems. Integrated watershed management (IWM) aims to increase water availability and to enhance socio-economic development in such areas. READ MORE

6. 4. On Optimal Mission Planning for Vehicles over Long-distance Trips

   Author : Ahad Hamednia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic dynamic programming; Optimal control; Logistics planning; Thermal and charging management; Model predictive control; Mission planning;

   Abstract : This thesis proposes a mission planner for vehicles over long-distance trips, for finding the optimal trade-off between trip time, energy efficiency, and driver comfort, subject to road information, traffic situations, and weather conditions. The mission planner consists of three components, i.e. READ MORE

7. 5. Space-Time Algorithms for Mobile Communications

   Author : Per Pelin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna array; model order selection; equalization; Bootstrap; space-time propagation; synchronization; RAKE-combiner; real data; data reduction; spatial diversity; finite alphabet;

   Abstract : Algorithms are presented for space-time signal processing in mobile communication systems employing base station antenna arrays. Two main issues are concerned. Reception of data transmitted on the uplink (mobile to base station transmission), and estimation of the parameters of the space-time mobile channel. READ MORE
