   Sammanfattning : Social networking sites are integral in reshaping how we access and interact with information and others. This doctoral thesis aims to offer an in-depth understanding of engagement in an everyday life information practice within a private Facebook group. LÄS MER

3. 2. Development of IT-supported Inter-organisational Collaboration : A Case Study in the Swedish Public Sector

   Författare :Anneli Hagdahl; Toomas Timpka; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information technology; Public sector; interorganizational relations; Interorganizational relations; labour market; Information technology; Informationsteknologi;

   Sammanfattning : Collaboration across the organisational boundaries takes place for different reasons. One of them is to solve complex problems that cannot be dealt with by a single organisation. The area of vocational rehabilitation constitutes an example of inter-organisational collaboration motivated by a need for joint problem solving. LÄS MER

4. 3. Estimating Human Limb Motion Using Skin Texture and Particle Filtering

   Författare :Björn Holmberg; Håkan Lanshammar; Virgil Stokes; Christopher L. Vaughan; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human motion analysis; Skin texture; Monte Carlo estimation; Particle filter; Mutual Information; Simulated Annealing; Marker-free; Rigid body transformation; 2D correlation; Systems engineering; Systemteknik;

   Sammanfattning : Estimating human motion is the topic of this thesis. We are interested in accurately estimating the motion of a human body using only video images capturing the subject in motion. Video images from up to two cameras are considered.The first main topic of the thesis is to investigate a new type of input data. LÄS MER

5. 4. Coordinated MultiPoint Transmission with Incomplete Information

   Sammanfattning : 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. LÄS MER

7. 5. Joint control in dynamic situations

   Författare :Björn Johansson; Erik Hollnagel; Berntd Brehmer; Yvonne Waern; Janine Rogalski; Linköpings universitet; []
