1. 1. Estimating Human Limb Motion Using Skin Texture and Particle Filtering

   Författare :Björn Holmberg; Håkan Lanshammar; Virgil Stokes; Christopher L. Vaughan; Uppsala universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

   Sammanfattning :    Information systems (IS) are widely acknowledged to be central for contemporary organizations. Along with the increasing importance of new IS in organizations, a school of thought has developed over the last few years that claims that IS and organizations mutually shape each other. LÄS MER

5. 4. Statistical Inference of Information in Networks : Causality and Directed Information Graphs

   Författare :Sina Molavipour; Mikael Skoglund; Deniz Gündüz; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Over the last decades, the advancements in measurement, collection, and storage of data have provided tremendous amounts of information. Thus, it has become crucial to extract valuable features and analyze the characteristics of data. As we study more complex systems (e.g. LÄS MER

7. 5. A time and place for everything? : social visualisation tools and critical literacies

   Författare :Veronica Johansson; Högskolan i Borås; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Critical literacy; Document perspective; enactments of meaning; geographic information systems GIS ; ICT; information activities; inscriptions; interaction; library and information science LIS ; representation; social data; social visualisation tools; sociocultural perspective; Library and information science; Library and Information Science; Biblioteks- och informationsvetenskap;

   Sammanfattning : The aim of this study is to analyse mutual enactments of critical literacies and social visualisation tools as information resources. The central concept of critical literacies as used here extends and redefines prior critical literacy definitions to denote the pluralistic situated enactments of meaning through which study participants identify, question and transform bias, restrictions and power related aspects of access, control and use in relation to the tools.
