2. 1. Information Demand and Use : Improving Information Flow within Small-scale Business Contexts

   Author : Magnus Lundqvist; Kurt Sandkuhl; Sture Hägglund; Wolfgang Deiters; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Information Use; Information Demand; Information Logistics; Information Flow; Context; Patterns; Enterprise Modelling; Information Modelling; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Information technology; Informationsteknik;

   Abstract : Whilst the amount of information readily available to workers in information- and knowledge intensive business- and industrial contexts only seem to increase with every day, those workers still have difficulties in finding relevant and needed information as well as storing, distributing, and aggregating such information. Yet, whilst there exist numerous technical, organisational, and practical approaches to remedy the situation, the problems seem to prevail. READ MORE

4. 2. Making sense of spatial, sensor and temporal information for context modeling

   Author : Jose Antonio Monteagudo; Ramón David Jiménez; Dr. Marcelo Milrad; Mathias Hedenborg; Växjö universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mobile devices; temporal information; context; content; ubiquitous computing; sensor data; mobile web server; Information processing; Informationsbehandling; Computer science; Datavetenskap;

   Abstract : Context represents any information regarding the situation of entities, being these a person, place or object that is considered relevant to the interaction between a user and an application. The results obtained permits an user to save context information attached to a picture in a database, as well as retrieve pictures from that database and show it in a web interface with its context information associated.

5. 3. Efficient Temporal Reasoning with Uncertainty

   Author : Mikael Nilsson; Patrick Doherty; Jonas Kvarnström; Félix Ingrand; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Temporal Reasoning; Dynamic Controllability; Simple Temporal Network with Uncertainty; Incremental Algorithms; Temporal Networks;

   Abstract : Automated Planning is an active area within Artificial Intelligence. With the help of computers we can quickly find good plans in complicated problem domains, such as planning for search and rescue after a natural disaster. When planning in realistic domains the exact duration of an action generally cannot be predicted in advance. READ MORE

6. 4. Spatio-Temporal Pre-Processing Methods for Region-of-Interest Video Coding

   Author : Linda S. Karlsson; Tingting Zhang; Mårten Sjöström; Youzhi Xu; Apostolos Georgakis; Mittuniversitetet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Region-of-interest; video coding; pre-processing; spatio-temporal filters; Computer and systems science; Data- och systemvetenskap;

   Abstract : In video transmission at low bit rates the challenge is to compress the video with a minimal reduction of the percieved quality. The compression can be adapted to knowledge of which regions in the video sequence are of most interest to the viewer. READ MORE

7. 5. Topics in Dynamic Spectrum Access : Market Based Spectrum Sharing and Secondary User Access in Radar Bands

   Author : Miurel Tercero Vargas; Jens Zander; Mikael Prytz; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; spectrum sharing; radar band; cognitive radio; Telecommunication; Telekommunikation; Systems engineering; Systemteknik;

   Abstract : The steady growth in demand for spectrum has increased research interest in dynamic spectrum access schemes. This thesis studies some challenges in dynamic spectrum access based on two strategies: open sharing and hierarchical access. READ MORE
