1. 11. Water and Heat Transport in Road Structures : Development of Mechanistic Models

   Författare :Klas Hansson; Lars-Christer Lundin; Kurt Roth; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Water flow; Heat flow; Unsaturated flow; Freeze-thaw; Numerical models; Uncertainty analysis; Sensitivity analysis; Roads; Overland flow; Flow patterns; TDR; Water content reflectometer; Calibration; Fractures; Hydrologi; Hydrology; Hydrologi;

   Sammanfattning : The coupled transport of water and heat, involving freezing and thawing, in the road structure and its immediate environment is important to consider for optimal design and maintenance of roads and when assessing solute transport, of e.g. de-icing salt, from roads. LÄS MER

3. 12. Open Source Vendors’ Business Models

   Författare :Thomas Rosenfall; Anna Öhrwall Rönnbäck; Staffan Brege; Mogens Kühn Pedersen; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Open Source Software; Business Models; Open Source Business Models; Open Source Communities; Software Licensing;

   Sammanfattning : It may seem controversial that open-source software (OSS), i.e. software created by voluntary contributions that is available to use, change, and distribute for free, can be utilized for business purposes. Yet, for some firms, commercial OSS software products are the primary source of revenue. LÄS MER

4. 13. Information Management for Cutting Tools : Information Models and Ontologies

   Författare :Olof Nyqvist; Torsten Kjellberg; Fumihiko Kimura; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Production Engineering; Cutting Tools; Information Models; International Standards; Reference Data; Ontologies; Information technology; Informationsteknologi;

   Sammanfattning : There is an increasing demand for the exchange of important product and manufacturing information in a computer interpretable way. Large manufacturing companies are dependent on having access to the necessary information electronically. LÄS MER

5. 14. Collaboration and Coordination Challenges in Patient-Centered Care : Models and Informaion Services

   Författare :Monica Winge; Benkt Wangler; Paul Johannesson; Fredrik Karlsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; patient-centered care; healthcare; social care; home care; collaboration; coordination; care processes; processes coordination; multi-sectoral collaboration; communication; information models; information services; management; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : This thesis reports on research focuses on how to deal with the fact that the organization and processesof today’s health and social care are becoming ever more complex as a consequence of societal trends, including an aging population and an increased reliance on care at home. The overall research goal is to suggest ways in which IT-based solutions can enable and leverage collaboration and coordination insituations where a co-morbid patient is subject to care delivered simultaneously by several different professionals and organizations.

7. 15. Multiple-Input Multiple-Output Radio Propagation Channels : Characteristics and Models

   Författare :Kai Yu; Björn Ottersten; David Gesbert; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; Signal processing; Signalbehandling;

   Sammanfattning : In recent years, deploying multiple antennas at both transmitter and receiver has appeared as a very promising technology. By exploiting the spatial domain, multiple-input multiple-output (MIMO) systems can support extremely high data rates as long as the environments can provide sufficiently rich scattering. LÄS MER
