2. 1. Digital Content Networks : The Past, the Present and Decentralizing

   Author : Tommo Reti; Marko Turpeinen; Nils Enlund; Jussi Kangasharju; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : This thesis presents a solution-oriented analysis of current issues in digital content distribution management and content networks. The findings support the view that the recent development in the area has created a few congestion points, both in content distribution and content business, that gather increasing technical, social, financial, and political influence in the world.

4. 2. Digital Dispersion Equalization and Carrier Phase Estimation in 112-Gbit/s Coherent Optical Fiber Transmission System

   Author : Tianhua Xu; Sergei Popov; Gunnar Jacobsen; Jie Li; Magnus Karlsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherent transmission; chromatic dispersion; carrier phase estimation; digital signal processing; Optics; Optik; Photonics; Fotonik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Coherent detection employing multilevel modulation format has become one of the most promising technologies for next generation high speed transmission system due to the high power and spectral efficiencies. With the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.

5. 3. Designs for Learning in an Extended Digital Environment : Case Studies of Social Interaction in the Social Science Classroom

   Author : Susanne Kjällander; Staffan Selander; Eva Svärdemo Åberg; Ria Heilä-Ylikallio; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interaction; learning; meaning-making; digital learning resources; Social Science; school; classroom; pupils; teachers; didactic design; digital interface; assessment; designs for learning; multimodality; Education; Pedagogik; Didactics; didaktik;

   Abstract : This thesis studies designs for learning in the extended digital interface in the Social Science classroom. The aim is to describe and analyse how pupils interact, make meaning and learn while deploying digital learning resources. Together with the thesis a multimodal design theoretical perspective on learning has developed: Designs for Learning. READ MORE

6. 4. Mobile Supported e-Government Systems : Analysis of the Education Management Information System (EMIS) in Tanzania

   Author : Gudrun Wicander; John-Sören Pettersson; Anders G. Nilsson; Peter Rönnlund; Louise Yngström; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; e-Government systems; mobile telephony; SMS; blended digital system; education management; information systems; systems theory; developing countries; Tanzania; ICT4D; M4D; Information Systems; Informatik;

   Abstract : e-Government systems are considered by both governments and international organisations to improve administration and management. In Tanzania, an e-government system for education administration, EMIS, is partly implemented but shows several limitations. READ MORE

7. 5. Time resolved digital holographic interferometry through disturbed phase objects

   Author : Henrik Lycksam; Pierre Slangen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

   Abstract : Digital holographic interferometry is an optical measurement technique based on the work by Powell and Stetson in 1965. The basic principle of the method is that the whole light wave (both amplitude and phase) from an opaque surface or transparent object can be captured and stored using a single camera. READ MORE
