1. 1. Residential Demand Response in the Context of European Union Energy Policy

   Författare :Pia Stoll; Fredrik Gröndahl; Nils Brandt; Lars Nordström; Will Kling; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Ecology; Industriell ekologi;

   Sammanfattning : In order to achieve energy security, reduce global warming and promote the vision of a common electricity market, the European Union (EU) is transforming the EU electricity grid from a large set of independent hierarchical national grids into one meshed EU-wide grid. For the first time in the history of the electric power industry, residential consumers are being integrated into the grid as active consumers and micro-generators of electricity. LÄS MER

3. 2. Toward Privacy-Preserving Decentralised Systems

   Författare :Guillermo Rodríguez-Cano; Sonja Buchegger; Johan Boye; Matteo Magnani; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decentralised information systems; distributed systems; privacy; social networks; decentraliserade informationssystem; distribuerade system; integritet; sociala nätverk; sistemas de información descentralizados; sistemas distribuidos; privacidad; redes sociales; Computer Science; Datalogi;

   Sammanfattning : Privacy enhancing technologies have proven to be a beneficial area of research lessening the threats users' privacy in centralised systems such as online social networks. Decentralised solutions have been proposed to extend the control that users have over their data as opposed to the centralised massive collection of personal and sensitive data. LÄS MER

5. 4. Om vikten av att i automationsprocessen integrera handens och hjärnans arbete

   Författare :Bertil Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tacit knowledge; Small scale production; Operator´s computer; Cross-functional work teams; Robot arc welding; Decentralised work organisation;

   Sammanfattning : This licentiate report attempts to add to our knowledge of how the competence of skilled workers can be incorporated into modern manufacturing systems, without depriving them of the status that they had earned through their previous specialised skills and knowledge. The work is concentrated on establishing a theoretical basis for a model of how the computer can support this work: the Operator's Computer approach has been applied in three case-studies, thus taking it over the threshold into the Swedish engineering industry.
