1. 1. Självhjälp och överlevnad : en studie av Länkarna

   Författare :Noriko Kurube; Klaus Mäkelä; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; socialt arbete; Social Work;

   Sammanfattning : This study has been carried out as part of a Swedish investigation within the framework of an international project on the AA movement, The International Collaborative Study of Alcoholics Anonymous (ICSAA). The purpose of the study has been to describe and analyse the Link movement in terms of its character and development as a self-help movement by and for persons with alcohol problems. LÄS MER

3. 2. Mobility and Multi-channel Communications in Low-power Wireless Networks

   Författare :António Gonga; Mikael Johansson; Riku Jäntti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Multi-channel communications; Neighbor Discovery; MAC Protocols; Low-power Wireless Networks; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The prospect of replacing existing fixed networks with cheap, flexible and evenmobile low-power wireless network has been a strong research driver in recent years.However, many challenges still exist: reliability is hampered by unstable and burstycommunication links; the wireless medium is getting congested by an increasingnumber of wireless devices; and life-times are limited due to difficulties in developingefficient duty-cycling mechanisms.

4. 3. Finding, extracting and exploiting structure in text and hypertext

   Författare :Ola Ågren; Jürgen Börstler; Frank Drewes; Maarten de Rijke; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automatic propagation; CHiC; Data mining; Discrete data; Extraction; Hierarchies; ProT; Rank distribution; S²ProT; Spatial linking; Web mining; Web searching; Computer science; Datalogi; business data processing; administrativ databehandling;

   Sammanfattning : Data mining is a fast-developing field of study, using computations to either predict or describe large amounts of data. The increase in data produced each year goes hand in hand with this, requiring algorithms that are more and more efficient in order to find interesting information within a given time. LÄS MER

5. 4. The global energy system through a prism of change : The oil & gas industry and the case of the Arctic

   Författare :Maria Morgunova; Vladimir Kutcherov; Pär Blomkvist; Stefan Andreasson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; global energy system; energy industry; oil gas industry; Arctic offshore; change; transformation; sustainable energy transition; industrial dynamics; multi-level perspective; development blocks; globalt energisystem; energibranschen; olje- och gasindustrin; Arctic offshore; förändring; omvandling; hållbar energiövergång; industriell dynamik; flernivå perspektiv; utvecklingsblock; Industriell ekonomi och organisation; Industrial Economics and Management;

   Sammanfattning : The energy industry as a whole and the oil & gas industry in particular is experiencing changes under the influence of a variety of trends and the changing needs of society. Current social, economic, environmental and climate challenges are raising sharp questions for the established principles of energy production and consumption, increasingly arguing for sustainable trajectories in the development of the global energy system.
