1. 21. Non-Energy Benefits of Industrial Energy Efficiency : Roles and Potentials

   Författare :Therese Nehler; Patrik Thollander; Mats Söderström; Erik Dahlquist; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Climate and environmental targets place significant requirements on energy efficiency and improved industrial energy efficiency is viewed as one of the most important means of reducing CO2 emissions and mitigating climate change. Even though efforts have been undertaken to improve energy efficiency there is still the potential for further improvements to be made. LÄS MER

3. 22. Planning production and supply chain in energy intensive process industries

   Författare :Martin Waldemarsson; Helene Lidestam; Martin Rudberg; Magnus Karlsson; Sophie D'Amours; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Energy-intensive production processes; Energy system; Energy management; Production planning; Supply chain planning; Case studies; Mixed Integer Linear Programming; Modelling; Specialty chemicals; Pulp; Steel;

   Sammanfattning : To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users.

4. 23. Evaluating as designing. Towards a Balanced IT investements Approach

   Författare :Elisabeth Frisk; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IS evaluation; IT investments; design attitude; collaborative practice research;

   Sammanfattning : The evaluation of information technology (IT) investments continues to present challenges to many organizations. While the emergence of new technologies complicates this activity, business value from IT typically resides with both tangible and intangible aspects. LÄS MER

5. 24. Tar and Condensable Hydrocarbons in Indirect Gasification Systems

   Författare :Mikael Israelsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UCS; Tar; condensable species; DFB; HTR.; CS; CLR; SPA;

   Sammanfattning : Biomass gasification, which is a primary process step in the production of biofuels, yields a combustible gas mixture (raw gas). This raw gas consists of a wide range of species, from permanent gases to condensable hydrocarbons, which are collectively known as tar. LÄS MER

7. 25. Community-based customer involvement for improving packaged software development

   Författare :Helena Holmström; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Packaged software development; software improvement; virtual communities; customer involvement; community knowledge; community-based customer involvement;

   Sammanfattning : Noting the widespread use of virtual communities for interacting with customers, this thesis explores the role of virtual communities for involving distributed customers in packaged software development (psd) and the opportunities and challenges that are associated with this. While the idea of involving customers in software development is not new, it is yet to gain momentum in psd. LÄS MER
