1. 21. Aging effects on commercial lean NOx trap catalysts

   Författare :Jesus De Abreu Goes; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging; thermal degradation; sulfur poisoning; characterization; commercial lean NOx traps; NOx storage and reduction;

   Sammanfattning : As a countermeasure to global warming, vehicles with low carbon emissions are being investigated by promoting lean-burn engines and high combustion efficiencies. However, one limitation to the increasing use of these engines is the need to develop corresponding catalytic systems for controlling the nitrogen oxide (NOx) emissions in their lean exhaust.

3. 22. Unfolding Evolutionary Growth Within a Subsidiary: The Case of a Sales Subsidiary in the Middle East

   Författare :Johan Jakobsson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Evolutionary Growth; Capabilities; Multinational Corporation; Resource Management; Subsidiary; Subsidiary Charter; Subsidiary Evolution;

   Sammanfattning : Subsidiaries are important entities in multinational corporations and are typically established with predetermined business responsibilities. A subsidiary responds to actors in the internal network (e.g. , HQs and other subsidiaries) as well as actors in the external network (e. LÄS MER

4. 23. Jet lag and shiftwork : their effects on sleep & sleepiness

   Författare :Arne Lowden; Ulf Landström; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sleep; alertness; jet lag; activity; EEG; shift work; psykologi; Psychology;

   Sammanfattning : The aim of the studies was to describe the detailed sleep/wake patterns before, during, and after a period of work that forces individuals to deviate from their normal sleep/wake pattern. Possible countermeasures to experienced problems was evaluated in intervention designs. LÄS MER

5. 24. A System-Level Framework for Energy and Performance Estimation in System-on-Chip Architectures

   Författare :Sandro Penolazzi; Ahmed Hemani; Anshul Kumar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer engineering; Datorteknik; Electronics; Elektronik;

   Sammanfattning : Shifting the design entry point up to the system level is the most important countermeasure adopted to manage the increasing complexity of SoCs. The reason is that decisions taken at this level, early in the design cycle, have the greatest impact on the final design in terms of performance, energy efficiency and silicon area occupation.

7. 25. Situation analysis for fighter aircraft combat survivability

   Författare :Tina Erlandsson; Lars Niklasson; Göran Falkman; Silvia Coradeschi; Per-Johan Nordlund; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fighter aircraft; situation analysis; combat survival; decision support; uncertainty; Datalogi; Computer and Systems Science; Teknik;

   Sammanfattning : Fighter pilots operate in environments where an erroneous decision may have fatal consequences. A tactical decision support system (TDSS) could aid the pilots to analyze the situation and make correct decisions. The TDSS can, for instance, highlight important information and suggest suitable actions. LÄS MER
