1. 6. Support for the conceptual design stage of effective and resource-efficient offerings : A pragmatic and cross-disciplinary approach

   Författare :Sergio Brambila; Tomohiko Sakao; Anne-Marie Tillman; Vicky Lofthouse; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; cross-disciplinary; designing; efficient; effective; lifecycle; support;

   Sammanfattning : Human activities in the form of production and consumption have increased to an all-time high. In many cases, this increase has resulted in environmental problems such as waste and pollution that, in turn, affect our health and way of living. Societies have proposed different measures to address such environmental problems. LÄS MER

3. 7. Energy Efficient Protocols for Active RFID

   Författare :Björn Nilsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wake-up radio; energy consumption; energy efficient; Active RFID; protocol; RFID; throughput; back-off; RFID-system; delay;

   Sammanfattning : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. LÄS MER

4. 8. Virtual and Physical Methods for Efficient Ergonomics Risk Assessments - A Development Process for Application in Car Manufacturing

   Författare :Ann-Christine Falck; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; car manufacturing; holistic; efficient; virtual; ergonomics; methods; physical; risk assessment;

   Sammanfattning : Work-related disorders and sick leave are well-known common problems in the manufacturing industry. Workrelateddisorders cost both society and the manufacturing industry huge amounts of money every year as aconsequence of poor working environment and assembly-unfriendly products. LÄS MER

5. 9. Equine glutathione transferase A3-3 : an efficient steroid isomerase

   Författare :Helena Lindström; Bengt Mannervik; Ann-Kristin Östlund Farrants; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Equine; glutatione transferase; steroidogenesis; steroid isomerase; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication by making toxic electrophiles more polar and therefore more easily excretable. However some GSTs have developed alternative functions. LÄS MER

7. 10. Fuel-efficient driving strategies

   Författare :Sina Torabi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed profile optimization; fuel efficiency; neural networks.; energy efficiency; genetic algorithms; performance analysis; road grade estimation; mass estimation; vehicle platooning;

   Sammanfattning : This thesis is concerned with fuel-efficient driving strategies for vehicles driving on roads with varying topography, as well as estimation of road grade and vehicle mass for vehicles utilizing such strategies. A framework referred to as speed profile optimization (SPO), is introduced for reducing the fuel or energy consumption of single vehicles (equipped with either combustion or electric engines) and platoons of several vehicles.
