1. 11. Development of speed-power performance models for ship voyage optimization

   Författare :Xiao Lang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale measurements; speed-power performance; added resistance due to waves; energy efficiency; machine learning; voyage optimization;

   Sammanfattning : Various measures, such as voyage optimization, performance monitoring and ship cleaning schedules, have been developed to help increase the energy efficiency of shipping operations. One of the most important elements needed for these measures is a reliable ship speed-power model. LÄS MER

3. 12. Lower limb venous incompetence and the effect of radiofrequency ablation versus open surgery : Focus on haemodynamics, quality of life and health economic aspects

   Författare :Oskar Nelzén; Helene Zachrisson; Toste Länne; Johan Skoog; Gunnar Plate; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic venous incompetence; Varicose veins; Radiofrequency ablation; High ligation stripping Duplex ultrasound; Strain-gauge plethysmography; Quality of Life; Health economic evaluation;

   Sammanfattning : Chronic venous incompetence (CVI) is a common condition, and varicose vein treatment is one of the most-common surgical procedures performed worldwide. Common symptoms of CVI are pain, cramps, itching, feeling of leg heaviness and venous claudication. Advanced CVI can lead to skin changes, eczema and venous ulcers. LÄS MER

4. 13. The Influence of Energy Levels on Voltage Losses and Charge Generation in Organic Solar Cells

   Författare :Jianwei Yu; Feng Gao; Olle Inganäs; Niclas Solin; Christoph J. Brabec; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Organic solar cells (OSCs) are a next-generation photovoltaic technology that convert solar energy to electrical energy. They have attracted great attention due to their advantages of low cost, ease of synthesis, light weight, mechanical flexibility, and roll-to-roll processability. LÄS MER

5. 14. Inter-team Coordination in Large-Scale Agile Software Development Projects

   Författare :Tomas Gustavsson; John Sören Pettersson; Linda Bergkvist; Marie-Therese Christiansson; Pär Ågerfalk; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inter-Team Coordination; Large-Scale Agile Software Development; Institutional logics; Scaled Agile Framework; Project Management; Information Systems; Informatik;

   Sammanfattning : Software development organizations worldwide are adopting values, principles, and frameworks to implement Agile ways of working. The advantages of Agile ways of working are seen in teams that are allowed a high level of autonomy. LÄS MER

7. 15. Nonionic surfactants : A multivariate study

   Författare :Lise-Lott Uppgård; Michael Sjöström; Svante Wold; Jiri Damborsky; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AEO; APG; aquatic toxicity; cellulose reactivity; Fock; MLR; multivariate data analysis; nonionic surfactant; PCA; physicochemical properties; PLS; QSAR; surface activity; viscose; Chemistry; Kemi;

   Sammanfattning : In this thesis technical nonionic surfactants are studied using multivariate techniques. The surfactants studied were alkyl ethoxylates (AEOs) and alkyl polyglucosides (APGs). The aquatic toxicity of the surfactants towards two organisms, a shrimp and a rotifer, was examined. The specified effect was lethality, LC50, as indicated by immobilisation. LÄS MER
