1. 11. On Statistical Methods for Safety Validation of Automated Vehicles

   Författare :Daniel Åsljung; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; performance evaluation; extreme value theory; Automotive; validation; automated vehicles; simulation; verification; automated driving systems;

   Sammanfattning : Automated vehicles (AVs) are expected to bring safer and more convenient transport in the future. Consequently, before introducing AVs at scale to the general public, the required levels of safety should be shown with evidence. However, statistical evidence generated by brute force testing using safety drivers in real traffic does not scale well. LÄS MER

3. 12. Förhållningssätt och kommunikation i mötet med personer med demenssjukdom : utvärdering av ett träningsprogram med validationsmetoden

   Författare :Mona Söderlund; Görel Hansebo; Astrid Norberg; Britt-Marie Ternestedt; Agneta Cronqvist; Helle Wijk; Ersta Sköndal högskola; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Validation method; Evaluation studies; Dementia care; Communication skills; Caring approach; Videotaped conversations; Qualitative analyses; validation method;

   Sammanfattning : Communication difficulties among residents with dementia disease living in nursing homes may complicate care situations. These residents can have difficulties describing how they experience their everyday lives, which can lead to withdrawal, social isolation, or feelings of homelessness. LÄS MER

4. 13. Highway Traffic State Estimation and Short-term Prediction

   Författare :Andreas Allström; Jan Lundgren; Clas Rydergren; Balázs Adam Kulcsár; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : Traffic congestion is increasing in almost all large cities, leading to a number of negative effects such as pollution and delays. However, building new roads is not a feasible solution. Instead, the use of the existing road network has to be optimized, together with a shift towards more sustainable transport modes. LÄS MER

5. 14. On the dynamics of self-esteem : Empirical validation of Basic self-esteem and Earning self-esteem

   Författare :Maarit Johnson; Liisa Keltikangas-Järvinen; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Self-esteem; competence; validation; stability; adjustment; health; Psychology; Psykologi;

   Sammanfattning : The present thesis aims at distinguishing between self-esteem as basic self-love (basic self-esteem) and self-esteem as related to competence (earning self-esteem). In previous research these two phenomena have most often been studied under one and the same self-esteem concept. LÄS MER

7. 15. Saving Energy in Construction Machinery using Displacement Control Hydraulics : Concept Realization and Validation

   Författare :Kim Heybroek; Jan-Ove Palmberg; Jochen Pohl; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : In the sector of mobile hydraulics, valve controlled systems are predominant. In these systems the load force and speed are adjusted by control valves. In machines where multiple drives are used in parallel at extremely varying loads the energy efficiency of such systems is often compromised over large working regions. LÄS MER
