2. 21. On System Safety and Reliability Methods in Early Design Phases : Cost Fo cused Optimization Applied on Aircraft Systems

   Author : Cristina Johansson; Johan Ölvander; Per Persson; Linköpings universitet; []
   Keywords : ;

   Abstract : System Safety and Reliability are fundamental to system design and involve a quantitative assessment prior to system development. An accurate prediction of reliability and system safety in a new product before it is manufactured and marketed is necessary as it allows us to forecast accurately the support costs, warranty costs, spare parts requirements, etc. READ MORE

5. 23. On direct hydrogen fuel cell vehicles : modelling and demonstration

   Author : Kristina Haraldsson; Per Alvfors; Dougal J. Nelson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; direct hydrogen; Proton Exchange Membrane; PEM; fuel cell; fuel cell vehicle; fuel cell hybrid vehicles; on-board hydrogen storage; Kemiteknik; Chemical engineering; Kemiteknik;

   Abstract : In this thesis, direct hydrogen Proton Exchange Membrane (PEM) fuel cell systems in vehicles are investigated through modelling, field tests and public acceptance surveys. A computer model of a 50 kW PEM fuel cell system was developed. The fuel cell system efficiency is approximately 50% between 10 and 45% of the rated power. READ MORE

6. 24. Improving the Adaptability of the End-host : Service-aware Network Stack Tuning

   Author : Alexander Rabitsch; Anna Brunström; Per Hurtig; Stefan Alfredsson; Michael Welzl; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; transport layer; 5G; transport services; mobile broadband; network slicing; latency; availability; service optimization; multi-connectivity; Computer Science; Datavetenskap;

   Abstract : The Internet of today is very different from how it used to be. Modern networked applications are becoming increasingly diverse. Consequently, a variety of requirements must be met by the network. Efforts to make the underlying mechanisms of the Internet more flexible have therefore been made to adapt to this diversification.

7. 25. Deep learning on large neuroimaging datasets

   Author : Johan Jönemo; Anders Eklund; Ida Häggström; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Magnetic resonance imaging (MRI) is a medical imaging method that has become increasingly more important during the last 4 decades. This is partly because it allows us to acquire a 3D-representation of a part of the body without exposing patients to ionizing radiation. READ MORE
