   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thrust estimation; Kalman filtering; Gas turbine performance estimation; Reduced order observers; Gas path analysis;

   Abstract : An advanced turbofan engine control system would benefit from an accurate thrust and engine performance estimate. Unfortunately, there is to date no reliable in-flight thrust measurement sensors available. READ MORE

4. 2. Practice makes perfect? : Sustainable practices with ICT and daily travel

   Author : Miriam Börjesson Rivera; Mattias Höjer; Greger Henriksson; Josefin Wangel; Jenny Palm; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social practice theory; sustainable practices; ICT; mobility; second order effects; cargo bikes; mediated meetings; Planering och beslutsanalys; Planning and Decision Analysis;

   Abstract : The thesis shows how practice theory can be applied in different ways when exploring how daily life can be supported to become more environmentally sustainable. Ultimately the thesis aims to contribute to new knowledge on how to design policies and interventions that aim at facilitating environmentally sustainable practices. READ MORE

5. 3. What is a sustainable everyday life? : Exploring and assessing the sustainability of everyday travel, sharing and ICT

   Author : Miriam Börjesson Rivera; Greger Henriksson; Mattias Höjer; Josefin Wangel; Jillian Anable; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Planering och beslutsanalys; Planning and Decision Analysis;

   Abstract : In a world where the general trend is unsustainable consumption patterns, can sustainable everyday life be enabled? This thesis sought to expand the knowledge base for policies and measures for sustainability, based on the assumption that consumption can be viewed as the outcome of practices in which people engage in their day-to-day life. The thesis addressed the overall aim by examining the following questions: How can information and communication technology (ICT) practices contribute to sustainable everyday practices? How can sharing practices, ICT-based and other, contribute to sustainable everyday practices? and How can travel practices, ICT-based and other, contribute to sustainable everyday practices?Empirical and conceptual studies revealed that ICT has become a fundamental and integral part of everyday practices and that digitalisation is a tangible material companion with implications for sustainability.

6. 4. Diagnosis and Supervision of Industrial Gas Turbines

   Author : Emil Larsson; Jan Åslund; Erik Frisk; Lars Eriksson; Mattias Henriksson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Monitoring of industrial gas turbines is of vital importance, since it gives valuable information for the customer about maintenance, performance, and process health. The performance of an industrial gas turbine degrades gradually due to factors such as environment air pollution, fuel content, and ageing to mention some of the degradation factors. READ MORE

7. 5. Adverse Muscle Composition : Revisiting Sarcopenia in General Population and Liver Disease using Magnetic Resonance Imaging

   Author : Jennifer Linge; Mattias Ekstedt; Patrik Nasr; Martin Henriksson; Tommy Cederholm; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Sarcopenia - from the Greek words 'sarx' (flesh) and 'penia' (loss) - was, when coined in 1989, a term denoting the decline in muscle mass and strength that occurs with aging. Such definition implies everyone suffers from sarcopenia to varying degrees, which naturally makes studying sarcopenia challenging. READ MORE
