2. 11. Data analytics for weak spot detection in power distribution grids

   Author : Hassan Mashad Nemati; Sławomir Nowaczyk; Anita Pinheiro Sant'Anna; Math Bollen; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This research aims to develop data-driven methods that extract information from the available data in distribution grids for detecting weak spots, including the components with degraded reliability and areas with power quality problems. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from available data. READ MORE

4. 12. Architecture Support and Scalability Analysis of Memory Consistency Models in Network-on-Chip based Systems

   Author : Abdul Naeem; Axel Jantsch; Zhonghai Lu; Jari Nurmi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory consistency; Protected release consistency; Distributed shared memory; Network-on-Chip; Scalability;

   Abstract : The shared memory systems should support parallelization at the computation (multi-core), communication (Network-on-Chip, NoC) and memory architecture levels to exploit the potential performance benefits. These parallel systems supporting shared memory abstraction both in the general purpose and application specific domains are confronting the critical issue of memory consistency. READ MORE

5. 13. Life satisfaction in late life: Markers and predictors of level and change among 80+ year olds

   Author : Anne Ingeborg Berg; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Life satisfaction; oldest-old; longitudinal design; health; social network; locus of control; depressive symptoms; personality;

   Abstract : The overall aim of the thesis was to examine within-individual and between-individual changes in life satisfaction in the oldest-old using different time metrics and to study life satisfaction within the context of psychosocial and health-related variables. Data were obtained from the Swedish OCTO-Twin Study of individuals aged 80 and older who were able to complete the Life Satisfaction Index-Z (LSI-Z). READ MORE

6. 14. Applications of natural organic matter optical properties for assessing drinking water disinfection and distribution

   Author : Masoumeh Heibati; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; assimilable organic carbon.; Optical properties; disinfection by-products; drinking water; UV disinfection; dissolved organic matter; distribution network;

   Abstract : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants a nd within distribution networks. READ MORE

7. 15. Fault Behavior of Wind Turbines

   Author : Francesco Sulla; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Turbines; Short-Circuit Currents; Doubly-Fed Induction Generator; Grid Fault Ride-Through; Voltage Support; Weak Grid;

   Abstract : Synchronous generators have always been the dominant generation type in the grid. This fact affected both planning and operation of power systems. With the fast increase of wind power share in the grid in the last decade, the situation is changing. In some countries wind power represents already a consistent amount of the total generation.
