2. 21. Sampling and Analysis of Tars by Means of Photo Ionization Detection and Solid Phase Micro Extraction

   Author : Mozhgan Ahmadi Svensson; Klas Engvall; Wiebren de Jong; KTH; []
   Keywords : ;

   Abstract : Gasification of biomass will likely play an important role in the production of energy and chemicals in a future sustainable society. However, during gasification impurities, such as tars, will be formed. Tars may cause fouling and blockages of equipment downstream the gasifier. READ MORE

4. 22. Measurements and analysis of electromagnetic interferences in the Swedish railway systems

   Author : Stefan Niska; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Presently, the existing failure reporting system at Banverket (the Swedish Rail Administration), which handles reports on the failures of the railway infrastructures and possible causes of failure, is not optimum (or most suitable) when it comes to analysis of electromagnetic compatibility (EMC)- related failures and causes. This failure reporting system is reliant on correct reporting into the system, so that the right information can be sent back to the users, the maintenance and service personnel, in real time.

5. 23. Artificial Intelligence-Based Characterization and Classification Methods for Power Quality Data Analytics

   Author : Azam Bagheri; Math Bollen; Surya Santoso; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power System; power Quality; Voltage Dip; Big Data; Deep Learning; Machine Learning; Active Learning; Consensus Contriol; Electric Power Engineering; Elkraftteknik;

   Abstract : One of the important developments in the electric power system is the fast increasing amount of data. An example of such data is formed by the voltages and currents coming from power-quality measurements. READ MORE

6. 24. Energy-efficient cloud computing : autonomic resource provisioning for datacenters

   Author : Selome Kostentinos Tesfatsion; Johan Tordsson; Eddie Wadbro; Erik Elmroth; Laurent Lefevre; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud computing; datacenter; energy-efficiency; performance management; virtualization;

   Abstract : Energy efficiency has become an increasingly important concern in data centers because of issues associated with energy consumption, such as capital costs, operating expenses, and environmental impact. While energy loss due to suboptimal use of facilities and non-IT equipment has largely been reduced through the use of best-practice technologies, addressing energy wastage in IT equipment still requires the design and implementation of energy-aware resource management systems.

7. 25. Extracting Information from Voltage-Dip Monitoring

   Author : Azam Bagheri; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

   Abstract : A voltage dip is a short duration reduction in voltage magnitude due to a short duration increase in current magnitude. Causes of dips are, among others, electrical faults, large motor starting, transformer energizing and failure of power-electronic converters. READ MORE
