1. 21. Load and Risk Based Maintenance Management of Wind Turbines

   Författare :Pramod Bangalore; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; wind energy.; supervisory control and data acquisition SCADA ; condition monitoring system CMS ; Artificial neural networks ANN ; maintenance strategy; maintenance planning; maintenance management; life cycle cost;

   Sammanfattning : The cost of maintenance is a considerable part of the total life cycle cost in wind turbines, especially for offshore applications. Research has shown that some critical components account for most of the downtime in the wind turbines. LÄS MER

3. 22. Load and risk based maintenance management of wind turbines

   Författare :Pramod Bangalore; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring system CMS ; optimization; supervisory control and data acquisition SCADA ; maintenance planning; Artificial neural network ANN ; life cycle cost; maintenance management; maintenance strategy; wind energy.;

   Sammanfattning : Wind power has proven to be an important source of renewable energy in the modern electric power systems. Low profit margins due to falling electricity prices and high maintenance costs, over the past few years, have led to a focus on research in the area of maintenance management of wind turbines.

4. 23. "Dom säger att jag ser mer normal ut med benproteser" : om samhällskrav kontra barns behov

   Författare :Karin Paulsson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Barn Habilitering Benproteser Sverige;

   Sammanfattning : The aim of this dissertation study is to explore what it meant to thirteen persons to grow up with severe limb deficiencies (due to Thalidomide) and under the extreme life-conditions that indirectly became the consequences of their impairments. Aspects discussed concern:- The functional, social and psychological value of artificial legs from early childhood to grown up age seen from the persons' own perspective. LÄS MER

5. 24. Efficient and Trustworthy Artificial Intelligence for Critical Robotic Systems

   Författare :Christopher Sprague; Petter Ögren; John Folkesson; Ivan Stenius; Todor Stoyanov; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; behaviour trees; hybrid dynamical systems; formal guarantees; optimal control; machine learning; autonomy; Datalogi; Computer Science;

   Sammanfattning : Critical robotic systems are systems whose functioning is critical to both ensuring the accomplishment of a given mission and preventing the endangerment of life and the surrounding environment. These critical aspects can be formally captured by convergence, in the sense that the system's state goes to a desired region of the statespace, and safety, in the sense that the system's state avoids unsafe regions of the statespace.

7. 25. Sensors and Algorithms in Industry 4.0 : Security and Health Preservation Applications

   Författare :Dawid Gradolewski; Wlodek Kulesza; Sven Johansson; Alberto Rodriguez-Martinez; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic Sensor; Artificial Intelligence; Autonomisation; Classification; Detection; Feature Extraction; Health Preservation; Identification; Internet of Things; Machine Learning; Multi-Sensor System; Safety System; Vision System; Systemteknik; Systems Engineering;

   Sammanfattning : Globalisation and technological digitisation have triggered an Industry 4.0. revolution.  The core of this revolution is autonomisation of complex processes, which require expert knowledge. LÄS MER
