1. 11. Performance Indicators. A performance prediction method for moisture safety design

   Författare :Veronica Yverås; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial Neural Network; Performance prediction; Moisture safety;

   Sammanfattning : The aims of this research project is to develop and gain knowledge about a different approach to moisture safety design based on AI in order to attain healthy buildings and relate this new approach to current practice and prospective users. Secondary data (data produced for some other purpose) was used to train Artificial Neural Networks (ANN) to predict the performance of outdoor ventilated crawl-spaces regarding microbiological smell, mould and rot.

3. 12. 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.

   Sammanfattning : IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. LÄS MER

7. 15. On Radio Wave Propagation Measurements and Modelling for Cellular Mobile Radio Networks

   Författare :Erik Östlin; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Field strength measurements; path loss prediction; point-to-area; Recommendation ITU-R P.1546; artificial neural network; large- and small-scale fading characteristics;

   Sammanfattning : To support the continuously increasing number of mobile telephone users around the world, mobile communication systems have become more advanced and sophisticated in their designs. As a result of the great success with the second generation mobile radio networks, deployment of the third and development of fourth generations, the demand for higher data rates to support available services, such as internet connection, video telephony and personal navigation systems, is ever growing.
