1. 1. Efficient hull design for ice conditions in inland waterways

   Författare :Meng Zhang; Karl Garme; Magnus Burman; Pentti Kujala; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inland waterway ship; ice conditions; ice properties; ice-hull interaction; ice resistance; impact load; numerical method; operation time window; lightweight design; composites and sandwich structure; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. Usually, IWW ships are designed without ice operation concerns and are structurally weaker than ships designed according to ice-class notifications from the classification societies. LÄS MER

5. 4. Cooling demand in commercial buildings-The influence of building design

   Författare :Hendrik Voll; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar factor; influence of design; cooling load; Commercial buildings; energy need; window share;

   Sammanfattning : Large window areas and glass façades have become popular by architects. As the glass architecture has become fashionable in quite a short time it seems that the architects are not always aware of the energy consuming consequences that the highly glazed buildings, sometimes in combination with special room plans might cause.

7. 5. Big Data Analytics for Fault Detection and its Application in Maintenance

   Författare :Liangwei Zhang; Ramin Karim; Janet Lin; Benoît Iung; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Big Data analytics; eMaintenance; fault detection; high-dimensional data; stream data mining; nonlinear data; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : Big Data analytics has attracted intense interest recently for its attempt to extract information, knowledge and wisdom from Big Data. In industry, with the development of sensor technology and Information & Communication Technologies (ICT), reams of high-dimensional, streaming, and nonlinear data are being collected and curated to support decision-making.
