   Sammanfattning : Deep learning, the study of multi-layered artificial neural networks, has received tremendous attention over the course of the last few years. Neural networks are now able to outperform humans in a growing variety of tasks and increasingly have an impact on our day-to-day lives. LÄS MER

4. 3. Hydraulic- hydromorphologic analysis as an aid for improving peak flow predictions

   Författare :Anna Åkesson; Anders Wörman; Göran Lindström; Rolf Larsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrological modelling; peak flow predictions; distributed routing; parameterisation; stage-dependency; Hydrology; Hydrologi;

   Sammanfattning : Conventional hydrological compartmental models have been shown to exhibit a high degree of uncertainty for predictions of peak flows, such as the design floods for design of hydropower infrastructure. One reason for these uncertainties is that conventional models are parameterised using statistical methods based on how catchments have responded in the past. LÄS MER

5. 4. Investigation of hyperfine structure in Nb and Rh

7. 5. Parameterisation and flow design optimisation of hydraulic turbine draft tubes

   Författare :Daniel Marjavaara; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : In the present energy market, the demands of rehabilitation and modernisation of old constructions are increasing. Among the renewable energy resources, hydropower offers one of the highest potential for further improvements due to the fact that a great number of hydropower plants are ageing and that they are run at off-design conditions.
