1. 6. Forecasting of Icing Related Wind Energy Production Losses : Probabilistic and Machine Learning Approaches

   Författare :Jennie Molinder; Anna Sjöblom; Heiner Körnich; Hans Bergström; Erik Nilsson; Sue Ellen Haupt; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind energy; Icing on wind turbines; Machine learning; Probabilistic forecasting; Meteorologi; Meteorology;

   Sammanfattning : Icing on wind turbine blades causes significant production losses for wind energy in cold climate. Next-day forecasts of these production losses are crucial for the power balance in the electrical grid and for the trading process, but they are uncertain due to lack of understanding of, and simplifications, in the modelling chain.

3. 7. Enhancing aftermarket demand planning with product-in-use data

   Författare :Joakim Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Big data; Digitalization; Product-in-use.; Forecasting; Demand planning; Aftermarket;

   Sammanfattning : Enhancing aftermarket demand planning with product-in-use data ABSTRACT Aftermarket demand planning, consisting of forecast and known demand, is a critical activity for both the uptime of customers’ products and the supply chain-related costs. Traditional aftermarket forecasting methods use historical demand as the only input to the statistically based forecasts, usually combined with judgmental modifications. LÄS MER

4. 8. Solar Wind and Geomagnetic Activity - Predictions Using Neural Networks

   Författare :Hans Gleisner; Astronomi - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; kosmisk kemi; rymdvetenskap; magnetosphere; solar wind; space weather; geomagnetic activity; geomagnetism; ring current; auroral electrojet; neural networks; forecasting; Astronomy; space research; Astronomi; cosmic chemistry; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Fysicumarkivet A:2000:Gleisner;

   Sammanfattning : This thesis shows how artificial neural networks (ANNs) can be applied to predict geomagnetic activity from solar-wind data. It introduces and summarizes five papers where development of ANN models are reported, and where predictions of geomagnetic activity are discussed. LÄS MER

5. 9. Pharmacometric Approaches to Improve Dose Individualization Methods in Hemophilia A

   Författare :João A. Abrantes; Mats Karlsson; Elisabet I. Nielsen; Siv Jönsson; Ron Mathôt; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bayesian forecasting; coagulation factor VIII; dose adaptation; hemophilia haemophilia A; inter-occasion variability; NONMEM; pharmacodynamics; pharmacokinetics; pharmacometrics; therapeutic drug monitoring; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Hemophilia A is a bleeding disorder caused by the lack of functional coagulation factor VIII (FVIII). The overall aim of this thesis was to improve dose individualization of FVIII replacement therapy in hemophilia A using pharmacometric approaches. LÄS MER

7. 10. Parking support model for open parking lots

   Författare :Vijay Paidi; Johan Håkansson; Roger G. Nyberg; Hasan Fleyeh; Seifedine Kadry; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; parking; deep learning; pollution; cruising; detection; tracking; forecasting;

   Sammanfattning : Parking is a common process performed by vehicle drivers when they arrive at their destination. It is considered to be the last mile transportation problem of personal vehicles. Some of the common problems observed by drivers are additional cruising, congestion, pollution, and driver frustration. LÄS MER
