2. 1. Performance Evaluation of machine tools : A methodology for loaded testing of machine tools

   Author : Theodoros Laspas; Andreas Archenti; Amir Rashid; Atsushi Matsubara; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine tool; loaded test; quasi-static stiffness; accuracy; stiffness measurement; Production Engineering; Industriell produktion;

   Abstract : Machine tools comprise the basic elements of manufacturing. Evaluationof their performance and reliability are necessary for ensuring productquality. READ MORE

4. 2. Forecasting of Icing Related Wind Energy Production Losses : Probabilistic and Machine Learning Approaches

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

   Abstract : 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.

5. 3. Protein Model Quality Assessment : A Machine Learning Approach

   Author : Karolis Uziela; Arne Elofsson; Liam McGuffin; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein Model Quality Assessment; structural bioinformatics; machine learning; deep learning; support vector machine; proq; Artificial Neural Network; protein structure prediction; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Abstract : Many protein structure prediction programs exist and they can efficiently generate a number of protein models of a varying quality. One of the problems is that it is difficult to know which model is the best one for a given target sequence. Selecting the best model is one of the major tasks of Model Quality Assessment Programs (MQAPs). READ MORE

6. 4. Elastohydrodynamic Lubrication of Cam and Roller Follower Applications : Fast and Reliable Predictions of Friction

   Author : Mohammad Shirzadegan; Daniele Dini; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Abstract : Modelling and simulation in tribology, and more specifically of friction in lubricated contacts, has gained increasing attention over the past years. In a lubricated contact, the dissipation of energy is due to the relative motion of the mating surfaces and arise due to direct contact as well as shearing of the lubricant film. READ MORE

7. 5. Dynamic Analysis and Modeling of Machine Tool Parts

   Author : Tatiana Smirnova; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Boring bar vibration during internal turning operations in machine tools is a pronounced problem in the manufacturing industry. Vibration may easily be induced by the workpiece’s material deformation process, due to the bar’s normally slender geometry. READ MORE
