2. 21. Reliable Uncertainty Quantification in Statistical Learning

   Author : David Widmann; Fredrik Lindsten; Dave Zachariah; Erik Sjöblom; Dino Sejdinovic; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reliability; Calibration; Uncertainty; Probabilistic Model; Prediction; Julia; Machine learning; Maskininlärning;

   Abstract : Mathematical models are powerful yet simplified abstractions used to study, explain, and predict the behavior of systems of interest. This thesis is concerned with their latter application as predictive models. READ MORE

4. 22. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour

   Author : Sara Florisson; Sigurdur Ormarsson; Johan Vessby; Kent Persson; Linnéuniversitetet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analytical method; calibration; controlled climate; creep; distortion; experimental methodology; FEM; fibre orientation; mechano-sorption; moisture transport; natural climate; Norway spruce; numerical model; three-dimensional; timber beam; validation; wood; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

   Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

5. 23. Probing Interactions between Bio-Fibre Components

   Author : Niklas Nordgren; Mark Rutland; Harry Brumer; Vincent Bulone; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; AFM; QCM-D; cellulose; xyloglucan; surface forces; friction; colloidal probe; nanotribology; biomimetic; enzymatic; polysaccharide; self assembly; grafting; thiol; spring constant; calibration; photodetector calibration.; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : I den här avhandlingen har atomkrafts mikroskopi (AFM) och kvartskristall mikrovåg med dissipation (QCM-D) används för att undersöka interaktioner i bio-fiber modell system av cellulosa och xyloglukan (XG); en naturligt förekommande polysackarid viktig för tillväxt av träd och andra växter. Dessutom har det avgörande momentet av friktionskrafts-kalibrering studerats för att erhålla noggranna och kvantitativa resultat med kolloidal prob AFM. READ MORE

6. 24. Pose Estimation and Calibration Algorithms for Vision and Inertial Sensors

   Author : Jeroen Diederik Hol; Fredrik Gustafsson; Thomas Schön; Patric Jensfelt; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pose estimation; Sensor fusion; Computer vision; Inertial navigation; Calibration; Automatic control; Reglerteknik;

   Abstract : This thesis deals with estimating position and orientation in real-time, using measurements from vision and inertial sensors. A system has been developed to solve this problem in unprepared environments, assuming that a map or scene model is available. READ MORE

7. 25. Dynamic response reconstruction using passive components

   Author : Anders Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

   Abstract : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. READ MORE
