   Sammanfattning : I avhandlingen undersöker jag språklig stil och stajling bland västnyländska finlandssvenskar i Stockholm i ett material som består av intervjuer och smågruppssamtal med elva deltagare. Avhandlingens syfte är att undersöka den språkliga stilen när deltagarna samtalar med en sverigesvensk person. LÄS MER

3. 17. Computational homogenisation and solution strategies for phase-field fracture

   Författare :Ritukesh Bharali; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; irreversibility; multi-scale; slack variable; micromorphic; quasi-brittle; brittle; phase-field fracture; homogenisation;

   Sammanfattning : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. LÄS MER

4. 18. Sequential Data Learning, Scalable Models and Adversarial Regularization

   Författare :Jin Huang; Ming Xiao; Geyong Min; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Time Series Prediction (TSP) has been used in mobile network traffic data analysis to produce predictive results for network planning and resource allocation. In the first part of this thesis, we propose a novel method of predicting mobile network traffic using neural networks based on conditional probability modeling between adjacent data windows in the time series sequence.

5. 19. Probabilistic machine learning methods for automated radiation therapy treatment planning

   Författare :Tianfang Zhang; Jimmy Olsson; Steve Jiang; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk statistik; Mathematical Statistics;

   Sammanfattning : In this thesis, different parts of an automated process for radiation therapy treatment planning are investigated from a mathematical and computational perspective. Whereas traditional inverse planning is labor-intensive, often comprising several reiterations between treatment planner and physician before a plan can be approved, much of recent research have been aimed at using a data-driven approach by learning from historically delivered plans.

7. 20. On the Dynamics of Porous Media - Application to Road and Railway Structures

   Författare :Bernd Lenhof; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poromechanics; dynamics; railway; multiphasic mixture; hydro-mechanical modeling; internal erosion; road; porous media;

   Sammanfattning : Load-bearing road and railway structures normally consist of layers of particulate porous materials, often with bitumen-based binders. The layered system is subjected to dynamic loading from traffic, which inevitably causes material deterioration that enhances permanent surface deformation. LÄS MER
