  2. 1. Learning Predictive Models from Electronic Health Records

    Author : Jing Zhao; Lars Akser; Henrik Boström; Nada Lavrač; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Data Science; Machine Learning; Predictive Modeling; Data Representation; Health Informatics; Electronic Health Records; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : The ongoing digitization of healthcare, which has been much accelerated by the widespread adoption of electronic health records, generates unprecedented amounts of clinical data in a readily computable form. This, in turn, affords great opportunities for making meaningful secondary use of clinical data in the endeavor to improve healthcare, as well as to support epidemiology and medical research.

  4. 2. Stress Effects on Solute Transport in Fractured rocks

    Author : Zhihong Zhao; Lanru Jing; Ivars Neretnieks; Auli Niemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fractured rocks; Solute transport; Stress effects; Coupled stress-flow-transport processes; Analytical solution; Particle mechanics model; Fracture surface damage; Discrete element method; Particle tracking method;

    Abstract : The effect of in-situ or redistributed stress on solute transport in fractured rocks is one of the major concerns for many subsurface engineering problems. However, it remains poorly understood due to the difficulties in experiments and numerical modeling. READ MORE

  5. 3. Scale and Stress Effects on Hydro-Mechanical Properties of Fractured Rock Masses

    Author : Alireza Baghbanan; Lanru Jing; Jian Zhao; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aperture-trace length correlation; Discrete Fracture Network DFN ; Representative Elementary Volume REV ; Strength; Stress-Strain curve; Discrete Element Method DEM ; Stress effect; Deformability of fractures; Earth sciences; Geovetenskap;

    Abstract : In this thesis, the effects of size and stress on permeability, deformability and strength of fractured rock masses are investigated. A comparison study was carried out to examine the effects of considering, or not considering, the correlation between distributions of fracture apertures and fracture trace lengths on the hydro-mechanical behavior of fractured rocks.
