  2. 1. Towards Intelligent Deformable Models for Medical Image Analysis

    Author : Ghassan Hamarneh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape modeling; deformable models; principal component analysis; echocardiography; snakes; active shape models; deformable spatio-temporal shape models; medial-based shape profiles; statistical shape variation; spatio-temporal shape analysis; magnetic resonance imaging; hierarchical regional principal component analysis; oral lesions; dynamic programming; segmentation; spring-mass model; shape deformation; optical flow; medical image analysis; artificial life; physics-based modeling; deformable organisms; digital color images; medial axis; active contour models;

    Abstract : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

  4. 2. Safety Analysis of Systems-of-Systems

    Author : Stephan Baumgart; Joakim Fröberg; Sasikumar Punnekkat; Iain Bate; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-of-Systems; Safety Analysis; Hazard Analysis; Model-based Development; Computer Science; datavetenskap;

    Abstract : Safety-critical systems may fail dangerously with severe consequences to the health of the involved humans, costly equipment, the environment, or other valuable assets of a stakeholder. For these classes of systems, the developers are obliged to analyze each potentially hazardous situation thoroughly. READ MORE

  5. 3. Issues of Complex Hierarchical Data and Multilevel Analysis : Applications in Empirical Economics

    Author : Joel Karlsson; Ghazi Shukur; Håkan Locking; Scott Hacker; Linnéuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Multilevel modelling; Hierarchical modelling; Single farm payments; Part-time unemployment; Educational attainment; Performance evaluation; Economics; Nationalekonomi;

    Abstract : This thesis consists of four individual essays and an introduction chapter. The essays are in the field of multilevel analysis of economic data. The first essay estimates capitalisation effects of farm attributes, with a particular focus on single farm payments (SFP), into the price of farms. READ MORE

  6. 4. System analysis of kitesurfing : Understanding performance and injury risk for on-water board sports

    Author : Lina Lundgren; Sofia Brorsson; Anna-Lisa Osvalder; Högskolan i Halmstad; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sport performance; sport injury; musculoskeletal stress; system analysis; usability problems; human movement; Sports; Idrott; MEDICINE; MEDICIN;

    Abstract : Board sports are examples of sports where the interaction of the task, environment and the athlete are essential. As for other sports, there are injuries and other issues associated with these sports, which affect performance and that can be avoided by proper preparation and well- designed equipment. READ MORE

  7. 5. Hierarchical Concurrent Systems from a Model-Oriented perspective

    Author : Daniel Einarson; Data Vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; control; systems; numerical analysis; Computer science; Distributed Systems; Hierarchical Systems; Object-Orientation; Model-Orientation; Datalogi; numerisk analys; system; kontroll; Systems engineering; computer technology; Data- och systemvetenskap;

    Abstract : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. READ MORE
