  2. 1. On Statistical Methods for Safety Validation of Automated Vehicles

    Author : Daniel Åsljung; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; performance evaluation; extreme value theory; Automotive; validation; automated vehicles; simulation; verification; automated driving systems;

    Abstract : Automated vehicles (AVs) are expected to bring safer and more convenient transport in the future. Consequently, before introducing AVs at scale to the general public, the required levels of safety should be shown with evidence. However, statistical evidence generated by brute force testing using safety drivers in real traffic does not scale well. READ MORE

  4. 2. Specifying and Operationalizing an Organizational Theory of Crowdsourcing

    Author : John Prpic; Åsa Wallström; Jan Kietzmann; Mana Farshid; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crowdsourcing; organizations; theory specification; theory operationalization; theory validation; Industrial Marketing; Industriell marknadsföring;

    Abstract : Introduction: Despite rapid developments across multiple areas of research and practice, an organizational-level theory of Crowdsourcing has yet to emerge.Objectives: Therefore, this thesis has two major objectives; 1) specify the boundaries, constructs, and relationships of an organizational-level theory of Crowdsourcing, and 2) begin the theoretical validation process by operationalizing the theory for new exploratory, explanatory, and conceptual research.

  5. 3. Efficient Full-Scale CFD for Ship Hydrodynamics

    Author : Michal Orych; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CFD; Self-propulsion; Ship; Verification; Uncertainty; Full-scale; Validation; Seakeeping; Energy-Saving Device; Roughness; RANS;

    Abstract : An efficient numerical approach for ship hydrodynamics, involving a hybrid free-surface potential flow/RANS method, is explored. The work focuses on estimating the delivered power of ships in calm water and in waves, highlighting the benefits of full-scale simulations, particularly for ships with Energy Saving Devices.

  6. 4. Heterogeneous Knowledge Sharing in eHealth : Modeling, Validation and Application

    Author : Yang Guo; Guohua Bai; Eriksén Sara; Anita Mirijamdotter; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Knowledge sharing; eHealth; Activity Theory; Ontology; Decision making; Appointment scheduling;

    Abstract : Knowledge sharing has become an important issue in the eHealth field for improving the quality of healthcare service. However, since eHealth subject is a multidisciplinary and cross-organizational area, knowledge sharing is a serious challenge when it comes to developing eHealth systems. READ MORE

  7. 5. On Safety Validation of Automated Driving Systems using Extreme Value Theory

    Author : Daniel Åsljung; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Verification; Autonomous Vehicles; Performance Evaluation; Automotive;

    Abstract : Autonomous vehicles are expected to bring safer and more convenient transports in the future. When the system in the vehicle takes care of the driving, the driver is free to spend time on other things. READ MORE
