1. 1. Structural Integrity Analysis of Critical Elements of RoPax Ships

   Författare :Ulf Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety; IACS UR S8; RoRo; experiments; ship collision; RoPax; finite element analysis; event-chain; bow-door;

   Sammanfattning : The potentially costly consequences of a lost ship in the form of fatalities, property, cargo and related industries, as well as pollution of the environment in the form of oil spill, etc., and the public view are the driving forces for developing safer ships. Especially RoRo-ferries, i.e. LÄS MER

3. 2. Studies of safety and critical work situations in nuclear power plants : a human factors perspective

   Författare :Lena Kecklund; Erik Hollnagel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Safety; nuclear power; operators; work-related factors; performance; human error; annual outage; MTO; Psychology; Psykologi; psykologi; Psychology;

   Sammanfattning : The purpose of this thesis was to develop and apply different approaches for analyzing safety in critical work situations in real work settings in nuclear power plants, and also to identify safety enhancing measures by using the framework of interaction between human, organizational and technical subsystems (MTO, man-technology-organization). A Cognitive Psychology as well as a Stress Psychology framework was used. LÄS MER

4. 3. The development of methods for detection and assessment of safety critical events in car driving

   Författare :Omar Bagdadi; Andras Varhelyi; Nicolas Saunier; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Near miss; Braking; Driving veh ; Driver; Behaviour; Tillbud; Bromsning; Fordonskörning; Förare; Beteende; Road: Road user behaviour; Road: Road user behaviour; Crash involvement; jerk; safety critical event;

   Sammanfattning : Improving our knowledge of drivers’ behaviour, especially in hazardous situations is a key to understanding why accidents occur and how to improve safety on our roads. Crash surrogate measures have proven to be very useful in traffic safety analysis. LÄS MER

5. 4. Safe Transitions to Manual Driving From Faulty Automated Driving System

   Författare :Josef Nilsson; RISE; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver takeover; functional safety; automated driving; safety; vehicle automation; driver capability; brake failure; controllability; driving simulator.;

   Sammanfattning : This thesis presents a method to assess the safety of transitions from automated to manual driving when vehicle automation fails. The method is based on contributions to the understanding of human driving behavior, also presented in this thesis. LÄS MER

7. 5. Scheduling and Optimisation of Heterogeneous Time/Event-Triggered Distributed Embedded Systems

   Författare :Traian Pop; Petru Eles; Zebo Peng; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; embedded computer systems; safety-critical applications; real-time behavior; time-triggered TT ; event-triggered ET ; Computer science; Datavetenskap;

   Sammanfattning : Day by day, we are witnessing a considerable increase in number and range of applications which entail the use of embedded computer systems. This increase is closely followed by the growth in complexity of applications controlled by embedded systems, often involving strict timing requirements, like in the case of safety-critical applications.
