1. 1. Pre-Crash and In-Crash Car Occupant Safety Assessment

   Författare :Alexandros Leledakis; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crash Configurations; Advanced Driver Assistance Systems ADAS ; Human Body Model; Crashworthiness; Intersection crashes; Occupant postures; Real-world safety;

   Sammanfattning : Tens of millions are annually injured in Road Traffic Accidents (RTAs) worldwide, while the estimated number of RTA fatalities amounted to 1.35 million in 2016. In Europe, car occupants hold the largest share (48%) of fatalities among all road users. The high fatality and injury numbers motivate the work of enhancing road traffic safety. LÄS MER

3. 2. Fatal car crash configurations and injury panorama : with special emphasis on the function of restraint system

   Författare :Mats Lindquist; Ulf Björnstig; Anders Kullgren; Umeå universitet; []
   Nyckelord :Surgery; Deep studies; fatal crashes; small overlap; human FE-modeling; body kinematics; real life safety; Kirurgi; kirurgi; Surgery;

   Sammanfattning : Background: Most traffic safety research projects require accurate real world data which is collected in different databases around the world. This is especially important since the results of these projects form the basis for new crash test procedures and standards. LÄS MER

4. 3. Heavy Vehicle Crash Safety - Improved Thoracic Injury Prediction in Frontal Crash Testing

   Författare :Kristian Holmqvist; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element modelling; Pendulum test; Injury assessment; Accidents; Chest injury; Hybrid III; Heavy goods vehicle; THUMS; Crash test;

   Sammanfattning : Frontal crashes are regarded as some of the most injurious accidents for Heavy Goods Vehicle (HGV) drivers. One of the leading HGV manufacturers regularly conducts frontal crash testing for occupant safety. The Hybrid III crash test dummy was developed for frontal testing in passenger cars and has become the standard in crash laboratories. LÄS MER

5. 4. Types for Crash Preventionn

   Författare :Lars Pareto; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reliability; dependability; concurrent programming; denotational semantics; real-time systems and embedded systems; data-flow; dynamic storage management; applicative functional programming languages ; type systems;

   Sammanfattning : This thesis seeks to strengthen the capabilities of static polymorphic type-checking (as known from typed lambda calculus and functional programming) to allow a larger class of programming errors to be caught at compile time: the goal is to not only prevent illegal uses of data, but to also errors that lead to busy-loops, deadlocks, stack-overflows and heap-overflows. The thesis exploits that, for recursive programs, many correctness properties (including freedom from errors leading to busy-loops, etc. LÄS MER

7. 5. Heterogeneity in Car Occupant Safety

   Författare :Alexandros Leledakis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-world safety; Human Body Model; Occupant posture; Crash Configurations; Anthropometric variation; Finite element; Sensitivity analysis; Individualised Restraint Systems; Vehicle safety assessment; Seat adjustment;

   Sammanfattning : This thesis ultimately aims to enhance occupant protection by incorporating aspects of real-world crash heterogeneity, often overlooked within current safety assessments. By investigating the effects of crash heterogeneity and broadening the comprehensiveness of occupant safety assessments, it seeks to support the development of more effective future vehicle safety systems.
