1. 1. The Contribution of Vehicle, Occupant and Other Factors to the Risk of Injury as a Result of Vehicle Rollover

   Författare :Stephen Ridella; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intrusion; Kinematics; Injury Causation; Roof Inversions.; Rollover; CIREN; NASS-CDS; Restraints;

   Sammanfattning : Injuries and deaths as a result of vehicle rollover have been declining in recent years like other crash modes, but it still remains a consistently large contributor of the overall crash fatalities in the United States. Also, more new vehicles are becoming equipped with electronic stability control and are subject to new regulations that call for increased roof strength and countermeasures to prevent ejection during rollover crashes.

4. 3. Organising Industrial Activities - An analytical framework

   Författare :Anna Dubois; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activity structures; complementarities; activities; activity chains; dependencies; boundaries; networks; similarities;

   Sammanfattning : The way in which industrial activities are organised among firms has been a fundamental theoretical concern for a long time. In practice, firms have found these matters, referred to as make-or-buy issues, difficult to analyse. LÄS MER

5. 4. Development of a Mechanical Model for Rear Impacts: Evaluation of Volunteer Responses and Validation of the Model

   Författare :Johan Davidsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whiplash; validation; rear impact; dummy; seat; spine; rear-end collision; volunteer; BioRID; neck;

   Sammanfattning : The objective of this research has been to develop a biofidelic crash-test dummy to facilitate design of seat systems with enhanced occupant protection in rear-end collisions. These frequent collisions may cause soft-tissue neck injuries to occupants in struck vehicles. LÄS MER

7. 5. Control of Cracking due to Imposed Strains in Concrete Structures

   Författare :Dan Pettersson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; Friction.; Restraint; Shrinkage; Imposed deformations; Minimum reinforcement; Crack widths; Reinforced concrete; Crack development; Crack control; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : This thesis is concerned with crack control due to imposed deformations in concrete structures. The objective of crack control may either be to prevent cracking or to limit the crack widths. The aim here is to increase the knowledge in both fields for some common structures. Five papers are included and the three last concern crack development. LÄS MER
