1. 1. On Evaluation and Modelling of Human Exposure to Vibration and Shock on Planing High-Speed Craft

   Författare :Katrin Olausson; Karl Garme; Jakob Kuttenkeuler; Dominic J. Taunton; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whole-body vibration; high-speed craft; working conditions; seat modelling; apparent mass; ergonomics; human factors; ISO 2631-1; ISO 2631-5; extreme values; acceleration statistics; slamming;

   Sammanfattning : High speed in waves, necessary in for instance rescue or military operations, often result in severe loading on both the craft and the crew. To maximize the performance of the high-speed craft (HSC) system that the craft and crew constitute, balance between these loads is essential. LÄS MER

3. 2. 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

4. 3. Child Safety in Car Crashes

   Författare :Marianne Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reconstructions; near-side; evaluations; frontal impact; rigid body; mathematical simulations; rear seat; finite elements; belt positioning booster; side impact; child safety; child seat;

   Sammanfattning : Traffic related trauma is the most common cause of fatality and severe injury to children in developed countries. The majority of these fatalities and injuries are caused by frontal and side impacts. LÄS MER

5. 4. Aristokratiskt rum och gränsöverskridande. Järrestad och sydöstra Skåne mellan region och rike 600-1100

   Författare :Bengt Söderberg; Arkeologi; []
   Nyckelord :HUMANIORA; HUMANITIES; ethnicity; region; manor; central place complex; materialized ideology; border-crossing; specialized craft; feasting; cosmology; social space; high seat; hall; rulership ideology; lordship; network; aristocracy; Järrestad; early medieval period; identity; Archaeology; Arkeologi; Sociala förhållanden;

   Sammanfattning : This dissertation focuses on the second wave of central places in south Scandinavia, emerging during the prolonged 7th century. The point of departure is a case study of an aristocratic setting in Järrestad, situated in the southernmost part of Sweden. Two problem complexes are tackled: 1. LÄS MER

7. 5. Front seat passengers’ experience of ride comfort and NVH in modern cars

   Författare :Xiaojuan Wang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ride comfort; Sound and Vibration;

   Sammanfattning : Due to the refinements in combustion-engine and electric cars, ride comfort has become a prominent attribute when it comes to developing cars in the future. A variety of factors, such as seat, seatbelt, sound and vibration, have been shown to influence perceived overall ride comfort in passenger cars. LÄS MER
