1. 1. Models for tracking in automotive safety systems

   Författare :Fredrik Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; active safety; vehicle tracking; Automotive; radar detections; preventive safety;

   Sammanfattning : This thesis treats the three main components of a tracking system: motion models, sensor models and implementation architecture. A tracking system utilizes models to extract as much information as possible from a set of sensors, with the purpose of estimating the state of a dynamic system. LÄS MER

3. 2. eHomecare – for safety and communication in everyday life : The perspectives of older users, relatives and care managers

   Författare :Charlotta Åkerlind; Christine Gustafsson; Lene Martin; Maria Engström; Mälardalens högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; care managers; content analysis; communication; eHomecare; experiences; information and communication technology; older people; participation; perceptions; relatives; safety; welfare technology; Care Sciences; vårdvetenskap;

   Sammanfattning : The overall aim of this thesis was to examine how eHomecare affects the daily lives of older users and their relatives, with a focus on safety and communication. A further aim was to explore care managers’ perspectives, expectations and experiences of eHomecare and its implementation. LÄS MER

4. 3. Effects of Safety Measures for Pedestrians and Cyclists at Crossing Facilities on Arterial Roads

   Författare :Mohsen Towliat; Institutionen för teknik och samhälle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport technology; arterial roads; interaction points; Keywords: traffic safety; pedestrian and cyclist safety; conflict study; behavioural study; experimental site; control site; physical measure; evaluation design; variable message sign; pedestrian and cycle crossing; speed measurement.; 30 50 road environment; Transportteknik; Road transport technology; Vägtransportteknik;

   Sammanfattning : The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical measures and variable message signs, based on three principles, lower speed, no priority and improved and relevant information, are tested within the framework of this project.

5. 4. Health Losses in Motorcycle Crashes - Injury Analysis of Crashes into Road Barriers and Evaluation of Antilock Braking Systems

   Författare :Matteo Rizzi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antilock Braking Systems; Powered Two Wheelers; Safety; Injury; Stability; Road Barrier; Health Loss; Crash; Motorcycle;

   Sammanfattning : Motorcycles crashes are a growing road safety problem. While the traditional safety approach has focused on protective gear and rider education, with the Vision Zero approach, the designers of the road transport system are considered responsible for its design and operation.

7. 5. Practical Safety Ventilation in Ultraclean Air Operating Rooms

   Författare :Pedro Gandra; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne bacteria-carrying particles; microbial source strength; surgical clothing system; room air distribution system; Keywords: Ultraclean operating room;

   Sammanfattning : PRACTICAL SAFETY VENTILATION IN   ULTRACLEAN AIR OPERATING ROOMS When planning new ultraclean air operating rooms, often the first question is which is the preferred room air distribution system and what system is the best to meet the requirements of microbiological air cleanliness. Today, in Sweden, the requirement is a target level of 5 CFU/m3during the design phase, in order to ensure that the level of ≤10 CFU/m3during infection prone surgery is maintained. LÄS MER
