1. Safety leadership in the construction industry : Managing safety at Swedish and Danish construction sites
Sammanfattning : The overall aim of this thesis was to identify and describe essential components of safety leadership behavior in the construction industry in Sweden and Denmark. The methods used were semi-structured interviews, cross-sectional and longitudinal questionnaire studies, and behavioral observations. LÄS MER
2. Safety at Rail-Road Level Crossings
Sammanfattning : Safety related to traffic at rail/road level crossings has long been a major issue for rail operators all over the world. Eliminating these level crossings entirely would be a desirable solution. However converting them into separate types is very expensive and not reasonable in many cases, e.g. LÄS MER
3. Inherent Safety Features and Passive Prevention Approaches for Pb/Bi-cooled Accelerator-Driven Systems
Sammanfattning : This thesis is devoted to the investigation of passivesafety and inherent features of subcritical nucleartransmutation systems - accelerator-driven systems. The generalobjective of this research has been to improve the safetyperformance and avoid elevated coolant temperatures inworst-case scenarios like unprotected loss-of-ow accidents,loss-of-heat-sink accidents, and a combination of both theseaccident initiators.

4. Investigations of passive safety systems in LWRs : melt coolability with bottom coolant injection, light gas effects on a passive containment cooling system
Sammanfattning : The key objectives in introducing passive features in thesafety systems for Light Water Reactor (LWR) are to increasetheir reliability, to simplify the design of the plants and toimprove performance and economics. Component and integralsystem tests in scaled facilities are required for optimizingthe design and for certification of these safety systems. LÄS MER
5. Integrated Pedestrian Safety Assessment: A Method to Evaluate Combinations of Active and Passive Safety
Sammanfattning : Pedestrian road casualties are a major concern in many countries. Vehicle safety systems attempt to reduce casualties, and the accurate assessment of such systems is therefore essential. Passive safety assessment is well established, and additional active safety assessment has recently emerged. LÄS MER
