21. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems
Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

22. On Structural Design of High-Speed Craft
Sammanfattning : The development in structural design and construction of high-speed craft has been extensive during the last decades. Environmental and economical issues have increased the need to develop more optimized structures, using new material concepts, to reduce weight and increase performance efficiency. LÄS MER
23. Gait speed and physical exercise in people with dementia
Sammanfattning : The aim of the thesis was to investigate the importance of physical function for survival in very old people, and furthermore, whether physical exercise could influence physical function, cognitive function, and dependence in activities of daily living (ADLs) in older people with dementia living in nursing homes.The world’s population is ageing.

24. Vibration mitigation of high-speed railway bridges : Application of fluid viscous dampers
Sammanfattning : At the moment of writing, an expansion of the Swedish railway network has started, by constructions of new lines for high-speed trains. The aim is to create a high-speed connection between the most populous cities in Sweden - Stockholm, Göteborg and Malmö, and the rest of Europe. LÄS MER
25. Characterization of train-induced aerodynamic loads on high-speed railway vertical noise barriers
Sammanfattning : High-Speed Railway (HSR) technology requires the deployment of noise barriers to mitigate noise pollution affecting nearby residents. As train speeds increase, so does the magnitude of aerodynamic effects such as aerodynamic noise and the pressure on these barriers, meaning that these structures require robust sound insulation and structural load-bearing capacities.
