1. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön
Master-uppsats, KTH/SpårfordonSammanfattning : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. LÄS MER
2. Digitalization in the rail industry: Localizing damaged cargo wagons using spatial operations and big data
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Climate change and the sustainability challenges of the 21st century require the reduction of greenhouse gas emissions in all sectors. Accordingly, political objectives urge for a shift from road to rail in logistics. This drives innovation, increased efficiency, and customer friendliness in the rail industry. LÄS MER
3. Investigation of sources of wheel-rail impact force deviation through dynamic simulations
Master-uppsats, KTH/FordonsdynamikSammanfattning : Due to the increase in demand on freight transportation it becomes necessary to avoid delays to ensure that the goods reach its destination on time. The main factors causing disturbances in the traffic on the mainline is the breakdown of vehicles mainly due to damaged wheels. LÄS MER
4. Sensitivity analysis of pluvial flood modelling tools for dense urban areas : A case study in Lundby-Lindholmen, Gothenburg
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : As a result of the global climate change, extreme precipitation is occurring more frequently which increases the risk of flooding, especially in urban areas. Urbanisation is widely discussed regarding urban flooding where an increase of impervious surfaces limits the infiltration and increases the surface runoff. LÄS MER
5. Ankarskenor i byggandet
Uppsats för yrkesexamina på grundnivå, Malmö universitet/Fakulteten för teknik och samhälle (TS)Sammanfattning : Vårt examenarbete om ankarskenor i byggandet omfattar implementering av en ny teknik i byggandet i form av föringjutna ankarskenor för installationer av VS rör, ventilation, sprinkler och EL. I en allt mer globaliserad värld råder en allt högre konkurrensutsatt marknad, vilket gör att det också ställs högre krav på entreprenörerna inom byggsektorn. LÄS MER
