1. Optimization of a Floor Grinding Machine for Uniform Grinding Pattern
Master-uppsats, Linköpings universitet/ProduktrealiseringSammanfattning : Husqvarna Construction is one of the leading construction machinery manufacturers in the world. To stay in the forefront, investing in novel methods to model, test & and optimize machinery is crucial. The most important part of development and testing is to bridge the gap between desired and actual results. LÄS MER
2. En learning study om brobyggen : en studie om teknikundervisning i lågstadiet
Uppsats för yrkesexamina på avancerad nivå, Högskolan i Borås/Akademin för bibliotek, information, pedagogik och ITSammanfattning : I en granskning av Skolinspektionen 2014 framkom alarmerande information att den svenska skolan ofta misslyckas med undervisning i teknik där fallande elevintresse för ämnet är en stor konsekvens. I Sverige tillkom en ny läroplan höstterminen 2022 som lyfter att teknikundervisning ska verka för att eleverna utvecklar teknisk medvetenhet och intresse. LÄS MER
3. Numerical modelling of high-speed railway transition zone
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Transition zones are changes in the track structure, detected by an abrupt deviationin track stiffness and/or differential settlements. One inevitable transition zone is thebridge approach. This study has investigated in this transition zone, adapted for highspeed,ballastless track. LÄS MER
4. Sustainable concrete bridges : An investigation of possible measures to reduce the climate impact
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : The need of building new bridges is always existing in relation with the increase of infrastructureand transport needs. Bridge constructions have traditionally been associated with highconsumption of resources and large greenhouse gas emissions. LÄS MER
5. Design of footbridges subjected to dynamic loading
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : Modern design of steel pedestrian bridges often results in relatively light constructions with low natural frequencies were there is a considerable risk of resonance to occur from loads due to pedestrians. To resolve the problem a common solution is to increase dimensions of load bearing elements, resulting in greatly oversized elements with increasing costs and have substantial environmental impact.
