1. Förarstöd för lägre bränsleförbrukning och minskade emissioner. Utvärdering av två system
Sammanfattning : Det krävs åtgärder på flera nivåer för att minska utsläppsnivåerna från vägtrafiken. I denna uppsats studeras möjligheten att använda förarstöd för att minska den totala bränsleförbrukningen och emissionerna. LÄS MER
2. Simplified dynamic analysis of railway bridges under high-speed trains
Sammanfattning : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. LÄS MER
3. Onboard condition monitoring of vehicle-track dynamic interaction using machine learning : Enabling the railway industry’s digital transformation
Sammanfattning : The railway sector’s reliability, availability, maintainability, and safety (RAMS) can significantly improve by adopting condition based maintenance (CBM). In the CBM regime, maintenance decisions are driven by condition monitoring (CM) of the asset. LÄS MER
4. Wind-induced vibrations in tall timber buildings : Design standards, experimental and numerical modal analyses
Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER
5. A study of vehicle fatigue damage predictions based on state estimations
Sammanfattning : Individual health monitoring of heavy vehicles is one of the keystones on which an optimized utility of a vehicle fleet is based. For many components mounted on the chassis of a heavy vehicle, failures due to fatigue is a major concern. LÄS MER
