11. Data-driven lead-acid battery lifetime prognostics
Sammanfattning : To efficiently transport goods by heavy-duty trucks, it is important that vehicles have a high degree of availability and in particular avoid becoming standing by the road unable to continue the transport mission. An unplanned stop by the road does not only cost due to the delay in delivery, but can also lead to a damaged cargo. LÄS MER
12. Development and characterization of functional composite materials for advanced energy conversion technologies
Sammanfattning : The solid oxide fuel cell (SOFC) is a potential high efficient electrochemical device for vehicles, auxiliary power units and large-scale stationary power plants combined heat and power application. The main challenges of this technology for market acceptance are associated with cost and lifetime due to the high temperature (700-1000 oC) operation and complex cell structure, i. LÄS MER
13. Experimental Verification of Superconductor Digital Circuits
Sammanfattning : AbstractSuperconducting digital technology based on Rapid Single Flux Quantum (RSFQ) logic offers a 50 times faster clock rate and 100 times less on chip power consumption than today's mainstream semiconductor electronics. This technology is attractive for many applications and in particular for Digital Signal Processing (DSP). LÄS MER
14. Machine Learning Models for Predictive Maintenance
Sammanfattning : The amount of goods produced and transported around the world each year increases and heavy-duty trucks are an important link in the logistic chain. To guarantee reliable delivery a high degree of availability is required, i.e., avoid standing by the road unable to continue the transport mission. LÄS MER
