1. Investigation of the structural response of pavements in cold region using instrumented test site data
Sammanfattning : The structural behaviour of pavement structures is known to be affected by the traffic-related loading and by the ambient factors to which the structure is subjected. A new mechanistic-empirical (M-E) pavement design method is under development in Sweden with the main purpose to adequately predict pavement structural response and performance. LÄS MER
2. Validation of heavy vehicle loading responses and temperature predictions in flexible pavements using field data
Sammanfattning : It is well established that both traffic-related loading and environmental conditions influence the structural behaviour of pavements. Pavement design methods aim to consider the effect of traffic loading and environmental variables on pavement structure, foresee their changes during the lifetime of the pavement and predict the resulting distresses and pavement life.

3. Highly Dynamic Drives for Electric Hybrid Vehicles : Electric Machine Design and Dynamic Test Method
Sammanfattning : Electric Hybrid Vehicles (EHVs) play a crucial role in the development towardsa more environmental friendly transportation. An alternative to solve someactual challenges with hybridization of vehicles is studied at the Division ofIndustrial Electrical Engineering and Automation (IEA) at Lund Universityin cooperation with the automotive industry.

4. Excess pore water pressure generation in fine granular materials under cyclic loading -A laboratory study
Sammanfattning : Abstract Excess pore water pressure can be generated in subgrades of both railway and pavement sub-structures under cyclic loading caused by heavy traffic. When saturated subgrades are subjected to cyclic loading, excess pore water pressures accumulate over time which then could lead to migration of particles into overlying layers. LÄS MER
5. Heavy Vehicle Crash Safety - Improved Thoracic Injury Prediction in Frontal Crash Testing
Sammanfattning : Frontal crashes are regarded as some of the most injurious accidents for Heavy Goods Vehicle (HGV) drivers. One of the leading HGV manufacturers regularly conducts frontal crash testing for occupant safety. The Hybrid III crash test dummy was developed for frontal testing in passenger cars and has become the standard in crash laboratories. LÄS MER
