17. Application of Automated Non-contact Resonance Testing for Low Temperature Behavior of Asphalt Concrete
Abstract : Impact resonance testing is a well-documented non-destructive testing method and its applications on asphalt concrete have also been implemented successfully. The test is carried out manually by inducing an impact in order to excite the test specimen and taking measurements of the vibrational response. READ MORE

18. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles
Abstract : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.
