21. Optimization of Vehicle Structures under Uncertainties
Sammanfattning : Advancements in simulation tools and computer power have made it possible to incorporate simulation-based structural optimization in the automotive product development process. However, deterministic optimization without considering uncertainties such as variations in material properties, geometry or loading conditions might result in unreliable optimum designs. LÄS MER
22. Computationally Efficient and Adaptive Energy Management Strategies for Parallel Hybrid Electric Vehicles
Sammanfattning : Hybrid electric vehicles (HEVs) are irreplaceable in attaining sustainable development in contemporary society. Owing to the extra degree of freedom in supplying traction power, HEVs resort to appropriate energy management strategies (EMSs) to present their superiority over conventional internal combustion engine vehicles and pure electric vehicles.

23. Studies on Diesel sprays under non-reacting and reacting conditions
Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER
24. Subcooled boiling flow in liquid-cooled internal combustion engines
Sammanfattning : Road transport sector contributes significantly to emission of carbon dioxide and other greenhouse gases, which negatively impact the global climate. Efficient management of energy, irrespective of the type of propulsion, has the potential to minimize fuel consumption and to reduce emission of greenhouse gases. LÄS MER
25. Perceived Quality of Cars. A Novel Framework and Evaluation Methodology
Sammanfattning : The supremacy of the automotive manufacturers today is no longer driven by them achieving a superior manufacturing quality but increasingly depends on the customer’s quality perception. Average car consumers see a car’s quality as a fancy mixture of design, aesthetics, their own previous experiences and performance characteristics of the vehicle, unlike a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved in the modern car creation.
