Energy-Based Evaluation and Remediation of Liquefiable Soils
… data in remedial ground densification design via energy-based concepts. The energy dissipated by frictional mechanisms during the relative movement of sand grains is hypothesized to be directly related to the ability of a soil to resist liquefaction (i.e., Capacity). This hypothesis is supported …

Development of an Energy-based Liquefaction Evaluation Procedure
… The objective of this research is to develop an energy-based approach for evaluating the potential for liquefaction triggering. The current state-of-practice for the evaluation of liquefaction triggering is the "simplified" stressbased framework where resistance to liquefaction is correlated to …

Development and analysis of solar energy based multigeneration systems
In this thesis three novel multigeneration energy systems are introduced based on renewable resources such as solar and wind energy. The results of the analyses show that, System 1 has a maximum energy efficiency of 43% and a maximum exergy efficiency of 65%, based on the produced maximum power of …

Energy based dissolution simulation using smoothed particle hydrodynamic sampling
… and games. The desire for an improved physically-based fluid simulation solver has grown hand in hand with the advances made in Computer Graphics. Interesting fluid behaviours emerge when solid objects are added to a simulation: when fluid and solid make contact, they do not only have a physical …

Assessment of Crash Energy - Based Side Impact Reconstruction Accuracy
… of ?V is caused by over-estimation of the energy absorbed by struck vehicle damage. In turn, this ultimately stems from the vehicle stiffness parameters used by WinSMASH for this purpose. When WinSMASH was forced to use the correct amount of absorbed energy to reconstruct the crash tests, …

Model based control optimisation of renewable energy based HVAC Systems.
… efficiently and some are, from the primary energy point of view, even worse than conventional systems with a compression chiller. The main reason for this is a poor system design combined with suboptimal control. Often several non optimised components, each separately controlled, are put …
