An improved moving particle semi-implicit method for dam break simulation
No full textDam break is quite a common and hazard phenomenon in shipbuilding and ocean engineering. The objective of this study is to investigate dam break hydrodynamics with improved Moving Particle Semi-implicit method (MPS). Compared to traditional mesh methods, MPS is feasible to simulate surface flows with large deformation, however, during the simulation, the pressure oscillates violently, due to misjudgment of surface particles as well as particles gathering together. To modify these problems, a new arc method is applied to judge free surface particles, and a collision model is introduced to avoid particles from gathering together. Hydrostatic pressure is simulated by original and improved MPS. The results verify that improved MPS method is more effective. Based on these, dam break model is investigated with improved MPS

No full textOptimized MEMS-based tensile devices towards the generation of extreme strain in CVD graphene
No full textStrain engineering of graphene has been predicted to change its chemical reactivity, thereby forming the basis for new applications, like hydrogen storage. Extreme strains of more than 10% are required for these applica- tions. However, experimental verification of theoretical predictions is still greatly lacking. Such high strains could simply not be controllably achieved. In our group, MEMS based tensile devices were developed to gen- erate large strain on graphene membranes. In this thesis, graphene grown by Chemical Vapor Deposition was transferred and clamped on these devices. In-situ Raman spectroscopy measurements were performed, while straining the material. Scanning Electron Microscope images proved that the fracture strain was ex- ceeded, rupturing the membrane. Nonetheless no Raman peak shift was observed, opposed to what was expected from the literature.Micro and Nano EngineeringPrecision and Microsystems EngineeringMechanical, Maritime and Materials Engineerin
Measuring industry-science links through inventor-author relations: A profiling method
Full text linkIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;
