Conventional one way migration methods exclude turning waves and multiples. We propose an algorithm that uses multiple passes to extend the one way method to efficiently include these wavepaths. A comparison of the images produced by the regular one way algorithm, RTM, and the new method, shows that this new method can significantly improve the image in regions of interest, and in certain situa...

Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

Edge race-tracking is a frequently reported issue during resin transfer molding. It caused by highly permeable channels and areas between the preform edge cavity, which can significantly change impregnation pattern. To date, information scarce on effect of in compression molding (CRTM). close this gap, laboratory equipment was developed to study CRTM via flow visualization experiments. The ther...

Composite moulds constitute an attractive alternative to classical metallic when used for components fabricated by processes such as Resin Transfer Moulding (RTM). However, there are many factors that have be accounted if a correct design of the is sought after. In this paper, Finite Element Method (FEM) help in mould. To do so, thermo-electrical simulation has been performed through MSC-Marc p...

Hemolytic uremic syndrome (HUS) is a life-threatening infectious disease in childhood for which there is no confirmed therapeutic strategy. Endothelial inflammation leading to microthrombosis formation via complement activation is the main pathology of HUS. Thrombomodulin is an endothelial membrane protein that has anticoagulation and antiinflammatory effects, including the suppression of compl...
