    Abstract: Uncertainties are always present in Analysis and design of Engineering systems, but conventional approach simplify the problem by considering the uncertain parameters to be deterministic in which are not and accounted for the uncertainties through the use of empirical safety factors which are derived based on experience. In this study, reliability ... Show More

    Abstract: The composites of biodegradable high density polypropylene (HDPE) reinforced with short coir fiber were prepared by melt mixing followed by hot press molding. The effect of fiber addition on some physical and mechanical properties was evaluated. Different process parameters (e.g. mixing time, heating temperature and time, cooling time etc.) were es...

    Abstract: It has been discussed the opportunity of the spontaneous magnetic field (SMF) observation in turbulent hot plasma which formed as the result of power laser beam interaction with porous low density matter. The sources of SMF appearance are the crossed gradients of electron pressure and plasma density, which arise in the turbulent zone and increase w... Show More

    Abstract: Liquid-gas two-phase flows are widely encountered in industrial applications including chemical processes, petroleum engineering and energy manufacturing units systems. Of all flow patterns encountered in field operations, slug flow is the dominant one in horizontal and near horizontal pipelines, and is also the most complicated one. Of all flow to... Show More
