ABSTRACTParticulate filled polymeric composites are becoming attractive because of their wide applications and lower production cost. To evaluate the possibility of using waste silica based ceramic materials as reinforcing filler in recycled polyethylene (PE) composite, the effect of ceramic (PC)…

The environmental problem conexists with the birth and development of human being. When people entered on the Industrial Revolution, especially the twentieth century, with the rapid improvement of the productivity level, the natural resources has been exploited and used at…

In high temperature coal mine, the surface air cooler heat exchange efficiency decreases greatly because of high humidity and dust. In order to improve the heat exchange efficiency, the surface of the air cooler needs to be designed to reduce…

This paper integrates analytical and experimental investigations of thermal and combustion phenomena during the self-propagating combustion synthesis of Ni - Ti intermetallic for structural bio-implant application. Ni - Ti mixture is prepared from elemental powders of Ni and Ti. The…

In this paper, we discuss a repairable linear C (2, 3; G) system. One repairman carries out the maintenance of the system. It is assumed that the working time and the repair time of each component in the system are…

Viscous flow drag represents the largest contingent of the entire drag that aerodynamic and hydrodynamic devices are subject to. Inspired by the functions of sharks skins, riblet surfaces have been studied and applied to wall structures to reduce turbulent flow…

This paper derives the probabilistic continuous review backorders and lost sales inventory system when the order cost is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected…

Nanoparticles filling is one of the most effective methods to build the micro-nano structure. In this paper, the composite coatings containing Fe3O4 nanoparticles were prepared from fluorinated silicon polymer by in-situ polymerization. FT-IR was used to characterize the structure of…

PKI system supports user authentication, message transmission, data integrity, message storage confidentiality, and the non-repudiation of operation. PKI can completely address e-commerce security requirements and PKI technology has been applied successfully in e-commerce as well. This article studies the system…

The way of heating the air electricity transmission line by spreading it on a running high-frequency electromagnetic waves, which is to protect the electric power system from ice storm. At the heart of the heating are two physical phenomena: the…
