The bearing is a machine element that plays an important role in rotating the shaft of while supporting its weight and load. Numerous bearings have been developed to improve durability life, depending on functions operating conditions which they are desired. White metal one method soft bonded inner surface protect shaft. Currently, centrifugal casting process used as white lamination method, bu...

We analyze an elliptical core segmented cladding fibre using the vector finite element method (FEM) and show that the segmented cladding can effectively control the birefringence of the fibre. The analysis should be useful for fibre-based polarization controlling devices and single-polarization devices.

We prepared a bone scaffold material comprising a PLGA/β-TCP core and a Type I collagen cladding, and recombined it with bone marrow stroma stem cells (BMSCs) to evaluate its potential for use in bone tissue engineering by in vivo and in vitro experiments. PLGA/β-TCP without a cladding was used for comparison. The adherence rate of the BMSCs to the scaffold was determined by cell counting. Cell...

In this work we report experimental results on optimizing the refractive index (RI) sensitivity of long-period gratings (LPGs) by fiber cladding etching and thin aluminum oxide (Al2O3) overlay deposition. The presented LPG takes advantage of work in the dispersion turning point (DTP) regime as well as the mode transition (MT) effect for higher-order cladding modes (LP...

An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...
