Effect of Fluid Viscosity and Iron-Fluid Composition on Damping Ability of Magnetorheological Damper during Hard Turning Process

By P. Sam Paul, D. Madhan, R. Manikandan, Joyal Joseph

Abstract: In manufacturing industry where metal cutting operation take place, tool vibration is an undesirable phenomenon which affects surface finish of the work piece, tool life and cause discomfort to human personal. In order to avoid tool vibration, the concept of magnetorheological (MR) damper was considered in this study. When a magnetic field is applied to the MR fluids, particle chains form and the fluid becomes a semisolid. This transition is …

Application of Schrödinger Wave Equation to Predict Wave Function on the Influence of Displacement

By C. P. Ukpaka, I. C. Okara

Abstract: This research work contains a review of the Finite-Difference Time-Domain method as applied to the time-dependent Schrödinger wave equation, and the basic update equations are derived in their standard form. A simple absorbing boundary condition was formulated and shown to be effective with narrowband wave functions. The stability criterion was derived from a simple, self explaining perspective and found to give better efficiency than earlier attempts. Conclusively, the idea of …

Value Addition of Quartz Gemstones through Gamma Irradiation

By Zahoor Iqbal, Ihsan Ihsanullah, Muhammad Sufaid Khan, Muhammad Sadiq, Tour Jan

Abstract: Color enhancement of gemstones through gamma irradiation is an established technology throughout the world. By value addition, the traders earned manifold prices to these colorless stones as compared to the fresh ones. For the color enhancement of these semi-precious stones, optimized doses of irradiations are required. To get the optical properties of the stones and to investigate the crystal lattice and chemical composition, X-Ray diffraction (XRD) and energy dispersive X-ray …

Low-graded coals to upgrade

By Debabrata Das, Basuki Nath Choudhary, Bangshidhar Goswami

Abstract: Coal can be defined as a chemically and physically heterogenous, “combustible”, sedimentary rock consisting of both organic and inorganic materials. Organically, coal consists primarily of carbon, hydrogen, and oxygen, with lesser amounts of sulphur and nitrogen. Inorganically, coal consists of a range of ash-forming compounds distributed throughout coal. Major types of analysis are proximate analysis, ultimate analysis and calorific value analysis. Heat value or calorific value determines energy content of …
