EXPERIMENTAL INVESTIGATION ON CONCRETE BY USING PARTIAL AND FULL REPLACEMENT OF WASTE BROKEN GLASS AS COURSE AGGREGATE
Authors: R.MANIKANDAN, Prof. A.BELCIYAMARY
Abstract
Waste glass powder (WGP) used in concrete making leads to greener and ecofriendly environment. In shops and bus body coaches nearby Karur, many waste glass cuttings go to wastes which are not recycled at present and usually delivered to landfills for disposal. Using WGP in concrete is an interesting possibility for economy on waste disposal sites and conservation of natural resources.
PERFORMANCE IMPROVEMENT OF FRACTIONAL ORDER PLL
Authors: S. Jena, S. Swain, M. C. Tripathy, S. Behera
Abstract
Assemble of Phase Locked Loop (PLL) in Fractional domain is the main objective of this paper. At the beginning basics of Fractional Calculus and Phase Locked Loop is readdressed. The fractional order PLL consists of a low-pass filter, a phase detector and a VCO. The MATLAB SIMULINK and LabVIEW models of both integer and fractional order PLL are analyzed. The modelling of fractional order PLL is organized by means of control modelling blocks in Laplace domain. Time domain analysis is also carried out for fractional order PLL by varying α and β values. It has been observed that lower fractional order PLL’s will require lesser time to reach the required phase as compared to their integer counterparts. Then stability analysis is done by plotting the complete analysis using Nyquist plots.
Turning Constraints of Aluminium Alloy 7075 using CNMG and VNMG Inserts
Authors: Hiren Mandanka, Jaypalsinh Rana
Abstract
Almost 80% of a viable & Army airframe is made of aluminium alloys. It is predictable that the usage of aluminium alloy is to upsurge up to 70% by the year 2025. They are mainly used because of their high strength to weight ratio. This project presents a study of the cutting tool performance of an CNMG Carbide & VNMG carbide tool in operation on Al 7075, in which the volume of material removed and surface roughness were investigated.
