Enhancement of Strassen’s Matrix Using Scilab
Abstract: The paper “Enhancement of Strassen’s Matrix Multiplication” is divided into two phases. 1st phase aims at providing ease in the calculations done in ordinary matrix multiplication and using encryption and decryption techniques which enhances security measures. This paper encourages the people to perform less complex calculations. T(n)=7T(n/2)+O(n^2), nlogba=nlog 27==n^2.81, Master’s method T(n)=O(nlog7). The number 2.81 may not seem much smaller than 3, but because the difference is in exponent, the …

MANET Communication in Embedded Devices through Adjoined Heterogeneous Protocols for Defence Application
Abstract: In this paper, we present a packet management technique for establishing communication by conjoining heterogeneous protocols in MANET that are implemented using Scilab tool in several embedded devices. The module presented here for packet management functions is NARVAL in Scilab. As any network has loads of packets, packet management techniques are necessary for handling the packets in the flow, at the source and also at the destination. The outcome of …

Solidification of Brass Casting in Green Sand Mould: A Numerical and Experimental Study
Abstract: Casting which is also known as founding, is one of the earliest metal shaping methods. It means the pouring of molten metal into the refractory mould then allowing it to solidify. After solidification removing of part from the mould either by breaking the mould or ejecting the mould part. Present study has been focused on solidification of brass in green sand mould formulation. Two-dimensional heat conduction equation in cartesian co-ordinate …

Induction Motor Speed Control Using SCADA
Abstract: Single-phase induction motors are widely used in home appliances and industrial control because of their low cost and rugged construction. Many industrial processes require variable speed drives for various applications. This project investigates the speed control performance of single-phase induction motor using microcontroller AVR ATmega8a. PWM technique has been employed in this inverter to supply the motor with AC voltage. The 4n25 opto-coupler serves the purpose of isolation between the …

Numerical Formulation of Solidification of Aluminum Casting in 2-D Green Sand Mould
Abstract: Unsteady numerical simulation of steady state and unsteady state conduction heat transfer has been done for solidification of pure Aluminium in green sand mould. As during the solidification heat transfer by conduction will dominate over convection and radiation. Heat conduction equation in two-dimensional Cartesian co-ordinate governs the problem. Convective boundary condition has been considered at the interface of the casting part and mould cavity. Heat conduction equation in unsteady state …
