Abstract: Development of an alternative to conventional cement binder has become the essential need in the construction industries. Production of the conventional constituents of concrete particularly Portland cement exploits significant amount of natural resources and emits equivalent amountof carbon dioxide to the atmosphere. Research made on making binder without cement has come to a viable level of developing geopolymers.Industrial wastes and by products that are pozzolanic in nature are being used as source material and activated using alkaline solutions to use as binder...........

Abstract: Dual-tone-multiple-frequency (DTMF) controlled vehicle is a specific idea in automotive whose actions can be controlled by a mobile phone from all over the world using the DTMF signaling. Traditionally wireless controlled vehicles make use of RF (radio frequency) circuits, which have its own disadvantages of restricted operational range, limited frequency range and limited control. Use of mobile phones for robotic controls provides working range as large as the coverage area of the service provider and no interference with other controllers. I can propose a microcontroller based less effort oriented..........

Abstract: There are several available renewable sources of energy, among which Wind Power is the one which is most uncertain in nature. This is because wind speed changes continuously with time leading to uncertainty in availability of amount of wind power generated. Hence, a short-term forecasting of wind speed will help in prior estimation of wind power generation availability for the grid and economic load dispatch.This paper present a comparative study of a Wind speed forecasting model using Artificial Neural Networks (ANN) with three different learning algorithms............

Abstract: This manuscript explores feeder reconfiguration in distribution networks and presents an efficient method to optimize the radial distribution system by means of simultaneous reconfiguration. Network Reconfiguration of radial distribution system is a significant way of altering the power flow through the lines. This assessment presents a modern method to solve the network reconfiguration problem with an objective of minimizing real power loss and improving the voltage profile in radial distribution system (RDS). A precise and load flow algorithm is applied and the objective...........

Abstract: In this paper functional approximations for the parameters of a DC machine are proposed. These nonlinear algebraic approximations are based on the experimental data that are obtained by carrying out several steady state and transient tests, besides, this method links mathematics and practical analysis of electromechanical systems, allowing students to improve their academic performance and comprehension by comparing estimated values with measured data. An excellent dynamic model results of combining the well known state space description and these parametric functional approximations. This augmented model provides reliable results even during demanding large-excursion transient conditions.

Abstract: This paper presents the mathematical modelling and simulation study of three phase squirrel cage induction machine. This is achieved, using the dot convention technique for magnetically coupled circuit applicable to circuit elements of electrical machines. When two loops (coils), with or without contacts between them affect each other through the magnetic field generated by one of them, they are said to be magnetically coupled when such loops are in a close proximity to each other, the magnetic flux caused by current in one coil links with the other loop, thereby inducing voltage in the later by mutual induction. Based on the notion of mutual induction, we then introduce the circuit element known as transformer............

Abstract: This paper proposes an optimization model for the selection of turbines in order to improve the power generation potential in a Hydro Power Plant. The thermal, electrical and mechanical stresses that occur over time on the turbine affect the efficiency of the generating unit. The mathematical formulation for this problem emanates a non-linear programming problem which is therefore solved using Particle Swarm Optimization and Differential Evolution optimizing techniques. These two algorithms are then compared and the results are validated in Dot Net.............

Abstract: A periodic GaAs wafer-bonded structure was used for nonlinear optical device. Results showed voids present at the bonded GaAs twin boundary. These voids were caused by natural topographical irregularities and surface contamination. Most contamination could be eliminated by sulfur passivation treatments. However, natural irregularities are inevitable. After bonding, two kinds of crystallites were formed at the bonded (001) interfacial voids: diamond-shaped and dendritic geometries. This paper discussed the dendrite growth models within the interfacial void regions.
