Every Speed Breaker Is A Source Of Power
Every Speed Breaker Is A Source Of Power
Abstract: Electricity in India, is a big problem which is faced by people who reside in the country. Electricity is the form of energy, Electricity is a basic part of nature and it is one of our most widely used forms of energy. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. Before electricity generation began slightly over 100 years ago, we use kerosene lamps, and rooms were warmed by wood-burning or coal burning stoves. Direct current (DC) electricity had been used in arc lights for outdoor lighting. In the late-1800s, Nikola Tesla pioneered the generation, transmission, and use of alternating current (AC) electricity, which can be transmitted over much greater distances than direct current. Generating electricity by speed breakers is innovative and useful concept. Researches show that the world has already had its enough Shares of its energy resources. Fossil fuels pollute the environment. Nuclear energy requires careful handling of both raw as well as waste material. The focus now is shifting more and more towards the renewable sources of energy, which are essentially, nonpolluting. Energy conservation is the cheapest new source of energy. The utilization of energy is an indication of the growth of a nation. One might conclude that to be materially rich and prosperous, a human being needs to consume more and more energy. And this paper is best source of energy that we get in day to day life. This paper is presenting the study of electricity generation through the speed breaker mechanism.
Key words: ac: alternating current, dc: direct current, generation, lead acid battery, speed breaker.

Anti-Corrosive Effect of Tridax Procumbens – Zn2+ System Controlling the Corrosion of Carbon Steel
Anti-Corrosive Effect of Tridax Procumbens – Zn2+ System Controlling the Corrosion of Carbon Steel
Abstract: The corrosion inhibition efficiency (IE) of an aqueous extract Tridax Procumbens(TP) in controlling the corrosion of carbon steel aqueous medium containing 60 ppm of chloride ions in absence and presence of Zn2+ has been studied by weight loss method. The formulation consisting of 1 ml of Tridax Procumbens extract and 150 ppm of Zn2+ offers 96% inhibition efficiency. The synergistic effect exists between Tridax Procumbens and Zn2+ system. Polarization study shows that the Tridax Procumbens – Zn2+ system function as a cathodic inhibitor. AC impedance spectra reveal that a protective film formed on the surface. The Adsorption equilibrium exhibited better fit to Langmuir isotherm than Freundlich isotherm. FTIR spectra reveal that the protective film consists of Fe2+-Tridax Procumbens and Zn(OH)2.

An Automated Tool for Optimization of FMS Scheduling With Meta Heuristic Approach
An Automated Tool for Optimization of FMS Scheduling With Meta Heuristic Approach
Abstract: The evolutions of manufacturing systems have reflected the need and requirement of the market which varies from time to time. Flexible manufacturing systems have contributed a lot to the development of efficient manufacturing process and production of variety of customized limited volume products as per the market demand based on customer needs. Scheduling of FMS is a crucial operation in maximizing throughput, reducing the wastages and increasing the overall efficiency of the manufacturing process. The dynamic nature of the Flexible Manufacturing Systems makes them unique and hence a generalized solution for scheduling is difficult to be abstracted. Any Solution for optimizing the scheduling should take in to account a multitude of parameters before proposing any solution. The primary objective of the proposed research is to design a tool to automate the optimization of scheduling process by searching for solution in the search spaces using Meta heuristic approaches. The research also validates the use of reward as means for optimizing the scheduling by including it as one of the parameters in the Combined Objective Function. A complex machining operations configured in a FMS having 6 Machines with 3 different setups manufacturing 3 different parts, each having 9 possible routes is used as test case to validate the proposed approach. Three different Meta Heuristic approaches like Genetic Algorithm (GA), Differential Evolution (DE), and Bacterial Foraging Optimization Algorithm (BFOA) are used to optimize the scheduling process. A Graphical User Interface is designed using Matlab to automate the entire approach.
Key words: Flexible Manufacturing System; Scheduling; MATLAB GUI Tool; Genetic Algorithm; Differential Evolution and Bacterial Foraging Optimization Algorithm

Low Power Dynamic Logic Ripple Carry Adder Using Footed Diode Domino Logic
Low Power Dynamic Logic Ripple Carry Adder Using Footed Diode Domino Logic
Abstract: In recent electronic devices power saving has more importance than any other thing. Dynamic logic circuits are one of the basic power efficient circuits which comes into picture when dealt with low power. Dynamic logic circuits operate mainly in two phases, namely Pre-charge and evaluate phase. Domino logic circuits are more power efficient and cooperatively faster circuits which operate on the above two phases. For extremely low power applications footed diode domino logic is applied. This paper mainly deals with design of Dynamic logic circuit design based on footed diode domino logic with reduction in power and leakage current. In this proposed circuit we put a diode on the foot of domino logic circuit which results in power reduction as compared to reported and conventional domino logic. We are using NMOS as a diode and due to this extra diode (NMOS), in pre-charge period leakage current reduce due to stacking effect. Approximately 32% of power is saved using footed diode domino logic. For Simulation we are using tanner tool at 180nm technology.
Key words: Fulladder, Footed diode domino logic, Pseudo dynamic logic, Ripple carry adder, Stacking effect

Modified Approach for Hiding Secret Data and Improving Data Embedding Capacity
Modified Approach for Hiding Secret Data and Improving Data Embedding Capacity
Abstract: Security of the secret information has been a challenge when the large amount of data is exchanged on the internet. A secure transfer of information can be very much achieved by steganography and Cryptography. Steganography is a tool for hiding information inside an image. Cryptography is a tool which provides encryption techniques for secure communication. In the traditional steganograhy techniques principle was either to replace a special part of the frequency components of the carrier image, or to replace all the least significant bits of a multi-valued image with the secret information. Our new steganography uses an image as the carrier data, and we embed secret information in the bit-planes of the carrier. This technique makes use of the characteristics of the human vision system whereby a human cannot perceive any shape information in a very complicated binary pattern. We can replace all of the ―noise-like‖ regions in the bit-planes of the carrier image with secret data without deteriorating the image quality.
Key words: Bit Plane, BPCS, Hybrid Cryptography, LSB, Modified BPCS, Steganography.

Influence of Wall Position on Flow Characteristics of an Impinging Jet
Influence of Wall Position on Flow Characteristics of an Impinging Jet
Abstract: The study intends physical insight into heterogeneous phenomena of efflux from a small opening impinging on a surface. The work aims at understanding the role of wall location and orientation on flow characteristics of an impinging jet. Experiments were performed on an existing cascade tunnel with flow ejected at a velocity of 37 m/s from a small opening of (30 cm × 9 cm) and corresponding flow features were analyzed. Results show that outside the core region, the flow experiences a monotonic reduction with increase in distance along streamline and radial direction. The orientation of wall is more efficient in bringing substantial change when placed closer to the exit (low velocity losses). The wall orientation primarily governs the chances of strong flow deflection or back flow losses. Wall placed far away from exit results in diminishing returns with a critical value beyond which the flow characteristics become insensitive of wall orientation.
Key words: Efflux, shear interaction, vortices, wall jets, wall orientation, wall location.

Modifying Authentication Techniques in Mobile Communication Systems
Modifying Authentication Techniques in Mobile Communication Systems
Abstract: Milenage algorithm applies the block cipher Rijnadael (AES) with 128 bit key and 128 bit block size. This algorithm is used in the 3GPP authentication and key generation functions (f1, f1*, f2, f3, f4, f5 and f5*) for mobile communication systems (GSM/UMTS/LTE). In this paper a modification of Milenage algorithm is proposed through a dynamic change of S-box in AES depending on secret key. To get a new secret key for every authentication process we add the random number (RAND) transmitted from the authentication center (AUC) to the contents of the fixed stored secret key (Ki) and thus the initialization of the AES will be different each new authentication process . For every change in secret key a new S-box is derived from the standard one by permuting its rows and columns with the help of a new designed PN sequence generator. A complete simulation of modified Milenage and PN sequence generator is done using Microcontroller (PIC18F452). security analysis is applied using Avalanche test to compare between the original and modified Milenage . Tests proved that the modified algorithm is more secure than the original one due to the dynamic behavior of S-box with every change of the secret key and immunity against linear and differential cryptanalysis using Avalanche tests. This makes the modified Milenage more suitable for the applications of authentication techniques specially for mobile communication systems.

The proposed controllers consist of PI controller act as voltage controller and DC offset canceller. The
experimental result derived by using the MATLAB software.
