Venkateshwaran.T

Abstract: One of the Major problems which we face today is agriculture. If the agriculture is done in a large scale the monitoring of large farms becomes a tedious process, so a computational method which monitors the nutrient content of the different parts of the farm land is required to enhance the crop yield of the farm land. so my aim is to instantaneously monitor the farm land continuously using a new technology called smart dust and send the information for processing and if there is a lack of a particular nutrient then automatically the required amount of the nutrient is mixed with the water and then irrigated , and if the farm lacks in water then it is sensed by the smart dust and information is transmitted , then the pump is automatically switched on. By using this technology the farm can be monitored 360 degrees which will then result in increased crop yield.

An imperceptible blind image watermarking scheme for image authentication using DNA encoding and multi-resolution wavelet decomposition
Pearl Antonette Mendez ||, Rithu James

Abstract: Digital storage, transmission and manipulation of video signals and still images exhibited a tremendous growth in the last few years, mainly due to the expansion of computer networks and the introduction of multimedia technologies to the information market. Copyright protection techniques are in great demand due to the widespread illegal copying and communication of digital media. One way to protect images against illegal recordings and retransmissions is to embed a signal, called digital signature or copyright label or watermark, that completely characterizes the person who applied it and, therefore, marks it as being his intellectual property. Various watermarking methods have been proposed lately for digital images. Wavelet-based embedding techniques gained a lot of attention since they provide the perfect balance between imperceptibility and robustness. In this project, we introduce an algorithm for hiding the complement of a DNA-encoded watermark data into the 3rd level resolution of the wavelet decomposition of a true colour image. It applies a quantization operation on the sorted detail coefficients for an enhanced invisible embedding

Ibrahim, S.A ||, Tijjani, A.M,

Abstract: This paper focused on developing an enhancement of the vehicle antitheft security systems via a Phone call. It is designed to improve vehicle security and accessibility since it can be used to monitor and control other devices in the vehicle. The system will manipulate a mobile phone to send commands in form of DTMF signals to the vehicle. It utilizes an embedded system design with Dual Tone Multi Frequency (DTMF) and a GSM to monitor and safeguard a car. Upon activation, it automatically demobilizes the car by disconnecting the ignition key supply from the car battery. This makes it impossible for anybody to starts the car. The vehicle is controlled by a mobile phone that makes a call to the GSM mobile phone attached or incorporated into the vehicle. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call. This tone is called "dual-tone multiple-frequency‟ (DTMF) tone. The vehicle perceives this DTMF tone with the help of the phone stacked into the vehicle. The received tone is processed by the microcontroller with the help of DTMF decoder. The decoder decodes the DTMF tone into its equivalent binary digit and this binary number is sent to the microcontroller. The microcontroller is programmed to take a decision for any given input and outputs. Upon receiving a code, the microcontroller will then carryout appropriate task based on the way it was programmed. The microcontroller is programmed to carry out the task of disconnecting the ignition or fuel system of the vehicle, or to control another device in the vehicle

Essam Hendawi

Abstract: Selective harmonics can be eliminated by controlling the inverter switches at optimized switching angles in single phase dc-ac inverters. These switching angles are estimated by solving a set of nonlinear equations. This paper presents a novel technique for solving these equations based on secant method. The proposed algorithm simplifies the numerical solution of the nonlinear equations, solves them fast and achieves convergence of solution at different starting vector of angles. The proposed method is applied with different modulation index and different number of equations, i.e. different number of switching angles to achieve the elimination of certain harmonics. High performance of the inverter is validated through simulation results.

J. Mallesh, H.Sanghamesh, m.Narsimulu

Abstract:At a peripheral milling machining, positioning of the workpiece generally has deviations from its nominal position in the sense of small displacements and orientations. These differences generally depend on:Geometrical defects of the machining assembly;contact defects of the workpiece on the machining assembly;Deformation caused by dynamic cutting forces, for positioning and clamping. Indeed, the evolution cutting orces acting on the workpiece during machining causes a critical vibrational behavior of the part that generates small dynamic displacements interaction « workpiece-mounting » causing instabilities layring and a generation of geometric imperfections during machining. When the defect is too large by-the geometrical and dimensional specifications required, we must minimize vibration of the room, by acting on the optimal configuration of the locations of iso-static support clamps, but also cutting condition.

K. Babu Reddy, K. Harinath Reddy, P. Venkata Ramanaiah

Abstract:The beneficial effects of DG mainly depend on its location and size. The non optimal placement of multiple DGs will lead to increase the losses in the system and also its cost of generation. Therefore, the selection of optimal location and size of the DG plays a key role to maintain the constant voltage profile and reliability of existing system effectively before it is connected to the power grid. In this paper, a method to determine the optimal locations of DG is proposed by considering power loss. Also, their optimal sizes are determined by using kalman filter algorithm. It also analysis the system cost of generation before and after placement of DG. The proposed KFA based approach is to be tested on standard IEEE-30 bus system. Index Terms: Distributed Generation, Optimal location, Optimal Size, Power loss and Kalman filter algorithm.

Abstract:It is a challenging task in a network-on-chip to design an on-chip switch/router to dynamically support guaranteed traffic permutation in multiprocessor system- on-chip under the constraints of power, timing, area, and time-to-market. The proposed network implies a pipelined circuit-switching approach combined with a dynamic path-setup scheme under a multistage network topology. The dynamic path-setup under probing mechanism defines runtime path arrangement for arbitrary traffic permutations. The circuit-switching approach offers a guarantee of permuted data and its compact overhead enables the benefit of stacking multiple networks.

Novel Three-Level Converter forPower-Factor-Correction and Connected To DC Drive
B Padma, J Ranga

Abstract:Harmonic pollution and low power factor in power systems caused by power converters have been of great concern. To overcome these problems several converter topologies using advanced semiconductor devices and control schemes have been proposed. In this paper a new three-level ac–dc single-stage converter that can operate with standard phase-shift pulse width modulation is proposed.The ac–dc power supplies with transformer isolation are typically implemented with some sort of input power factor correction (PFC) to comply with harmonic standards such as IEC 1000-3-2. There are three techniques to satisfy these standards. One of them is adding passive filter elements to the traditional passive diode rectifier/LC filter input combination; the resulting converter is very bulky and heavy due to the size of the low-frequency inductors and capacitors. In this paper, the operation of the converter is explained, and its feasibility is confirmed with experimental results obtained from a prototype converter. Finally, the efficiency of the new converter is compared with that of the converter shown..

M Sandeep,J Ranga

Abstract:This paper presents successful application of a space vector pulse width amplitude modulation (SVPWAM) for buck –boost voltage source inverter. It is a standard PWM technique to utilize the DC-AC power conversion, for a voltage source inverter, in this technique the switching losses is reduced by 87%, as compared to conventional sinusoidal pulse width amplitude modulation (SPWM) method. In this case power density increased by a factor of 2 to 3. In addition, it is also verified that the output harmonic distortions of SVPWAM is lower than SPWM. The switching power loss is reduced by 90% compared with the conventional SPWM inverter system. Hence to obtain the good voltage transfer and reduced switching losses SVPWAM is used. As a result, SVPWAM is used to make the buck–boost inverter suitable for applications that require high efficiency, high power density, high temperature, and low cost, such as EV motor drive or engine starter/synchronous machines. In this work, a buck boost voltage source inverter using space vector modulation strategy has been modeled and simulated. Simulation results are obtained using MATLAB/Simulink environment for effectiveness of the study..

Design of New Rv Multilevel Inverter Topology For Induction Motor Applications
J Ranga, Abhinav

Abstract:Multilevel inverters have been widely accepted for high-power high-voltage applications. Their performance is highly superior to that of conventional two-level inverters due to reduced harmonic distortion, lower electromagnetic interference, and higher dc link voltages. However, it has some disadvantages such as increased number of components, complex pulse width modulation control method, and voltage-balancing problem. In this project, a new topology with a reversing-voltage component is proposed to improve the multilevel performance by compensating the disadvantages mentioned. This topology requires fewer components compared to existing inverters (particularly in higher levels) and requires fewer carrier signals and gate drives. Therefore, the overall cost and complexity are greatly reduced particularly for higher output voltage levels. Finally, a prototype of the seven-level proposed topology is built and tested to show the performance of the inverter by experimental results.
