As the continuous development of computer network technology and rapid popularization of Internet application, ecommerce and e-government businesses are used more and more widely. However, at the time that these applications bring great convenience to our work and lives, they also bring increasingly serious security problems. Identity authentication is an important method to ensure safety of various e-commerce activities, e-government business information and internet information. Certificate based digital signature authentication and password authentication are most common at present. But traditional password authentication with basic mode of user name and password authentication faces many security problems . Network Security & Cryptography is a concept to protect network and data transmission over wireless network. Data Security is the main aspect of secure data transmission over unreliable network. Data Security is a challenging issue of data communications today that touches many areas including secure communication channel, strong data encryption technique and trusted third party to maintain the database. The rapid development in information technology, the secure transmission of confidential data herewith gets a great deal of attention. The conventional methods of encryption can only maintain the data security. The information could be accessed by the unauthorized user for malicious purpose.

An Efficient Ensemble Based Classification Techniques for Medical Diagnosis

G. Ravi Kumar, Venkata Sheshanna Kongara, Dr. G.A Ramachandra · August 2013 · pp. 05-09

Building accurate and efficient classifiers for Medical databases is one of the essential tasks of data mining and machine learning research. Building effective classification systems is one of the central tasks of data mining. One of the most active areas of research in supervised machine learning has been to study methods for constructing good ensembles of learners. This paper aims to establish an accurate ensemble classification model for Medical prediction, in order to make full use of the invaluable information in clinical data, especially which is usually ignored by most of the existing methods when they aim for high prediction accuracies. This paper presents a comparison among the different ensemble classifiers on the database of Wisconsin Breast Cancer (WBC) and Diabetes data sets. In this experiment, we compare ensemble classification techniques in Weka software and comparison results show that Random forest has higher prediction accuracy than those methods. Different methods for breast cancer detection are explored and their accuracies are compared with these results, we infer that the Random forest are more suitable in handling the ensemble classification problem of Medical prediction, and we recommend the use of these approaches in similar ensemble classification problems.

Ms. Nitika Agarwal, Ms. Neha Singh · August 2013 · pp. 10-16

This paper presents the hybrid digital image watermarking technique. Taking the advantages of discrete wavelet Transform (DWT), the host image is decomposed into its significant components. The D component of Singular value decomposition (SVD) of approximate sub image of host image is taken. Watermark image is embedded in D component using Dither Quantization. The proposed algorithm uses advantages of SVD and DWT technique. The algorithm is more secure and robust to various attacks, viz., Gaussian noise, salt & pepper noise, speckle noise, Poisson noise, JPEG compression, median filtering, scaling and rotation. Superior experiment results are obtained from proposed algorithm in terms of Bit Error Rate (BER) and Peak signal to noise ratio (PSNR). Page(s): 10-16 Date of Publication: August 2013

Fault Diagnosis of Analog Circuits Using dc Approach and Neural Networks

Vaibhav Sharma, Vijay Maheshwari · August 2013 · pp. 17-25

Fault diagnosis of circuit is a major problem of theory of circuit networks and especially with the development of electronic technique at high speed, the increasing complexity of electronic equipment and altitudinal integration of electronic circuit, it is of importance in particular. Testing and diagnosis of electronic devices are fundamental topics in the development and maintenance of safe and reliable complex systems. In both cases, the attention is focused on the detection of faults affecting a subsystem whose appearance generally impairs the global system safety and performance. In a complete fault diagnosis procedure, fault detection and isolation must be carried out together; the effectiveness of the procedure depends on fault detection and isolation performance as well as the complexity of the test phase. While there are established techniques to obtain an automatic diagnosis for a digital circuit, the development of an effective automated diagnosis tool for analog or mixed circuits is still an open research field. For more than two decades, the subject of fault location in analog circuits has been of interest to researchers in circuits and systems. In recent years this interest has intensified and a number of promising results has emerged. Page(s): 17-25 Date of Publication: August 2013

Determination and evaluation of a Harmonics in Adjustable Speed Drives

Amit Wankhade, Anil Kumar Chaudhary, C.Veeresh · August 2013 · pp. 42-47

A large diversity of solutions exists to reduce the harmonic emission of the 6-pulse Adjustable Speed Drive in order to fulfill the requirements of the international harmonic standards. Among them, new types of advanced harmonic filters recently gained an increased attention due to their good harmonic reduction performance at the same time with small costs and engineering. In the event that such filters are used to replace existing solutions, the assessment of the harmonic performance before commissioning is a necessity. This assessment is possible by using software tools to compare the performance of different topologies. This paper presents a method to integrate the model of the filter into an existing harmonic calculation toolbox dedicated for harmonic analysis on the 6-pulse converter. The results are linked together into a practical PC software toolbox for harmonic estimation. By using a combination of a pre-stored database and new interpolation techniques the toolbox can provide the harmonic data on real applications allowing comparisons between different mitigation solutions.

In Linear polynomial phenomenon; the interpolating function is only continuous and not differentiable everywhere. So a cubic spline introduced. In this paper, we have a presented the cubic spline interpolation method for zooming in an image. The fundamental idea behind cubic spline interpolation is based on the engineer’s tool Used to draw smooth curves through a number of points [2]. The cubic spline algorithm is programmed in MATLAB as m-file. Firstly, according to the zooming intensity, sufficient zeroes are inserted between each pixel and then those zeroes are replaced by the respective values generated by the m-file. Finally a zoomed in image in constructed. Page(s): 67-72 Date of Publication: August 2013

A Survey of Router Design Algorithms for NoC Platform and their Performance Analysis

Priyanka Sao, Rekha Agrawal · August 2013 · pp. 73-76

Network on Chip (NoC) is an approach to designing the communication subsystem between IP cores in a System on a Chip (SoC). NoC improves the scalability of SoCs, and the power efficiency of complex SoCs compared to other designs. The purpose of NOC is to solve the choke point in communication and the clock problem from architecture. Each route in NOC includes some routers, and it takes a few clock periods by passing a router. When the network is in congestion, the package transmission will produce much more time delay. So adopting a appropriate routing algorithm to get the balance between the time delay and throughput rate becomes the key problem.This paper basically review of XY routing algorithm for 2D torus topology of Network on chip architecture for constant bit rate (CBR) random traffic in NIRGAM simulator to reduce the average latency per packet and increase average throughput.

Active Power Filter with Fast PI Controller using matlab/simulink

Dipak Badgujar, Anil Kumar Chaudhary, C.Veeresh · August 2013 · pp. 77-84

In a modern power system, due to broader applications of nonlinear loads such as power electronic equipment or arc furnaces, the degree of waveform distorted is increasingly serious now. These loads may cause poor power factors, lead to voltage notch, or result in a high degree of harmonics. The instantaneous response of the active power filter (APF) is very important while compensating rapidly varying balanced, unbalanced and nonlinear loads. Any change in the load affects the dc-link voltage directly. The proper operation of APF requires variation of the dc-link voltage within the prescribed limits. Conventionally, a proportional-integral (PI) controller is used to maintain the dc-link voltage to the reference value. It uses deviation of the capacitor voltage from its reference value as its input. However, the transient response of the conventional PI dc-link voltage controller is slow. In this paper, a fast-acting dc-link voltage controller based on the energy of a dc-link capacitor is proposed. Mathematical equations are given to compute the gains of the conventional controller based on fast-acting dc-link voltage controllers to achieve similar fast transient response. The detailed simulations are carried out on MATLAB environment to validate the proposed controller. Page(s): 77-84 Date of Publication: August 2013

Pawan Kumar, Dr. Shiv Ram Singh Jhajharia · August 2013 · pp. 85-87

Employee retention means how to Retain Employees as some private company offer a competitive benefits package, including health and life insurance and a retirement plan some provide employees financial incentives such as raises, bonuses and stock options ,consider hiring a human-resources manager if your company is nearing 100 employees. Make sure employees know what's expected of them and how they can grow within your company, refers to the ability of an organization to retain its employees. Hiring employees is just a start to creating a strong work force. Next, you have to keep them. High employee turnover costs business owners in time and productivity. – Offer a competitive benefits package that fits your employees’ needs. Providing health insurance, life insurance and a retirement-savings plan is essential in retaining employees. But other perks, such as flextime and the option of telecommuting, go a long way to show employees you are willing to accommodate their outside lives. – Provide some small perks. Free bagels on Fridays and dry-cleaning pickup and delivery may seem insignificant to you, but if they help employees better manage their lives, they’ll appreciate it and may be more likely to stick around.

Comparative Study of Data Hiding in Encrypted Image using lossless and lossy Compression

Dr. Vivek Sharma, Mr. Hariom C. Agnihotri. · August 2013 · pp. 100-104

We propose an information hiding technique which based on pixels’ block. We used pixels contractive relation to hide the information that we want to embed. The characteristic of our method is that to use pixels contractive relation to assist lossy compression process in reducing the image size. There exists many hiding techniques, but most of the techniques cannot tolerate the destruction of lossy compression. Compression will speed up the transmission of the image with the hiding data.We achieve something others cannot do, to implement compression into the transmission of images in order to speed up the process. Data hiding is the process of hiding piece of information into a cover media such as image, video, audio, etc. Various data hiding algorithm has been proposed for different applications, for example, it can be used for covert communication, image authentication, copyright, copy control in DVD, traitor tracing, data integrity, etc. Among these data hiding techniques, robust lossless data hiding has received increasing interest. Robust data hiding is the ability to extract the secret data correctly after compression or any other incidental alteration has been applied to the stego-image. In lossless data hiding the original image is recovered after extraction of data from the stego image. It has been successfully applied to many images, including aerial, texture, miscellaneous, standard images and medical images. Specifically, it has been successfully applied to authenticate lossless compressed JPEG2000 images, followed by possible transcoding. It is expected that this new robust lossless data hiding algorithm can be readily applied in the medical field, law enforcement, remote sensing and other areas, where the recovery of original images is desired. With the fast progression of data exchange in electronic way, information security is becoming more important in data storage and transmission. While storing and transmitting multimedia data are not easy and they need large storage devices and high bandwidth network systems. Compression and encryption technologies are important to the efficient solving of network bandwidth and security issues. This paper focus on dual approach of compression and security where compression is achieved through lossless algorithm (either Huffman coding or LZW) according to size and type of image data and compressed data is encrypted using traditional DES Algorithm.
