Software Evolution: An Empirical Study of Mozilla Firefox
-Anita Ganpati,Dr. Arvind Kalia,Dr. Hardeep Singh Abstract
The changes to software are inevitable as new requirements emerge with the use of the software. The change is necessary in terms of correcting errors, improving the performance and reliability of the system. The changes corresponding to corrective, preventive, adaptive and perfective maintenance leads to evolution of software. Software product is an evolving entity which starts with an initial implementation of a set of requirements and from then onwards software undergoes frequent modifications generally for the purpose of increasing its functionality, performance or in order to adapt to a changed environment. Software evolution refers to the phenomenon of software change and growth. The environment where software has to operate changes over time and software itself must adapt to this changing environment. The software does not change by itself but changed by the development and maintenance teams. In this study the evolution of Mozilla Firefox Open Source Software (OSS) was analysed empirically on latest fifty versions. The applicability of Lehman’s Law of software evolution was investigated on Mozilla Firefox using different software metrics. The Resource Standard Metrics (RSM) software metrics tool was used to get the values of the size and complexity measures of the software. It is evident from the results of the study that the evolution of the Mozilla Firefox for the latest fifty versions was in accordance with Lehman’s laws of continuing change, increasing complexity, continuing growth and declining quality

Performance Overview of Image Fusion Techniques -Sachin A. Sonawane,Shashikant S. Patil Abstract
In Multi-focus image fusion, multiple partially defocused images are combined into a new image with all the interested objects focused. Various techniques of Multi-focus image fusion already exist and still researchers in the area are introducing new algorithms for improved results. Different parameters like PSNR, Entropy can be used to evaluate the performance of these algorithms. In this paper we compute and evaluate performance measures for some of the techniques like Discrete Wavelet Transform, Simple Average Method, and Select Maximum etc. The comparative statement based on the evaluation of experimental results certainly helps to select a particular fusion method. Generally performance measures are dependent on defocused area of the image and size of input images is the major consideration in computation. Artificially defocused images are utilized for experiment purpose.

Modeling and Simulation of Data Encryption Standard Algorithm on FPGA -Shivangi Vajpayee, Rajesh Rai Abstract
In this paper we demonstrate an efficient and compact reconfigurable hardware implementation of the Data Encryption Standard (DES) algorithm. Our design was implemented on FPGA of device VirtexEXCV400e. As a strategy to reduce the associated design critical path, we utilized a parallel structure that allowed us to compute all the eight DES S-boxes simultaneously. Our DES round design achieved a data encryption/decryption rate of 274 Mbits/s occupying only 117 CLB slices. These results are quite competitive when compared with other reported reconfigurable hardware implementations of DES.

Robust Watermarking Scheme for Quality Loss of Data -Chirag Sharma,Anshu Sharma,Shilpa Sharma Abstract
Watermarking is a technique of embedding hidden and unnoticeable signal into an image in the form of text and image so that even if unauthorized person tries to access and use it illegally, he could be caught on the basis of Copyright Protection and Ownership Identification. There are 2 methods that can be followed to embed a watermark in an image: Visible Watermarking and Invisible Watermarking. Visible Watermarking is used to display the watermark inside the image so that intruder can’t use it unless he has copyrights for that image. Invisible Watermarking hides watermark from the intruder so that he can be caught on the basis of Copyright Protection. Quality loss is the major issue in Watermarking. Embedding watermark inside the image can degrade the quality of watermarked image. In this paper we are going to present a technique that can reduce less amount of quality after the insertion of watermark in both visible and invisible watermarking methods. The implementation of Visible and Invisible Watermarking methods is realized with the help of MATLAB. Results are taken by calculation of PSNR values of Watermarked images after applying various attacks on Watermarked image to check the efficiency of Watermarking
Keywords: Discrete Wavelet Transformation (DWT), Invisible Watermarking, Visible Watermarking, Information Hiding, Copyright Protection, Quality loss. |

Prediction tool for Crime Analysis -Priyanka Pitale,Asha Ambhaikar Abstract
Regression is one of a powerful tool for predicting the future values based on previous data sets. The use of prediction in crime analysis can make crime free region.. The proposed technique can predict those regions which are sensitive to criminal activities like theft, murder, rape, Anti-social behaviour, Domestic violence etc. The scheme uses the data sets taken from the local police stations and can be used to predict the number of criminal activities in future. The data will then supplied with other factors like population, month and year to the regression model which will predict the future value for the criminal activities. This predicted number of activities will indicate that the region is high sensitive or low sensitive. If the predicted number will be high then the region is high sensitive and if low then the region is low sensitive

Fingerprint Image Enhancement using Wavelet over Gabor filters -T. Vidhya,T. K. Thivakaran Abstract
Fingerprint identification is one of the most popular biometric technologies and is used in criminal investigations, commercial applications, and so on. The performance of a fingerprint image-matching algorithm depends heavily on the quality of the input fingerprint images. It is very important to acquire good quality images but in practice a significant percentage of acquired images is of poor quality due to some environmental factors or user’s body condition. Therefore, an image enhancement algorithm is necessary to increase the performance of the minutiae extraction algorithm. The traditional approach is based on Gabor filter, which is the most common approach used in the fingerprint image enhancement. The proposed approach deals with the wavelet denoising which enhances the fingerprint image by reducing noise and selecting threshold values by the computation of discrete wavelet transform, and thus comparing the performance of the traditional and proposed approach.

An Efficient IRIS Recognition System -Prashant Sarode Abstract
The human iris, an annular part between the pupil and the white sclera is emerging as a highly reliable biometric trait for personal identification. Although the area of the iris is small it has enormous pattern variability which makes it unique for every person and hence leads to high reliability. Modern cameras that are used for acquiring iris are less intrusive compared to earlier iris scanning devices and public awareness of system reliability and difficulty to circumvent is developing. An iris has a mesh like texture to it, with numerous overlays and patterns. Basically, iris recognition system comprises of four main modules: Image Acquisition, Preprocessing, Feature Extraction and Pattern Matching. Firstly an image containing the users eye is captured by the system. Then the image is preprocessed. Thirdly, features representing the iris patterns are extracted. Finally, decision is made by means of matching

Automated Inspection of Defects in Glass by proper Color space selection and Segmentation Technique of Digital Image processing -Nishu,Sunil Agrawal Abstract
Glass defects which result into poor quality are a major reason of embarrassment for manufacturers. It is an extremely tedious process to manually inspect very large size glasses. The manual inspection process is slow, time-consuming and prone to human error. Automatic inspection systems using image processing can overcome many of these disadvantages and offer manufacturers an opportunity to significantly improve quality and reduce costs. In this paper we propose an evaluation system for detection of various glass defects like scratches, inclusions, surface defects etc. The process involves the color space selection and a segmentation technique often used in medical imaging has been tested for detection of various defects in glass. The color space conversion helps in the selection of best color space for quantifying the visibility of the defects while the segmentation algorithm involves the use of contour method based on intensity inhomogeneities.

Image Encryption using Blowfish and Genetic Algorithm -Varsha Nemade,Prof.R.B.Wagh Abstract
Today in the world of Internet information security is more important. Encryption is the technique by which readable information is converted into unreadable form. This is the useful technique to avoid unauthorized access. In the area of multimedia, an image has become important medium of communication, they are used in many fields such as medical science, military; they are stored or transfer through network, security of such image data is important. Text encryption algorithms which have been already developed are not suitable for the image encryption, because image containing large amount of data means it contains number of pixels. Image encryption techniques decrease the correlation among the pixels, so that we will get lower correlation among the pixel and get the encrypted image. In this paper one of the method proposed for image encryption in which first blowfish encryption is applied and then on the result chaotic function is applied to generate number of encrypted images after that genetic algorithm is applied to get the optimized result.

A Noval Approach of AODV for Stability and Energy Efficient Routing for MANET using IPV6 -Shival Chadda,Mritunjay Kumar Rai Abstract
In a mobile ad hoc network (MANET), the topology of the network may change rapidly and unexpectedly due to mobility of nodes. Thus, setting up routes that meet high reliability is a very challenging issue. Another important problem in the MANETs is the energy consumption of nodes. This paper presents experiments on the performance and stability of the AODV protocol (Ad hoc On-demand Distance Vector protocol) in multi-hop ad hoc networks. We study the network performance such as throughput, delivery ratio, and end-to end delay. After this experimental study of the problems that may arise in this type of communication and its origins, we conclude that better performance is possible with the modification of some of the protocol´s parameters, without modifying the protocol algorithm. Applying these changes, experimental tests show an improvement in the performance of the protocol.

A Proposed Service Broker Policy for Data Center Selection in Cloud Environment with Implementation -Dhaval Limbani, Bhavesh Oza Abstract
Cloud Services may be offered as public or private or combined. There is the demand of timely, repeatable, and controllable methodologies for evaluation of algorithms, applications, and policies before actual development of cloud products. Using simulation, we can study the behavior of them in cloud environment. Cloud-Analyst, the Cloud-Sim based tool, is useful to model and analyze cloud computing environment and applications. The simulator uses different algorithms (Service Broker Algorithms, Load balancing algorithms etc) and generates report as per configuration. With the help of simulation report, we can modify the cloud environment as per requirement. The service proximity based routing policy used in the simulator selects data center from the earliest region to route the user requests. When there is the situation to select one data center from those with same region, the policy selects data-center randomly without considering cost-effectiveness or other parameters. We have proposed the extended service proximity based routing policy. Using proposed policy, we can have cost effective routing of user requests to the data center than in the original one. And thus, some of the research issues related to cost can be explored

Logistic Model Tree With Modified AIC -Mitesh J. Thakkar, Neha J. Thakkar, Dr. J.S.Shah Abstract
Logistic Model Trees have been shown to be very accurate and compact classifiers. Their greatest disadvantage is the computational complexity of inducing the logistic regression models in the tree. This issue is addressed by using the modified AIC criterion instead of crossvalidation to prevent overfitting these models. In addition, to fill the missing values, mean and mode are used class wise for numeric and nominal attributes respectively. The comparison of training time and accuracy of the new induction process with the original one on various datasets and show that the training time often decreases and the classification accuracy also increase slightly.
