Edge detection plays a vital role in medical imaging applications such as MRI segmentation. Magnetic resonance imaging (MRI) is an imaging technique used in medical science to diagnose tumors of the brain by producing high quality images of the inside of the human body, by using various edge detectors. There exists many edge detector but still, need for research is felt in order to enhance their performance...
With the growth of the Internet, web applications are becoming very popular in the user communities. However, the presence of security vulnerabilities in the source code of these applications is raising cyber crime rate rapidly. It is required to detect and mitigate these vulnerabilities before their exploitation in the execution environment. Recently, Open Web Application Security Project (OWASP)...
Recently, machine-learning based vulnerability prediction models are gaining popularity in web security space, as these models provide a simple and efficient way to handle web application security issues. Existing state-of-art Cross-Site Scripting (XSS) vulnerability prediction approaches do not consider the context of the user-input in output-statement, which is very important to identify context-sensitive...
In this paper, a robust stability analysis approach is proposed for a discrete-time system with time-varying delay. The uncertainty is assumed to be norm-bounded. The developed criterion is terms of Linear Matrix Inequality (LMI) based on Lyapunov-Krasovskii approach. To obtain such criterion matrix variable approach is used. To demonstrate the proposed criterion some examples are considered.
This paper presents a novel optimization based technique to synthesize uniformly excited time-modulated unequally spaced linear arrays (UE-TMUSLAs) using firefly algorithm (FA). The relatively newly developed algorithm has been employed to accomplish the optimum set of inter elements spacings and on time duration (OTD) of the switches that are connected to the array elements to time-modulate the static...
A bare PCB is PCB without any component mounted on it. PCB plays a significant role on the performance of various electronic products. So, there is requirement of fast & quantitative assessment. Since the manual inspection system is unreliable and time consuming, automatic optical inspection method is used. This paper presents an algorithm mainly having two parts, one is image enhancement and...
ELearning, as an efficient and flexible method of learning, has drawn more and more attention from researchers and practitioners in the past decades. The use of ELearning system is spreading rapidly in today's learning process and it is drastically changing the field of current scenario to get the information. This article describes the framework and methods which will be exploited to disseminate...
Libraries are repositories of knowledge and the tremendous growth in digital resources has forced library professionals to use various information technology tools to manage and render services to the users. To achieve greater efficiency in the rapidly changing environment, libraries are increasingly looking for new paradigms to deliver services to users on their desktops. Library portals play a crucial...
Synthesis of low side lobe power pattern with controlled harmonic radiation in time-modulated antenna arrays (TMAA) is a population based, stochastic optimization method. Due to the random nature, the initial population of such method greatly influences the convergence characteristics of the optimization tools. In this paper, a study on the effect of the convergence characteristics of the differential...
Today in the era of wireless technology, everything seems to be possible. One of the wireless techniques that made the things easier is Zig-Bee technology. Zig-Bee is a wireless personal area network (WPAN) based on IEEE 802.15.4 standard to provide communication in short distance with low data rate in low cost. Zig-Bee 802.15.4 WPANs are made up of end devices, routers and a co-ordinator by using...
In this advanced generation of science and technologies, nothing seems to be impossible. The new emerging technologies have made every dream possible. This paper deals with Zig-Bee wireless technique. The Zig-Bee wireless personal area networks (WPANs) are ad-hoc low power networks that are basically applicable in short range distance in low cost. These networks are made up of several to large number...
A new fuzzy c-means clustering with non-extensive entropy regularization is proposed in this paper. The purpose of entropy regularization is to form approximate solutions of singular problems in the maximum entropy framework. The non-extensive entropy with Gaussian gain is generally used for identifying non-uniform probability densities as in regular texture patterns. It is thus well suited for regularizing...
Next generation cellular network is expected to overcome the issues like demand for high data rates, better network coverage, energy, and spectrally efficient system. In this paper, femto based heterogeneous cellular network (HCN) with cognitive approach is considered to address these issues. This paper investigates two tier cognitive based HCN for overlay, underlay, and mixed overlay-underlay spectrum...
Femto cells a.k.a. Low Power Nodes (LPNs) are deployed to improve indoor data rates as well as reduce traffic load on macro Base Stations (BSs) in 4G/LTE cellular networks. Indoor UEs getting high SNR (Signal-to-Noise Ratio) can experience good throughput, but SNR decreases at faster rate due to obstacles, present along the communication path. Hence, efficient placement of Femtos in enterprise buildings...
Involvement of wireless technologies in Industrial environment obligates the identification and modeling of present noise and interferences. Such extraneous signals exhibit self similar structures, repetitive patterns and hence cannot be modeled conventionally as white noise. In this paper, we therefore propose to model them as color noise. Patterns of several colors of industrial noise are generated...
With introduction of online transaction the fraudulent activities through World Wide Web have increased rapidly. It's not only affecting common people but also making them lose huge amount of money. Online transaction basically takes place between merchant and customer, and in this case neither customer nor the card needs to be present at the time of transaction so merchant does not know that whether...
Particle Swarm Optimization is a stochastic optimization algorithm, but it converges to local optima, especially in some complex issue like optimization of high dimension function. It has been observed that the traditional particle swarm optimization algorithms converses rapidly during the initial stage of a search, but in course of time becomes steady considerable and gets trapped in a local optima...
Currently, dependence on web applications is increasing rapidly for social communication, health services, financial transactions and many other purposes. Unfortunately, the presence of cross-site scripting vulnerabilities in these applications allows malicious user to steals sensitive information, install malware, and performs various malicious operations. Researchers proposed various approaches...
Microarray dataset may contain a huge number of insignificant and irrelevant features that might lead to loss of useful information. The classes with both high relevance and having high significance feature sets are generally preferred for selecting the features, which determines the sample classification into their respective classes. This property has gained a lot of significance among the researchers...
Spectral efficiency (SE) and energy efficiency (EE) are the critical challenges for the next generation cellular network (NGCN). Small cells deployment and cognitive radio which facilitates efficient utilization of radio spectrum are the promising techniques for evolution of the NGCN.
