In the last four decades many software reliability growth model based on non-homogeneous Poisson process (NHPP) have been developed which incorporates testing effort function. However, the previous models are quite helpful for software engineers/ developers and commonly applicable in the industries and research institution. Still more testing-effort functions are required to incorporate into software reliability growth model. In this paper, we develop delayed S-shaped software reliability growth model with imperfect debugging which incorporates new modified Weibull testing–effort function (NMWTEF). We estimate the testing effort model parameters by least square and S-shaped software reliability growth parameters by maximum likelihood estimation techniques. We also present confidence interval of the software reliability growth parame...

It's no secret that poorly understood user requirements and uncontrolled scope creep to many software project failures. Many of the application development professionals buy wrong tools for the wrong reasons. To avoid purchasing the more complex and expensive tool, the organization needs to be realistic about the particular problem for which they opt. Software development organizations are improving the methods, they use to gather, analyze, trace, document, prioritize and manage their requirements. This paper considers four leading Requirements Management tools; Analyst Pro, CORE, Cradle and Caliber RM, the focus is to select the appropriate tool according to their capabilities and customers need.

As development of object oriented software is raising security problem is also increasing. The software security focuses on the effort and cost spent in lateral phases is much greater than the initial phase of software development process. It is understandable that most of the software is not well designed with respect to security concern. Therefore, to secure the software after deployment is not only costlier but difficult too. The aim of the paper is to study better way of design consideration to secure the object oriented software and discuss the tools which are required for the secure software development. This paper will provide an opportunity to understand the requirement for developing a technique at design phase.

Both type of learning have importance in different scenario. Not one of them can fulfill whole requirement individually. Synchronous training is done in real-time with a live instructor facilitating the training. Everyone logs in at a set time and can communicate directly with the instructor and with each other. It lasts for a set amount of time- from a single session to several weeks, months or even years. Asynchronous is e-learning in the more traditional sense of the word. It involves self-paced learning, CD-ROM-based, Network-based, Intranet-based or Internet-based. It may include access to instructors through on-line bulletin boards, on-line discussion groups and e-mail.

Renewable lightweight cryptography algorithms are developing to beat the constraints of traditional cryptosystem, which provide tradeoff among cipher sort, attack immune, key size, plaintext length, and performance. The implementation of LWC algorithms is carried out on retaining in the mind that it will be implemented in minimal power consumption, fewer area requirement and also enough efficiency so it turns out to be ideal for such a resource confine devices such as RFID tags and wireless sensor node. In this, we are trying to emerge with frequent LWC algorithms which are grouped into stream cipher, block cipher, and hybrid model, and also reveal them, at the last a comparison is conducted on the effective parameters.

From the knowledge point of view this huge amount of data is of great importance and it requires super large computing powers to analyze process and derive meaningful conclusions. The term big data is applicable to all the information that can no longer be handled using traditional means. It is interesting to see this challenge in terms of big data being faced by the organizations today. In this paper we have focused on various dimensions of Big Data and we have proposed a model for the management and analysis of Big Data.

In order to protect data from unintended users and to achieve a desirable level of security, several cryptographic algorithms based on various technology have been proposed. Linear Feedback Shift Register (LFSR) may play an important role in the design of such cryptographic algorithms. LFSR based cryptographic algorithms are often lightweight in nature and are more suitable for resource constraining devices. In this paper we present a detailed analysis of LFSR and design of LFSR to implement cryptographic algorithms.

Information Retrieval, Information Extraction, Question Answering, Text Mining, Machine Translation etc. Researchers defined WSD as to identify the actual meaning of a word based on the context in which it occurs. Whereas in linguistic, context is defined as the text in which a word or passage appears and which helps ascertain its meaning. Hence, context of a word depends on different part of speech (POS) of a sentence i.e. Noun, Verb, pronoun, adjective and adverb. This paper proposes a novel approach for context based word sense disambiguation using soft sense disambiguation, map-reduce, knowledge based multimodal algorithm and WordNet.

Whereas this type of networks does not have any fixed routers or any pre-exist infrastructure. Also, every node is capable of movement and can be connected to other nodes dynamically. Therefore, the network topology will be changed frequently and unpredictably according to continuous interaction between nodes that simultaneously affect network topology in the basis of dynamic ad-hoc nature. This factor puts routing operation in critical area of research under mobile ad-hoc network field due to highly dynamic environment. To adapt this nature, MANETs demand new routing strategies to occupy these challenges. Thereafter, huge amount of protocols are proposed to argue with ad-hoc requirements. Thus, it is quite difficult to specify which protocols perform better under different mobile ad-hoc scenarios. This paper examines the prominent routing protocols that are designed for mob...

It plays a crucial role in various natural language processing (NLP) applications viz. Information Retrieval, Information Extraction, Question Answering, Text Mining, Machine Translation etc. Besides single modal measures, multimodal or combination of measures also available in previous work. In this paper a multimodal WSD measure is proposed, that integrates the benefits of Wu & Palmer, Lesk and most frequent sense (MFS) measures. Experimental results on datasets Senseval-2 and Senseval-3 proves the proposed model Bokhari-WSM performs better than previous knowledge based lexical measures.

Owing to the good statistical properties, large period and low implementation costs, LFSR have achieved wide acceptance in developing stream ciphers. This paper intends to present a self-contained and comprehensive analysis of linear feedback shift registers and their application in stream ciphers. This research focuses on analyzing the mechanism of an LFSR, the two implementation variations and various properties of LFSR, which play a vital role in stream cipher design. In the last section of this paper, we address the security aspect of LFSR based stream ciphers and different techniques to enhance it.
