Software has laid a strong influence on all occupations. The key challenge of an IT industry is to engineer a software product with minimum post deployment defects. Software Engineering approaches help engineers to develop quality software within the scheduled time, cost, and resources in a systematic manner. In order to incorporate effective defect management strategies using software engineering discipline needs a complete and widespread knowledge of various aspects of defects. The position of this paper is to provide a pattern analysis of post production defects based on empirical observations made on several main frame projects developed in one of the leading software industries. Inferences thus obtained from this investigation indicate the existence of show stopper severity defects and their associated root cause. This awareness enables the developing team to reduce the residual defects and improve the pre production quality. It further aids the attainment of total customer satisfaction. © Springer International Publishing Switzerland 2015.

Wireless Ad Hoc networks are popular for critical applications due to characteristics such as simplicity, low cost, and no central administration. These networks are infrastructure less and not comparable with traditional networks with infrastructure. Infrastructure networks are configured, managed, and administrated centrally. As no centralized administration is present, self-organization is used in wireless networks to create virtual topologies and communication among nodes of network. In this paper, we present a survey of strategies used by different researchers for achieving self-organization in wireless Ad Hoc networks and make the network robust, secure, and energy efficient. © Springer India 2016.

Ever since the introduction of computers, technological advancement has taken an exponential form. Thus, development of software which attains total customer satisfaction is one of the mandatory needs of any software industry. Delivery of defect free software is one of the primary requisites to achieve the aforementioned objective. In order to comprehend defect facets, it is essential to have knowledge of defect pattern at various phases of software development. This paper therefore provides a comprehensive analysis of occurrence of defect pattern which are obtained through a case study carried out in one of the sampled leading software industry. This empirical investigation is a throw light for the project personnel to formulate effective strategies towards reduction of defect occurrences and thereby improve quality, productivity and sustainability of the software products. © Springer International Publishing Switzerland 2015.

The fast development in the field of optoelectronics necessitates the search for new and efficient NLO crystal materials, which can be used for optoelectronics applications, such as optical computing, optical data storage, optical communication and electro optic shutters. For the fulfilment of these applications, crystals of calcium tartrate were grown by a simple gel technique using single diffusion method. The optimum growth conditions were established by various parameters such as pH of gel solution, gel concentration, gel setting time, concentration of reactants etc. Crystals having different morphologies and habits were obtained. The crystal size is about 5 x 4 x 3 mm. Calcium tartrate crystals are found to be orthorhombic with lattice parameters: a = 9.45900 Å, b = 6.46400Å, c = 5.39600Å. The crystals were characterized by using XRD, TGA and DTA techniques.

Restoration of digital images contaminated by impulse noise is still a challenging job for researchers. A novel filter based on neuro-fuzzy system and dilation rule has been proposed, which works well in presence of high density noise. Adaptive Neuro-Fuzzy Inference System (ANFIS) has been used to detect the impulse noise, and dilation rule has been used to remove the detected corrupted pixel. ANFIS helps to preserve the fine details of the image and a little modified dilation rule gives the estimated value for pixel replacement. Experimental results show the effectiveness of the proposed restoration method by qualitative and quantitative analysis. © 2014 IEEE.
