Abstract : CONTEXT – Global Software Development (GSD) is a modern software engineering paradigm adopted by many client organisations in developed countries to get high quality product at low cost in low wage countries. Production of high quality software is considered as one of the key factor in the rapid growth of GSD. However GSD projects have put new challenges to practitioners and researchers. In order to address these challenges Software Quality Metrics (SQMs) are frequently used in organisations to fabricate high quality products. OBJECTIVE - The objective of this SLR protocol is to identify and assess strengths and weaknesses of the existing SQMs used in GSD to assist vendor organisations in choosing appropriate SQMs for measuring software quality. METHOD – Systematic Literature Review (SLR) will be used for the identification of the existing SQMs in GSD. SLR is based on a structured protocol, and is therefore, different from ordinary review. EXPECTED OUTCOME – We have developed the SLR protocol and are currently in process of its implementation. The expected outcomes of this review will be the identification of different SQMs for GSD along with their SWOT analysis to assist vendor organisations in choosing appropriate SQMs at the right time to produce a high quality product.

CONTXEXT:-Software outsourcing partnership (SOP) is a relationship between client and vendor organizations for shared goals. A SOP is different than ordinary outsourcing contractual relationship. Usually a successful outsourcing relationship may lead to outsourcing partnership.
OBJECTIVE:-The objective of this research is to identify factors via systematic literature review (SLR), that are significant to be developed by outsourcing vendor organization which lead them to convert existing outsourcing contractual relationship into outsourcing partnership with client organization.
METHOD: -SLR will be used for the aforementioned objective. SLR is based on a structured protocol and is more thorough than ordinary review.
EXPECTED OUTCOMES: - We have developed a SLR protocol for the SOP. The anticipated outcome of this review will be a list of critical success factors (CSFs) and critical risks (CRs) which can have a positive or a negative role in building or converting the existing outsourcing relationship into outsourcing partnership.

Abstract: Noises are the unwanted information in an image, so they should be removed before further processing. Existing methods consider histogram based analysis which is globally varied one. A modified statistical measured based automatic noise type recognition technique is proposed in this paper. This has 2 phases including training phase and testing phase. The key role involves deduction of noise samples using filters like wiener, lee, median and extracts the statistical measures like kurtosis and skewness from samples. Kurtosis and skewness values exhibit behavior based on noise type. By using the statistical information and trained data we can classify the type of noise. Finally the noise type is identified and corresponding filter is applied. Thus noise eliminated image would give the desirable results during further processing. Experimental results show that the method is capable of accurately classifying the types of noise.

Abstract: Shadow detection and removal from color images is invariably significant for image processing. Existing methods use illuminant invariant methods to detect and minimize shadow which is computationally expensive. RGB color space based shadow removal method is existing one which blurs shadow edges. The performance of this existing method mainly depends on structuring element. To overcome all disadvantages, this paper is aimed to utilize RGB color space with modified structuring element. The effect of shadow is decreased on pixel while increasing values of 3 color channels of pixel using modified approach. Experiment results show that proposed system is computationally inexpensive and can robustly remove shadow from complex images.

Abstract : CONTEXT – Global Software Development (GSD) is an emerging trend to perform software development activities across national boundaries. Despite of the benefits gained from GSD, there are certain challenges associated with it. Amongst these challenges one of the critical challenge, which has comparatively little attention in software engineering research community, is the integration of products and components developed by different teams at different locations.
OBJECTIVE – The objective of this paper is to design SLR protocol to identify the challenges associated with software/product integration based on project size and product type in GSD environment from vendor's perspective and to identify the factors to be addressed before, during and after the integration process by the vendor organisations.
METHODOLOGY – We will conduct a Systematic Literature Review (SLR) to identify the challenges and factors mentioned above. SLR is different from ordinary review because it is comparatively unbiased and is based on a predefined protocol.
EXPECTED OUTCOME – The expected outcome of the review will be identification of challenges and factors for software integration in GSD. The identified factors through the review will lead us to develop a Software Integration Model (SIM) that will assist vendors to appropriately address the challenges and factors associated with software/product integration in GSD for different sized and types of projects and products.

Abstract: Cloud computing security (sometimes referred to simply as "cloud security") is an evolving sub-domain of Computer security, Network security and, more broadly, Information security It refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing. Cloud security is not to be confused with security software offerings that are "cloud-based" (a.k.a. security-as-a-service).There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software, platform, or infrastructure as a service via the cloud) and security issues faced by their customers. In most cases, the provider must ensure that their infrastructure is secure and that their clients' data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information. The extensive use of virtualization in implementing cloud infrastructure brings unique security concerns for customers or tenants of a public cloud service. Virtualization alters the relationship between the OS and underlying hardware - be it computing, storage or even networking.

Abstract: We consider a hybrid wireless sensor network with static and mobile nodes. Static sensors monitor the environment and report events occurring in the sensing field. Mobile sensors are then dispatched to visit these event locations to conduct more advanced analysis. The sensing field may contain obstacles of any shape and size. A big challenge is how to dispatch the mobile sensor to the event location without colliding with any obstacles and in a shortest path. Therefore the objective of the paper is to dispatch the mobile sensor to the event location in a hybrid wireless sensor network in the presence of obstacles. Our solution proposes a simple way to dispatch the mobile sensor to the event location in the presence of obstacle. This paper contributes in defining a more general and easiest dispatch solution in the presence of obstacle.
