KM-SORE: Knowledge Management for Service Oriented Requirements Engineering

Service-oriented Software Engineering is a new style for creating software using reusable services which are available over the web. The biggest challenge in this process is to discover and select the appropriate services that match system requirements. Currently, none of the proposed approach has been accepted by research community as a standard. There is very little empirical work available that addresses requirements engineering in service oriented paradigm. The aim of this study is to propose a framework for requirements engineering in SOSE. The framework is based on a new idea, that integrating Knowledge Management in Service Oriented development would improve requirement engineering phase as it does for traditional software engineering. The framework is developed in the light of the issues and challenges identified by published literature and the feedback of practitioners and researchers working on service oriented projects

Wireless Communication in Process Control Loop: Requirements Analysis, Industry Practices and Experimental Evaluation

Wireless communication is already used in process automation for process monitoring. The next stage of implementation of wireless technology in industrial applications is for process control. The need for wireless networked control systems has evolved because of the necessity for extensibility, mobility, modularity, fast deployment, and reduced installation and maintenance cost. These benefits are only applicable given that the wireless network of choice can meet the strict requirements of process control applications, such as latency. In this regard, this paper is an effort towards identifying current industry practices related to implementing process control over a wireless link and evaluates the suitability of ISA100.11a network for use in process control through experiments

Systematic reviews in requirements engineering: A tertiary study

© 2014 IEEE. There has been an increasing interest in conducting Systematic Literature Reviews (SLR) among Requirements Engineering (RE) researchers in recent years. However, so far there have been no tertiary studies conducted to provide a comprehensive overview of these published SLR in RE. In this paper we present a tertiary study of SLR that focus solely on RE related topics by following the guidelines of Evidence Based Software Engineering. We have conducted both automated search of major online sources and manual search of the RE and SLR related conferences and journals. Our tertiary study has identified 53 distinct systematic reviews published from 2006 to 2014 and reported in 64 publications. We have assessed the resulting SLR for their quality, and coverage of specific RE related topics thus identifying some gaps. We have observed that the quality of SLR in RE has been decreasing over the recent years. There is a strong need to replicate some of these SLR to increase the reliability of their results for future RE research

Methodologies and tools for OSS: current state of the practice

Over the years, the Open Source Software (OSS) development has matured and strengthened, building on some established methodologies and tools. An understanding of the current state of the practice, however, is still lacking. This paper presents the results of a survey of the OSS developer community with a view to gain insight of peer review, testing and release management practices, along with the current tool sets used for testing, debugging and, build and release management. Such an insight is important to appreciate the obstacles to overcome to introduce certification and more rigour into the development process. It is hoped that the results of this survey will initiate a useful discussion and allow the community to identify further process improvement opportunities for producing better quality software

What makes service oriented requirements engineering challenging? A qualitative study

The focus of Service Oriented Software Development (SOSD) is to develop software by integrating reusable services to lower the required cost, time and effort of development and increase reusability, agility, quality and customer satisfaction. It has been recognised in the literature that SOSD faces various challenges especially in requirements engineering (RE). The objective of this study is to investigate these challenges of Service Oriented RE (SORE) from practitioners' perspectives in order to gain a deeper understanding of the related issues and to reveal potential gaps between research and practice in SORE. They present a qualitative study of the challenges and issues in SORE. The data were collected by conducting interviews with practitioners working in IT companies in Sydney, who have had substantial experience with service oriented software projects. The authors findings reveal that most of the challenges of SORE are similar to those that are faced during RE in traditional or component-based software development. According to the practitioners, the research and practice has made some advances in the technical direction but the human related issues in SORE have not been addressed adequately. © The Institution of Engineering and Technology 2014

Evidence in Requirements Engineering: A Systematic Literature Review Protocol

Requirements Engineering (RE) is recognized as one of the critical phases in software development. RE has its own journals and conferences where lots of work has been published. As the area is maturing, increasingly large numbers of empirically supported studies have been reported in RE. There is a need to synthesize evidence based RE literature. We plan to systematically investigate evidence based RE studies to see and report state of the art in evidence based RE reported research. This paper aims at providing a systematic literature review (SLR) protocol to describe a process for synthesizing the empirically supported work in the area of RE that will eventually present a state of the art of the field. This SLR intends to not only summarize the empirical data regarding RE but will also be helpful for various practitioners in this field to find out areas of RE rich in terms of tools, techniques, frameworks, models and guidelines to aid in their work. It will also facilitate RE researchers to identify knowledge gaps to recognize needs and chances for future research directions in this field

Enhanced production of subtilisin of Pyrococcus furiosus expressed in Escherichia coli using autoinducing medium

A subtilisin gene identified in the reported genome sequence of Pyrococcus furiosus was amplified and inserted in pET-22b(+) vector to produce the recombinant plasmid pET-SB. Escherichia coli BL-21 (DE3)CodonPlus was transformed with this plasmid and the enzyme was expressed up to 30% of the total cell protein on induction with IPTG. The expressed protein appeared at a position corresponding to ~20 kDaon SDS-PAGE as compared to theoretical molecular mass of 17.6 kDa. This aberrant electrophoresis mobility could be due to specific amino acid composition of the protein. Auto-induction with lactose also produced a similar level of expression but the total amount of the enzyme produced was 2.4 foldgreater than that when produced with IPTG induction. This was due to a higher cell density obtainable in the auto-inducing medium. The enzyme expressed in the insoluble state could be partially refolded after denaturation with urea at high pH. This study reports for the first time high-level expression ofsubtilisin of P. furiosus in E. coli using an auto-inducing medium

Direct Exponent and Scalar Multiplication Classes of an MDS Matrix

An MDS matrix is an important building block adopted by different algorithms that provides diffusion and therefore, has been an area of active research. In this paper, we present an idea of direct exponent and direct square of a matrix. We prove that direct square of an MDS matrix results in an MDS matrix whereas direct exponent may not be an MDS matrix. We also delineate direct exponent class and scalar multiplication class of an MDS matrix and determine the number of elements in these classes. In the end, we discuss the standing of design properties of a cryptographic primitive by replacing MDS matrix by dynamic one

GPU accelerated shake and rattle algorithms for systems with holonomic constraints

The dynamic of complex fluid can be described by including viscoelastic stress tensor into the equation of Non-Newtonian fluid. Different models are used to evaluate the stress tensor at various levels, with the multi-scale model being the most effective
