Knowledge modeling and management are helping tools to learn the software organizations. The traditional Requirements engineering practices are based upon the interaction of stakeholders which causes iteratively changes in requirements and difficulties in communication and understanding problem domain etc. So, to resolve such issues we use knowledge based techniques to support the RE practices as well as software development process. Our technique is based on two prospective, theoretical and practical implementations. In this paper, we described the need of knowledge management in software engineering and then proposed a model based on knowledge management to support the software development process. To verify our results, we used controlled experiment approach. We have implemented our model, and verify results by using and without using proposed knowledge based RE process. Our resultant proposed model can save the overall cost and time of requirement engineering process as well as software development.展开更多

The sustainable development indicators are grouped into 10 subject categories： socioeconomic development, sustainable consumption and production, social inclusion, demographic changes, public health, climate change and energy, sustainable transport, natural resources, global partnership and finally good governance. In this paper, the authors examined a number of researches and compared the methods they used in order to determine the advantages and disadvantages of each method. The methods used a large number of different indicators. The comparison of the indicators could be made through mathematical models and also through theoretical approach.展开更多

Even though many MDE-oriented approaches, languages and tools have been developed in the recent past, there is no standard that concretely defines a specific sequence of steps to obtain a functional software system from a model. Thus, the existing approaches present numerous differences among themselves, because each one handles the problems inherent to software development in its own way. This paper presents and discusses a reference model for the comparative study of current MDE approaches in the scope of web-application development. This reference model focuses on relevant aspects such as modeling language scope (domain, business-logic, user-interface), usage of patterns, separation of concerns, model transformations, tool support, and deployment details like web-platform independence and traditional programming required. The ultimate goal of this paper is to determine the aspects that will be of greater importance in future web-oriented MDE languages.展开更多

The tragic deaths of some 4000 persons, as a direct result of this epidemic, have also been accompanied by serious economic disruption to one of the world’s poorest countries, amounting to a loss of over USD 1 billion (20 per cent of annual Gross Domestic Product, GDP). Based on recent work undertaken by the New Partnership for Africa’s Development (NEPAD), an assessment was made of the potential contribution of one of the country’s major natural resource sectors—fisheries—to future economic recovery. It was confirmed that the fish resources of Sierra Leone have an estimated capitalised economic value of USD 735 million, and could potentially make an increased contribution to GDP under suitable conditions, over and above the current estimated level of 10 per cent. However, our results also show that with an overall “readiness assessment” score of 41/100, the sector is unlikely to realise its full potential unless a number of specific areas are addressed (based on analysis valid up to January 2016). These include an improvement in fisheries economic assessment, the upgrading of the fisheries governance and management framework, and the establishment of a fisheries development strategy and implementation plan to channel future investments and interventions in an appropriate sequence. Particular attention should be given early on to an increase in the quality and capacity of both public and private sector organisations relevant to roles and functions within a general process of fisheries sector reform. Finally, the fisheries policy evaluation approach used here is novel. While it has been applied to Sierra Leone for the intrinsic interest of that case, this demonstration also shows that it could be applied elsewhere in the future when reviewing fisheries policy.展开更多

As a part of this effort most of the previously proposed program control-flow complexity metrics are evaluated. It is observed that most of these metrics are inherently limited in distinguishing capability. However, the concept of composite metrics is potentially useful for the development of a practical metrics. This paper presents a methodology for the develop- ment of a practical composite metric using statistical techniques. The proposed metric differs from all previous metrics in 2 ways: (1) It is based on an overall structural analysis of a given program in deeper and broader context. It captures various structural measurements taken from all existing structural levels; (2) It unifies a set of 19 important structural metrics. The compositing model of these metrics is based on statistical techniques rather than on an arbitrary method. Experinces with the pro- posed metric clearly indicate that it distinguishes different structures better than the previous metrics.展开更多
