It is essential for any software to evolve so as to be used for large time period. It is necessitate to evolve software in order to do changes like adaptive, corrective, preventive maintenance In this paper we are presenting the results of study conducted on different versions of an open source software i.e. JStock. We calculated Object Oriented Metrics and investigated the changes in the measu...

In this paper we present results from an investigation on correlations between subjective and objective evaluation metrics for young people using a conversational agent. The subjective evaluation metrics capture users’ experiences of different aspects of conversations with a virtual agent while the objective evaluation metrics are based on an analysis of the actual conversation between the user...

We introduced a new approach to describe Java software as graph, where nodes represent a Java file called compilation unit (CU) and an edges represent a relations between them. The software system is characterized by the degree distribution of the graph properties, like in-or-out links, as well as by the distribution of Chidamber and Kemerer metrics computed on its CUs. Every CU can be related ...

Inheritance is an important aspect of object-oriented paradigm during software development. Inheritance supports the class hierarchy design and relation between classes and inheritance also has an impact on the complexity of software. Complexity of software increases the testing and maintenance efforts. So researchers and developer always try to reduce the software complexity because low softwa...

Software defects rediscovered by a large number of customers affect various stakeholders and may: 1) hint at gaps in a software manufacturer’s Quality Assurance (QA) processes, 2) lead to an overload of a software manufacturer’s support and maintenance teams, and 3) consume customers’ resources, leading to a loss of reputation and a decrease in sales. Quantifying risk associated with the redisc...

Inspired by the eye diagram in classical radio frequency (RF) based communications, the MOL-Eye diagram is proposed for the performance evaluation of a molecular signal within the context of molecular communication. Utilizing various features of this diagram, three new metrics for the performance evaluation of a molecular signal, namely the maximum eye height, standard deviation of received mol...

An important problem is that of finding matching pairs of records from heterogeneous databases, while maintaining privacy of the database parties. As we have shown in earlier work, distance metrics are a useful tool for record-linkage in many domains, and thus secure computation of distance metrics is quite important for secure record-linkage. In this paper, we consider the computation of a num...

objective: this paper tries to analyse and visualize the co-authorship network of institutions in 1351 papers published in 7 knowledge and information science journals in iran from 1387 through 1391.methodology: in this paper, we use scientometric and social network analysis to study the collaboration network of institutions. overall structure of the network was investigated using a few macro-l...

Research backbone networks like GÉANT2 and the National Research and Education Networks are used by a variety of scientists and research projects. These users and the network engineers operating the networks would like to get access to network performance metrics to optimise their use of the network and to troubleshoot performance degradations, when they happen. A variety of tools for performin...

in this paper, we are going to study the g-natural metrics on the tangent bundle of finslermanifolds. we concentrate on the complex and kählerian and hermitian structures associated with finslermanifolds via g-natural metrics. we prove that the almost complex structure induced by this metric is acomplex structure on tangent bundle if and only if the finsler metric is of scalar flag curvature. t...
