This paper describes E-TCP, an evolutionary computation approach for TCP. It is designed to avoid heavy congested areas by using an evolutionary path adaptation of the outgoing packets. E-TCP is evaluated through simulations using ns2. E-TCP delivers a significant performance improvement for bulk data transfers. Copyright 2008 ACM.

Requirements engineers have been eliciting requirements using various techniques, methods and tools. This paper proposes a mobile application tool to facilitate requirements elicitation process supporting story-based technique. Conventional devices and tools used in RE process in order to gather information mostly are deploying desktop computers or notebooks. Owing to their size and less mobility feature, they are usually not brought to the work place of the stakeholders. The advancing capabilities of mobile devices and mobile tools can significantly contribute to the facilitation of RE activities. A "story based mobile application for requirements engineering process (SMAREP)" is a mobile based application tool to help requirements engineers and analysts in eliciting, documenting and validating information from stakeholders.

The focus of this paper is a construction of better knowledge base in case-based classifier system. Our knowledge base structure is based on concept lattice where rules are built from its subconcept-superconcept relation. Since the lattice can only be constructed from inputs with binary attributes, descriptive and numeric attributes must be transformed to binary attributes. In this paper, we propose the transformation of numeric attributes to descriptive attributes using fuzzy set theory. We experiment on benchmark data sets, Car and Iris, to determine the performance in term of number of rules used and classification precision. The results show that trend of accuracy is proportional to the size of learning inputs. The number of rules used is relatively small compared with size of training data. Our case-based classifier produces very promising results in practice and can classify the new problem more accurate than traditional classifiers. Copyright 2008 ACM.

Producing software that is adaptable to the rapid environmental changes and the dynamic nature of the business life-cycle is extensively becoming a topical issue in the software evolution. In this context, change propagation (CP) process is one of the critical parts in the software change management. Traditional strategies have projected more complex ways, resulting to substantial failures and risks. This paper presents an investigation and highlights on the desired criteria to provide better means to simplify the complicated CP tasks. The evaluation results may be used as a foundation in improving CP approaches that provide significant challenges in software evolution.

Much as software is very useful as a driving force of physical machine in assisting many aspects of human endeavor, it is also often accomplished with delicate aspect especially when correct specification and quality are not met. Ranging from less critical applications (such as payroll), to highly sophisticated application (such as health care system) as well as mission critical applications (such as space mission), failures in the functionality of these systems are often accompanied by disproportionate heavy losses to the respective users. In addition, industrial application is performance-intensive and cannot afford to fail. In this paper, our novel open onions ontology was presented which approaches software development from a layered point of view, the open source approach as an alternative methodology for industrial application development was proposed. Various issues involved in industrial applications were reviewed, the current industrial development methodologies were discussed and possibilities of adopting open source were explored.

In today's Web environment, many enterprises decide to implement and publish their applications on the Internet using Web services technology. In many cases, a single service is not sufficient to fulfill the user's request. To solve this problem, services should be combined together. Therefore, composition of Web services is one of the recent critical issues. A number of approaches have been presented, to tackle this problem. In this paper, we categorize these approaches into four categories (workflow-based, AI-planning based, syntactic-based, and semantic-based). Then, we compare these approaches based on some criteria (like QoS, scalability, and correctness). Investigation of that classification will help researchers who are working on service composition to deliver more applicable solutions.

A Time-Action-Lock (TAL) is a state of a real-time system at which neither time can progress nor an action can occur. Behzad and Kozo presented a TAL-freeness detection method based on the geometry of Timed Automata. It is realized by means of translating the problem to Rational Presburger Sentences that has its drawback of efficiency. In this paper, the authors present an algebraic approach for TAL-freeness detection, which can detect the TAL-freeness directly. Detailed correctness proofs and performance analysis are provided.
