Quality of Service (QoS) management is critical for service-oriented enterprise architectures because services have different QoS characteristics, requesters have different requirements, and service interactions are decoupled. This paper proposes a QoS Management Architecture for dynamic processing of service- and flow-level quality attributes to support QoS requests and analyses in Web-service-oriented architectures. The architecture is implemented using Business Process Execution Language for Web Services (BPEL4WS), an interoperable integration model that facilitates automated process integration). The proposed approach extends BPEL4WS by integrating it with Web service-level agreements (WSLA) to support QoS and extending the BPEL4WS language to provide a new " " assertion that describes the location of a document's WSLA document. Under the proposed approach, quality attributes are defined, computed, and acted upon as dynamic characteristics of systems, with values constantly changing in operation The feasibility of the proposed approach is demonstrated using an illustrative travel reservation service flow example.
Web applications exhibit dynamic behaviour through such features as animation, rapidly changing presentations, and interactive forms. The growing complexity of web applications requires a rigorous modelling approach c...

This paper looks into how integrating on-line purchasing with inventory management system for distributed retail chain stores can automate and aid the process of decision-making in relation to on-line product sales and distribution. It extends the work done in [1], to include not only on-demand and automatic communication between the retail chain store's head office and point-of-sale (POS) outlets, but also to include on-line purchasing capabilities for home users. The application uses distributed databases to store information relevant to customers, products and product transactions at different geographical locations. The system is designed to facilitate the management process between the head office and the POS outlets: it aids top-level management to make the right business decisions in terms of the right products being distributed at the right location and at the right time, and also products ordered by home users to be sent by the right POS outlet, and it aids low-level employees to manage the daily business transactions of each POS outlet efficiently.

The study on speech recognition and understanding has been done for many years. In this paper, we propose a fully-connected hidden layer between the input and state nodes and the output. Besides that, we also investigate and show that this hidden layer makes the learning of complex classification tasks more efficient. We also investigate difference between LPCC and MFCC in feature extraction process. The aim of the study was to observe the difference of Arabic's alphabet like "alif" until "ya". The purpose of this research is to upgrade the people's knowledge and understanding on Arabic's alphabet or word by using Fully-Connected Recurrent Neural Network (FCRNN) and Backpropagation through Time (BPTT) learning algorithm. 6 speakers (a mixture of male and female) are trained in quiet environment. Neural Network is well-known as a technique that has the ability to classified nonlinear problem. Today, lots of researches have been done in applying Neural Network towards the solution of speech recognition [1] such as Arabic. The Arabic language offers a number of challenges for speech recognition [2]. Even though positive results have been obtained from the continuous study, research on minimizing the error rate is still gaining lots of attention. This research utilizes Recurrent Neural Network, one of Neural Network technique to observe the difference of alphabet "alif" until "ya".
We present an approach to embedding a formal method into Rational Unified Process (RUP). The purposes are: (a) to unify different views of UML. (b) to enhance UML with the formal method to improve the quality of softw...

The problem this paper addresses is that an architecture formed of software components can contain composition errors (introduced, for instance, as a result of the choice of a framework's parameters). The title "Erroneous architecture is a relative concept" is to emphasize that whether a composition error occurs in an architecture depends on the way the architecture is used in its environment. An important issue is finding a way to possibly statically verify that, for a given setup containing the architecture, no composition errors can occur in any run. The contribution of the paper is bringing an evidence that this can be done by employing behavior protocols and their consent operator.

Final year, group (capstone) projects in computing disciplines are often expected to fill multiple roles: in addition to allowing students to learn important domain-specific knowledge, they should reinforce computing and softwareengineering concepts and provide for the acquisition of transferable skills. For motivational and pedagogical reasons, it is clearly preferable that such projects respond to real needs, be those in research or industry. We describe two student projects based on a large repository of usage data and integrated into a course in Professional Computing. These projects fulfilled the objectives outlined above and were closely linked to the research of the first author. We suggest that similar projects based on large databases may offer a transferable paradigm for others to follow. Finally, we outline some important elements for a successful group project based on a large database. Copyright 2004 ACM.
