Service-oriented computing as a concept for providing interoperability and flexibility within heterogeneous environments has gained much attention within the last few years. Dynamically integrating external web services into enterprise applications requires automatic contracting between service requestors and providers and automatic

This paper begins with the presentation of a service classification with two dimensions - continuity of coproduction and mutual adaptability, which define the four-category service systems served as a new reference architecture of service system design. The purpose of iDesign

In this paper, a Service-Oriented Software Reengineering (SOSR) methodology is proposed for reengineering a legacy system into a service-oriented system. Although Service-Oriented Computing (SOC) enables a software developer to design loosely coupled software components and integrate them with other software

The ever growing complexity of Information System (IS) landscapes is a transparency and simplification challenge by its own. When business requirements frequently change or when technical innovations are frequently implemented, IS agility has to be aimed at in addition to

A modified strip-yield model has been developed to simulate the plasticity-induced crack closure under the constant amplitude (CA) and a single overload loading conditions. The paper focuses on the simulation of the near tip crack profiles and stress distributions during

We present a method for analysing a vendor's exposure to uncertainties in IT services. These uncertainties arise in project portfolios with projects whose value covaries with managerial decisions about firm strategy, technology standards and platforms to be used. Past research

Continuing exponential growth in the Information Technology (IT) outsourcing market implies a need to understand the negotiated Service Level Agreements (SLAs) that underlie the majority of those sourcing relationships. Knowledge of the negotiation processes that are associated with the development

Financial risk/return management requires high computational capabilities. It therefore seems to be a suitable application domain for service-oriented computing based on grid technologies. Due to on-demand access to a high amount of computational resources, calculations can be accelerated and resources

The paper presents a design technique for a fixed-structure PD robust controller of car active suspension systems. The design takes into consideration the uncertainty of system parameters, particularly tyre stiffness and body mass. Robustness is achieved by tuning the controller

Well-damped transient response of power systems signifies a vital control task. The paper presents a design methodology of an adaptive power system stabiliser (PSS) to achieve such task by targeting certain damping ratio and settling time. A standard simple-structure controller

This paper is concerned with an adaptive output tracking control (AOTC) for a class of uncertain discrete-time systems via sliding mode theory. It is assumed that the uncertain discrete-time systems are described by a state equation with mismatched uncertainties found

This paper is concerned with the input-to-state stability (ISS) problem for a class of neural networks with time-varying delay. Some criteria are proposed to guarantee ISS which also ensures the neural networks to be globally asymptotically stable by exploiting Lyapunov

Adaptive control by means of neural networks for non-linear dynamical systems is an open issue. For real world applications, practitioners have to pay attention to external disturbances, parameters uncertainty and measurement noise, as long as these factors will influence the

This paper studies the global robust practical output tracking problem using a dynamic output feedback controller (i.e., an output compensator) for a family of uncertain non-linear systems whose Jacobian linearisation may be unstabilisable and/or undetectable. It is shown that under

In this study, an enhanced back propagation (EBP) algorithm for estimating the parameters of non-linear rational models is presented to improve convergence rate. The effectiveness of the EBP algorithm is initially demonstrated by simulations.

outlines the background to it and the technological transformation occurring in, and necessary for, African countries. It then discusses the papers presented and concludes with a section on the way forward.

At this time of the year on campus, the gridiron starts its hibernation and the parquet begins to heat up. Whether you watch from the student section, nosebleeds, sports bar, or living room, SC's Brian Cox gives us his "starting

The BCS is in shambles again and SC's Wailele Sallas is getting tired of sorting through the rubble. The college basketball season has started and in March, 65 teams will be vying to be a true champion. Here are 65
