What can context do for web services?

Academia and industry, with the rapid development of information technologies, are adopting Web services due to their integration capabilities. Web services are being actively used for connecting business processes in business-to-business scenarios. The Web services community uses different languages for specifying Web services composition like BPEL and WSFL. The primary objective of these specification languages is to provide a high-level description of the composition process independent from any implementation details or concern. The need for a common semantics is intensified when Web services participate in the same composition. Web services, to reduce the limitations, must be context-aware, context is the information which characterizes the interactions between humans, applications and the environment. A possible solution to achieving a contextual semantic composition of Web services is built upon the semantic-value concept

Moving vs. inviting software agents

Servlet and applet strategies are discussed that can enhance the operations of software agents. In the servlet strategy, the flow takes place from the client to the server and in applet strategy the flow takes place from the server to the client. The state-of-the-art in developing complex systems revolves around software agent technologies. Software agents should be embedded with mechanisms that allow them to make the correct decision: either move or invite

Modeling and Control of a UPFC System Using Pole-Placement and Hinf Robust Control Techniques

This is an open access article distributed under Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International license (CC BY-NC-ND 4.0) https://creativecommons.org/licenses/by-nc-nd/4.0/FACTS (Flexible AC Transmission Systems) technology has now been accepted as a potential solution to the stability problem and load flow. The Unified Power Flow Controller (UPFC) is considered to be the most powerful and versatile among all FACTS devices. This paper presents the modeling and control of a UPFC system using pole-placement and H robust control techniques. A simulation study using Matlab/Simulink is presented to compare the performance of these control strategies and their robustness with respect to variations is the system parameters such as the inductance of the transmission line.Peer reviewe

Transformation de modèles de lignes de produits en environnement hétérogène

Article de 4 pages,INFORSID 14 LYONArticle soumis dans le cadre de La septième édition du Forum Jeunes Chercheurs qui était organisé à Lyon le 22 mai 2014, dans le cadre du 32e congrès INFORSID.National audienceLe domaine de l'ingénierie de ligne de produits est en cours de développement, dans un monde où la concurrence est de plus en plus rude et où les entreprises sont de plus en plus amenées à diversifier leurs gammes de produits. Les entreprises les plus compétitives et innovantes se dirigent vers ce nouveau paradigme, afin d'augmenter leurs productivités et diminuer le temps de réalisation du produit. L'identification des points variables et communs d'une ligne de produits dans un modèle est une approche clé dans l'ingénierie des lignes de produits et plus particulièrement pour la gestion d'éléments commun et variable. Le processus de développement d'une ligne de produits passe par plusieurs phases, chaque phase est réalisée par un outil différent, si bien que des incohérences peuvent avoir lieu. Pour assurer la bonne collaboration et la cohérence de ces outils, il est nécessaire de faire face aux problèmes d'interopérabilité de ces outils. Dans cet article nous considérons que la transformation du modèle est l'une des solutions clés d'interopérabilité

Designing shift calendar for mobile phone

At Nokia production site employee’s work is divided into three shifts, each of 8 hours, and each employee works just one of those shifts. There is a need for a shift calendar for, since scheduling the staff for specific shifts sets an expectation for both the company and employee. Scheduling also allows the employee to plan his/her free time and budget. This thesis shows how to design a Java application by using NetBens IDE targeting cell phones, creating a shift calendar application leads to use J2ME. Java Platform, Micro Edition, is a Java platform designed for embedded systems which offers two methods,the file connection API JSR75, and the chosen option the RMS which is an a Record aggregation formed into columns and rows. The development environments (IDE) used is the NetBeans version 6.9 used by many developer as it provides a built-in support for developing in Java, C, C++, XML, and HTML ,Two different platforms are available for Nokia devices ; series 40 which occupies the biggest number of phones on the market and the series 60 or the “symbians” used as platform for smart devices, S60 is currently amongst the most-used Smartphone platforms in the world. It was created by Nokia, who made the platform an open API. After determining the shift calendar application most important requirements and creating the architecture, this includes: making the main classes of this project, designing the flow of the application by using the visual mobile designer and append the RecordStore procedure to the project main and finally compiling and running the project. This study explains how to design a MIDlet capable to read in RecordStore note available in phone’s memory by using the development kit NetBeans IDE 6.9. The user can define his/her own shift by name, ok command and the definitions will be persistent in the phone and can be modified or deleted. The application then browses the current week shift schedule for the all shifts. The results are further discussed and developed at the production
