The vision of ubiquitous communication is driven by increasing user mobility and the need to collaborate. Mobile collaborative applications, such as mobile audio/video conferences, collaborative writing, social networks, and mobile gaming, are already important parts of human interaction. In this paper, we present the uBeeMe platform that supports the development of cooperative applications for...

This study suggests how an order-receiving company can avoid disclosing schedule information on unit tasks to the order-placing company when carrying out a collaborative project on the value chain in an order-oriented industry. Specifically, it suggests methods for keeping schedule information confidential, and categorizes potential situations by inter-task dependency. Lastly, an approach to se...

The noticeable advance in the area of computer technology has paved the way for the invention of powerful mobile devices. However, limited storage, short battery life, and relatively low computational power define the major problems of such devices. Due to the ever increasing computational requirements, such devices may fail to process needed tasks under certain constraints. One of the proposed...

Development in construction industry is leading to involve complexities in engineering systems; whereas it also required to its sustainability towards social, environmental, and economical aspects. Experts with requisite background and expertise are involved in order to integrate knowledge in achieving whole criteria through design process. Collaborative design is needed in order to attain opti...

Scientific workflows have become an important instrument for domain scientists to synergistically integrate distributed computations and data to accelerate scientific discoveries. Existing scientific workflow tools, however, only support single scientists to compose scientific workflows in a desktop application. Nowadays, many scientific research projects are becoming increasingly larger scale,...

In this paper, we explore the learning that occurred in two types of collaborative learning environments in a seventh grade life sciences classroom: an intra-group environment and an intergroup environment. Students used both types of collaboration tools, each tuned to the needs of the task they were doing within or across groups. We found that the learning outcomes in the two collaborative set...

A collaborative retrieval, based on the concept of sharing between users, is increasingly used to facilitate the research and to satisfy the needs. In this context, we suggest to improve the performance of collaborative research, taking account of the annotations as a new source of information describing the documents. In our contribution, we suggest to apply the relevance feedback to expand th...

This article pursues two tasks. The first is to clarify the value and productivity of Williams’s Keywords: a vocabulary culture society (first edition 1976, second expanded 1983a) for project Cultural Studies. clarification helped, I argue, by reading it alongside Vološinov’s Marxism philosophy language (published in Russian 1929, translated into English 1973). related task speculative developm...

This article presents our prototype MASET (Multi Agents System for E-Tutoring Learners engaged in online collaborative work). MASET that we propose is a system which basically aims to help tutors in monitoring the collaborative work of students and their various interactions. The evaluation of such interactions by the tutor is based on the results provided by the automatic analysis of the inter...
