The continuing evolution of business needs and technology makes Web applications more demanding in terms of development, usability and interactivity of their user interfaces. The complexity and diversity of these applications emerges the need of flexibility and combining operations with existing models to create other new, more complex models. As more complex models are used, the importance of transformations...
The article provides a theoretical basis of multi-agent recursive cognitive architectures as a distributed intelligent system of decision-making and control of an ambient intelligence system. It is dealt with the formalization of such cognitive architectures based on recursive deterministic abstract automata. The work introduces a method of automatic contexts formation in systems of ambient security...
This paper deals with a numerical solution enabling universities to extend the functionality of their distance learning platform to improve not only their model of delivery of educational content but also their evaluation of learners' knowledge. Indeed, this paper proposes a solution for e-learning platform Moodle, to create virtual classrooms, integrating video, audio, chat, audio recording of different...
College students often collaborate in some projects or contests with other students from different majors, but current team seeking system has some limitations on finding teammates. In this paper, we design a multi-tenant college sustained team seeking system, aiming at establishing a sustained team among college students who have similar interest. We present the architecture, core modules, and some...
This paper presents a collaborative software development platform allowing traditional and virtual universities actors who are geographically distant to work on a software development project using common (usual) programming languages. In the context of the virtual universities operating in the field of STEM (Science, Technology, Engineering and Mathematics), pratical classes are needed to acquire...
During the last years, because of the evolution of Cloud applications and the attractive advantages given to consumers, many companies outsource their data and Information Technology (IT) system to the Cloud based technology. With the growth in the number of Cloud Service Providers, many enterprises and organizations can use and associate services from multiple providers. There may be many Internet...
Today, Smartphones are very powerful, and many of its applications use wireless multimedia communications. Prevention from the external dangers (threats) has grown up to be a big concern for the experts these days. Android security has become a very important issue because of the unrestricted application it provides and the feature that make it very easy for anyone to develop and published it on Play...
In this paper, we propose an optimal assessment of internal control impact on banking risks by making automatic the residual risk estimation step of FMECA which is based on an inductive reasoning to study causes, effects of failures and their criticality. For this we defined three equations based on maturity and type of controls then we have obtain a mathematical model which is applied on 333 risks...
This paper proposes a collaborative system based on WebRTC technology to improve digital universities e-Learning environment. It allows teachers and students, through a web browser, to communicate via chat, audio and camera. It also supports file transfer and screen sharing for computer connected lab equipment. All these features are functional in an IP environment without need for Internet access...
Vehicular Ad Hoc Network (VANET) is an instance of MANETs that establishes wireless connections between vehicles. Recently, it was shown for the case of highway traffic that position-based routing protocols can very well deal with the high mobility of network vehicles. In VANETs, these routing protocols must be adapted to vehicular-specific capabilities and requirements. As many previous works have...
The complex data transfer applications, such as the telephony, video on demand and multimedia conferencing, have become a fundamental requirement. The aim of these applications is to accelerate the information transfer as audio and image packets flows format, comparing to other data formats. The architecture of services' differentiation was suggested as a simple solution to provide different quality...
Global Governance of projects requires cooperation between several actors. In general, such cooperation is ensured by building network collaboration between entities who want to collaborate. In spite of the existence of a number of works interested in collaboration network, only few of them were focused on how to construct a network. In this paper, we address this topic through Actor Network Theory...
In order to measure the urban traffic congestion, a multiagent system that consists of several locally operating agents each achieving a specific task is proposed. The traffic light patterns are calculated by considering different constraints so as to minimize an evaluation criterion. The proposed system aims at managing the gradual congestion of the traffic. As one section of the intersection becomes...
This study aims at calculating, the road urban traffic congestion using a suggested adapted CRONOS model. For the model simulation we propose adapted algorithm. We compare our adaptive system results to others given by urban traffic systems based on fixed pattern lights. The system is designed to make equilibrium between the length queue and the states of lights to search optimal strategy guarantying...
Data publishing has become an import way for information sharing. However, data privacy is still a challenge issue. When publishing data frequently, certain sensitive accurate trend may leak. Some significant sensitive overall information may be got from these published time-dependent data sets. It may result in serious consequences and heavy loss. For this issue, this paper proposes a group privacy...
