This paper presents an innovative web-based Decision Support System (DSS) for the fuel distribution to facilitate and to optimize de the daily delivery schedule. It integrates a new mathematical model into a supply chain management information system and a geographic information system. The studied problem refers to a complex delivery process of oil products from a distribution center to all the service stations, where products must be delivered under the time windows, using a set of vehicle with multiple compartments. This problem is modeled as a Multi-Compartment Vehicle Routing Problem with Time Windows (MC-VRP-TW). We present a Mixed Integer Linear Program (MILP) and we use the optimization software CPLEX to solve it. In order to assess the performance of the proposed DSS, we conducted computational experiments on two real-world data of a Tunisian fuel company. Numerical results show the effectiveness of our decision support system.

Educational computer games have been adopted, for a long time, as a valuable tool in the learning and teaching of several subjects such as physics concepts, science, reading and spelling. These games are considered as a powerful instrument for teaching as they and succeeded in improving learners' motivation, increase learners' desire to learn, make learning more enjoyable, and lead learners to complete more difficult work. However, the use of these games for learning also has potential to affect the learning experience negatively if the game designer does not balance between a set of critical factors. Generally, the right combination of fun gameplay and appropriate learning experience constitutes a good opportunity for creating an effective educational game that supports the learners to acquire knowledge and to increase their competency. In this context, this paper introduces and describes a new educational computer game, called “LAST MISSION”, especially designed for learning the history of the World War 1 and the World War 2. In addition, this work seeks, through a pilot study, to investigate whether the use of this educational computer game has a positive effect on learners' level of knowledge and learners' satisfaction.

Recognizing the relation of entailment between sentences is an important and common part of linguistic communication. The recognizing textual entailment task has been proposed as a solution for this problem. In this paper, we present an Arabic Recognizing Textual Entailment Tool called Ar-SLoTE «Arabic Semantic Logical Textual Entailment Tool». The proposed tool is composed of five modules: pretreatment, linguistic analysis, first-order logic representation, features extraction and entailment decision modules. It extracts the logical representations of the hypothesis/text pairs in order to extract valuable and informative features namely, predicates-arguments overlap, semantic similarity and named entity matching. Ar-SLoTE is destined especially to Arabic factual question/answering systems and the attained result is very encouraging.

Over the last decade, computer-based educational games have become more and more prevalent. With the increasing applications of these games in education, an increasing number of studies investigate the use of these games for collecting useful information about learners while playing games. In fact, computer-based educational games are not just considered as interactive didactic support that is capable to raise the learners' motivation and engagement, but also as the means to give them opportunities for interaction with the computer, which can be exploited for creating a reliable learner model. This paper introduces a computer-based educational game and proposes several scenarios for extracting a specific learner characteristic while playing this game, which is the learner's values.

In this work, we propose a new approach for recognizing sign language hand shapes using electromyogram (EMG) signals. The processed signal is obtained from the Myo armband witch uses eight sensors. The new approach is based on MFCC and DTW methods and the K-NN classifier. We also present the experiments carried out for the validation of the proposed approach as well as the obtained results.

A thorough look at a unique platform that provides a comprehensive set of services and resources to emerging technologies and innovations in the Arabic speaking world. These services design the sole purpose of improving the lives of people with functional limitations. Based in Qatar, the Mada Innovation Ecosystem sets out to provide access to financing, community resources, policy and best practices, delivery channels, collaborations, data and research, and technical expertise. The goal of the platform is to increase the availability of Arabic language solutions, or tools developed in the Arabic world, hence improving the digital accessibility to people with physical, hearing, visual and learning disabilities.

Information technology (IT) embodies great promise in improving independence and overall quality of life of older Canadians with cognitive disabilities (CD). Nevertheless, these users often struggle to access and use IT. Thus, they may be prevented from fully participating in daily activities and are at risk of social isolation. Caregivers play an important support role in interventions for older adults, including assisting with access and use of IT. However, less is known about this topic with regards to persons with CD. This short paper aims to explore the perspectives of older adults with CD and their caregivers on their access and use of IT, and the role that caregivers' support and attitudes play in this matter. We used a qualitative descriptive approach that draws on data from 15 semi-structured interviews conducted with six older adults with CD and nine caregivers. Our findings revealed three interrelated themes: (1) limited IT access and use by older adults with CD, (2) older adults with CD's clear and unmet needs in accessible design and support for access and use, and (3) the central role of caregivers in providing this support. We conclude that all concerned stakeholders designing or delivering technology-based solutions targeting older adults with CD must account for the importance of caregivers' role in older adults with CD's access and use of technology. They need to engage and consider the needs of both groups, while not undermining older adults' autonomy.

Since their emergence just over a decade, the Open Educational Resources (OER) have been essential in the development of educational strategies and policies in many countries. The first part of this article describes briefly the state of the art in terms of definitions and applications of OER. Then we will focus on the adoption of OER at Cadi Ayyad University. In particular, we will present and discuss some initiatives developed at Cadi Ayyad University. Finally, we will present challenges facing OER in our university within different factors.

Open education could be the key to solving several problems in rural education, including costly learning materials, accessibility, gender disparity, poor learning outcomes, lack of qualified teachers and high drop-out rate, which have been frequently reported by international organizations, such as United Nations Educational, Scientific and Cultural Organization (UNESCO) and Arab League Educational, Cultural and Scientific Organization (ALECSO). Therefore, this paper offers a holistic understanding of how Open Educational Resources (OERs) characteristics could solve these learning challenges in rural areas to provide similar learning experiences as students in urban areas. The findings of this paper can enhance rural education by detailing several ways of using OER to enhance major rural education challenges. This could help establish social justice betwee rural and urban areas students.
