Earth is known as the "Blue Planet". 70% of the earth's surface is covered with water. It has an abundance of water, but unfortunately, only a small proportion is available to humans. This resource, which becomes increasingly limited, is essential to life and an important component for the development of agriculture, energy production, industrial activities and domestic consumption. The needs are thus in a very fast growth. Against this reality, it falls to us to preserve this resource and to make the best possible use of it. In this context, solutions started to appear allowing more efficient management of water resources. This paper provides the implementation of a software solution that aims to reduce the domestic water consumption according the basic daily activities and needs. This management is in fact a control of the consumption by predicting the tasks which are allowed to satisfy by specifying the volumetric flow used. The system will help the users with decision making according to their needs and will enable them to satisfy a large number of daily tasks without excessive water use. © 2016 IEEE.

This communication presents the design of down tilted 3D Taper Slot Antennas suitable for base stations of future generation mobile communication. We designed a novel Vivaldi antenna with wide frequency band performance covering a larger band than the 4th Generation with a vertical tilting to suit the bases station coverage requirements. A downscaled version of this metal only antenna is advantageous for higher frequency bands of the 5th Generation. The available space inside of the 3D structure is suitable to integrate low noise amplifier as near as possible to the feeding point minimizing the losses in the cable while maintaining good performance in terms of gain and efficiency. Circular antenna array of (4G) and (5G) antenna elements are simulated in terms of reflection coefficient and inter-element coupling. We developed and measured a prototype of a single (4G) antenna. Good agreement is obtained between simulation and measurements. © 2016 IEEE.

Mobile cloud computing is a rapidly increasing technology where user's demand, for cloud contents, might exceed the capability of mobile networks even with 5G. Multicast communication can offer excellent service for multiple applications, but in some scenarios its efficiency can drop to reach that of unicast. In this work, we will propose a mechanism to optimize the allocation of radio resources when used for multicast, thus offering the mobile operator an opportunity to increase profit without affecting user satisfaction. © 2016 IEEE.

The wide deployment of public cloud computing infrastructures has become an appealing solution for the advantages of flexibility and cost saving, but the risk of being exposed to privacy and security issues refrains a lot of customers from risking their sensitive data to the cloud. The data owners do not want to move to the cloud unless the data confidentiality and the privacy of their queries are guaranteed. How can we structure information sharing in the cloud between different parties and fully realize the benefits of cloud computing, and at the same time sensitive attributes/values are kept confidential except for the parties to whom they belong? In this context, we contribute a privacy preserving scheme for face recognition and classification in which a party willing to classify a face instance against a protected face database at the cloud would have this capability without revealing the instance to the cloud or revealing the database to the party. © 2016 IEEE.

Content Based Image Retrieval is the appliance of various pixel-level computation techniques, which assists the connection between image querying and human perception. Low level features are extracted by CBIR systems like color, texture shape and position. Next to audio features, a gap is formed between these content based low-level ones and the high-level semantic concepts. Multimedia Join comes to build the connecting bridge over these breaches, one more improvement on the human-machine interface. Video is an important brick in Multimedia Join since it’s a complex type of data. Images on the other hand are the building blocks of videos. In this paper we introduce, develop and test a framework of video join, by applying content based image retrieval methods. A multimedia join model was conceived and partially implemented on the video level. A new approach is proposed and implemented in order to optimize the joining time. The testing phase major lines consisted on video-to-video association and on scene-to-scene association. © 2017 Taylor & Francis Group, London.

The tremendous sharing of multimedia objects on the web shed the light on several privacy concerns related in essence to the safe publishing of end users' personal data. Providing techniques to protect multimedia objects faces several difficulties due to multimedia objects' heterogeneous and complex structure on one hand, and on the other hand, the wide range of information that could be used to describe their content. In this paper, we present a flexible security rule specification toolkit for multimedia objects. Our toolkit is based on a security model and a core ontology in which we populate the model's related information and multimedia objects data. To specify security rules, we use the SWRL language in order to address both, the content and the context of multimedia objects.

The Stroop Color-Word Test-Victoria version (VST) is a measure of executive function commonly used in neuropsychological evaluation. Because of its short administration time, the VST seems particularly appropriate for use in geriatric populations and with those suffering from dementia and who are prone to fatigue during neuropsychological examination. In this study, we examine the influence of demographic characteristics on VST score and present descriptive data for a sample of 244 elderly French speakers (50-94 years of age). Normative data corrected for age and education are provided for clinical use. Furthermore, by comparing the VST performance of patients with the Alzheimer-type dementia to that of 40 matched healthy controls, we provide clinical evidence suggesting that the VST has a clinical utility in the assessment of inhibition in AD. © The Author 2011.

Software keyboards were designed to provide accessibility to mobile users as well as to people with motor disability. Text entry is henceforth made possible on portable devices such as mobile phones, tablets, pads. Despite their obvious utility, these keyboards present major drawbacks in terms of speed of acquisition and induced fatigue comparatively to conventional physical keyboards. Optimization efforts have showed efficacy by adding prediction lists and dictionaries. Other researches have considered the effect of the position of characters and the prediction list relatively to the time of acquisition and performance. Those researches were designed for computer software keyboards. In this paper, the position of the prediction list is investigated on a mobile device. The “MobiCentraList” is the mobile version of a previous computer software keyboard “Centralist” which was developed for this purpose. The position effect of the prediction list is studied and compared to natural software keyboards. © Springer International Publishing Switzerland 2016.

Magnetic materials are fundamental part of non-reciprocal microwave components such as isolators and circulators. In order to improve the effect of the isolation, new materials with magnetic anisotropy were studied such as composites, but the determination of their magnetic properties is still a non-trivial mission. While the miniaturization of these microwave components is becoming more compulsory, a new characterization method suitable for thin magnetic layers is presented. The described technique allows the estimation of diagonal and extra-diagonal components of the permeability tensor. © 2015 IEEE.

Visual impairment or vision loss is the main reason for reduced mobility in humans. Visually Impaired (VI) people require continuous assistance during their movement. Researchers and scientists have put many solutions to assist those people in the activities of their daily living (ADL). The current research delivers a novel indoor navigation system for visually impaired people. The proposed solution is designed for indoor use only (house, office, companies, etc.). It provides the visually impaired person the ability to navigate without any other hardware assistance. The proposed system architecture uses a network of IP cameras installed at the ceiling of each room. A remote processing system analyzes-by computer vision algorithms-photos taken from the environment in order to inform the subject about his location and reacts accordingly to deliver the adequate assistance. A guidance algorithm helps him reach his destination using a simple interactive mobile application installed on his smart phone. The proof of concept prototype was designed with one camera on top of a wooden floor model to simulate the system. Results showed good reliability in indoor navigation and obstacles avoidance. © 2015 IEEE.
