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.

Increasing the life time expectancy is one of the major chalenges in Wireless Sensor Networks (WSN)s. Energy consumption in WSNs is mainly due to the sensing and the transmission capabilities of the sensor nodes. In this paper, we propose an energy-saving multi-hop clustering which balances the position of powerful nodes in the sensor network and hence reduces the total energy dissipation of the nodes. Knowing the base station position and having a variable number of sensor nodes that are deployed randomly, the nodes are clustered using distinct synchronized regions, where a Cluster Heads (CH) is being specified in each region. Instead of using a circle to each cluster, we found out that it is more effective to use a rectangle which cover all the area and take all the spaces of the area into consideration, allowing all the nodes to participate in the transmission. We introduce the location based routing protocol to indicate the location of each node which is available by communicating with a satellite using GPS when nodes are equipped with a small low power GPS receiver. Simulation result of our proposed approach shows that the new algorithm can reduce energy consumption comparing to LEACH protocol by up to 20 percent and obviously improves the network lifetime. © 2016 IEEE.

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.

Sharing and publishing images and photos have become the trend of nowadays (social networks, messengers, etc.). Providing appropriate techniques to preserve privacy and protect content of sensitive and private images is an essential need. In this paper, we present a novel security model for image content protection. In our model, we provide dynamic security rules based on first order logic to express constraints that can be applied to contextual information as well as low level features of images. We finally discuss a set of experiments and studies carried out to evaluate the proposed approach. © 2012 IEEE.

A fundamental aspect of all social networks is information sharing. It is one of the most common forms of online interaction that is tightly associated with social media preservation and information disclosure. As such, information sharing is commonly viewed as a key enabler for social media preservation tasks. In the current situation, where information sharing and inter-user communications are made instantly possible via the widespread use of ubiquitous technologies, privacy related, and particularly information disclosure issues, are the obvious, much discussed, immediate consequences of information sharing. As a result, information disclosure, especially when multimedia data come to play, is critical for appropriate social media preservation strategies that consider and respect the privacy of social network users. Social media preservation must align with privacy protection solutions and consequently must protect sensitive information that social network users would like to keep private. In this paper, we propose a new approach to implement a privacy-oriented social media preservation strategy that prevents the disclosure of sensitive information. Instead of using a preserve-all strategy, we present a framework to personalize social media preservation tasks. We then describe our proposed rule-based algorithm to evaluate information disclosure addressing mainly relationship type disclosure and using shared photos. We also provide an experimental study to investigate the efficiency and the relevance of our approach. © 2015, Springer-Verlag Berlin Heidelberg.

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.
