Video streaming services over the Internet is being widely used in mobile networks. From providers' point of view, the success of such service is highly correlated with the end-user degree of satisfaction which is measured in terms of Quality of Experience QoE. In fact, most of video streaming providers are adopting adaptive streaming solution that offers a better experience to the end user since it is better to have a lower video quality instead of no video at all. Currently, service providers start to secure data transfers using encrypted stream, most importantly HTTPS, as it is one pillar of the whole experience of video stream services. In this paper, we are addressing the efficiency of video encryption schemes when facing mobile cloud system requirement without compromising the end user global experience of video services.

Automatic detection of human in a video sequence is a canonical instance of object detection. It's considered as a nonrigid object; it has many appearances at different perspectives. Different approaches are used by several methods to combine what is specific to the pedestrian detection, and what is common to the object recognition. A robust solution to this problem would have numerous applications to design smart systems, including video surveillance, power management, vehicle driver assistance systems, and evaluation of advertising policies. In this article we will discuss the main techniques of human (pedestian) detection on video sequence. Especially those how are learning-based methods. Then we describe in general terms the type of information that can be extracted once the detection is performed.

In this paper, we present a new inspired metamaterial rectenna which is designed in the microstrip line structure at 5.8 GHz for the wireless transmission of microwave power. The proposed rectenna achieves RF-to-DC conversion efficiency of 52% and a DC voltage of 0.8 V when the received RF power is 1 mW at 5.8 GHz. The feasibility of this concept is presented through full-wave simulations. These simulations results will be updated at the conference with measurement results.

In this paper, a new meander line UHF RFID tag antenna loaded with split ring resonator is presented. The antenna has a simple structure and low profile with only one layer of FR4 dielectric substrate and metallization. To achieve a good and impedance matching, the antenna has been loaded with a metamaterial structure (SRR). The obtained impedance bandwidth covers the American band (900–928 MHz). The proposed design provided quasi omnidirectional radiation pattern and radiation efficiency near to 90% in the operating band. The calculated reading range was 4.36 m at center frequency band.

The fundamental objective of an information search system based on interest center and the user profile is to return, from a collection of documents, the elements that are relevant to specific user needs. The selection of only documents interesting a user is done on the basis of interest center, calculated from the information about the user named user profile. The information retrieval systems converge towards a semantic representation of the user profiles. In contrast, it does not take into account the semantic links in defining the center of interest. So, we used a graphical representation of the user profile based on a domain ontology. So we have been able to use the mathematical power graphs to infer the user's center of interest.

Steganography is the art of dissimulating information into a digital signal like audio, image, or video. It is the technique of hiding secret data into a carrier to convey messages. Digital images are one of the media that is suitable to convey messages due to several reasons. Firstly, digital images are often transmitted over the Internet which would arouse little suspicion. Secondly, the high correlation between pixels provides rich space for data embedding.

NoSQL databases are designed to solve data processing problems in volume. Growth data today pushes us to think about new concepts and approaches for converting data from a source database to a NoSQL database. This paper describes some approaches, methods of migration, database reverse engineering, and offers a migration approach from a relational database to a Document-oriented database NoSQL (MongoDB). The approach based on the achievement of a data model, from which we proceed to the migration of schema and data mapping, while ensuring the integrity constraints between collections.

Cloud coverage obscures the sunlight, it can be identified as the major factor that significantly decreases the total irradiance received by photovoltaic panels, and then the power generation is intermittent. In this paper, and in order to predict the energy production by a solar installation, we analyze the acquired ground based images of the sky to extract its actual status (clear, partially cloudy, or totally cloudy). An embedded system is dedicated to simultaneously capture images and estimate the power generation. The accurate sky status is determined by comparing the brightness of the sun zone in the digital image to its surrounding area. The experimental results are promising and shows that the developed techniques can be easily embedded in solar plants to accurately predict the short time energy production.

the idea of Service-Oriented Computing (SOC) is to understand users' requirements for Service-Based Applications (SBAs). We propose an adaptation-centric approach which allows: (i) modeling users' requirements for Service-Oriented System with the MAP formalism using an Intentional Service Model (ISM); (ii) ontology and the aspect according to the contextual changes in order to inject it in the process BPEL; and (iii) provides architecture for a support tool. We validate our approach by performing experiments on an e-tourism application. The result is an adaptation framework that can guide software engineers in developing adaptable service-based applications.
