A new algorithm for face recognition is proposed in this work, this algorithm is mainly based on LBP texture analysis in one dimensional space 1DLBP and Principal Component Analysis PCA as a technique for dimensionalities reduction. The extraction of the face's features is inspired from the principal that the human visual system combines between local and global features to differentiate between people. Starting from this assumption, the facial image is decomposed into several blocks with different resolution, and each decomposed block is projected in one dimensional space. Next, the proposed descriptor 1DLBP is applied for each projected block. Then, the resulting vectors will be concatenated in one global vector. Finley, Principal Component Analysis is used to reduce the dimensionalities of the global vectors and to keep only the pertinent information for each person. The experimental results applied on AR database have showed that the proposed descriptor 1DLBP combined with PCA have given a very significant improvement at the recognition rate and the false alarm rate compared with other methods of face recognition, and a good effectiveness against to deferent external factors as: illumination, rotations and noise.

In the wake of flexible querying system, proposed in [26], [28], [29], in which the bipolarity of the form “and if possible” is used as means to express user preferences over relational databases and ontologies (fuzzy bipolar DLR-Lite), we introduce in this paper the user query evaluation process, under the extension of our flexible querying framework to bipolar conditions of the form “or else” [20], [19]. Queries addressed to our system are bipolar conjunctive queries made of a conjunction of atoms corresponding to concepts of an ontology. The proposed evaluation process is carried out in two main steps. The former consists of query derivation to compute complementary queries, based on substitutions of query's atoms involved in fuzzy bipolar subsumptions expressed in the considered bipolar ontology. The latter deals with the translation of the obtained set of queries from the first step into bipolar SQLf statements, which are finally evaluated over a bipolar relational database managed by PostgreSQLf DBMS extended to bipolar datatypes and functions. Three algorithms are then developed in order to perform applicable substitutions, to derive corresponding complementary queries and to translate them into Bipolar SQLf statements. The feasibility of the approach is shown through a prototype developed in the field of multimodal transport systems.
在[26]，[28]，[29]中提出的灵活查询系统中，使用形式“and if possible”的双极性作为表达用户对关系数据库和本体的偏好的手段(模糊双极性DLR-Lite)，本文介绍了用户查询评估过程，将我们的灵活查询框架扩展到形式“or else”的双极性条件下[20]，[19]。向我们的系统提出的查询是由与本体概念相对应的原子的连接构成的双极连接查询。拟议的评价过程分两个主要步骤进行。前者由查询派生组成，以计算互补查询，基于在考虑的双极性本体中表示的模糊双极性包含中涉及的查询原子的替换。后者处理将从第一步获得的查询集转换为双极性SQLf语句，这些语句最后在扩展为双极性数据类型和函数的PostgreSQLf DBMS管理的双极性关系数据库上进行评估。然后开发了三种算法，以执行适用的替换，派生相应的补充查询并将其转换为Bipolar SQLf语句。通过在多式联运系统领域开发的原型，证明了该方法的可行性。

Wireless Sensor Networks (WSN) have registered a large success in the scientific and industrial communities for their broad application domains. Furthermore, the WSN specification is a complex task considering to their distributed and embedded nature and the strong interactions between their hardware and software parts. Moreover, most of approaches use semi-formal methods to design systems and generally simulation to validate their properties in order to produce models without errors and conform to the system specifications. In this context, we propose a Model Driven Architecture (MDA) approach to improve the verification of the WSN properties. This approach combines the advantages of the System Modeling Language (SysML) and the Modelica language which promote the reusability and improve the development process. In this work, we specify a model transformation from SysML static, dynamic and requirement diagrams to their corresponding elements in Modelica. Thanks to the SysML requirement diagram which is transformed into Modelica properties (constraints), we propose a technique using dynamic tests to verify WSN properties. We have used the Topcased platform to implement our approach 1 and chosen a crossroads monitoring system which is based on wireless sensors to illustrate it. Besides, we have verified and validated some wireless sensors properties of the studied system.

In this paper we propose a multi-agent approach based on the combination of a meta-heuristic approach with mathematical operators for image segmentation. Our model used resolution, edge and region agents. The role of resolution agent is to describe the contents of the image using multiple representations with decreasing resolution while the edge agent detects edges in one level of resolution images. Region agent makes use of spider's webs to detect different regions. The proposed approach has been implemented in the JADE agent platform over synthetic and a satellite image. An unsupervised measure was used to improve the effectiveness of our model.

The SEVIRI (Spinning Enhanced Visible and Infrared Imager) sensor on the MSG-2 satellite provides an image every 15 minutes, so the development of a system that can exploit the temporal behavior of the observations of terrestrial half-disc, is crucial for these near-real-time applications. To validate the processing results, we need to use some others sensors, like AVHRR (Advanced Very High Resolution Radiometer) for NOAA-19 satellite. A terrestrial station is required to collect and follow the temporal, spectral, and space evolution of the treated topic of interest. In this research, we realized a ground station, to receive daily data from either HRIT (High Rate Image Transmission from METEOSAT-9 geostationary satellite baptized MSG-2), HRPT and APT (High Resolution Picture Transmission and Automatic Picture Transmission from NOAA-19 polar satellite) real time satellite data transmissions. A motorized dish antenna is used to receive HRPT images. In the APT system, a fixed omnidirectional antenna is used. Some results of acquisition and treatment (by our MSGViewer and PCNOAA developed softwares) are described in this paper. After calibrating each data, we have developed various thematic products, such as, terrestrial Albedo, brightness temperature and others treatments. The data gathered is useful in many remote sensing applications. In this work, we are arrived to receive in real time the APT and the HRPT format of the NOAA-19 satellite and HRIT format from MSG-2 satellite. Different combinations between visible and infrared bands based on images that the NOAA satellite and MSG-2 has obtained through its AVHRR Radiometer and SEVIRI Imager.

Data aggregation in wireless sensor networks (WSNs) provides a great reduction of energy consumption. The limited resources of sensor nodes make the choice of an encryption algorithm very important for providing security for data aggregation. Asymmetric cryptography involves large ciphertexts and heavy computations but solves, on the other hand, the problem of key distribution of symmetric one. The latter provides smaller ciphertexts and speed computations. Also, the recent researches have shown that achieving the end-to-end confidentiality and the end-to-end integrity at the same is a challenging task. In this paper, we propose (SA-SPKC), a novel security protocol which addresses both security services for WSNs, and where only the base station can verify the individual data and identify the malicious node. Our scheme is based on stateful public key encryption (StPKE). The latter combines the best features of both kinds of encryption along with state in order to reduce the computation overhead. Our analysis shows the security and the efficiency of our scheme for WSNs.

Enterprise Service Bus (ESB) is an SOA-based software architecture for business application integration in distributed and heterogeneous environments. The proposed solutions so commercial as open source offer the same set of basic services such as message transformation, message routing, security. However, none of them take advantage of the multicore/multiprocessor technologies which make plausible the massively parallel processing. In this paper, we describe a new ESB architecture denoted Massively Parallel Application Bus (MPAB) which meets this challenge.
