In this paper, we provide a topology adapted to routing in delays tolerant networks (DTN). This topology improves the performance of a DTN network. The key idea behind our proposal is that incorporates three basic concepts: ferries messages, ferries routes and clusters and capable to adapt dynamically to changes in the mobile environment. Finally, The simulation results are convincing and show the relevance of the idea which allows to improve the DTN performance compared to the already existing solutions.

A Hardware-in-the-Loop (HIL) simulator renders possible to conduct on-line tests on Battery Management Systems (BMSs) with an emulated battery pack instead of a real one. In this case, the BMS can be repeatedly evaluated under the exact same experimental scenarios, with safety and accuracy, or under a flexible and beyond the normal operation area range, with less cost and time efforts. For this purpose, a multi-cell Li-ion battery pack consisting of 32 cells in series has been implemented and validated based on experimental results, converted into C code and emulated through the HIL simulator. The BMS under test is interacting in real-time with the emulated battery pack and several of its functions such as current, voltage and State of Charge (SOC) estimation are evaluated. Also, passive balancing experiments are conducted during charging in order to assess different balancing settings of the BMS as far as their respective balancing times and deviations in SOC are concerned. Finally, the energy efficiency of the BMS is accurately measured which, depending on the requirements, can achieve more than 99% of efficiency. In general, it is demonstrated that the HIL setup can provide representative outcomes at minimum resources and time requirements.

Monitoring the power system stability is one of the major challenges facing operators today. The use of the best indices is essential as a mean of decision-making; this choice can be achieved through very specific criteria such as the sensitivity. The purpose of this paper is to discuss and evaluate some voltage stability indices sensitivity. This approach permits an accurate decision-making and a reference usage depending on the point of operation and the nature of disturbance that occurs in the electrical network. The study is applied for IEEE 14-bus and the methodology has proven its effectiveness under different scenarios of contingencies.

Every day trillions of data are generated across the world and put the information systems facing the emergence of big data phenomenon. This vertiginous evolution makes the enterprise confronting the challenge to build its own big data. To achieve the challenge, the enterprise is supposed to embark on big investments in terms of resource and material to process petabytes of diverse data, this last are sometimes useful and sometimes useless. The problem here is how to optimize data relevancy to extract value from the big data sources. From this Reasons, we propose in this paper an ETL and MapReduce Hybrid Approach based on Data Filtering and Processing to build an effective on-demand Dimensional Big Data, enabling enterprises to process relevant data in efficient and effective way according to the stakeholder's needs.

Identity of a person via voice is one of the most interesting techniques used for user identification. Almost of speaker identification systems are based on distance computation or likelihood. Accuracy of identification process depends on: (i) the number of feature vectors, (ii) their dimensionality, and (iii) the number of speakers. This paper aims to develop a system able to identify a person from a sample of his speech. Recognition relies on a text-dependent system using English words as a password. Speech features are extracted using Mel Frequency Cepstral Coefficients (MFCCs). The recognition is based on discrete to continuous algorithm. Experimental results demonstrated that the proposed system return good accuracy rate.

With the explosive growth of digital transactions, the security of personal identity presents a serious challenge in our world today. It has become necessary to provide reliable and robust recognition systems. To overcome this problem, we propose a novel approach for finger knuckle print using Compound Local Binary Pattern (CLBP). Unlike the LBP operator, the CLBP add an extra bit for each P bits encoded by LBP corresponding to a neighbor of the local neighborhood, in order to construct a robustious feature descriptor that exploits both the sign and the inclination information of the differences between the center and the neighbor gray values. The effectiveness of proposed method has been verified on PolyU FKP database. The experimental results show that the recognition rates are significantly improved compared with others methods existing in literature. The recognition rate of the proposed method is the highest among the other algorithms. The optimal recognition rates obtained is 98,18%, 99,29%, 98,48% and 98,89% for Left Index, Left Middle, Right Index and Right Middle, respectively.

The use of mobile sinks in data collection has received much attention in recent years. Mobility offers many benefits such as reliability, lifetime enhancement, security and so on. However, it poses a set of challenges the most prominent is data loss. Data collection using a mobile sink may induce huge latencies and packet drops within the network particularly when the sink moves with a lower speed and in an unpredictable manner. Thereby, some region might be visited more than others, which causes data loss due to buffer overflow. In an attempt to overcome this issue, we propose in this paper an efficient approach that balances the network storage and prevents packet drops. Nodes having run out of storage space offload their extra data to their neighbors in a proportional manner in function of their free spaces. In case all nodes have filled up their memories and there is no possibility for data partitioning, the sink is notified urgently to move towards the crowded zone to perform data offloading before the occurrence of any packet drop. Intensive simulation reveals that our approach significantly decreases packet loss and spread the load within the network.

This paper demonstrates an artificial bee colony (ABC) algorithm for MPPT for high-performance wind generators with DFIG machine under dynamic weather conditions. The wind turbine system should be operated at the maximum power point by finding out the optimum rotor speed that ensures the maximum energy is harvested from the available wind. This algorithm works without speed sensors and does not require any previous information of the wind energy system. Simulation results of the proposed algorithm have shown good performances under different wind speeds and show that this algorithm considered for MPPT is simple, accurate and most effective during variable wind speed.
