This research work presents a new three-level space vector modulation (SVM) based on artificial neural networks (ANNs) of a doubly fed induction generator (DFIG) integrated into a wind energy conversion system (WECS) is presented. The traditional direct vector control (DVC) using PI controller presents considerable stator reactive and active ripples. In order to ensure a robust DVC technique for the DFIG-rotor side converter and reduces electromagnetic torque, current, reactive and active ripples, a DVC based on NSVM inverter is used in this work. Simulation results show the efficiency of the proposed technique of control especially on the quality of the provided power comparatively to a DVC with pulse width modulation inverter.

This paper presents a digital implementation of 4-D autonomous hyperchaotic system on a Field Programmable Gate Array (FPGA) technology. In the design, the system parameters are selected according to the requirements for obtaining a hyperchaotic behavior. The hyperchaotic nature is theoretically verified by using bifurcation analysis and Lyapunov exponents’ calculus; and experimentally assessed by the FPGA implementation. A master-slave scheme for secure data transmission is used. Active control is applied to carry out the synchronization between the master and the slave. FPGA technology is applied in order to be implemented in digital form the 4-D continuous system using a XILINX VERTEX5 chip. The digital sequence generated from the FPGA device is observed in our experimental setup. The implementation with 32 bits fixed point is chosen; highlighting the role of synchronization mechanisms of chaotic systems in the success of these transmissions.

The ElectroMagnetic Compatibility (EMC) requirements in accordance with CISPR 22 standard recommend that differential mode (DM) disturbances generated by equipments have to be less than the normative template. The boost converter -equipment under test- treated in this work is modeled by a theoretical formula, on the DM referential. The built model let as to compute the DM impedance, across a long frequency band taking account essential parasitical imperfections. A comparison study will be done, thanks to Pspice simulations, analytical studies and experimental measurements using an impedance measurement bridge. The link between the differential mode impedance with some parameters such as the boost inductor and the duty cycle $alpha$ will be highlighted.

Developing a competent and accurate Computer-Aided Diagnosis (CAD) system to assist medical experts in making diagnosis requires a substantial amount of labeled (diagnosed) samples, however collecting labeled data is very costly and challenging when it comes to expert’s annotation. This task is considered as a burden, and is both very time consuming and expensive. The framework of Semi-Supervised Learning (SSL) approach addresses this problem by taking advantage of the abundant amount of accessible unlabeled(undiagnosed) data together with the few limited labeled data in order to train precise classifiers while requiring less human effort and time. This paper reviews different CAD systems using SSL for numerous tasks; the methods used and results obtained are discussed and key findings are highlighted; to conclude with a presented proposed approach for the development of a CAD system; applying Semi-Supervised learning for the classification of cases in order to improve the performance of Case-Based Reasoning(CBR) system.

In order to ensure the high availability of web services operations; recently we have opted for a communities-based approach. This approach consists in grouping in a single cluster all operations offering the same functionality (the same outputs). The client (for a substitution requirement e.g.) can select, in this set, the operation (s) according to their non-functional criteria but also according to their inputs parameters. The customer is satisfied, on the one hand, he has all similar operations as the failed one, but, on the other hand, he feels lost: what are the operations taking this or that inputs, as the failed one? In this context, and in order to guide and help users in their choices, we have considered the reorganization of the clusters by specifying the relations linking the inputs of the operations of the same cluster.

A mobile peer-to-peer (MP2P) system results from overlaying a peer-to-peer (P2P) network over a mobile ad hoc network (MANET). This system suffers from frequent and irregular connection/disconnection of peers which can cause the unavailability of files in the network and this problem impacts the files search performances. Thus, it is important to address the files availability issue. In this paper, we propose CRS, a clustering-based replication strategy to improve file availability which enhances the search efficiency. Our proposal is based on global file availability and popularity estimations to choose the suitable file to replicate and the suitable replica degree. Simulation results show that CRS has good search success rate and low overhead regarding to other replication strategy.

A methodology to study the compressive strength of hard cement mortar with recycled cellulosic fibers under different conditions based on the full factorial experimental design and artificial neural network is presented in this research work. An experimental procedure to show the parameters that affect the compressive strength as percentage of fibers, age, and compaction pressure is conducted. The effect of these parameters and their interaction effects for compressive strength response are determined using full factorial design. Statistical analysis shows that the percentage of fibers has a major effect on the compressive strength. The use of the artificial neural network approach in the prediction of compressive strength indicates a considerable correlation between the model obtained from this approach and the experimental results.

This paper presents a new interferometric coherence optimisation approach, based on complex Flower Pollination Algorithm (FPA). FPA is a new recently developed algorithm based on pollination process of plants, that is used to solve constrained and/or multi-objective optimization problems. The proposed approach gives an additional option by enabling the optimization of a specific scattering, for example surface scattering, passing by double bounce scattering, or dipole scattering $cdots$ etc. by defining the scattering vector format. Moreover, a modified version of FPA is proposed, which make it faster, and give better outcome in term of interferometric coherence mean. A comparison of the proposed algorithm with previous optimization methods will be made showing its efficiency and its good outcome in term of phase quality, and residues percentage. The obtained results are interesting and promising.

In order to solve the influence of electromagnetic interference on the electronic devices which may have tremendous effects on its proper functions if the shielding protection is not appropriately implemented. The metals are increasingly used in the most shielding applications, but the main problem is this metals have a good shielding efficiency and works at high temperature. In the present paper, we study the effect of temperature in the frequency range 0 Hz-108 Hz on the physical proprieties of metals especially on the conductivity taking the example of copper sheets.

This paper deals with the development of a novel Ultra Wide Band (UWB) microstrip antenna, using the Ansys HFSS 18.0.0 simulation tool and Anritsu MS4644A Vector Network Analyzer (VNA). The developed antenna consists of a patch of non-regular shape etched on an FR4 dielectric substrate, excited with a 50 Ohm microstripline, having a defected ground plane. In order to improve the bandwidth, the design of the antenna is based on staircase patch shapes, curved shapes, together with the presence of a slot and a notch of a defected ground plane. The obtained bandwidth of the antenna is 2.42–11.87 Ghz. Data concerning the radiation pattern of the antenna are shown in conjunction with a parametric study of the effect of antenna dimensions on its characteristics. The obtained results in the experimental validation step using the VNA, are quite conclusive, showing the performance of the antenna realized in terms of bandwidth and matching and also fulfilling the conditions required by the US FCC standard 3.1–10.6 Ghz bandwidth, which incorporates all the UWB standards of the world.
