The development of satellites with the strong temporal repetitiveness and development of remote sensing techniques resulted in the advancement of change detection techniques from geospatial imagery. The natural events cause many modifications in the control process of the ecosystems. There is a necessity of using a method capable to map, categorize and monitor areas affected by natural events along time. In this article, a novel methodology of change detection is proposed in order to improve the change detection from multi-date satellite image using the source separation. The results obtained by our methodology are efficient and effective.

Renewable energy production is not continuous and reliant on climatic conditions as well as geographical location. Deal with the problem of intermittency of renewable energy sources have emerged as the biggest interests of the last decade. To overcome the issues inserting batteries to these renewable energy sources is seen as an attractive option. Such energy systems may simultaneously tackle the concerns regarding climate change, energy security, optimal design, and problems related to the battery bank. The present paper proposes the development of a Raspberry Pi-based hardware platform for data acquisition, supervision and energy management of a hybrid PV/WT/Batteries system. It may be speculated that integrating smart technologies in the renewable energy sector into a single hybrid energy system, coupled through informatics linkages, would enable to overcome the drawbacks inherent in the intermittent nature of these energy sources.

The aperture coupled microstrip antenna (ACMA) presents a good candidate for automotive radar application due to its compacity, light weight, low cost and the simplicity of its integration in antenna array. Typically, it consists of two substrates divided by a conductive ground plane in between. The patch is located on top of the upper substrate and the feedline is situated on the bottom substrate. Thereby, this antenna avoids parasitic line radiation which can, in some cases, disrupt side-lobe levels. This communication presents the design of a Multilayered Aperture Coupled Microstrip Antenna (MACMA) for 79 GHz automotive radar applications. This antenna presents in addition a Rohacell HF 51 foam sandwiched between the ground plane and the patch substrate layer. The multilayer substrate is used to minimize the coupling between patch antennas, in particular, surface waves which are not significantly excited on foam dielectric material thanks to the low synthetized permittivity. MACMPA model was done with High Frequency Structure Simulator (HFSS) software tool that could treat 3D full-wave electromagnetic structure analysis based on Finite Element Method.
孔径耦合微带天线(ACMA)具有体积小、重量轻、成本低、集成简单等优点，是汽车雷达应用的理想选择。通常，它由两个基片组成，中间有一个导电地平面。所述贴片位于所述上基板的顶部，所述馈线位于所述下基板上。因此，这种天线避免了在某些情况下可能破坏副瓣电平的寄生线辐射。本通信介绍了用于79 GHz汽车雷达应用的多层孔径耦合微带天线(MACMA)的设计。该天线在接地面和贴片基板层之间夹有一层Rohacell HF 51泡沫。多层衬底用于最小化贴片天线之间的耦合，特别是由于泡沫介质材料的低综合介电常数，表面波在泡沫介质材料上不被显著激发。采用基于有限元法的三维全波电磁结构分析软件HFSS (High Frequency Structure Simulator)建立了MACMPA模型。

This paper investigates the performance of Narrowband power line communication (NB-PLC) and radio frequency (RF) technologies under rural environment for smart metering application. It addresses the environment influence on these two links using different modulation sizes (BPSK, QPSK, and 16 QAM) for a Smart Grid implementation. Computational simulations based on physical layers of IEEE 1901.2 and IEEE 802.15.4g standards selected for PLC and Wireless channel models show that in rural environment categorized as low density area with very low number of loads and almost no obstacles, RF with BPSK modulation shows higher performance for given SNR value, it performs a gain of 7dB that can be reached compared to PLC link.

In this communication, a computational and experimental investigation at terahertz frequencies of Planar Gaubau Line combined with Split Ring Resonator is reported. Different parameters such as gap width, position and gap orientation that tuned the resonance peak are studied. The obtained results are useful for the understanding of coupling mechanism between a radially polarized wave along a metallic strip and a Split Ring Resonator.

Ensemble clustering refers to combine many clustering methods to produce better results. In this context, we propose a new clustering ensemble method inspired from cluster forests (CF) based Self-Adaptive Fuzzy C-Means (SAFCM) method. Firstly, unsupervised feature selection methodology based on the building of best variables on simulated datasets. Next, we ameliorate the CF algorithm with the integration of SAFCM to find also the best number of K groups. Finally, the modified version normalized cuts spectral clustering (Ncut) is applied to general grouping. The proposed algorithm was tested on datasets from UCI Machine Learning Repository. The experimental results indicate that our proposed method outperforms both different clustering algorithms in terms of clustering quality.

in this paper a new method for the analysis of non uniform substrate integrated waveguide transmission lines is developed. The proposed approach uses the method of moments with frequency dependent basis functions derived from the structure's propagation characteristics. The stability and speed of this method are demonstrated by analyzing non uniform structures. The obtained results for a structure with periodically varying width were compared to those obtained by HFSS simulations and a good agreement has been observed with much lower computation time.

A slotted tag antenna is presented for blood bag monitoring with good reading distance. In addition to the main radiating patch, cuts made into the ground to increase the antenna radiation efficiency and help to self-match the antenna impedance with the RFID microchip NXP G2XM IC chip in TSSOP8 (SOT505-1). The antenna structure is uniplanar and optimized to be mounted on a high-permittivity (Blood Bags) and to work in the UHF European band (865–868) MHz. Furthermore, an equivalent circuit model is presented and the characteristic of the proposed RFID tag antenna predicted by this circuit model are in good agreement with the full wave simulations. The obtained simulated show a read range of 1.28 meters when mounted directly on the Blood Bag.

In this work, a novel frequency-reconfigurable printed antenna is proposed. The structure consists of a capacitively loaded loop (CLL) introduced into the near field region of a printed monopole antenna to create multifrequency behavior. The frequency agility was realized by integrating a lumped capacitor between the CLL and the ground plane. A tuning range of 0.654-0.886GHz is successfully achieved when varying capacitance values from 0.5 to 4pF covering LTE and GSM bands while keeping the operating frequency F1=2.65GHz of the reference antenna changeless. The simulated results of return loss, surface current distribution and radiation patterns are presented and discussed.
