In this paper, a novel design of a biosensor based on Split-Ring Resonator (SRR) is developed for cancer cells detection in the L/C frequency bands (1–8 GHz). A comparative investigation of classic and proposed structures has been developed to demonstrate the effectiveness of the proposed structure. The simulation results show that the proposed structure achieves narrow resonance with low insertion loss, while the Q-factor increases from 1.96 to 2.47.

A Schottky diode based Cu/Ni:ZnO/InGa structure has been fabricated. The electrical characterization have highlighted the presence of negative differential resistance (NDR) effect and negative photoconductivity (NPC) in one device and at room temperature. The NDR effect can be explained in terms of trappings and detrapping of the mobile charges at the interface Cu/ Ni:ZnO. The main cause of the NPC effect is a combination between carriers injection by the external field and photocarriers due to UV illumination. As a result, these two features (NDR and NPC) lead to the optical switching effect in our device.

To illustrate the importance of renewable energy generation around the world. Renewable technology contributes to a remarkable amount of electricity to the grid. Renewable energy sources are the prime-movers of the microgrid. A microgrid is a small, parallel network of distributed generation (DG) power systems. In this paper, the hybrid energy sources resulting from nature and how to obtain the electrical energy from them, directly or indirectly, will be described, and the challenges facing hybrid power systems, in addition, the most important of which are to build appropriate control systems for each application. Fast response and support it by two or more sustainable energy sources increase the reliability of power production combined with (HRES). This study comprehensively reviews ESS technologies types, ESS structures, classifications, and ESS merits and demerits in MG applications.

In this paper, Nelder-Mead simplex algorithm (NMA) is proposed to tune the optimal parameters of a proportional integral (PI) controller for the output voltage regulation of synchronous generator through different loading conditions. The model of the SG is related to diverse loads in two ways. Firstly, each load is related separately and secondly the SG loads change through the operation in order to guarantee the robustness of controller for large load deviations. In addition, parameters of the PI controller are obtained by minimization of the quadratic output error between the reference voltage and the terminal voltage of the generator calculated from the adopted model at the same time. Simulation results obtained by MATLAB and Simulink are investigated for output voltage regulation of SG without any controller at first, then with PI controller. In order to evaluate the performance of the NMA-PI controller, the results are compared with the Hooke and Jeeves (H&J) method. The comparison shows that the NMA tuned PI controller has better control performances versus the (H&J) method.
本文采用Nelder-Mead单纯形算法(NMA)对比例积分(PI)控制器在不同负载条件下的最优参数进行整定，实现同步发电机输出电压的调节。SG的模型与不同荷载有两种关系。首先，每个负载是单独关联的，其次，SG负载随着运行而变化，以保证控制器对大负载偏差的鲁棒性。此外，PI控制器的参数是通过最小化参考电压与发电机终端电压之间的二次输出误差来获得的。首先利用MATLAB和Simulink对无控制器的SG输出电压调节进行了仿真研究，然后采用PI控制器对SG输出电压进行了调节。为了评价NMA-PI控制器的性能，将结果与Hooke and Jeeves (H&J)方法进行了比较。比较表明，NMA调谐PI控制器比(H&J)方法具有更好的控制性能。

In this paper, we introduce a control approach using a quadratic polynomial expression of the controlled Poincaré Map to actively stabilize the passive walking motion of the two-degree-of-freedom compass-gait biped walker. The passive gait cycle of the bipedal walker is depicted for a given fixed point. The control of the passive gaits involves firstly the reconstruction of the nonlinear complex dynamics describing the passive bipedal walking into an amendable linear system around the period-1 limit cycle. It involves secondly the determination of the quadratic polynomial expression of the nonlinear controlled Poincaré Map, and finally the identification of its period-1 fixed point. Successively, to stabilize such fixed point, we develop the linearized Poincaré Map, which will be explored to design the feedback gain of the control law. The control problem is cast then into a convex optimization involving a linear matrix inequality (LMI) by maximizing the bound on the nonlinear term in the Poincaré map. Simulation outputs illustrate the efficiency of the adopted LMI-based optimization method in the control of the passive motion of the compass-gait walker.

The more common and economic way for increasing the power transfer capability of a transmission line is by installing capacitor banks that are connected in series with those lines. In such case, the transmission line is called a series compensated line. In general, all of electric components in AC power networks should have their own protection schemes, for instance the transmission lines are protected using the line current differential scheme or the communication aided distance scheme as a primary protection scheme, and in addition a conventional distance scheme (Modified impedance or Quadrilateral protective element) is used as a backup protection. So, installing capacitor banks in series with such lines will raise new challenges to the existent protection scheme of that line. This paper addresses these challenges when a series compensated transmission system needs to be protected from the AC faults or severed disturbances. Where, the most common challenges in series compensated transmission systems are: voltage inversion, current inversion, and sub-harmonic frequency oscillations. A chosen series compensated transmission system will be used as a model for performing this research study, and simulated results will be shown for this work. Finally, based on protection engineer point view the recommendations of the relay settings will be discussed to overcome most of these raised challenges in protecting the series compensated transmission system.

Hand gesture recognition presents one of the most important aspects for human machine interface (HMI) development, and it has a wide spectrum of applications including sign language recognition for deaf and dumb people. Herein, force myography signals (FMG) are extracted using eight nanocomposite CNT/PDMS pressure sensors simultaneously. Data are collected from eight healthy volunteers for American sign language digits 0–9. Two sets of features are extracted, the first one is composed of mean, standard deviation and rms values for the raw FMG data for all 8 sensors individually. The second set is composed of the 2-norm of the raw FMG signal and three proportional features, where the FMG signals are studied with respect to the reference rest signal. Classification is performed using each of the seven individual features as well as the combination of features in each set. The combination of features in the second set gives better testing accuracy of 95%, 91.9% for $mathrm{k}=2, mathrm{k}=3$ using KNN classifier, respectively.

Electrode materials play a critical role in the performance of microbial fuel cells. This study investigates the contribution of capacitive bio-electrodes to sustainable power production in a single-chamber microbial fuel cell (MFC). The capacitive electrodes consisted of a stainless-steel wire mesh with an activated carbon layer, while the non-capacitive control electrodes were made of graphite felt with a wound current collector. The MFCs were constructed using a glass vessel with the anode completely buried in biologically active soil and the cathode placed above the soil to form a single chamber configuration. The performance of the MFCs was investigated using linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS). The results showed that the performance of the capacitive MFC was three times better than that of the non-capacitive MFC. While there was no significant difference in the Ohmic resistances of the MFCs, there was a significant difference in charge transfer resistance and capacitance of the MFCs. The capacitive MFC had a double layer capacitance of $8.282 mu mathrm{F}$ in addition to the diffuse layer capacitance at the layer/metal interface of 2.012 F, while the non-capacitive MFC had a double layer capacitance of $5.034 mu mathrm{F}$ with no diffuse layer capacitance. The results show that the capacitive characteristics of both cathode and anode improve the performance of a single-chamber MFC.

In this paper, we propose a framework for image classification tasks, named MIC, that takes as input multi-view images, such as RGB-T images for surveillance purposes. We combine auto-encoder and generative adversarial network architectures to ensure the multi-view embedding in a common latent space. Then, the resulting features are fed to the classification stage. The proposed framework is able to, all at once, train the multi-view embedding model to find a shared latent representation for the different views, perform data imputation (generate the missing views) and ensure the classification task by predicting the labels. Experiments on the MNIST dataset with a panoply of classifiers and several missingness ratios show the effectiveness of our solution.
