Despite the immense use of single Unmanned Aerial Vehicle (UAV) systems in various applications, it is not yet able to cover large areas with optimized energy consumption. Accordingly, Flying Ad-hoc Network (FANET), as a collaborative groups of UAV s, is tremendously employed in recent research works allowing larger coverage and efficient monitoring. To ensure a secure FANET control, Software-Defined Networking (SDN) based solutions are frequently considered. This work presents and compares the recent SDN-based solutions proposed to reinforce FANET security and reduce its attacks. In addition, open research issues are highlighted with respect to SDN-FANET challenges.
尽管单个无人机系统在各种应用中被广泛使用,但它尚未能够覆盖大面积并优化能耗。因此,飞行自组织网络(FANET)作为一种由无人机组成的协作网络,在最近的研究工作中得到了广泛的应用,可以实现更大的覆盖范围和更有效的监测。为了确保安全的FANET控制,经常考虑基于软件定义网络(SDN)的解决方案。这项工作介绍并比较了最近提出的基于sdn的解决方案,以加强FANET的安全性并减少其攻击。此外,关于SDN-FANET挑战的开放研究问题也得到了强调。

The affordability and miniaturization of sensors create a revolution in wearable wireless solutions deployed to collect physiological parameters to assist in diseases/disorders diagnosis. Electroencephalography (EEG), a recording of the brain's electrical activity, is a promising physiological measure for autism spectrum disorder detection. It can reveal the irregularity of the neural system that is associated with autism. Wireless sensors represent a suitable infrastructure that can be deployed for signal transmission to the processing center. However, streaming EEG signals remotely for classification could shorten the lifetime of the wireless sensor and might question the viability of the application. Therefore, reducing the data transmission might preserve the sensor's energy and increase the wireless sensor network lifetime. This paper proposes the design of a sensor-based scheme for early-age autism detection in children. The proposed scheme uses low-complexity algorithms for on-node EEG processing, relevant features extraction and classification. The proposed processing scheme of the EEG signal is based on Haar wavelet transform and dynamics features. The experimental results show 93% accuracy, 86% sensitivity, and 100% specificity.
传感器的可负担性和小型化为可穿戴无线解决方案带来了一场革命,这些解决方案用于收集生理参数以协助疾病/障碍诊断。脑电图(EEG)是一种记录大脑电活动的方法,是检测自闭症谱系障碍的一种很有前途的生理测量方法。它可以揭示与自闭症有关的神经系统的不规则性。无线传感器代表了一种合适的基础设施,可以部署用于信号传输到处理中心。然而,远程流式传输EEG信号进行分类可能会缩短无线传感器的使用寿命,并可能质疑该应用的可行性。因此,减少数据传输可以节省传感器的能量,提高无线传感器网络的使用寿命。本文提出了一种基于传感器的儿童早期自闭症检测方案。该方案采用低复杂度算法进行节点上脑电信号处理、相关特征提取和分类。提出了基于Haar小波变换和动态特征的脑电信号处理方案。实验结果显示准确率为93%,灵敏度为86%,特异性为100%。

Vehicular Ad-hoc Network (VANET) is a primary part of Intelligent Transportation System (ITS). VANETS provides mechanisms for vehicles to communicate with road side units (RSUs). This information represents past data and predicts upcoming events. The emergence of Neural Networks (NNs) and its variants can simulate learning model for future prediction. Utilizing vehicular network and recognition property of neural network, it is now possible to analyze data of real-time driving and road conditions to predict future traffic condition. This system can be used for traffic monitoring, accident prediction or road hazard detection. In this paper, a detailed survey is provided about use of neural networks for prediction purposes in VANETs.

Distributed denial of service (DDoS) cyber-attack poses a severe threat to the industrial Internet of Things (IIoT) operation due to the security vulnerabilities resulted from increased connectivity and openness, and the large number of deployed low computation power devices. The aim of this paper is to provide a solution to the application-level DDoS attack, which is increasingly difficult to detect because botnets tend to get confused with various legitimate users. The proposed solution aims to study the behavior of users and bots, through a User Behavior Analytics (UBA) solution by using Long Short-Term Memory (LSTM) neural networks to provide a potentially ideal solution to mitigate this type of attack. Accuracy, precision and recall were used to evaluate the model. The values of the three metrics resulting from the training of the model are all very high, which makes us understand that the model reacts well to illicit users but at the same time it does not exchange the licit users for malicious ones.
分布式拒绝服务(DDoS)网络攻击对工业物联网(IIoT)的运营造成了严重的威胁,因为工业物联网的连通性和开放性越来越高,并且大量部署了低计算能力的设备。本文的目的是为应用级DDoS攻击提供一种解决方案,这种攻击越来越难以检测,因为僵尸网络往往与各种合法用户相混淆。提出的解决方案旨在研究用户和机器人的行为,通过使用长短期记忆(LSTM)神经网络的用户行为分析(UBA)解决方案,为减轻这种类型的攻击提供潜在的理想解决方案。用准确度、精密度和召回率对模型进行评价。通过模型的训练得到的三个指标的值都很高,这让我们理解了模型对非法用户的反应很好,但同时也没有将合法用户换成恶意用户。

The fabric pattern recognition and subsequently the classification is an imperative task in textiles. Currently, this is done manually, therefore, the need of the requirement is to develop a system that could recognize and classify the fabric weave patterns for ease of inspection and storage. The classification of woven fabrics in today's textile industry is generally manual, requiring significant human effort and a long time. Automatic and effective approaches for woven fabric classification are desperately required with the rapid development of computer vision. This paper proposes an automated and real-time classification technique to analyze three woven fabrics: plain, twill, and satin weave. To achieve the objective, ResNet pre-trained Convolutional Neural Network architecture is used for classification. To obtain texture characteristics, the gray-level co-occurrence matrix and Gabor wavelet, are included in the technique. To eliminate redundancy and maximize main component feature vectors, Principal component analysis is then used to select feature vectors. The experimental result shows that with quicker training speed, the Deep CNN classifier can reliably and efficiently identify woven fabrics. Deep Convolutional Neural Network provides the best accuracy 96.15%.
织物的模式识别和分类是纺织领域的一项重要任务。目前,这是手工完成的,因此,需求的需要是开发一个系统,可以识别和分类织物的编织模式,以方便检查和存储。当今纺织工业中机织物的分类一般是手工的,需要大量的人力和较长的时间。随着计算机视觉技术的飞速发展,迫切需要一种自动有效的机织物分类方法。本文提出了一种自动实时分类技术来分析三种机织物:平纹、斜纹和缎纹。为了实现这一目标,使用ResNet预训练的卷积神经网络架构进行分类。该方法采用灰度共生矩阵和Gabor小波来获取纹理特征。为了消除冗余并最大化主成分特征向量,采用主成分分析方法选择特征向量。实验结果表明,在训练速度较快的情况下,Deep CNN分类器能够可靠、高效地识别机织物。深度卷积神经网络的准确率为96.15%。

The multicellular midpoint inverter is an intriguing situation; it is made up of p switching cells isolated by p-1 floating capacitors. This inverter's voltage levels provide frequent advantages and allow it to gain a good current source of excellent quality. This work offers a fuzzy logic - cyclic reports modulation control to improve the output power quality of a one phase series five-cell inverter, which is based on the converter's average model. To keep the capacitor voltages close to their references, the cyclic reports modulation approach is used. Keeping in mind that this command only ensures the regulation of the capacitor voltages, the output current regulation is also ensured in this study by incorporating a fuzzy logic controller. The suggested method is compared to the conventional proportional-integral regulator and the natural balancing strategy. The simulation results demonstrate that the five-cell inverter topology and proposed control result in good performance.
多蜂窝中点逆变器是一个有趣的研究领域;它由p-1浮动电容器隔离的p个开关电池组成。这种逆变器的电压水平提供了频繁的优势,并允许它获得优秀质量的良好电流源。本文提出了一种基于变换器平均模型的模糊逻辑循环报告调制控制,以改善单相串联五单元逆变器的输出电能质量。为了使电容器电压接近参考电压,采用了循环报告调制方法。考虑到该命令仅保证了对电容器电压的调节,本研究还通过加入模糊逻辑控制器来保证输出电流的调节。将该方法与传统的比例积分调节器和自然平衡策略进行了比较。仿真结果表明,五单元逆变器拓扑结构和所提出的控制方法具有良好的性能。

Unmanned Aerial Vehicles (UAVs) now play critical roles in a wide range of real-world applications and improving their control performance has become an increasingly appealing research topic. The goal of this paper is to solve the problem of controlling UAVs subject to external disturbances to maintain the desired trajectory while ensuring reliable and rapid convergence to the actual values. This paper presents a novel approach for the design and stability analysis of an adaptive trajectory tracking control for a multi-rotor UAV. UA V controllers are divided into two parts: position controllers and attitude controllers. A new Linear Parameter Varying Model Predictive Controller (LPV -MPC) is designed for attitude controller stabilization and quick tracking of the desired values of the Euler angles. The position controller is in charge of the position variables., which are calculated using the adaptive backstepping method and the targeted reference trajectory. The Lyapunov theory is utilized to prove the stability of the UAV's position controller. Finally., simulation results are provided., which demonstrates the effectiveness of the proposed control framework against disturbances.

Pulse width modulation (PWM) rectifiers are among the best solutions for improving the electrical power transfer quality from a source to a receiver. In fact, some authors have presented several methods for controlling the three-phase PWM rectifier and eliminating total harmonic distortion to achieve an uncontaminated system operating within a unit power factor. This article focuses on the sliding mode method, which is based on data from two or three line current sensors and a DC link voltage sensor, as well as the development of the most modern network voltage controllers, which include a sliding mode regulator for the system. The simulation results demonstrate the viability and reliability of the observer's sliding mode methodology in a transient and stable state with a quasi-sinusoidal low total harmonic distortion (THD) line current source and a good maintenance of the reference voltage on the same day, in the DC side of the PWM rectifier, in accordance with standards.
脉宽调制(PWM)整流器是改善电源到接收器的电能传输质量的最佳解决方案之一。事实上,一些作者已经提出了几种控制三相PWM整流器和消除总谐波畸变的方法,以实现在单位功率因数内运行的无污染系统。本文重点介绍了基于两线或三线电流传感器和直流链路电压传感器数据的滑模方法,以及最现代的网络电压控制器的开发,其中包括系统的滑模调节器。仿真结果表明,在准正弦低总谐波失真(THD)线电流源和参考电压维持良好的情况下,该观测器滑模方法在暂态和稳定状态下的可行性和可靠性,在PWM整流器直流侧,符合标准。

This study aims to improve the automatic detection of epileptic seizures (ESs) using machine learning (ML) algorithms applied to electroencephalography (EEG) brainwave data. Previous studies based on a database published online showed high seizure detection accuracies, but they contrasted seizure activity to all kinds of non-seizure EEG activity, recorded from different populations (healthy and patient) and different types of electrodes (surface and intracranial). Here we decided to focus on detecting seizures from non-seizure activity recorded from the same type of electrodes in the same group of patients. We applied different ML classifiers such as Extreme Gradient Boosting (XgBOOST), Naive Bayes (NB), k-Nearest Neighbor (k-NN), Random Forest (RF), Support Vector Machine (SVM), Linear Regression (LR), and Decision Tree (DT). The best Area Under Curve (AUC) value is given by XgBOOST with 95.84%. This research helps to improve the detection of human ES in EEG signal recordings.
本研究旨在利用应用于脑电图(EEG)脑电波数据的机器学习(ML)算法改进癫痫发作(ESs)的自动检测。先前基于在线发布的数据库的研究显示了较高的癫痫检测准确性,但他们将癫痫活动与所有非癫痫性脑电图活动进行了对比,这些活动记录于不同人群(健康和患者)和不同类型的电极(表面和颅内)。在这里,我们决定将重点放在从同一组患者的同一类型电极记录的非癫痫活动中检测癫痫发作上。我们应用了不同的机器学习分类器,如极端梯度增强(XgBOOST)、朴素贝叶斯(NB)、k-最近邻(k-NN)、随机森林(RF)、支持向量机(SVM)、线性回归(LR)和决策树(DT)。最佳的曲线下面积(AUC)值为XgBOOST的95.84%。本研究有助于提高对脑电信号记录中人体ES的检测。
