Hardware Implementation of Maximum Power Point Tracking Algorithms for Photovoltaic Systems: A comparative study 光伏系统最大功率点跟踪算法的硬件实现:比较研究
Z. Salah, Saber Krim, Mohamed Ali Hajjaji, A. Mtibaa, M. Mimouni
This paper presents a hardware implementation of Maximum Power Point Tacking (MPPT) algorithms for photovoltaic system using a Field Programmable Gate Array (FPAG). Firstly, a comparison between different MPPT algorithms in terms of efficiency and accuracy is studied in this paper. Secondly, the FPGA is suggested to overcome the software solutions limitations like microcontrollers and digital signal processors in terms sequential of processing, which increases the execution time and the sampling period of the system. In fact, if the sampling period increased the control loop delays raise which consequently affects the system performances. The FPGA has a hardware architecture that executes the control algorithm with very low execution time, thanks to its parallel processing. The architectures of the MPPT algorithms are carried out using a Vivado Xilinx System Generator (XSG) toolbox and implemented on an FPGA Zed-Board Zynq-7000.
提出了一种利用现场可编程门阵列(FPAG)实现光伏系统最大功率点跟踪(MPPT)算法的硬件实现方法。首先,本文对不同的MPPT算法在效率和精度方面进行了比较研究。其次,FPGA克服了微控制器和数字信号处理器等软件解决方案在处理顺序上的限制,增加了系统的执行时间和采样周期。实际上,如果采样周期增加,控制回路的延迟会增加,从而影响系统的性能。由于FPGA的并行处理,其硬件架构可以以极低的执行时间执行控制算法。MPPT算法的架构使用Vivado Xilinx System Generator (XSG)工具箱进行,并在FPGA Zed-Board Zynq-7000上实现。

Maximizing The Lifetime of WSN Using Hybrid Energy Harvesting Approach 利用混合能量收集方法最大化无线传感器网络的寿命
Boulerial Dalila, Kechar Bouabdellah, Benzerbadj Ali
The 21st century is marked by a remarkable expansion of IoT. This technology that allows us to connect with our objects permanently and thus monitor each interaction that may be crucial in our daily life. And among the most important bronchi of this technology we are interested in wireless sensor networks with mobile sink (WSN-MS1 for short). These networks, while being very useful and efficient in the world of internet of things (IoT)[33],[34], they face serious challenges, particularly that of the battery which ensures them a very limited lifetime, as well as the problem of the broken links between the transmitting nodes and the mobile sink. In this paper, we have proposed a new approach EH-HXMAC that solves the first problem by collecting ambient energy from the two most powerful sources (the sun and the wind), and by acting on the duty cycle of the emitting nodes. To remedy the second problem, we have resorted to the Handover technique which ensures data transmission integrity between the sensor and the mobile sink. The results of the simulation carried out by the Cooja Contiki simulator show that the combination of these three techniques provides an improvement in terms of network lifetime , throughput and received packets number.
21世纪的标志是物联网的显著扩张。这项技术使我们能够永久地与我们的物体连接,从而监控我们日常生活中可能至关重要的每一次互动。在这项技术最重要的分支中,我们对带有移动接收器的无线传感器网络(简称WSN-MS1)感兴趣。这些网络虽然在物联网(IoT)世界中非常有用和高效[33],[34],但它们面临着严峻的挑战,特别是确保它们非常有限的使用寿命的电池,以及传输节点和移动接收器之间链路断开的问题。在本文中,我们提出了一种新的EH-HXMAC方法,通过从两个最强大的来源(太阳和风)收集环境能量,并通过作用于发射节点的占空比来解决第一个问题。为了解决第二个问题,我们采用了确保传感器和移动接收器之间数据传输完整性的切换技术。在Cooja Contiki模拟器上进行的仿真结果表明,这三种技术的结合在网络生存期、吞吐量和接收包数方面都有改善。

Review and evaluation of OTP-Based authentication schemes in the metering systems of smart grids 智能电网计量系统中基于otp的认证方案综述与评价
Hind El Makhtoum, Youssef Bentaleb
Metering systems in smart grids are the components that store, transmit and process critical data about customers and their energy use. These systems communicate with users’ devices, technicians, and utility control systems, namely MDMS, substations… Consequently, smart meters are a tempting target for intrusion and falsification attacks that may have devastating consequences on the electrical grid and user’s private life. In order to tackle eventual vulnerabilities, the One-Time-Password (OTP) is a promising technique to ensure privacy and access control to smart meters as it is claimed to have better results on safeguarding access. In this paper, we highlight the current existing OTP-based authentication approaches in the metering systems. First, we investigate the privacy issues that are related to smart meters. Additionally, we highlight significant attacks and security parameters that we will include in our evaluation. Furthermore, we will analyze the selected schemes and propose some recommendations. Finally, we will discuss limitations, challenges, and future scopes of the analyzed schemes to help future researchers use the OTP technique securely and efficiently.

Sawssen Bacha, O. Taouali, N. Liouane
Cancer is one of the deadliest diseases for human health. The classification of cancers poses many challenges in biomedical research because it allows an accurate and effective diagnosis and guarantees the success of medical treatments. In this paper, a new reduced Computer-Aided Diagnosis (CAD) system is implemented under the MATLAB (version R2016a) environment to classifying four cancer subtypes. The results of the experiment are carried out with four sets of baseline data on the expression of cancer genes. To validate the proposed CAD system, different performance metrics such as sensitivity, specificity, accuracy, and F-Score are measured. The experimental analysis justifies the effectiveness of the proposed model and, therefore, this model can be considered as an effective tool to help radiologists for a better diagnosis.

Robust Real-time Automatic Voice Command based on Raspberry pi for assistance disabled people 鲁棒实时自动语音命令基于树莓派的援助残疾人
A. Mnassri, Sihem Nasri, Mohamed Boussif, A. Cherif
Walkers are widely used by people with limited mobility. Much research work is underway to design human-machine interfaces (HMIs) using physiological signals to improve the control of mechanical mobility devices, mainly wheelchairs. Generating exact control commands through physiology in a suitable HMI is a real challenge because severely disabled people cannot control classic wheelchairs. In this context, this work develops a new voice-signal control system to meet the needs of this physically disabled population. This system is divided into two parts: part one covers the recognition, processing and classification of speech signals in this part the relative spectral-perceptual linear prediction (RASTA-PLP) and discrete wavelet transform (DWT) are combined to process and extract speech features and the second part includes the mechanical collection module, i. e. the wheelchair control by a motor drive circuit. The microphone servers for real-time voice recording. A Raspberry-Pi with a Linux operating system kernel is used as the processor. In order to make the processor more user-friendly and reliable, Voice-received mode is integrated into the Wheelchair. The model works successfully with an average recognition of 100 in clean environment and between 80 and 100 in noisy environment.
助行器被行动不便的人广泛使用。利用生理信号设计人机界面(hmi)来改善对机械移动设备(主要是轮椅)的控制,目前正在进行大量的研究工作。在一个合适的人机界面上通过生理学产生精确的控制命令是一个真正的挑战,因为严重残疾的人无法控制传统的轮椅。在此背景下,本工作开发了一种新的语音信号控制系统,以满足这些肢体残疾人群的需求。本系统分为两部分:第一部分是语音信号的识别、处理和分类,其中结合相对频谱感知线性预测(RASTA-PLP)和离散小波变换(DWT)对语音特征进行处理和提取,第二部分是机械采集模块,即电机驱动电路控制轮椅。用于实时录音的麦克风服务器。使用带有Linux操作系统内核的树莓派作为处理器。为了使处理器更加人性化和可靠,轮椅集成了语音接收模式。该模型在清洁环境下的平均识别率为100,在噪声环境下的平均识别率为80 ~ 100。

Efficient Serial Architecture for PRESENT Block Cipher 分组密码的高效串行结构
Ayoub Mhaouch, W. Elhamzi, A. B. Abdelali, Mohamed Atri
In recent years, the use of the Internet of Things (IoT) has increased rapidly in different areas. Due to many IoT applications, many limitations have emerged such as power consumption and limited resources. The security of connected devices is becoming more and more a primary need for the reliability of systems. Among other things, power consumption remains an essential constraint with a major impact on the quality of the encryption system. For these, several lightweight cryptography algorithms were proposed and developed. The PRESENT algorithm is one of the lightweight block cipher algorithms that has been proposed for a highly restrictive application. In this paper, we have proposed an efficient hardware serial architecture that uses 16 bits for data path encryption. It uses fewer FPGA resources and achieves higher throughput compared to other existing hardware applications.

Xinbao Zhang, Shan-shan Yong, Xin'an Wang, Chunjiu He, Zhenyu Bao, Yibin Liu
Earthquakes are closely related to fault zones, and regular monitoring of the activity of fault zones is of great significance to the earthquake prediction of surrounding areas. The existing earthquake precursor monitoring device is mainly of fixed station type, with high deployment cost and difficulty in moving. To solve these problems, this work proposes a mobile monitoring system F-AETA, which collects high-precision and real-time earthquake precursor data. With these collected data we can analyze the direction and distribution of fault zones, and evaluate the earthquake risk of surrounding areas routinely.

In the last decades, brain tumors are considered one of the mortal cancers in the world. The right tumors detection and identification in the early phases have a significant role to select an accurate treatment. Due to the increasing number of patients and brain tumor types, the manual analyses of Magnetic Resonance Imaging (MRI) images represent a tiring routine and can lead to human errors. In the goal to surpass these problems, an automatic CAD system is needed. We discussed, in this paper, a new model to classify brain tumors using CNN. The suggested scheme is experimentally evaluated on a public dataset. The proposed approach yields a convincing performance compared to previous techniques based on the experimental results.
在过去的几十年里,脑瘤被认为是世界上最致命的癌症之一。早期正确的肿瘤检测和识别对于选择正确的治疗方案具有重要意义。由于患者数量和脑肿瘤类型的增加,人工分析磁共振成像(MRI)图像是一项累人的工作,可能导致人为错误。为了超越这些问题,需要一个自动化的CAD系统。本文讨论了一种利用CNN对脑肿瘤进行分类的新模型。该方案在一个公共数据集上进行了实验评估。实验结果表明,与以往的方法相比,该方法具有令人信服的性能。
