According to the Ministry of Global Health, social distance is one of the most effective defenses against COVID-19 and helps to prevent its spread. Governments have imposed many safety orders on citizens and facilities to limit social distancing and slow the spread of the virus. As a result, there has been an increase in interest in technologies to research and control the spread of COVID-19 in various settings. This research aims to investigate the results of several machine learning approaches to find cases when the physical distance between people has been violated. The method first identifies the instance of the human in the video frame, tracks the movements, computes the distance with other humans on the same frame and thus estimates the number of people who violate the social distance. Compares the approach to performing the performance using Yolo, SSD and Faster R- CNN. Videos that are used in this approach are collected from the wild, considering different camera settings, indoor and outdoor scenes, and recorded from various angles. Comparing the three methods Yolo, SSD and Faster RNN, the results show Yolo has a better performance in detecting humans from the current videos and thus in determining the violation of the distance between humans.
根据全球卫生部的说法,社交距离是对抗COVID-19最有效的防御措施之一,有助于防止其传播。各国政府对公民和设施实施了许多安全命令,以限制社会距离,减缓病毒的传播。因此,人们对在各种环境中研究和控制COVID-19传播的技术越来越感兴趣。本研究旨在调查几种机器学习方法的结果,以发现人与人之间的物理距离被侵犯的情况。该方法首先识别视频帧中人的实例,跟踪其运动,计算与其他人在同一帧中的距离,从而估计违反社交距离的人数。比较使用Yolo, SSD和Faster R- CNN执行性能的方法。这种方式使用的视频是从野外采集的,考虑到不同的相机设置,室内和室外场景,从不同的角度记录。对比Yolo、SSD和Faster RNN三种方法,结果表明Yolo在从当前视频中检测人从而确定人之间距离违规方面具有更好的性能。

People with disabilities struggle to perform specific tasks throughout their daily life. However, BCI systems are developed to assist people struggling with motor impairment by transforming their thoughts into action. Non-invasive BCI systems use electroencephalogram (EEG) to record brain activities. In this study, we segment the EEG signals and then break the segment down into a few intrinsic mode functions using oscillation mode decomposition. Then the intrinsic mode functions are mined for feature extraction. The features mined are processed by different machine learning algorithms for categorization. Among the different algorithms, K-NN yielded the best results with an overall average accuracy score of 95.48%. This approach can be used in future to develop the brain driven metaverse interactive solutions.

Self-Balancing System and Control Design for Two-Wheeled Single-Track Vehicles 双轮单轨车辆自平衡系统及控制设计
Pub Date : 2023-01-26 DOI: 10.1109/LT58159.2023.10092328

This study presents a novel approach to achieve self-balance by employing a proportional integral derivative (PID) control system. Simply put, the innovative design consists of two electric ducted fans (EDF) that propel air against the direction of fall and thereby maintain balance. If these motors are allowed to move in two degrees of freedom, the EDF motors will propel and reduce weight of the two-wheeler while maintaining stability. To the best of our knowledge, no study has proposed a system that simultaneously provides propulsion and weight reduction along with achieving self-balance. The working mechanism of the utilized PID arducopter controller is elucidated which utilizes an IMU sensor and employs a nonlinear complementary filter on the special orthogonal group to determine the lean angles at any instant of time and a feedback loop to maintain the system’s position at the desired upright zero degrees lean angle. Next, the proposed PID controller is first tested on a small-scale model to validate the developed concept to achieve self-balance by employing EDF motors. After achieving successful results on the small-scale model and thereby attaining the step of validation, the proposed concept is tested against a full-scale model (motorbike) by designing the mechanical and electrical parts. The methodology is divided into three major steps – mechanical parts design and manufacture, electrical components design and control system design. Furthermore, three mechanisms are designed to control steering, braking and throttle via a remote transmitter receiver control and autonomous control.
本文提出了一种采用比例积分导数(PID)控制系统实现自平衡的新方法。简单地说,这个创新的设计由两个电动管道风扇(EDF)组成,它们推动空气朝着下降的方向前进,从而保持平衡。如果允许这些电机在两个自由度内移动,EDF电机将在保持稳定性的同时推动和减轻两轮车的重量。据我们所知,没有研究提出一个系统,同时提供推进和减轻重量,并实现自我平衡。阐述了所采用的PID直旋翼控制器的工作机理,该控制器采用IMU传感器,在特殊正交组上采用非线性互补滤波器确定任意时刻的倾斜角,并采用反馈回路使系统保持在期望的垂直零倾斜角位置。接下来,首先在一个小规模模型上测试所提出的PID控制器,以验证所开发的概念,通过使用EDF电机实现自平衡。在小规模模型上取得成功的结果,从而达到验证的步骤后,通过设计机械和电气部件,在全尺寸模型(摩托车)上测试所提出的概念。该方法分为机械零件设计与制造、电气元件设计和控制系统设计三个主要步骤。此外,设计了三种机制,通过远程发送接收器控制和自动控制来控制转向,制动和油门。

The Speech Emotion Recognition (SER) system is an approach to identify individuals' emotions. This is important for human-machine interface applications and for the emerging Metaverse. This work presents a bilingual Arabic-English speech emotion recognition system based on EYASE and RAVDESS datasets. A novel feature set was composed by using spectral and prosodic parameters to obtain high performance at a low computational cost. Different classification models were applied. These machine learning classifiers are Random Forest, Support Vector Machine, Logistic Regression, Multi-Layer Perceptron, and Ensemble learning. The proposed feature set performance was compared to the "Interspeech 2009" challenge feature set, which is considered a benchmark in the field. Promising results were obtained using the proposed feature sets. SVM resulted in the best emotion recognition rate and execution performance. The best accuracies achieved were 85% on RADVESS, and 64% on EYASE. Ensemble learning detected the valence emotion with 90% on RADVESS, and 87.6% on EYASE.

The spread of COVID-19 has thrown the world into a panic. We are constantly learning more about the virus every day, from how it spreads to who is more susceptible to becoming infected by different variants. Those with underlying respiratory conditions and other immunocompromised individuals need to be extra cautious regarding the virus. Many researchers have created COVID-19 trackers to detect the spread of COVID-19 around the world and show hot spots where COVID-19 cases are more prevalent. Previous work lacks the consideration of comorbidity as a factor of death rate. This work aims to create an agent-based model to predict comorbidity death rate caused by a health condition in addition to COVID-19. The model is evaluated using the symmetric mean absolute percentage error metric and proved to be very efficient.
新冠肺炎疫情的蔓延使世界陷入恐慌。我们每天都在不断地了解更多关于病毒的信息,从它如何传播到谁更容易被不同的变种感染。那些有潜在呼吸道疾病和其他免疫功能低下的人需要格外小心这种病毒。许多研究人员创造了COVID-19追踪器,以检测COVID-19在世界各地的传播情况,并显示COVID-19病例更普遍的热点地区。以往的研究缺乏将合并症作为死亡率因素的考虑。这项工作旨在创建一个基于agent的模型来预测除COVID-19外由健康状况引起的共病死亡率。采用对称平均绝对百分比误差度量对该模型进行了评价,证明了该模型是非常有效的。

The use of machine learning to forecast how nanoparticles would migrate through porous material is covered in this research. We employed the random forest, decision tree, artificial neural network, and gradient boosting regression machine learning techniques. Since there are not many experimental datasets available, it is easier to create artificial datasets using verified numerical simulators. Additionally, covered in the paper are data preprocessing, correlations, the importance of features, and hyperparameter adjustment. Moreover, different error metrics and R2-correlation are used to gauge how well the predictive models perform. Finally, examples of the findings are presented. The decision tree model is determined to have the highest accuracy, the best performance, and the lowest root mean squared error.

The rapidly increasing demand for mobile communication over satellite platforms and its applications necessitates a significant effort on the part of researchers to fulfill the prospective requirements of wireless network infrastructure. It is predicted that traffic will increase by multiples of hundreds soon. Therefore, the network's capacity has to multiply with high energy efficiency (EE), which can be achieved using massive multiple-input, multiple-output (M-MIMO). An adaptive scheme that maximizes energy efficiency is proposed in this paper at maximum spectral efficiency. Also, an efficient tradeoff between energy efficiency and throughput is mainly proposed. The analytical and simulation results prove that the proposed multi-cell minimum mean square error (M-MMSE) precoding scheme provides the maximum EE and efficient throughput of next-generation networks and satellite communication utilizing M- MIMO. Hence, it gives the optimum and most efficient tradeoff between EE and the throughput of the M-MIMO system.
卫星平台移动通信及其应用需求的快速增长,要求研究人员付出巨大的努力来满足无线网络基础设施的未来需求。据预测,交通流量很快将增加数百倍。因此,网络容量必须与高能效(EE)相乘,这可以通过大规模多输入多输出(M-MIMO)来实现。本文提出了一种能在最大频谱效率下实现能量效率最大化的自适应方案。此外,还提出了一种有效的能源效率和吞吐量之间的权衡。分析和仿真结果表明,所提出的多小区最小均方误差(M- mmse)预编码方案可为M- MIMO下一代网络和卫星通信提供最大的EE和高效吞吐量。因此,它在EE和M-MIMO系统的吞吐量之间给出了最佳和最有效的权衡。

Instant messaging applications enable users to communicate with each other in a simple and efficient manner. However, big corporations dominate and control the market today. This gives these corporations authority over their users and their data. Moreover, all popular instant messaging applications today rely on a set of centralised servers, introducing a single point of failure. The authors of this paper propose an instant messaging application that relies on a decentralised architecture, a first of its kind, hosted on the cloud, making the service fault-tolerant. Additionally, all messages being exchanged between users are End-to-End Encrypted, providing the users with privacy. The authors of this paper were able to demonstrate the proposed system working as envisioned.
即时消息应用程序使用户能够以一种简单而有效的方式相互通信。然而,大公司主导和控制着今天的市场。这赋予了这些公司对其用户和数据的权力。此外,当今所有流行的即时通讯应用程序都依赖于一组集中式服务器,这就引入了单点故障。这篇论文的作者提出了一个即时通讯应用程序,它依赖于一个分散的架构,这是同类中的第一个,托管在云上,使服务具有容错性。此外,用户之间交换的所有消息都是端到端加密的,为用户提供了隐私。本文的作者能够演示所提出的系统按预期工作。

In recent years, advances in technology in several industries have resulted in massive data collections on the web. It raises worries about large data security and protection. The advent of Blockchain technology has caused a revolution in the security field for different applications. The distributed ledger is stored on each Blockchain node, which enhances security and data transparency. On the Blockchain network, illegal users are not authorized to undertake any fault transactions. In this article, we will discuss how Blockchain may be employed to secure the big data. We explain the problems that the Blockchain faced with big data and its solutions. We summarize recent works of Blockchain with big data and the present issues and trends. We demonstrate that Blockchain technology is still in its initial phases of validation and there are no large-scale application scenarios available, particularly in the big data sector. Finally, we narrow our study to the Healthcare industry and offer the following research directions for its primary issues.
近年来,几个行业的技术进步导致了网络上大量的数据收集。这引发了人们对大数据安全和保护的担忧。区块链技术的出现引起了安全领域不同应用的革命。分布式账本存储在每个区块链节点上,增强了安全性和数据透明度。在区块链网络上,非法用户无权进行任何错误交易。在本文中,我们将讨论如何使用区块链来保护大数据。我们解释了区块链在大数据中面临的问题及其解决方案。我们总结了区块链在大数据方面的最新工作,以及当前的问题和趋势。我们证明,区块链技术仍处于验证的初始阶段,没有大规模的应用场景,特别是在大数据领域。最后,我们将研究范围缩小到医疗保健行业,并针对其主要问题提出以下研究方向。
