In the Beyond 5G (B5G) era, a paradigm shift from technical Quality of Service (QoS) oriented networks to user-centric Quality of Experience (QoE) centred network architectures is expected to occur. With this development, the infusion of QoE user requirements into B5G networks will be critical to the emergence of ultra-reliable and ultra-low latency haptic-enabled Internet applications of the future. One such application which will signify the emergence of a tele-haptic Internet will be the mission-critical use case of remote robotic surgical task performance, precipitating a transition from content-based to skillset delivery networks for an augmented user experience. In extending network QoS to user focused QoE and with it, Quality of Task (QoT) dimensions, human users in a global control loop (such as robotic surgeons) will be capable of true-to-life immersive remote task performance through the manipulation of objects in real-time and across large geographical distances. In this paper, we discuss the linkages between network and user-centric QoS and QoE (with QoT) perspectives. Further, we explain the emergence of a future B5G network and haptic-enabled Internet of Skills (IoS), and draw on the example of an architecture applied to the task-sensitive mission-critical use case of tele-haptic surgery. In doing so, we conceptualise and present Task-Technology Fit (TTF) theoretical and predictive modelling that can be empirically applied to this futuristic use case for a novel QoE/QoT perspective of future B5G communication networks.
在超越5G (B5G)时代,预计将发生从面向技术的服务质量(QoS)网络向以用户为中心的体验质量(QoE)网络架构的范式转变。随着这一发展,将QoE用户需求注入B5G网络将对未来超可靠和超低延迟触觉互联网应用的出现至关重要。一个这样的应用将标志着远程触觉互联网的出现,这将是远程机器人手术任务执行的关键任务用例,加速从基于内容到技能交付网络的过渡,以增强用户体验。在将网络QoS扩展到以用户为中心的QoE及其任务质量(QoT)维度时,全球控制回路中的人类用户(如机器人外科医生)将能够通过实时和跨越大地理距离的对象操作来实现逼真的沉浸式远程任务性能。在本文中,我们讨论了以网络和用户为中心的QoS和QoE(与QoT)观点之间的联系。此外,我们解释了未来B5G网络和触觉技能互联网(IoS)的出现,并借鉴了应用于远程触觉手术任务敏感任务关键用例的架构示例。在此过程中,我们概念化并提出了任务技术匹配(TTF)理论和预测模型,这些模型可以经验地应用于未来B5G通信网络的新颖QoE/QoT视角的未来用例。

Since gold prices influence international economic and monetary systems, numerous studies have been conducted to forecast gold prices. Nonetheless, studies employing the linear relationship method usually fail to explain the change in the pattern of the gold price. This study introduces a new paradigm that incorporates association rules and long short-term memory (LSTM) as a nonlinear-based method. For simulation, the proposed method was analyzed with data from Yahoo Finance from January 2010 to December 2020. The association rule was used to choose features relevant to the gold spot (GS) in the US Dollar Index (DXY). The LSTM forecast the gold price with a range of hyperparameter settings. The simulation results showed that the proposed method—the LSTM with GS and DXY, or LSTM-GS-DXY—resulted in low mean absolute percentage error (MAPE) metrics. In addition, the proposed LSTM-GS-DXY system outperformed the simple moving average (SMA), weight moving average (WMA), exponential moving average (EMA), and auto-regressive integrated moving average (ARIMA).
由于黄金价格影响着国际经济和货币体系,人们进行了大量的研究来预测黄金价格。然而,采用线性关系方法的研究往往不能解释黄金价格格局的变化。本研究提出了一种结合关联规则和长短期记忆(LSTM)作为非线性基础方法的新范式。为了进行仿真,采用Yahoo Finance 2010年1月至2020年12月的数据进行分析。使用关联规则选择与美元指数(DXY)中黄金现货(GS)相关的特征。LSTM通过一系列超参数设置来预测黄金价格。仿真结果表明,该方法(LSTM-GS-DXY)具有较低的平均绝对百分比误差(MAPE)指标。此外,所提出的LSTM-GS-DXY系统优于简单移动平均(SMA)、加权移动平均(WMA)、指数移动平均(EMA)和自回归综合移动平均(ARIMA)。

Edge Intelligence has become increasingly popular and has already made its place to increase the overall system performance by reducing the burden of the cloud and the network. In edge intelligent frameworks, a massive amount of data generated are not provided to the central cloud, and data analysis is carried out at the edge. Edge intelligence IoT environments comprise heterogeneous devices that communicate over the network, making it essential to protect the data and users’ information. Through these edge frameworks, numerous users and devices take part in communication where the exchange of sensitive data occurs. Therefore, security in such frameworks is crucial and a key challenge for reliable communication. This paper performs an analysis of popular AI/ML applications toward edge intelligence focusing on highlighting the critical security and privacy concerns desired in such systems. After a thorough investigation, we show that although several promising edge intelligent frameworks have been developed to address energy and performance issues, they do not consider the security and privacy of the data as the researchers are more focused on the performance predicaments.
边缘智能已经变得越来越流行,并且已经通过减少云和网络的负担来提高整体系统性能。在边缘智能框架中,产生的大量数据不提供给中心云,数据分析在边缘进行。边缘智能物联网环境包括通过网络通信的异构设备,因此保护数据和用户信息至关重要。通过这些边缘框架,许多用户和设备参与到发生敏感数据交换的通信中。因此,此类框架中的安全性至关重要,也是可靠通信的关键挑战。本文对面向边缘智能的流行AI/ML应用程序进行了分析,重点强调了此类系统中所需的关键安全和隐私问题。经过彻底的调查,我们表明,尽管已经开发了几个有前途的边缘智能框架来解决能源和性能问题,但它们没有考虑数据的安全性和隐私性,因为研究人员更关注性能困境。

Background: COVID-19 is a major public health emergency wreaking havoc on public health, happiness, and liberty of travel, as well as the worldwide economy. Scientists from all over the world are working to develop treatments and vaccines; the WHO has given emergency approval to eight vaccines from around the world. However, it is also seen that the efficiency of vaccines is not up to the mark in different age groups. COVID-19 symptoms come in many different shapes and sizes, so it’s important to learn about them as soon as possible so that medical attention and management can be easier.Method: The GitHub Data Repository-made COVID-19 patient data is available on the internet, which is used in this investigation. We have used the association rule mining method to look for common patterns in a targeted class or segment and then look at the symptoms based on them.Result: The result is that this study involves individuals with a median age of 52 years old. Few frequent symptoms like respiratory failure (1%), septic shock (1.4%), respiratory distress syndrome (1.8%), diarrhoea (1.8%), nausea (2%), sputum (3%), headache (5%), sore throat (8%), pneumonia (8%), weakness (7%), malaise/body pain (11%), cough (37%), fever (67%) and remaining diseases like myocardial infarction, cardiac failure, and renal illness (less than 1%) were present. If a patient had chronic disease, respiratory failure, and pneumonia, there was a higher risk of death; if a patient had a combination of chronic disease, respiratory failure, and pneumonia, respiratory failure in the age range of 45 to 84 years there was a higher risk of death. Patients having chronic conditions like pneumonia or renal disease symptoms that died as a result of the corona virus had more serious indication patterns than those without chronic diseases.
背景:2019冠状病毒病是一场重大突发公共卫生事件,对公众健康、幸福、旅行自由以及全球经济造成严重破坏。来自世界各地的科学家正在努力开发治疗方法和疫苗;世界卫生组织紧急批准了来自世界各地的八种疫苗。然而,也可以看出,疫苗的效率在不同年龄组中并不达标。COVID-19的症状有许多不同的形状和大小,因此尽快了解它们很重要,这样就可以更容易地进行医疗护理和管理。方法:本次调查使用互联网上GitHub数据库提供的COVID-19患者数据。我们使用关联规则挖掘方法来查找目标类或部分中的常见模式,然后查看基于它们的症状。结果:结果是这项研究涉及的个体中位年龄为52岁。少数常见症状,如呼吸衰竭(1%)、感染性休克(1.4%)、呼吸窘迫综合征(1.8%)、腹泻(1.8%)、恶心(2%)、痰(3%)、头痛(5%)、喉咙痛(8%)、肺炎(8%)、虚弱(7%)、不适/身体疼痛(11%)、咳嗽(37%)、发烧(67%)和其他疾病,如心肌梗死、心力衰竭和肾脏疾病(不到1%)。如果患者患有慢性疾病、呼吸衰竭和肺炎,则死亡风险较高;如果患者同时患有慢性疾病、呼吸衰竭和肺炎,年龄在45岁到84岁之间的呼吸衰竭患者死亡的风险更高。患有肺炎或肾脏疾病等慢性疾病的患者因冠状病毒而死亡,其适应症模式比没有慢性疾病的患者更严重。

In 5G and beyond 5G wireless communication networks, the NOMA scheme is widely considered a major non-orthogonal access technique for improving system capacity and data rates. The main challenges in current NOMA systems are limited channel feedback and the difficulty of integrating it with advanced adaptive coding and modulation algorithms. This study analyses S-LSTM-based DL NOMA receivers in i.i.d. Nakagami-m fading channel circumstances as opposed to previously presented solutions. The LSTM has the advantage of responding dynamically to changing channel conditions. When compared to a typical NOMA system, a typical NOMA system has a 12% lower outage probability, a 39% increase in net throughput, and a maximum SER reduction of 48%. Complex modulated M-ary PSK and M-ary QAM data symbols are employed in D/L NOMA transmission. Classic receivers such as LS and MMSE are outperformed by the S-LSTM-based DL-NOMA receiver. The CP and non-linear clipping noise simulation curves compare the performance of the MMSE and LS receivers with that of the DL NOMA receiver in real-time propagation circumstances. The DL-based detector outperforms the MMSE for SNRs greater than 15 dB because the S-LSTM method is more robust than the clipping noise.
在5G及5G以上的无线通信网络中,NOMA方案被广泛认为是提高系统容量和数据速率的主要非正交接入技术。当前NOMA系统面临的主要挑战是有限的信道反馈以及难以将其与先进的自适应编码和调制算法集成。本研究分析了在i.i.d Nakagami-m衰落信道情况下基于s - lstm的DL NOMA接收机,而不是之前提出的解决方案。LSTM具有动态响应不断变化的信道条件的优点。与典型的NOMA系统相比,典型的NOMA系统的停机概率降低了12%,净吞吐量增加了39%,最大SER降低了48%。在D/L NOMA传输中采用复调制的m - mary PSK和m - mary QAM数据符号。LS和MMSE等经典接收器的性能优于基于s - lstm的DL-NOMA接收器。通过CP和非线性裁剪噪声仿真曲线比较了MMSE和LS接收机与DL NOMA接收机在实时传播环境下的性能。基于dl的检测器在信噪比大于15 dB时优于MMSE,因为S-LSTM方法比裁剪噪声更具鲁棒性。

Localization in modern and future wireless networks has been established as an important field of research work due to the requirements of location-based applications and services with variety of accuracy requirements. These are driven by the strong heterogeneity in terms of processing power, size and range of the nodes in beyond Fifth Generation (5G) telecommunications. Thus, localization methods in cellular and heterogeneous networks (Het-Nets) diversify in their application scenario (terrestrial and based on aerial platforms) and bands (licensed and unlicensed). They are categorized, according to the methodology used to perform the positioning, into three groups – fingerprinting (learning-based location estimation), trilateration and triangulation (distance or angular based), and hybrid (combining two geometric features of the received signals) methods. For each category, a summary of the methods’ design features and achieved accuracy is presented in tabular form. On the basis of the review, directions for future research are outlined, that will facilitate the further advancements in the design and application of localization methods for wireless communications.
由于基于位置的应用和服务的各种精度要求,定位已成为现代和未来无线网络中的一个重要研究领域。这是由处理能力、第五代(5G)以上电信节点的大小和范围等方面的强大异质性所驱动的。因此,蜂窝和异构网络(Het-Nets)中的定位方法在其应用场景(地面和基于空中平台)和频段(许可和非许可)上多样化。根据用于执行定位的方法,它们分为三组-指纹(基于学习的位置估计),三边测量和三角测量(基于距离或角度)和混合(结合接收信号的两种几何特征)方法。对于每一类,方法的设计特点和达到的精度的总结以表格形式呈现。在此基础上,展望了未来的研究方向,以促进无线通信定位方法的设计和应用的进一步发展。

Current advancements of Fifth Generation (5G) of mobile communications and beyond, have envisioned future networks as highly dense and coexisting in various bandwidths, providing seamless connectivity to users at any location. Thus, it is important to describe the effects and limits of densification and spectrum sharing. This article examines a less explored system model of a terrestrial cognitive radio (CR) based ultra-dense network (UDN) that operates within the range of a cellular macro base station (BS) and its users. It shares the incumbent spectrum in the interweave mode to avoid interference to the primary network, by implementing two common methods for energy detection (ED) spectrum sharing – Gaussian ED and Fading ED (FED). Through extensive simulations, the critical density of the UDN’s cognitive access points (CAPs), the ED efficiency, as well as the throughput gains, are determined through the measured signal-to-noise-ratio (SNR) at the CAPs and SUs. Additionally, the influence of different SU densification on the throughput is analyzed for the critical CAP density. It has been assessed that due to the high path loss in UDNs, the spectrum utilization gain (SUG) is small, but it may be improved through appropriate SU densification.
目前第五代移动通信(5G)及以后的进展,已经将未来的网络设想为高度密集并在各种带宽下共存,为任何位置的用户提供无缝连接。因此,描述致密化和频谱共享的影响和限制是很重要的。本文研究了一个较少探索的基于地面认知无线电(CR)的超密集网络(UDN)系统模型,该网络在蜂窝宏基站(BS)及其用户的范围内运行。通过实现两种常见的能量检测(ED)频谱共享方法——高斯ED和衰落ED (FED),在交织模式下共享现有频谱,避免对主网的干扰。通过广泛的模拟,UDN的认知接入点(CAPs)的临界密度、ED效率以及吞吐量增益,通过测量cap和su的信噪比(SNR)来确定。此外,针对临界CAP密度,分析了不同SU密度对吞吐量的影响。据评估,由于udn的高路径损耗,频谱利用增益(SUG)很小,但可以通过适当的SU密度来提高。

Through extensive simulations, the critical density of the UDN’s cognitive access points (CAPs), the ED efficiency, as well as the throughput gains, are determined through the measured signal-to-noise-ratio (SNR) at the CAPs and SUs. Additionally, the influence of different SU densification on the throughput is analyzed for the critical CAP density. It has been assessed that due to the high path loss in UDNs, the spectrum utilization gain (SUG) is small, but it may be improved through appropriate SU densification.","PeriodicalId":425561,"journal":{"name":"J.

Theme, background and signal music is the music inserted into broadcasting contents of a broadcaster, and is recognized as a created content like normal music. Since there are lyricists and composers who have the rights of music, the copyright fee is distributed. However, there often occur problems with inaccurate monitoring results for theme, background and signal music usage due to the omission of usage details and non-transparent settlement method. In this paper, we propose a method of generating music usage monitoring information based on a blockchain, on which the usage information of music source is recorded by the usage monitoring tool based on the feature-based filtering technology of monitoring organizations. The framework proposed in this paper includes a blockchain network structure, a series of transaction procedures in which the theme, background and signal music usage history is stored and the recorded data format in the blockchain ledger. In the proposed framework, accurate music usage details can be created, details are stored in blocks without changes or omissions, and eventually transparent settlement and distribution are possible by processing smart contract, instead of previous non-transparent settlement practice.
主题音乐、背景音乐、信号音乐是插入广播内容的音乐,与普通音乐一样被认为是创作内容。因为有词作者和作曲家拥有音乐的权利,所以版权费是分配的。然而,由于使用细节的遗漏和结算方式不透明,经常出现主题、背景和信号音乐使用情况监测结果不准确的问题。本文提出了一种基于区块链的音乐使用监控信息生成方法,基于区块链的使用监控工具基于监控机构的特征过滤技术记录音乐源的使用信息。本文提出的框架包括区块链网络结构,存储主题、背景和信号音乐使用历史的一系列交易程序以及区块链分类帐中记录的数据格式。在提议的框架中,可以创建准确的音乐使用细节,详细信息存储在块中而不会更改或遗漏,最终通过处理智能合约实现透明结算和分发,而不是以前的非透明结算实践。

Offline Automatic Speech Recognition System Based on Bidirectional Gated Recurrent Unit (Bi-GRU) with Convolution Neural Network 基于卷积神经网络双向门控循环单元(Bi-GRU)的离线自动语音识别系统

In recent years, the usage of smart phones increased rapidly. Such smartphones can be controlled by natural human speech signals with the help of automatic speech recognition (ASR). Since a smartphone is a small gadget, it has various limitations like computational power, battery, and storage. But the performance of the ASR system can be increased only when it is in online mode since it needs to work from the remote server. The ASR system can also work in offline mode, but the performance and accuracy are less when compared with online ASR. To overcome the issues that occur in the offline ASR system, we proposed a model that combines the bidirectional gated recurrent unit (Bi-GRU) with convolution neural network (CNN). This model contains one layer of CNN and two layers of gated Bi-GRU. CNN has the potential to learn local features. Similarly, Bi-GRU has expertise in handling long-term dependency. The capacity of the proposed model is higher when compared with traditional CNN. The proposed model achieved nearly 5.8% higher accuracy when compared with the previous state-of-the-art methods.
近年来,智能手机的使用迅速增加。这种智能手机可以在自动语音识别(ASR)的帮助下,通过自然的人类语音信号来控制。由于智能手机是一个小工具,它有各种限制,如计算能力,电池和存储。但是ASR系统的性能只有在在线模式下才能提高,因为它需要从远程服务器工作。ASR系统也可以在离线模式下工作,但与在线ASR相比,其性能和精度都有所降低。为了克服离线ASR系统中出现的问题,我们提出了一种将双向门控循环单元(Bi-GRU)与卷积神经网络(CNN)相结合的模型。该模型包含一层CNN和两层门控Bi-GRU。CNN有学习本地特征的潜力。同样,Bi-GRU在处理长期依赖方面也有专长。与传统的CNN相比,该模型的容量更高。与之前的最先进的方法相比,该模型的精度提高了近5.8%。

Although Augmented Reality applications are becoming increasingly popular, the lack of visual realism in rendering still remains an open problem due to its computational cost. Physically-based algorithms can generate renderings with a high degree of photorealism, and they are becoming popular after the recent development of hardware accelerators. This work shows how to integrate Augmented Reality frameworks with ray tracing frameworks to create scenes with high-quality, real-time reflections and refractions, with emphasis on the blending of virtual objects to the real environment. To support the interaction between real and virtual elements, a textured cube using images from the real environment must be provided. Our framework does not add processing overhead to the application when comparing the use of the proposed middleware to the use of ray tracing frameworks alone. We will show that with our approach, photorealistic augmented reality rendering can be achieved in real time without the use of any special equipment.
尽管增强现实应用变得越来越流行,但由于其计算成本,在渲染中缺乏视觉真实感仍然是一个悬而未决的问题。基于物理的算法可以生成具有高度真实感的渲染图,在最近硬件加速器的发展之后,它们变得流行起来。这项工作展示了如何将增强现实框架与光线追踪框架集成在一起,以创建具有高质量,实时反射和折射的场景,重点是将虚拟对象与真实环境混合。为了支持真实元素和虚拟元素之间的交互,必须提供使用来自真实环境的图像的纹理多维数据集。当比较使用提议的中间件和单独使用光线追踪框架时,我们的框架不会给应用程序增加处理开销。我们将展示,通过我们的方法,可以在不使用任何特殊设备的情况下实时实现逼真的增强现实渲染。
