Intelligent Mobile Electrocardiogram Monitor-empowered Personalized Cardiac Big Data* 智能移动心电图监护-个性化心脏大数据*
Jiadao Zou, Qingxue Zhang, Kyle Frick
Smart health big data is quickly driving the healthcare field and bringing numerous new opportunities. Cardiac disease is a leading cause of death worldwide, and the personalized cardiac big data is expected to offer new strategies and possibilities for cardiac health management. The standard 12-lead electrocardiogram (ECG) has been a gold standard of cardiac health measurement for decades. However, there is still lack of effective ways to monitor 12-lead ECG in our daily lives, which is a critical obstacle towards personalized cardiac big data. In this study, we have proposed and validated a mobile 3-lead ECG monitoring system that can reconstruct the standard 12-lead ECG, offering a much greater usability for daily ECG tracking compared with the traditional 12-lead ECG system. Moreover, the system is able to deal with severe motion artifacts during daily physical exercises and yield high-fidelity ECG reconstruction, leveraging a deep recurrent neural network. A multi-stage long short-term memory network has been proposed to reconstruct the robust 12-lead ECG from the noisy 3-lead ECG. This motion artifacts-tolerant ability is highly important, considering that users may perform diverse and random physical activities, which will inevitably contaminate or even corrupt the ECG signal. The reconstruction error is as low as 0.069, and the correlation coefficient is as high as 0.84. This unobtrusive and motion-tolerant mobile ECG monitoring system has been validated on human data and demonstrated the feasibility to continuously establish the personalized cardiac big data. This research is highly encouraging and is expected to be able to significantly advance big data-driven cardiac health management.
智能健康大数据正在快速推动医疗领域的发展,并带来无数新的机遇。心脏疾病是世界范围内的主要死亡原因,个性化心脏大数据有望为心脏健康管理提供新的策略和可能性。几十年来,标准的12导联心电图(ECG)一直是心脏健康测量的黄金标准。然而,在我们的日常生活中仍然缺乏有效的12导联心电图监测方法,这是实现个性化心脏大数据的关键障碍。在这项研究中,我们提出并验证了一种移动3导联心电监测系统,该系统可以重建标准的12导联心电,与传统的12导联心电系统相比,在日常心电跟踪中提供了更大的可用性。此外,该系统能够处理日常体育锻炼中的严重运动伪影,并利用深度递归神经网络产生高保真的心电图重建。提出了一种多阶段长短期记忆网络,从噪声的3导联心电重构出鲁棒的12导联心电。考虑到用户可能进行各种随机的身体活动,这些活动不可避免地会污染甚至破坏心电信号,这种容忍运动伪影的能力非常重要。重建误差低至0.069,相关系数高达0.84。这种不显眼、运动耐受的移动心电监测系统已经在人体数据上进行了验证,证明了持续建立个性化心脏大数据的可行性。这项研究非常鼓舞人心,有望显著推进大数据驱动的心脏健康管理。

Iterative MPC for Energy Management and Load Balancing in 5G Heterogeneous Networks 基于迭代MPC的5G异构网络能量管理与负载均衡
A. Ornatelli, A. Tortorelli, A. Giuseppi
Multi-Access Heterogeneous Networks introduced a step forward in modern communication networks allowing the provision of reliable and efficient broadband services. However, heterogeneous networks imply a burden of complexity in the integration, coordination and QoS management processes thus complicating the satisfaction of users’ requirements. The aim of the present work is to address the above-mentioned issues by developing a mathematical framework for optimizing resource usage in 5G heterogeneous networks. More in detail, the optimization will take into account both the network’s load and energy consumption simultaneously. The proposed approach, based on Model Predictive Control, will be compared with other control strategies for validation and performance comparison.

Performance Evaluation for Tracking a Malicious UAV using an Autonomous UAV Swarm 基于自主无人机群的恶意无人机跟踪性能评估
C. Arnold, Jason Brown
Recent instances of malicious Unmanned Aerial Vehicles (UAVs) causing service disruption or damage to critical infrastructure has prompted research into methods of mitigating and deterring such nefarious activities. One such countermeasure is to use a swarm of UAVs to track the malicious UAV back to its origin. In this paper, we evaluate different methods of swarm formation for the purposes of malicious UAV tracking via a bespoke OMNeT++ simulation. The simulation also evaluates the effect of the number of UAVs in the swarm, as well as the evasiveness of the malicious UAV in terms of its flight capabilities and flight path. The results demonstrate that encirclement type swarm formations such as Surround and Cone, in which the malicious UAV is surrounded by the swarm, perform better than a follow type swarm formation in their ability to continue to track the malicious UAV.
最近恶意无人机(uav)造成服务中断或关键基础设施损坏的实例促使人们研究减轻和阻止此类恶意活动的方法。一个这样的对策是使用一群无人机跟踪恶意无人机回到它的原点。在本文中,我们通过定制的omnet++仿真评估了用于恶意无人机跟踪的不同蜂群形成方法。仿真还评估了蜂群中无人机数量的影响,以及恶意无人机在飞行能力和飞行路径方面的闪避性。结果表明,围城型(Surround)和锥型(Cone)蜂群编队中,恶意无人机被蜂群包围,其持续跟踪能力优于跟随型(follow)蜂群编队。

An Autonomous Delivery Robot to Prevent the Spread of Coronavirus in Product Delivery System 防止冠状病毒在产品配送系统中传播的自主配送机器人
Murad Mehrab Abrar, Raian Islam, Md. Azad Hossen Shanto
Due to the coronavirus situation around the world, safe and contactless home delivery services have become substantial concerns for the people while they are forced to stay at home. In this context, we have proposed a prototype robot that can be very helpful to reduce the risk of infectious disease transmission in the product delivery system during the extreme strain on healthcare and hygiene. The design and development of a cost effective autonomous mobile robot prototype have been presented that can deliver packages safely to a desired destination using Global Positioning System (GPS). The robot ensures a secure and human-contactless delivery by using a password protected container to carry the delivery package. The four wheel drive robot can successfully navigate to a preset location by receiving GPS coordinates from satellites and correcting its direction using a digital compass. After the robot arrives at its destination, it waits for the customer to unlock the container. The customer will have to use a password upon delivery to unlock the container and retrieve the ordered product. This password can be sent to the customer with the order confirmation message. After completing the delivery, the robot can autonomously return to its starting location. Heading angle accuracy test and trajectory completion accuracy test have been performed to ascertain the accuracy of the robot. Alongside an infection risk-free product delivery, our robot can be an effective technological solution of the last mile problem which will reduce the last mile delivery cost significantly.
由于全球范围内的冠状病毒疫情,安全和非接触式送货上门服务已成为人们在被迫呆在家里时的主要关注点。在这种情况下,我们提出了一个原型机器人,它可以在医疗保健和卫生极度紧张的情况下,非常有助于降低产品输送系统中传染病传播的风险。提出了一种具有成本效益的自主移动机器人原型的设计和开发,该机器人可以使用全球定位系统(GPS)将包裹安全地运送到期望的目的地。机器人通过使用密码保护的容器来携带包裹,确保安全且无人类接触的递送。这个四轮驱动的机器人可以通过接收卫星的GPS坐标,并使用数字指南针校正方向,成功地导航到预设的位置。机器人到达目的地后,等待顾客解锁集装箱。客户必须在交付时使用密码来解锁容器并检索订购的产品。此密码可以与订单确认消息一起发送给客户。完成配送后,机器人可以自动返回到起始位置。为了确定机器人的精度,进行了航向角精度试验和轨迹完成精度试验。除了无感染风险的产品交付,我们的机器人可以成为最后一英里问题的有效技术解决方案,这将大大降低最后一英里的交付成本。

Healthcare Security Based on Blockchain within Multi-parameter Chaotic Map 基于多参数混沌映射的区块链医疗安全研究
A. Drebee, A. Topcu, Yasamin Alagrash
Healthcare-related costs still pose problems despite the availability of large quantities of healthcare information. In this paper we propose reducing health-related costs while not violating the privacy of information related to the patients, and we also address the authentication of the blockchain. This study makes use of raw data by processing it in a reasonable way to provide effective and less costly healthcare services along with the needed privacy and ease of accessibility of information to the relevant providers. The current paper utilizes the properties of the logistic map as SHA-256 calculates the hash value for the plain text, with the results being applied to change the initial keys for the logistic map. For expansion of the chaotic region of the logistic map and for making it better suited for the generation key, a mixture of multiple parameters of the logistic map key generation is proposed. Algorithm 2 shows how to generate a new key for the hash function for the new block. A key generator based on logistic map theory can be applied. The key generator is not meant to regenerate, which means that it is not possible to regenerate the same key. Therefore, the authentication is strengthened.
尽管有大量的医疗保健信息,但与医疗保健相关的费用仍然构成问题。在本文中,我们建议在不侵犯患者相关信息隐私的情况下降低与健康相关的成本,并解决区块链的身份验证问题。本研究利用原始数据,以合理的方式对其进行处理,以提供有效且成本较低的医疗保健服务,同时提供所需的隐私和相关提供商易于访问的信息。本文利用逻辑映射的属性作为SHA-256计算纯文本的哈希值,并将结果应用于更改逻辑映射的初始键。为了扩大逻辑映射的混沌区域并使其更适合生成密钥,提出了一种多参数混合的逻辑映射密钥生成方法。算法2展示了如何为新块的哈希函数生成一个新密钥。可以采用基于逻辑映射理论的密钥生成器。密钥生成器不打算重新生成,这意味着不可能重新生成相同的密钥。因此,加强了认证。

On Efficient Candidate Path Selection for Dynamic Routing in Elastic Optical Networks 弹性光网络中动态路由的有效候选路径选择
Bijal Patel, Haiyang Ji, S. Nayak, Ting Ding, Yue Pan, Michal Aibin
Elastic Optical Networks are based on the Orthogonal frequency-division multiplexing (OFDM), thus providing a more efficient and flexible data-transferring network than fixed-grid WDM networks. In this paper we solve the Routing, Modulation and Spectrum Assignment (RMSA) problem. For this purpose, we design a new, highly efficient Adaptive Dynamic Routing Algorithm (ADRA). Our results show that it outperforms other methods from the literature.

Yash Parikh, Eman Abdelfattah
This paper investigates how clustering algorithms and Recency, Frequency, and Monetary value (RFM) analysis can be performed on online transactions to provide strategies for customer purchasing behaviors. Along with performing RFM analysis on the retail dataset, clustering algorithms such as Mean-shift, Density-Based Spatial Clustering of Applications with Noise (DBSCAN), Agglomerative Clustering, and K-Means were utilized. By comparing these clustering algorithms, we have found valuable customer groups based on RFM values.

Deep Convolutional Neural Network for Decoding EMG for Human Computer Interaction 面向人机交互的深度卷积神经网络肌电信号解码
Qi Wang, Xianping Wang
sEMG is a promising human computer interaction approach, which has been widely used in myriads of areas. To perform sEMG classification, more and more sophisticated machine learning strategies have been developed. However, the deep neural network still has limited applications on sEMG decoding, though it has got a great success in the computer vision area. In this study, we propose a new deep learning framework to classify hand gestures based on sEMG, especially we perform convolutional neural network (CNN) on multiple-session sEMG, which is more challenging because of the time-varying biodynamics of the subjects. So we also investigate the topologies of CNN, expecting to get an optimized architecture to effectively detect the hidden features in the signals. It is shown that the proposed CNN framework in this study has a high classification accuracy for sEMG-based hand gesture recognition, and the difference of topologies has great impact on the performance of CNN. This study lays a promising foundation for multiple-session sEMG signal pattern recognition by CNN.
表面肌电信号是一种很有前途的人机交互方法,已广泛应用于许多领域。为了进行表面肌电信号分类,越来越多复杂的机器学习策略被开发出来。然而,尽管深度神经网络在计算机视觉领域取得了巨大的成功,但它在表面肌电信号解码方面的应用仍然有限。在这项研究中,我们提出了一种新的基于表面肌电信号的深度学习框架来对手势进行分类,特别是我们在多会话表面肌电信号上执行卷积神经网络(CNN),由于受试者的生物动力学时变,这更具挑战性。因此,我们还研究了CNN的拓扑结构,期望得到一个优化的架构,以有效地检测信号中的隐藏特征。研究表明,本文提出的CNN框架对于基于表面肌电信号的手势识别具有较高的分类准确率,而拓扑结构的差异对CNN的性能影响较大。本研究为CNN的多会话表面肌电信号模式识别奠定了良好的基础。
