Flexible electronics are envisioned to play a major role in future wearable medical devices. An important component of this technology is flexible antennas. This paper presents a preliminary study of on-body and off-body propagation channels in Body Area Networks (BAN) using a small Ultra WideBand (UWB) flexible wearable antenna. The research is carried out with physical measurements in an anechoic chamber and a small laboratory room. The on-body measurements include propagation channels between two wearable devices placed on the head and various locations on the arm (i.e., shoulder to wrist). The off-body measurements cover propagation channels between a head-mounted device and an external device placed at various distances from the body. The wearable devices in these measurements use a small flexible antenna that can easily conform to the surface of the body. The measurements are conducted to better understand and characterize the wireless communication channels in applications such as brain monitoring or brain computer interface. The measurement results show that the UWB flexible antenna presented here performs well for both on-body and off-body communication channels.

Estimation of Source Direction with Spherical Array Receiver in Molecular Communication 分子通信中球形阵列接收机的源方向估计
Fardad Vakilipoor, Abdulhamid N. M. Ansari, M. Ferrari, Maurizio Magarini
This paper proposes a method to estimate the direction of a point source in a diffusive molecular communication (MC) system. The estimator neither requires the knowledge of the number of released molecules nor the distance from the source. The goal is achieved via a specifically designed spherical array of receivers composed of a finite number of fully-absorbing (FA) elements, i.e. receivers. It is proved that the source direction estimation without the knowledge of the number of released molecules is feasible only for the symmetrical configuration of receivers on the array. The proposed approach is based on a model for the temporal asymptotic number of molecules absorbed by multiple FA receivers that takes into account their reciprocal interaction. The accuracy of the estimation is measured in terms of root mean squared error for different scenarios.
提出了一种在扩散分子通信系统中估计点源方向的方法。估计器既不需要知道释放分子的数目,也不需要知道到源的距离。该目标是通过一个专门设计的球形接收器阵列来实现的,该阵列由有限数量的全吸收(FA)元件组成,即接收器。证明了不知道释放分子数的源方向估计只有在阵列上接收器对称配置时才可行。提出的方法是基于多个FA接收器吸收的时间渐近分子数的模型,该模型考虑了它们的相互作用。估计的准确性是根据不同情况下的均方根误差来衡量的。

Real-Time Mastitis Detection in Livestock using Deep Learning and Machine Learning Leveraging Edge Devices 利用边缘设备进行深度学习和机器学习的牲畜乳腺炎实时检测
Kawshik Kumar Ghosh, Md. Fahim Ul Islam, Abrar Ahsan Efaz, Amitabha Chakrabarty, Shahriar Hossain
Livestock production is a crucial part of the global economy with a worth of estimated $1.4 trillion. It provides livelihoods for 1.3 billion people and supports 600 million poor rural household farmers in developing countries. In Bangladesh, it contributes 6.5% to the country's GDP. However, this industry faces substantial financial setbacks when contagious diseases transmit among their livestock. One of the most common and expensive diseases affecting the livestock industry is Bovine Mastitis. This paper presents a real-time system for detecting bovine mastitis in livestock using deep learning (dl) and machine learning (ml) techniques. The system aims to provide a timely and accurate diagnosis of mastitis, ultimately reducing costs and improving the efficiency of treatment. By utilizing dl and ml techniques, the system is able to analyze data collected from edge devices and make accurate predictions about the presence of mastitis. The dataset that has been used for the classification contains both an Image dataset consisting of 1341 images and a Numerical dataset that had been taken from 1100 cows over a period of six days. The edge device utilizes sensors and cameras to collect data from the cow, which is then processed through ml and dl algorithms using Raspberry Pi and cloud computing respectively, and then displays if the cow is infected with mastitis or not. Inception V3 and RandomForest algorithms were used for dl and ml, respectively, and had an accuracy of 99.34% and 99% respectively. The proposed system has the potential to significantly reduce the economic impact of this disease in the dairy industry of Bangladesh and other developing countries by providing timely and accurate diagnosis and helping to improve treatment efficiency and protect the health and productivity of livestock animals.
畜牧业生产是全球经济的重要组成部分,价值约为1.4万亿美元。它为发展中国家13亿人提供生计,并支持6亿贫困农村家庭农民。在孟加拉国,它为该国的GDP贡献了6.5%。然而,当传染病在他们的牲畜中传播时,这个行业面临着严重的财政挫折。影响畜牧业的最常见和最昂贵的疾病之一是牛乳腺炎。本文提出了一种利用深度学习(dl)和机器学习(ml)技术检测牲畜牛乳腺炎的实时系统。该系统旨在为乳腺炎提供及时准确的诊断,最终降低成本,提高治疗效率。通过利用深度学习和机器学习技术,该系统能够分析从边缘设备收集的数据,并对乳腺炎的存在做出准确的预测。用于分类的数据集包含一个由1341张图像组成的图像数据集和一个在6天内从1100头奶牛身上采集的数值数据集。边缘设备利用传感器和摄像头收集奶牛的数据,然后分别通过树莓派和云计算的ml和dl算法进行处理,然后显示奶牛是否感染了乳腺炎。dl和ml分别使用Inception V3和RandomForest算法,准确率分别为99.34%和99%。拟议的系统有可能通过提供及时和准确的诊断并帮助提高治疗效率和保护牲畜的健康和生产力,大大减少这种疾病对孟加拉国和其他发展中国家乳制品业的经济影响。

Analysis of Received Power via RIS in Near Field LOS Channels 近场LOS信道中RIS接收功率分析
J. Kokkoniemi
The reconfigurable intelligent surfaces (RISs) are expected to be a cheap way to extend service areas of base stations. This is especially promising in the millimeter wave and THz bands (from 30 GHz to +300 GHz) where base station coverage is expected to be modest and suffer greatly from blockages. As the RISs can potentially be large (physically and via number of sub-elements), there is a good change that a user is in the near field of the RIS. This paper considers RIS near field propagation and achievable power levels close to these surfaces. Ideal energy levels are looked into among with the impact of beamforming and beam squinting. Human safety issues close to these surfaces are also analyzed from the energy density point of view. It is shown that the achievable received power in the near field are very good, but the beam squinting may have a significant impact on the received power and frequency response. We also conclude that RISs are safe for humans even at close proximity due to relatively large channel losses in the reflected channels and hence low power densities in the air.
可重构智能表面(RISs)有望成为扩展基站服务区域的一种廉价方法。这在毫米波和太赫兹频段(从30 GHz到+300 GHz)尤其有希望,因为这些频段的基站覆盖范围预计不大,而且容易受到阻塞的影响。由于RIS可能很大(物理上和通过子元素的数量),因此有一个很好的变化,即用户处于RIS的近场。本文考虑了RIS近场传播和接近这些表面的可实现功率水平。研究了光束形成和光束斜视对理想能级的影响。从能量密度的角度分析了靠近这些表面的人类安全问题。结果表明,近场可实现的接收功率很好,但光束斜视会对接收功率和频率响应产生较大影响。我们还得出结论,由于反射信道中相对较大的信道损失,因此空气中的功率密度较低,因此即使在近距离处,RISs对人类也是安全的。

S. Caputo, Giacomo Borghini, S. Jayousi, Adnan Rashid Chaudhry, L. Mucchi
Visible Light Communication (VLC) technology is proposed as a promising solution that uses light-emitting diodes (LEDs) to transmit data and illumination in the visible portion of the electromagnetic spectrum. VLC offers a large unlicensed bandwidth, high-speed wireless communication, and can also be used for localization purposes. VLC technology, combined with RF communication, could help achieve the sixth generation (6G) of mobile communication targets in terms of low power consumption, high data rate, high reliability, massive user connectivity, low latency, and high security. While VLC technology has been explored in various fields such as high-speed internet connection, autonomous driving, and positioning systems, its potential use in healthcare applications remains relatively unexplored. The paper aims to provide an overview of the current state of research on VLC in healthcare and highlights its promising potential.

Reinforcement Learning based Cloud and Edge Resource Allocation for Real-Time Telemedicine 基于强化学习的实时远程医疗云和边缘资源分配
Ivana Kovacevic, Rana Inzimam Ul Haq, Jude Okwuibe, T. Kumar, S. Glisic, M. Ylianttila, E. Harjula
Future healthcare services will extensively exploit wireless telehealth solutions in various healthcare use cases from preventive home monitoring to highly demanding real-time scenarios, such as monitoring an emergency patient's vital functions in an ambulance or ICU unit. Reliable real-time communications and computing are needed to enable these highly critical health services. However, the majority of current telehealth use cases are cloud - based, which poses a challenge to provide sufficient Quality of Service (QoS). The traditional centralized cloud infrastructure cannot meet the latency and reliability requirements due to long and unreliable communication routes. Therefore, the most advanced cloud solutions integrate edge computing as an integral part of the computational architecture to bring a part of the computational infrastructure to the proximity of the data sources and end-nodes, thus constituting an edge-cloud continuum. This continuum is capable of serving applications with real-time requirements. However, since edge computing capacity is a limited resource, solutions are needed for deciding which tasks should be run on edge and which at the data center. In this paper, we propose a machine learning-based solution to prioritize ultra-low-latency tasks for running on the edge to meet their strict delay requirements while leaving other tasks to be executed at remote servers. Our proposed solution in comparison to the baseline has a significantly lower dropping rate and outperforms fixed - interval scheduling solutions in terms of resource efficiency.
未来的医疗保健服务将在各种医疗保健用例中广泛利用无线远程医疗解决方案,从预防性家庭监控到高要求的实时场景,例如在救护车或ICU病房中监控急诊患者的重要功能。需要可靠的实时通信和计算来实现这些非常关键的保健服务。然而,目前大多数远程医疗用例都是基于云的,这对提供足够的服务质量(QoS)提出了挑战。传统的集中式云基础设施由于通信路由长且不可靠,无法满足时延和可靠性要求。因此,最先进的云解决方案将边缘计算作为计算架构的一个组成部分,将部分计算基础设施带到数据源和终端节点附近,从而构成边缘云连续体。这个连续体能够为具有实时需求的应用程序提供服务。然而,由于边缘计算能力是一种有限的资源,因此需要解决方案来决定哪些任务应该在边缘上运行,哪些任务应该在数据中心运行。在本文中,我们提出了一种基于机器学习的解决方案,以优先考虑在边缘运行的超低延迟任务,以满足其严格的延迟要求,同时将其他任务留在远程服务器上执行。与基线相比,我们提出的解决方案具有显着降低的掉落率,并且在资源效率方面优于固定间隔调度解决方案。

Our proposed solution in comparison to the baseline has a significantly lower dropping rate and outperforms fixed - interval scheduling solutions in terms of resource efficiency.","PeriodicalId":332729,"journal":{"name":"2023 IEEE 17th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131250300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

N. Alsbou, Reuben Lane, Lalita Gurung, Imad Ali
Internet of Things (IoT)-enabled networks have utilized progress in wireless sensor technologies to bring greater connectivity to homes, streets, cars, offices, industries, college campuses, and even entire cities. One area which would greatly benefit from this is the biology laboratory setting, where constant and careful monitoring of samples is often required. This work proposes the implementation of a smart biology lab to assist with the maintenance of cell cultures and the production of accurate and reliable research. Cisco Packet Tracer, a network simulation tool, simulates the firewall-secured laboratory network with embedded IoT functions of environmental data sensing and storage, motion-activated lighting, and cell culture monitoring through a smart incubator. A hardware implementation of the system was developed and tested with the additional functionality of push notifications to alert users of abnormal data readings.

Medical Imaging System Design using Microwave Antennas and Portable Platform 基于微波天线和便携式平台的医学成像系统设计
N. Alsbou, Karidjatou Cisse, Colton Cox, Mubaraak Akinbola, Imad Ali
When discussing medical imaging systems, microwave imaging is considered one of the emerging techniques that provide fast, safe, cost effective and noninvasive medical imaging modality compared to other conventional imaging techniques such as x-ray, magnetic resonance imaging (MRI), and computed tomography imaging (CT). The imaging in microwave imaging system can be performed by mapping the interactions of microwave photons with the medium including signal reflection, attenuation and propagation. These factors are dependent on the water or blood content of the tissue. The maps of electromagnetic properties of the tissue generated with microwave imaging is used to generate medical images for different clinical applications such as leukemia, bone degradation, tumor and traumatic brain injury (TBI) detection. This paper proposes a medical imaging system that is able to produce three-dimensional images in a much safer and cheaper way compared to conventional imaging methods. The medical imaging system proposed is a work in progress and this paper is intended to outline the design and show the preliminary medical images obtained.
在讨论医学成像系统时,与其他传统成像技术(如x射线、磁共振成像(MRI)和计算机断层扫描成像(CT))相比,微波成像被认为是提供快速、安全、经济有效和无创医学成像方式的新兴技术之一。微波成像系统中的成像可以通过映射微波光子与介质的相互作用来完成,包括信号的反射、衰减和传播。这些因素取决于组织中的水或血液含量。微波成像生成的组织电磁特性图用于生成不同临床应用的医学图像,如白血病、骨降解、肿瘤和创伤性脑损伤(TBI)检测。本文提出了一种医学成像系统,它能够以一种比传统成像方法更安全、更便宜的方式产生三维图像。提出的医学成像系统是一个正在进行的工作,本文旨在概述设计并展示初步获得的医学图像。
