C. Anisha, N. Arulanand
Parkinson Disorder (PD) is a neurological disorder which is progressive and degenerative in nature. There are no specific tests pertaining to the diagnosis of PD. The symptoms at an early stage are mild. The early diagnosis of PD is really essential to delay the progression of the disorder. Speech disorder namely dysphonia is experienced by approximately 90% of PD patients. The incorporation of Artificial Intelligence (AI) techniques integrated with non-invasive capture of speech data from patients in diagnosis system aids to provide a robust, reliable and accurate estimation of Unified Parkinson Disease Rating Scale (UPDRS) score which ease the decision-making process effective for healthcare professionals. The proposed system incorporates a novel tuned Homogenous Ensemble Regressor wherein the hyperparameters are chosen and tuned using various experiments. Tuned Extreme Gradient (XgBoost) Regressor and Tuned Random Forest (RF) Regressor are the two homogenous regressor model. The proposed system is compared with the Tuned Linear Regression (LR) model which is the single Regressor model. The proposed system is evaluated using the large database of voice features samples of 42 PD patients. The Mean Absolute Error (MAE) and Mean Squared Error (MAE) values are minimal for the proposed system and it shows that the errors of the proposed system are lower than the single classifier errors and existing similar system.
帕金森病(PD)是一种进行性和退行性神经系统疾病。没有与帕金森病诊断相关的特殊检查。早期症状很轻微。PD的早期诊断对于延缓疾病的发展至关重要。大约90%的PD患者都有语言障碍,即语音障碍。人工智能(AI)技术与诊断系统中患者语音数据的非侵入性捕获相结合,有助于提供统一帕金森病评定量表(UPDRS)评分的稳健、可靠和准确估计,从而简化医疗保健专业人员有效的决策过程。所提出的系统采用了一种新的调谐同质集成回归器,其中超参数是通过各种实验选择和调谐的。调谐极端梯度(XgBoost)回归量和调谐随机森林(RF)回归量是两种同质回归模型。将该系统与调谐线性回归(LR)模型(单回归模型)进行了比较。利用42例PD患者的语音特征样本的大型数据库对所提出的系统进行了评估。所提系统的平均绝对误差(MAE)和均方误差(MAE)值最小,表明所提系统的误差低于单一分类器的误差和现有的类似系统。

Dakhole Dipali
Agriculture is the main livelihood in India. Most of the people earn bread and butter through farming, but the farmers are not getting enough profit and the field is facing growth downward due to irregular rainfall, high volatility in agriculture commodity prices and uncertainties in production. The objective of this study is to design and implement an automated crop price prediction system with best suitable machine learning technique, as well as displaying prediction results on website Krishi-Stats designed for easy understanding for Farmers. In this study, three machine-learning (ML) algorithms, ARIMA, VAR and XGBoost are applied on large historical data collected from government website. The ML algorithms compared with their root mean square error values (RMSE). As XGBoost has given optimum RMSE value of 0.94, has been selected as the prediction system engine of our website Krishi-Stats. On website, the crop prediction prices are plotted for all twelve selected crops and visualized using prediction graphs.
农业是印度的主要生计。大多数人通过农业赚取面包和黄油,但农民没有获得足够的利润,而且由于降雨不规律、农产品价格高度波动和生产不确定,该领域面临增长下降。本研究的目的是设计和实现一个采用最合适的机器学习技术的自动农作物价格预测系统,并在Krishi-Stats网站上显示预测结果,以方便农民理解。本研究将ARIMA、VAR和XGBoost三种机器学习算法应用于政府网站收集的大量历史数据。将ML算法与它们的均方根误差值(RMSE)进行比较。由于XGBoost给出的最优RMSE值为0.94,我们选择XGBoost作为Krishi-Stats网站的预测系统引擎。在网站上,作物预测价格是为所有12种选定作物绘制的,并使用预测图进行可视化。

Deep Learning based DFWF Model for Audio Spoofing Attack Detection 基于深度学习的音频欺骗攻击检测DFWF模型
Kottilingam Kottursamy
One of the biggest threats in the speaker verification system is that of fake audio attacks. Over the years several detection approaches have been introduced that were designed to provide efficient and spoof-proof data-specific scenarios. However, the speaker verification system is still exposed to fake audio threats. Hence to address this issue, several authors have proposed methodologies to retrain and finetune the input data. The drawback with retraining and fine-tuning is that retraining requires high computation resources and time while fine-tuning results in degradation of performance. Moreover, in certain situations, the previous data becomes unavailable and cannot be accessed immediately. In this paper, we have proposed a solution that detects fake without continual-learning based methods and fake detection without forgetting in order to develop a new model which is capable of detecting spoofing attacks in an incremental fashion. In order to retain original model memory, knowledge distillation loss is introduced. In several scenarios, the distribution of genuine voice is said to be very consistent. In several scenarios, there is consistency in distribution of genuine voice hence a similarity loss is embedded additionally to perform a positive sample alignment. The output of the proposed work indicates an error rate reduction of up to 80% as observed and recorded.
扬声器验证系统中最大的威胁之一是假音频攻击。多年来,已经引入了几种检测方法,旨在提供有效且防欺骗的特定数据场景。然而,扬声器验证系统仍然暴露在虚假音频威胁中。因此,为了解决这个问题,一些作者提出了重新训练和微调输入数据的方法。再训练和微调的缺点是再训练需要大量的计算资源和时间,而微调会导致性能下降。此外,在某些情况下,以前的数据变得不可用,不能立即访问。在本文中,我们提出了一种不基于持续学习的方法检测虚假和不遗忘虚假检测的解决方案,以开发一种能够以增量方式检测欺骗攻击的新模型。为了保留原有的模型记忆,引入了知识蒸馏损失。在一些场景中,真实声音的分布据说是非常一致的。在一些情况下,真实语音的分布存在一致性,因此额外嵌入相似性损失以执行正样本比对。所建议工作的输出表明,观察和记录的错误率降低了80%。

Radial Differentiation of Pump and Signal Intensities in Trapezoidal index EDFA for LP11 mode in Kerr nonlinear state Kerr非线性状态下LP11模式梯形指数EDFA的泵浦径向分化和信号强度
Biplob Kumar Ray, Angshuman Majumdar, S. Gangopadhyay
An Erbium-Doped Fiber Amplifier (EDFA) is an in-line component in modern all –optical telecommunication infrastructure. Different parametric characteristics of an EDFA express the suitability and excellency of performance in its real field application. Intensities of pump and signal vary with distance from the core-axis along the radius of the fiber which is one of the significant characteristics of an EDFA. Change of behavior of pump and signal intensities along the radius of the fiber in an erbium-doped dual-mode trapezoidal index fiber made amplifier due to Kerr nonlinearity phenomenon originating from launching and transmission of intense light from LASER beam inside the amplifier for the LP_11 mode has been exercised in this case. In the present case, some trapezoidal-index fibers of different normalised frequencies have been opted. This exercise is an implementation of the reliable and easy mathematical instrument, the Chebyshev technique. Results derived in this exercise exhibit a fantastic similarity with those derived by the rigorous finite element method. This study with implementation of such a reliable and easy technique may help the interested optical engineers.

Automatic Temperature Detection and Sanitization with Authorized Entry using Face Mask Detection 自动温度检测和消毒与授权进入使用口罩检测
Rukia Rahman
To contain the chain of Covid-19, taking on the role of Engineering Ambassador of humanity in these dire conditions, this paper develops an electronic equipment referred holistically as “Covid Tunnel” or “Disinfectant Tunnel”. The general thesis from which the whole work has evolved is to make use of temperature control and automation by programming to try to pin the potential host of virus in possible hotspots viz., hospitals, administrative complexes, strategic junctions, etc. The first and foremost import of this benevolent project is the application of Automatic Temperature Control. Arduino Nano Temperature Control is employed for checking the temperature of each entrant at the entrance gate. For instance, if a person entering happens to have a body temperature above 38C, the buzzer goes on indicating a red flag for the entry. The second and equally important process is filtering based on the face mask. Now, a webcam attached right after, which is program-based on Python, Open CV, Tensor Flow etc. provides the necessary input and the program searches for the face mask. If the entrant is unmasked, a voice in Urdu commands for wearing of the face mask. While a masked person enters, the automated sanitizer pops out for sanitizing as a precautionary measure. The sanitizer itself is automated by a DC motor which in turn is driven by MOSFET integrated circuit. Thusly, this paper tries to kick in with the Electronics and Information Technology and helps arrest the spread of the virus in the community, anticipating a Coronavirus-free world.
为了遏制Covid-19链,在这些恶劣条件下承担人类工程大使的角色,本文开发了一种电子设备,统称为“Covid隧道”或“消毒剂隧道”。整个工作发展的一般论点是利用温度控制和自动化编程,试图将病毒的潜在宿主锁定在可能的热点地区,即医院,行政综合体,战略枢纽等。这个慈善项目的第一个也是最重要的是自动温度控制的应用。使用Arduino纳米温度控制器在入口处检查每个进入者的温度。例如,如果一个人进入时体温高于38度,蜂鸣器就会发出红色信号。第二个也是同样重要的过程是基于口罩的过滤。现在,一个基于Python, Open CV, Tensor Flow等程序的网络摄像头提供了必要的输入,程序搜索口罩。如果参赛者没有戴口罩,就会有一个乌尔都语的声音命令他戴上口罩。当戴面具的人进入时,自动消毒机就会跳出来消毒,作为预防措施。消毒机本身由直流电机自动化,直流电机由MOSFET集成电路驱动。因此,本文试图与电子和信息技术相结合,帮助遏制病毒在社区中的传播,期待一个没有冠状病毒的世界。

5G Coverage Planning for Urban Area at Kathmandu City, Nepal 尼泊尔加德满都城区5G覆盖规划
Nirmala Sharma, S. Shakya
The excitement about the 5G wireless network has passed. Mobile network operators (MNO) have begun rolling out 5G networks alongside 4G cellular networks in lower frequency and mid-frequency bands (i.e., 3-6 GHz) all over the world. The mid-frequency band can greatly improve the performance of the current network (i.e., 50 MHz–100 MHz). All we know that the wider spectrum can be provided by the high frequency bands which is required to fulfill the greatest bitrates (20 Gb/s), lowest latencies, and constantly increasing capacity demands. The free space propagation loss rapidly increases as we move to higher frequency bands, that will reduce the individual cell site radius to 100 m for the high frequency band from various distances in 4G. To offer consistent 5G coverage, the MNOs will have significant challenges in precisely planning and acquiring these enormous numbers of new cell site locations. This paper describes about the signal characteristics at 800MHz, 1800MHz for 4G and at 700MHz, 2300MHz, 2600MHz, 3500MHz for 5G and the upgradation of 4G towards 5G in the test environment. The 5G Coverage Planning with three sector cells and its SINR Mapping in advance antenna array will be performed to provide better coverage in 5G environments.
对5G无线网络的兴奋已经过去了。移动网络运营商(MNO)已经开始在全球范围内推出5G网络和4G蜂窝网络,覆盖低频和中频频段(即3-6 GHz)。中频频段可以大大提高当前网络的性能(即50 MHz - 100 MHz)。我们都知道,更宽的频谱可以由高频段提供,这需要满足最大的比特率(20 Gb/s),最低的延迟和不断增加的容量需求。随着我们移动到更高的频段,自由空间传播损失迅速增加,这将使4G中各个距离的单个小区站点半径在高频段减少到100米。为了提供一致的5G覆盖,移动网络运营商在精确规划和获取这些庞大的新蜂窝基站位置方面将面临重大挑战。本文介绍了4G在800MHz、1800MHz和5G在700MHz、2300MHz、2600MHz、3500MHz的信号特性,以及在测试环境下4G向5G的升级。为了在5G环境下提供更好的覆盖,将进行三扇区小区的5G覆盖规划和提前天线阵列的信噪比映射。

Design of a Customized Intelligent Electronic Device for Power Circuit Safety 一种电力电路安全定制智能电子装置的设计
P. Ebby Darney
The Intelligent Electronic Devices (IEDs) are widely used to control the power circuits through an automated control device. The main motive of IEDs is to monitor the power flow, enable the control process and meter the changes. In some cases, the IEDs are employed as an electronic circuit breaker for providing a reliable operation. It is achieved by operating the relays through digital signals. The traditional methods have been using a mechanical system for operating the circuit breakers, which requires a manual operation for resting the breakers. The modern IEDs are developed to reset the operation by its own but such systems are heavily affected through data intrusions. Therefore, a programmed IED is developed in the proposed work to analyze if the decisions made by the IEDs are original or fake in a simulated observation. It is done with a mathematical averaging algorithm with respect to time for estimating a threshold. The experimental outcome indicates that the performance of the customized IED is better over the traditional IEDs. Moreover, the proposed device saves the energy distribution in a power system by avoiding the fake operations created in the IEDs through external intrusions.
智能电子器件(Intelligent Electronic Devices,简称ied)是一种通过自动化控制装置对电力电路进行控制的器件。ied的主要目的是监测潮流,实现控制过程并测量变化。在某些情况下,简易爆炸装置被用作电子断路器,以提供可靠的操作。它是通过数字信号操作继电器来实现的。传统的方法一直是使用机械系统来操作断路器,这需要人工操作来休息断路器。现代的简易爆炸装置是为了自己重置操作而开发的,但这样的系统会受到数据入侵的严重影响。因此,在建议的工作中开发了一个程序化的IED,以分析IED在模拟观测中做出的决定是原始的还是虚假的。它是用一个数学平均算法关于时间来估计阈值。实验结果表明,该装置的性能优于传统的简易爆炸装置。此外,该装置通过避免外部入侵在简易爆炸装置中产生的虚假操作,节省了电力系统中的能量分配。

The main motive of IEDs is to monitor the power flow, enable the control process and meter the changes. In some cases, the IEDs are employed as an electronic circuit breaker for providing a reliable operation. It is achieved by operating the relays through digital signals. The traditional methods have been using a mechanical system for operating the circuit breakers, which requires a manual operation for resting the breakers. The modern IEDs are developed to reset the operation by its own but such systems are heavily affected through data intrusions. Therefore, a programmed IED is developed in the proposed work to analyze if the decisions made by the IEDs are original or fake in a simulated observation. It is done with a mathematical averaging algorithm with respect to time for estimating a threshold. The experimental outcome indicates that the performance of the customized IED is better over the traditional IEDs. Moreover, the proposed device saves the energy distribution in a power system by avoiding the fake operations created in the IEDs through external intrusions.","PeriodicalId":74231,"journal":{"name":"Multiscale multimodal medical imaging : Third International Workshop, MMMI 2022, held in conjunction with MICCAI 2022, Singapore, September 22, 2022, proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81913813","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}

Future Trends for Carbon Nanotube Transistors in Sensing and Transmitting Data 碳纳米管晶体管在传感和传输数据方面的未来趋势
G. Rajakumar
Recently, the printing technologies for mass producing flexible and elastic electronics might significantly broaden the range of uses for electronics and transform the way people think about them. This document offers a summary of the most current research in this area. The structure that allows for the transmission of data involves the transfer of information from one channel to another by way of a very flexible film model transistor assisted by an integrated circuit procedure. The semiconductor industry makes extensive use of wall-based carbon nanotubes for the purpose of developing models with improved efficiency. This study provides a comprehensive explanation of single and multi-channel field-effect transistors, both of which are used for the process of data transmission using flexible carbon nanotube transistors in applications such as hearing aid equipment. This research work go through all the recent tweaks to the printing process for sensing and transmitting data from one to another source. All of these modifications are ideal for the mass-production of stretchy and flexible electronics.

Analysis of Natural Language Processing in the FinTech Models of Mid-21st Century 21世纪中期金融科技模型中的自然语言处理分析
Pascal Muam Mah, Iwona Skalna, John Muzam, Lilian Kuyiena Song
FinTech is a digital innovation technology that aims to educate and enable the world on how to create utility values in every activity. Natural language processing is one of the umbrella systems that has unite other innovative technologies behind FinTech. Technological system drivers regarded as "ABCDE" of FinTech consist of Artificial intelligence, Blockchain, Cloud computing, big data, and the internet of things. As communication took the lead in the second half of the 21st century, most companies are moving remotely, leading to much-needed innovation in FinTech. The study presents how natural language processing enables different technologies and advances the technology behind FinTech. The study aims to identify areas of the modern world that can be transformed into a source of finance using the FinTechs drivers of "ABCDE”. The study observed FinTech as a digital Economics that integrates with different aspects of modern technology to create utility values. The study uses the 5 C's of credit as the source of finance for innovative ideas and the 5 P's of marketing as innovative network to reach ultimate FinTech utility values. Results based on the demand and supply analysis indicate that a combination of 5 C's and 5 P's is the bond behind FinTech with the support of the drivers of "ABCDE". Also that the increased demand for goods and services in every economy indicates a fall in the request for credit and vice versa. The study concluded that a well-structured 5 C's and 5 P's is the best route to FinTech technology which is financial freedom to the world.
