In this paper, we proposed to design a new model of mechanical ventilator based on the Ambu bag automation for the patient who is unable to take breath normally. Here we have automated an Ambu bag for air supply whose inlet is connected with an oxygen cylinder and environmental air and outlet is connected to lung patient. The project device includes a robotic operator which can operate an Ambu bag continuously by compressing and decompressing it. The robotic operator is a Computer-Aided Manufacturing (CAM) arm that is controlled by a single microcontroller for operating on the Ambu bag from outside. It has a great advantage of using a single adult Ambu bag to deliver necessary air to all aged lung patients by setting different controlling modes with respect to age with reducing the necessity of pediatric Ambu bag and infant Ambu bag. By considering all of the physiological parameters, we have added three modes namely Adult mode, Pediatric mode, and Child mode. Each mode is included by different respiratory rate and tidal volume to be friendly with their corresponding subject. The proposed device can detect the air pressure and temperature from the Ambu bag outlet to make feedback for preventing the lung harm of the patient and display the parameters using an LCD. All medical data can be transferred via a communication protocol to an Android or iOS phone for telemedicine purposes in real-time. The overall system is portable, small in size (45cm×25cm×35cm), low weighted, time-efficient, and cost-effective. There is no need for training or the study of an operator about the proposed system to handle the device for the benefit of automation of the device.
在本文中,我们提出了一种基于Ambu袋自动化的新型机械呼吸机,用于无法正常呼吸的患者。在这里,我们已经自动化了一个用于供气的急救袋,它的入口与氧气瓶相连,环境空气和出口与肺部病人相连。该项目装置包括一个机器人操作员,它可以通过压缩和解压来连续操作Ambu袋。机器人操作员是一个计算机辅助制造(CAM)手臂,由单个微控制器控制,从外部操作Ambu袋。使用单个成人急救袋,根据年龄设置不同的控制模式,为所有老年肺部患者输送必要的空气,减少儿科急救袋和婴儿急救袋的必要性,具有很大的优势。考虑到所有的生理参数,我们增加了三种模式,即成人模式,儿科模式和儿童模式。每一种模式都包含了不同的呼吸频率和潮气量,以与相应的受试者友好。该装置可以检测安布袋出口的气压和温度,并对其进行反馈,以防止对患者的肺部伤害,并通过LCD显示参数。所有医疗数据都可以通过通信协议传输到Android或iOS手机上,用于实时远程医疗。整个系统便携、体积小(45cm×25cm×35cm)、重量轻、省时、经济。为了设备的自动化,操作人员不需要对所建议的系统进行培训或研究来操作设备。

In this paper, a simple geometric structured Photonic crystal fiber (PCF) based temperature sensor is proposed and analyzed theoretically. The designed sensor considered polydimethylsiloxane (PDMS) as a temperature dependent analyte to sense the variation of temperature with its surroundings. To enhance the sensitivity and avoid corrosion due to oxidation, gold (Au) film is used as plasmonic material. While analyzing the performance of the sensor, the finite element method (FEM) is utilized. Also, performance characterization is done altering the design parameters, e.g., pitch, air-holes diameter, and thickness of the gold layer. The results reveal a maximum possible spectral sensitivity of 4.67 nm/°C, with the detection range 30 °C to 90 °C. The sensor also exhibits a standard FOM valuing of 0.05838 /°C and a resolution of 3 × 10−2 °C. Considering simple structure and excellent spectral sensitivity, the proposed sensor can be applied in myriad fields to measure the temperature.

The highest invading cancer among the women is breast cancer. Early detection of breast cancer is the higher chance of the patient being treated. In this study, we have proposed an ensemble method named stacking classifier which combines multiple classification techniques and efficaciously classifies the benign and malignant tumor. “Wisconsin Diagnosis Breast Cancer” dataset culled from the UC Irvine Machine Learning Repository has been used for our experiment. We applied different classification techniques over the dataset and tuned their parameters to improve accuracy. We chose the three best classifiers for our proposed method. Generally, our proposed Stacking classifier combined the results of those best classifiers using meta classifier and provided 97.20% accuracy for breast cancer prediction. Performance of different data mining approaches have been evaluated rigorously through different evaluation metrics.

Epilepsy is a neurological disorder that causes abnormal behavior and recurrent seizures due to unusual brain activity. This study has attempted to predict seizures in epileptic patients through the process of feature extraction from EEG signals during preictal/ictal and interictal periods, classification and regularization. EEG signals from various parts of the brain from 10 epileptic patients are considered. Fast Fourier Transform (FFT) is used to determine the three features-the phase angle, the amplitude and the power spectral density of the signals. To classify the signals, these features are then used along with Support Vector Machine (SVM) as the classifier. Furthermore, regularization is used to make better predictions i.e. increase prediction accuracy and decrease the rate of false alarm. Finally, the proposed approach is tested on CHB-MIT Scalp EEG data set and it is able to predict epileptic seizures 25 minutes on average before the onset of the seizure with 100% accuracy and a low false-alarm rate of 0.46 per hour. This study intends to contribute to the development of better and advanced seizure predicting devices in the medical field.
癫痫是一种神经系统疾病,由于大脑活动异常,会导致异常行为和反复发作。本研究试图通过对癫痫患者发作前/发作期和发作间期的脑电图信号进行特征提取、分类和正则化来预测癫痫患者的发作。本文对10例癫痫患者的脑电信号进行了分析。利用快速傅里叶变换(FFT)确定信号的三个特征——相角、幅值和功率谱密度。为了对信号进行分类,然后将这些特征与支持向量机(SVM)一起用作分类器。此外,正则化用于更好的预测,即提高预测精度和降低误报率。最后,在CHB-MIT头皮脑电图数据集上进行了测试,该方法能够在癫痫发作前平均25分钟预测癫痫发作,准确率为100%,每小时误报率为0.46。本研究旨在为医学领域开发更好、更先进的癫痫发作预测设备做出贡献。

Depression is a psychological disorder that affects over three hundred million humans worldwide. A person who is depressed suffers from anxiety in day-to-day life, which affects that person in the relationship with their family and friends, leading to different diseases and in the worst-case death by suicide. With the growth of the social network, most of the people share their emotion, their feelings, their thoughts in social media. If their depression can be detected early by analyzing their post, then by taking necessary steps, a person can be saved from depression-related diseases or in the best case he can be saved from committing suicide. In this research work, a hybrid model has been proposed that can detect depression by analyzing user's textual posts. Deep learning algorithms were trained using the training data and then performance has been evaluated on the test data of the dataset of reddit which was published for the pilot piece of work, Early Detection of Depression in CLEF eRisk 2017. In particular, Bidirectional Long Short Term Memory (BiLSTM) with different word embedding techniques and metadata features were proposed which gave good results.

The mechanical properties of Gallium Nitride (GaN) nanowire has drawn considerable attention of researchers due to its application as electronic and semiconducting material. It has been successfully deployed in LEDs, transistors, Radars, Li-Fi communication system and many other electronic devices. In this research work, Molecular Dynamics simulations have been performed to explore the temperature-dependent mechanical properties of Zinc-Blende (ZB) GaN nanowire for tensile simulation. Stillinger-Weber (SW) potential has been employed to define the inter-atomic interactions between atoms in the GaN crystal. The temperature has been varied from 100K-600K and corresponding mechanical properties have been reported. To explore the nanowire size effect on the mechanical properties, the cross-sectional area of the nanowire has been varied for the temperature of 300K. Investigations suggest that increment of temperature results in the failure of GaN nanowire at a lower value of stress 37.96 GPa to 30.06 GPa and corresponding Young's Modulus decreases as well. We have calculated ultimate tensile stress and Young's modulus as 36.2 GPa and 189.3 GPa respectively at 300K for 13.37 nm2GaN nanowire. Our simulations results show that size has a significant effect on ultimate tensile stress and Young's Modulus of GaN nanowire. It has been found that as cross-sectional area increases both ultimate tensile stress and Young's modulus increases. Finally, the fracture behavior of GaN nanowire has also been reported from the atomistic simulation results. It has been found that 13.37 nm2GaN nanowire failed by creating a fracture plane along <111> direction of the nanowire axis and indicates the brittle nature of GaN nanowire.
氮化镓(GaN)纳米线的力学性能由于其作为电子和半导体材料的应用而引起了研究者的广泛关注。它已成功应用于led、晶体管、雷达、Li-Fi通信系统和许多其他电子设备。在本研究中,我们采用分子动力学模拟的方法来探索锌-滑石(ZB) GaN纳米线的力学性能随温度的变化规律。Stillinger-Weber (SW)势被用来定义GaN晶体中原子间的相互作用。温度在100K-600K范围内变化,并报道了相应的力学性能。为了探索纳米线尺寸对力学性能的影响,在300K温度下改变了纳米线的横截面积。研究表明,温度升高导致GaN纳米线在较低应力值(37.96 GPa ~ 30.06 GPa)下失效,杨氏模量也随之降低。我们计算出13.37 nm2GaN纳米线在300K下的极限拉伸应力和杨氏模量分别为36.2 GPa和189.3 GPa。模拟结果表明,尺寸对氮化镓纳米线的极限拉伸应力和杨氏模量有显著影响。随着截面面积的增大,极限拉应力和杨氏模量均增大。最后,从原子模拟结果也报道了氮化镓纳米线的断裂行为。实验发现,13.37 nm2GaN纳米线沿纳米线轴线方向形成断裂面失效,表明GaN纳米线具有脆性。

We have calculated ultimate tensile stress and Young's modulus as 36.2 GPa and 189.3 GPa respectively at 300K for 13.37 nm2GaN nanowire. Our simulations results show that size has a significant effect on ultimate tensile stress and Young's Modulus of GaN nanowire. It has been found that as cross-sectional area increases both ultimate tensile stress and Young's modulus increases. Finally, the fracture behavior of GaN nanowire has also been reported from the atomistic simulation results. It has been found that 13.37 nm2GaN nanowire failed by creating a fracture plane along <111> direction of the nanowire axis and indicates the brittle nature of GaN nanowire.","PeriodicalId":6721,"journal":{"name":"2020 IEEE Region 10 Symposium (TENSYMP)","volume":"21 1","pages":"22-25"},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91176038","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}

This paper presents the design and evaluates the system performance of one-kilowatt capacity asynchronous and synchronous buck converter based solar-powered charging systems for battery-driven electric vehicles. The dc motor-operated three-wheeler rickshaw was taken for testing the systems, where a battery bank containing four series-connected sub-colloid storage type batteries of each with a capacity of 12V, 120Ah has been used. PSIM simulation software has been used to evaluate the performances of these two types of battery charging systems. Hardware prototypes of these two types of charging systems have also been made and an experimental testbed comprising a 48V battery bank of 100Ah capacity with a charging current of 6A was performed. The experimental results have also been evaluated and compared.

Sentence generation serves the process of predicting relevant words in a specific sequence. The purpose of this research is to come up with a method for generating sentences while maintaining proper grammatical structure. Here, we have implemented a sentence generation system based on Long Short-Term Memory (LSTM) architecture. Our system generally follows the basics of word embedding where words from the dataset get tokenized and turned into vector forms. These vectors are then processed and passed through a Long Short-Term Memory layer. Successive words get generated from the system after each iteration. This process winds up generating relevant words to form a sentence or a passage. The results of the system are pretty convincing compared to different existing methods.
句子生成服务于按照特定顺序预测相关单词的过程。本研究的目的是提出一种生成句子的方法,同时保持适当的语法结构。在这里,我们实现了一个基于长短期记忆(LSTM)架构的句子生成系统。我们的系统通常遵循词嵌入的基础,其中来自数据集的词被标记并转换为向量形式。然后对这些向量进行处理并通过长短期记忆层。每次迭代之后,系统会生成连续的单词。这个过程最终会生成相关的单词来组成一个句子或一篇文章。与现有的不同方法相比,该系统的结果非常令人信服。

Building Decentralized Image Classifiers with Federated Learning 用联邦学习构建去中心化图像分类器
Pub Date : 2020-06-05 DOI: 10.1109/TENSYMP50017.2020.9230771

The commercial use of neural networks has been greatly curbed by data privacy concerns. As long as the accumulation and use of private data is regarded necessary for integrating neural networks into products, consumers will be reluctant to use or allow access to any deep learning integrated product and producers will be equally deterred from leveraging deep learning for performance improvement. Federated learning was first introduced as a solution to this conundrum in a 2016 paper published by Google titled Communication-Efficient Learning of Deep Networks from Decentralized Data [1]. In this study, we examine how the performance of a decentralized image classifier compares to that of a centralized one. The performance of an image classifier trained across ten devices was compared to a model built with the same architecture but trained centrally on one corpus of training data. The outcome demonstrates that the decentralized model compares quite well to the centrally trained classifier in terms of accuracy, precision and recall.
神经网络的商业用途受到数据隐私问题的极大限制。只要个人数据的积累和使用被认为是将神经网络集成到产品中所必需的,消费者将不愿意使用或允许访问任何深度学习集成产品,生产者也将同样被阻止利用深度学习来提高性能。在谷歌2016年发表的一篇题为《从分散数据中高效学习深度网络》的论文中,联邦学习首次作为解决这一难题的方法被引入[1]。在本研究中,我们研究了去中心化图像分类器与集中化图像分类器的性能比较。将跨十个设备训练的图像分类器的性能与使用相同架构构建但在一个训练数据语料库上集中训练的模型进行比较。结果表明,在准确率、精度和召回率方面,分散模型与集中训练的分类器相比要好得多。
