The proliferation of conformable devices with embedded wireless capability has propelled the expansion of interconnected devices into a swarm called the Internet of Things (IOT). This allowed the localized sensing while processing is normally done remotely into the cloud. The local sensors need to dissipate low power while providing acceptable performance based on the application. One such sensor is the ubiquitous temperature sensor. Temperature sensing has become a pivotal component in most smart systems for maintaining the device performance at optimum, thereby preventing degradation. Amongst such sensors, solid-state based temperature sensors have proven to provide the widest sensing range as well as promotes integration into a complete system-on-chip. There have been several approaches for the readout circuit either based on MOS or BJT, with either analog or digital outputs. In this work, a low voltage and low power temperature sensor with digital time-based output is presented. The circuit uses a BJT - less current-mode bandgap core incorporating sub-threshold MOS. Temperature dependent output voltages are derived from the core, that drives the source and sink currents of a voltage-frequency converter. The circuit has achieved high linearity of (r2 = 0.99) over the temperature range of −40 to 110 deg C, a power dissipation of just around 30 I-lW at a single supply rail of 1.0 V. The circuit has been designed using TSMC 0.18um technology obtained from MOSIS wafer test runs and was verified using SPICE.
具有嵌入式无线功能的兼容设备的激增推动了互联设备的扩展,形成了一个被称为物联网(IOT)的群体。这允许本地化传感,而处理通常在云端远程完成。本地传感器需要消耗低功耗,同时根据应用提供可接受的性能。一种这样的传感器是无处不在的温度传感器。温度传感已成为大多数智能系统中保持设备性能最佳,从而防止退化的关键组件。在这些传感器中,基于固态的温度传感器已被证明可以提供最宽的传感范围,并促进集成到完整的片上系统。基于MOS或BJT的读出电路有几种方法,具有模拟或数字输出。在这项工作中,提出了一种具有数字时间输出的低电压低功耗温度传感器。该电路采用了结合亚阈值MOS的无BJT电流模带隙铁芯。温度相关的输出电压来自驱动电压-频率转换器的源电流和汇电流的磁芯。该电路在−40至110℃的温度范围内实现了高线性度(r2 = 0.99),在1.0 V的单电源轨下功耗仅为30 I-lW左右。该电路采用TSMC 0.18um技术进行设计,并通过SPICE进行了验证。

COVID-19 has many symptoms and one of the serious symptoms are heart problems and the increase in body temperature. Checking the heart rate and body temperature can still be useful to be included in our daily live to prevent further spread of the virus. We proposed a solution to let the user do a COVID-19 self-detection by using Magic Mirror with IoT -based technology. This Magic Mirror uses two sensors (heart rate and temperature sensor) to measure user's heart rate and body temperature. If the user is suspected of having COVID-19, an alert will be displayed on the Magic Mirror or smartphone to let the user take further necessary action.

One regulation that has been established by governments in most countries to curb the spread of Covid-19 is physical distancing. However, many people still ignore the importance of this regulation. Thus, it is important to develop a system that can help enforcing this regulation. In this paper, we propose a system that can automatically detect the presence of humans in a video frame and measure their distances from each other. Object detection is performed using YOLO v3 and the accuracy of distance measurement is enhanced using Bird's Eye View Transformation. Our experiments show that using this transformation yields an accuracy improvement of up to 20.93% compared to the performance of the system without transformation (i.e., from 74.42% to 95, 35% accuracy).
大多数国家的政府为遏制Covid-19的传播而制定的一项规定是保持身体距离。然而,许多人仍然忽视了这一规定的重要性。因此,开发一个能够帮助执行这一规定的系统是很重要的。在本文中,我们提出了一个可以自动检测视频帧中人类的存在并测量他们彼此之间距离的系统。使用YOLO v3进行目标检测,使用鸟瞰变换增强距离测量的精度。我们的实验表明,与没有进行转换的系统相比,使用这种转换产生的精度提高高达20.93%(即从74.42%提高到95,35%)。

The conventional method of collecting attendance as evidence of student attendance is considered ineffective because it consumes a lot of time and effort. The validity of the data is questionable. There have been many models that have been applied to facial recognition-based attendance systems. However, this model needs much training data so that the model's accuracy is high. In this study, a modification of the deep neural network model for the attendance system is proposed that can work on a small amount of training data. The proposed model is a modification of the DenseNet201 model with batch normalization and average pooling layer. Even though our model's training time is quite long, this model modification can achieve the highest accuracy value of about 90% compared to other pre-trained models, namely ResNet50 and MobileNet.
传统的收集出勤作为学生出勤证据的方法被认为是无效的,因为它消耗了大量的时间和精力。这些数据的有效性值得怀疑。已经有很多模型被应用到基于面部识别的考勤系统中。但由于该模型需要大量的训练数据,因此模型的准确率较高。在这项研究中,提出了一种改进的深度神经网络模型,可以在少量的训练数据上工作。该模型是对DenseNet201模型的改进,具有批归一化和平均池化层。尽管我们的模型训练时间相当长,但与ResNet50和MobileNet等其他预训练模型相比,这种模型修改可以达到90%左右的最高准确率值。

MRI can detect soft tissue that contains a brain tumour. Imaging produced by MRI in brain tumours can not be analyzed easily if done manually. Results in a longer time required. Deep learning is part of artificial intelligence that can analyze data automatically. Mobilenet is one of the methods in deep learning that functions to perform the segmentation process of medical images. Mobile Network is a CNN model with high accuracy and less computation. Therefore, this study proposes the use of Mobile Network architecture to classify brain tumour types. Mobile Network there are various categories. This study finds evidence that the application of Mobile networks improves overall accuracy. The best result from the Mobile Network category was MobileNet V2 140×224, which achieved an accuracy test of 94%.

SARS-CoV-2 has now spread to nearly every part of the world, with the WHO declaring a pandemic because of its rapid spread. One of the diagnostic procedures used to detect the extent of the COVID-19 infection is Chest X-rays. Chest Xrays are commonly used to diagnose lung disorders in the beginning. To improve the accuracy of the computer- aided diagnosis system, a research study assessed how well it can correctly distinguish between non-COVID-19 pneumonia on chest X-ray (CXR) images and COVID-19 pneumonia with the alliance of Artificial Intelligence. COVID-19 pneumonia patients (those that tested positive for COVID-19 antibodies) and non- COVID-19 pneumonia patients (those who did not test positive for COVID-19 antibodies) were included in the analysis. The research was conducted using a standard dataset containing 1563 lung CT scan images of COVID-19 pneumonia and non-COVID-19 pneumonia (virus) patients' samples. The proposed system has two Convolutional Neural Network (CNN) models. The first CNN model using max pooling operation achieved the accuracy, precision, recall, and F1-Score of 98.22%, 98.81 %, 99.33%, and 99.07% respectively and similarly, the second CNN model using average pooling operation performed at 97.82%, 98.60%, 99.13%, and 98.86% respectively
SARS-CoV-2现在已经传播到世界上几乎每一个地方,由于其迅速传播,世界卫生组织宣布了一场大流行。用于检测COVID-19感染程度的诊断程序之一是胸部x光检查。胸部x光片通常用于诊断肺部疾病。为了提高计算机辅助诊断系统的准确性,一项研究评估了它与人工智能联盟在胸部x线(CXR)图像上正确区分非COVID-19肺炎和COVID-19肺炎的能力。COVID-19肺炎患者(COVID-19抗体检测呈阳性)和非COVID-19肺炎患者(COVID-19抗体检测未呈阳性)纳入分析。该研究使用包含1563例新冠肺炎和非新冠肺炎(病毒)患者样本的肺部CT扫描图像的标准数据集进行。该系统有两个卷积神经网络(CNN)模型。使用最大池化操作的第一个CNN模型的准确率、精密度、召回率和F1-Score分别为98.22%、98.81%、99.33%和99.07%,使用平均池化操作的第二个CNN模型的准确率、精密度、召回率和F1-Score分别为97.82%、98.60%、99.13%和98.86%

Academic Customer Service Chatbot Development using TelegramBot API 使用TelegramBot API开发学术客户服务聊天机器人
Pub Date : 2021-09-23 DOI: 10.1109/ICITech50181.2021.9590140

The growth of social media pushes every company, even academic institutions to own more than 1 official social media account, which requires more resources, especially in the Customer Service department. One of the ways to avoid this is by using chatbot, as it can increase cost-efficiency while also giving good responses while interacting with the consumers. The chatbot created in this study is developed using Telegram API and webhook method. Other than that, Telegram Bot is used to exchange messages with the users (in this case, the students), higher education institution administrator, and the chatbot. Simple testing shows that all chatbot's functions run well.
社交媒体的发展促使每个公司,甚至学术机构都要拥有一个以上的官方社交媒体账号,这就需要更多的资源,尤其是在客户服务部门。避免这种情况的一种方法是使用聊天机器人,因为它可以提高成本效率,同时在与消费者互动时也能给出良好的响应。本研究中创建的聊天机器人是使用Telegram API和webhook方法开发的。除此之外,Telegram Bot还用于与用户(在本例中为学生)、高等教育机构管理员和聊天机器人交换消息。简单的测试表明,聊天机器人的所有功能都运行良好。

This paper discusses research that produces a land asset information system called e-asset. The research method used is an experimental method by creating an asset information system. The system created is given to the Salatiga City Regional Finance Agency (BKD) for internal purposes. Fuzzy Algorithm has been implemented in the system so as to make it easier for users from BKD staff to find the location of land assets. The test results by the user stated that the user was satisfied with the satisfaction level of 3.41 (from scale 0 to 5).
