Face masks are considered protective equipment that has the ability to safeguard humans from vulnerable situations. Although there exists a wide range of masks specifically designed for diverse purposes, there is a terrible lack of concern regarding proper usage. Consequently, the generalization of their usage can cause many life-threatening problems. As a result, a system that can detect the type of face mask can play a life-saving role to ensure the proper usage of these safety gear. With this aim, a custom dataset was built by manually labeling face mask images which include 8 classes. Scratch CNN and four transfer learning models have been implemented and their performance was thoroughly evaluated and assessed on multiple criteria to select the best one. Based on the investigation, it is found that SSD MobNet V2 achieved the highest accuracy of 83%. The developed system takes real-time video stream input from the camera and can detect the type of mask in different conditions.

As most of the areas in Bangladesh have adopted an underground drainage system, it is very important that this system work in a proper manner to keep the country clean, safe, and healthy. Failure to maintain regular monitoring of the drainage system results in the contamination of rainwater with drainage water, which spreads infectious diseases. This paper presents the implementation and design of a microcontroller-based drainage system for monitoring and maintaining the continuous movement of rainwater inside an underground drainage system remotely from a workstation. Using the Internet of Things (IoT), various parameters like water level, block detection, rainfall rate, etc. are monitored and stored on the cloud for analysis. The system also provides a forecast using Fisher's Rules. This enables the person in charge to take the necessary actions regarding the issue and send warning signals to the public.

Bangladesh is a highly populated nation in the globe where 76% people live in the remote regions and 24% in metropolitan areas. Peoples living in distant places are encountering problems having no access to energy. In addition, electricity sector of Bangladesh relies on the fossil fuel like natural gas, coal, oil that are limited in supply. Huge potentiality of renewable resources like solar, biogas/biomass, wind, hydro might be an excellent solution for minimizing electricity crises. In this study, hybrid renewable energy like solar, wind and biogas resources are assessed in terms of availability and energy recovery potential. A field study has been done to gather the information regarding population, load demand, biogas and solar resources of the chosen rural regions of Chapai-nawabgonj district. Then a solar PV-wind-biogas based 100 kW hybrid power generating system is constructed utilizing HOMER (Hybrid Optimization Model for Electric Renewable). In comparison to all other combinations, the modeling results demonstrate that the combined Solar-PV-Wind-Diesel system has the lowest COE (cost of electricity) and NPC (net present cost). In Bangladesh's Chapai-Nawabgonj district, electricity produced by the planned hybrid power generating system may be used in some of the area's most distant locations. This technology lowers energy costs per kWh and CO2 emissions, which contributes to the creation of a sustainable environment.

Due to the presence of hazardous gasses at high levels, some regions are physically very difficult for humans to approach. This paper presents a project idea seeks to simplify the task of monitoring the air quality in hard-to-reach areas. This would help to know the air quality of that region. The system was developed using the Arduino Uno microcontrollers and the NodeMcu microcontroller is used in the IoT interfacing of the system. The real-time monitoring, analysis of the air quality, and data logging to a remote server, which allows for continuous data updating online, are all features of the air pollution monitoring system. The system's specified air quality readings were precise. This system detects air pollutants including Carbon Monoxide (CO), Ozone (O3), Nitrogen Dioxide (NO2), Particular Matter (PM), and Sulfur Dioxide (SO2) and the result was displayed on the LCD interface and could be accessed via the cloud on any smart device using the internet with hazardous limits indications.

Refugee identity documentation is a sensitive process that a host country must go through to avoid unnecessary adversities. Flawless identity documentation is not only important to restrict unwanted population influx, but also to provide public and private services only to the rightful citizens of a country. The established refugee identity system process is faulty, inefficient, and resource intensive. The government spends an incredible amount of time and assets to document the refugees to incur a loss eventually in the inflow of illegal citizens. Our research is keen to change the current refugee identity documentation process. In this paper, we demonstrate a blockchain solution to enhance the effectiveness of the current identity management procedure. We clearly demonstrate the solution using a blockchain-based system where no refugee can become the host country's citizen. We also demonstrate the blockchain architecture along with the internal activities. We present some techniques used in a blockchain to enhance the system's data security and privacy.

This study shows a prototype for detecting lung effects using microwave imaging. Continuous monitoring of pulmonary fluid levels is one of the most successful approaches for detecting fluid in the lung; early Chest X-rays, computational tomography (CT)-scans, and magnetic resonance imaging (MRI) are the most commonly used instruments for fluid detection. Nonetheless, they lack sensitivity to ionizing radiation and are inaccessible to the general public. This research focuses on the development of a low-cost, portable, and noninvasive device for detecting Covid-19 or lung damage. The simulation of the system involved the antenna design, a 3D model of the human lung, the building of a COMSOL model, and image processing to estimate the lung damage percentage. The simulation consisted of three components. The primary element requires mode switching for four array antennas (transmit and receive). In the paper, microwave tomography was used. Using microwave near-field imaging, the second component of the simulation analyses the lung's bioheat and electromagnetic waves as well as examines the image creation under various conditions; many electromagnetic factors seen at the receiving device are investigated. The final phase of the simulation shows the affected area of the lung phantom and the extent of the damage.

M2M refers to the use of sensors and intelligence to connect physical assets such as physical assets or consumer devices to the Internet and these things in turn will connect to the Internet through the Internet of Things (IoT) communications. Since the vision and model have existed, the number and types of connected things have grown, along with technologies for capturing, processing, and sharing data. This m2m technology was founded on mesh technology, and the communication protocol is MQTT (Message Queuing Telemetry Transport. It is a lightweight messaging protocol developed for constrained devices and networks with high latency, low capacity, or unstable networks. In this paper, it will be constructed with two solar-powered charging stations. There are twoseparate batteries for two charging stations. One is Main charging station and another is supportive charging station. If the voltage of one battery drops, another station will share the voltage from the battery it has. For whatever reason that fails, the battery will be charged from the national grid and supplied to the load. All the data, notification & information will be stored in a local server.

A grid tie inverter (GTI) requires a proper adjustment of Power Factor (PF) to provide efficient power supply to the utility power grid while converting the DC power to an adjustable grid based AC power. Additionally, the inverter has to be designed based on a minimal total harmonic distortion that occurs on the utility power grid voltage and current while such conversion occurs. Presented herein is a power and control system architecture of a 500 W inverter for achieving a better power factor (PF) and which can efficiently diminish the harmonic content out of the utility power grid. Implementing an inverter that consists of a full-bridge switching configuration, the single stage of DC-to-AC power conversion is inventively designed hereby to attain maximum power factor as well to generate a minimum THD containing sinusoidal output voltage that is adjustable with the grid, is the novel feature of this paper.
并网逆变器(grid - tie inverter, GTI)在将直流电源转换为基于电网的可调交流电源的同时，需要适当调节功率因数(Power Factor, PF)，为公用电网提供高效的供电。此外，逆变器的设计必须基于在这种转换发生时对公用电网电压和电流产生的最小总谐波畸变。本文提出了一种500w逆变器的电源和控制系统架构，以获得更好的功率因数(PF)，并能有效地降低公用电网的谐波含量。本文的新颖之处在于，实现了一种由全桥开关配置组成的逆变器，创造性地设计了单级直流到交流的功率转换，以获得最大的功率因数，并产生最小的THD，其中包含可随电网调节的正弦输出电压。

Additionally, the inverter has to be designed based on a minimal total harmonic distortion that occurs on the utility power grid voltage and current while such conversion occurs. Presented herein is a power and control system architecture of a 500 W inverter for achieving a better power factor (PF) and which can efficiently diminish the harmonic content out of the utility power grid. Implementing an inverter that consists of a full-bridge switching configuration, the single stage of DC-to-AC power conversion is inventively designed hereby to attain maximum power factor as well to generate a minimum THD containing sinusoidal output voltage that is adjustable with the grid, is the novel feature of this paper.","PeriodicalId":389360,"journal":{"name":"2023 3rd International Conference on Robotics, Electrical and Signal Processing Techniques (ICREST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131126263","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}
