Conventionally, a horizontal axis wind turbine (HAWT) with single rotor is widely used in WF applications, and the blade root region (adjacent to the hub) of a HAWT suffers from aerodynamic incompetence due to various non-aerodynamic limitations. WF performance is also significantly reduced due to aerodynamic interactions between turbines. To address this problem, a dual rotor wind turbine (DRWT) for permanent magnet synchronous generator (PMSG) and squirrel cage induction generator (SCIG) is built in this paper to improve the WF's performance. The DRWT is made up of two types of rotors: main and secondary. In comparison to HAWT, the proposed DRWT mechanism will extract more mechanical resources. When the wind speed is poor, the overall architecture will function properly. The PSCAD/EMTDC software is used to build and evaluate a hybrid power system that includes a robust DRWT-PMSG, DRWT- SCIG model, and a traditional power plant. According to simulation results, the built DRWT can extract more power than a traditional single rotor HAWT.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"63 1-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132937904","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}

Optimum sizing of the hybrid RES is necessary to ensure that renewable energy sources penetrate. Improper sizing may result in higher initiating costs or an inability to meet load demand under various weather conditions. By analyzing with Hybrid Optimization Multiple Energy Resources (HOMER pro), this study shows the ideal hybrid energy system that provides the lowest cost of energy production, emissions, and so on. This study provides a grid-connected hybrid power system model based on metrological data collected from a residential building in Mohammadpur, Dhaka, Bangladesh. Solar energy is used as a sustainable energy source thus the cost of the system was decreased, which is also environmentally friendly. This renewable energy also helped to minimize the levelized cost of energy (COE). The conclusion estimates operational costs, production costs, net present cost, and energy cost for the two combinations evaluated for the proposed microgrid system. According to the simulation results, delivering power to the load via a microgrid would be a viable and cost-effective solution.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133605318","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}

To date, computer vision (CV) is considered the most practical technique to detect and count the leftover pellets. It is primarily economically viable, has broad application to other fields, and has rapid advances in computing algorithms such as deep learning (DL). This study introduces a hybrid of aggregated channel feature (ACF) detector, a non-DL object detector, and Sobel edge operator, a basic CV algorithm, to detect and count the excess floating feed pellets in water surface images with varying background noises. The ACF was used to detect the region proposal (RP) candidates of leftover pellets and discriminate the RP with low confidence scores. The selected RPs for a group of pellets, i.e., greater than 400 pixels, were further processed using the Sobel edge operator to count each pellet in the RPs. In contrast, the RPs with a pixel size of 400 are considered as a single pellet. Then, all the counted pellets in each RPs were added. This approach resulted in a considerable pellet counting estimator with r2 of 0.8 and NRMSE of 11.55% with a selected confidence score greater than 60. The main advantage of the proposed technique is that it only requires a substantially lower computational cost than a DL-based object detector.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127204201","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}

Operators employ state estimation algorithms to determine the current prevailing conditions of the grid. Recently false data injection attacks have shown their detrimental effects on the state estimation techniques by bypassing the standard statistical bad data detection algorithm. Such kind of an attack vector injection is possible when the attacker can possibly access the meters or the communication channels and has sufficient resources to modify the measurement data. This work showcases the real time attack vector implementation using OPNET followed by its effective diminution using the data diode scheme. Using such test-bed it can be shown that the proposed data diode scheme can not only prevent the injection of attack vectors in the communication channels but also can effectively mitigate the effects of false data intrusion on the grid. Although such schemes are costly, still it shows a potential physical defending policy of the meters from such genres of attack. An extensive analysis on the standard IEEE 14 bus test system provides a clear insight regarding such aforementioned propositions.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126718198","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}

However, availability of internet access is limited to some sectional configuration areas distinctively on farm sites. The contribution of the work is twofold: 1) Design a decentralized cluster of local networks 2) provide resilient internet provision through cluster-based network architecture. Local network packets of the setup such as environmental sensor parameters and real time monitoring cameras, rather than being stopped at the gateway, are instead clustered into IP packets, and then locked and directed from the gateway to the best WAN online port available. The basic clustering and locking procedure form an application overlay of the local network over the Internet. Instead of varying WAN IP port, all networks will have unique and fixed access of it, that allows them to query and interact with the local network directly via a largely transparent gateway. The system is evaluated by measuring the received signal strength indicator (RSSI) received by the local networks from the network gateway up to the locked WAN IP port.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130326269","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}

Water leakage and contamination cannot be identified in existing systems. We proposed an Internet of Things (IoT) based Water monitoring system to monitor quality of water, leakages, contamination, and to manage pipeline networks. Generally, water flow starts from an administrator tank (Water head tank) through a pipeline. The value of the flow sensor at the admin tank is treated as a reference and all remaining long-distance nodes (flow sensors) are compared with it and identify the possible leakages. If any leakages are found, then that information is sent to the cloud. Admin and repair person will get notification from the cloud. In this paper, the proposed system measures five water parameters like Potential of Hydrogen (pH), Total Dissolved Solids (TDS), Temperature, Turbidity and Flow Rate. All this data is transmitted to the Amazon Web Services (AWS) cloud platform hosted in Firebase, and made available to both the admin dashboard and User mobile application (App). If any deviations occur in water quality, then the user will get the notification and he/she can take a precise decision. Every end-user is provided with a mobile app that engages them to see their usage and water quality. Users can be charged based on the usage of water and the app provides them the facility to pay for the water used and the admin can control all the Smart Valves in a grid when needed. Admin Dashboard consists of all the functionalities required to manage users, identify leakages, and check historical data.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128881065","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}

However, this work sheds light on the method of hatching duck eggs which maintains a suitable environment around the eggs through an automated and low cost device by controlling temperature (T) and relative humidity (RH). This paper presents a control strategy for automatic temperature and relative humidity control systems for the egg/s hatching procedure for rural areas people or unprivileged communities in the developing countries. One of the best outcomes of this work is the proper hatching procedure steps shown from the beginning to the end. Moreover, for a better understanding and outcomes, the research work has been done under a poultry farm in Charsita village, Lakshmipur, Bangladesh for 6 consecutive months of 2020. The experiment (egg/s hatching) has been conducted under an ice-box. Furthermore, a microcontroller (ATmega328p) is used to monitor the temperature and relative humidity by receiving data from the sensor DHT22 and manipulating the appropriate temperature and humidity using a logic algorithm code. Egg/s need a constant temperature and relative humidity of 35.6 °C to 37.8 °C and 60% to 80%, respectively. Nonetheless, an LCD (16*2) with a matrix keypad (4*4) has been integrated into the unit, allowing farmers to easily set, run, and monitor the appropriate temperature and relative humidity levels within the ice-box. Finally, the results of sensor testing, system device management, and performance rates are recorded to ensure the research's success.","PeriodicalId":117626,"journal":{"name":"2021 IEEE 9th Region 10 Humanitarian Technology Conference (R10-HTC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117070572","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}
