The single antenna element exhibits dual resonant modes at around 5.50 GHz and 8.02 GHz and achieved two working bands of 4.27 - 6.34 GHz and 6.59 - 10.05 GHz. The MIMO comprises four fork-shaped radiators orthogonally positioned on 1.6 mm wide FR4 material of size 35 mm ˟ 35 mm. The patches of the MIMO are modified to have an impedance band of 3.78 - 6.47 GHz and 6.47 - 9.5 GHz, which resonates at 4.68, 6.13, and 7.35 GHz. The planned MIMO antenna achieves more than -23 dB (maximum -45 dB) isolation throughout the working bands. The considered MIMO antenna also has a low ECC (around 0.04), high diversity gain (around 10 dB), an ultimate gain of 3.78 dBi, and a maximum efficiency of 81.8%. These advantages and features make the anticipated antenna appropriate for WLAN/Bluetooth/WiMAX/WiFi/C-band/5G sub-6 GHz bands.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122056664","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}

Digital passports provide adamant verification through documentation that tangibly marks the passport owner using biometric techniques because it holds an electronic chip into the passport, also known as an e-passport. The biometric method uses a combination of RFID and fingerprint scanning technology. Notwithstanding, RFID chips have numerous security threats as the information confidentiality can easily be hacked and it is not entirely hassle-free. To get rid of these challenges as a potential remedy, in this paper we propose Hyperledger to secure e-passport management, which in contrast to the public blockchain, is an open-source private blockchain with strong security. When compared to the standard blockchain development framework, the legitimacy of transactions in a private blockchain powered by Hyperledger is substantially distinct, which is enable more effective and quicker transactions while maintaining essential security features. The InterPlanetary File System (IPFS), which has diverse security measures like access control features, non-modifiable data, and immutable history records, and this private ledger have both been used to safeguard private passport information and biometric data.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"22 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126125182","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}

Supplying power to all those clustered houses from the national gridline is difficult and also not economically feasible. Therefore, supplying power from an efficient locally generated power system might be a suitable solution. In this research, a local hybrid power generation and distribution model from a diesel generator, along with hydro, wind, and solar systems are studied for Keokradong, which is one of the most visited remote tourist spots in Bangladesh. Multiple hybrid energy system models are analyzed for optimization using the HOMER software. In addition to hybrid systems connected to the grid, only renewable-based hybrid systems have been examined. Traditional fossil fuel-based energy sources and electricity output per unit cost are compared in a cost per kilowatt-hour comparison. The proposed method can be utilized for powering off-grid clustered areas of hilly and remote regions around the world in a cost-effective and environment-friendly manner.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127863983","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}

There is a significant number of research works about water quality monitoring and controlling system, which are not automated and also have no notification system for abnormal situations. We propose an IoT-based automatic system with a water quality monitoring device and a pH-controlling device that provides water quality information and transmits data through Wi-Fi and Bluetooth for both online and offline conditions. The monitoring device can detect several important water quality parameters like DO, ORP, TDS, Temperature, EC, and pH. Our device can detect the abnormal value of the water and alarm the users through SMS and Email. The pH controlling device can control pH automatically and dose chemicals at required quantities adaptively in need to neutralize. To improve the sensor value, we calibrated pH, TDS, and EC sensors by developing equations from regression analysis. Between different regressions, we choose polynomial regression (order 2) as it shows the highest coefficient of determination value, which is 0.97655, 0.999, and 0.9999 for pH, TDS, and EC sensors, respectively. We implement our monitoring device in four textile industries and measure the quality parameters of the inlet and outlet points of the effluent treatment plant of each factory. Our monitoring device can detect water quality parameters and can identify between less and well-treated water. This monitoring device can be used at any water treatment plant and the pH controlling device can control the pH of any process, especially a wastewater treatment plant.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134502547","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}

Using the same circuit and setting the reference voltage at half the open loop output voltage, the closed-loop system's output voltage remains almost constant for input voltages below the reference value. If the input voltage crosses the reference voltage, the output voltage jumps up somewhat. The closed-loop method is less effective than the open-loop method since the output voltage THD and the input and output current THD of the inductor and capacitor are higher and vary more with voltage. Open loop output voltage THD was 375.06% and closed loop THD was 1742.84% for a 17-volt input.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124012646","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}

The worldwide death rate due to drowsy driving is quite alarming. As the implementation of artificial intelligence (AI) is growing faster, this paper describes an attempt to implement machine learning (ML) to detect drowsiness. 120 videos of 60 participants are collected from the Real-Life Drowsiness Video Dataset made by a research team of the Vision-Learning-Mining Lab from the University of Texas at Arlington. Then Eye Aspect Ratio, Mouth Aspect Ratio, Pupil Circularity, and Mouth Aspect Ratio Over Eye Aspect Ratio, Nose Length, Chin Length, Nose Length Over Chin Length Ratio are extracted as features of each participant using the 3D Face-Mesh 468 facial landmarks system from those videos. After that, each feature is normalized by its mean and standard deviation. Then the CSV dataset is generated using seven initial and seven normalized features. A total of 30000 instances are there in the dataset. A total of eight classification algorithms are implemented to build the model. The dataset is split such that the individual in the train set will not be in the test set to test the proposed model's ability to predict drowsiness for new faces. 5-fold cross-validation is implemented to measure performance for each algorithm. Convolutional Neural Network (CNN) yields maximum accuracy (91.63%). The state of any individual's eye closing, rapid eye blinking, yawning, putting a hand on the mouth during yawning, and head posing too much up or down can be detected as drowsiness by the proposed model.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128065537","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}

Music is a form of art that is highly regarded worldwide. There are many ways that music lyrics affect our daily lives. In the music industry, it is crucial to prevent the reproduction of songs whose lyrics are toxic or unsuitable for children. Our mood might be impacted by listening to particularly toxic or non-toxic music. The listener's experience might be enhanced if the recommendation method eliminates toxicity. In this study, we use machine learning (ML) algorithms to classify lyrics from various musical genres and performers as toxic or non-toxic. Utilizing the Detoxify model, the toxicity score was generated and labelled the songs as toxic and non-toxic based on the scores. The study demonstrates that the configuration using the lyric data set along with TF-IDF vectorization and Ensemble of Logistic Regression, Support Vector Machine and Decision Tree as an algorithm surpasses all other designs with 94% accuracy. This classification will help the authority and policymakers of music industries to categorize the song based on the label and mention in the song description which is not appropriate for the children and set guidelines to prevent toxicity via songs.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121549497","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}

The antenna contains a switchable feed network, a single microstrip antenna and PIN diodes. The antenna also employs a short-ended microstrip-line perturbation for achieving circular polarization. The switchable feed network employs two PIN diodes to control its two branch to achieve two linear (LP) modes switching. A third diode is integrated between the perturbation segment and upper corner of the patch element. By activating the perturbation to function together with the radiating patch element, the same antenna can generate two circular polarization (CP) modes. The concept is examined through simulation. The impedance bandwidth for LP and CP conditions are about 1.6% and 2.6%, respectively. Around 0.7% 3-dB axial ratio bandwidth is observed within the range of interest.","PeriodicalId":131537,"journal":{"name":"2023 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121710889","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}
