Studies have explored verbal and written communications related to suicide, including analyzing suicide notes, online discussions, and social media posts to identify linguistic and content markers that may help in early detection and intervention. The primary purpose of this study is to detect signs of risk of suicide/self-harm in social media users by investigating several frequency-based featuring and prediction-based featuring methods along with different baseline machine learning classifiers. The algorithms applied for analysis are Decision Tree, K-Nearest Neighbors, Random Forest, Multinomial Naïve Bayes, and SVM. Our experimental results showed that the best performance is obtained by the FastText embedding with SVM model having the highest accuracy of 93.76% which outperforms other baselines. The aim of this work is to learn the significance of analysis and do a comparative study of algorithms to find the best suited algorithm.","PeriodicalId":365290,"journal":{"name":"Asian Journal of Electrical Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132849226","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 primary goal of adopting phase change material is to increase performance, cooling duration, capacity for storage, and to sustain the steady cooling effect for a longer length of time during power outages. In experimental set up it is decoded to use Inorganic and Eutectic phase change materials which is encapsulated in plastic containers inside the vaccine storage. The project will involve collecting data from sensors installed in cabinet and using machine learning algorithms to analyse the data and generate insights. The results of the project can be used to inform best practices for vaccine storage and contribute to the development of more efficient and effective cabinet management systems. This project explores the use of machine learning techniques to optimize the storage of vaccines in cabinet. Proper storage is critical to maintain vaccine efficacy, and therefore it is important to ensure that the temperature and humidity are kept within specific ranges. Machine learning models can be trained to predict the temperature and humidity levels in the cold rooms and to detect anomalies that may indicate a potential problem. This can help improve the monitoring and maintenance of the cabinet and reduce the risk of vaccine spoilage. Machine Learning algorithms like Regression and Classification are used on web-app because they provide us with continuous as well as discrete value as an output. Libraries like pandas, Numpy, sklearn, matplotlib are used to predict along with visualization because of which it will be possible to forecast the actual aspects like temperature and humidity. User Interface has also been developed which acquires input from any user and displays the data according to user’s inputs. The project will involve collecting data from sensors installed in cabinet and using machine learning algorithms to analyse the data and generate insights. The results of the project can be used to inform best practices for vaccine storage and contribute to the development of more efficient and effective cabinet management systems.","PeriodicalId":365290,"journal":{"name":"Asian Journal of Electrical Sciences","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132044397","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}

It can improve energy efficiency by optimizing chiller operation based on predicted load requirements. It can enhance system reliability and reduce maintenance costs by detecting and diagnosing faults in advance. Furthermore, it can enable data-driven decision-making, enabling operators to make informed choices based on accurate predictions and insights. This implementation aims to leverage machine learning techniques to optimize the performance and energy efficiency of a chiller system. Chiller systems are widely used in various industries for cooling purposes, and their efficient operation is critical to reducing energy consumption and operational costs. By employing machine learning algorithms, this implementation aims to analyze historical data, understand patterns, and develop predictive models to optimize chiller system performance. The implementation process involves several steps. First, historical data from the chiller system, including sensor measurements, operating parameters and energy consumption, is collected and preprocessed. The data is then split into training and testing sets. Next, suitable machine learning algorithms, such as regression, classification, or time-series forecasting models, are selected based on the specific goals and requirements of the chiller system. Overall, this implementation demonstrates the potential of machine learning to optimize chiller system performance, reduce energy consumption, and improve operational efficiency.

In distribution power systems, emerging scenarios need some compelling protection efforts. In the last few decades, a lot of innovations such as Advanced Metering Infrastructure (AMI) have made incursions into the electric power sector. The development of AMI has fostered the integration of smart meter systems in microgrids and distribution networks with the capability to permit communication between electricity customers and utility service companies. Control and monitoring of information with regard to energy consumption is a phenomenal task that requires advanced information and communication technologies including some other essential parameters in real-time. Smart meters integrated into microgrids enable the utility to develop an electric power business efficiently. Therefore, this paper presents a study on the experimental on overview and investigation of the energy consumption pattern and data validation of smart meters installed in a smart grid project deployed by PowerGen in Nigeria. In addition, a comprehensive review of the security threats and control measures in microgrids was also presented. The results obtained show that utilities can increase their situational responses in a timely manner to the occurrence of abnormalities in the power grid to provide better monitoring and control services to energy customers.","PeriodicalId":365290,"journal":{"name":"Asian Journal of Electrical Sciences","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125359135","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}

Four vertically oriented identical rectangular patch antennas are used  to form a hollow cylinder of rectangular cross section. The direction of radiation of each antenna is thus oriented at 900 with respect to its two adjacent antennas providing good isolation between adjacent antennas in this compact MIMO system. Each antenna element has the dimensions of 0.30λx0.38λx0.012λ. The whole MIMO antenna has the outer dimensions of 0.38λx0.38λx0.30λ. The uniqueness of the proposed MIMO antenna is that the inner space of the hollow cylindrical structure can be used for hosting the associated signal processing unit of the whole system. Performance parameters of the proposed MIMO antenna are investigated using Computer Simulation Technology (CST). Envelope Correlation Coefficient (ECC) less than 0.033 and almost 10dB Diversity Gain (DG) are obtained at 2.4 GHz for this simple and compact antenna system. Ratio of Mean Effective Gain (MEG) of any two antennas is less than 0.02dB.
