Its sources could be from anthropogenic activities and natural disasters during the past few decades. The purpose of this study is to determine the most appropriate model for forecasting the surface ozone at Shah Alam, Selangor and Larkin, Johor. Several analytical model such as Time Series Regression (TSR), Multiple Linear Regression (MLR) and Artificial Neural Network (ANN) are fitted to the ozone concentration. Model comparison is carried out via performance indicators (RMSE, MSE, R square). The results show that ANN provides better performance compared to TSR and MLR. Between the two stations, Larkin, Johor provides high accuracy in forecasting surface ozone concentrations for each model with minimum MSE (0.000009), RMSE (0.0042) and high value of R2 (0.33) compared to the station in Shah Alam, Selangor.","PeriodicalId":325667,"journal":{"name":"2022 International Visualization, Informatics and Technology Conference (IVIT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128568712","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}

Their emotional response was captured using a wearable device that records both heart rate and skin activity in real time. A total of 5 participants took part in the experiment where the results are classified for intra-subject classification using KNN classifier. In the study, for the classification of intra-subject, the peak accuracy achieved amongst the five participants is 97.7% with HR and EDG signals combined with KNN as the classifier. These results demonstrate that by fusing HR and EDG signals, high-accuracy results can be generated through the use of KNN as the classifier.

Findings show that the majority of the participants have never engaged in cyberbullying, but a few of them had experienced cyberbullying. Findings from the survey revealed that the percentages of female participants as cybervictims are higher (63.7%) than male participants (36.3%), while the percentages of male participants as bullies are higher (52.9%) than female participants (47.1%). The most prominent behaviour of cyberbullies is sending mean messages directly to cybervictims and the most prominent behaviour of cybervictims is being excluded from online groups.","PeriodicalId":325667,"journal":{"name":"2022 International Visualization, Informatics and Technology Conference (IVIT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115873156","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}

Therefore, the purpose of this study is to assess university students' acceptance of video lecture by extending the Technology Acceptance Model (TAM) with internet self-efficacy and learner-content interaction as the extended variable. Data from 390 students were gathered and analysed by Partial Least Squares-Structural Equation Modelling (PLS-SEM). The result shows that both internet self-efficacy and learner-content interaction plays an important role to determine the acceptance of video lecture and all path relationships in TAM were significant. Compared to internet self-efficacy, learner-content interaction have a bigger impact on the perceived usefulness of video lecture. This demonstrates that interaction between the learner and the content is important in deciding the acceptance of video lecture, and that educators should make video lecture brief and engaging so that students would enjoy using them.","PeriodicalId":325667,"journal":{"name":"2022 International Visualization, Informatics and Technology Conference (IVIT)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130868291","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}
