Financial and non-financial attributes related to the bankruptcy exposure show multicollinearity, and the redundant information was identified and removed. The common period for the variables is from 1999-2021, which includes the period of COVID-19 pandemic. Models with a combination of financial and non-financial attributes further reduce the deviation between the estimated standard deviation of the residuals and the marginal standard deviation of the bankruptcy risk in comparison to models without the combination. The best model provides improvements in terms of the mean of the absolute errors (MAE), mean of absolute percentage errors (MAPE), and mean absolute scaled errors (MASE). Furthermore, all determinants in the best model are statistically significant. We suggest that the opportunity for optimisation, including total movements of passenger, cargo and mail, could reduce the company’s bankruptcy exposure. Findings indicate that reducing the financial leverage could improve the financial distress risk while liquidity, net operating margin, and asset turnover are positively contributed to the financial stability of the largest airport operator in Malaysia. If the marginal average of annual exposures to bankruptcy of 4.04% continues linearly into the future, the company is expected to transition from being financially stable to experiencing financial distress in 2030.","PeriodicalId":319652,"journal":{"name":"2022 IEEE International Conference on Computing (ICOCO)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123978567","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}

Although a number of stress markers have been deployed, there are still issues involved with using these kinds of approaches. By developing a speech-based stress detection system, it could solve the problems faced by other currently available methods of detecting stress since it is a non-invasive and contactless approach. In this work, a fusion of Teager Energy Operator (TEO) and Mel Frequency Cepstral Coefficients (MFCC) namely Teager-MFCC (T-MFCC) are proposed as the speech features to be extracted from speech signals in recognizing stressed emotions. Since stressed emotions affect the nonlinear components of speech, TEO is applied to reflect the instantaneous energy of the components. Convolutional Neural Network (CNN) classifier is used with the proposed T- MFCC features on the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS) corpus. The proposed method (T-MFCC) had shown a better performance with classification accuracies of 95.83% and 95.37% for male and female speakers respectively compared to the MFCC feature extraction technique which achieves 84.26% (male) and 93.98% (female) classification accuracies.","PeriodicalId":319652,"journal":{"name":"2022 IEEE International Conference on Computing (ICOCO)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127728693","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}

Segmentation of brain tumors involves distinguishing normal brain tissue from malignant tissue. When evaluating brain tumors, it is possible to determine the existence of tumor tissue quickly. However, accurate and reproducible segmentation and characterization of anomalies are not readily achievable. Consequently, several researchers have proposed various biomedical image segmentation methods to distinguish between tumor and normal brain tissue reliably. However, state-of-the-art segmentation has not been achieved by the existing brain tumor segmentation models, and they often come with high model complexity. Att-Sharp-U-net, a model influenced by the actual U-net model utilized in various medical image segmentation research, is presented as a contribution by this study. Two critical alterations to the underlying U-net model have been incorporated into the model: a grid-based attention block and a sharp block. By doing this, we were able to address the constraints of the U-net model while simultaneously enhancing segmentation performance with increasing negligible computational complexity. Experiments on the Brats2020 dataset, a recent publicly available benchmark dataset in brain tumor segmentation, showed that the proposed model improved segmentation performance with a dice score of 0.9275 and Jaccard score of 0.8684 when compared to the baselines.","PeriodicalId":319652,"journal":{"name":"2022 IEEE International Conference on Computing (ICOCO)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114410928","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}

This image parsing method uses pre-trained model, DeepLabv3, to detect objects common to traffic CCTV images such as road and vehicles. Supervised learning is performed to detect floods based on a convolutional neural network (CNN) model. The CNN model is validated ten times by training and testing it with randomly partitioned training and testing datasets, respectively. Initial results show that all validating models perform very close to each other. The best-trained model yields 80.67% accuracy, 86.33% precision, 81% recall, and 79.67% F1-score which shows satisfactory performance.
