Early diagnosis of this condition lessens the patient's repercussions. The paper gives a thorough overview of the disease, its classifications, algorithms, and methods employed emphasizing the challenges encountered in this field. Traditional methods of diagnosing cardiomegaly rely on medical imaging techniques such as echocardiography or chest X-rays, which can be time-consuming and require specialized expertise to interpret. However, recent advances in deep learning algorithms have shown promise in accurately identifying cardiomegaly and its underlying causes from medical images. The use of deep learning algorithms in the diagnosis of cardiomegaly has the potential to improve both the speed and accuracy of diagnosis, leading to better patient outcomes and more efficient use of healthcare resources. Moreover, deep learning algorithms can potentially identify subtle changes in heart size over time, allowing for earlier detection and treatment of cardiomegaly.","PeriodicalId":115908,"journal":{"name":"Journal of Kufa for Mathematics and Computer","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115737656","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}

Universities were therefore obliged to move from traditional education to e-education without adequate preparations. The aim of this research is to analyze the students' performance in the two educational environments and predict the result of any of them in the future. The k-means algorithm, an important data mining method, was used to analyze the results of the fourth-stage classes of five consecutive years of students from one Iraqi university's scientific departments. Four of these years were traditional education, while the last was E-education to see whether the student's performance distribution is normal or abnormal. The results indicate a 100 percent of students’ success rate in e-education, while the upper limit is 70 percent for the previous years. \u0000Moreover, the average class rate increased to 75 percent compared to 62 in previous years.  The decision tree has been built based on a dataset created from the collected data to predict the distribution of both traditional and e-education with a 2% error tolerance. The study shows that using the exact mechanism in e-education will give abnormal results. Therefore, the study recommends the need for good infrastructure, the preparation of efficient staff, increasing students’ skills, and appropriate software platforms for an accurate assessment of students’ performance.","PeriodicalId":115908,"journal":{"name":"Journal of Kufa for Mathematics and Computer","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121427135","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}
