Prediction of student’s academic performance during online learning based on regression in support vector machine

Since the Movement Control Order (MCO) was adopted, all the universities have implemented and modified the principle of online learning and teaching in consequence of Covid-19. This situation has relatively affected the students’ academic performance. Therefore, this paper employs the regression method in Support Vector Machine (SVM) to investigate the prediction of students’ academic performance in online learning during the Covid-19 pandemic. The data was collected from undergraduate students of the Department of Mathematics, Faculty of Science and Mathematics, Sultan Idris Education University (UPSI). Students’ Cumulative Grade Point Average (CGPA) during online learning indicates their academic performance. The algorithm of Support Vector Machine (SVM) as a machine learning was employed to construct a prediction model of students’ academic performance., Two parameters, namely C (cost) and epsilon of the Support Vector Machine (SVM) algorithm should be identified first prior to further analysis. The best parameter C (cost) and epsilon in SVM regression are 4 and 0.8. The parameters then were used for four kernels, i.e., radial basis function kernel, linear kernel, polynomial kernel, and sigmoid kernel. from the findings, the finest type of kernel is the radial basis function kernel, with the lowest support vector value and the lowest Root Mean Square Error (RMSE) which are 27 and 0.2557. Based on the research, the results show that the pattern of prediction of students’ academic performance is similar to the current CGPA. Therefore, Support Vector Machine regression can predict students’ academic performance

Effects of palm oil clinker as coarse aggregates replacement in self curing concrete

Concrete, if properly design, can be one of the most durable material and widely used in construction due to its availability and good compressive strength. A good quality concrete can be produced not only through good design of concrete mix proportions but also good and proper curing process that ensure a complete hydration process of the cement. However, sometimes proper curing process was not provided during concreting on site due to various reasons. This study investigates the effects of 10 mm crushed Palm Oil Clinker (POC) as partial aggregates replacement to act as internal reservoirs in concrete to provide internal curing process of cement. This process or technique is also popularly known as self-curing process for concrete. The POC which has the density of 780 kg/m3 was used to replace 20% of the coarse aggregates. A water/cement ratio of 0.53 was used in the concrete mix design. Three different curing conditions were employed, namely, normal water curing, air curing and 7 days in water plus outside curing conditions. The workability of the POC and control concretes was determined through slump test. The concrete samples were tested for compression at the age of 3, 7 and 28 days while concrete prisms and cylindrical samples were tested at the age of 7 and 28 days. The experimental results show that the inclusion of POC was found to increase the workability of concrete by 27% but reduced the concrete compressive strength by about 6% compared with the control concrete. In addition, the flexural and tensile strengths of POC concrete were found to be less than the control concrete due to the properties of the POC which was lightweight and porous. The experimental results show that the porous structure of the POC aggregates can be utilised as water reservoir for the process of internal curing for the self-curing concrete

Hearing impairment from the Islamic perspective: a review

Introduction: This discussion paper aims to synthesise available literature on hearing sciences from Islamic perspective and to relate this to the current hearing care practices. The paper focuses on several main scopes: i) the importance of sense of hearing from Islamic and scientific perspectives ii) impacts of hearing impairment iii) limitations in understanding and practicing Islamic teaching due to hearing impairment, iv) Islamic responsibility towards people with hearing impairment, v) current available methods to facilitate Islamic practices among hearing impaired people, and vi) incorporating Islamization in hearing care practice. Design: Narrative review and synthesis Method: Related publications and references were identified through several ways: i) by structured searches in PubMed, Google scholar, Web of Knowledge and Science Direct using the combinations of ‘Islam’, ‘hearing impairment’, ‘hearing loss’, ‘hearing’, ‘social’, learning’, ‘memory’, ‘disability’, ‘Islamic responsibility’, and ‘learning for deaf’ as key words, ii) by inspecting the reference lists of relevant articles, and iii) by identification of relevant references from Quran and Hadith by authors who have background in Quranic studies. Results: The number of publications within the audiology field, which address the aforementioned scopes, is rather limited. Additionally, a review and synthesis of literature from other related fields such as medical, health, and education, with references from Quran and Hadith, were also carried out to facilitate the discussion of the above mentioned scopes. Conclusion: This paper concludes that there is an emerging trend for the studies of hearing and Islam in the literature. Facilitating hearing impaired people in understanding and practicing Islam becomes a shared obligation for parents, society, and the patients themselves. This discussion also identifies that there is a need for more contributions from Muslim scholars in integrating and implementing the Islamic principles in current hearing care practices

Temperature sensing utilizing unclad plastic optical fiber with a balloon-like bent structure

A plastic optical fiber (POF) temperature sensor with high sensitivity is experimentally demonstrated in this work. The temperature sensor is realized by a combination of macrobending and an unclad region in the fabrication of its sensor head. The POF sensor is bent into a balloon-like structure in order to introduce the effect of macrobending. For the optimization of the sensor performance, the bending radius of the balloon-like structure is varied. Experimental results suggest that the performance is optimized when the bending radius is fixed at 55 mm.With this amount of bending radius, temperature sensitivity of up to 22.2x10-3°C-1 can be achieved in the range from 40°C to 80°C, with linearity of 0.99 and resolution of 0.45°C. This technique is found to improve the POF temperature sensitivity in comparison to previous developments

Ammonia detection in water with balloon-like plastic optical fiber sensor

This work presents the demonstration of a plastic optical fiber(POF)-based ammonia sensor. The sensor head is formed by bending an unclad fiber optic sensor into a balloon-like structure. The bending radius of the balloon-like bent fiber optic sensor is varied from 1.0 to 2.5 cm. The performance of each sensor is tested using ammonia solution with concentration ranging from 0 to 15 mg l−1 . Results show that the optimized performances of the proposed sensor occur when the bending radius is fixed at 1.5 cm. At this bending radius, the sensor illustrates the sensitivity of − 0.0024 (mg/l) −1with linearity of 0.97 and resolution of − 4.17 mg l−1 . For comparison, the bent sensor is compared to the straight sensor and performances of the former is found to be more superior. In addition, the balloon-like bent sensor is further tested with real water samples. The sensor sensitivity is found to be − 0.0022 (mg/l) −1with linearity of 0.95 and resolution of − 4.54 mg l−1 . The result shows that the sensor has comparable performance in the ammonia detection for both pure ammonia and real water samples. In essence, this balloon-like bent sensor functions without additional coating on the sensor head, making it favorable in terms of the simplicity of the design

The Malaysian Acute Vascular Events Risk (MAVERIK) study protocol: studying genetic and other determinants of first-ever myocardial infarction in Malaysia (Preprint)

INTRODUCTION: Although the burden of premature myocardial infarction (MI) is high in Malaysia, direct evidence on the determinants of MI in this multi-ethnic population remains sparse. The Malaysian Acute Vascular Events Risk (MAVERIK) study is a retrospective case-control study established to enable investigation of genomic, lipid-related and other determinants of acute MI in Malaysia. To our knowledge, it represents the largest case-control study of MI and related traits in Malaysia. In this paper, we report the study’s design and initial results. METHODS: By June 2019, MAVERIK had enrolled about 2500 patients with first-ever MI and 2500 controls without cardiovascular disease (CVD), frequency-matched by age, sex and ethnicity, from 17 hospitals in Malaysia. For each participant, serum and whole blood have been collected and stored. Clinical, demographic and behavioural information has been obtained using a 200-item questionnaire. RESULTS: Tobacco consumption, history of diabetes, hypertension, markers of visceral adiposity, indicators of lower socioeconomic status, and family history of coronary disease were more prevalent in cases than controls. Crude and adjusted (age, sex) logistic regression models for traditional risk factors indicated that current smoking, previous smoking, history of high blood pressure, history of diabetes mellitus, family history of CHD and obesity (BMI>30) were associated with MI in age- and sex-adjusted models. CONCLUSION: The MAVERIK study can serve as a useful platform to investigate genetic and other risk factors for MI in an under-studied South-East Asian population. It should help to hasten discovery of disease-causing pathways and to inform regionally appropriate strategies that optimise public health action

Investigating Genetic and Other Determinants of First-Onset Myocardial Infarction in Malaysia:Protocol for the Malaysian Acute Vascular Events Risk Study

BACKGROUND: Although the burden of premature myocardial infarction (MI) is high in Malaysia, direct evidence on the determinants of MI in this multi-ethnic population remains sparse. OBJECTIVE: The Malaysian Acute Vascular Events Risk (MAVERIK) study is a retrospective case-control study established to investigate the genomic, lipid-related, and other determinants of acute MI in Malaysia. In this paper, we report the study protocol and early results. METHODS: By June 2019, we had enrolled approximately 2500 patients with their first MI and 2500 controls without cardiovascular disease, who were frequency-matched by age, sex, and ethnicity, from 17 hospitals in Malaysia. For each participant, serum and whole blood have been collected and stored. Clinical, demographic, and behavioral information has been obtained using a 200-item questionnaire. RESULTS: Tobacco consumption, a history of diabetes, hypertension, markers of visceral adiposity, indicators of lower socioeconomic status, and a family history of coronary disease were more prevalent in cases than in controls. Adjusted (age and sex) logistic regression models for traditional risk factors indicated that current smoking (odds ratio [OR] 4.11, 95% CI 3.56-4.75; P30 kg/m(2); OR 1.19, 95% CI 1.05-1.34; P=.009) were associated with MI in age- and sex-adjusted models. CONCLUSIONS: The MAVERIK study can serve as a useful platform to investigate genetic and other risk factors for MI in an understudied Southeast Asian population. It should help to hasten the discovery of disease-causing pathways and inform regionally appropriate strategies that optimize public health action.

Prospective observational cohort study on grading the severity of postoperative complications in global surgery research

Background The Clavien–Dindo classification is perhaps the most widely used approach for reporting postoperative complications in clinical trials. This system classifies complication severity by the treatment provided. However, it is unclear whether the Clavien–Dindo system can be used internationally in studies across differing healthcare systems in high- (HICs) and low- and middle-income countries (LMICs). Methods This was a secondary analysis of the International Surgical Outcomes Study (ISOS), a prospective observational cohort study of elective surgery in adults. Data collection occurred over a 7-day period. Severity of complications was graded using Clavien–Dindo and the simpler ISOS grading (mild, moderate or severe, based on guided investigator judgement). Severity grading was compared using the intraclass correlation coefficient (ICC). Data are presented as frequencies and ICC values (with 95 per cent c.i.). The analysis was stratified by income status of the country, comparing HICs with LMICs. Results A total of 44 814 patients were recruited from 474 hospitals in 27 countries (19 HICs and 8 LMICs). Some 7508 patients (16·8 per cent) experienced at least one postoperative complication, equivalent to 11 664 complications in total. Using the ISOS classification, 5504 of 11 664 complications (47·2 per cent) were graded as mild, 4244 (36·4 per cent) as moderate and 1916 (16·4 per cent) as severe. Using Clavien–Dindo, 6781 of 11 664 complications (58·1 per cent) were graded as I or II, 1740 (14·9 per cent) as III, 2408 (20·6 per cent) as IV and 735 (6·3 per cent) as V. Agreement between classification systems was poor overall (ICC 0·41, 95 per cent c.i. 0·20 to 0·55), and in LMICs (ICC 0·23, 0·05 to 0·38) and HICs (ICC 0·46, 0·25 to 0·59). Conclusion Caution is recommended when using a treatment approach to grade complications in global surgery studies, as this may introduce bias unintentionally
