Hydroelectric energy remains one of the most vital renewable energy sources worldwide as it contributes to more than 16% of the global electricity generation. The study investigates the impact of varying the masses of sandstone, basalt, and limestone on reducing the energy, CO2 footprint, and overall costs of the system. Additionally, 6 different alternatives with varying masses of sandstone, basalt, and limestone were investigated. In this study, alternative 5 involved increasing the mass of limestone and decreasing the mass of the basalt. It was found that this resulted in the lowest CO2 footprint and total energy. Furthermore, alternative 2 involved increasing the mass of sandstone and decreasing the mass of the basalt. The study results show that alternative 2 was found to yield the lowest cost; however, it was relatively close to the cost found in alternative 5. In order to further reduce the CO2 footprint and total energy of the system, end-of-life (EOL) was investigated for alternative 5. The EOL potential successfully reduced the total energy and CO2 footprint by 3.1 MJ and 203 tonnes, respectively.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"7 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74515806","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 binder was activated using alkaline solution consisting of combination of Na2SiO3 and NaOH. One set of mortar samples was cured by exposure to normal air at a temperature of 22±2 0C and 70% RH, and another set was cured under 10% sulfuric acid solution, in order to quantity its effect on compressive strength development. Water-cured mortar samples exhibited higher compressive strength at the age of 28-days in contrast with air-cured samples. The highest compressive strength at the age of 28-day was developed by mortar samples with binders consisting of GGBS: fly ash ratio of 3:1, compared to binders with equal amounts of fly ash and GGBS, as well GGBS as sole binder. This was consistent for NaOH concentration of 10M, 12M, and 14M. A 2nd degree polynomial was found to strongly correlate splitting tensile strength to 28-day compressive strength of air-cured mortar samples. The correlation weakens with the addition of 25% fly ash, and diminishes when fly ash is 50% of the binder content.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"52 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78693675","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}

As for Physics which is a crucial component required for any engineering programme, it weaves algebra and mathematical equations extensively into its instruction and delivery. However, the course content and assessments are often delivered using a language, for example English in the case of this study, as a medium of instruction. In this study we aim to investigate the effect of language simplification on international students’ test performance in Physics. Students on an International Foundation Programme in Science and Engineering at a higher education institution (HEI) were given standard assessments, as well as parallel assessments with reduced linguistic complexity. Statistical analysis of the results reveal that the linguistic modification of test items resulted in significant improvement in Physics performance; student scores on the linguistically modified version were significantly higher. Some student groups benefited more from the linguistic modification of items - in particular, students who were originally low-performing.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"43 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80044488","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}

Machine Learning techniques have been implemented to assess the performance of such industries and further improve the allocation of their resources. Many measures of performance exist to infer how a healthcare facility uses its resources. Readmission rate is a very popular rate in analyzing the performance of a healthcare facility. In this paper, we assess the readmission rate of a Sharjah healthcare facility in the first ten months of 2021. We have used classification techniques such as Logistic Regression, Random Forests, Neural Networks, and Gradient Boosting to find the best prediction model. We then used logistic regression to infer the relationships between the most important variables and the readmission rate. Results showed that the readmission rate was most influenced by the hospital departments, insurance type, marital status, age, and diastolic blood pressure. Relationships of such variables are outlined in the paper and can be further investigated to reduce readmission rates for cost reduction.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"39 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80125549","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 they are commonly found in various constructed settings and pavements, their traction properties have not been methodically explored to prevent pedestrian fall incidents. This pilot study examines the effect of different surface textures of concrete slabs on slip resistance functioning and identifies their roles on fall safety controls. For the concrete slabs, the three most commonly applied methods: metal blade trowelling, worn wood blade trowelling, and bloomswept, were used to generate different surface finishes. Dynamic friction tests were performed amongst three concrete slabs and three new shoes under four disparate environments: dry, wet, soapy, and oily. Test results show that a strong effect of the surface finishes of the concrete slabs was found on dynamic friction coefficients (DFCs) under soapy and oily environments. The current study also uncovered that rough concrete slabs did not reflexively support higher slip resistance performance under lubricated environments. Those findings identify imperative evidence on tribological characteristics of the concrete slabs and their impacts on traction properties. It is hoped that this study may have possible appliances for design improvement of concrete surfaces to prevent pedestrian fall incidence.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"55 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85642933","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}
