However, high costs, quality assurance and long machining times are inevitable challenges in ultraprecision manufacturing. This scientific talk presents the concept of a virtual lens model based on the requirement of ‘deterministic manufacturing’ in the ultraprecision machining process, while enabled by scientific understanding of micro cutting mechanics and its applicational affect. By analysis of the freeform surface modelling and machining toolpaths and underlying micro cutting mechanics, this research aims to define surface quality and its optical performance prior to the machining process. The research further delves into cutting force modelling and 3D surface parameters to analyze the machining toolpath, and virtual simulations and experiments are conducted. The simulations and experiments are focused on verifying the correlations between the surface characteristics, such as surface roughness, peak valley distance and most importantly, surface texture aspect ratio, and the optical performance of the freeform surface. The analysis of surface texture formation and cutting forces modelling are essential for the simulation development and experimental design. The cutting forces modelling integrates the Akins' model with the influence of continuously varying shear angles on the freeform surface. Toolpath data from the cutting process is used to meticulously analyze depth-of-cut (DoC), curvature variations, and shear angle variations throughout the process, and thus to enable the consistent surface texture aspect ratio at the surface generation as desired.</p></div>","PeriodicalId":101148,"journal":{"name":"Science Talks","volume":"12 ","pages":"Article 100392"},"PeriodicalIF":0.0,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772569324001002/pdfft?md5=c777a3deaf95a36898aafdec588eba8d&pid=1-s2.0-S2772569324001002-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From this angle, the current study aims to assess the impact of environmentally friendly and renewable gasoline additives on generating low-carbon high-octane gasoline biofuel using multiple renewable and sustainable additives. Renewable and sustainable gasoline biofuel additives include ethanol, methanol, ethyl tertiary butyl ether (ETBE), isopropanol, and so on, which have exceptional anti-detonation properties and excellent chemical and physical characteristics. Furthermore, the base commercial gasoline components involve straight-run naphtha (SRN), naphtha made from natural gas condensate, heavy hydrocracked naphtha (HHN), gasoline Fisher Tropsch, and so on, which have poor chemical and physical attributes and low octane rating. Physicochemical characteristics and operational properties of various gasoline biofuel components are studied. Research findings indicated that these encouraging constituents have yielded favorable synergistic chemical, physical, mechanical, and environmental properties when combined with low-octane hydrocarbon fractions. Besides, the results reported that by combining with gasoline components to create high-octane gasoline, the amount and quality of low-octane gasoline fractions were optimized. The primary issues that affect the entire planet are the scarcity of water, energy, and the environment. Two of the above energy and environmental issues might be resolved by utilizing these motor gasoline components. Finally, environmental gasoline offers refining firms favorable prospects due to its low overhead, improved product grade, and significant environmental impact.</p></div>","PeriodicalId":101148,"journal":{"name":"Science Talks","volume":"11 ","pages":"Article 100389"},"PeriodicalIF":0.0,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772569324000975/pdfft?md5=f3788ae1212ea5cc00cf528bd323d860&pid=1-s2.0-S2772569324000975-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142048334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods used to measure poverty today are costly, labor-intensive, and time-consuming. Therefore, policymakers find it difficult to target policies when putting poverty reduction initiatives into action. Indigenous communities are among the most disadvantaged and vulnerable populations in society. Their socioeconomic situations are complex and multifaceted. While research on poverty is usually generic, prone to large sampling errors, and intended to guide national policy, research on indigenous people is qualitative. Thus, to measure multidimensional poverty with disaggregated techniques, this work blends machine learning and econometrics. Researchers who have been studying poverty worldwide can replicate all of the approaches, strategies, and resources used in this study. With the best R-square and accuracy, random forest models perform better than all regressors and classifiers combined. It also confirms the causal relationship and current econometric association between multidimensional characteristics and poverty consequences. This study demonstrates the viability of using machine learning to predict poverty in a way that can save costs, cut labor, and maximize time to empower indigenous communities and alleviate the poverty of impoverished societies in the poorest region of Luzon, Philippines.</p></div>","PeriodicalId":101148,"journal":{"name":"Science Talks","volume":"11 ","pages":"Article 100387"},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772569324000951/pdfft?md5=99506727c503045e67227941dcd1e243&pid=1-s2.0-S2772569324000951-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141852144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laser pulses at 266 nm of fluence below the ablation threshold were used to oxidize the surface and remove carbon, through 2-photon-induced photo-chemical ejection, and the effects on the electrical and chemical surface properties were measured. It is found that the resistance of a hydrogen surface increases with the UV dose from 2 to 3 kΩ up to the measurement limit of 100 GΩ for doses corresponding to 0.5 monolayers, behaviour which agrees well with geometric and tunneling percolation arguments for the surface conduction. We also show that dosing before hydrogenation produced up to five times reduction in surface resistance and an increase in carrier concentration, and that these effects enable enhancement of the current density of diamond surface field effect transistors. We use XPS measurements of the surface chemistry as a function of dose to help elucidate the UV-induced mechanism responsible for enhancement.</p></div>","PeriodicalId":101148,"journal":{"name":"Science Talks","volume":"11 ","pages":"Article 100386"},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277256932400094X/pdfft?md5=a9fb9f5dfde69568969d1c6cc0014fc7&pid=1-s2.0-S277256932400094X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141849100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
