In order to determine the fuel that generates the least amount of carbon dioxide and is cost-effective, various types of traditional marine fuels and those that are yet to be introduced into operation have been considered. The advantages and disadvantages of bunkering, transporting, and storing various types of alternative marine fuels have been defined. The analysis shows that the lowest carbon dioxide emissions are generated when using alternative biofuels such as methanol and methane. Furthermore, if HVO fuel, which has not yet gained widespread use in shipping, is employed, emissions will be reduced by approximately 90%. From an economic perspective, methane and methanol have the lowest cost per ton of fuel compared to HVO, which is about four times higher in comparison to methane and methanol. Considering the IMO regulations for reducing harmful emissions into the atmosphere, HVO appears to be the future fuel that will normalize its prices.","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"43 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158850","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}

Experimental investigation has been conducted on annealed and tempered steel according to the planning methodology (L8). The input parameters are cutting regime elements (cutting speed, feed rate and drill diameter) and the output parameter is the tool wear related to tool life. Beyond, the common behavior that suggests that when the feed rate on tool life increases the tool life increases, the most interesting phenomenon is the controversial effect of the cutting speed when drilling the steel in tempered condition.

In order to eliminate this situation, some antenna technologies have been developed and started to be used in smart devices. The smart phones, which were developed by adhering to the DRx (Diversity Receive) design scheme, best perceived the signals emitted from the base station, thus increasing the Rx performance of the developed products. Typical integrated (total) surface metrics include Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS). TIS and TRP metrics have become increasingly important for carriers, because a TRP measurements used to verify your transmitter or transmitter antenna design. A TIS measurement used to verify how your receiver or receiver antenna design performs. In this study, we aimed to determine the Rx performance of the DRx scheme used in smartphones by using 3D radiation test setup (TIS - Total Isotropic Sensitivity).","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139159535","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}

To evaluate this impact, the current research aimed to investigate the relationship between information systems (IS) success factors, decision-making quality (DMQ), and organizational performance (OP). A quantitative research approach was adopted, and a survey was sent to 163 decision-makers who use information systems in business firms. The study model was evaluated using PLS-SEM. The study's empirical results indicated that information quality (IQ) significantly positively impacted decision-making quality (DMQ). However, system quality (SQ) did not affect decision-making quality (DMQ). Furthermore, information quality (IQ) was found to mediate the relationship between system quality (SQ) and organizational performance (OP). Finally, the decision-making quality (DMQ) was found to moderate the relationship between information quality (IQ), system quality (SQ), and organizational performance (OP).

Bobbin tool friction stir processing (BTFSP) is a novel version of conventional FSP. In the present paper, 6 mm thick plates of Al-Mg-Si (6061Al –T6) were subjected to BTFSP and CFSP using B4C reinforcement particles for comparison. The reinforcement particle distribution and mechanical properties were investigated in the fabricated composites. Agglomeration was observed in BTFSP composites. The crack formation in the BTFSP was due to the absence of forging action, which deposited the B4C particles in the crack. CFSP composites obtained uniform distribution of the B4C particles at the top surface. The tilt of the tool in CFSP helped in effective forging action by the shoulder at the trailing edge. Micro-hardness results indicated improved hardness at the top surface for both the processed composites.","PeriodicalId":22384,"journal":{"name":"The Eurasia Proceedings of Science Technology Engineering and Mathematics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136113506","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}
