Typically, MOSFETs are wired in parallel for applications that require high power. Theoretically, this circuit can multiply the current capability of parallel MOSFETs. However, even if all the MOSFETs in a parallel circuit have the same serial number and manufacturer, they might not necessarily have the same current characteristics. This could lead to issues with current imbalances, potentially causing harm to the MOSFETs, especially under severe circumstances. This study introduces a new Active Gate Driver (AGD) technique to balance the current in a parallel MOSFET circuit. The current difference can be used to modulate each MOSFET duty cycle. Specifically, the MOSFET with the smallest current capacity is configured as the Master, while the MOSFET following it is designated as the Slave. The interrupt time value for the duty cycle of each Slave MOSFET is influenced by the current differential between the Master and Slave. Consequently, different duty cycles for the Master and Slave MOSFETs can maintain the same current level. Based on the results of experiments conducted on three MOSFETs, it is evident that the AGD approach can effectively balance the current to an optimum level.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691575","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 method comprises computation of shortest path of both, static and dynamic IoT (Internet of Things) network using “widely used algorithms” among researchers, namely, ‘Breadth first search’ and ‘Dijkstra algorithm.’ Further, the determined route has been optimized using ant colony optimization. The issue of route selection to reach the destination, as well as parameters such as network energy, departed node count, residual energy of IoT nodes, and critical points of IoT nodes have been explored using proposed smart routing techniques. The two unique routing approaches have been simulated with rigorous iteration run, i=2000. The proposed methods, ‘Ant colony optimization-Breadth first computation-Minkowski-Static’ (ABMS) technique and ‘Ant colony optimization-Breadth first computation-Minkowski-Dynamic’ (ABMD) technique have been simulated. After comparing efficiency between both techniques, ABMS method outperforms the ABMD routing technique for IoT network. A significant energy savings has been reported, extending network lifetime of a static IoT network scenario. With the implementation of both techniques, the comparison between dynamic and static results closely.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44349340","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 effect of nano fluid and (base) fluid flowing inside rectangular micro channel with or without insert were acknowledge, for analysis the behavior of fluid flow, heat transfer and performance characteristics like Nusselt number (Nu), Friction factor (f), Effectiveness (Ɛ), Coefficient of thermal transfer (h), Heat transfer factor (Q), Nu/Nus, f/fs, thermal-performance factor (TPF), Number of transferring unit (NTU) and Reynolds’s number (Re). During preparation of nano fluid 0.01% volume fraction, 10-20 nm size nano particles were taken with 0.5ml CTAB (cetyl-2 tri-methyl, ammonium-bromide) surfactant. Experimentation was conducted for different operating parameters under counter flow conditions, where nano fluid is flowing inside micro channel of 0.081mm diameter with flow rate 0.0001562 kg/sec (9.37 ml/min) to 0.006255 Kg/sec (375.30 ml/min) and hot water is flowing inside the concentric tube of 3cm diameter with flow rate of 0.000782 Kg/sec (46.92 ml/min). The operating temperature of nano fluid and hot water were 303K and 323K. As per obtained results, the proposed composition of nanofluid showed better performance than base fluid due to better thermal conductivity and extra molecular area gain in nanofluid due to addition of nano particle with base fluid. It improves the results 21% approximately. Better optimum results were observed in case of rectangular micro channel with micro insert compared with other geometry because of rich turbulency gain and extra exposed area due to micro insert. It affects optimum results in terms of better performance up to 9%-18% compared with simple micro channel without inserts.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42047120","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}

Until now, no cure for COVID-19 has been found and the efforts made are vaccine distribution, so it is necessary to increase daily human immunity. M pro SARS-CoV-2 is an enzyme for viral replication in host cells so that it can be a target of inhibition. In this study, an in-silico simulation of flavonoid compounds in green meniran plants was carried out: Astragalin, Isoquercitrin, Quercitrin, and Rutin with Quercetin as a control ligand. Predictive analysis of ADMET properties showed that all ligands showed good safety for drug use in humans, except Rutin. The four ligands showed good scores on molecular docking results, which had lower binding scores and MM-GBSA than Quercetin. Molecular dynamics simulation for 20 ns showed that all ligands had good interaction stability, and Quercetin and Isoquercitrin tended to have the most stable interaction. Overall, it was found that Isoquercitrin showed better potential as a M pro SARS-CoV-2 inhibitor with a binding score of -11.973 kcal/mol , an average RMSD of 1.652Å, the highest RMSF value of 2.12Å, interacted with 25 protein residues, and had 12 torsions with strain energy of 0.748 kcal/mol .","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46340335","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}
