Researchers in related fields have made numerous attempts to solve the problem that the model's parameter identification method is complex and difficult to implement. A method combining nonlinear least square method is proposed to identify the parameters of the Bouc-Wen model of magnetorheological damper based on the damping characteristics test. Analyze the relationship between the identification parameters and the current and use the curve fitting toolbox to fit the functional relationship. At the same time, use the Simulink toolbox to create a Bouc-Wen simulation model of a magnetorheological damper and select sinusoidal signals with varying current, amplitude, and frequency for simulation and comparison. The Bouc-Wen model is validated using additional amplitude and frequency test data, and the results show a high degree of fit between the test and simulation results. This method can effectively identify the dynamic model's parameters.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80008756","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}

Abiotic surfaces include floors, walls, drains, equipment, and food-contact surfaces, as well as biotic surfaces like meat, the oral cavity, the intestine, the urogenital tract, and the skin. Humans are a good source of biotic microenvironments for biofilm and bacterial growth, which leads to infectious diseases in most cases. The optimum biotic environment for bacteria to thrive requires a supply of nutrients, humidity, and the right temperature. Biofilms originate on inert surfaces or dead tissue, and they're frequent on medical devices and dead tissue fragments, but they can also form on living tissues. Biofilms' tolerance to harsh environments provides a favorable habitat for microbial populations, allowing for a more efficient flow of chemicals and information amongst microorganisms. As a result, biofilm resistance is a self-protective strategy for microbial development. Bacterial biofilms are detectable by direct and indirect methods and they could be controlled. Bacterial biofilm is a major cause of antimicrobial-resistant bacteria's development and spread, causing severe infections and increased mortality rates.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81935326","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 current study analyzes Madrasa students’ English writing errors. The students were grouped into an experimental group (EG) and control group (CG) and engaged for twenty-eight days, where only EG learners received blended learning (BL) treatment. The investigation used a pre-and post-test purposive design across all the groups. The errors were spotted from their write-ups belonging to morphological, syntactical, and orthographical categories. Next, errors were analyzed both quantitatively and qualitatively. Though the results revealed that both groups committed errors in all seven categories: morphological (article and preposition), syntactical (tense and word order), and orthographic (capitalization, spelling, and punctuation) types, EG’s errors were fewer than CG’s. This implies that BL can lead to effective remedial writing in Madrasa classrooms. In addition, EG’s pre-test scores were also greater than post-test scores, which has implications for adopting BL at different Madaris in India.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89409063","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}

About 30 to 40 percent of the total heat delivered to the engine in the form of fuel is transformed into meaningful mechanical work. It is necessary to convert waste heat into usable work since the leftover heat is released into the environment through exhaust gases and engine cooling systems, leading to an increase in entropy and major environmental degradation. Due to the specific advantages of thermoelectric generators, they have emerged as a possible alternative green technology as waste heat recovering techniques like the thermoelectric generator (TEG) are developed. A techniquethat can directly convert the thermal energy found in exhaust gas into electric power is the subject of the majority of current study. In this research, a thermoelectric power generator based on exhaust gas was developed for industrial use. The exhaust gases in the pipe serve as the thermoelectric power generator's heat source. As a result, this study suggests and puts into practice a thermoelectric waste heat energy recovery system using the exhaust heat from running equipment. The goal of the project is to directly transform the heat energy from vehicle waste heat to electrical energy using a thermoelectric generator. Although the largest amount of electric power produced by such a system is just 10 W from a single TEG module, significant advancements in material science can make the ambitious aim of generating larger wattages by any means a real possibility.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80614760","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 study employs morphometric analysis, which includes area, perimeter, mean stream length, drainage density, stream frequency, and basin length, as well as other factors like elongation ratio, form factor, shape factor, relief ratio, and density, with the assistance of the Shuttle radar topography mission (SRTM) and ArcGIS software. The Ekole River has an area of 83.76 km2 and a perimeter of 100.75 km, according to the findings. The average stream length was 0.41 km, and the average bifurcation ratio was 2.15. The drainage density was 2.28 km/km2 and the stream frequency was 5.56. The elogation ratio, form factor, shape factor, and relief ratio were also determined to be 0.20, 0.32 km/km, 3.14, and 3.11, respectively. These findings reveal that the Ekole River has a comparatively low discharge density and a dendritic drainage structure. The elongation ratio, form factor, and relief ratio, on the other hand, indicate that the basin of the river is comparatively elongated and narrow, with low relief. The present condition of the Ekole River is thought to be the result of climate change, which has impacted the river's hydrological processes. Finally, this research sheds light on the effects of climate change on the Ekole River and its morphometric features. Climate change has changed the river's hydrological processes and affected its morphometric parameters, according to the results.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90655580","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}

Recovery and separation of rare earth elements are particularly crucial due to the steadily rising demand, as they can enhance scarce resources and reduce radiation-related waste disposal harm. Reports about the harmful effects of rare earth elements on microbes, plants, and animals have become increasingly common in recent years. More dangerously, residues from rare earth elements can build up in the human body through ingestion or digestion in the food chain. Finding a practical and affordable way to use rare earth elements or remove them from our surroundings is therefore essential. To extract these elements, halloysite is processed using a straightforward chemical procedure to produce rare earth metal ion adsorbent materials. The Halloysite that has been processed has a rod-shaped, one-dimensional nanomorphology. Halloysite-kaolinite is the two-phase version of the adsorbent material. The strong adsorption capacity of halloysite for Ce3+ is demonstrated by research findings. Halloysite adsorbs Ce3+ using the monolayer physical adsorption model and the pseudo-second-order adsorption kinetic equation.","PeriodicalId":13758,"journal":{"name":"International Journal of Advanced Engineering Research and Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135758585","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}
