In order to predict the Ordinal Logistic Regression Model, it must provide the parallel lines assumption. In the study, the happiness levels of divorced individuals were estimated with the ordinal logistic regression model. The data set used in the analysis was obtained from the Life Satisfaction Survey implemented by the Turkish Statistical Institute in 2020. Brant's Wald Test and Likelihood Ratio Test were applied for the parallel lines assumption and the null hypothesis could not be rejected. In this context, the model ordinal logistic regression model was estimated. \u0000The statistically significant gender variable shows that divorced women are happier than divorced men. It has been determined that success and job variables tend to decrease happiness levels in divorced individuals compared to other factors. In general, when the education level is examined, it is seen that the level of happiness of divorced individuals increases as the education level increases. It has been concluded that divorced individuals who are satisfied with their health, education, income and social life are happier than divorced individuals who are not satisfied with their health, education, income and social life. It has been determined that divorced individuals are registered with the Social Security Institution and their happiness levels are higher than those who are not registered.","PeriodicalId":102219,"journal":{"name":"MANAS Journal of Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117092112","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 limited use of brushed models in some areas has made Brushless Direct Current Motors stand out. In this paper, the design and analysis of an efficient, high power density, brushless direct current motor (BLDC) for use in electric vehicles is carried out. In this direction, studies have been carried out to reduce the reverse induced voltage, which is the biggest problem of electric motors in the electric vehicle sector. Analyzes were carried out with ANSYS subprograms, which realized a Finite Element Method (FEM) based solution to change the nominal values of the BLDC motor by changing the distance between the rotor and the stator. According to the results of the analysis, it was concluded that the method used in the study can also be used in high speed applications of brushless direct current motors.","PeriodicalId":102219,"journal":{"name":"MANAS Journal of Engineering","volume":"282 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114048835","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 characterization of Fe 3 O 4 /NiMn-LDH were recognized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Box-Behnken design (BBD) under response surface methodology (RSM) were applied to evaluate the effects of the process variables such as pH, adsorbent dosage, and initial PR concentration (C o ). The results indicated that a good correlation between the estimated and experimental values was found for the PR decolorization efficiency from aqueous media using Fe 3 O 4 /NiMn-LDH ( R 2 = 0.99). Furthermore, the statistical model obtained from BBD was sufficient to estimate the PR decolorization on Fe 3 O 4 /NiMn-LDH ( p < 0.0001). The optimal conditions for the PR decolorization efficiency were determined as 5.38, 24.59 mg, and 25.39 mg/L for pH, adsorbent dosage, and C o , respectively which resulted in 86.93% the PR decolorization efficiency. Finally, this work demonstrated that BBD could easefully be utilized for the optimization of the PR decolorization using Fe 3 O 4 /NiMn-LDH.","PeriodicalId":102219,"journal":{"name":"MANAS Journal of Engineering","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114413682","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}
