Accordingly, as a result of the variance analysis applied to the data of the percentage of survival variable, which is important in terms of adaptation ability, it was determined that there was a statistically significant difference at the P˂0.05 confidence level in terms of afforestation areas. In this respect, as a result of Duncan test performed at P˂0.05 confidence level to create homogeneous groups, Ulukonak oak plantation area established with Q. infectoria with a survival rate of 89% is in the first group, and this group is classified with a survival percentage of 78%. Celaliye plantation area established with Q. cerris species followed. In the study, mean values were determined in terms of afforestation areas regarding the quantitative and morphological characters determined in the trial areas taken from the oak afforestation areas. When these data are examined, the mean diameter value varies between 2.3-5.1 cm in Q. petraea afforestation areas of different ages, 2.0-3.6 cm in Q. infectoria afforestation areas, 3.5 cm in Q. frainetto and Q. cerris.

The used system is based on a series–series (SS) compensated circuit via flat spiral coils. Moreover, the recommended approach system finds optimum capacitor values for the best efficiency point where the RIC-WPT system operates. Flat spiral three-dimensional (3D) coils are modelled and parametric analysed with different air gaps in ANSYS-Electronics-Maxwell software which is based on the Finite Element Method (FEM). Then power electronics circuit with a full-bridge inverter is designed in Ansys/Simplorer software. The coils and the power electronics circuit are co-simulated with parametric values. Thus, as a result of parametric simulation studies, the most efficient version of a Wireless Power Transfer (WPT) system structure is proposed with the design and normalized power electronics elements that can be physically applied for the chosen operating frequency value. As a result of the simulation studies, power transmission is realized with an efficiency of approximately 74.31% while the distance between the coils was 200 mm. Furthermore, useful information for WPT designs is been obtained thanks to co-simulation studies by changing power electronics circuit parameters and electromagnetic modelling parameters.","PeriodicalId":197560,"journal":{"name":"Kastamonu University Journal of Engineering and Sciences","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121782908","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}

As a result of the increasing destruction of the ozone layer caused by anthropogenic sources, the effect of harmful sun rays reaching our world is increasing. It is estimated that the temperatures on the earth's surface and ultraviolet-B (UV-B) radiation will increase in the coming years due to global climate change. This study used ash-leaved maple (Acer negundo) and sycamore maple (Acer pseudoplatanus) seedlings to examine the effects of drought and UV-B radiation levels that may occur in the coming years on forest trees. The study investigated the effect on stomatal characters by applying two different doses of UV-B and drought stress. As a result of the study, it was determined that UV-B stress had a more significant effect on stomatal characters than drought stress. It has been observed that severe drought generally reduces the number of stomata. It was determined that the sycamore maple was more affected by severe drought and UV-B radiation. While UV-B radiation decreased only the stomatal pore length and width in sycamore maple, it increased the stomatal pore length and width in ash-leaved maple. The response of stomatal characters to drought and UV-B stress remains unclear. Therefore, more detailed studies are required.","PeriodicalId":197560,"journal":{"name":"Kastamonu University Journal of Engineering and Sciences","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127831936","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}

Thus, the estimation process of the electromagnetic modelling of the transformer has been successfully carried out thanks to the training and testing processes of Adaptive Network Based Fuzzy Inference Systems (ANFIS) with the numerical information obtained from the finite element analysis (FEA) parametric data set. After the estimation processes, the percentage error is calculated as 0.3470% and 0.4448% for training and testing. Thus, the determination of the isolation transformer with the optimum values designed for the inverter circuit has become easier. Also, experimental analysis is performed on inverters to prove the robustness of the proposed method. In this context, first of all, RMS values that vary according to the different operating parameters of the inverters are created.
