These effects will differ in different regions due to their topographic structure, location, and orographic characteristics. Trend analyzes are used to determine the direction and magnitude of this variability. In this study, trend analysis was carried out by using hydrometeorological data obtained from streamflow and meteorology stations located in the Karasu Sub-Basin located in the Euphrates-Tigris Basin. Three innovative trend methods, namely the Şen-Innovative Trend Analysis, Onyutha Trend Test, Combination of Wilcoxon Test and Scatter Diagram trend tests, were used together with the classical Mann-Kendall method in the monthly scale analysis of hydrometeorological data of the 1979-2020 period. Both graphical and statistical trend analysis can be done with innovative methods. The results obtained in the study, in which trend analyses were evaluated at the α=0.05 significance level, reveal significant and insignificant decreasing trends in the parameters of mean streamflow, maximum precipitation, total precipitation, mean and minimum relative humidity. Significant and insignificant increasing trends were determined in the maximum, minimum, and mean temperature, maximum relative humidity, and mean wind speed data. The trends obtained in the methods used in general are consistent with each other. The findings of this study could lead to a better knowledge of the region's hydrology and contribute sustainable water management. The trend analysis methods used in the study are thought to be quite helpful in the analysis of hydro-meteorological time series.","PeriodicalId":17899,"journal":{"name":"Konya Journal of Engineering Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73423435","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}

Kırıkkale ilinde YHT istasyonunun kurulacak olması, efektif ilçe bağlantıları yapılarak daha fazla insanın kolay bir şekilde YHT hizmetini kullanması trafik yoğunluğu sorununa büyük etki edecektir. Bu bağlamda belediye otobüslerinin YHT istasyonu için ilçe bağlantılarının sağlanmasında Çok Kriterli Karar Verme (ÇKKV) yöntemlerinden AHP (Analytic Hierarchy Process), TOPSIS (Technique for Order Preference by Similarity to An Ideal Solution) ve PROMETHEE (The Preference Ranking Organization Method for Enrichment Evaluation) entegre şekilde kullanılmıştır. Yöntem sonuçları karşılaştırıldığında Kırıkkale Üniversitesi – Osmangazi hattı için 2. güzergâhın seçildiği görülmekte olup, diğer ilçeler için de alternatif güzergâhların sıralamaları elde edilmiştir. Çalışma, Kırıkkale’de açılacak YHT durağı ile ilçelerin ve binlerce öğrencisi bulunan üniversitenin bağlantısını sağlamakta olduğundan, il bazında yapılmış en kapsamlı çalışma özelliğini taşımasının yanı sıra YHT için güzergâh belirleme çalışması olarak da literatüre önemli bir katkı sağlamaktadır.","PeriodicalId":17899,"journal":{"name":"Konya Journal of Engineering Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83364002","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}

This technology is now an important therapeutic system for medical science. In this system, the electrical current pulse is applied over the skin through the inner layers via electrodes to activate excitable tissue layers. Activating other excitable tissue layers may cause discomfort. Thus, it is vital to design electrode configuration arrangements to activate the target anatomical layers without affecting the neighboring ones. A device for primary headaches showed mixed results. This may be related to the electrode position that requires higher stimulus current levels to activate target nerve fibers. This may stimulate neighboring nerve fibers which resulted in the discomfort of patients. A feasible solution is to identify the optimal electrode configuration based on the activation function which is the second derivative of the electric potential along an axon. This may guide to estimate of the possibility of action potential generation on the neural tissue layer using a specified electrode arrangement. In this study, the multilayered human head was developed based on MRI data set using pre and post-processing. Then multi-electrode arrangements were developed to examine the possible nerve activation location. Results showed that the nerve fibers were activated at the same location of the trajectory for the anodal and cathodal stimulation. This may be proof that the activation function can be used to define the optimal location of nerve activation. This may lead to lower thresholds for similar therapeutic benefits in transcutaneous electrical nerve stimulation with decreased power consumption.","PeriodicalId":17899,"journal":{"name":"Konya Journal of Engineering Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89602860","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}

In addition, experience in sleep staging also creates different decisions for sleep experts. The search for finding an effective automatic sleep staging system has been accelerated in the last few years. There are many studies dealing with this problem but very few of them were conducted with real sleep data. Studies have been carried out on mostly processed and cleaned-ready data sets. In addition, there are few studies in which the data distribution in sleep stages is balanced (equal numbers of epochs from each stage are used), and it is seen that the performance of these studies is quite low compared to other studies. When the literature studies are examined, there is a wide range of studies in which many features are extracted, many feature selection methods are used, many classifiers are applied and various combinations of these are available. For this reason, to determine the best-performing features and the most powerful features, 168 features were extracted from the real EEG, EOG, and EMG signals of 124 patients. These features were selected with 7 different feature selection methods, and classification was carried out with 4 classifiers. In general, the ReliefF feature selection method has performed best, and the Bagged Tree classifier has reached the highest classification accuracy of 67.92% with the use of nonlinear features.","PeriodicalId":17899,"journal":{"name":"Konya Journal of Engineering Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86902713","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}

It shows excellent osteoconductivity, osteoinductivity, and good biocompatibility properties, as its chemical composition is similar to the original chemical structure of bone. Herein, we designed β-TCP-PLA composite scaffolds containing two different concentrations of silicate additives. We aimed to investigate the effect of silicate-additive with varying concentrations (0.8% and 1%) on osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hMSCs) seeded flexible bone grafts. The morphological structure of β-TCP-PLA-based bone grafts was assessed by scanning electron microscopy (SEM) and the tensile strength of grafts was evaluated. The results showed that scaffolds had porous and flexible structures. hMSCs osteogenic differentiation was evaluated with the alkaline phosphatase (ALP) activity and DNA content measurements. Compared with β-TCP-PLA grafts, these designed synthetic flexible bone grafts with 0.8% and 1% silicate-additive significantly promoted hMSCs proliferation and osteogenic differentiation. Moreover, 0.8% silicate-additive β-TCP-PLA grafts showed increased ALP activity. The outcomes of the present study suggest that synthetic flexible bone grafts with silicate-additive might be useful for encouraging the regeneration of bone.","PeriodicalId":17899,"journal":{"name":"Konya Journal of Engineering Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81602824","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}
