This study investigates the optimum weld area on a popular aerospace alloy (i.e., Inconel 825) made by the electron beam welding technique. Welding speed (S), beam current (I), accelerating voltage (V), and beam oscillation (O) are considered as process parameters to study the weld bead area (WA) of the weldments. An instructive study on multiple non-linear neural regression analyses has been done as a basic introduction to neuro regression modeling with artificial neural network (ANN) philosophy. To do this, the experimental prediction has been modeled with 14 predictive functional structures ...Daha fazlası
The Internet of Things (IoT) provides solutions to many daily life problems. Smartphones with user-friendly applications make use of artificial intelligence solutions offered by deep learning techniques. In this work, we provide a sustainable solution to automatically monitor and control the irrigation process for detected flowers by combining deep learning and IoT techniques. The proposed flower status tracker and self-irrigation system (FloTIS) is implemented using a cloud-based server and an Android-based application to control the status of the flower which is being monitored by the local ...Daha fazlası
Abstract This study is prepared to examine the effects of Turkish character usage on text data by using multiple classifiers. Regression Classifiers, SVM, NB-Classifiers, and ANN are frequently used in supervised learning methods, especially in classification problems. Regression classifiers generally come in two types: as Linear and Logistic. There are also more than one type of Naive Bayes classifier. In our study, after mentioning the properties of Linear Regression and Logistic Regression classifiers in general terms, why Logistic Regression is much more suitable for this study is explaine ...Daha fazlası
Abstract In this study, machine learning-based models have been used to estimate the return loss parameters of the operational resonant frequency of the U-slotted UHF RFID antenna. The data set utilized, consisting of 544 instances, has been collected from the simulation software as a consequence of the parametric evaluation of the antenna design parameters. Distinct machine learning methods have been used on two different types of output data, complex and linear scattering parameters, and the models' prediction performance has been evaluated. In the single-output regression models, a mean-squ ...Daha fazlası
ABSTRACTThis thesis presents an online learning stable robust adaptive controller design for the chaos control of the brushless direct current (BLDC) motor. The proposed adaptive controller algorithm consists of a Wiener model-based controller with a nonlinear auto-regressive moving-average (NARMA) based artificial neural network (ANN), and a Hammerstein based plant model. The developed online learning closed-loop control system providing stability and robustness might be defined as an auto-regressive moving average (ARMA) based system identification problem with partially known parameters.

ÖZETPratik kullanım amaçlı üretim sırasında kusur oluşturmadan ince bir grafen/altıgen bor nitrür (GBN) hibrit yaprağı üretmek neredeyse imkansızdır. Bu araştırmada, iki farklı yapı türü hakkında ayrıntılı bir tartışma yapılmıştır. İlk olarak, elmas şeklinde bir grafen (G) adası barındıran altıgen bor nitrür (h-BN) nano yaprak (XG @ h-BN) analiz edildi. İkinci olarak, elmas şekilli bir h-BN adası barındıran grafen nano yaprak (Xh-BN @ G) incelenmiştir. X, elmas şekilli adacığın boyutunu göstermekte olup 4, 9 ve 16 değerlerini almaktadır. Elmas şekle sahip olan bir adacıkta en küçük hücre altıg ...Daha fazlası

The purpose of this study is to investigate the topic of mathematical and spatial relationships, to clarify what linguistics has provided in this field, and to identify these relationships in the process of linguistic creation, and to determine the function of language, following this descriptive and analytical approach. It is noteworthy that these two terms are modern, but we do not mention the concept in the books of our ancient scholars; They talked about various techniques that may affect the formal and semantic enrichment of the patterns of linguistic formation, including: Deletion, Metap ...Daha fazlası
2020 is the International Year of the Nurse and Midwife and the 200th anniversary of Florence Nightingale’s birth; a year meant for celebration, and a deeper look at the importance of the nursing role in the future of healthcare. Today, due to the COVID-19 pandemic, the role of the nurse and the urgent need for investment of this precious resource is at the forefront of many health policy makers’ agendas. As we entered 2020, many countries were already facing a nursing shortage. The World Health Organization’s first State of the World’s Nursing report, launched in April this year, reported a g ...Daha fazlası

ABSTRACTIn this thesis, the economic analysis of water storage by rainwater harvesting technique at Izmir Katip Celebi university (IKCU) was studied. The data from the flowmeters, which were installed in the men-women toilets in the central classrooms, were recorded, and the catchment area was calculated. According to the data, the amount of rainwater to be collected can meet the water demand in the toilets flushing. Theeconomic analysis of the rainwater harvesting (RWH) was made for three scenarios their difference in initial cost by the calculations of the payback period (PBP), the net prese ...Daha fazlası
