Improvement of engineering properties and liquefaction reduction of sandy soils using electric arc furnace slag and roof tile powder

Agolli, Drinela

The scarcity of suitable land for construction of engineering facilities and shortage of natural earth aggregates has highlighted the need for finding innovative way of construction. Nowadays problematic soils such as: soft clay, organic soils and liquefiable soils can be improved to the required civil engineering requirements by application of soil stabilization. Soil stabilization is a method intended to increase or preserve the stability of soil mass and chemical alteration of soil to improve engineering properties. Generally, ground treatment techniques used are: densification, reinforcem ...Daha fazlası

Preparation and characterization of carbon-based nanofluids Karbon bazlı nanoakışkanların hazırlanması ve karakterizasyonu

Fidan-Aslan, Tuğçe

ABSTRACTNanofluids are produced by the addition of nano-sized particles to the base fluid in order to increase the thermal conductivity of heat transfer fluids. Preparation of stable nanofluids with high thermal conductivity is a very complex process and their usage in heat transfer applications are related to many important parameters from the stability of nanofluids to their viscosity. Optimization of these parameters is essential for the practical use of nanofluids. The objectives of this study are to successfully preparecarbon-based nanofluids while investigating the stability mechanisms a ...Daha fazlası

Heart Attack Analysis Detection System Using Machine Learning Methods

SERDAR YANIK

In order to investigate Heart Attack Analysis and Detection Using Machine Learning Methods, models that predict the type of news in a new condition determined by using Machine Learning Models have been studied. In particular, the performance of various classifiers, including logistic regression, Knearest neighbour (KNN), support vector machine (SVM), Naive Bayes and decision tree, is compared. In the experiments using a real-life dataset, logistic regression and SVM gave the best results with a test accuracy of 90%. Naive Bayes achieved an accuracy of 86.67%, KNN 83.33% and decision tree 63.33 ...Daha fazlası
