Sosyal bilimlerdeki birçok çalışmanın konusunu, algı, tutum veya inanç gibi doğrudan gözlemlenemeyen değişkenler oluşturmaktadır. Araştırma yöntemlerinde, böyle değişkenleri ifade edebilmek için gizli değişken veya faktör gibi terimleri kullanılmaktadırlar. Araştırmacılar, gözlenen değişkenler vasıtasıyla gözlemlenemeyen veya doğrudan ölçülemeyen gizli değişkenler veya faktörler hakkında bilgi sahibi olabilmektedirler. Gözlenen değişkenleri kullanarak gizli değişkenleri ortaya çıkarmak için, bir takım analiz yöntemleri kullanılmaktadır. Bu bağlamda sıklıkla kullanılan yöntemler, faktör analizi ...Daha fazlası

Assessment of stakeholder satisfaction as additive to improve building design quality: AHP-based approach

ERYÜRÜK, Şule | KÜRÜM VAROLGÜNEŞ, Fatma | VAROLGÜNEŞ, Sadık

It is possible to obtain better, qualified and error-free structures by evaluating the multidimensional criteria reflects all manner of opinions in the building production process. Stakeholders’ integration plays a major role in achieving this evaluation expecting the targeted quality in building production, and different priorities could be defined by various type of stakeholders. Therefore, applicable approaches should be used where the stakeholders of the building production process will be included to determine priority levels of criteria. All the criteria considered should provide that al ...Daha fazlası

Forecasting of streamflow and comparison of artificial intelligence methods: A case study for Meram Stream in Konya, Turkey

ASAAD, Mustafa Najat | ERYÜRÜK, Şule | ERYÜRÜK, Kağan

The planning and management of water resources are affected by streamflow. The analysis of the sustainability of water resources has used well-grounded methods such as artificial neural networks, used for streamflow forecasting by researchers in recent years. The main aim of this study is to evaluate the performance of various methods for long-term forecasting from the data of the mean monthly streamflows between 1981 and 2017 from the Kucukmuhsine station on the Meram Stream in the Turkish province of Konya. For that reason, the multilayer perceptron (MLP), long short-term memory (LSTM), and ...Daha fazlası

A design of experiment approach of cattle slaughterhouse wastewater treatment by electrocoagulation method

ERYÜRÜK, Kağan | ERYÜRÜK, Şule | TEZCAN ÜN, Ümran | BAKIR ÖĞÜTVEREN, Ülker

The aim of this work was to formulate an empirical model using the data of the electrochemical treatment of cattle slaughterhouse wastewater. The empirical model was developed using response surface methodology with optimal design considering an irregular process space. As operational factors, current density, influent pH, flow rate, supporting electrolyte (NaCl or Na2SO4) concentrations, and H2O2 concentrations were examined. Under these circumstances, the aim was to represent the optimal region shown generally as a surface by obtaining the lowest possible value of chemical oxygen demand (COD ...Daha fazlası

Time series modelling for goat and cow milk price index forecasting by trend analysis and Holt’s method

ERYÜRÜK, Şule | ÇİĞDEM, Hanne

Goat and cow milk is a fundamental agricultural product. Multiple factors can affect the price of milk over time such as production conditions, consumption demand, financial crisis and inflation. Dynamics of the milk price data should be considered to determine trend, cycle, or seasonality in the milk market so each pattern may affect the forecasting method should be used and the estimation results. Hence, the aim of this study is finding the pattern of the milk price time series data and estimation for the next 3 monthly periods. Historical data of Goat Milk and Cow Milk was used from the Agr ...Daha fazlası

Response surface methodology optimization of hydraulic conductivity change by microbially induced CaCO3 precipitation

ERYÜRÜK, Şule | ERYÜRÜK, Kağan

In columns packed with glass beads in the range of 0.25 mm to 3 mm in diameter, the effect of the number of cells deposited in hydraulic conductivity of porous media using CaCO3 precipitation produced by Sporosarcina pasteurii (ATCC 11859) was investigated in the present study. Following the introduction of resting Sporosarcina pasteurii cells into the columns, a precipitation solution containing 500 mM CaCl2 and 500 mM urea was injected into the columns under continuous flow conditions. To investigate the relation between deposited cell number and hydraulic conductivity, Response surface meth ...Daha fazlası

Determining Optimal Routing Solution Of A Patrol Car

AKARÇAY, Özlem | YAŞAR, Esra

Chinese Postman Problem which is dealt with in the context of the arc routing problem is one of the routing problem in 1962 in order to get the shortest turn by passing at least once on every arc on the chart. It can be used in many stations such as determining vehicle routing, tours of police patrols and determining the routes of snow removal vehicles. In this study, after explaining the basic concepts related to Chinese Postman Problem, the analysis is done through the model to find the best route over the routes that police patrol cars in a certain area have to travel.
