An unsupervised learning algorithm: application to the discrimination of seismic events and quarry blasts in the vicinity of Istanbul

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz; Yıldırım, Engin (COPERNICUS GESELLSCHAFT MBH, 2011)

The results of the application of an unsupervised learning (neural network) approach comprising a Self Organizing Map (SOM), to distinguish micro-earthquakes from quarry blasts in the vicinity of Istanbul, Turkey, are ...
Application of Artificial Neural Networks to Estimate Wastewater Treatment Plant Inlet Biochemical Oxygen Demand

Doğan, Emrah; Ateş, Asude; Eren, Beytullah (WILEY, 2008)

Biochemical oxygen demand (BOD) has been shown to be an important variable in water quality management and planning. However, BOD is difficult to measure and needs longer time periods (5 days) to get results. Artificial ...
Application of k-means and Gaussian mixture model for classification of seismic activities in Istanbul

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz (COPERNICUS GESELLSCHAFT MBH, 2012)

Two unsupervised pattern recognition algorithms, k-means, and Gaussian mixture model (GMM) analyses have been applied to classify seismic events in the vicinity of Istanbul. Earthquakes, which are occurring at different ...
Application of trend analysis and artificial neural networks methods: The case of Sakarya River

Çeribaşı, Gökmen; Doğan, Emrah; U. Akkaya; U. E. Kocamaz (SHARIF UNIV TECHNOLOGY, 2017)

Various artificial intelligence techniques are used in order to make prospective estimations with available data. The most common and applied method among these artificial intelligence techniques is Artificial Neural ...
APPLICATION OF TREND ANALYSIS METHOD ON RAINFALL STREAM FLOW-SUSPENDED LOAD DATAS OF WEST AND EAST BLACK SEA BASINS AND SAKARYA BASIN

Çeribaşı, Gökmen; Doğan, Emrah (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2016)

In hydraulic engineering, it is of vital importance to estimate suspended load correctly in planning and projecting stream structures. On the other hand, problems increase with the effect of heating and climate changes in ...
Clustering Seismic Activities Using Linear and Nonlinear Discriminant Analysis

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz (388 LIMO RD, WUHAN, CHINA MAINLAND 430074, PEOPLES R CHINA, 2014)

Identification and classification of different seismo-tectonic events with similar characteristics in a region of interest is one of the most important subjects in seismic hazard studies. In this study, linear and nonlinear ...
COMPARISON OF MODIFIED GRID LASER PHOTOCOAGULATION AND INTRAVITREAL RANIBIZUMAB INJECTION FOR DIFFUSE DIABETIC MACULAR EDEMA

Çelik, Eyüp; Çakır, Burçin; E. B. Turkoglu; Doğan, Emrah; Erdoğan, Garip; Alagöz, Gürsoy (WICHTIG PUBL, 2015)
Development of artificial neural network for prediction of salt recovery by nanofiltration from textile industry wastewaters

Eren, Beytullah; İleri, Recep; Doğan, Emrah; Çağlar, Naci (TAYLOR & FRANCIS INC, 2012)

This paper presents the use of artificial neural network (ANN) to develop a model for predicting rejection rate (R-o) of single salt (NaCl) by nanofiltration based on experimental datasets. The rejection rates of NaCl were ...
Discrimination of quarry blasts and earthquakes in the vicinity of Istanbul using soft computing techniques

Yıldırım, Eray; Gülbağ, Ali; Horasan, Gündüz; Doğan, Emrah; Yıldırım, Engin (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

The purpose of this article is to demonstrate the use of feedforward neural networks (FFNNs), adaptive neural fuzzy inference systems (ANFIS), and probabilistic neural networks (PNNs) to discriminate between earthquakes ...
Dissolved oxygen estimation using artificial neural network for water quality control

Şengörür, Bülent; Doğan, Emrah; Köklü, Rabia (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2006)

Dissolved oxygen (DO) is one of the key parameters when analyzing river water quality. Correct estimation of DO being carried by a river is very important for water quality control. DO is affected by lots of variables such ...
Effects of anthropogenic activities on the Lower Sakarya River

Işık, Sabahattin; Doğan, Emrah; Şaşal, Mustafa (ELSEVIER SCIENCE BV, 2008)

We investigate the effects of anthropogenic activities on the Lower Sakarya River. The impacts of dam, levee, and bridge constructions, sand-gravel mining activities and water withdrawals during the industrialization period ...
Effects of artificial tear treatment on corneal epithelial thickness and cornea topography findings in dry eye patients

Çakır, Burçin; Doğan, Emrah; Çelik, Eyüp; T. Babashli; T. Ucak; Alagöz, Gürsoy (MASSON EDITEUR, 2018)

Conclusion.- Artificial tear treatment in dry eye patients seems to increase central corneal epithelial and mid-peripheral corneal thicknesses. Measurement of corneal epithelial thickness can be a useful tool for evaluation ...
