Öğe Predicting VO2max from submaximal exercise and non-exercise data using artificial neural networks [Yapay Sinir aglari kullanilarak submaksimal egzersiz ve egzersize dayali olmayan verilerden VO2max tahmini](2013) Akay, Mehmet Fatih; Aktürk, E.; Tunçdemir, Ali Erçe; Şen, Nezih NusretThe purpose of this study is to develop new multilayer feed-forward artificial neural network (ANN)-based maximal oxygen uptake (VO2max) prediction models by using submaximal treadmill exercise and nonexercise data. Using 10- fold cross validation on the dataset, standard error of estimate (SEE) and multiple correlation coefficient (R) of the models are calculated. It is shown that the models including submaximal, standard nonexercise and questionnaire variables yield higher R and lower SEE than the ones including submaximal and standard nonexercise variables only. The results of ANN-based models are also compared with the ones obtained by Multiple Linear Regression (MLR) and Support Vector Machines (SVM). It is shown that ANN-based models perform better than MLR and SVM-based models for predicting VO2max.Öğe Data fusion in satellite images and their quantitative analysis [Uydu görüntülerinde veri karilmasi ve nicel analizi](2009) Ugurlu, Bora; Yildirim, Hülya; Özel, Mehmet EminData fusion may be considered a kind of complex image processing method which combines the different satellite images to bring complementary and useful information into one single composite image. The fused image will usually have better spectral and spatial resolutions to see more detailed and sometimes new features not seen in the original images. In the present work, Landsat 7 ETM, 1999 dated satellite data which is belong to Canakkale Province is used. The multispectral satellite image that is rich spectrally and panchromatic(PAN) image that is rich spatially but poor spectrally are fused by using two different methods based on Intensity,Hue,Saturation (IHS) Transformation and Principal Component Analysis. Both of the methods are assessed by looking through the relationship between the vegetation indexes of final images and multispectral satellite image.Öğe Sub-mıcrometrıc study of cu- and hg-bearıng opaque assemblages ın unshocked prımıtıve h chondrıtes: orıgın and fırst occurrence of natıve hg ın a meteorıte(WILEY, 2009) Caillet-Komorowski, C.; Boudouma, O.; El Goresy, A.; Miyahara, M.; Özel, Mehmet Emin
