Robust confidence intervals for the difference of two independent population variances
(Hacettepe Unıv, Fac Scı, 2020)In this study, we propose confidence intervals and their bootstrap versions for the difference of variances of two independent population using some robust variance estimators. The proposed confidence intervals are compared ... -
Effect of tantalum contents on transformation temperatures, thermal behaviors and microstructure of CuAlTa HTSMAs
(Sprınger, 2020)In this study, CuAl13-xTax (% mass x = 1; 1.5; 2; 2.5) shape-memory alloys were produced through arc-melting method. Phase transformation temperatures were investigated by using differential scanning calorimetry (DSC) and ... -
DCCMED-Net: Densely connected and concatenated multi Encoder-Decoder CNNs for retinal vessel extraction from fundus images
(Churchıll Lıvıngstone, 2020)Recent studies have shown that convolutional neural networks (CNNs) can be more accurate, efficient and even deeper on their training if they include direct connections from the layers close to the input to those close to ... -
Cascaded deep convolutional encoder-decoder neural networks for efficient liver tumor segmentation
(Churchıll Lıvıngstone, 2020)Liver and hepatic tumor segmentation remains a challenging problem in Computer Tomography (CT) images analysis due to its shape variation and vague boundary. The general hypothesis says that deep learning methods produce ... -
The effects of pretreatment with lithium metaborate dihydrate on lipid peroxidation and Ca, Fe, Mg, and K levels in serum of Wistar albino male rats exposed to Cd
