A Multi-scale approach to characterization of volcanic natural pozzolans/
Sassani, Alireza; Turanlı, Lütfullah; Meral, Çağla; Department of Civil Engineering (2014)
Three types of volcanic rocks, namely perlite, a zeolite-rich volcanic tuff and a feldspar-rich volcanic tuff were selected to represent the general group of Volcanic Natural Pozzolans (VNPs). The target group was those volcanic natural pozzolans which intrinsically possess pozzolanic properties, i.e. do not require heat-treatment to obtain pozzolanic reactivity. X-ray Fluorescence (XRF), Powder X-Ray Diffraction (XRD), Blaine air permeability test, Laser diffraction, thermogravimetry (TGA), solid-state 29S...

The point spread function (PSF) is the most widely used tool for quantifying the spatial resolution of imaging systems. However, prerequisites for the proper use of this tool are linearity and space invariance. Because EIT is non-linear it is only possible to compare different reconstruction algorithms using a standard data set. In this study, the FEM is used to generate simulation data, which are used to investigate the non-linear behaviour of EIT, the space dependence of its PSF and its capability of reso...
A Study on optimum layout of drainage gallery for concrete dams
Daghestani, Tameem; Yanmaz, Ali Melih; Çalamak, Melih; Department of Civil Engineering (2018)
Dams are generally massive structures retaining a large amount of water. Any failure could lead to a disaster. Therefore, keeping the dam within the required safety margins and maintaining those conditions is of the utmost importance. A gravity dam is held in place by its own weight. Uplift pressure reduces the effective weight of the dam, thus reducing its safety. Hence reducing the effect of uplift could have significant results in increasing the safety of the dam. In this study, the optimum location of t...
An efficient method for snore/nonsnore classification of sleep sounds
Cavusoglu, M.; Kamasak, M.; Erogul, O.; Çiloğlu, Tolga; Serinağaoğlu Doğrusöz, Yeşim; Akcam, T. (IOP Publishing, 2007-08-01)
A new method to detect snoring episodes in sleep sound recordings is proposed. Sleep sound segments ( i.e., 'sound episodes' or simply 'episodes') are classified as snores and nonsnores according to their subband energy distributions. The similarity of inter- and intra-individual spectral energy distributions motivated the representation of the feature vectors in a lower dimensional space. Episodes have been efficiently represented in two dimensions using principal component analysis, and classified as snor...
