A new method for automated estimation of joint roughness coefficient for 2D surface profiles using power spectral density
Unlusoy, Deniz; Süzen, Mehmet Lütfi (Elsevier BV, 2020-01-01)
In this study, a new method for the objective and accurate estimation of the joint roughness coefficient (JRC) of surface profiles, which are extracted from terrestrial laser scanner point clouds, is proposed. The requirements of objectivity, accuracy, reliability, and suitability for automatic analysis have been the basic criteria in assessing the performance of the procedure for JRC estimation. The procedure to estimate the JRC value of a sample profile is based on a similarity measure, between the third-...
Improvement of statistical landslide susceptibility mapping by using spatial and global regression methods in the case of More and Romsdal (Norway)
Erener, Arzu; Düzgün, Hafize Şebnem (Springer Science and Business Media LLC, 2010-03-01)
Statistical models are one of the most preferred methods among many landslide susceptibility assessment methods. As landslide occurrences and influencing factors have spatial variations, global models like neural network or logistic regression (LR) ignore spatial dependence or autocorrelation characteristics of data between the observations in susceptibility assessment. However, to assess the probability of landslide within a specified period of time and within a given area, it is important to understand th...

A new method for determining the depth of cut using power shovel monitoring
Karpuz, Celal; BOZDAG, T (Springer Science and Business Media LLC, 2001-01-01)
The method based on the power shovel monitoring is described for determining the depth of cut and the value of power consumption depending on the rock strength and the dipper position in digging operation. The investigations into mining shoves operating at different open-pit mines of Turkish Coal Enterprises were carried out.
Experimental evaluation of geomembrane/geotextile interface as base isolating system
Kalpakci, V.; Bonab, A. T.; Özkan, M. Yener; Gülerce, Zeynep (Thomas Telford Ltd., 2018-02-01)
The objective of this study is to evaluate the effect of the geomembrane/geotextile interface on the seismic response of small-to-moderate height structures. Three building models with first-mode natural frequencies changing between 2-4 Hz (representing two, three and four storey structures) were tested with and without the addition of geomembrane/geotextile interface using the shaking table test setup by employing harmonic and modified/ scaled ground motions. Experimental results showed that the geomembran...
