3-D Vibration analysis of the rectangular micro damaged plates
(Springer, 2008)In the present work, damaged plates are modeled by the micro-elongation theory which neglects the micropolar effects in Eringen's microstretch theory. The wave propagation problem is Studied and a new wave which does not ... -
Quality assessment of 3D building data
(Wiley-Blackwell Publishing, 2010-12)Three-dimensional building models are often now produced from lidar and photogrammetric data. The quality control of these models is a relevant issue both from the scientific and practical points of view. This work presents ... -
Determining pull - out deformations of bonded metal anchors embedded in concrete by means of photogrammetry
(International Society for Photogrammetry and Remote Sensing, 2012)Chemical anchorages are applied in many engineering implementations, particularly strengthening of reinforced concrete structures. During strengthening procedure; chemical anchorages should be tested, since they supply to ... -
Laboratory flume experiment with a coded structured light system
(International Society for Photogrammetry and Remote Sensing, 2012)The topography of inland deltas is influenced chiefly by the water-sediment balance in distributary channels and local evaporation and seepage rates. In a previous study, a reduced complexity model has been applied to ... -
Co-registration of 3d point clouds by using an errors-in-variables model
(Copernicus Gesellschaft MBH, 2012-08-25)Co-registration of point clouds of partially scanned objects is the first step of the 3D modeling workflow. The aim of co-registration is to merge the overlapping point clouds by estimating the spatial transformation ... -
Photogrammetric monitoring of an artificially generated shallow landslide
(Wiley-Blackwell, 2013-06)An artificial rainfall event was applied to a forested slope in Ruedlingen, northern Switzerland. The experiment triggered a landslide which resulted in mobilising about 130m3 of debris. The event was monitored by a ... -
Total least squares registration of 3D surfaces
(Copernicus GmbH, 2013-10-16)Co-registration of point clouds of partially scanned objects is the first step of the 3D modeling workflow. The aim of coregistration is to merge the overlapping point clouds by estimating the spatial transformation ... -
Photogrammetric deformation monitoring of the second Bosphorus Bridge in Istanbul
(International Society for Photogrammetry and Remote Sensing, 2014)Improving the efficiency of bridge inspection and minimizing the impact of dynamic load on the long term deterioration of the bridge structure reduces maintenance and upkeep costs whilst also improving bridge longevity and ... -
A novel nonreflecting boundary condition for unsteady flow
(Wiley-Blackwell, 2014-01-10)A novel nonreflecting boundary condition, which converges to the specified time-dependent boundary condition within any degree of accuracy, is introduced for the numerical simulation of hyperbolic systems and validated ... -
Compressive split-step Fourier method
(Işık University Press, 2015-02-09)In this paper an approach for decreasing the computational effort required for the split-step Fourier method (SSFM) is introduced. It is shown that using the sparsity property of the simulated signals, the compressive ... -
Determining pull-out deformations by means of an online photogrammetry monitoring system
(Cem Gazioğlu, 2015-03-02)Chemical anchorages are applied in many engineering implementations, particularly strengthening of reinforced concrete structures. During strengthening procedure; chemical anchorages should be tested, since they supply to ... -
RETRACTED: Efficiency analysis of the dynamic traffic control for an urban highway (Retracted article. See 185, 2016)
(Springer International Publishing AG, 2015-03-07)In this study, dynamic traffic control strategies, namely dynamic ramp metering and dynamic speed limit control, have been examined through microscopic traffic simulation based on site measurements. In this context, the ... -
Energy dissipation characteristics of slab type buildings with special connectors
(National Technical University of Athen, 2015-05-25)The latest developments in the construction technologies and the materials facilitated the practicing engineers to go higher and energy-efficient buildings. However, the safety of the buildings and the residents has been ... -
