  • Compressive spectral method for the simulation of the nonlinear gravity waves 

    Bayındır, Cihan (Nature Publishing Group, 2016-02-25)
    In this paper an approach for decreasing the computational effort required for the spectral simulations of the fully nonlinear ocean waves is introduced. The proposed approach utilizes the compressive sampling algorithm ...
  • Early detection of rogue waves by the wavelet transforms 

    Bayındır, Cihan (Elsevier, 2016-01-08)
    We discuss the possible advantages of using the wavelet transform over the Fourier transform for the early detection of rogue waves. We show that the triangular wavelet spectra of the rogue waves can be detected at early ...
  • A novel nonreflecting boundary condition for unsteady flow 

    Zafer, Baha; Delale, Can Fuat (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 ...
  • Photogrammetric Monitoring of an Artificially Generated Shallow Landslide 

    Akça, Mehmet Devrim (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 ...
  • Precursors of instability in a natural slope due to rainfall: a full-scale experiment 

    Askarinejad, Amin; Akça, Mehmet Devrim; Springman, Sarah Marcella (Springer Heidelberg, 2018-09-01)
    A full-scale landslide-triggering experiment was conducted on a natural sandy slope subjected to an artificial rainfall event, which resulted in mobilisation of 130m(3) of soil mass. Novel slope deformation sensors (SDSs) ...
  • Quality assessment of 3D building data 

    Akça, Mehmet Devrim; Freeman, Mark; Sargent, Isabel; Gruen, Armin (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 ...
  • Uni-axial behavior of energy dissipative steel cushions 

    Özkaynak, Hasan; Khajehdehi, Arastoo; Güllü, Ahmet; Azizisales, Faraz; Yüksel, Ercan; Karadoǧan, Hüseyin Faruk (Techno Press, 2018-06-25)
    Seismic excitations may impart a significant amount of energy into structures. Modern structural design attitudes tend to absorb some part of this energy through special dissipaters instead of heavy plastic deformations ...
