• Shapes and statistics of the rogue waves generated by chaotic ocean current 

  Bayındır, Cihan (International Society of Offshore and Polar Engineers, 2016-06-26)

  In this study we discuss the shapes and statistics of the rogue (freak) waves emerging due to wave-current interactions. With this purpose, we use a simple governing equation which is a nonlinear Schrödinger equation (NLSE) ...

• An emprical point error model for TLS derived point clouds 

  Akça, Mehmet Devrim (International Society for Photogrammetry and Remote Sensing, 2016-07-12)

  The random error pattern of point clouds has significant effect on the quality of final 3D model. The magnitude and distribution of random errors should be modelled numerically. This work aims at developing such an anisotropic ...

• Energy dissipation characteristics of slab type buildings with special connectors 

  Şenol, Erkan; Dindar, Ahmet Anıl; Yüksel, E.; Karadoğan, Hüseyin Faruk (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 ...

• Laboratory flume experiment with a coded structured light system 

  Akça, Mehmet Devrim; Seybold, Hansjorg; Shortis, M; Mills, J (Copernicus Gesellschaft Mbh, 2012-08-25)

  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 

  Akça, Mehmet Devrim; Aydar, Umut; Altan, Mehmet Orhan; Akyılmaz, Orhan; Shortis, M; Mills, J (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 ...

• Determining pull - out deformations of bonded metal anchors embedded in concrete by means of photogrammetry 

  Akça, Mehmet Devrim; Avşar, Edip O.; Altan, Mehmet Orhan; Doğan, Umut Anıl; Shortis, M; Mills, J (Copernicus Gesellschaft Mbh, 2012-08-25)

  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 ...

• 3-d vibration analysis of microstretch plates 

  İnan, Esin; Kırış, Ahmet (Springer, 2007)

  In the present work, rectangular plates with various boundary conditions are Studied, which are modeled by the rnicrostretch theory. Wave propagation problem is investigated and new waves are observed which do not appear ...

• 3-d vibration analysis of the rectangular micro damaged plates 

  Kırış, Ahmet; İnan, Esin (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 ...
