Precursors of instability in a natural slope due to rainfall: a full-scale experiment
(Springer Heidelberg, 2018-09)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) ... -
Rogue wavefunctions due to noisy quantum tunneling potentials
(Işık University Press, 2017-02-02)In this paper, we study the effects of white-noised potentials on nonlinear quantum tunneling. We use a split-step scheme to numerically solve the nonlinear Schrodinger equation (NLSE) with a tunneling potential. We consider ... -
Coupled influence of content, gradation and shape characteristics of silts on static liquefaction of loose silty sands
(Elsevier Sci Ltd, 2017-10)Static liquefaction is a challenging problem of geotechnical engineering as its consequences are generally catastrophic when they occur on site. Previous laboratory studies focused on various factors that could influence ... -
A decision making support tool for selecting green building certification credits based on project delivery attributes
(Pergamon-Elsevier Science Ltd, 2017-12)The Green Building (GB) certification process embodies detailed requirements and specifications that lead to additional tasks for project teams, which increases complexity levels of the entire project delivery process. ... -
Behaviour of steel cushions subjected to combined actions
(Springer, 2018-02)Mild steel is relatively low-cost and easily accessible material to fabricate some structural members. It would be a significant advantage if seismic energy dissipaters that are used in structures constructed in the ... -
Assessment and enhancement of SAR noncoherent change detection of sea-surface oil spills
(IEEE, 2018-01)Oil spills are one of the most dangerous catastrophes that threaten the oceans. Therefore, detecting and monitoring oil spills by means of remote sensing techniques that provide large-scale assessments is of critical ... -
Shapes and statistics of the rogue waves generated by chaotic ocean current
(International Society of Offshore and Polar Engineers, 2016)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
(International Society for Photogrammetry and Remote Sensing, 2016)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 ... -
Retraction Note: Efficiency analysis of the dynamic traffic control for an urban highway
(Springer International Publishing AG, 2016-08-16)The authors and the Editor-in-Chief have agreed to retract this article [1] due to excessive overlap with previously published content. Moreover, no proper reference was given to the respective sources. -
Monitoring of a laboratory-scale inland-delta formation using a structured-light system
(Blackwell Publishing Ltd, 2016-06)A reduced complexity model, which simulates the process of fluvial inland-delta formation, has been developed in a previous study. The results have been compared and validated with a laboratory experiment. This work ... -
Rogue wave spectra of the Kundu-Eckhaus equation
(American Physical Society, 2016-06-15)In this paper we analyze the rogue wave spectra of the Kundu-Eckhaus equation (KEE). We compare our findings with their nonlinear Schrodinger equation (NLSE) analogs and show that the spectra of the individual rogue waves ... -
Rogue waves of the Kundu-Eckhaus equation in a chaotic wave field
(American Physical Society, 2016-03-01)In this paper we study the properties of the chaotic wave fields generated in the frame of the Kundu-Eckhaus equation (KEE). Modulation instability results in a chaotic wave field which exhibits small-scale filaments with ... -
Compressive spectral method for the simulation of the nonlinear gravity waves
(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 ... -
Historical analysis of economic, social and environmental impacts of the Europe-Asia crossings in Istanbul
(Taylor & Francis Inc, 2016)Achieving economic, social, and environmental sustainability of urban transport is one of the great contemporary societal challenges. By tracing urban land-use and transport policies and technological change in transport ... -
Energy dissipation characteristics of slab type buildings with special connectors
