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 ... -
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 ... -
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. -
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 ... -
A generic point error model for TLS derived point clouds
(SPIE-Int Soc Optical Engineering, 2017-06-26)This work aims at developing a generic and anisotropic point error model, which is capable of computing magnitude and direction of a priori random errors, described in the form of error ellipsoids for each individual point ... -
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. ... -
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 ... -
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 ... -
3-Dimensional pre- and post-fire comparison of forest areas
(International Society for Photogrammetry and Remote Sensing, 2018-03-06)Forest agencies give special attention to forest fires where post-disaster loss can rarely be gauged in a quick and economic way unless an appropriate technology is adopted. Determination of the planimetric and volumetric ... -
