Three full scale field experiments reported by De Beer&Wallays (1972) and Esu&D'Elia (1974) have been modeled using 3D finite element method with PLAXIS 3D. Shear box models were established to eliminate the effect of site geometries and slope angles which were not reported in these cases. Lateral movement of an unstable soil and loading of passive piles were generated by prescribed horizontal surface displacements in the upper half of the shear box model. Measured field values of pile deflection, bending moment and shear force distributions through the pile shafts were obtained with these models. In addition, the accuracy of the 3D finite element method was compared with the accuracy of the other researchers' predictions for these field experiments. According to the analyses results in this study, it can be stated that the proposed 3D models can realistically predict the measured field values. Calculation accuracy of the methodology is verified for uniformand non-uniformhorizontal soil movement profiles, different pile rigidity and pile materials, granular and cohesive soil material alternatives and different drainage conditions.

Modeling of dispersion in a polymeric chromatographic monolith
Koku, Harun; Schure, Mark R.; Lenhoff, Abraham M. (Elsevier BV, 2012-05-11)
Dispersion in a commercial polymeric monolith was simulated on a sample geometry obtained by direct imaging using high-resolution electron microscopy. A parallelized random walk algorithm, implemented using a velocity field obtained previously by the lattice-Boltzmann method, was used to model mass transfer. Both point particles and probes of finite size were studied. Dispersion simulations with point particles using periodic boundaries resulted in plate heights that varied almost linearly with flow rate, a...
Analysis of Alternative Performance Metrics for Compressive Spectral Imaging
Gundogan, Utku; Öktem, Sevinç Figen (null; 2020-10-07)
Compressive spectral imaging is a technique that reconstructs the three-dimensional (3D) spectral data cube from limited number of two-dimensional (2D) measurements. In order to obtain this data cube, the technique makes use of the theory of compressed sensing, and employs both an optical and a computational system. However, this optical system can be designed with multiple variations. To evaluate the performance of different designs, there is a need for metrics that are reliable and fast to compute. Curren...
Image-based extraction of material reflectance properties of a 3D rigid object
Erdem, ME; Erdem, IA; Yilmaz, UG; Atalay, Mehmet Volkan (2004-01-01)
In this study, an appearance reconstruction method based on extraction of material reflectance properties of a three-dimensional (3D) object from its two-dimensional (2D) images is explained. One of the main advantages of this system is that the reconstructed object can be rendered in real-time with photorealistic quality in varying illumination conditions. The reflectance of the object is decomposed into diffuse and specular components. While the diffuse component is stored in a global texture, the specula...
Image-based extraction of material reflectance properties of a 3D object
Erdem, Mehmet Erkut; Atalay, Mehmet Volkan; Department of Computer Engineering (2003)
In this study, an appearance reconstruction method based on extraction of material re?ectance properties of a three-dimensional (3D) object from its twodimensional (2D) images is explained. One of the main advantages of this system is that the reconstructed object can be rendered in real-time with photorealistic quality in varying illumination conditions. Bidirectional Reflectance Distribution Functions (BRDFs) are used in representing the reflectance of the object. The reflectance of the object is decompos...
Investigation of effect of design and operating parameters on acoustophoretic particle separation via 3D device-level simulations
Sahin, Mehmet Akif; ÇETİN, BARBAROS; Özer, Mehmet Bülent (Springer Science and Business Media LLC, 2019-12-16)
In the present study, a 3D device-level numerical model is implemented via finite element method to assess the effects of design and operating parameters on the separation performance of a microscale acoustofluidic device. Elastodynamic equations together with electromechanical coupling at the piezoelectric actuators for the stress field within the solid parts, Helmholtz equation for the acoustic field within fluid, and Navier-Stokes equations for the fluid flow are coupled for the simulations. Once the zer...
