We evaluated the performance of a parallel 3D FDM simulation of seismic wave propagation using the Intel Xeon Phi coprocessor. We confirmed that MPI/OpenMP hybrid parallel computing with hyper-threading is more efficient than pure MPI parallelism. The performance of the thread parallel computing was further improved by fusing the original three DO loops of major kernel routines into two DO loop...

Recently, a marching-on in degree finite difference method (MOD-FDM) was employed in the finite-difference time-domain (FDTD) formulation to obtain unconditionally stable transient responses. The objective of this work is to implement a plane wave excitation in the MOD-FDM formulation for scattering problems for an open region. This formulation has volume electric and magnetic current densities...

fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

In this paper we discuss mismatches between two database schemes (here referred to as ontologies), produced for the UNIKb prototype. We present a (new) classification of system-communication mismatches after we discuss the occurrence of these mismatches between the Cardiff University and Liverpool University ontologies. Thereafter, we investigate to what extent the mismatches can be resolved. W...

3D printing on textile fabrics has been investigated intensively during the last years. A critical factor is adhesion between printed polymer and fabric, limiting potential areas of application. Especially safety-related applications, e.g. stab-resistant textile/polymer composites, need to show reliable both components serve their purpose. Here we investigate possibility sandwiching textiles 3D...

in this paper an application of gustafson-kessel clustering algorithm is presented to create a fault detection map (fdm). five post-stack seismic attributes are extracted from a desired seismic time slice related to 3d seismic data of a gas field located in southwest of iran. to find the optimal cluster numbers, two frequently used clustering validity measures, i.e. sc and xb, are used and then...

BACKGROUND The canonical Wnt signaling pathway plays important roles in cellular proliferation and differentiation, axonal outgrowth, cellular maintenance in retinas. Here we test the hypothesis that elements of the Wnt signaling pathway are involved in the regulation of eye growth and prevention of myopia, in the mouse form-deprivation myopia model. METHODOLOGY/PRINCIPAL FINDINGS (1) One hun...

BACKGROUND With additive manufacturing (AM) individual and biocompatible implants can be generated by using suitable materials. The aim of this study was to investigate the biological effects of polylactic acid (PLA) manufactured by Fused Deposition Modeling (FDM) on osteoblasts in vitro according to European Norm / International Organization for Standardization 10,993-5. METHOD Human osteobl...
