...., and also used to determine the locations of cracks or macro-failures. In order to analyze the source location of cracks, it is important to consider the elastic wave propagation velocity, arrival picking, source location analysis algorithm, and sensor array. However, the location of the sensor may...

The trace's corresponding coordinates are acquired by linking the pixel locations corresponding to the identified traces in an image to the 3D coordinates in the point cloud based on fusing the point cloud data...

... interactions. To overcome this limitation, this paper demonstrates the application of GPGPU (General Purpose Graphic Processing Unit) and CUDA (Compute Unified Device Architecture) C/C++ to parallelize the original sequential 2-D Y-HFDEM code along with related numerical algorithms using the GPGPU. Obtained...

The implicit updating scheme of friction force (return mapping algorithm) and Newton-Raphson iteration is newly introduced to NMM...

... are seldom undertaken. An alternative method of data collection in GPS-deprived environments became commercially available in 2012 with the introduction of the GeoSLAM Zeb-1. Localisation uses a combination of a Simultaneous Location and Mapping (SLAM) algorithm and an Inertial Measurement Unit (IMU...

..., a straightforward algorithm was developed to detect common area of two convex blocks which have potential of being in "face to face" contact. The possibility of the "face to face" contact pattern is examined by one of the most efficient procedures of contact detection in 3D-DDA, the "Main Plane" method. After...
