Large-scale molecular dynamics simulation is performed to study the nano-cutting process of single crystal copper realized by single-point diamond cutting tool in this paper. The centro-symmetry parameter is adopted to characterize the subsurface deformed layers and the distribution and evolution of the subsurface defect structures. Three-dimensional visualization and measurement technology are...

This technical report provides a description and comparison of classical and improved diffusion theory as used for rendering subsurface scattering in computer graphics. We discuss the searchlight problem and describe the diffusion equation and Green’s functions of each diffusion theory. We discuss the commonly used single-depth approximation leading to the diffusion dipole and elaborate on its ...

Several authors have claimed that radiocarbon dates in the Ancient Near East are too early. Herein, a hypothesis that might explain this is presented. Marine degassing of “old” carbon (i.e. 14C-deficient C), induced by upwelling of old subsurface water, has been observed, in modern times, to cause century-scale 14C ages in the surface atmosphere. A review of the Mediterranean Sea post-ice-age c...

An impulse-based single-borehole radar prototype has been developed for well logging. The borehole radar is comprised of subsurface sonde and surface equipment. An armored 7-conductor well logging cable is used to connect subsurface sonde and surface equipment which is well compatible with the other well logging instruments. The performance experiments of the prototype have been conducted in a ...

We will investigate some aspects of Stueckelberg’s work, which have contributed to the development of modern physics. On the one hand, the definition of diffuse boundaries in the calculation of scattering amplitudes will be reviewed, and compared with the other proposals by physicists of that time. On the other hand, the applications of Stueckelberg’s description of a massive vector field in th...

The stability of the lD Luttinger hquid phase of interacting spinless particles (t V mortel) to an on-site diagonal disorder is studied by exact diagonalization of small ID

Detection of subsurface returns from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) on the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite were demonstrated. Despite the coarse range resolution of this aerosol lidar, evidence of subsurface scattering was observed as a delay and broadening of the cross-polarized signal relative to the co-polar...

Analytics is an emerging competency and an evolutionary step beyond traditional reporting and dashboarding, making it both an asset and liability to organizations. Organizations are currently implementing advanced analytic capabilities which require additional considerations not addressed by existing governance frameworks. A distinct analytics governance framework would help address issues surr...

The highway of Yongweol-ri, Muan-gun, south-western part of the South Korean Peninsula, is underlain by the abandoned of subsurface cavities, which were discovered in 2005. These cavities lie at shallow depths with the range of 5∼15 meters below the ground surface. Numerous subsidence events have repeatedly occurred in the past few years, damaging infrastructure and highway. As a result of cont...
