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...

It is known that the essential ingredients of a Lisp-style unhygienic macro system can be expressed in terms of advanced hygienic macro systems. We show that the reverse is also true: We present a model of a core unhygienic macro system, on top of which a hygiene-compatible macro system can be built, without changing the internals of the core macro system and without using a code walker. To ach...

Introduction: Macro-ergonomics is an important factor that affects behavior, favorable performance and personnel’s efficiency that can cause conformity of employees by increasing labor and efficiency and in result decreasing employees’ stress amount. The aim of the present study was to investigate relationship between Macro-ergonomics and occupational stress in employees working in one casting ...

The paper presents an algorithm for multi-agent strategic modeling (MASM). The method applies domain knowledge and transforms sequences of basic multi-agent actions into a set of strategic action descriptions in the form of graph paths, agent actions, roles and corresponding rules. The rules, constructed by machine learning, enrich the graphical strategic patterns, which are presented in the fo...
