We motivate and analyze a reaction-advection-di usion model for the dynamics of a phytoplankton species. The reproductive rate of the phytoplankton is determined by the local light intensity. The light intensity decreases with depth due to absorption by water and phytoplankton. Phytoplankton is transported by turbulent di usion in a water column of given depth. Furthermore, it might be sinking ...

Background. Athletes’ performance in sporting events is influenced by several factors. One of them is how fair the compensation system is implemented. The proper compensation will motivate the athlete to perform better. Otherwise, it will be a loss for the team. Objectives. The purpose of this study was to determine the effect of compensation on the sports achievements of South Sulawesi athlet...

The goal of radiation therapy is to give as much dose as possible to the target volume of tissue and avoid giving any dose to a healthy tissue. Advances of the digital control allow performing accurate plans and treatments. Unfortunately, motion compensation during the treatment remains a considerable problem. Currently, a combination of the different techniques, such as gating (restricting mov...

The fairness of the utilization cultivated land resources is essential for balanced development region, but there are few researches to analyze it. Against background urgent need farmland protection and ecological compensation, this paper takes as research object uses a three-dimensional footprint model account natural capital stock flow in Beijing-Tianjin-Hebei region from 2009 2016 terms brea...

Development work leading to emittance-compensated symmetric emittance and asymmetric emittance RF photoinjectors is discussed. A mature design for a symmetric emittance photoinjector is described, and current work leading to an asymmetric design is detailed. An experimental program to characterize both injectors and to explore the physical mechanism of emittance compensation using the facilitie...

An object-based coding scheme is proposed for the coding of the right channel of a stereoscopic image sequence, using motion and disparity information. A multiresolution block-based motion estimation approach is used for initialization, while disparity estimation is performed using a pixel-based hierarchical dynamic programming algorithm. A split and merge segmentation procedure based on both 3...

SUMMARY In modern geodynamics, isostasy can be viewed either as the static equilibrium of crust that minimizes deviatoric stresses, or a dynamic process resulting from viscous relaxation non-hydrostatic crustal shape. Paper I gave general formulation Airy an elastic loading problem solved with Love numbers, and applied it to case minimum stress isostasy. this sequel, same framework is used stud...

The background of this research is that to carry out teaching and learning activities in a school, an educator needed. Educators are the main determinants success process carried out. performance teacher can be well reflected if results teacher's appreciated. Compensation one external factors improve performance. One things provision compensation form salaries, bonuses, types allowances other f...
