3D Particle Simulation of Liver Cell Proliferation with Angiogenesis - Partial Hepatic Lobule Formation-
The 6th TSME International Conference on Mechanical Engineering, 16-18 December 2015, at The Regent Cha-am beach Resort, Hua-Hin, Thailand.Recently, the prevalence of viral hepatitis patients has been increasing. Therefore, the reconstruction of liver based on tissue engineering has attracted significant attention. However, the formation or regeneration mechanisms of the liver have not been elucidated; therefore, practical regenerative medicine technology based on tissue engineered liver has not been accomplished. In this study, we propose an analysis model using a Particle Model as the first step. The analysis object is a hepatic lobule. The purpose of this analysis is to elucidate the process of cell proliferation, mechanisms, and states at the micro scale. We used parameters which were obtained by experiments using rats relating to diffusivity, oxygen concentration, and oxygen consumption of a cell. Moreover, we used complex velocity potential of fluid dynamics and obtained a result corresponding to a real hepatic lobule, qualitatively

Contrast Enhancement for Images in Turbid Water
Absorption, scattering, and color distortion are three major degradation factors in underwater optical imaging. Light rays are absorbed while passing through water, and absorption rates depend on the wavelength of the light. Scattering is caused by large suspended particles, which are always observed in an underwater environment. Color distortion occurs because the attenuation ratio is inversely proportional to the wavelength of light when light passes through a unit length in water. Consequently, underwater images are dark, low contrast, and dominated by a bluish tone. In this paper, we propose a novel underwater imaging model that compensates for the attenuation discrepancy along the propagation path. In addition, we develop a robust color lines-based ambient light estimator and a locally adaptive filtering algorithm for enhancing underwater images in shallow oceans. Furthermore, we propose a spectral characteristic-based color correction algorithm to recover the distorted color. The enhanced images have a reasonable noise level after the illumination compensation in the dark regions, and demonstrate an improved global contrast by which the finest details and edges are enhanced significantly
