A Simpli ed Model for Light Interaction with Plant Tissue
نویسندگان
چکیده
Rendering techniques currently used in computer graphics enable the generation of very realistic images of a wide range of materials. Despite of the latest achievements in this field, there are still areas, such as biological imaging, open for further investigation. In this paper a simplified model for light interaction with plant tissues is presented. It accounts for the main biological characteristics of these materials needed to preserve their rendering quality, while avoiding undue complexity in order to increase their rendering efficiency. The model’s design and formulation are based on Monte Carlo techniques, and it can be incorporated into global illumination systems without a significant computational overhead. Its accuracy and performance are examined through comparisons with a biologically-based model whose spectral readings have been verified against experimental data for real specimens.

Simpli"ed models of neocortical pyramidal cells preserving somatodendritic voltage attenuation
Simpli"ed models are needed for performing large-scale network simulations involving thousands of cells. Ideally, these models should be as simple as possible, but still capture important electrotonic properties, such as voltage attenuation. Here, we propose a method to design simpli"ed models with correct voltage attenuation, based on camera-lucida reconstructions of neurons. The simpli"ed mod...

A simpli£ed scheme for the investigation of cooperative effects in the quantum jump statistics of small numbers of ¤uorescing atoms and ions in a trap is presented. It allows the analytic treatment of three dipole-dipole interacting four-level systems which model the relevant level scheme of Ba ions. For the latter, a huge rate of double and triple jumps was reported in a former experiment and ...

متن کاملA mathematical analysis of Jones:s site model for spruce budworm infestations
The budworm site model of Jones (1979) is a complicated representation of the interaction between the spruce budworm and the forests of Northeastern Canada, which describes the way in which the budworm population undergoes periodic outbreaks, which lead to severe defoliation and widespread tree mortality. We show how this model can be systematically simpli"ed without gainsaying the essential de...
متن کاملAnalyzing Main and Interaction Effects of Length of Stay Determinants in Emergency Departments
Background Measuring and understanding main determinants of length of stay (LOS) in emergency departments (EDs) is critical from an operations perspective, since LOS is one of the main performance indicators of ED operations. Therefore, this study analyzes both the main and interaction effects of four widely-used independent determinants of ED-LOS. Methods The analysis...
