In algal pond used for treating wastewater, a part of the solar radiation (PAR) is by algae photosynthesis, and rest energy wasted. To date, no studies have been conducted that optimize these aspects (wasted heat production) from an operational cost perspective. Therefore, model developed estimation photosynthetically active radiation. Subsequently, derived PAR was utilized in optimization algo...

In Brazil, coffee trees have been included in agroforestry systems, especially owing to climate emergencies and increased demand for specialty coffees. Shading levels inside a multistrata agroforest depend on the design, management and, particularly, development evolution time of system. Understanding these variations over time, as well effects temporary canopy production components, can contri...

We present a mathematical model for a phytoplankton-zooplankton system, based on a predator-prey scheme. The model considers the effects of sinking in the phytoplankton, vertical mixing and attenuation of photosynthetically active radiation (PAR) and ultraviolet radiation (UVR) in the water column. In a first approach, the model was studied under conditions of average PAR irradiance and shows f...

This paper describes the implementation of a physical and mathematical approach to design a simple 2-dimensional algorithm dedicated to the interpretation of data collected by MISR. One dimension of information fully exploits the spectral information in the blue, red and near-infrared bands while the other dimension capitalizes on the multiangular capability of MISR to assess the anisotropic be...
