Coffee is the most critical stimulant beverage in the world and represents a significant
source of income in many tropical and subtropical countries. In this paper, a deterministic …

In this paper, an observer for the dynamics of anthracnose disease is proposed based on a
non-spatial model provided by the literature. The model is first improved in order to be more …

In inland fisheries, transporting fishery resource individuals from a habitat to spatially apart
habitat (s) has recently been considered for fisheries stock management in the natural …

Coffee production is an important agricultural activity, in particular in several developing
countries. For decades in Cameroon, coffee has been a proven cash crop and continues to …

This paper aims to tackle an important problem-the optimization of measures applied to fight
disease in one of the most important economically plant cultures: coffee. This is done by …

We present a new impulse control problem of degenerate parabolic Fokker-Planck
equations that govern stochastic growth dynamics of biological resource from the viewpoint …

I am also thanks and grateful to my supervisor, Associate Professor Dr Jugah Bin Kadir, also
a lecturer, in the Department of Plant Protection. I am tremendously thankful and …

Uma das doenças mais comuns na cultura do feijão é a antracnose, que causa diversos
danos na parte aérea, como em folhas e vagens causando principalmente perdas na …

In this work, we apply the nonlinear filtering theory to the estimation of the partially observed
dynamics of anthracnose which is a phytopathology. The signal here is the inhibition rate …
