This paper investigates the use of a new sliding mode control for output voltage regulation boost converter under parametric uncertainties load resistance and input voltage. Owing to fact that proposed scheme employs adaptation law; therefore, apriori knowledge about upper bound value is not required while selecting controller gains. Moreover, stability analysis closed-loop system guarantees fi...

We evaluate the relative importance of uncertainty related to parameters characterizing partially saturated groundwater flow on head and gravity changes associated with pumping tests taking place in homogeneous heterogeneous porous media. frame our study a Global Sensitivity Analysis setting assess way imperfect knowledge such influences probability distribution (pdf) gravimetric variations rec...

coastal lagoons are complex ecosystems exhibiting a high degree of non-linearity in the distribution and exchange of nutrients dissolved in the water column due to their spatio-temporal characteristics. this factor has a direct influence on the concentrations of chlorophyll-a, an indicator of the primary productivity in the water bodies as lakes and lagoons. moreover the seasonal variability in...
