Abstract Environmental factors and plant architectonics significantly determine its water regime, namely, the content movement through tissues forced by difference in potentials, turgor pressure cells, etc. In turn, cumulative regime affects functioning growth of photosynthesis, and, as a result, plant’s growth. The leaf contributes to formation characterizes contour adaptive system. Neverthele...

This is the second part of a two-part paper developing and validating a structural model to describe the high rate anaerobic digestion of complex wastewater. A full-scale, two-stage hybrid up ̄ow anaerobic reactor treating pig slaughterhouse e‚uent is assessed. Parameters and hydraulics are proposed for this system and validated. Characterisation of the system indicated that in̄uent was a combina...

This paper develops a continuous-time model and controller for the drivetrain dynamics and hydraulics governing the ratio dynamics of a metal V-belt continuously variable transmission (CVT). In developing the drivetrain dynamics, the separate notions of geometric ratio and speed ratio and their relation to each other through the output power efficiency of the CVT are introduced. A data driven m...

Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures.  In the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. The flow hydraulics incl...

Several mathematical models have been developed for applications in the hydraulics of irrigation systems and several performance indicators these are used suggested by literature. Thus, objective this work was to investigate statistical evaluation hydraulics. For this, three case studies which represent typical modeling were assess indicators. A set analyzed: a) difference-based: mean absolute ...

In this paper a concept of an integrated water quality model for a river catchment area is presented. The main focus is directed to the development of a water quality module for rivers. Necessary simplifications for calculation of hydraulics and water quality will be explained. Furthermore, by first simulation results possible applications of the model are presented.
