Regionalizing nonparametric models of precipitation amounts on different temporal scales [PDF]
Hydrology and Earth System Sciences, 2017 Parametric distribution functions are commonly used to model precipitation amounts corresponding to different durations. The precipitation amounts themselves are crucial for stochastic rainfall generators and weather generators.

THE SIMULATION OF HYDRAULIC SYSTEMS
IFAC Proceedings Volumes, 1980 Abstract This paper describes progress towards a general purpose simulation language for hydraulic systems. The aim of the language is to allow engineers with no formal skill in computer programming or mathematical modelling to examine the dynamic or steady state conditions in systems at the design stage.

The Effect of Hydraulic Accumulator on the Performance of Hydraulic System
Journal of Engineering, 2023 The purpose of this paper is to depict the effect of adding a hydraulic accumulator to a hydraulic system. The experimental work includes using measuring devices with interface to measure the pressure and the vibration of the system directly by computer so as to show the effect of accumulator graphically for real conditions, also the effects of ...

Indirect downscaling of hourly precipitation based on atmospheric circulation and temperature [PDF]
Hydrology and Earth System Sciences, 2013 The main source of information on future climate conditions are global circulation models (GCMs). While the various GCMs agree on an increase of surface temperature, the predictions for precipitation exhibit high spread among the models, especially in ...
