Flood discharge estimation with different return periods is one of important factors for water structures design and installation. On the other hand, a lot of rivers existing in Iran watersheds have no complete and accurate hydrometric data. In these cases, one of the suitable solutions to estimate peak discharges with different return periods is the regional flood analysis. In this research, 5...
In this paper, the effects of plasma discharge parameters on the nano particles formation process in a plasma enhanced chemical vapor deposition (PECVD) reactor using a model based on equations of ionization kinetics for different active species are studied. A radio frequency applied electric field causes ionization inside the reactor and consequently different reaction schemically active speci...
OBJECTIVE To assess the association between physical fitness and its recovery over time on the one hand, and complications and duration of phases of rehabilitation on the other. DESIGN AND SETTING Prospective cohort study at eight rehabilitation centres. SUBJECTS People with a spinal cord injury were assessed four times: at the start of active rehabilitation (n = 110), three months later (n...
Statistical frequency analysis is the most common procedure for the analysis of flood data at a gauged location thatin first step it is needed to select a model to represent the population. Among them, the central moment has been themost common and widely used, and with the using of computers, the application of the maximum likelihood hasincreased. This research was carried out in order to reco...
