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...

We analyzed individual motor units during electrically elicited cramp contractions with the aim of characterizing the variability and degree of common oscillations in their discharges. Intramuscular and surface electromyographic (EMG) signals were detected from the abductor hallucis muscle of 11 healthy subjects (age 27.0+/-3.7 yr) during electrically elicited cramps. In all, 48 motor units wer...

26 Anatomical and pharmacological studies have shown that the lateral superior olive (LSO) 27 receives inputs from a number of sources, and that LSO cells can alter the balance of their own 28 excitatory and inhibitory drive. It is thus likely that the ongoing sound-evoked responses of LSO 29 cells reflect a complex interplay of excitatory and inhibitory events, which may be affected by 30 anes...

The transient electromagnetic disturbance generated by arcing discharge between the pantograph and catenary can pose a significant risk to safe operation of electrified railways. In order better comprehend its properties, pantograph–catenary generating device is designed simulate phenomenon with moving electrodes in this experimental investigation. effects applied voltage, gap distance, relativ...

The effects of impervious area, septic leach-field effluent, and a riparian wetland on runoff generation were studied in three small (0.38–0.56 km) headwater catchments that represent a range of suburban development (high density residential, medium density residential, and undeveloped) within the Croton River basin, 70 km north of New York City. Precipitation, stream discharge, and groundwater...

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 Nash's cascade model that is simple and efficient model for simulating hydrological response in watersheds, catchment behavior is considered same as n linear reservoirs with k storage coefficient. In this context, the accuracy of different methods of estimating the Nash model parameters (n and k) including moment, experimental Nash formula, Han’s graphical, time to peak-time to inflection po...
