Calibration of model is critical for hydrologic modeling of large watersheds in a mountain watershed. In this study Soil and Water Assessment Tool (SWAT) used to comparison a single-site calibration procedure that employed streamflow measurement at outlet of watershed to a multi-site calibration method that used streamflow measurements at three stations (Galinak, Joestan and Dehdar). Results sh...

In order to elucidate the effect of galactic cosmic rays on cloud formation, we investigate the optical response of marine aerosols to Forbush decreases – abrupt decreases in galactic cosmic rays – by means of modeling. We vary the nucleation rate of new aerosols, in a sectional coagulation and condensation model, according to changes in ionization by the Forbush decrease. From the resulting si...

the application of a flight simulator with six degree of freedom (6dof)) in design and analysis of rocket systems is essential. the calibration of a 6dof flight simulator is a challenging problem. this paper focuses on the calibration of a flight simulator and intends to answer the following questions: 1) does experimental design have significant impact on calibration quality? if so, which expe...
