Determination of Correction Coefficient of the Sterlling's Formula by Mohamadjavad Tahmasebi Biragani, Mohammad Ali Behrooz, Mohammad Hosseini, Fatemeh Ghahremani, Fatemeh Seyf

“…Subjects and Method: By measuring the amount of Sc for square fields,the variation of Sc in terms of square field size was plotted, the relationship between Sc and field size was determined by Exel software.By this relation, the equivalent square fields for rectangular fields attained and average Vadash's factor ) was calculated for them.A selection of different values around this average, for every energy (6MV and 18MV) the value of A were determined, finally A that total variance around the average was minimum is desirable for Vadash,s factor.Results:Vadash's factor for energy 6MV and 18MV Linac Varian 2100 CD are obtained 2.14 and 2.29 respectively.Conclusion: According to the collimator exchange effect, the Sterlling's formula needs a correction by applying the physical analysis of Sc for various energy, this correction is extractable.…”

SIMULATION RESULTS OF SPECKLE SUPPRESSION IN RADAR WITH SYNTHETIC APERTURE by R. N. Akinshin, V. L. Rumyantzev, A. V. Peteshov

“…The disadvantage of (RLI) radar images obtained with a single-channel radar station is the presence of speckle that leads to intensity flashes increasing the number of false alarms when detecting point targets. Therefore, the detection and target distinguishing by their reflective capability (using the energy characteristics of the signal) is not effective enough. …”
