abstractbackground: although electronic portal imaging devices (epids) have originally developed for positioning verification, they can also be used for dosimetric purposes. in the current work, the dose response of minimum detectable thickness of a scanning liquid filled ion chamber epid, slic-epid, and the variation of transmitted dose with the shift of inhomogeneity inside of phantom was als...

with the increase of communication and financial transaction through internet, on-line signature verification is an accepted biometric technology for access control and plays a significant role in authenticity and authorization in modernized society. therefore, fast and precise algorithms for the signature verification are very attractive. the goal of this paper is modeling of velocity signal t...

Verification is a hard task, but much progress has been achieved recently. Many verification problems have been shown decidable by reducing them to modelchecking finite state transition systems. Verification of infinite state transition systems has achieved tremendous progress too, by showing that many particular cases were themselves decidable, such as timed automata [1] or some forms of pushd...

Abstract Brachytherapy has an excellent clinical outcome for different treatment sites. However, in vivo verification is not performed the majority of hospitals due to lack proper monitoring systems. This study investigates use imaging panel (IP) and photons emitted by a high dose rate (HDR) 192 Ir source track motion obtain some information related patient anatomy. The feasibility this approac...

during the last several years, application of numerical weather prediction models in the country have become common in both research and operations, even though systematic verification of the models’ results using statistical methods has rarely been conducted (sodoudi et al. 2009). this paper aims at comparing the mm5 24-hour precipitation forecasts with the corresponding observations using sta...
