Experimental methods are commonly used for patient-specific IMRT delivery verification. There are a variety of IMRT QA techniques which have been proposed and clinically used with a common understanding that not one single method can detect all possible errors. The aim of this work was to compare the efficiency and effectiveness of independent dose calculation followed by machine log file analy...

Abstract Purpose: Advanced radiation therapy techniques use small fields in treatment planning and delivery. Small have the advantage of more accurate dose delivery, but with cost some complications dosimetry. Different calculation algorithms imported various systems (TPSs) which each them has different accuracy. Monte Carlo (MC) simulation been reported as one methods for calculating distribut...

Harmonic resonances are part of the power quality (PQ) problems electrified railways and have serious consequences for continuity service integrity components in terms overvoltage stress. The interaction between traction stations (TPSs) trains that causes line is briefly reviewed, showing dependence on infrastructure conditions. objective monitoring resonance conditions at onboard pantograph in...

The present paper is devoted to the development of a kind of spectral meshless radial point interpolation (SMRPI) technique in order to obtain a reliable approximate solution for buckling of nano-actuators subject to different nonlinear forces. To end this aim, a general type of the governing equation for nano-actuators, containing integro-differential terms and nonlinear forces is considered. ...

Scalability is one of the utmost nonfunctional requirement server applications, because it maintains an effective performance parallel to large fluctuating and sometimes unpredictable workload. In order achieve scalability, thread pool system (TPS) has been used extensively as a middleware service in applications. The size most significant factor, that affects overall servers. Determining optim...

Terpene synthases (TPS) catalyze the cyclization of acyclic prenyl diphosphate precursor and are responsible for abundance natural product terpene in nature. The biosynthesis terpenoid by nonseed plant TPS is not well understood due to highly dynamic feature reaction unavailability enzyme structure. Here we discovered a class I JeST4 from Jungermannia exsertifolia elucidated its catalytically a...
