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...

a solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using aspergillus niger atcc 9142. the plackett burman design (pbd) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial ph of substrate, methanol concentration, incubation temperatur...

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...

Water hyacinth ( Eichhornia crassipes ) is one of the potential feedstocks for bioethanol production due to their higher cellulose content. It needs optimization pretreatment remove lignin and release hemicellulose from lignocellulosic complex. Pretreatment was done using sulfuric acid, sodium hydroxide, calcium hypochlorite as soaking agents. Experiment carried out at 121 °C 15 minutes. with 1...

Three common pretreatment processes based on dilute sulfuric acid, dilute sodium hydroxide and heat treatment (autoclaving) followed by enzymatic hydrolysis were evaluated to provide comparative performance data. Among them, the best result was obtained when the pretreatment of rice husk was carried out with 3% of NaOH solution. The pretreatment of rice husk with NaOH substantially increased th...

Abstract We provide a survey of the state art rational verification : problem checking whether given temporal logic formula ϕ is satisfied in some or all game-theoretic equilibria multi-agent system – that is, will exhibit behavior represents under assumption agents within act rationally pursuit their preferences. After motivating and introducing overall framework verification, we discuss key r...
