This paper compares different types of simulated draws over a range of number of draws in generating Bayesian efficient designs for stated choice (SC) studies. The paper examines how closely pseudo Monte Carlo, quasi Monte Carlo and Gaussian quadrature methods are able to replicate the true levels of Bayesian efficiency for SC designs of various dimensions. The authors conclude that the predomi...

This paper will try to look into the two important methods for the calculation of Value at Risk (VaR) for non linear portfolio using Monte Carlo Simulation method. The two techniques Closed form VaR and Multilevel Monte Carlo VaR for valuing the derivative portfolio are explained in details. In case of multilevel Monte Carlo simulation, it has been found that with decrease in the number of inne...

We provide the first direct calculation of Knudsen layer (KL) thickness in rarefied gas flows based on ballistic molecular motions simulation Monte Carlo simulations. Calculations reproduce a linear relation between KL and mean free path (MFP) gas, which agrees with classical kinetic theory statement. The ratio MFP is only function model at slight flow gradients. However, high gradient surface ...

– The Wigner equation taking into account both the non-local potential operator and a scattering operator represents a suitable physical model for carrier transport in nano structures. In this paper a new Monte Carlo method is proposed for the solution of the stationary Wigner equation. Scattering can be included at the level of the semi-classical Boltzmann scattering operator, whereas coherent...

introduction after the publication of task group number 43 dose calculation formalism by the american association of physicists in medicine (aapm), this method has been known as the most common dose calculation method in brachytherapy treatment planning. in this formalism, the water phantom is introduced as the reference dosimetry phantom, while the attenuation coefficient of the sources in the...

This paper compares different types of simulated draws over a range of number of draws in generating Bayesian efficient designs for stated choice studies. The paper examines how closely pseudo Monte Carlo, quasi Monte Carlo and polynomial cubature methods are able to replicate the true levels of Bayesian efficiency for SC designs of various dimensions. The authors conclude that the predominantl...

Background: Stereotactic radiosurgery is an important clinical tool for the treatment of small lesions in the brain, including benign conditions, malignant and localized metastatic tumors. A dosimetry study was performed for Elekta ‘Synergy S ’ as a dedicated Stereotactic radiosurgery unit, capable of generating circular radiation fields with diameters of 1-5 cm at isocentre using the BEAM/EGS4...

UAV formation keeping is an important research element due to its cooperative control. This study proposes a passive positioning model for UAVs based on the Monte Carlo strategy and provides trajectory programming decision scheme predicted calculation of deviated predefined endpoint locations, effectively improving efficiency performing formation-keeping tasks during flight. Then, simulation af...

The dose calculation accuracy of a commercial pencil beam IMRT planning system is evaluated by comparison with Monte Carlo calculations and measurements in an anthropomorphic phantom. The target volume is in the right lung and mediastinum and thus significant tissue inhomogeneities are present. The Monte Carlo code is an adaptation of the MCNP code and the measurements were made with TLD and fi...
