background: various variance reduction techniques such as forced detection (fd) have been implemented in monte carlo (mc) simulation of nuclear medicine in an effort to decrease the simulation time while keeping accuracy. however most of these techniques still result in very long mc simulation times for being implemented into routine use. materials and methods: convolution-based forced detectio...

Abstract We produce the first low to mid-frequency radio simulation that incorporates both traditional extragalactic sources as well synchrotron cosmic web emission. The FIlaments & GAlactic RadiO (FIGARO) includes 10 unique 4° × fields, incorporating active galactic nucleii (AGNs), star-forming galaxies (SFGs), and emission out a redshift of z = 0.8 over frequency range 100–1 400 MHz. To d...

The acceptance of the right project which leads to the realization of the set objectives is one of the most important issues in project-oriented companies. Therefore, corporate managers prefer to work on those projects which ensures the achievement of goals such as increasing financial profits or being the top brands in their rivals market. The present  research aimed at introducing  a systemat...

It is now common in the mining industry to deal with several correlated attributes, which need to be jointly simulated in order to reproduce their correlations and assess the multivariate grade risk reasonably. Approaches to multivariate simulation which remove the correlation between attributes of interest prior to simulate and then re-impose the relationship afterward have been gaining popula...

recent studies have indicated that the rate of successful enterprise resource planning (erp) implementation projects is reduced and risk of implementation is increased to the same extent. accordingly, this study provides a model in support of erp implementation using system dynamics approach by behavioral simulation in the vensim software environment. this study is an applied research and due t...
