This letter presents an algorithm for reducing measurement uncertainty of one physical quantity when oversampling measurements two quantities with correlated noise. The assumes that the aleatoric in both follows a Gaussian distribution and relies on sampling faster than it is possible measurand (the true value we are trying to measure) change (due system thermal time constant) calculate paramet...
One of the most important decisions companies should make in the process of selecting strategies to enter foreign markets is the extent to which they intend to control themselves and the extent of such international activities they choose to leave to other parties. Having comprehensively reviewed the related literature, the following 12 variables explaining the degree of tendency among compan...
in recent years, decrease in depth of uromia lake, has resulted in higher increase of salinity threat in agricultural lands around the lake. the aims of this study were 1- investigation of the spatial changes in soil salinity using the bayesian maximum entropy method (bme); 2- prediction of the boundary between saline and agricultural lands; and 3- assessment of the uncertainty involved with sa...
This chapter surveys empirical models of market structure. We pay particular attention to equilibrium models that interpret cross-sectional variation in the number of firms or firm turnover rates. We begin by discussing what economists can in principle learn from models with homogeneous potential entrants. We then turn to models with heterogeneous firms. In the process, we review applications t...
Data envelopment analysis (DEA) is one of non-parametric methods for evaluating efficiency of each unit. Limited resources in healthcare economy is the main reason in measuring efficiency of hospitals. In this study, a bootstrap interval data envelopment analysis (BIRDEA) is proposed for measuring the efficiency of hospitals affiliated with the Hamedan University of Medical Sciences. The propos...
