A new approach is proposed to the calibration of photodetectors and the determination of the absolute value of the quantum efficiency of photon-counting photomultipliers using entangled-photon pairs. It is based on a new single-photodetector technique and a special modulation of the entangled-photon flux. The absolute values of the quantum efficiency have been determined for several photon-coun...

this paper studies the technical efficiency of 12 branches of saman bank over the period 1387-88, relating it to the composition of staff by sex, the ratio of fixed assets to total assets, the age of the branches and the geographic ranking in development indicators of the city where the branch is located in. data envelopment analysis is used to determine the efficiency of branches. the average ...

There is a need for knowledge, experience, laboratory, materials, and time to conduct chemical experiments. The results depend on the process and are also quite costly. For economic and rapid results, chemical processes can be modeled by utilizing data obtained in the past. In this paper, an artificial neural network model is proposed for predicting the removal efficiency of...

BACKGROUND Heat and moisture exchangers (HMEs) are commonly used in chronically tracheostomized spontaneously breathing patients, to condition inhaled air, maintain lower airway function, and minimize the viscosity of secretions. Supplemental oxygen (O2) can be added to most HMEs designed for spontaneously breathing tracheostomized patients. We tested the efficiency of 7 HMEs designed for spont...

One of the most important topic that consider in recent years by researcher is absolute value equation (AVE). The absolute value equation seems to be a useful tool in optimization since it subsumes the linear complementarity problem and thus also linear programming and convex quadratic programming. This paper introduce a new method for solving absolute value equation. To do this, we transform a...

This paper addresses the question of whether the findings of behavioral economics imply that techniques used in cost-benefit analysis should be modified. The findings of behavioral economics considered include the status-quo effect, loss-aversion, overconfidence and hyperbolic discounting. These behavioral phenomena do indeed imply that concepts from cost-benefit analysis such as consumer surpl...
