In a wide range of recommendation systems, self-interested individuals (“agents”) make decisions over time, using information revealed by other agents in the past, and producing that may help future. Each agent would like to exploit best action given current but prefer previous explore various alternatives collect information. A social planner, means well-designed policy, can incentivize balanc...

This study aims to evaluate the status of Iranian gas industry and to formulate appropriate policies in order to attain the objectives of Iran’s Vision 2025. A dynamic model including exploration, production, consumption and demand sub-systems is designed based on the system dynamics approach and is simulated for the period 2010-2025. In this model, factors affecting natural gas exploration, de...

the main problem associated with the traditional approach to image classification for the mapping of hydrothermal alteration is that materials not associated with hydrothermal alteration may be erroneously classified as hydrothermally altered due to the similar spectral properties of altered and unaltered minerals. the major objective of this paper is to investigate the potential of a neuro-fuz...

conclusions io-pth levels should become normal or to drop by at least 80% during successful parathyroidectomy. persistent elevations of io-pth after resection of an abnormal gland dictate the need for bilateral exploration. background we hypothesized that io-pth levels would decline to normal or near normal after successful parathyroidectomy. objectives evaluate efficacy and predictive factor o...
