Affected by customers’ lack of experiences and personal preferences, the importance of customer demand as 0 by only using Rough Set method frequently occurs. Existing methods could not determine this importance of indicators, so it is usually deleted. A new method combining Rough Set and Data Envelopment Analysis (DEA) to determine importance of customer demand in Quality Function Deployment (Q...

most regions of iran are confronted with inadequate supply and excessive demand of water in agriculture sector mainly resulting from a high difference between water providing cost and its price. coping with such a challenge needs to determine the water price based on the economic principles and its value in agricultural production. the aim of this study was to determine the economic value of th...

t i o Measurement of absolute myocardial blood flow (MBF) and coronary flow reserve (CFR) is of great importance clinically. To make such measurements quantitatively, one must also measure the arterial input function (AIF). Many studies, including the one reported by Vasquez et al. (1) in this issue of iJACC, which focuses on rubidium-82 (Rb), have sought optimal ways to measure the AIF for a v...
