A crucial aspect in system identification is the assessment of accuracy identified matrices. Stochastic Subspace Identification (SSI) a widely used approach for linear systems from output-only data because it combines high computational robustness and efficiency with estimation accuracy. Practical approaches estimating (co)variance matrices that are using SSI exist case where obtained shift-inv...

Reliable estimates of runoff are required as a part of the information sets that help watershed managers make informed decisions on water resources planning and management. This study was carried out in Shafaroud watershed located in the north of Iran. In order to achieve the best runoff simulation in the study area, first rainfall data of four stations during 1998 to 2011 were collected and co...

This study tried to examine EFL translators’ uncertainty and uncertainty management strategies through employing think aloud procedures. The participants of this study were some MA andBA translators selected from several universities in Iran. To this aim, a proficiency test was firstly administered among the volunteers. Then, think aloud protocol and retrospective interview were used to collect...

make or buy decision is one of the main areas of decision making for managers. transaction cost economics (tce), as an influential economic approach to the theory of the firm, tries to put forward a theoretical framework for this important decision. from tce perspective, the greater the asset specificity, the more the behavioral uncertainty and the more the transaction frequency, the more will ...

many constants and coefficient effect on the modeling results. in many cases, it is possible these constants and coefficients differ from their real values in the environment, but the modeling results adapted with real boundary conditions due to other factors adjustment during modeling. uncertainty analysis is a tool for assessing the effect of uncertainty of various factors on the modeling res...
