Total error is often calculated as a combination of random error and fixed bias. However, the specific protocols used to estimate random error and fixed bias are themselves variable factors that can affect the estimate of total error. We refer to biases such as assay drift, sample-to-sample carryover, and reagent carryover as examples of fixed biases that are protocol-specific and distinguish t...
بر اساس پخش و پراکندگی چینه شناسی روزنبران پلانکتونیک شناسایی شده از برش مورد پژوهش 9 بیوزون شناسایی و معرفی شد که منطبق با بایوزون های استاندارد جهانی در قلمرو تتیس بوده و به ترتیب ازپایین به بالا شامل : بیوزون 1)dicarinella concavata interval zone (سانتونین پسین) بیوزون 2) dicarinella asymetrica total range zone ( کامپانین میانی) بیوزون 3) globotruncanita elevata interval zone ( کامپانین پ...
This study evaluates the performance of the linear first-order Volterra model for simulating nonlinear rainfall-runoff process. For this end, fifteen storm events over the Navrood River basin were collected. 70% and 30% of the events were used to calibrate and test the suitability of the model. Finally, the performance of the model was compared with the artificial neural networks (multilayer pe...
introduction: medication errors are among the most serious health errors threatening patient safety in all countries, with major impacts on public health. midwives as members of healthcare systems are prone to such errors. therefore, in this study, we aimed to determine medication errors and the contributing factors among midwives working in maternity units of mashhad university of medical scie...
this paper presents an accurate differential global positioning system (dgps) using multi-layered neural networks (nns) based on the back propagation (bp) and imperialistic competition algorithm (ica) in order to predict the dgps corrections for accurate positioning. simulation results allowed us to optimize the nn performance in term of residual mean square error. we compare results obtained b...
