Formula-based analysis of communication links with time-varying channels and adaptive equalizers is not always tractable Monte Carlo simulation must be used to obtain bit error rate (BER) estimates of the system. Conventional Monte Carlo simulation will not provide estimates for low BER's due to excessive run time. Although importance sampling (IS) techniques offer the potential for large speed...
An adaptive memory method for accurate and efficient computation of the Caputo fractional derivative
Abstract A fractional derivative is a temporally nonlocal operation which computationally intensive due to inclusion of the accumulated contribution function values at past times. In order lessen computational load while maintaining accuracy derivative, novel numerical method for Caputo proposed. The present adaptive memory significantly reduces requirement storing time points and also improves...
Objective: The purpose of this research was to investigate the effectiveness of Shaw’s method to enhance working memory of first-grade students with Borderline Intellectual Functioning Method: A single subject method with multiple baseline design (MBD) research methodology was used. In this regard, among the first grade elementary school students in Isfahan in 2015-2017, four students with B...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
this paper presents a new centralized adaptive method under frequency load shedding. sometimes, after initial frequency drop following severe disturbances, although the system frequency returns to its permissible value, however, the system might become unstable due to voltage problems. in this regard, the paper proposes a new centralized adaptive load shedding method to enhance the voltage stab...
Introduction: Most of our knowledge regarding the link between opioid dependence and poor cognitive functioning is derived from cross sectional studies.This longitudinal study measured the change in memory functioning following complete abstinence among individuals with heroin dependence. Methods: Using a before-after design,this study followed 30 adults ...
some numerical and experimental investigations are made on the performance of five different hyperelastic constitutive models (second order polynomial, yeoh, arruda-boyce, ogden and marlow) in tension and compressionmodes. first, the results of the tensile and compression tests on a rubber sample were used to determine the parameters of the models by curve fitting methods. next, by using an alg...
aim and background: it has been shown in several studies that, students with mathematics learning disabilities have memory problems. this research compares memory profile of students with and without mathematics learning disabilities. methods and materials: the design of research was cross-sectional with causal-comparative method. the statistical population were 3 rd grade student boys in isfah...
