purpose: to evaluate the role of active uveitis on refractive errors changes. methods: a cohort single group study was conducted on patients with acute or recurrent uveitis. cyclorefraction was performed in both phases of active and quiescent. sphere, cylinder and sphere equivalent power were compared in active and quiescent phases and analyzed statistically. results: sixty-six patients (eighty...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
The purpose of this study was to examine the effect of self-control feedback on the learningof generalized motor program and parameters during physical and observational practice. Participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked and instructor KR) groups. They practiced a sequential timing task. The task required participants to press four k...
Approximate Dynamic Inversion has been established as a method to control minimum-phase, nonaffine-incontrol systems [1]. In this report, we re-state the main results of [1], clarify some minor notational errors, and prove the same results in an expanded form. In the large, the main results of [1] still stand. The development follows [1] closely, and no novelty is claimed herein. The purpose of...
Phase-measurement interferometry (PM!) techniques enable quantitative measurements to be performed in optical testing, holographic interferometry, and speckle metrology. This paper will present results of error analyses of the most common errors in phase-measurement techniques. These errors include miscalibrated and nonlinear phase shifters, detector nonlinearities, detection quantization, vibr...
Typographical data entry errors and incomplete documents, produce imperfect records in real world databases. These errors generate distinct records which belong to the same entity. The aim of Approximate Record Matching is to find multiple records which belong to an entity. In this paper, an algorithm for Approximate Record Matching is proposed that can be adapted automatically with input error...
the purpose of this study was to examine the effect of self-control feedback on relative and absolute timing through observational and physical practices. participants (n=90) were randomly assigned to physical and observational practice (self-control, yoked, and instructor kr) groups. they practiced a sequential timing task, which required participants to press four keys (2, 6, 8, and 4) respec...
