In aerospace engineering and industry, control tasks are often of a periodic nature, while repetitive control is especially suitable for tracking and rejection of periodic exogenous signals. Because of limited research effort on nonlinear systems, we give a survey of repetitive control for nonlinear systems in this paper. First, a brief introduction of repetitive control is presented. Then, aft...

We present a new visual programming language and environment that serves as a form of feedback and representation in a Programming by Demonstration system. The language diiers from existing visual languages because it explicitly represents data objects and implicitly represents operations by changes in data objects. The system was designed to provide non-programmers with programming support for...

The classification of various document images is considered an important step towards building a modern digital library or office automation system. Convolutional Neural Network (CNN) classifiers trained with backpropagation are considered to be the current state of the art model for this task. However, there are two major drawbacks for these classifiers: the huge computational power demand for...

assessment of embryo quality in order to choose the embryos that most likely result in pregnancy is the critical goal in assisted reproductive technologies (art). the current trend in human in vitro fertilization/embryo transfer (ivf/et) protocols is to decrease the rate of multiple pregnancies after multiple embryo transfer with maintaining the pregnancy rate at admissible levels (according to...

Background: Prolonged inhibition of acetylcholine esterase may lead to the intermediate syndrome. Neuromuscular junction (NMJ) dysfunction has been shown with repetitive nerve stimulation (RNS). Subclinical NMJ dysfunction may also occur. We aimed to examine the NMJ function following acute organophosphorus (OP) poisoning by using exercise modified slow RNS. Methods: A cohort study was conducte...

OBJECTIVE The aims of this study were to investigate the effects of low-frequency repetitive transcranial magnetic stimulation on patients with visual spatial neglect and to explore the potential mechanisms of visual spatial neglect. METHODS A total of 14 patients with prior stroke and visual spatial neglect were divided into a control group and a treatment group. The treatment group was expo...

Background: The first purpose of this study was to investigate the rate of oral and laryngeal Diadochokinesis (DDK) in Multiple Sclerosis (MS) patients in comparison with healthy people. The second goal was to determine if DDK rate has any relationship with the disease progression. Methods: In this cross-sectional study, two groups were enroll...
