Through the analysis of the existing multi-motor control scheme, proposed a multi-motor control system program constituted by the PC ,Siemens PLC, inverter, induction motor etc, designed the overall control system; through the analysis and the characteristics of multi-motor synchronous control and the fuzzy PID control to determine the synchronization control scheme, proposed a control strategy...

Recently there has been an increase in the use of spectral methods for the analysis of experimental data. These analytical methods allow the study of interactions between simultaneously recorded signals and are particularly suited to the study of systems displaying rhythmic behaviour. A useful parameter in this context is the coherence function which provides a bounded measure of linear associa...

Background: Toddlers with celiac disease are at risk of developmental delay due to frequent hospitalization and food deprivation. But an appropriate program to improve development of these children does not exist. Aim: Determination of the effect of a developmental stimulation program on development of toddlers’ fine motor skills. Methods: This clinical trial conducted on 50 eligible 1-3 year-o...

The study of the neural basis of motor patterns that underlie wavelike behaviors such as undulatory swimming has contributed to our general understanding of coordination in the nervous system. Numerous studies have shown that the isolated nervous system is capable of producing rhythmic motor output in the absence of sensory feedback (Marder and Calabrese 1996). In addition, in many cases these ...

In prior work (Corriveau et al., 2007), we showed that children with speech and language impairments (SLI) were significantly less sensitive than controls to two auditory cues to rhythmic timing, amplitude envelope rise time and duration. Here we explore whether rhythmic problems extend to rhythmic motor entrainment. Tapping in synchrony with a beat has been described as the simplest rhythmic a...

Rhythmic motor patterns are thought to arise through the cellular properties and synaptic interactions of neurons in central pattern generator (CPG) circuits. Yet, when examining the CPG underlying the rhythmic escape response of the opisthobranch mollusc, Tritonia diomedea, we found that the cycle period of the fictive swim motor pattern recorded from the isolated nervous system was not altere...
