The aim of this study was to investigate pre-service physical education teachers’ self-assessment of their competent levels in achieving the national standards for beginning physical education teachers (National Association for Sport and Physical Education (NASPE), 1995). One hundred seventy–three pre-service teachers in 10 physical education teacher education programs completed the Achieving t...

We explore the practical limits on throughput imposed by timing in a long, self-timed, circulating pipeline (ring). We consider models with both fixed and random delays and derive exact results for pipelines where these delays are fixed or exponentially distributed random variables. We also give relationships that provide upper and lower bounds on throughput for any pipeline where the delays ar...

Abstract: The paper addresses the problem of output feedback guaranteed cost controller design for NCSs with time-delay and polytopic uncertainties. By constructing a new parameter-dependent Lyapunov functional and applying the free-weighting matrices technique, the parameter-dependent, delay-dependent design method will be obtained to synthesize a PID controllers achieving a guaranteed cost su...

Multielectrode recordings have revealed zero time lag synchronization among remote cerebral cortical areas. However, the axonal conduction delays among such distant regions can amount to several tens of milliseconds. It is still unclear which mechanism is giving rise to isochronous discharge of widely distributed neurons, despite such latencies. Here, we investigate the synchronization properti...

Scattering dynamics are examined for Gaussian and non-Gaussian wave packets with identical momentum densities. Average arrival time delays, dwell times, phase delays calculated scattering from a square barrier, it is shown that the exhibit different average than packets. These differences result non-linear terms in function of packets, which alters self-interaction times Control delay can be ac...

Human standing balance relies on self-motion estimates that are used by the nervous system to detect unexpected movements and enable corrective responses adaptations in control. These must accommodate for inherent delays sensory motor pathways. Here, we a robotic simulate human about ankles anteroposterior direction impose sensorimotor into control of balance. Imposed destabilized standing, but...

In the information-theoretic setting, where adversaries have unlimited computational power, the fundamental cryptographic primitive Oblivious Transfer (OT) cannot be securely achieved if the parties are communicating over a clear channel. To preserve secrecy and security, the players have to rely on noise in the communication. Noisy channels are therefore a useful tool to model noise behavior a...

In this paper we study the well-posedness of different models of population of leaky integrate-and-fire neurons with a population density approach. The synaptic interaction between neurons is modeled by a potential jump at the reception of a spike. We study populations that are self excitatory or self inhibitory. We distinguish the cases where this interaction is instantaneous from the one wher...
