The dynamics of two mutually coupled chaotic diode lasers are investigated experimentally and numerically. By adding self-feedback to each laser, stable isochronal synchronization is established. This stability, which can be achieved for symmetric operation, is essential for constructing an optical public-channel cryptographic system. The experimental results on diode lasers are well described ...

most researches in the felid of human resource development by means of personal development plan has focused on education and health industries. the aim of this research is to explain human resource development process in order to gain a better understanding and identifying factors affecting this process in project- based organizations. to this end, by adopting grounded theory methodology, data...

Skeleton data carries valuable motion information and is widely explored in human action recognition. However, not only the but also interaction with environment provides discriminative cues to recognize of persons. In this paper, we propose a joint learning framework for mutually assisted ''interacted object localization'' ''human recognition'' based on skeleton data. The two tasks are seriali...

We consider small network models for mutually delay-coupled systems which typically do not exhibit stable isochronally synchronized solutions. We show analytically and numerically that for certain coupling architectures which involve delayed self-feedback to the nodes, the oscillators become isochronally synchronized. Applications are shown for both incoherent pump-coupled lasers and spatiotemp...

the aim of this study was to determine the interactional effects of various video shows (skilled and self-model) and feedback type on performance and learning of dart throwing skill. 90 volunteers were randomly divided into 6 groups including self-control, experimenter control and yoked feedback that received either skilled model or self-model. three groups who watched the skilled model observe...

this study aimed at investigating the effect of the type of feedback and practice on the acquisition of parameter index. for this purpose, 8 groups (each 12 subjects) were formed: constant practice group with self–controlled feedback, constant practice group with yoked feedback (yoked group), blocked practice group with self–controlled feedback, blocked practice group with yoked feedback, rando...

A necessary and sufficient condition is given for assuring stability of a single-input single-output (SISO) feedback control system when several controls laws are averaged together. Such a situation is encountered when several controllers are designed for different operating conditions which are not mutually exclusive. The special case of using fixed (as opposed to time-varying) weightings for ...

We present a result on stabilization of strict feedback systems with unknown disturbances based on the so-called twisting algorithm, a second-order sliding mode controller for the double integrator. The novelty of the note relies in the stability analysis of the closed-loop system and the relaxation of stability conditions (we do not assume boundedness of trajectories). The proof of the main re...
