This work considers forced vibrations in a rotating structure consisting of two-stage spur gear system with coexisting defects, specifically pitting and cracking. Numerical simulations experimental analysis various scenarios the operation were conducted using RPM–Frequency mapping technique. To identify fault characteristics, performed assumed had been misadjusted by combination cracking on tee...

In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. Unfortunately, despite the advantages of chaotic systems, Such as, noise-like correlation, easy hardware implementation, multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena and potential communication confidence due to the very dynami...

The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...

Abstract Flexible robots with controllable mechanisms have advantages over common tandem in vibration magnitude, residual time, working speed, and efficiency. However, abnormal can sometimes occur, affecting their operation. Traditionally only simple are considered studying vibration, omitting reference to important chaotic phenomena caused by the flexibility of mechanism rod. In order better u...

Molding processes are among the most important in manufacture of reinforced concrete structures. Vibration and shock-vibration technologies for mixtures compaction products molding have greatest distribution construction industry. Therefore, issues optimizing vibration modes, correct choice equipment do not lose their relevance. The article discusses dynamical behavior a shock-vibrational low-f...

OBJECTIVES/HYPOTHESIS Evaluate the effects of asymmetric superior laryngeal nerve stimulation on the vibratory phase, laryngeal posture, and acoustics. STUDY DESIGN Basic science study using an in vivo canine model. METHODS The superior laryngeal nerves were symmetrically and asymmetrically stimulated over eight activation levels to mimic laryngeal asymmetries representing various levels of...

chaotic systems are nonlinear dynamic systems, the main feature of which is high sensitivity to initial conditions. to initiate a design process in fuzzy model, chaotic systems must first be represented by t-s fuzzy models. in this paper, a new fuzzy modeling method based on sector nonlinearity approach has been recommended for chaotic systems relating to initial condition variations using the ...
