In this study, synchronization phenomena observed in van der Pol oscillators coupled by a timevarying resistor are investigated. We realize the time-varying resistor by switching a positive and a negative resistor periodically. By carrying out circuit experiments and computer calculations, interesting synchronization phenomena can be confirmed to be generated in this system. Namely, the synchro...

Recently, many vehicle manufacturers started to invest in new technology reduce the emission produced by their engines. Due regulations that become more stringent and rising demand for highly efficient vehicles, technologies were introduced achieve demand. One of gain popularity modern vehicles is applying force induction systems such as turbocharging supercharging engine. By using turbocharger...

in this paper, an anomaly detection method in cluster-based mobile ad hoc networks with ad hoc on demand distance vector (aodv) routing protocol is proposed. in the method, the required features for describing the normal behavior of aodv are defined via step by step analysis of aodv and independent of any attack. in order to learn the normal behavior of aodv, a fuzzy averaging method is used fo...

Nanophononic materials are promising to control the transport of sound in GHz range and heat THz range. Here we interested influence a dendritic shape inclusion on acoustic attenuation. We investigate Finite Element numerical simulation transient propagation an wave-packet 2D nanophononic with circular or inclusions periodically distributed matrix. By measuring penetration length, diffusivity, ...

This paper extends previous large-eddy simulations of the convective boundary layer over a surface with a spatially varying sensible heat flux. The heat flux variations are sinusoidal and onedimensional. The wavelength is 1500 or 4500 m (corresponding to 1.3 and 3.8 times the boundarylayer depth. respectively) and the wind speed is 0. 1 or 2 m sI. In every case the heat flux variation drives a ...
