摘要:Many researchers introduce schemes for designing multistable systems by coupling two identical systems. In this paper, we introduce a generalized scheme for designing multistable systems by coupling two different dynamical systems. The basic idea of the scheme is to design partia...

摘要:We present the optical properties of rare earth (RE)-doped \(\hbox {Al}_2\hbox {O}_3\) thin films and discuss their possible use in applications like gate dielectric material and in coating industry. Aluminum oxide films doped with RE elements such as Ce, Nd, Gd, and Dy are ...

摘要:CdSe:Mn thin films were grown by chemical bath deposition. The pH of the solution was maintained at 11. Dry films so obtained were annealed in vacuum ( \(10^{-1}\,\hbox {Torr}\) ) for about 2 h at \(400^{\circ }\hbox {C}\) . The annealed samples were subjected to morphologic...

摘要:In order to further understand a self-exciting Faraday disc dynamo (Hide et al , in Proc . R . Soc . A 452 , 1369 1996 ), showing chaotic attractors with very complicated topological structures, we present codimension one and two (degenerate) Hopf bifurcations and prove the exist...

摘要:From a generic transformation, a (3 \(+\) 1)-dimensional nonlinear Schrödinger equation with spatially modulated nonlinearity is studied and exact spatiotemporal soliton cluster solutions are derived. When the azimuthal parameter \(m = 0\) , Gaussian solitons are constructed...

摘要:High-power (∼ 100 kW) industrial electron linear accelerators (linacs) are used for irradiations, e.g., for pasteurization of food products, disinfection of medical waste, etc. We propose that high-power electron beam from such an industrial linac can first pass through an u...

摘要:Using the residual symmetry approach, we propose a complex extension of the scaling ansatz on the neutrino Majorana mass matrix \(M_\nu \) which allows a nonzero mass for each of the three light neutrinos as well as a nonvanishing \(\theta _{13}\) . Leptonic Dirac CP violation mu...

摘要:The design and performance of piezoresistive MEMS-based MWCNT/epoxy composite strain sensor using COMSOL Multiphysics Toolbox has been investigated. The proposed sensor design comprises su-8 based U-shaped cantilever beam with MWCNT/epoxy composite film as an active sensing eleme...

摘要:In this article, effects of heat transfer on particle–fluid suspension induced by metachronal wave have been examined. The influence of magnetohydrodynamics (MHD) and thermal radiation are also taken into account with the help of Ohm’s law and Roseland’s approximation. ...
