Abstract The aim of this paper is to analyse a planar optical waveguide with Kerr-type nonlinear cladding and thin linear overlayer separating the guiding core. results numerical calculations show that bistable behaviour waveguides can be easily controlled by changing parameters additional layer. analysis based on self-consistent iteration procedure which provides relevant dispersion characteri...

objectives: civil rights may cover different aspects of citizens’ lives. all the members of the society should have equal access to the public facilities and public transportation system. barriers and obstacles in society may limit the accessibility of these facilities to the disabled people. methods: this article contains a part of the results in a phenomenological study of the disability righ...

Within general relativity, we construct sequences of rapidly rotating Dirac stars consisting a spinor fluid described by an effective equation state. We find the physically relevant domain stable configurations and calculate their principal characteristics which are completely determined central density fluid, mass nonlinear field, velocity rotation. It is demonstrated that for certain choice f...

Real-time hybrid simulation (RTHS) is a testing method by which structural system divided into analytical and experimental substructures. This paper proposes methodology to conduct RTHS for structures that use passive nonlinear viscous dampers (NLVDs), some of are physically tested in the substructure others via online model updating (OMU). The proposed uses response modelled NLVD improve predi...
