A modification of model describing optical structures forming in nonlinear ring interferometer (NRJ) containing liquid crystal having Kerr effect is suggested. Case of optical field which is turned through some angle in cross section plane of the laser beam (in feedback of the NRJ) is investigated. It is found that both screw dislocation order of the wavefront entering on the NRJ input and phase shift of the optical field in circuit of feedback ofthe NRT effects on optical forming process equally strongly. A theoretical analysis and simulations show any new possibilities ofNRJ applications: the identification of spiral dislocation order of an optical vortex (by shape of optical structures self-organizating in cross section plane of laser beam in NRI); the compensation of the optical vortex effect on evolution and result of the optical forming in NRI; basis of an arithmetic-logical optical device realizing addition operation.
The aim of the work is an application of the theory of Goal-oriented System of Activity to analysis and organization of effective contract targeted training at higher education institutions. The organization of targeted training of specialists is considered as one of the components of public administration to address staff problems in various regions and sectors of the economy in the context of rapidly changing demands of society, to implement promising youth policy and mitigate demographic problems. An algorithmic chain of meaningful actions is con structed on the basis of the methodology of the Goal-oriented System of Activity, which takes into account the real state of human, intellectual, material and economic resources and enables to minimize existing contradictions and, accordingly, ensure the establishment of partnerships between all interested participants in the process of targeted training (government agencies, employers, higher education institutions and students). As an example, four stages of contract teacher training have been considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
