Robust output stabilization: improving performance via supervisory control

We analyze robust stability, in an input-output sense, of switched stable systems. The primary goal (and contribution) of this paper is to design switching strategies to guarantee that input-output stable systems remain so under switching. We propose two types of {\em supervisors}: dwell-time and hysteresis based. While our results are stated as tools of analysis they serve a clear purpose in design: to improve performance. In that respect, we illustrate the utility of our findings by concisely addressing a problem of observer design for Lur'e-type systems; in particular, we design a hybrid observer that ensures ``fast'' convergence with ``low'' overshoots. As a second application of our main results we use hybrid control in the context of synchronization of chaotic oscillators with the goal of reducing control effort; an originality of the hybrid control in this context with respect to other contributions in the area is that it exploits the structure and chaotic behavior (boundedness of solutions) of Lorenz oscillators.Comment: Short version submitted to IEEE TA

State Youth Policy as Factor of Youth Welfare

This study demonstrates an attempt to build up the system of criteria for assessing the effectiveness of the youth policy implementation in education institutions and special organs. The assessing is underpinned by several criteria. These criteria are: criterion of matching priorities of youth policy expectations and the young people needs, criterion of consistency of priorities in forming and implementing national and regional youth policy, criterion of consistency work of various regional and local organizations and social institutions, criterion for mental and physical health of young people, criterion of the general level of development of social activity of youth, the level of youth`s crime

La competencia como herramienta para la asignación de recursos

El artículo explora la definición de «competencia» a través de un análisis de las interpretaciones existentes en la literatura científica. Los autores revisaron y revisaron creativamente más de 15 interpretaciones de autores existentes de este concepto. Los enfoques actuales para la clasificación de las competiciones se sistematizan y revisan creativamente. En el ejemplo de una tabla comparativa de enfoques de clasificación, se revelan las principales características de clasificación de las competiciones. Se considera la conveniencia de aplicar el concepto de «competencia» en concursos infantiles, escolares y estudiantiles, así como el concepto de «competencia abierta» utilizado en la adquisición de bienes, obras, servicios para satisfacer las necesidades estatales y municipales. Como resultado, los signos revelados de la competencia nos permiten concluir la conveniencia de utilizar este concepto como herramienta para la distribución de bienes materiales. En este caso, difieren solo en la escala de esta distribución. El artículo también explora la lista de olimpiadas y otros concursos intelectuales y (o) creativos, eventos dirigidos al desarrollo de habilidades intelectuales y creativas, habilidades para participar en la educación física y el deporte, interés en la ciencia (investigación), ingeniería, inventiva, creativa, física. actividades culturales y deportivas, así como la promoción del conocimiento científico, los logros creativos y deportivos, recomendados por el Ministerio de Educación de la Federación de Rusia. Como resultado, se ha identificado el público objetivo de los participantes para los que se inician los concursos

White organic light-emitting diodes with an ultra-thin premixed emitting layer

We described an approach to achieve fine color control of fluorescent White Organic Light-Emitting Diodes (OLED), based on an Ultra-thin Premixed emitting Layer (UPL). The UPL consists of a mixture of two dyes (red-emitting 4-di(4'-tert-butylbiphenyl-4-yl)amino-4'-dicyanovinylbenzene or fvin and green-emitting 4-di(4'-tert-butylbiphenyl-4-yl)aminobenzaldehyde or fcho) premixed in a single evaporation cell: since these two molecules have comparable structures and similar melting temperatures, a blend can be evaporated, giving rise to thin films of identical and reproducible composition compared to those of the pre-mixture. The principle of fine color tuning is demonstrated by evaporating a 1-nm-thick layer of this blend within the hole-transport layer (4,4'-bis[N-(1-naphtyl)-N-phenylamino]biphenyl (\alpha-NPB)) of a standard fluorescent OLED structure. Upon playing on the position of the UPL inside the hole-transport layer, as well as on the premix composition, two independent parameters are available to finely control the emitted color. Combined with blue emission from the heterojunction, white light with Commission Internationale de l'Eclairage 1931 color coordinates (0.34, 0.34) was obtained, with excellent color stability with the injected current. The spectrum reveals that the fcho material does not emit light due to efficient energy transfer to the red-emitting fvin compound but plays the role of a host matrix for fvin, allowing for a very precise adjustment of the red dopant amount in the device

Non-local convolution type operators with potential: essential and infinite discrete spectrum

The goal of this note is to study the spectrum of a self-adjoint convolution operator in $L^2(\mathbb R^d)$ with an integrable kernel that is perturbed by an essentially bounded real-valued potential tending to zero at infinity. We show that the essential spectrum of such operator is the union of the spectrum of the convolution operator and of the essential range of the potential. Then we provide several sufficient conditions for the existence of a countable sequence of discrete eigenvalues. For operators having non-connected essential spectrum we give sufficient conditions for the existence of discrete eigenvalues in the corresponding spectral gaps

NEUROMARKETING OF FINANCIAL REPORTING: RUSSIAN VIEW OF METHODOLOGY FOR IMPROVING REPORTING

Neuromarketing of financial reporting is a topic of interest to all representatives of the professional accounting and auditing environment. This paper will present the main problems of modern financial accounting, and possible solutions to them using neuromarketing methods. Thus, in order for financial statements to allow companies to attract new investments, as well as to avoid penalties from the tax authorities, organizations need to regard reporting as a commodity whose main consumers are users of these financial statements. In order to make this product interesting for consumers, companies need to attract their attention using neuromarketing methods, which will allow investors, tax authorities and lending organizations to quickly and efficiently use of data on the company\u27s business operations, as well as make the necessary economic decisions faster. Thus, an easy, understandable and accessible presentation of the results of an enterprise’s economic activity at the reporting date may allow both firms and users of financial statements to interact more effectively
