    On the number of zeros of Melnikov functions

    Full text link
    We provide an effective uniform upper bond for the number of zeros of the first non-vanishing Melnikov function of a polynomial perturbations of a planar polynomial Hamiltonian vector field. The bound depends on degrees of the field and of the perturbation, and on the order kk of the Melnikov function. The generic case k=1k=1 was considered by Binyamini, Novikov and Yakovenko (\cite{BNY-Inf16}). The bound follows from an effective construction of the Gauss-Manin connection for iterated integrals

    The procedure of organizing, holding tenders and reviewing projects is a formal process, based on expert evaluation, which does not consider the peculiarities of high-tech projects, especially in terms of obtaining possible intermediate results. It has a high degree of uncertainty about the final product from the standpoint of its consumer and functional parameters, which causes a high degree of probability of making suboptimal decisions.The solution of the above problem proposed in this article is to form a specialized organizational and executive structure of the project implementation within the framework of the system integration of the participants or executors of the project.This article proposes a more politically correct system legitimacy in the framework of existing legislation, because the previous one had a lack of selection procedure of the implementation of high technology projects.El procedimiento de organización, realización de ofertas y revisión de proyectos es un proceso formal, basado en la evaluación de expertos, que no considera las peculiaridades de los proyectos de alta tecnología, especialmente en términos de obtener posibles resultados intermedios. Tiene un alto grado de incertidumbre sobre el producto final desde el punto de vista de sus parámetros funcionales y de consumo, lo que causa un alto grado de probabilidad de tomar decisiones subóptimas.La solución al problema anterior propuesto en este artículo es formar una estructura organizativa y ejecutiva especializada de la implementación del proyecto en el marco de un sistema de integración de los participantes o ejecutores del proyecto.Este artículo propone un sistema de legitimidad más políticamente correcto en el marco de la legislación existente, ya que el anterior carecía de un procedimiento de selección de implementación de proyectos de alta tecnología.O procedimento de organizar, fazer ofertas e revisar projetos é um processo formal, baseado na avaliação de especialistas, que não considera as peculiaridades de projetos de alta tecnologia, especialmente em termos de obtenção de possíveis resultados intermediários. Tem um alto grau de incerteza sobre o produto final do ponto de vista de seus parâmetros funcionais e de consumo, o que causa um alto grau de probabilidade de tomar decisões sub-ótimas.A solução para o problema anterior proposto neste artigo é formar uma estrutura organizacional e executiva especializada para a implementação do projeto no âmbito de um sistema de integração dos participantes ou executores do projeto.Este artigo propõe um sistema de legitimidade mais politicamente correto no âmbito da legislação existente, uma vez que o anterior não dispunha de um procedimento de seleção para a implementação de projetos de alta tecnologia.Процедура организации, проведения конкурсов, рассмотрения проектов носит зачастую формальный характер, основанный в значительной степени на экспертной оценке, не учитывающий особенности высокотехнологических проектов, прежде всего в части получения возможных промежуточных результатов, высокую степень неопределенности по конечному продукту с позиций его потребительских и функциональных параметров, что обусловливает высокую степень вероятности принятия неоптимальных решений.Предлагаемое в данной статье решение вышеуказанной проблемы заключается в формировании специализированной организационно – исполнительской полиструктуры реализации проекта в рамках системной интеграции участников – исполнителей работ по проекту.Разработан инструментарий, представленный процедурой и экономико-математическим аппаратом объективизации процессов реализации наукоемких проектов с позиций их стратегической ориентированности и одновременно потребительской результативности.В отличие от существующей недостаточно представительной однокритериальной процедуры отбора и контроля за реализацией наукоемких проектов, предложена более корректная поликритериальная система, лигитимная в рамках существующего законодательства

    Often the question arises, how to assess the quality of the goods. To determine either fake or genuine product, there are many different methods and techniques, but there is no universal method for determining the low-quality products. It is proposed to provide a compact device for use with any mobile device, such as a cell phone, as well as the creation of algorithm and software that will allow the end user to easily use the device for self-determination of the authenticity and quality of the goods, comparing the results of the spectra analysis

    Arcless opening of direct current circuits in technical systems

    Operation of the proposed DC circuit breaker consists in the fact that the closing of the thyristor in the DC power circuit with an inductive load results from opening the auxiliary circuit with a current value several fold less than the load current. The power and auxiliary circuits are connected by means of a current transformer having counter switch windings. After switching, the load is shunted by a diode and does not affect the transition process. Simulations and experimental tests of the DC circuit breaker model showed its performance capability, and the breaker can be used for switching in existing DC high current circuits with inductive loads

    Optimizing the economic information transparency level of high-tech enterprises in the post-industrial globalized economy

    Purpose: Managerial conditions of economic operation of a high technology enterprise as it integrates into the global economy that is essentially postindustrial and globalized were considered in this article. Design/Methodology/Approach: An inevitable immersion of the enterprise into the well-developed external infosphere, as well as a membrane borderline between the external and the internal infospheres were shown. The enterprise was represented dually – as both a donor and a recipient of information resources. Findings: An interpretation of the content of the infosphere was presented. Multiple causes of the discrete nature of the enterprise’s infosphere implementation were shown. The concept of “informational economic transparency” of an enterprise was introduced, and multiple components determining transparency levels were described. Practical Implications: The influence of transformations of informational economic transparency of an enterprise on external impacts on it from legal relations parties. Positive and negative effect of increases and decreases in the informational economic transparency of the enterprise were highlighted in the context of its influence on the economic counterpart and conflict-studies situations. The understanding of the specialized control object was provided. The optimizability of a level of the transparency in the aspect of target orientation of the enterprise was demonstrated. Originality/Value: A structural prototype to the primary support managerial toolkit in the shape of a DSS, a recommender system, allowing to conduct required feasibility studies of managerial decisions was proposed.peer-reviewe
