    Colored noise influence on the system evolution

    Full text link
    We present a picture of phase transitions of the system with colored multiplicative noise. Considering the noise amplitude as the power-law dependence of the stochastic variable xax^a we show the way to phase transitions disorder-order and order-disorder. The governed equations for the order parameter and one-time correlator are obtained and investigated in details. The long-time asymptotes in the disordered and ordered domains on the phase portrait of the system are defined.Comment: 12 pages, 8 figures, LaTeX. Submitted to EPJ-

    Universality and self-similar behaviour of non-equilibrium systems with non-Fickian diffusion

    Full text link
    Analytical approaches describing non-Fickian diffusion in complex systems are presented. The corresponding methods are applied to the study of statistical properties of pyramidal islands formation with interacting adsorbate at epitaxial growth. Using the generalized kinetic approach we consider universality, scaling dynamics and fractal properties of pyramidal islands growth. In the framework of generalized kinetics, we propose a theoretical model to examine the numerically obtained data for averaged islands size, the number of islands and the corresponding universal distribution over the island size.Comment: 10 pages, 6 figure

    Purpose: The article identifies the differences between Ukraine and Poland in the image formation of the territory and investment attractiveness. Design/Methodology/Approach: A territorial-oriented approach is being introduced in Poland (an approach taking into account local conditions), which implies emphasis on a combination of investments and an integrated territorial approach, providing emphasis on activities that contribute to development. Findings: The regions of Ukraine are characterized by different levels of investment volume due to the differences in competitive advantages. In contradistinction from Ukraine, the competitive advantages of the territories provide a high level of investment attractiveness in Poland; they are integrated, and are generally based on advanced infrastructure (digital, business, transport), high-tech industries, advanced business services, economic zones, academic centers. Practical Implications: The conducted research makes it possible to identify several basic features of image formation and investment attractiveness of territories. Originality/Value: The basic key difference concerns the competence of countries’ integration of formed competitive advantages of the territory. The specified competence is traced in Poland, while in Ukraine the absence of this competence leads to underutilization of the regions’ potential.peer-reviewe

    The article examines the information society and its specifics. The Internet, which exerts a strong influence on the dynamics of social changes and the consciousness of modern youth, whose socialization in the information society is carried out under the powerful influence of mass media in general and the Internet in particular, is considered. It is noted that network communication has certain advantages that make us forget about its disadvantages, as, however, in the situation of information access, which makes both useful information, but also information of negative content, easily available. The information security of society was considered, and it was noted that information and technical progress contributes to the emergence of new types of dangers, the most significant of which include: information weapons, social crimes in the IT sphere, as well as the use of information technologies in political struggle. It should be noted that the security of personal information is closely related to the security of society. Information security of a person is a state of protection of his psyche and health from harmful information that can lead to inadequate perception ofreality and/or deterioration of his physical condition. Social information security is the ability of society and its individual members to freely exercise their constitutional rights related to the free acquisition, processing, creation and distribution of information, as well as the degree of protection against harmful informational influence. The drive towards an information society creates new types of dangers and threats. The society itself is forced to respond to the challenges of international, national, public and personal security. Methods of combating the information war and methods of protecting the information space of society are given. У статті досліджено інформаційне суспільство та його специфіку. Розглянуто Інтернет, який чинить сильний вплив на динаміку соціальних змін та свідомість сучасної молоді, соціалізація якої в інформаційному суспільстві здійснюється під потужним впливом ЗМІ в цілому та мережі Інтернет зокрема. Зазначено, що мережеве спілкування має певні переваги, які змушують забути про його недоліки, як і в ситуації інформаційного доступу, що робить легкодоступною як корисну інформацію, але також й інформацію негативного змісту. Розглянуто інформаційну безпеку суспільства і відмічено, що інформаційнотехнічний прогрес сприяє появі нових видів небезпек, до  найбільш значних із них належать: інформаційну зброю, соціальні злочини в  ITсфері, а також застосування інформаційних технологій у політичній боротьбі. Прагнення до інформаційного суспільства породжує нові види небезпек та загроз. Саме суспільство змушене реагувати на виклики міжнародної, національної, громадської та особистої безпеки.  Наведено способи боротьби з інформаційною війною та методи  захисту інформаційного простору суспільства.

    Stochastic effects at ripple formation processes in anisotropic systems with multiplicative noise

    Full text link
    We study pattern formation processes in anisotropic system governed by the Kuramoto-Sivashinsky equation with multiplicative noise as a generalization of the Bradley-Harper model for ripple formation induced by ion bombardment. For both linear and nonlinear systems we study noise induced effects at ripple formation and discuss scaling behavior of the surface growth and roughness characteristics. It was found that the secondary parameters of the ion beam (beam profile and variations of an incidence angle) can crucially change the topology of patterns and the corresponding dynamics
