AGENT-BASED MODELING IN MULTI-LEVEL INDUSTRIAL ECOSYSTEMS DEVELOPMENT

In industrial ecosystems development, there are currently trends towards deepening vertical and horizontal integration within the innovation processes framework. They entail approaches complication to management functions implementation. Management and development problems solutions in multi-level industrial ecosystems becomes particularly relevant. The study’s purpose is to formulate possible approach to such problems solving that can increase management decision-making efficiency. The work proposes simultaneous agent-based modeling and multi-level digital twins use in order to simulate economic processes. The study proposes multi-level industrial systems conceptual scheme for an agent-based modeling, taking into account its’ vertically hierarchical structure. The proposed model identifies four levels (with their own agents), differing in the nature of the tasks being solved, the responsibility area, organizational and economic mechanisms used. It is proposed to base the model on economic and mathematical tools, in particular computer modeling methods, creating digital twins specifically. Digital twins are used to analyze production chains, assess internal and external factors effect, develop alternatives and select most preferable solutions to emerge management problems. At the same time, it was determined that digital twins structure should be multi-layered, where each subsequent level incorporates digital twins developed on the previous one, endowed with implemented functions certain set. It is substantiated that one of the important tasks is to determine industrial ecosystem digital twin managerial layer optimal configuration. This layer is responsible for modeling the organizational and managerial component and is built on needs to achieve financial and economic activity target indicators. The study proposes and describes the agent-based model operation mechanism, the development of which is allows to produce management strategies based economic and mathematical modeling complex tools, scenario and forecast analysis and digital twins numerical modeling

Assessing the importance and expression of the 6-year geomagnetic oscillation

The first time derivative of residual length-of-day observations is known to contain a distinctive 6 year periodic oscillation. Here we theorize that through the flow accelerations at the top of the core the same periodicity should arise in the geomagnetic secular acceleration. We use the secular acceleration of the CHAOS-3 and CM4 geomagnetic field models to recover frequency spectra through both a traditional Fourier analysis and an empirical mode decomposition. We identify the 6 year periodic signal in the geomagnetic secular acceleration and characterize its spatial behavior. This signal seems to be closely related to recent geomagnetic jerks. We also identify a 2.5 year periodic signal in CHAOS-3 with unknown origin. This signal is strictly axially dipolar and is absent from other magnetic or geodetic time series

Russian Egyptology (1914-1945)

The period from 1914 to 1945 in the history of Russia is marked with a number of major shocks: World War I, the revolution of 1917 and the following civil war, the establishment of a totalitarian ideological rule accompanied with terror, and the participation of the USSR in World War II (the Great Patriotic War). They all deeply affected the Russian (Soviet) scholarship including Egyptology. The tradition of the earlier, imperial period continued until the early 1920s in the research of Vladimir Golenischeff outside Russia and, briefly, in the work of Boris Turaev and his students. It so happened that this generation of Russian Egyptologists became actually extinct, and the Egyptological school had to be shaped anew in the time of post-revolutionary reconstruction. This process was influenced in the 1920s with what might be defined as “modernist” trends; but a new standing tradition emerged only in the 1930s, largely due to the efforts of Vassiliy Struve. This scholar of a pre-revolutionary breed luckily combined his good training with a grasp of topical ideology, i.e. the Soviet Marxist historical scheme. This meant a greater shift in research towards socio-economic issues, though other themes were not ignored. At the same time, the 1930s saw the beginning of research by Yuri Perepyolkin, whose specific method was developed further in the works of the Leningrad/St. Petersburg Egyptological school in the second half of the 20th century

Late Dynastic Period

The Late Dynastic Period is the last period of Egyptian independence under Dynasties 28 to 30 (404 - 343 BCE). As for Egypt’s position in the world, this was the time their military and diplomatic efforts focused on preventing reconquest by the Persian Empire. At home, Dynasties 28 - 29 were marked by a frequent shift of rulers, whose reigns often started and ended violently; in comparison, Dynasty 30 was a strong house, the rule of which was interrupted only from the outside. Culturally this period saw the continuation of certain Late Egyptian trends (archaistic tendency, popularity of animal cults, cult of Osiris and divine couples), which became the platform for the evolution of the Ptolemaic and Roman Periods. &nbsp
