The article presents the construction of a regression model based on information about the number of computer game players in the world and finding factors that affect the growth of this indicator. To avoid inadequacy of the model, outliers and factors that are strongly related to each other were excluded after formatting the data - thus, multicollinearity was excluded in this regression analysis. The main goal of the article is to build a linear regression model that will reflect all the coefficients needed to write the function for predicting the number of players in the world, assess the adequacy of the constructed model, and evaluate the residuals of comparing the predicted number of players with real data. If an adequate model is achieved (measuring the F-test, P-significance and R-square), in which the residuals of the predicted number and the real number will be close to zero, it is acceptable to assume that it can be used to predict the number of players in the world for the next year. © 2023 IEEE.

This study presents the findings of a new financial risk system with one absolute function and two quadratic nonlinearities. The rich dynamic behaviors of the new financial risk system are discussed analytically and numerically through stability analysis, phase portrait, bifurcation diagram, Lyapunov exponent, multistability and coexisting attractors. In addition, a new financial risk system with two quadratic nonlinearities and one absolute function shows multistability and coexistence of chaotic attractors. Using adaptive feedback control, we established a new control law for fully synchronising the proposed chaotic financial systems with itself. To conclude, some numerical simulation was presented using MATLAB to illustrate the efficiency of the designed method. © 2023, The Author(s), under exclusive licence to Springer Nature India Private Limited.

A simulation model of a simple supply chain consisting of a single distribution center and several points of sale was created. Initially, a new model was created with the name "Suplly Chain"and watches as units of model time. Next, a GIS (geographic information system) map was added to the diagram of the main object using the standard display settings. The distributor properties were defined and it marked the distribution point on the map. Next, retailers were added to the map: using the OpenStreetMap online server, to which AnyLogic sends addresses and receives coordinates and automatically arranges retailers. Manually added the properties of retailers. The next step was to create a model of trucks and their movement logic is set. To do this, a state diagram was used, with the help of which a diagram of the state of the logic of trucks was obtained. Using the New Agent Wizard, add a new agent type - order. It also changed the status chart to display order information. The created model was supplemented, where time was added for unloading and loading trucks from retailers. A basic simulation model of supply chains was built, and ideas for improving this model were considered. © 2023 IEEE.

The definition of a turbulent flow is still not mathematically defined. Different methods exists that provide different definitions resulting in different approaches and classifications of the laminar-turbulent transition as well as the fully developed turbulent flows. The paper includes the analysis of different stages of turbulence development, specific methods that are used in each stage and possible methods of unification of these methods based on the nonlinear-dynamical approach. Results are demonstrated for some characteristic fluid dynamics problems. Future highlights on the path to possible unification are discussed. © 2020 Institute of Physics Publishing.

Research for nonlinear optical properties of highly conjugated organometallic compounds and self-assembled photonic architectures is growing very rapidly and play a major role in emerging photonic technologies. Innovative compounds for communications, optical switching, optical data information storage and optical limiting require an important development of materials based on molecular engineering of advanced molecular systems with exceptional nonlinear optical (NLO) responses. Thus, organic materials, polymeric materials, organometallic or coordination metallic complexes have been the subject of both experimental and theoretical investigations during last recent years because of their valuable potential applications in photonics and optical devices. The aim of the present work is to study the impact of the chemical structure on the photoluminescence response of Znq 2 , Cuq 2 and Alq 3 studied organometallic compounds. These ones were deposited as thin layers by using the Physical Vapor Deposition (PVD) apparatus. The photoluminescence gives information about the photophysical properties of studied thin layers. The time-resolved photoluminescence was used to measure the decay time in the real time precisely. The chemical structure has an important impact on the photoluminescence. However, the important photoluminescence results in visible range allow the studied complexes to be used as a good material for the production of Organic Light Emitting Diode (OLED). The effect of magnetic field and its role in controlling nonlinear optical properties will be also discussed.

the DC/AC interaction and the presence of the high nonlinearity in the HVDC links, these problems needs to examine the behavior of the system in steady-state and transient conditions in order to define the great role of protection functions and control parameters. Furthermore, control and protection systems are a vital part of an HVDC system to guarantee the safety, reliability, and stability of its operation. This research aim is to provide the solutions for control and protection problems that can occur in HVDC link. In this paper, we study how we mitigate this serious malfunction of commutation failure process in the operation of HVDC converters. Indeed some protection functions like the commutation failure prevention. Furthermore, HVDC transmission systems are vulnerable to DC faults and its protection becomes ever more important with the fast growth in the number of installations. Finally, the dynamics of the studied power system including the HVDC link is thoroughly investigated through various simulation scenarios.

The restoration of subsidence waterlogging areas has the potential to facilitate carbon accumulation in the coal mining areas with high ground water table. Nevertheless, the impact of restoration and management strategy on the soil organic carbon (SOC) and the labile organic carbon(LOC) have not been sufficiently demonstrated. In this study, SOC and LOC fractions, including light fraction organic carbon(LFOC), particulate organic carbon(POC), and dissolved organic carbon(DOC) within the 0-50cm profiles, were determined in the reference cropland(RC) and three types of subsidence waterlogging areas including aquaculture waterlogging area(AWA), deep waterlogging area(DWA) and shallow waterlogging area(SWA) in Xinglongzhuang Coal Mine, Shandong Province, China. Our results showed that compared with the reference cropland SOC and LOC decreased by 4.13%, 25.03%, and 77.91% in SWA, DWA, and AWA, respectively. The vital depletion was in the 0-10cm soil layer, which indicates that the recovery of total functional pools of SOC after subsidence and the succession of ecological systems takes a longer time. The liability of POC was highest among the three types of labile organic fractions which could indicate the mining subsidence triggered the soil redistribution and impact the carbon accumulation. With comparatively less interference on the soil profile, the liability of LFOC and POC decreased with soil depth, while DOC increased in DWA and SWA. And there was a large discrepancy in AWA, with the liability of LOC fractions fluctuating because of intensive engineering soil disturbance. Labile organic C fractions were closely associated and correlated with soil properties, especially TN and TP. Overall, the restoration and management have a vital impact on the soil organic carbon pool, it is suggested that shallow water, natural geomorphology-based topography, less soil disturbance, well development of vegetation communities, and continuous monitoring of soil and water properties

This paper presents an analysis of a data set to determine the factors influencing airline passenger satisfaction. The study examines various criteria such as gender, customer type, age, travel type, class, and range to assess their impact on passenger satisfaction. The dataset consists of 25 columns, including attributes like Wi-Fi availability, convenience of online booking, seat comfort, in-flight entertainment, baggage handling, and overall satisfaction. The sample is relatively balanced, with equal representation of men and women, predominantly repeat customers, and a majority flying for business purposes. Key findings include a strong correlation between departure and arrival delays, higher satisfaction among passengers in business class, and positive ratings for Wi-Fi service correlating with overall satisfaction. Correlation analysis reveals interdependencies between different attributes, such as the influence of cleanliness on seat comfort and food and beverage ratings. In addition, a neural network forecasting model is used to estimate the average ratings of passengers, although with low accuracy, which was later excluded. Finally, a decision tree algorithm is utilized to identify the most significant attributes affecting passenger satisfaction words. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
