Algorithm for Calculating Primary Spectral Density Estimates Using FFT and Analysis of its Accuracy
Authors: Kolomys Olena , Luts Liliya
Published: October 2022

Introduction. Fast algorithms for solving problems of spectral and correlation analysis of random processes began to appear mainly after 1965, when the algorithm of fast Fourier transform (FFT) entered computational practice. With its appearance, a number of computational algorithms for the accelerated solution of some problems of digital signal processing were developed, speed-efficient algorithms for calculating such estimates of probabilistic characteristics of control objects as estimates of convolutions, correlation functions, spectral densities of stationary and some types of non-stationary random processes were built.
The purpose of the article is to study a speed-efficient algorithm for calculating the primary estimate of the spectral density of stationary ergodic random processes with zero mean. Most often, the direct Fourier transform method using the FFT algorithm, is used to calculate it. The article continues the research and substantiation of this method in the direction of obtaining better estimates of rounding errors.
Results. The research and substantiation of the method in the direction of obtaining more qualitative estimates of rounding errors, taking into account the errors of the input information specification, has been continued. The main characteristics of the given algorithm for calculating the primary estimate of the spectral density are accuracy and computational complexity.
The main attention is paid to obtaining error estimates accompanying the process of calculating the primary estimate of the spectral density. The estimates of the rounding error and ineradicable error of the given algorithm for calculating the primary estimate of the spectral density, which appear during the implementation of the algorithm for the classical rounding rule for calculation in floating-point mode with τ digits in the mantissa of the number, taking into account the input error, are obtained.
Conclusions. The obtained results make it possible to diagnose the quality of the solution to the problem of calculating the primary estimate of the spectral density of stationary ergodic random processes with a zero mean value by the described method and to choose the parameters of the algorithm that will ensure the required accuracy of the approximate solution of the problem. Keywords: primary estimation of spectral density, fast Fourier transform, discrete Fourier transform, rounding error, input error.
Parallel Implementation of Sparse Distributed Memory for Semantic Storage
Authors: Vdovychenko Ruslan , Tulchinsky Vadim
Published: October 2022

Introduction. Sparse Distributed Memory (SDM) and Binary Sparse Distributed Representations (Binary Sparse Distributed Representations, BSDR), as two phenomenological approaches to biological memory modelling, have many similarities. The idea of ??their integration into a hybrid semantic storage model with SDM as a low-level cleaning memory (brain cells) for BSDR, which is used as an encoder of high-level symbolic information, is natural. A hybrid semantic store should be able to store holistic data (for example, structures of interconnected and sequential key-value pairs) in a neural network. A similar design has been proposed several times since the 1990s. However, the previously proposed models are impractical due to insufficient scalability and/or low storage density. The gap between SDM and BSDR can be bridged by the results of a third theory related to sparse signals: Compressive Sensing or Sampling (CS). In this article, we focus on the highly efficient parallel implementation of the CS-SDM hybrid memory model for graphics processing units on the NVIDIA CUDA platform, analyze the computational complexity of CS-SDM operations for the case of parallel implementation, and offer optimization techniques for conducting experiments with big sequential batches of vectors.
The purpose of the paper is to propose an efficient software implementation of sparse-distributed memory for preserving semantics on modern graphics processing units.
Results. Parallel algorithms for CS-SDM operations are proposed, their computational complexity is estimated, and a parallel implementation of the CS-SDM hybrid semantic store is given. Optimization of vector reconstruction for experiments with sequential data batches is proposed.
Conclusions. The obtained results show that the design of CS-SDM is naturally parallel and that its algorithms are by design compatible with the architecture of systems with massive parallelism. The conducted experiments showed high performance of the developed implementation of the SDM memory block. Keywords: GPU, CUDA, neural network, Sparse Distributed Memory, associative memory, Compressive Sensing.

The Effect of National Entrepreneurship on National Competitiveness: Linear and Non-linear Regression Analysis
Authors: KAYGISIZ Esra G. , KARA Karahan
Published: October 2022

National entrepreneurship and national competitiveness are two basic factors that affect the economic development of countries. In this study, the effect of national entrepreneurship on national competitiveness is examined. Linear and non-linear regression analyzes were applied as research method. Non-linear regression model estimates were obtained with the curve estimation model application. Obtained models are presented comparatively. The sample consists of 52 countries. The national entrepreneurship scores of the countries were obtained from the “Global Entrepreneurship Monitor (GEM)” reports. National competitiveness scores are derived from “Global Competitiveness Index (GCI)” reports. The research period is 2019 before the pandemic. According to the research findings, the model with the highest percentage of explanation among the non-linear models is determined as the "Qubic" estimation model. When the Qubic non-linear model and linear model are compared, both models are found to be significant. In addition, it is concluded that the percentage of explanation of the non-linear model is higher than the linear model. Based on the findings, it has been suggested to develop country-specific entrepreneurship strategies as well as general entrepreneurship strategies in determining national entrepreneurship strategies.

Classroom Experiments Testing Constancy of Speed of Photons
Authors: peng hui
Published: October 2022

Special Relativity (SR) is the cornerstone for modern physics and variety of applications. SR is based on two postulates, the principle of relativity (the first postulate) and the principle of constancy of speed of light (the second postulate). Recently we have (1) shown that the light propagate as particles/photons in the “pure” wave experiments, such as double slit and grating experiments; (2) proposed experiments to measure the speed of the photons by an observer moving relative to the source and thus, to test the second postulate for photons. In this article we propose a classroom experiment to test the second postulate. If the experiments show the existence of interference pattern (the negative result), the constancy of the speed of the photons holds, namely the second postulate of SR is experimentally confirmed. If the experiments show no interference pattern (positive result), then the propagation speed of photons is not constant, namely, the second postulate of SR is disproved. Either negative result or positive results would be profoundly significant.

A Necessária Flexibilidade do Protesto Especial para o Atendimento ao Saneamento do Sistema Econômico: Uma análise doutrinária e jurisprudencial
Authors: Xavier Camila Costa
Published: October 2022

O presente artigo tem como objetivo analisar a viabilidade da flexibilização do protesto especial para fins falimentares, verificando o atual posicionamento do Superior Tribunal de Justiça. Será utilizada, para tanto, pesquisa doutrinária e jurisprudencial, a fim de uma consolidação do raciocínio. A limitação da produção de provas no processo de falência, com previsão legal da necessidade de um protesto especial, com finalidade específica, busca uma segurança do regime falimentar, que é a última tentativa de sobrevivência de uma empresa em crise. Entretanto, o enrijecimento legal acaba por desvirtuar a busca do saneamento do sistema econômico. Percebe-se, assim, a acertada posição dos tribunais, com a flexibilização do instituto do protesto especiais para fins falimentares, sem que isso se esbarre nos critérios legais.

PROFITABILITY OF INCENTIVE PURCHASE PRICES FOR WIND FARM PROJECTS IN CROATIA
Authors: Diana Ognjan  , Zoran Stanić  , Željko Tomšić
Published: October 2022

In 2007 the Croatian energy legislation underwent a series of changes. Along with the opening of the electricity market to all legal entities, on 1 July 2007 a package of five bylaws on the incentives to electricity generation from renewable energy resources entered into force. The incentive method Croatia has opted for are feed-in tariffs, the widest-spread and currently most successful method in the European Union. In Croatia a massive venture capital interest in renewables is recently manifest, especially wind power projects. This raises a question about the real profitability of such projects and whether or not the incentive puchase price is high enough to make the wind power projects viable. The present work analyses a generic wind power plant project, installed power 25 MW (the reasons why this rating has been chosen are given later on), by using RETScreen International Software, developed in Canada and used throughout the world. The introductory part, which describes the current situation in Croatia regarding renewables, is followed by a brief overview of newly introduced bylaws aimed to provide incentives for electricity generation from renewables. The works explains in detail the input of all relevant technical, economic and financial parameters and shows the results of modelling a wind power plant with capacity factors of 18 %, 20 %, 22 %, 25 %, 27 % and 30 % by using RETScreen International Software. A detailed susceptibility and risk analysis is given for a wind power plant with the capacity factor of 25%, followed by a conclusion.

Distortions of the sinusoidal form occurring in three-phase networks essentially change the characteristics of the network. It is shown how the phase and line values in networks with distorted sinusoids are computed. At the end, an example is given of how higher harmonics in a certain power supply network are computed by using software simulation, and another example from practice where the results of measuring higher harmonics in a 10 kV power distribution network are shown.

In the global economy today energy certainly has a strategic importance, whereas in terms of energy supply and securing of primary energy sources a special role is played by crude oil and, to an increasing extent since the start of the new century, natural gas. In the past two decades the consumption of natural gas has been significantly rising and natural gas as energy source is gaining, like crude oil, a strategic importance. While oil is still a dominant energy source in the overall global consumption, which is not going to change in some decades to come, it is anticipated that the share of natural gas in the world energy consumption will go up by 2050 from the present 23 % to nearly 45 %. Securing oil and gas supply is hence a primary task of the energy policy of any country. Considering the fact that 70 % of its primary energy needs Croatia meets by using liquid and gaseous fuels, it is extremely important to review the needs, circumstances and situations concerning natural gas supply and to analyze the overall security of natural gas supply as a prerequisite for Croatia’s energy security as a whole.

The world is confronting the twin crises of fossil fuel depletion and environmental degradation. Alternative fuels, energy conservation and management, energy efficiency and environmental protection have become increasingly import in recent years. Among alternative fuels, esterified vegetable oils hold good promise as eco-friendly alternatives to diesel fuel. In rural India, 90 % of the petroleum diesel requirement is for agricultural equipment such as tractors and threshers. Marginal farmers and large landholders can meet their diesel requirement by sowing oil yielding crops on their own lands. This paper evaluates the feasibility of the local production of vegetable oil for a small representative village in central India. Fatty acid methyl esters of cottonseed oil, soybean oil, balanites oil and jatropha oil were analyzed for their properties and performance in diesel engines. The land required to grow these oil crops in order to meet rural agricultural diesel requirements was estimated. The results indicate that the calorific value of these methyl esters is 93 % that of diesel and the other properties are quite comparable with diesel. Engine performance analysis of these methyl esters indicates that there is a slight decrease in thermal efficiency of approximately 3,23 %, while emissions are reduced by 8 % to 10 % as compared to diesel. Economic analysis was also performed and it was found that vegetable oil derivatives as diesel fuel substitutes are costlier than mineral diesel.
Increasing the reliability and availability of the electric motor using combined static and dynamic diagnostics

The aim of this paper is to point out the importance of early diagnostics and assessment of the condition of the electric motor in increasing the reliability and availability of the plant. Electric motors are unavoidable elements in every production process. As the complexity of the process increases, the number of electric motors involved in it increases. By increasing the number of electric motors, the possibility of cancelling and interrupting production increases. It is therefore very important to monitor the situation and detect defects at an early stage so that timely repair or replacement can be planned, without affecting the production process. Modern diagnostic methods that can be used both during the operation of the electric motor, and with the dismounted and dismantled electric motor are presented in the paper. With good organization and testing schedule and a combination of static and dynamic diagnostic methods, the reliability and availability of the plant can be significantly increased. With increased reliability and availability, a reduction in maintenance costs is achieved. In this article, some examples from the author's practice are given, when serious engine defects were discovered.  These cases confirm the value of predictive testing to increase reliability of  electric motor.

We started a survey with CHARA/MIRC-X and VLTI/GRAVITY to search for low-mass companions orbiting individual components of intermediate-mass binary systems. With the incredible precision of these instruments, we can detect astrometric “wobbles” from companions down to a few tens of microarcseconds. This allows us to detect any previously unseen triple systems in our list of binaries. We present the orbits of 12 companions around early F- to B-type binaries, 9 of which are new detections and 3 of which are first astrometric detections of known radial velocity (RV) companions. The masses of these newly detected components range from 0.45 to 1.3 M
⊙. Our orbits constrain these systems to a high astrometric precision, with median residuals to the orbital fit of 20–50 μas in most cases. For seven of these systems we include newly obtained RV data, which help us to identify the system configuration and to solve for masses of individual components in some cases. Although additional RV measurements are needed to break degeneracy in the mutual inclination, we find that the majority of these inner triples are not well aligned with the wide binary orbit. This hints that higher-mass triples are more misaligned compared to solar and lower-mass triples, though a thorough study of survey biases is needed. We show that the ARMADA survey is extremely successful at uncovering previously unseen companions in binaries. This method will be used in upcoming papers to constrain companion demographics in intermediate-mass binary systems down to the planetary-mass regime.
Differential Behaviors of Suprathermal 4He and Fe Populations in the Interplanetary Medium during Solar Cycle 24

Published: October 2022

Investigations on the solar cycle variation of the properties of suprathermal populations (H and other heavy ions like 4He, 3He, C, O, and Fe) in the solar wind are sparse and hence poorly understood. In the present investigation, solar cycle variations of “quiet” time suprathermal elements are investigated using <∼ 1 MeV n−1 particle flux data obtained from the Ultra-Low Energy Isotope Spectrometer on board the Advanced Composition Explorer satellite during solar cycles 23 and 24. The analysis reveals that helium (4He) shows zero or positive lags with respect to sunspot numbers in solar cycle 23 while it shows zero or negative lag in solar cycle 24. On the contrary, although iron (Fe) shows a zero or positive lag in cycle 23 similar to 4He, it shows only a zero lag in cycle 24 and no negative lag is seen. Further, significant differences in the spectral indices are seen between 4He and Fe in cycle 24 compared to cycle 23. These results suggest that generation mechanisms responsible for suprathermal 4He and Fe underwent changes in cycle 24 and these mechanisms are probably dependent on the first ionization potential and mass-to-charge ratio. This proposition gets credence from the fact that changes in the lags and spectral slopes for C and O are not significantly different in cycles 23 and 24.
An Argument in Favor of Magnetic Polarity Reversals Due to Heat Flux Variations in Fully Convective Stars and Planets
Authors: Nigro Giuseppina
Published: October 2022

Low-mass M dwarf stars, T Tauri stars, as well as planets such as the Earth and Jupiter are permeated by large-scale magnetic fields generated by the convection-driven dynamo operating in their convection zones. These magnetic fields are often characterized by a significant time variability, most prominently expressed by the inversions of their polarity, denoted as reversals, whose mechanism has not been completely understood. This work aims to gain some insights into the mechanism that generates these reversals. With this purpose, a simplified nonlinear model is developed to investigate the role played in polarity reversals by the convective heat transfer occurring in stellar and planetary convection zones. A model result is the enhancement of the global heat transport before polarity reversals, showing the crucial role that heat transport might play in their occurrence. This role is elucidated by considering that a reversal has a greater than 70% probability of occurring during a burst of convective heat transport. This high probability has been found in 94 out of 101 numerical simulations obtained by changing characteristic model parameters. Moreover, the causal relationship between the convective heat flux growth and the magnetic field variations is highlighted by the temporal antecedence of the former relative to the latter and by convergent cross mapping, namely a statistical test for detecting causality. It would thus be expected that higher levels of temporal variability in the planetary and stellar magnetic fields may be correlated to a higher heat transfer efficiency achieved in the interior of these celestial bodies.
Predicting the Stability of Hierarchical Triple Systems with Convolutional Neural Networks
Authors: Lalande Florian , Trani Alessandro Alberto
Published: October 2022

The dynamical stability of hierarchical triple systems is a long-standing question in celestial mechanics and dynamical astronomy. Assessing the long-term stability of triples is challenging because it requires computationally expensive simulations. Here we propose a convolutional neural network model to predict the stability of equal-mass hierarchical triples by looking at their evolution during the first 5 × 105 inner binary orbits. We employ the regularized few-body code tsunami to simulate 5 × 106 hierarchical triples, from which we generate a large training and test data set. We develop 12 different network configurations that use different combinations of the triples’ orbital elements and compare their performances. Our best model uses six time series, namely, the semimajor axes ratio, the inner and outer eccentricities, the mutual inclination, and the arguments of pericenter. This model achieves excellent performance, with an area under the ROC curve score of over 95% and informs of the relevant parameters to study triple systems stability. All trained models are made publicly available, which allows predicting the stability of hierarchical triple systems 200 times faster than pure N-body methods.
