A method for estimating the statistical error of the solution in the inverse spectroscopy problem

A method for obtaining the interval of statistical error of the solution of the inverse spectroscopy problem, for the estimation of the statistical error of experimental data of which the normal distribution law can be applied, has been proposed. With the help of mathematical modeling of the statistical error of partial spectral components obtained from the numerically stable solution of the inverse problem, it has become possible to specify the error of the corresponding solution. The problem of getting the inverse solution error interval is actual because the existing methods of solution error evaluation are based on the analysis of smooth functional dependences under rigid restrictions on the region of acceptable solutions (compactness, monotonicity, etc.). Their use in computer processing of real experimental data is extremely difficult and therefore, as a rule, is not applied. Based on the extraction of partial spectral components and the estimation of their error, a method for obtaining an interval of statistical error for the solution of inverse spectroscopy problems has been proposed in this work. The necessity and importance of finding the solution error interval to provide reliable results is demonstrated using examples of processing Mössbauer spectra.

Mathematical Modelling and Study of Stochastic Parameters of Computer Data Processing

The main goal of dispatching strategies is to minimize the total time for processing tasks at maximum performance of the computer system, which requires strict regulation of the workload of the processing units. To achieve this, it is necessary to conduct a preliminary study of the applied model for planning. The purpose of this article is to present an approach for automating the investigation and optimization of processes in a computer environment for task planning and processing. A stochastic input flow of incoming tasks for processing is considered and mathematical formalization of some probabilistic characteristics related to the complexity of its servicing has been made. On this basis, a software module by using program language APL2 has been developed to conduct experiments for analytical study and obtaining estimates of stochastic parameters of computer processing and dispatching. The proposed model is part of a generalized environment for program investigation of the computer processing organization and expands its field of application with additional research possibilities.

HOW TO COLLECT THE PICTURES ON THE FISH MORPHOLOGY.

Collecting fish morphology data in the field is usually difficult and time consuming. The method of digital photography with further computer processing is currently widely used in biology and facilitates the acquisition of morphological data of fish. The article gives recommendations for obtaining high-quality digital photographs of fish, which we have tested empirically on a large ichthyological material. The studies of the morphological variability of fish following these recommendations showed several positive aspects: accelerating the collection of morphological material, increase of the accuracy of the data obtained, organizing the material in the form of a data bank, the ability to repeatedly refer to a photograph of an object, and a quick exchange of material.

The Advent of Artificial Intelligence in Diabetic Foot Medicine: A New Horizon, a New Order, or a False Dawn?

In a world where automation is becoming increasingly common, easier collection of mass of data and powerful computer processing has meant a transformation in the field of artificial intelligence (AI). The diabetic foot is a multifactorial problem; its issues render it suitable for analysis, interrogation, and development of AI. The latter has the potential to deliver many solutions to issues of delayed diagnosis, compliance, and defining preventative treatments. We describe the use of AI and the development of artificial neural networks that may supplement the failed networks in the diabetic foot. The potential of this technology, current developing applications, and their limitations for diabetic foot care are suggested.

Fixed Lexical Combinations in the Book Poetic «Personal Series» in the Light of Computer Research and Author’s Reflection

he article is devoted to the identification of repeated lexical combinations in poetic texts using the original software system «Hypertext Search for Companion-words in Author’s Texts». The steadily adjacent words found in this way turn out to be characteristic either for the majority of native speakers, or for a certain poetic tradition, or for a particular author. The study objective is to compare the results of the most objective computer processing of texts with the philologists’ interpretation and subjective author’s commentary, as well as to outline insufficiently studied issues of the poetry psychology.

Analysis of electrogastroenterographic signals using the computer method

Electrogastroenterography is a field that studies the condition of the gastrointestinal tract. Electrophysiological signals contain artifacts that are not directly related to the activity of the organism, and the filtration of such artifacts is an important issue. Electrogastroenterography is a field that studies the condition of the gastrointestinal tract. This method is associated with radiography, ultrasound, endoscopy. In these methods, electrical signals are taken from the surface of the abdominal cavity. For this purpose, the issues of elimination of artifactors, processing and analysis of signals on the example of electrogastroenterograms for processing and measurement of electrophysiological signals were considered. Keywords:Electrogastroenterography, non-stationary signals, electrophysiological signals, computer processing, wavelet conversion, frequency modulation, wavelet Morle function

Finding the dominant zero of the energy probability distribution

In this work, we present a computational procedure to locate the dominant Fisher zero of the partition function of a thermodynamic system. The procedure greatly reduces the required computer processing time to find the dominant zero when compared to other dominant zero search procedures. As a consequence, when the partition function results in very large polynomials, the accuracy of the results can be increased, since less drastic truncation of the polynomials (or even no truncation) is necessary. We apply the procedure to the 2D Ising model in a square lattice, obtaining very accurate results for the critical temperature and some of the critical exponents of the model. We also show the results obtained when the technique is used with the Monte Carlo simulated 2D Ising model in large lattices.

Methodological procedure of diagnosing behavioural stereotypes resilience of different language cultures representatives

This paper represents the methodological procedure of diagnosing behavioural stereotypes resilience of different language cultures representatives. The methodological procedure is aimed at compiling a typology of narrative codes of stereotypes resilience of four language cultures representatives and it involves the implementation of six successive stages that will help: 1) to compile a list of personal characteristics of respondents involved in the survey; 2) to compile stimulus lists, i.e. markers of expressive narratives (by keywords); 3) to enter the compiled stimuli lists into the Google Forms with corresponding guidelines for respondents; 4) to perform a free associative experiment with the British, French, Germans and Ukrainians of different social groups through electronic communication; 5) to do the computer processing of the obtained results with the involvement of the information-analytical service STIMULUS; 6) to differentiate the degree of stereotypes resilience of separate social groups of each studied linguoculture in situations of expressive narratives, and differentiate linguistic cultures according to three types of their resilience and their degrees of adaptation to stressful phenomena.

The representation of the Spanish Crown in the public sphere through institutional acts

The main objective of this work is to analyse how the representation in the public sphere of the Crown and the Head of the Spanish State is managed towards public opinion through public, official, and unofficial institutional acts, as reported by the House of H. M. the King. To answer the research questions contained in this objective, a quantitative methodological design based on content analysis is carried out (Krippendorff, 2002). This is applied to a corpus of the 996 public, official, and unofficial acts, contained in the web institution of the House of H. M. the King, between 2015 and 2019, for its subsequent computer processing with SPSS statistical software. Through the concept of intramethod triangulation, a qualitative analysis is applied in an auxiliary way to answer RQ3. The results show not only that the presence of the Royal Family, in the acts observed, contributes towards the public staging of its constitutional functions, but also that there is a map of specific audiences on which the Royal House projects pertinent legitimising messages (regarding the Crown and the Head of State) based on perceived social demands. This confirms the existence of a dialogical communication system, supported by a strategic conception of Crown-society relations, which is resolved mainly through ceremonial acts.
