NUMERICAL-ANALYTICAL METHOD OF DECOMPOSITION-AUTOCOMPENSATION FOR SOLVING THE SIGNAL RECOGNITION PROBLEM BASED ON INACCURATE OBSERVATIONS
Authors: Bulychev Y. G.
Published: November 2024

A numerical-analytical method is developed to solve the problem of optimal recognition of a set of possible signals observed as an additive mixture containing not only a fluctuation observation error (with an unknown statistical distribution) but also a singular interference (with parametric uncertainty). The method allows for both the detection of signals present in the mixture and the estimation of their parameters within a specified quality criterion and associated constraints. The proposed method, based on the idea of generalized invariant-unbiased estimation of linear functional values, enables decomposition of the computational procedure and autocompensation of singular interference without resorting to the traditional expansion of the state space. Linear spectral decompositions in specified functional bases are used for the parametric finite-dimensional representation of signals and interference, while knowledge of the correlation matrix of the observation error is sufficient for error description. Random and systematic errors are analyzed, and an illustrative example is provided.

Authors: Tikhomirov S. B , Shalgin V. S
Published: November 2024

Various iterative algorithms for solving the linear equation ax = b using a quantum computer operating on the principle of quantum annealing are studied. Assuming that the result produced by the computer is described by the Boltzmann distribution, conditions under which these algorithms converge are obtained and an estimate of their convergence rate is provided. Application of this approach for algorithms that use an infinite number of qubits and a small number of qubits is considered.
ON THE STRUCTURE OF HELICAL AXISYMMETRIC SOLUTIONS OF THE NAVIER-STOKES SYSTEM FOR INCOMPRESSIBLE FLUIDS
Authors: Galkin V. A.
Published: November 2024

A class of exact solutions to the Navier-Stokes equations for axisymmetric vortex flows of incompressible fluids is obtained. Invariant manifolds of flows with rotational symmetry relative to a given axis in three-dimensional coordinate space are identified, and the structure of the solutions is described. It is established that typical invariant regions of such flows are rotational figures homeomorphic to a torus, forming a structure of topological fibration, such as in a sphere, cylinder, and more complex configurations composed of such figures. The results are extended to similar solutions of the magnetohydrodynamics (MHD) system and Maxwell’s electrodynamics equations, which possess ℝ3 analogous properties. Examples of axisymmetric vortex vector fields and the topological fibrations they generate on manifolds invariant ℝ3 under the dynamical systems defined by these fields are provided.

IDENTITIES FOR MEASURES OF DEVIATIONS FROM SOLUTIONS OF PARABOLO-HYPERBOLIC EQUATIONS
Authors: Repin S. I
Published: November 2024

The article presents integral identities that hold for the difference between the exact solution of the initial-boundary value problem for a parabolo-hyperbolic equation and any function from the corresponding energy class. These identities allow for the derivation of two-sided a posteriori estimates for approximate solutions to the corresponding Cauchy problem. The left side of the estimate provides a natural measure of deviation from the solution, while the right side depends only on the problem data and the approximate solution itself, making it computable. The obtained estimates are utilized to compare solutions of Cauchy problems for both the parabolic equation and the parabolo-hyperbolic equation with a small parameter in the second time derivative. Additionally, the estimates enable a quantitative assessment of the effects arising from inaccuracies in initial data and coefficients of the equation.
ON THE STABILITY OF A STABILIZING CORRECTION SCHEME WITH CENTRAL DIFFERENCES FOR SPATIAL VARIABLES IN THE 3D TRANSPORT EQUATION
Authors: Zhukov V. P
Published: November 2024

It is generally accepted that the stabilizing correction scheme with central differences for spatial variables in the 3D transport equation is conditionally stable. The work shows that, strictly speaking, this scheme is absolutely unstable. However, the region of unstable harmonics in the wave vector space and the magnitude of their increments rapidly approach zero as the Courant parameter tends to zero, allowing successful use of this scheme. Therefore, it is more accurate to refer to this scheme as practically conditionally stable.
CALCULATION OF PLASMA HEATING BY CHARGED PRODUCTS OF THERMONUCLEAR REACTIONS BASED ON A SIMPLIFIED FOKKER–PLANCK EQUATION
Authors: Khishchenko K. V , Charakhchyan A. A
Published: November 2024

A two-time-layer scheme has been developed for solving the simplified kinetic Fokker–Planck equation related to the transport of charged products of thermonuclear reactions, which includes an interpolation procedure in four-dimensional grid space. Instabilities in the scheme were detected at low particle velocities and for a specific choice of particle deceleration in the ion field, which enters the kinetic equation as a parameter. It was shown that the thermalization condition, which prohibits solving the kinetic equation for particles with energy lower than the average ion energy, significantly limits the number of thermonuclear reactions where instability can manifest. The scheme was tested on the problem of relaxation to a stationary state and on a problem with a prescribed time-dependent thermonuclear reaction rate, for which an exact solution to the kinetic equation can be found.
EXISTENCE AND UNIQUENESS OF SOLUTIONS OF NONLINEAR FUNCTIONAL INTEGRAL ITOˆ EQUATIONS
Authors: Kadiev R. I. , Ponosov A. V.
Published: November 2024

A new class of Ito^ integral equations is considered, which contains many classical problems, for example, the Cauchy problem for differential equations of integer and fractional order with and without stochastic perturbations, as well as some less known and little-studied types of equations that have been introduced recently. The purpose of the study is to find sufficiently general conditions that guarantee the existence and the uniqueness of solutions to such equations, taking into account their specific features. The article therefore proposes to use a special generalized Lipschitz condition, which, due to its flexibility, allows one to obtain effective solvability criteria in terms of the right-hand sides of equations. Numerous examples are considered, covering in particular Ito^ differential equations of fractional order with aftereffect and without aftereffect, equations with fractional Wiener processes, Ito^ equations with several time scales, as well as their generalizations.
INTEGRO-DIFFERENTIAL EQUATIONS IN THE PROBLEM OF ELECTROMAGNETIC WAVE SCATTERING ON A DIELECTRIC BODY COVERED WITH GRAPHENE
Authors: Smirnov Yu. G. , Kondyrev O. V.
Published: November 2024

We consider the determination of resonance frequencies of dielectric bodies coated with graphene. In the addressed problem statement, the graphene nonlinearity is not taken into account. The initial boundary-value problem for Maxwell’s equations is reduced to a system of integro-differential equations on the graphene surface. We prove the Fredholm property of this system under certain sufficient conditions and establish the discreteness of the spectrum of an operator-valued function corresponding to this system in a certain region of the complex plane of the circular frequency spectral parameter.
CONVERGENCE OF THE METHOD OF PIECEWISE LINEAR APPROXIMATIONS AND COLLOCATIONS FOR A TWO-DIMENSIONAL HYPERSINGULAR INTEGRAL EQUATION ON A SET WITH BOUNDARY
Authors: Setukha A. V.
Published: November 2024

A hypersingular integral equation on a convex bounded set on the plane with an integral understood in the sense of a finite part in the sense of Hadamard is considered. Equations of this type, in particular, arise when solving the Neumann boundary value problem for the Lapalse and Helmholtz equations on a flat screen in the case where the solution is sought in the form of a double layer potential. To numerically solve the equation, a numerical scheme is used based on piecewise linear approximation of the unknown function on a triangular conformal mesh and the collocation method. The uniform convergence of numerical solutions to an exact solution on a grid when the maximum cell diameter tends to zero has been proven.

CONTROL DESIGN FOR A MULTIDIMENSIONAL SYSTEM OF ORDINARY DIFFERENTIAL EQUATIONS WITH RELAY HYSTERESIS AND PERTURBATION
Authors: Yevstafyeva V. V
Published: November 2024

A multidimensional controllable system with a constant matrix, a significant nonlinearity of the twoposition relay type with hysteresis as a control and a continuous periodic perturbation function is considered. The system matrix has simple, real, non-zero eigenvalues, among which one can be positive. Conditions for the system parameters, including the nonlinearity ones, are established under which there is a single two-point oscillatory periodic solution with a period comparable to the period of the perturbation function in the case of a special type of the feedback vector. The asymptotic stability of the solution has been proven using the phase plane method. The results obtained are illustrated by examples for three-dimensional systems.

Authors: Apushkinskaya D. E , Novikova A. A , Repin S. I
Published: November 2024

The paper is concerned with a functional identity and estimates which are fulfilled for the measures of deviations from exact solutions of the obstacle problem for the 𝑝-Laplacian. They hold true for any functions from the corresponding (energy) functional class, which contains the generalised solution of the problem as well. We do not use any special properties of approximations or numerical methods nor information of the exact configuration of the coincidence set. The right-hand side of the identities and estimates contains only known functions and can be explicitly calculated, and the left side represents a certain measure of the deviation of the approximate solution from the exact solution. The right-hand side of the identity and estimates contains only known functions and can be explicitly calculated, while and the left side represents a certain measure of the deviation of the approximate solution from the exact one. The obtained functional relations allow to estimate the error of of any approximate solutions of the problem regardless of the method of their obtaining. In addition, they enable to compare the exact solutions of problems with different data. The latter provides the possibility to estimate the errors of mathematical models.

Published: November 2024

Abstract—The process of sorting tomatoes can be done using visual methods by paying attention to color. The purpose of this research is to improve the process of sorting tomatoes based on color in distinguishing ripe tomatoes and immature tomatoes. Streamline the time of sorting tomato fruit in order to avoid losses due to spoilage. This research method is with a sample of tomato fruit taken RGB value through TCS 3200 color sensor according to the level of maturity. After the RGB value is obtained, it will be processed into the Arduino Uno to obtain maturity information through the rules that have been made and sorted using a servo motor. The results of this study indicate that a good condition for detecting tomato fruit is with a closer distance to the fruit with a dark background. This is because there is no excess light reflection so that the TCS sensor can take RGB values well and reduce the occurrence of misreading of ripeness information in the sorting process.
Keywords— Tomato, Sensor TCS 3200, Arduino uno, Motor Servo.

Published: November 2024

Gronwall's inequalities are important in the study of differential equations and integral inequalities. Gronwall inequalities are a valuable mathematical technique with several applications. They are especially useful in differential equation analysis, stability research, and dynamic systems modeling in domains spanning from science and math to biology and economics. In this paper, we present new generalizations of Gronwall inequalities of integral versions. The proposed results involve $( \rho ,\varphi)-$Riemann-Liouville fractional integral with respect to another function. Some applications on differential equations involving $( \rho ,\varphi)-$Riemann-Liouville fractional integrals and derivatives are established.
Farmacologia e Filosofia da Tecnologia: A contribuição do diálogo Fedro de Platão
Authors: Aguiar Carlos Eduardo
Published: November 2024

Fedro de Platão é o modelo paradigmático da reflexão crítica sobre a técnica, pois denuncia o caráter maléfico da escrita, destacando seus efeitos prejudiciais, especialmente ao promover o esquecimento, corromper a construção do conhecimento e forjar um simulacro de comunicação. Este artigo tem como objetivo analisar Fedro explorando a reflexão de Jacques Derrida que interpreta que, para Platão, a escrita é, acima de tudo, um phármakon, simultaneamente remédio e veneno. Enfatiza-se, assim, a fascinação provocada pela escrita, sua capacidade de transformar a ecologia social e desterritorializar o território, mas também a tendência da escrita em causar perturbações na efetivação do diálogo e o encontro com o outro. Os elementos que emergem dessa reflexão evidenciam a não neutralidade da tecnologia, enfatizando a abordagem farmacológica como uma contribuição relevante para o debate sobre o caráter não instrumental das técnicas presentes na filosofia da tecnologia contemporânea.
O sofrimento dos animais não humanos e o paradoxo do mal natural
Authors: Braga Lourenço Daniel
Published: November 2024

O presente trabalho investiga o paradoxo envolvendo o problema do mal, especialmente o sofrimento que ocorre em função de fenômenos naturais (mal natural). Os animais não humanos sencientes são criaturas inocentes que sofrem em abundância em decorrência desses eventos. Como explicar a existência desse mal, que provoca perda relevante do bem-estar experimental e tormento gratuito a esses seres, diante do conceito tradicional de um Deus onisciente, onibenevolente e onipotente? O argumento do mal, na sua abordagem do mal natural, constitui a ameaça mais fundamental ao conceito tradicional da existência de Deus.
As máquinas podem cuidar?
Authors: Carvalho Eros
Published: November 2024

Aplicações e dispositivos de inteligência artificial são cada vez mais comuns na área da saúde. Robôs que cumpram algumas funções de cuidado não são um futuro distante. Neste cenário, temos de nos perguntar se é possível máquinas capazes de cuidar a ponto de substituírem completamente o cuidado humano e se essa substituição, em sendo possível, é desejável. Neste artigo, argumento que o cuidado requer saberes-fazeres permeados por afetividade que estão longe de serem realizados pelas máquinas atualmente disponíveis. Sustento também que a substituição completa do cuidado realizado por humanos por cuidado realizado por máquinas não é desejável porque o cuidado requer conexão humana real.

Gamificação como instância da reontologização tecnológica
Authors: Frambach Danilo
Published: November 2024

O presente trabalho pretende examinar a relação da gamificação com o processo de reontologização do mundo promovido pelo avanço tecnológico, como proposto por Floridi. Tal processo reconfiguraria a natureza do mundo de forma que elementos artificiais e digitais passam a ser compreendidos como possuidores de agência. Nossa hipótese se apresenta da seguinte maneira: (a) o processo de reontologização só pode ocorrer quando assumimos uma visão solucionista do mundo; (b) a gamificação possui elementos claros de solucionismo, e enquanto elemento tecnológico, é parte dessa reontologização; e dessa forma, (c) a gamificação acaba sendo apropriada pelo capitalismo como forma de ocultar processos exploratórios atrás de elementos de jogo. Assim, o artigo pretende concluir com uma análise da metáfora da brumificação, como uma forma pela qual as Big techs se utilizam da gamificação.
Trans-humanismo: de movimento intelectual à corrente filosófica
Authors: Hahn Paulo , França Cleverson Luiz
Published: November 2024

O sonho de transcender as limitações humanas remonta a contos e histórias com séculos de existência. Isto fomentou o surgimento do movimento trans-humanista, um movimento multifacetado, também com séculos de existência, propulsor da filosofia trans-humanista, a qual defende o uso de tecnologias avançadas para melhorar a condição humana e superar limitações biológicas, como envelhecimento ou limitações intelectuais. Com suas raízes no Iluminismo e no Humanismo, o humanismo propõe uma evolução contínua da vida inteligente, guiada por princípios de racionalidade e ética que respeitem a liberdade individual e assegurem o bem-estar a toda senciência. A implementação desses ideais requer que os avanços tecnológicos sejam amplamente acessíveis e seguros, evitando riscos existenciais e promovendo uma sociedade organizada, informada e livre, para que suas escolhas acerca dos rumos que as tecnologias de melhoramento humano possam ser justas, plurais e inclusivas.

Staged Dissent – »Change My Mind« as a Vehicle of Instrumental Deliberation within the Identitäre Bewegung Österreich
Authors: Trochemowitz Jonas , Herford Lara
Published: November 2024

In this paper we aim to analyze the talking format of Change my Mind by Steven Crowder and its adaptation by the former spokesperson of the right-wing extremist group Identitäre Bewegung in Austria. By employing the concept of ›genre of dissent‹ we ask the question how democratic values of deliberation are strategically used to gain legitimacy for far-right positions in discourse. A key aspect is how these strategies relate to practices of self-marginalisation in the sense of mimicry of marginality. As a model for dismantling and criticising these practices we suggest the concept of instrumental deliberation
»Everything a Learner Needs« – Constructions Of Linguistic and Social Marginality/Centrality In Discourses about (German) Language Learning and Multilingualism
Authors: Mattfeldt Anna
Published: November 2024

The paper deals with discursive portrayals of language learning and language learners. In a combination of quantitative and qualitative approaches, it asks whether the status of the language learner is constituted as a phenomenon of marginality or of centrality in current discourses in Germany, and whether this may in some instances be seen as a mimicry of marginality. The qualitative part of the analysis takes positionings by learners and native speakers into account, considering linguistic ways of constituting both the self and others with regard to language(s) and learning. The paper also discusses whether the status transition of a person from learner to language »expert« is depicted as possible, and whether learning a language offers a form of prestige.
»My Wallet, My Choice« – Mimicry of Marginality In an Online Community of Male Separatists
Authors: Aiston Jessica
Published: November 2024

Backlash and hostility towards feminism are on the rise, as demonstrated by the growth of the ›manosphere‹: a loose network of men’s social media communities who argue that men are the real victims of sexism and feminists conceal these facts (Ging 2019). One manosphere group, »Men Going Their Own Way« (MGTOW), argue that heterosexual relationships are oppressive to men and consequently should be avoided. In this paper, I take a discourse-historical approach to critical discourse studies (Reisigl/Wodak 2016) to examine how MGTOW construct themselves as marginalised or oppressed. I identify four salient discursive strategies: appropriation of feminist discourse; role reversal; statistics; and self-presentation as unpopular.

Published: November 2024

Nagari Magek Village in Agam Regency, West Sumatra, faces significant challenges in managing clean water resources. To address these challenges comprehensively, a holistic approach is essential, involving through area analysis, water treatment, and evaluation of distribution networks to ensure efficient and equitable water distribution. It is crucial to adhere to the principles of water resource conservation, utilization, and management as stipulated in Law Number 17 of 2019 on water resource management, which must be observed to ensure legal clarity in water management practices. The community service team handles clean water problems in Nagari Magek by designing a clean water treatment system that includes aeration, sedimentation, and filtration units. This process improves water quality by reducing yellowish color and eliminating unpleasant odors. However, the capacity of the treatment plant is not able to meet the increasing water demand, while the galvanized pipe distribution network has not been functioning optimally. Based on simulations using EPANET 2.2 software, it was found that the water flow speed in the pipes was still below the optimal range due to the diameter of the pipes being too large. The solution applied was to increase the processing discharge to 10 L/s (0,01 m3/s), which succeeded in increasing the flow rate according to the regulatory criteria. This recommendation improves the efficiency of the distribution system and ensures better water quality for the people in Nagari Magek.

This study primarily aimed to establish an uncomplicated yet highly responsive HPLC technique to effectively separate and quantify process-related impurities of Lemborexant. Additionally, it aimed to explore the forced degradation behavior of lemborexant through systematic assessments by utilizing LCMS. The chromatographic separation of drug substance, process related impurities and its degradation products (DPs) was achieved on Kinetex C18 (150×4.6 mm, 5 μm) column at that was maintained at 350C temperature using 10 mM ammonium formate buffer pH 4.2, acetonitrile and methanol in 65:25:10 (v/v) isocratic elution at 0.7 mL/min. Detection wavelength was selected as 265 nm. In the proposed conditions, lemborexant is identified at 4.06 and 6.19, 9.33 min and 1.60 min respectively for impurity 1, 2 and 3 min with acceptable system suitability and specificity. The method produces LOD at 0.009 for impurities with calibration range of 40–280 µg/mL for lemborexant and 0.04 - 0.28 µg/mL for impurities. The remaining validation parameters were observed to fall within acceptable ranges for both lemborexant and its impurities. The compound underwent exposure to various stress conditions (acid, base, peroxide, thermal, and UV light) as outlined in accordance with ICH Q1A (R2) guidelines. The degradation products formed during the stress study were detected and characterized using LCMS/MS in ESI positive mode. This involved a thorough comparison of collision-induced dissociation mass spectrometry data between the degradation products and lemborexant. Consequently, potential structures for five degradation compounds were proposed. The outcomes of supplementary validation investigations were equally satisfactory, confirming their appropriateness for the regular quantification of lemborexant and its related impurities in both bulk drug and pharmaceutical formulations. Furthermore, these findings have the potential to shed light on the mechanism of stress-induced degradation in lemborexant

In this work, of New Ligand [(E)-5-hydroxy-4-(3-(4-methoxy phenyl) acryl amido) naphthalene -1- sulfonic acid] (ANS) was prepared by reflexing reaction of 4-amino-5-hydroxy naphthalene sulfonic acid with para methoxy cinnamic acid, this produced and described chemical was employed as ligand to prepare tri and di-organotin complexes by condensation reaction with the salts of organotin chloride (phenyl, butyl, and methyl tin chloride). Specialized methods, including elemental analysis, (tin and proton) magnetic resonance, and infrared spectra, were used to identify the complexes. DPPH (2,2-diphenyl-1-picrylhydrazyl) and CUPRAC (Cupric Reducing Antioxidant Capacity) are both commonly used methods for measuring antioxidant capacity in various samples. Due to the tin moiety, the produced tri and di-tin complexes gave higher percentage inhibition than the ligand in both techniques; also, the triphenyltin complex performed the best when compared to the others. The results of this study are expected to contribute to the understanding of the structure-activity relationship of organotin complexes and their potential as antioxidants, which may have implications for developing novel therapeutic agents with antioxidant properties.

This rapid economic change causes the currency exchange rate to fall and the price of basic necessities to increase. The Ordinary Least Square (OLS) method is used to assess the trade balance due to the economic crisis, and the export growth of Indonesia's export destination countries will weaken as a result of the crisis. The domestic purchasing power of Indonesia's export destination countries has also declined as a result of the crisis. Secondary data published by BPS for the period 2013–2022 were used in this study. The data was processed using the SPSS V.27 program, which shows that Indonesia's trade balance cannot be separated from exchange rates, inflation, and interest rates, so that all three variables have an impact on the trade balance simultaneously. The estimation of the trade balance model in Indonesia shows that each independent variable—exchange rate, inflation, and interest rate—has a partial effect on the country's trade balance. The greatest influence of this variable was 57.22% on the country's trade balance, and other variables that were not discussed in the study.
