Method of Riesz potentials applied to solution to nonhomogeneous singular wave equations
Authors: Shishkina E.L. , Abbas S.
Published: March 2023

Riesz potentials are convolution operators with fractional powers of some distance (Euclidean, Lorentz or other) to a point. From application point of view, such potentials are tools for solving diﬀerential equations of mathematical physics and inverse problems. For example, Marsel Riesz used these operators for writing the solution to the Cauchy problem for the wave equation and theory of the Radon transform is based on Riesz potentials. In this article, we use the Riesz potentials constructed with the help of generalized convolution for solution to the wave equations with Bessel operators. First, we describe general method of Riesz potentials, give basic deﬁnitions, introduce solvable equations and write suitable potentials (Riesz hyperbolic $B$-potentials). Then, we show that these potentials are absolutely convergent integrals for some functions and for some values of the parameter representing fractional powers of the Lorentz distance. Next we show the connection of the Riesz hyperbolic B-potentials with d’Alembert operators in which the Bessel operators are used in place of the second derivatives. Next we continue analytically considered potentials to the required parameter values that includes zero and show that when value of the parameter is zero these operators are identity operators. Finally, we solve singular initial value hyperbolic problems and give examples.

Published: March 2023

Локальные краевые задачи для уравнений с меняющимся направлением времени исследовались во многих работах. Разрешимость нелокальных по времени краевых задач изучалась для параболических уравнений второго порядка. Для неклассического уравнения третьего порядка была рассмотрена регулярная разрешимость краевых задач с интегральными граничными условиями по времени. В данной работе в цилиндрической области пространства $R^{n+1}$ исследуется краевая задача с интегральным граничным условием по времени для уравнения нечетного порядка с меняющимся направлением времени. При определенных условиях на коэффициенты уравнения и данные краевой задачи доказана регулярная разрешимость рассматриваемой нелокальной краевой задачи. В доказательстве регулярной разрешимости данной нелокальной краевой задачи используется вспомогательная локальная краевая задача для уравнения нечетного порядка с меняющимся на-правлением времени. Также для вспомогательной краевой задачи получена оценка сходимости, с помощью которой установлена оценка сходимости приближенных решений к точному решению рассматриваемой нелокальной краевой задачи.

Local boundary value problems for equations with changing time direction have been studied in many papers. The solvability of nonlocal in time boundary value problems was studied for second order parabolic equations. For a third-order non-classical equation, the regular solvability of boundary value problems with integral boundary conditions over time was considered. In this paper, in a cylindrical domain of $R^{n+1}$, we study a boundary value problem with an integral boundary condition in time for an equation of odd order with changing time direction. Under certain conditions on the coefficients of the equation and the data of the boundary value problem, the regular solvability of the nonlocal boundary value problem under consideration is proved. Proving the regular solvability of the given non-local boundary value problem, we introduce an auxiliary local boundary value problem for an equation of odd order with changing time direction. Also, for the auxiliary boundary value problem, a convergence estimate is obtained, which is used to establish an estimate of the convergence of approximate solutions to the exact solution of the nonlocal boundary value problem under consideration.
A coupled dual continuum and discrete fracture model for subsurface heat recovery with thermoporoelastic effects
Authors: Ammosov D. , Vasilyeva M. , Babaei M. , Chung E.
Published: March 2023

We consider heat recovery from geothermal fractured resources with thermo-poroelastic effects. To this end, a hierarchical fracture representation is considered, where small-scale highly connected fractures are represented by the classical dual porosity model whereas large scale dense fractures are represented by the discrete fracture model. The mathematical model is described by a system of equations for mass and heat transfer for coupled dual continuum model as well as discrete fractures. Geomechanical deformations are written in the general form. For numerical solution of the resultant coupled system of equations including multicontinuum temperatures, pressures and deformations, we use the finite-element method. Numerical results are presented for two- and three-dimensional examples, showing applicability of the proposed method.

The intervention was aimed at reversing the declining consumption of millet, which was primarily due to inconvenience in its preparation as direct food. Thus diversifications of processing technologies related to millet products were attempted, to remove the inconveniences and to develop, fine-tune and standardize millet product technologies. For this purpose, the new trends of food processing involved the primary processing and secondary processing methods have been developed more products, such as extruded products (vermicelli and pasta), flakes, savouries, nutribar, and biscuits etc. These products were made ready for commercialization with improved shelf life. Processing interventions in millet products were good acceptability with improved nutritional value, convenience and shelf life. They are being continued for invention of innovative products of millet and target both niche markets such as gluten-free products; health mix products for mass-markets at the national level. One of the most relevant millet interventions was promotion; creating awareness of the health and nutritional merits of millet products and reinventing them as popular, convenient and healthy foods.
Systematic study of the nanostructures of exfoliated polymer nanocomposites
Authors: Espíndola Suellen Pereira , Zlopasa Jure , Picken Stephen J.
Published: March 2023

High-performance bioinspired materials have shown rapid development over the last decade. Examples are brick-and-mortar hierarchical structures, which are often achieved via solvent evaporation. Although good properties are claimed, most systems are composed of stacked or intercalated platelets. Exfoliation is a crucial step to give ultimate anisotropic properties, e.g. thermal, mechanical and barrier properties. We propose a general framework for all the various types of micro-scale structures that should be distinguished for 2D-filler nanocomposites. In particular, the exfoliated state is systematically explored by the immobilization of montmorillonite platelets via (gelatin) hydrogelation. Scattering techniques were used to evaluate this strategy at the level of the particle dispersion and the regularity of spatial arrangement. The gelatin/montmorillonite exfoliated nanostructures are fully controlled by the filler volume fraction since the observed gallery d-spacings perfectly fall onto the predicted values. Surprisingly, X-ray analysis also revealed short- and quasi long-range arrangement of the MMT at high loading.
Describing proton transfer modes in shared proton systems with constrained nuclear-electronic orbital methods
Authors: Zhang Yuzhe , Xu Xi , Yang Nan , Chen Zehua , Yang Yang
Published: March 2023

Abstract Proton transfer is crucial in various chemical and biological processes. Because of significant nuclear quantum effects, the accurate and efficient description of proton transfer remains a great challenge. In this communication, we apply constrained nuclear-electronic orbital density functional theory (CNEO-DFT) and constrained nuclear-electronic orbital molecular dynamics (CNEO-MD) to three prototypical shared proton systems and investigate their proton transfer modes. We find that with a good description of nuclear quantum effects, CNEO-DFT and CNEO-MD can well describe the geometries and vibrational spectra of the shared proton systems. This good performance is in great contrast to DFT and DFT-based ab initio molecular dynamics, which often fail for shared proton systems. As an efficient method based on classical simulations, CNEO-MD is promising for future investigations of large and more complex proton transfer systems.

Published: March 2023

The quintet triplet-pair state generated upon singlet fission is a critical intermediary that dictates the fate of excitons which can be exploited for photovoltaics, information technologies and biomedical imaging. In this report, we demonstrate that continuous wave and pulsed electron spin resonance techniques such as PEANUT, which have emerged as the primary tool for identifying the spin pathways in singlet fission, probe fundamentally different triplet pair species. We directly observe that the generation rate of high-spin triplet pairs is dependent on the molecular orientation with respect to the static magnetic field. Moreover, we demonstrate that this observation can prevent incorrect analysis of cw-ESR measurements, and provide insight into the design of materials to target specific pathways which optimise exciton properties for specific applications.

Published: March 2023

Utilizing four-dimensional scanning ultrafast electron microscopy (4D-SUEM) is a powerful tool to monitor charge dynamics at material surfaces and interfaces especially for the application in renewable energy field. Herein, we uncover unique physical features for 4D-SUEM upon reducing the acceleration of probed primary electrons to 1 keV, for wide range of materials including various single crystals, thin films and quantum dots upon the presence of oxidized and neat surfaces. Working at 1 keV helps to uncover the migration of photogenerated carriers originating from both sub-surface and bulk layers, under the influence of the carriers scattering and the band-bending phenomena. This approach provides a new avenue for the spatial and temporal access to the surface exclusive dynamics in renewable energy materials to unlock their interfacial behaviors at the nanoscale level.
Ab initio investigation of the Auger spectra of methane, ethane, ethylene, and acetylene
Authors: Matz Florian , Nijssen Jonas , Jagau Thomas
Published: March 2023

We present an ab initio computational study of the Auger spectra of methane, ethane, ethylene, and acetylene. Auger spectroscopy is a established technique to probe the electronic structure of molecules and exploits the Auger-Meitner effect that coreionized states produced by X-ray irradiation undergo. We compute partial decay widths for the relevant decay channels using coupled-cluster theory with single and double substitutions (CCSD) and equation-of-motion-CCSD theory combined with complex-scaled basis functions and Feshbach-Fano projection. We generate Auger spectra from these partial widths and draw conclusions about the strength of particular decay channels and trends between the four molecules. A connection to experimental results about fragmentation pathways of the electronic states produced by Auger decay is also made.
Tuning structural coloration through evanescent wave absorption at microscale concave interfaces
Authors: Hirsch Krista , Sturniolo Nathaniel , Meredith Caleb , Rayes Malak , Zarzar Lauren
Published: March 2023

Here, structural color generated by total internal reflection (TIR) interference at microscale concave interfaces is tuned via evanescent wave absorption by dyes. Using quantitative angle-resolved spectral analysis combined with ray tracing simulation, it is demonstrated that the multibounce TIR trajectories enhance the efficiency of dye absorption and usefulness in modulating the reflected colors. Depending on the absorbance spectrum of the dye used, and the amount of dye coated at the TIR interface, the angle-dependent reflected colors can be predictably altered. The use of a near-infrared absorbing dye allows for the combination of overt color-shifting iridescent effects under illumination with visible wavelengths and covert optical-motion effects under near-infrared. This work, which explores an innovative approach for controlling the reflective properties of iridescent structurally colored materials, may be of interest both for fundamental research and for applications such as sensors, coatings, and security.

Published: March 2023

Flipped classroom is a sort of blended learning in which students learn both synchronously and asynchronously. Synchronous learning has taken place in the classroom in real time. Learners gather feedback while communicating with teachers and classmates at the same time. This review expects to figure out how is the execution and effect of Flipped Classroom in Science Learning (Contextual analysis During the Covid-19 Pandemic) of Class VIII at SMPN 3 Rantau Bayur. This study used a case study as an approach in exploring qualitative data. This examination is a distinct subjective exploration as a contextual analysis with information assortment methods as polls and meetings. The results of this review demonstrate that the execution and effect of flipped classroom in science learning during the Covid-19 pandemic is positive, particularly for class VIII students in science subjects at SMPN 3 Rantau Bayur with a typical rate gain of 76.7% or the category of ‘very good’. Through the flipped classroom, students have the opportunity to concentrate on the topic at home as they are free to set their learning time. Students become familiar with the topic in an enjoyable situation. Students can repeat the learning videos and they are able to access them from anywhere. Besides, parents can participate in learning activities outside the classroom and make time to help their children learn. However, one of the drawbacks is the lack of devices to watch videos given by the teacher as not all students have computers, laptops, or smartphones. Also, the teachers still find difficulties in preparing good quality videos as learning media for students.

Dois princípios fundamentais. — Tôda reflexão sobre os Seminários ou sôbre a formação que nêles convém ministrar comporta duas referências: uma às diretrizes da Igreja e outra às realidades do mundo no qual deve o padre exercer sua atividade.

Com efeito, não é possível, quando se trata do padre e de sua preparação, querer abstrair daquilo que a Igreja viu e disse no Concílio. Foi há pouco tempo, e não podemos pensar que tenham bastado os últimos três anos para fazer caducar um juízo que era o da universalidade do Episcopado e garantido pelo socorro extraordinário de Deus à sua Igreja oficialmente reunida. Tôda discussão ou reflexão que julgasse não precisar levá-lo em conta se encontraria fora do clima normal de pesquisa em que a graça de Deus ilumina a sua Igreja...

The quality of spring waters in the district of MADIBOU located south of Brazzaville was evaluated by physicochemical and microbiological parameters measured in situ or in the laboratory. The waters from all springs studied are cleared and did not present an unpleasant smell. The survey conducted among the population in the study area showed that 70.5 to 85.33% of the inhabitants use spring water. The water springs directly from the surface of the ground through an opening made by the inhabitants of the district and appropriate containers are placed at this outlet to collect water which they use without any prior treatment. After sampling the spring water, several analytical methods were used to determine the different parameters. The results of these analyzes show that from a physicochemical quality, these waters are acidic with pH values which are not in the pH range of drinking water and contain amount of nitrates that largely exceed WHO standards, which constitutes a danger for the population that consumes these waters. On the microbiological level, we note the presence of total germs and total coliforms, and the absence of faecal coliforms. The consumption of this water without prior treatment is therefore not recommended ; before using this water, specific treatments must be carried out, for example pH correction with calcium hydroxide and disinfection with sodium hypochlorite.

Published: March 2023

The effectiveness of teachers' use of their metacognitive skills is closely related to the success of the learning process. Nowadays, it is imperative for students to use self-regulatory and metacognitive skills to cope with the changes happening around the world. This study seeks to determine if the metacognitive awareness levels of pre-service teachers vary when they are grouped according to gender and year level. The sample size of this study is 120 pre-service teachers enrolled in a teacher education program at a state university in the Philippines. Two instruments were utilized in this study which are the Personal Information Form and the Metacognitive Awareness Inventory (MAI) adapted from Schraw and Dennison (1994). Generally, results show that pre-service teachers’ metacognitive awareness levels were high. Independent sample t-test result shows that there is a significant difference between the pre-service teachers’ metacognitive awareness when they are grouped according to their gender. Similarly, a statistically significant difference was also found when they were grouped according to year level using one-way ANOVA. The results of this study suggest that teacher training programs should be organized with the objective of promoting the enhancement of metacognitive awareness knowledge and skills of pre-service teachers. Having high metacognitive awareness can improve the learning experience of the students; thus, it minimizes the difficulties that they may encounter. For the increased validity of the study, it is recommended to use a qualitative research approach.

Estimation of Urban Area Change in Eskişehir Province Using Remote Sensing Data and Machine Learning Algorithms
Authors: Küçük Matcı Dilek
Published: March 2023

Rapid population growth, natural events, and increasing industrialization are among the factors affecting land use. To keep this change under control and to make sound plans, it is necessary to control the changes. In this study, the spatial use change in the Eskişehir region between the years 1990-2018 was examined with CORINE data. Based on this determined change, an urban change model was created with the multivariate regression method. As a result of the evaluations, while an increase was observed in urban areas and pastures between 1990-2018, a decrease was determined in agricultural and forest areas. This change is defined as 43.74% in urban areas, 3.28% in agricultural areas, 7.78% in forest areas, and 60.10% in pasture areas. SMOReg, MLP Regressor, and M5P Model Tree methods were used for the estimation study to be carried out with the obtained spatial change data. Urban values for 2018 were estimated to find the best method. Finally, the areas of 2030 were estimated with the method that gave the best results. The results demonstrated the usability of modeling using CORINE data.

Published: March 2023

En este artículo se discute el uso de sistemas de decisión de soporte basados en minería de datos (para la evaluación histórica) y máquinas de vectores de soporte, con la finalidad de obtener los valores óptimos relacionados con la eficiencia de enfriamiento en un álabe de turbina de gas para determinar la adecuada selección de componentes y construir escenarios bajo incertidumbre. Esta investigación permite seleccionar un número específico de componentes, los cuales son evaluados a partir de un depósito de información con datos de otro sistema de energía. La intención de la presente investigación es aplicar propiedades computacionales, en este caso un modelo de optimización inteligente. El caso de estudio permite analizar las características individuales de cada componente con la emulación de una serie de características correspondientes (valores óptimos alcanzados por el algoritmo híbrido). De esta manera es posible predecir una mejor funcionalidad en un sistema de este tipo.
Implementación del clasificador naive Bayes para la acentuación automática de palabras ambiguas del español
Authors: González Meneses Yesenia Nohemí , Pedroza Méndez Blanca Estela , López Briones Francisco , Pérez Corona Carlos , Ramírez Cruz José Federico
Published: March 2023

En este artículo se analiza uno de los problemas más representativos en el tratamiento del lenguaje español, que es el de la ambigüedad en la acentuación gráfica de las palabras. En la escritura del español se utiliza el acento gráfico o tilde, el cual determina la pronunciación o interpretación correcta de las palabras. Algunos vocablos de construcción similar pueden llevar tilde o no, o la llevan en diferente sílaba, lo cual permite que tomen diferentes sentidos en relación con su contexto, para lo cual se utiliza la llamada tilde diacrítica. La asignación correcta de la tilde diacrítica en este proyecto es abordada como un problema de clasificación, donde con base en el contexto se determina si las palabras ambiguas llevan esta marca o no. Para ello se entrenó un modelo con el clasificador naive Bayes.

Published: March 2023

Este artículo revisa los beneficios de la programación orientada a aspectos para rastrear la ejecución de los procesos internos de un sistema heredado. Para poder alcanzar dicho propósito es necesario separar la implementación del rastro en una abstracción diferente aislando su código del resto del sistema. Esta aproximación permite enlazar el sistema heredado con las funcionalidades de monitoreo, y es necesario utilizar una capa intermedia que permita enlazarlos. Esta nueva abstracción llamada aspecto maneja solamente lo relacionado con el rastreo y no requiere modificar el código fuente del sistema, con lo cual se reducen costos y dinero para el análisis, diseño y desarrollo.

MODERN PRODUCTION TECHNOLOGIES APPLIED TO VARIOUS LIFE CYCLE PHASES OF PRODUCTS AND MACHINE PARTS
Authors: Oganesyan Oganes , Burlachenko Oleg
Published: March 2023

The study objective is to identify modern production technologies used at almost all phases of the life cycle. To achieve this objective, there have been analyzed and reviewed papers and foreign studies published mainly within 2016-2020 in journals covered by SCOPUS and WoS indexing services, as well as studies of Russian scientists over the past ten years, which are indexed in the above-mentioned international services, as well as in the national RSCI system. The references analyzed in this paper prove that additive technologies are inferior to combined (additive-subtractive, additive-subtractive-hardened, etc.) technologies from the point of view of obtaining high-quality products at the present stage of production development. Conclusions: it is proposed to include the stage of capital repairs and updating of the general model at the stage of modeling the life cycle of machine-building products, which can be the right direction for choosing the most effective technology regardless of the life cycle phase; the choice of technology for the production stage of a particular product or part should be justified in terms of improving the basic operational properties and increase of the residual resource.
