Full textAbstract:
Abstract The paper is devoted to the strength analysis of a simply supported three layer beam. The sandwich beam consists of: two metal facings, the metal foam core and two binding layers between the faces and the core. In consequence, the beam is a five layer beam. The main goal of the study is to elaborate a mathematical model of this beam, analytical description and a solution of the three-point bending problem. The beam is subjected to a transverse load. The nonlinear hypothesis of the deformation of the cross section of the beam is formulated. Based on the principle of the stationary potential energy the system of four equations of equilibrium is derived. Then deflections and stresses are determined. The influence of the binding layers is considered. The results of the solutions of the bending problem analysis are shown in the tables and figures. The analytical model is verified numerically using the finite element analysis, as well as experimentally.

This paper corrects some mistakes about three theorems, two figures and some expressions on “finite field” in a literature, and then it analyzes the digraphs and period properties of the logistic map on residue class rings [Formula: see text] and [Formula: see text]. Some theorems and conjectures are proved or given. To validate these properties, we make some numeral experiments and draw the relative figures and tables. So the theoretical analysis and numeral experiments show that there exists periods in the logistic map on [Formula: see text] and on [Formula: see text] and it can be applied in the pseudo-random generators, cryptography, spread spectrum communications and so on.

Full textAbstract:
The objective of this paper is to present comprehensive lists of accurate natural frequencies of isotropic thin rectangular plates. For this purpose, a simple yet very accurate analytical approach is described to study the free vibration of the plates. In numerical computations, convergence and comparison studies are conducted to check accuracy of the present solution and to demonstrate improvement of numerical solutions in the results. Twenty-one tables are then provided to give the lowest six frequency parameters for all possible combinations of three typical edge conditions (clamped, simply supported and free edges). Each frequency value in the tables is given in five significant figures for non-Levy type problem (i.e., two opposite edges not simply supported) and six significant figures for Levy type problem. These results are presented for five different aspect ratios in the same format of the past representative reference.

Full textAbstract:
A combined control system for a shunt active filter in the coordinate system of the two-wattmeters method has been proposed, which, depending on the conditions of use, implements one of the four active filtration strategies, optimal according to a certain quality indicator. The most promising is the proposed integral strategy for active filtration control with the reference vector of line voltages of direct sequence, which provides symmetric sinusoidal currents of the network and the minimum pulsation of power consumption for the almost identical energy-saving effect as the concept of S. Fryze. New formulas for calculating the energy-saving effect and pulsations of the instantaneous power in a three-phase system of power in the case of the formation of an active current in the transmission line in the conditions of asymmetry of loading voltage and linear asymmetric load have been developed. Simulation studies have confirmed the adequacy of the proposed strategies and calculations. References 15, figures 5, tables 2.

In this paper, A new accurate solutions are obtained for classes of singular two-point boundary value problems (BVPs) using a new solution procedure based on the construction of the auxiliary functions of the standard optimal homotopy asymptotic method (OHAM). This procedure give us accurate approximate solutions using only one order of approximation compared with the solutions obtained previously by the standard OHAM approximation of three order. The obtained numerical results which are displayed in tables and plotted graphically in figures leads to concluded that this procedure is efficient and of third order reliable for finding the solutions of singular two BVPs.

Full textAbstract:
Purpose. To evaluate the results of color vision functions using different methods in amblyopic children and in children of the control group. Material and methods. We observed 81 school children: 1) 35 amblyopic children 2) 46 children of the control group without amblyopia. The color vision was explored using classic tests (polychromatic Rabkin tables and Neitz-test) and our own test images (Patent RU 2760085 dated 02/04/2021). Results. In the control group normal trichromasia was detected in 38 (82.6%) children using all three methods. In the rest of the cases using Rabkin tables revealed difficulties in defining shapes of the test figures in some tables in four (8.7%) children. Nevertheless, the children could name the colors of separate circles composing the images correctly. Using Neitz-test revealed difficulties in 6 (13%) children. Using our own developed tests revealed no difficulties in children of the control group. In the group of amblyopic children normal trichromasia of both eyes was detected only in 12 (34,3%) children using all three methods. Using Rabkin tables, Neitz-test and our own developed tests detected protanopia combined with deuteranopia in two boys under conditions of observing the best seeing eye and the worst seeing eye. Using the same tests detected less expressed disturbances of perception red and green colors in two girls. Nine (25.7%) children could name the colors of separate circles correctly but had difficulties in defining shapes of the test figures in some Rabkin tables. Accomplishing Neitz-test 15 (42.9%) children named the colors of all test figures correctly but made mistakes defining their shapes. Conclusion. Exploring color vision in children using Rabkin tables and Neitz-test it is necessary to consider that these tests make an observed child accomplish two tasks simultaneously – distinguishing the color and defining the shape. Usually, it does not cause any difficulties in a healthy school child. But under conditions of amblyopia the mechanism of integrating the information of the colour and the shape into a united visual image may be disturbed. It complicates the correct accomplishing the test and may cause mistakes in a doctor's interpretation of a patient's answers. Our developed test images do not require defining the chromatic form. It allows them to reflect a child's ability to distinguish a chromatic image from achromatic images of the same brightness and the ability to distinguish shades of basic tones at different degrees of their saturation. Besides, the advantages of the method are simplicity of accomplishing, minimal amount of time necessary for observation and availability for a child's comprehension which make it look promising for using at outpatient admissions in children of different ages. Key words: amblyopia, color vision, diagnostic methods of color vision

On the sides of a right-angled isosceles triangle, squares external to this triangle are built. The task is to construct a straight line on a plane that divides a figure consisting of these three squares into two equal-sized (that is, equal area) figures. Some parameters determined by this line are calculated, in particular, the areas of parts of the original squares in half-planes. The corresponding results are illustrated by various drawings, tables and graphs.

Full textAbstract:
In this article, a novel and efficient approach based on Lucas polynomials is introduced for solving three-dimensional mixed Volterra–Fredholm integral equations for the two types (3D-MVFIEK2). This method transforms the 3D-MVFIEK2 into a system of linear algebraic equations. The error evaluation for the suggested scheme is discussed. This technique is implemented in four examples to illustrate the efficiency and fulfillment of the approach. Examples of numerical solutions to both linear and nonlinear integral equations were used. The Lucas polynomial method and other approaches were contrasted. A collection of tables and figures is used to present the numerical results. We observe that the exact solution differs from the numerical solution if the exact solution is an exponential or trigonometric function, while the numerical solution is the same when the exact solution is a polynomial. The Maple 18 program produced all of the results.

The proposed method is a development of the well-known one, based on the determination of the sensor's transducers impedance parameters according to the three-element equivalent circuit at two frequencies. The increase in accuracy is achieved due to the step-by-step refinement of parameter values using the values obtained in the previous step using simplified mathematical expressions. Mathematical expressions for calculating the specified parameters are presented. Comparative results of calculations based on known and proposed methods using a computer model are presented, which showed the possibility of significantly reducing the influence of changes in the background electrical conductivity of the solution compared to the known method.

Full textAbstract:
The structure of an electric machine with a rotor, which has three degrees of freedom of rotation (EMTR) and consists of external and internal magnetic circuits, is considered. Between them, in the air gap of a spherical configuration, there is an m-phase rotation winding and a control winding. The excitation of the magnetic field in the EMTR is carried out by means of permanent magnets located on the external magnetic circuit. The scope of application of EMTP in systems of stabilization, observation, tracking, where the rotor performs the function of a gyro-stabilizing element, is outlined. Taking into account the structure of the considered EMTR, the absence of eddy currents in the design and the suitability of the mathematical model of the static magnetic field are substantiated. The calculation of the torque of the EMTR with two- and three-phase rotational windings at different angles of rotor’s inclination relative to the stator axis has been performed. It is shown that the rotation torque of the three-phase winding is 20% higher than that of the two-phase winding. A signifi-cant influence of the control winding on the torque of the three-phase winding and approximately the same influence of the two- and three-phase rotation windings on the processional torque with a significant value of the rotor inclination angle are noted.

The transformation and upgrading of rural hydropower rely on the property right trading market, and the professional property right trading market serves as the foundation to truly transform lucid waters and lush mountains into mountains of gold and silver. The study believes that by using two means, namely, government regulation and market incentive, water resources can be turned into ecological hydropower resources to finally realize the economic value of green energy through the ecological value transforming mechanism. The transforming mechanism, impelled by green hydropower certification and evaluation and professional property right trading market, has realized the ecological values, which not only promotes the green development of the local economy, but also realizes the transformation and upgrading of the rural hydropower industry. With the hydropower property right trading center, the development of the hydropower industry has encountered historic opportunities. At present, it is necessary to strive to improve the corresponding system, mechanism and cultural environment of the trading center to achieve the predetermined goal, and further standardize and improve the transaction activities.

We offer a procedure to guide the Roth IRA versus deductible IRA (RVD) allocation decision. We require users to input 10 values to generate outputs that include contribution and withdrawal tax rates; maximum gain; and, optimal amount to allocate between the two major IRA types. By being at their optimal RVD allocation, we find that a modest earning couple can achieve a lifetime wealth gain amounting to about $180,000 in today’s dollars. We provide figures and tables illustrating RVD outcomes when there are changes in key variables such as salary match, adjusted gross income, portfolio returns, and withdrawal years.

Full textAbstract:
Three-dimensional vibration solutions are presented for rectangular plates with mixed boundary conditions, based on the small strain linear elasticity theory. The analysis is focused on two kinds of rectangular plates, the boundaries of which are partially fixed while the others are free. One of those studied is a rectangular plate with partially fixed boundaries symmetrically arranged around four corners and the other one is a rectangular plate with partially fixed boundaries around one corner only. A global analysis approach is developed. The Ritz method is applied to derive the governing eigenvalue equation by minimizing the energy functional of the plate. The admissible functions for all displacement components are taken as a product of a characteristic boundary function and the triplicate Chebyshev polynomial series defined in the plate domain. The characteristic boundary functions are composed of a product of four components of which each corresponds to one edge of the plate. The R-function method is applied to construct the characteristic boundary function components for the edges with mixed boundary conditions. The convergence and comparison studies demonstrate the accuracy and correctness of the present method. The influence of the length of the fixed boundaries and the plate thickness on frequency parameters of square plates has been studied in detail. Some valuable results are given in the form of tables and figures, which can serve as the benchmark for the further research.

Two schools teach spinal anesthesia, one prefers the lateral decubitus position and the other the sitting position. The vast majority of anesthesiologists worldwide use routinely the hyperbaric solution of bupivacaine for almost all types of surgery, mainly performed in a sitting position. There is renewed interest in understanding spinal anesthesia about puncture position, the various solutions used, and the position of the operating table during the surgical procedure. Understanding the vertebral column, of the anterior and posterior roots, allows the different puncture positions, and the hyperbaric, isobaric, and hypobaric solutions to offer better quality of these techniques and will be shown in this article. The application of the three solutions in different puncture positions, and the position of the surgical table during the procedure, will be shown in seven items in 14 tables, and 6 figures, for the complete understanding of spinal anesthesia. The possibility of performing hemi-spinal anesthesia (unilateral and posterior), and the possibility of performing completely sensory spinal anesthesia without any degree of motor block are discussed. The explanations in this article with the different puncture positions and the three local anesthetic solutions are applied both in the lumbar region and in the thoracic region.

The article presents the results of the research on the age dynamics of higher mental functions among the employees of law enforcement agencies. There was an assumption that the decrease in concentration of attention, visual and somatosensory gnosis and visual memory dominate in the structure of age-related changes in higher mental functions among employees of law enforcement agencies. The sample of the study was 68 soldiers aged from 19 to 41 years (mean age of the group 27 ± 4.78). The methodological complex included methods aimed to evaluate the function of gnosis (Recognition of the figures of Poppelreiter, Had's sampling, Copying of the drawing with a rotation of 180°, Posture transfer, Feeling of Ferster, Reproduction of rhythms), attention (Schulte's Tables, Bourdon's Correction Test) and memory (Memorization of two-valued numbers, the memorization of two semantic series, the test "5 figures"). It was revealed that, irrespective of age, the functional disorder of basal-frontal, "deep" structures and temporal divisions of the brain predominates in the entire sample. The structure of age-related changes is dominated by a decline in visual-spatial functions, changes in visual and somatosensory gnosis, as well as visual memory.

Full textAbstract:
The contrast sensitivity of normal and anomalous trichromats were examined with Landolt-C figures by eye-tracking system. For the measurements, two series of test images (achromatic and colored) were designed. The difficulty levels of the tests were gradually increased after each right answer. In the case of the observation of the ring of the Landolt-C figures, the variables related to fixation duration, fixation count, visit duration and count significantly affected this subject, success or image parameters, and their interactions. The main questions of this study were as follows: Which statistical method is suitable to model the differences between anomalous and normal trichromats? Which eye-movement variables have a significant effect on the investigated parameters and on their interactions? Is there any significant difference between eye-movement variables of normal and anomalous trichromats? How does the survival time of anomalous and normal trichromats change in the case of achromatic and colored figures? The results showed that the right answers of anomalous and normal trichromats can be described with multiple or cross-classified contingency tables evaluated effectively by loglinear regression. The survival analysis showed that normal trichromats are more successful in interpreting colored images, while anomalous trichromats seemed to be more efficient in perceiving achromatic images.

The dependence of Galanin's constant on fuel-plate separation is studied. Galanin's constant arises in the sourcesink method of lattice calculations and normally its value for an isolated fuel plate is used. Our calculations therefore enable the accuracy of that assumption to be assessed. To illustrate the problem, two absorbing and scattering plates, embedded in an infinite moderator and separated by a distance b are considered, with a source in the moderator region. The calculations are carried out via the integral form of the transport equation using the little-known method of Wallace. This approach enables the integral equation to be cast into a particularly useful form for evaluation of the flux and absorption rate in the plates. A variational method and a numerical solution provide results that show that there are significant deviations from the isolated plate approximation. Tables and figures are provided to illustrate these conclusions. In addition to the main result, we take the opportunity to show how Wallace's method can be used to simplify the transport equation for an infinitely reflected slab reactor. We also obtain results for the flux in a half-space in which there is a constant source, using a novel approximation procedure. Comparison with the exact result shows high accuracy.

This study was carried out in order to identify the major viruses infecting pumpkins (Cucurbita pepo)grown in Serbia. Leaf samples from virus-infected pumpkin plants were collected in mid-July 2001. Naked-seeded and hulled oil pumpkins, patty pan, zucchini and summer squash from three different locations were included (Table 1). Virus-infected plants showed different symptoms (Table 2 and Figures 1-4). Due to the great variability of the symptoms, the causal viruses could not be fully and precisely determined by visual examination only. The infected samples were tested by the biotest, as well as by two serological methods, ELISA and EBIA. Polyclonal antibodies raised against cucumber mosaic cucumovirus (CMV), zucchini yellow mosaic potyvirus (ZYMV), watermelon mosaic potyvirus 1 (WMV-1), watermelon mosaic potyvirus 2 (WMV-2) and squash mosaic comovirus (SqMV) were used. In each of the 50 collected samples one or two viruses were detected (Tables 3 and 4). The most prevalent viruses infecting pumpkins were ZYMV (62%) and CMV (58%). WMV-2 was extremely rare.

Full textAbstract:
The properties of the solid magnetic core of the stator of a slotless torque motor with permanent magnets are considered. It is noted that the solid stator under the conditions of low rotation speed has some advantages over the traditional laminated magnetic circuit. These advantages consist in the cost reduction of the design, its compactness and the low time of production preparation. The mathematical model's assumptions and the input data's limitations are formulated. A model of a static magnetic field with a moving electrically conductive medium is chosen. The two-dimensional model is implemented in the "Magnetic fields" interface of the "COMSOL Multiphysics" software. The maximum torque values were obtained and the optimal number of pole pairs was found. The method of calculating the torque based on eddy current losses in the magnetic medium is used. The decrease in torque with increasing rotor speed is calculated.

Full textAbstract:
An analytical solution of the three dimensional advection-diffusion equations has been formulated to simulate the dispersion of pollutants in the planetary boundary layer. The solution is based on the assumption that the concentration distribution of pollutants in the crosswind direction has a Gaussian shape and the wind speed is constant. The analytical solution has been obtained in two cases where, the vertical eddy diffusivity is taken to be dependent on: (a) the downwind distance x only and (b) the vertical height z only. The dry deposition of the diffusing particles on the ground is taken into account throughout the boundary conditions. The resulting analytical formulae have been applied to calculate the concentration of I-131 using data collected from the experiments conducted to collect air samples around the Research Reactor. Statistical measures are utilized in the comparison between the predicted and observed concentrations. The results are discussed and presented in tables and illustrative figures.

Full textAbstract:
Purpose This paper aims to propose a method by merging Legendre wavelets method and quasilinearization technique to tackle with the nonlinearity and to get better and more accurate results. Design/methodology/approach To test the significance of the proposed scheme, the authors applied the method on the model representing magneto-hydrodynamic squeezing flow of a viscous fluid between two parallel infinite disks, where one disk is impermeable and the other is porous with either suction or injection of the fluid. For the sake of comparison, numerical solution by using RK-4 is also computed. From the graphs and tables, it is evident that the proposed method shows an excellent accordance with the numerical solution. Findings The solution converges to the numerical solution when the degree of Legendre polynomials m is increased. For m = 20 in all the three cases, for different values of S, M and A, the graphs of solutions obtained by Legendre wavelet quasilinearization technique show an excellent agreement with numerical solution. Also, it is evident from figures that suction and injection affects the velocity profile in opposite way. For suction, maximum velocity is seen to be at the center of the channel. Magnetic field can be used to regularize the flow and it stabilizes the flow behavior. Originality/value Magnetic field can be used to regularize the flow and it stabilizes the flow behavior.

Full textAbstract:
Introduction: Drawing on the Andersen model, there is a large body of evidence examining the determinants of health care use, such as doctor visits or hospitalization. However, far less is known about the determinants of dental service use, explicitly using the Andersen model. Consequently, the aim of this systematic review is to summarize and critically analyze evidence from observational studies that examine the determinants of dental service use based on the Andersen model. Methods and analysis: The following electronic databases will be searched: PubMed, PsycInfo, and CINAHL. Our main inclusion criterion is: observational studies (cross-sectional and longitudinal) investigating the determinants of dental service use based on the Andersen model. Disease-specific samples will be excluded. Data extraction will concentrate on methods (such as measurement of dental service use), sample characteristics (such as age and gender) and key results. The study quality will be assessed using an appropriate tool. Three steps (selecting the studies, extracting the data and assessment of study conducted) will be performed by two reviewers. The findings will be displayed using figures, summary tables, narrative summaries and meta-analysis (if studies are deemed similar enough and of appropriate quality).

Full textAbstract:
We obtain similarity transformations to reduce a system of partial differential equations representing the unsteady fluid flow and heat transfer in a boundary layer with heat generation/absorption using Lie symmetry algebra. There exist seven Lie symmetries for this system of differential equations having three independent and three dependent variables. We use these Lie symmetries for the reduced-order modeling of the flow equations by constructing invariants corresponding to linear combinations of these Lie point symmetries. This procedure reduces one independent variable of the concerned fluid flow model when applied once. Double reductions are achieved by employing invariants twice that lead to ordinary differential equations with one independent and two dependent variables. Similarity transformations are constructed using these two sets of derived invariants corresponding to linear combinations of the Lie point symmetries. These similarity transformations have not been obtained earlier for this flow model. Moreover, the corresponding reduced systems of ordinary differential equations are different from those which exist in the literature for fluid flow and heat transfer that we have been dealing with. We obtain multiple similarity transformations which lead us to new classes of systems of ordinary differential equations. Accurate numerical solutions of these systems are obtained using the combination of an adaptive fourth-order Runge–Kutta method and shooting procedure. Effects of variation of unsteadiness parameter, Prandtl number and heat generation/absorption on fluid velocity, skin friction, surface temperature and heat flux are studied and presented with the help of tables and figures.

Full textAbstract:
This study investigates the solution of an ocean waste plastic management system model. The model is represented by a nonlinear system which is divided into three compartments: the waste plastic materials W(τ), marine debris M(τ), and the process of recycling R(τ). These compartments form a simulated model that is solved using two collocation techniques based on a shifted version of the Morgan-Voyce (MV) functions, while the first matrix collocation procedure is directly applied to the given model, in the second approach we fuse the technique of quasilinearization together with the shifted MV (SMV) collocation strategy. Moreover, we give the basic reproduction number and discuss the existence of equilibria and the local stability of equilibria are investigated. The basic definitions of the SMV polynomials are introduced and detailed convergence analysis of the related power series expansion in both weighted L2 and L∞ norms are presented. Diverse numerical simulations are performed to prove the accurateness and effectiveness of the presented approaches and the results ate illustrated through tables and figures.

Full textAbstract:
In this paper, we present a novel and unified model for studying the vibration of cylindrical shells based on the three-dimensional (3D) elastic theory and the Carrera Unified Formulation. Our approach represents a significant advancement in the field, as it enables us to accurately predict the vibrational behavior of cylindrical shells under arbitrary boundary conditions. To accomplish this, we expand the axial, circumferential, and radial displacements of the shell using Chebyshev polynomials and Taylor series, thereby reducing the dimensionality of the expansion and ensuring the precision and rigor of our results. In addition, we introduce three groups of artificial boundary surface springs to simulate the general end boundary conditions of the cylindrical shell and coupling springs to strongly couple the two surfaces of the cylindrical shell φ = 0 and φ = 2π to ensure continuity of displacements on these faces. Using the energy function of the entire cylindrical shell model, we obtain the characteristic equation of the system by finding the partial derivatives of the unknown coefficients of displacement in the energy function. By solving this equation, we can directly obtain the vibration characteristics of the cylindrical shell. We demonstrate the convergence, accuracy, and reliability of our approach by comparing our computational results with existing results in the literature and finite element results. Finally, we present simulation results of the frequency features of cylindrical shells with various geometrical and boundary parameters in the form of tables and figures. Overall, we believe that our novel approach has the potential to greatly enhance our understanding of cylindrical shells and pave the way for further advancements in the field of structural engineering. Our comprehensive model and simulation results contribute to the ongoing efforts to develop efficient and reliable techniques for analyzing the vibrational behavior of cylindrical shells.

The struggle for the existence of the biological species is a well-known Prey–Predator model study in the literature. In this study, we present an improved model of Jerri [J. Abdul, Introduction to Integral Equations with Applications, Vol. 10 (Wiley, New York, 1999)] by introducing the intra-species competition term between the same species in addition to the existing environmental changes and few other factors in the model. The demand from the existing (limited) resources and other requirements induces competition between the same species which may alter the survival tactics among themselves. This intra-species term provides strength to the model as it makes the model more realistic. The governing equations are a system of two nonlinear delay integro differential equations, which are solved using spectral collocation method. The role of intra-species coefficients denoting the logistic growth/decay of the two species and two other parameters affecting the population dynamics are analyzed with the three basis functions such as Chebyshev, Legendre and Jacobi polynomials. With the help of simple matrix analysis, the governing equations are converted into a system of nonlinear algebraic equations. Detailed error estimation is computed to compare our results with the existing methods. It is shown with the help of tables and figures that the present method is very efficient, has better accuracy and has least computational cost.

Full textAbstract:
Model-Based Systems Engineering (MBSE) methods have developed a strong foothold in the design space in industry. These methods have proven fruitful when the right method is applied to the right problem. Reliability, Availability, and Maintainability (RAM) is an equally important area. Currently, there is a gap in applying a methodology to integrate the two in the design process, particularly when the design is complex. This work attempts to provide a methodology that results in the successful integration of RAM and MBSE that can be used during the early phases of design. The methodology was developed after an extensive literature review, followed by the illustration of the methodology through an example of a steam turbine fuel system. Each step of the method is applied and explained in the illustrative example, to include figures, tables, and calculations demonstrating the effectiveness of the method, concluding with evidence for validation.

Full textAbstract:
It is known from the scientific literature that magnetic pulse processing of electrically conductive non-magnetic sheet materials helps to reduce residual stresses, especially in welded joints. This is due to magnetoplastic and electroplastic effects. To create such effects in non-magnetic electrically conductive materials with welded joints, an inductor with pulsed magnetic field, U-shaped magnetic circuit and hollow conductor for possibility of active cooling of the winding is proposed. Such inductor allows inducing high-density pulsed currents in electrically conductive non-magnetic sheet materials with welded joints. It studies the parameters of the inductor - active resistance and inductance in the frequency-domain mode. The parameters calculated in two-dimensional and three-dimensional models are compared. The electromagnetic field is calculated using Maxwell equations and finite element method. Parameters of an ends of winding are determined by the difference in the parameters of the three-dimensional and two-dimensional models of the induction system. Resistance is calculated separately in the groove`s part of the winding, the outer part and on the frontal parts. The parameters of the induction system with a ferromagnetic core and non-magnetic thin-sheet alloy AMg6 are calculated for various values of complex amplitude of current in winding. Additionally, the parameters are calculated both without the magnetic core and without the non-magnetic metal. The quantitative comparison of the parameters of the three-dimensional model with the two-dimensional one is performed. The active resistance and inductance of end parts of the inductor are investigated by well-known analytical expressions from handbooks of electric machines. References 11, figures 3, tables 6.

Full textAbstract:
The potential of a partial differential equations model is to anticipate its computational behavior. The simulation of a transient 3D coupled convection–diffusion system using a numerical model is described. The main objective of this article is to offer effective limited contrast compact finite difference techniques for use with nonlinear coupled partial differential systems that mimic overseeing differential frameworks. The three-dimensional compact finite difference formulation serves as the model’s foundation. An analytical model has been used to validate finite difference techniques that are numerically compact. By examining the consistency and union of the arrangement, which may be seen from figures and information tables, we can evaluate the model and the suggested numerical schemes. The schemes are unconditionally stable and accurate up to two orders in time and six orders in space, according to the results of the stability and accuracy tests. The implicit method used in the algorithm’s design was examined for stability criteria. Because mesh-independent solutions for non-linear differential systems are expensive, block tridiagonal matrix structures, measured in terms of L2 and L∞ norms, which are inherent characteristics of schemes and have excellent agreement with the investigation arrangement, are created.

Full textAbstract:
The wear behavior in solid metallic materials is of high importance because of its connection with production cost. In this work, the behavior of wear and wear rate is shown in grinding balls produced from high Fe-Cr-C alloys produced by melting in medium frequency induction furnaces, and molding by automatic fleckless molding machine– Disamatic moldings machine. The total testing time is (12 hrs). The abrasive wear rate, which is the wear resistance multiplied by testing time in mg/Kg.hr. Two grinding balls of each of the three alloys: BC26, BC18, and BC13 are tested by rotating the balls with (50 Kg), cement powder inside a diesel working mixer of circular sections, inclined 45 and rotating by 30 rpm. Weighting and hardness testing results are found in the text, the chemical composition was tested by using spectra analyses type ARL 34000 OE. All the results obtained are shown in the tables and figures in the text. As a result, it can be stated that increasing Cr%, increases hardness, and decreases the wear rate, and the harder and higher the Cr% and C% it contains, the lower the wear rate and the higher wear resistance.

Abstract The aim of this research is to provide bioclimatic design suggestions to improve the thermal comfort of people in hot and humid climates according to the BWh (hot desert climate) Köppen climate classification. The city of Minia is considered one of Egypt’s hot desert regions. This study considered two main variables to achieve thermal comfort according to air velocity and temperature. To select the best bioclimatic design tactic, the findings are reviewed and plotted on the Climate Consultant (CC) Bioclimatic Chart and the Mahoney Table (MT). The proposed procedures are presented as figures relating to the approaches and are examined independently. We conclude that specific bioclimatic design strategies have been applied through the extensive study presented in this paper for Minia City, which can be exported to other regions with comparable climates. These strategies are practically and effectively considered functional architectural approaches that can improve thermal comfort for people. The two tools CC and MT are compared based on 27 recommended strategies that can be achieved according to the bioclimatic parameters that were studied. They agreed with 30% as good natural ventilation, passive solar heating with a high percentage that reached 10% for each. Where there is a difference of 20 recommendations to 70%, this represents other factors or recommendations such as shading with which it is proposed in MT as well as other parameters.

Full textAbstract:
Many solutions about the teleoperation of unmanned robotic excavators have been studied continuously. However, if excavators that are remotely controlled were employed, the probability of an accident would be higher. For this reason, there have been many ways proposed to attempt to reduce accidents in these dangerous situations. In this paper, a novel methodology will be introduced with a focus on the multiple excavators themselves. The proposed method details how one excavator can be generated or expressed as an obstacle in the Configuration-Space (C-space) with respect to another excavator’s side for collision avoidance each other. This method is based on kinematics information which is measurable and given. Therefore, this method can be used or applied independently by using widely used pose sensors and wireless communication devices. The phase of mathematical derivation about obstacle sets is described in detail. The results are shown in accompanying figures and tables for demonstrating that the proposed method detected the proximity and found the collision-free zone accurately. The proposed system can be powerful when applied to a teleoperation system, where it would be particularly useful and helpful to the operator.

BACKGROUND: Speech sound appears first in the child’s speech development and is the primary means of expression. Articulation disorders can hinder the comprehensibility of children’s speech. The speech, in turn, can limit the child’s inclusion in the social and educational environment.
 AIM: To establish frequency and distribution of lambdacism, rhotacism and sigmatism or their combination in preschool children and the frequency and distribution of these articulation disorders among boys and girls.
 MATERIAL AND METHODS: A retrospective analysis of data from preventive examination for early diagnosis of impairments of hearing, speech and sounds in preschool children has been carried out. In the selected sample, only the data for children diagnosed with lambdacism, rhotacism, sigmatism or their combination are analysed. The data is statistically examined, represented in tables and figures and analysed descriptively.
 RESULTS: In the analysed sample, the greater presence of lambdacism was observed before rhotacism and sigmatism. Most commonly, these three types of articulation disorder appear alone, as isolated cases, instead of a combination of two out of the three impairments. They are more common in boys than in girls.
 CONCLUSION: Timely diagnosis and rehabilitation of lambdacism, rhotacism and sigmatism or their combination in preschool children will enable easier and faster integration of the children in the social and educational environment without leaving lasting consequences

Full textAbstract:
A hotel's economic feasibility and progress depend on the efficient use of all resources, along with human resources (HR). Absenteeism is a critical issue that almost all employers encounter daily. It imposes considerable financial burdens on organizations and has a negative impact on productivity and performance. The majority of research has revealed that absenteeism is a multifaceted construct impacted by numerous factors, both personal and organizational. Although researchers have attempted to identify the factors that contribute or are associated to absenteeism in order to devise suitable solutions. The research on the relationship between organizational and personal factors and absenteeism appears to be contradictory. A few studies found no correlation between these two variables, whereas some found a weak to moderate correlation between the two variables. Furthermore, there are few research studies on absenteeism in the Sri Lankan hotel industry. As a result, the current study sought to ascertain whether organizational and personal factors influence absenteeism in selected 3-5 star grade tourist hotels in the Galle District. The 14 three to five-star tourist hotels in Galle District were the study's target population. The sample size was determined using a non-probable random sampling method. As a result, a sample of five three to five star tourist hotels in the Galle District was preferred. A questionnaire was used to collect primary data from respondents for the study. The Statistical Package for Social Sciences (SPSS) was used for analysis, which allowed the researcher to express the data in the form of tables and figures. Previous research has discovered that there are several factors that can influence employee absenteeism. According to the literature review, factors such as promotion satisfaction, coworker support, pay satisfaction, age, gender, tenure, number of dependents, and marital status can all have an impact on absenteeism.

Abstract Background The paper investigates the analytical and numerical solution of the radiation effect on MHD flow of Rivlin–Ericksen nanofluid of grade three through a porous medium with a uniform heat source between two vertical flat plates. The governing equations are solved analytically using multi-step differential transform method (MDTM) and numerically using finite difference method (FDM) and shooting method by designing MATLAB and Mathematica algorithms. The study discovered that the MDTM, FDM, and shooting methods are effective for solving nonlinear differential equations like this one. Results Graphs and tables show the influence of different parameters on velocity and temperature. Figures and tables show the comparisons between current outcomes and previous results that are accessible. Conclusions The present results showed that the analytical and numerical solutions agree well with previously published outcomes.

Full textAbstract:
Acute pancreatitis (AP) is defined as the presence of two of the following findings: (1) upper abdominal pain; (2) serum amylase or lipase greater than three times the upper limit of normal; and/or (3) characteristic findings of AP on abdominal imaging (contrast-enhanced computed tomography, magnetic resonance imaging, or abdominal ultrasonography). This review addresses AP, detailing the subclassification, epidemiology, pathophysiology, etiology, diagnosis and differential diagnosis, treatment, complications, and prognosis. Figures include abdominal imaging of patients with AP, an algorithm depicting pancreatic collections, and an endoscopic image of the gastric portion of the cystogastrostomy. Tables list systemic inflammatory response syndrome; classification of the severity of AP; etiologies of AP, gallstones, biliary sludge, microlithiasis, and crystals; secondary causes of hypertriglyceridemia; common drugs and drug classes associated with AP; conditions mimicking AP; diagnostic criteria for infected necrosis; and prognostic scoring systems for AP. This review contains 3 highly rendered figures, 9 tables, and 182 references.

Full textAbstract:
A factorial design examines the effects of two independent variables on a single, continuous dependent variable. The statistical test employed to analyze the data is a two-way analysis of variance (ANOVA). This test yields three results: a main effect for each of the independent variables and an interaction effect between the two independent variables. This article explains factorial designs and two-way ANOVA with the help of a worked example using hypothetical data in a spreadsheet provided as a supplementary file. The main effects and interaction effects are explained and illustrated using tables and figures. A short discussion provides general notes about the concepts explained in this article, along with brief notes on repeated measures ANOVA and higher order ANOVAs. Many additional examples, with figures and explanations, are provided in the supplementary materials, which the reader is strongly encouraged to view.
