A chest X-ray can convey a lot about a patient's condition. However, it requires a specialized and skilled doctor to determine the type of lung disease with high accuracy. Here comes the role of deep learning techniques (DL) and artificial intelligence (AI) in accelerating the process of detecting lung diseases and classifying them with high precision, which saves time and effort for the patient and the doctor alike. This work presents a proposed model for a machine learning (ML) and AI system to analyze chest X-ray images and categorize them into four cases normal, viral pneumonia, bacterial pneumonia, and coronavirus disease 2019 (COVID-19). The system relies on extracting Mel frequency cepstral coefficient (MFCC) features from a dataset consisting of 4,800 chest X-ray images, and then these features are used to train four basic classifiers based on the data mining tool Orange3, which are adaptive boosting (AdaBoost), decision trees (DTs), gradient boosting (GB), and random forest (RF). The model was tested and evaluated, where the AdaBoost classifier excelled with an accuracy of 100%, followed by RF with an accuracy of 99.5%. Finally, GB and DTs came with a classification accuracy of 98.5%, and 97.2%, respectively. [ABSTRACT FROM AUTHOR]

Burmese language is challenging for speech emotion classification. Moreover, it is lack of resource and few research was made in this topic. To solve the challenging problem, novel feature extraction for Burmese language is proposed. For lack of resource, Burmese speech emotion corpus called BMISEC is built. To support the challenging problem, the advantages of feature extractions are fused to create a robust feature. Four features are fused. Novel text-tone feature, local binary pattern, mel-frequency cepstral coefficient and discrete wavelet transform are fused. To progress the performance, deep learning method called DenseNet-Emotion is used for classification. Support vector machine is used in DenseNet's classifier layer. To show the robustness of the proposed system, three types of experiments are made on Tensorflow framework. They are ablation study, experiments with three publicly available datasets and experiments with the previous research methods and they are compared with the proposed method. It is found that feature fusion is superior to only one feature in emotion recognition. BMISEC gets better performance than other datasets. Moreover, the proposed method gets the superior result than previous research methods. The proposed method gets the accuracy of 88.388% for 50 epochs. [ABSTRACT FROM AUTHOR]

The coil is used for electrical connection and energy conversion in the electromagnetic pulse welding (EMPW) process, so its structure affects the welding effect. In this work, for the dual H-shaped (DH) coil, the influence of the symmetry coefficient on the Cu-Al sheets EMPW was studied through the simulation and experiment. When the voltage was 7 kV and the symmetry coefficient g was 0.75, 1, and 1.33, the Vc-β trajectory curve contained by the simulation combined with the welding window curve (WWC) to analyze the dynamic process and welding effect. The relative impact speed was the fastest and the corresponding weld seam length was the longest when g was 1.33. The welding experiment results were consisted with the simulation results, it was beneficial to weld the Cu-Al sheets when g was 133. The symmetry coefficient could change the impact speed and angle to affect the welding effect. This work is of great significance for DH coil design. [ABSTRACT FROM AUTHOR]

Hospitality professionals with insufficient food safety knowledge (FSK) poses a major risk to food safety in their respective organisations. This study aims to investigate the level of food safety knowledge of hospitality professionals, as well as the attributes influencing food safety knowledge and their corresponding relationships. A total of 862 hospitality professionals working in hotels, restaurants, cafes, universities and colleges located in two different cities in India participated in a cross-sectional study between July 2022 and August 2022. A self-administered questionnaire consisting of 20 items related to food safety knowledge was used to collect the data. Both descriptive (frequency distribution, central tendency, norms) and inferential statistics (Pearson correlation coefficient) were conducted in this study to investigate the level of food safety knowledge and measure the association between food safety and educational qualification, age, experience and adoption of training related to food safety. The findings of this study contribute to the current literature about mitigating food-borne illnesses through creating a level of knowledge with proper education, experience and training among hospitality professionals.

The recovery of heat and water from low-grade flue gas is of considerable importance for energy conservation and environmental preservation. While the full-open absorption heat pump shows promise as a means of achieving heat and water recovery, the lack of research on heat and mass transfer performance of open-type solution evaporation regeneration represents a significant impediment to its design and operation. This paper experimentally investigates the regeneration performance of an open-type spaying tower equipped with ceramic structured packings. Two different regeneration modes are proposed, namely ambient air receiver mode and flue gas receiver mode, to utilize air or low-grade flue gas as a driving source. The impact of different input parameters on the regeneration characteristics, including heat transfer capacity, water removal rate, thermal efficiency, and humidity effectiveness, are demonstrated. The findings indicate that the enhancement of regeneration can be achieved through the increase of solution flow rate, solution temperature, and flue gas flow rate in both regeneration modes. However, high solution concentration and flue gas humidity ratio can weaken water removal rates and reduce thermal efficiency. For the regeneration of CaCl2-H2O with a concentration of 55%, flue gas around 200°C with a humidity ratio below 44 g/kg can successfully drive the solution regeneration process. When the solution concentration or flue gas humidity ratio continues to rise, additional energy is necessary for regeneration. Furthermore, the coupled heat and mass transfer coefficients are fitted, which can contribute to the design and optimization of the open-type regenerator. [ABSTRACT FROM AUTHOR]

In this paper, we explore the coefficient signs in weighted logistic regression, a variation of logistic regression that includes positive weights and is commonly used for handling uneven data sets and reject inference in credit scoring. Initially, we examine simple weighted logistic regression. Assuming full rank and overlap, we demonstrate that the slope's sign matches the sign of the difference in weighted averages of the independent variable across two groups, 1 and 0. We extend this analysis to multiple weighted logistic regression by employing two vectors: one representing the slopes and the other the differences in weighted averages of the independent variables across the groups. We establish that if one vector is zero, the other must also be zero. Additionally, we prove that if the slope vector isn't zero, the angle between these vectors will be acute. Our theoretical results can serve as a preliminary step prior to feature selection, which is important in logistic regression. Our numerical analysis further illustrates how our theoretical results can be applied to the well-known German Credit Data for reject inference. Additionally, we provide a detailed explanation of feature selection in our analysis.

Link slabs have been widely used to reduce the number of expansion joints. However, traditional reinforced concrete link slabs are prone to cracking issues, making it crucial to accurately calculate their internal forces. Currently, the most advanced link slab analysis methods treat the link slab and adjacent span as a rotational spring to simulate their restriction on the girder end rotation. However, this method does not comprehensively consider the link slab's influence, leading to conservative results. To address this issue, this study further considers the influence of girder end deformations on adjacent span, resulting in more accurate calculations of the link slab's internal forces. Additionally, the concept of the girder end rotation reduction coefficient is put forward for the first time, which provides a clearer and more quantified understanding of the link slab's influence. The proposed method is verified by a model test and a site test, which shows a significant improvement in accuracy compared to existing analytical methods. On this basis, a parametric study is conducted to investigate the influence of various parameters on the girder end rotation reduction coefficient, which indicates that span length, girder spacing, and support configuration have the greatest influence.

The treatment of industrial wastewater by economical and efficient methods is being explored to improve treatment efficiency and costs. Wastewater treatment via biological methods to reduce carbonaceous matter is common in the form of an activated sludge process (ASP). In the current work, the aerobic decomposition of waste was carried out in a reactor with constant stirring with a Rushton type turbine. The optimum values of the flow rate of air were obtained for two reactor impeller configurations for better waste degradation. The extent of degradation in the stirred tank reactor was studied for different values of impeller clearances. Two configurations, C1 and C2, were investigated. It was observed that under a continuous air supply for 36 hours, the impeller configuration C2 provided 80% degradation compared to 74.4 % for C1. Increased values of superficial gas velocity (UG) and impeller speed resulted in decreased degradation due to shear stress on microorganisms for two impeller configurations. The hydrodynamic study confirmed that the impeller configuration C1 required less power consumption than C2 for the same operating condition. The k-epsilon turbulent model and the population balance model were used in combination. The models were validated with the experimental results of the hydrodynamic parameters for the values of operating parameters over a considerable range. The forecasting of mass transfer coefficients from different models was compared with practically determined values for the two configurations of impeller positions in the tank.

At present production of high-yielding varieties of common beans in Russia with a high adaptive potential will stabilize and even increase the production of leguminous products in various geographical areas with varying degrees of moisture and heat supply. At the same time, an important condition for common bean varieties is that they must have a high degree of ecological plasticity and individual characteristics to changes in environmental factors.The field experiment was carried out on the basis of the FSBSI «PAFSC RAS» in the period from 2015 to 2017. The soil of the experimental plot is represented by a light chestnut solonetsous soil type.Evaluation of the reaction of 10 varieties of common beans of the studied leguminous crop from the collection of VIR named after V.I. N.I. Vavilov to a sharp climatic changes, e. g. sharp summer temperatures and dry winds during cultivation, will allow us to resolve issues with the selection of varieties for each peasant farm or a private household plot.The purpose of the research was to analyze the adaptability of common bean varieties, as well as to evaluate the protein content in the grain.To analyze the productivity and adaptability of common bean varieties in terms of varying their yield, the concept of “average varietal yield” was used, adopted by L. A. Zhivotkov, the author of the methodology.In the course of the analysis it was found that the maximum indicators when calculating the coefficient of adaptability were obtained in such varieties as Ballada – 1,06, Stanichnaya – 1,09, Oka – 1,15, Nerussa – 1,50, Gornal – 1,68. At the same time, the yield of these varieties in different years of research exceeded 3,0…4,0 t/ha. These varieties exceeded indicator 1 (adaptability coefficient), which indicates a high adaptive ability.The results of scientific research on the selection of high-yielding varieties with high adaptive capacity indicate the prospects for the cultivation of leguminous crops in the Astrakhan region.

We prove a conjecture concerning the third Hankel determinant, proposed by Kumar and Kamaljeet in [A cardioid domain and starlike functions, Anal. Math. Phys. 11 (2021), Art. 54], which states that |H3(1)| ≤ 1/9 is sharp for the class S ℘ * = { z f ′ (z) / f (z) ≺ φ (z) : = 1 + z e z } . In addition, we also establish bounds for sixth and seventh coefficient, and |H4(1)| for functions in S ℘ * . The general bounds for two and three folds symmteric functions related with the Ma-Minda classes S * (φ) of starlike functions are also obtained. [ABSTRACT FROM AUTHOR]

This article analyzes patterns of potassium sorption from an aqueous solution of KCl by three types of soils (lowland peaty, light chestnut, and alluvial soddy types) formed under conditions of Western Transbaikalia and by their treated analogs. Potassium sorption in soil is measured in laboratory conditions based on an experiment in which soils are balanced using a solution with different initial concentrations of KCl (0.5, 1.0, 3.0, and 5.0 mmol/L) for 24 h. The resulting potassium sorption isotherms are described by the Langmuir and Freundlich equations. Parameters of these equations indicate an inhomogeneity of the bonds of potassium ions with the solid phase of soils. The maximum potassium uptake by the studied soils varies from 53.2 to 87.8% at the initial KCl concentration of 1 mmol/L, while the coefficient of distribution (Kd) of potassium between the solid and liquid phases of the soils used in the study varies from 11.37 to 72.11 L/kg. The highest Kd value has been determined for the lowland peaty soil and the lowest value for the alluvial soddy soil. The patterns of changes in Kd of potassium are correlated with the degree of its absorption by the soil. The maximum sorption capacity of potassium by the soils varies from 54.05 to 98.04 mmol/kg in the upper humus horizons and from 35.71 to 100.0 mmol/kg in the lower horizons. The values of the KL coefficient of the Langmuir equation are slightly lower in humus horizons (0.272‒0.668 L/mmol) than in mineral horizons (0.102–1.511 L/mmol), which indicates that potassium binds more strongly in mineral horizons. The KF coefficient of the Freundlich equation varies from 9.98 to 23.51 mmol/kg in humus horizons and from 6.63 to 26.77 mmol/kg in mineral horizons. It has been established that the studied soils are characterized by different sorption activities with respect to potassium and form the following decreasing series with respect to the level of potassium absorption: lowland peaty > light chestnut > alluvial soddy soils.

There are several general concepts that allow obtaining explicit formulas for the coefficients of generating functions in one variable by using their powers. One such concept is the application of compositae of generating functions. In previous studies, we have introduced a generalization for the compositae of multivariate generating functions and have defined basic operations on the compositae of bivariate generating functions. The use of these operations helps to obtain explicit formulas for compositae and coefficients of generating functions in two variables. In this paper, we expand these operations on compositae to the case of generating functions in three variables. In addition, we describe a way of applying compositae to obtain coefficients of rational generating functions in several variables. To confirm the effectiveness of using the proposed method, we present detailed examples of its application in obtaining explicit formulas for the coefficients of a generating function related to the Aztec diamond and a generating function related to the permutations with cycles.

In this paper, the reconstruction of a differential operator from incomplete spectral characteristics is concerned. We prove that coefficients of a second-order differential equation with the eigen-parameter appearing at the right-end boundary condition can be uniquely determined from incomplete nodal data. The new results in this paper are unlike to the known results for the classical Sturm-Liouville operator in [21]. [ABSTRACT FROM AUTHOR]

The study is devoted to the determination of the coefficients of the degree of contact of rolling surfaces, considering the tolerance field of rolling bodies, as well as the influence of the coefficients of the degree of contact on the maximum contact stresses in ball radial bearings. A method has been developed for determining the maximum value of the coefficient of the degree of contact of rolling surfaces of ball radial bearings, taking into account the tolerance field of rolling bodies. It is established that the coefficient of the degree of contact of the rolling surfaces for each bearing size with a certain radius of the raceways is located in a range that depends on the limiting dimensions of the rolling elements. It is shown that the coefficient of the degree of contact of the rolling elements with the tracks of the outer ring, with the same auxiliary value, considering the sum and difference of the curvatures of the rolling surfaces, is greater than the inner one. Therefore, in order to reduce contact stresses on the outer ring of the bearing, the radius of its raceway can be made smaller than the inner one. A method has been developed for calculating the maximum contact stresses on the raceways of radial ball bearings, taking into account the coefficient of the degree of contact of rolling surfaces and the tolerance field of rolling bodies, which allows calculating contact stresses for radial ball bearings of any size at any coefficients of the degree of contact of rolling surfaces.

It is believed that one of the main conditions for the absence of a shortage and stability of food prices on the domestic market is a sufficient level of food self-sufficiency, calculated as the ratio of the volume of production of this type of food to the volume of its use in the territory of the given country. However, this approach has a weak point: production volumes in the numerator are agricultural raw materials, and not consumer-ready industrial products. Considering the export channel of the extraction of food raw materials, the production volumes of agricultural goods sufficient for food self-supply do not guarantee their availability at national enterprises of the food industry to produce semifinished foods and ready-made food in a quantity sufficient for the food market to function without a deficit. Therefore, the purpose of this study is to test the hypothesis that the violation of industry proportions of agri-food production is one of the reasons for the growth of the consumer price index in the food market of Ukraine. The authors of this study proposed the “coefficient of the ratio of gross value added created in the food industry to gross value added created in agriculture” as an indicator that describes the sectoral structure of agri-food production. It was found that, provided the other factors of influence remain unchanged, an increase in the coefficient “the ratio of gross value added created in the food industry to gross value added created in agriculture” by 1% leads to a decrease in the consumer price index of food products and soft drinks by 0.317%. It was concluded that to ensure the stability of national food prices, such a coefficient should not be less than 1. The prospects of further research include the development of an organisational and economic mechanism for the development of a closed value chain in the system of national agri-food production

Pressure intensifiers have their utilization in hydraulic circuits, when there is a need for pressure multiplication for some period of time. Using intensifiers provides energy savings, cost reductions or smaller dimensioning. This article is about a pressure intensifier based on rotary flow dividers. Its functioning is evaluated by its pressure-multiplying efficiency. This efficiency is always calculated from values gained from measurements. However, it would be very convenient to be able to evaluate these types of intensifiers without a need to provide specific measurements for every type of intensifier and rather calculate their efficiency using the general parameters of a hydraulic circuit. Therefore, this article is about the description of a model which calculates the pressure-multiplying efficiency only with two input values: the pressure and the speed of an intensifier. Final derived formulas are also used for the efficiency prediction at pressure levels never measured before and then verified by measurements. [ABSTRACT FROM AUTHOR]

In this research, the effect of ultrasound time and dryer type (hot -air and infrared) on the drying time, effective moisture diffusivity coefficient and rehydration of wheat sprouts were investigated and drying kinetics were modeled. To apply ultrasound pre - treatment, the sprouts were placed inside the ultrasonic bath machine for 0, 5, 10, and 15 minutes, and after leaving the machine and removing extra moisture, the samples in thin layers were placed in the hot -air (with a temperature of 70°C) and infrared (power of 250 W) dryers. The results showed that sonication up to 5 minutes, causes an increase in moisture removal rate from the sprouts, an increase in the effective moisture diffusivity coefficient, and as a result, reduces the drying time. By increasing sonication time from zero to 5 min, the average drying time of sprouts in the hot -air and infrared dryers decreased from 126.7 min to 120.0 min, and from 25.7 min to 21.3 min, respectively. The average drying time of the samples in the hot -air dryer was 150.8 min and in the infrared dryer was 28.0 min. Also, the average effective moisture diffusivity coefficient calculated for the samples placed in the hot - air dryer was equal to 1.65×10 -10 m²S-1 and for the infrared dryer it was equal to 8.59×10-10m² s-1 . The time of ultrasound and drying treatment had significant effects on the rehydration of samples, and the value of this parameter was higher for samples dried in the hot -air dryer. In order to investigate the drying kinetics of wheat sprouts, mathematical models were fitted to the experimental data, and the Page model with two parameters (k and n) was chosen as the best model based on the highest accuracy. Generally, 5 minutes pre -treatment by ultrasound and then using an infrared dryer is the best condition for drying wheat sprouts. [ABSTRACT FROM AUTHOR]

Introduction: Due to the high radiation dose used in radiotherapy, the human tissue is usually replaced with tissue substitutes in order to develop new treatment techniques. Tissue substitutes have not been reported for colorectal cancer tissue (CRC). This study aims at developing tissue substitutes for the CRC tissue with respect to the mass attenuation (µm) and mass energy absorption coefficients (µen/ρ) within the energy range of 6 - 15MV. Material and Methods: Colorectal cancer tissue and four locally sourced materials namely beeswax, gelatine, rice powder, clay, and their mixtures - Clarice, gelarice, gelaclay, and bewaclay were subjected to Rutherford Backscattering Spectrometry (RBS) to determine their elemental composition. Results from the RBS were used in XCOM, a web-based photon interaction software designed by the National Institute of Standards and Technology, USA to determine their theoretical µm and µen/ρ values. Again, these materials were exposed to a narrow beam of x-rays at energies of 6 and 15MV to obtain their experimental µm and µen/ρ values. Results: Revealed that the ratio of CRC tissue to the test materials ranged from 0.946 (beeswax) to 1.07 (clay) for both theoretical and experimental values with bewaclay having a ratio of 1.01 compared with 1.00 for CRC and a p = 0.541 and p = 0.663 with respect to µm and µen/ρ respectively. Conclusion: Bewaclay with the closest match can be used as a tissue substitute for the CRC tissue between 6 - 9MV with respect to µm and µen/ρ as parameters for matching. [ABSTRACT FROM AUTHOR]

The paper touches upon a newly developed methodology for determining the automobile physical wear coefficient, taking into account some technological factors during operation that compose the rolling stock life cycle in the given operating conditions. A concept for determining the operation period of an automobile has been proposed based on maintaining the smooth operation of the rolling stock throughout the life cycle. The quantitative and qualitative indicators of automobile physical wear are determined aimed at solving the problem. The theoretical and scientific experimental research has identified the analytical connections of their interactions and relations. Given the stochastic nature of physical wear coefficient variations, it has been considered as a random value, and the characteristics of its variations pattern have been determined.

The objective of the present study was to examine the relationship between maximal effort force production and anthropometric measures of upper-arm volume. Thirty healthy young participants (15 women) performed 5 isokinetic concentric and eccentric maximal effort elbow flexor/extensor contractions on separate days. Measures of arm length, circumference, and skinfold/subcutaneous fat thickness were used to obtain a measure of arm volume, modeled as 2 separate right-angle frustra. Single-variable regression analyses demonstrated significant (P < .001) second-order polynomial relationships between maximal effort elbow flexor and extensor force with arm volume (r²= .63-.86). The major findings demonstrated that strong and positive relations between maximal force production and estimates of limb volume can be observed using nonlinear modeling and a closer [ABSTRACT FROM AUTHOR]

The most basic rule for the management of patients in the emergency departments (EDs) and critical & intensive units (ICUs) are quick decision and quick order medication. For this reason, calculator applications are a necessary part of EDs in order to calculate some drug doses quickly. With the simple formula we discovered, it will be much easier to place an order for the 4 most frequently used drugs of the EDs (dopamine, dobutamine, norepinephrine, epinephrine). We recommend this simple and fast calculation method to all EDs and ICUs with fast inotrope bag (FiB) coefficient. This coefficient has been developed especially for simple pump devices or dosing devices that do not use ready-made inotropic drug bags and that, if needed, first control the preparation of the solution and then the hourly infusion of the prepared solution. These devices are used only because the amount of solution to be given to the patient per hour can be monitored. Taking advantage of this coefficient, the inotrope needed by the patient can be administered easily and quickly with only the patient's weight information, and the initial dose corresponds to the dose range recommended by the guidelines for inotropes.
