У статті розглянуто програмно-алгоритмічні методи та обчислювальні аспекти виконання операцій перетворення координат точок на площині. Зокрема це процедури: знаходження нових прямокутних координат вектора при повороті його (або системи координат) на деякий кут у площині зображення; перетворення координат вектора з прямокутної системи координат у полярну та навпаки. При цьому координати вектора відповідають координатам деякої точки об’єкта на зображенні. Ця точка може бути елементом контуру об’єкта або його центром мас. Перетворення координат цих точок дозволяють описати поступальний рух центра мас та обертальний рух об’єкта навколо центра мас. Відповідно розглянуті перетворення координат використовуються під час визначення геометричних параметрів цих об’єктів, аналітичного опису параметрів руху об’єктів на основі афінних перетворень, розробки нових методів перетворення, кодування та стиснення зображень на основі інтелектуальних технологій (фрактали, штучні нейронні мережі). Виконання операцій перетворення координат вимагає багатократного виконання операцій множення та обчислення значень трансцендентних функцій (прямі та обернені тригонометричні функції, квадратні корені). Розглянуто та проаналізовано методи обчислення цих функцій: табличні методи; апроксимаційні методи; таблично-алгоритмічні методи; ітераційні методи. Основну увагу приділено таблично-алгоритмічним методам обчислення полярних координат, визначення відстані та лінійних розмірів об’єктів, їх кутового положення на основі функцій квадратного кореня та арктангенса. Також розглянуто ітераційний метод «цифра за цифрою» (метод Cordic) для обчислення афінних перетворень та переходу між прямокутною та полярною системами координат.

Cost Management and Supply Chain Management: Experiences of Vulnerable SMEs during COVID-19
Authors: Pathak Shubham , Swatdikun Trairong , Hao Yaoxian 
Published: December 2023

Small and Medium Enterprises (SMEs) constitute the vital economic fabric of Thailand, catalyzing growth and employment opportunities. However, the advent of disruptive events, exemplified by the COVID-19 pandemic, poses formidable challenges to their sustainable development. Adequate cost management and supply chain management are crucial for these SMEs to sustain themselves through disruptive scenarios. This study aims at exploring, understanding, and analyzing various factors that would impact the reduced vulnerability of SMEs and enhance the sustainability of the Thai economy. The methodology adopted for this research is the qualitative method. The data has been collected through semi-structured interviews and in-depth interviews, and secondary data has been collected through online and printed sources. The data analysis involves content analysis of the themes that are deduced from the extensive literature review. Furthermore, the data has been analyzed with Strength, Weakness, Opportunity, and Threats (SWOT) to analyze the impacts of internal and external factors on the sustainability of the SMEs. The study's findings divulge a spectrum of challenges spanning cost management intricacies, socio-cultural influences, and economic nuances that collectively impede SME progress. The absence of effective governmental policies, regulations, and actual need assessments of society and the economy results in enhanced vulnerabilities for SMEs. Similarly, the risk perceptions of the SMEs were found to be inaccurate, which led to ineffective cost management strategies and supply chain management during the COVID-19 pandemic. These findings cover the existing literature gap. The research paves the way for further micro-level research into the amalgamated impact of cost management and adequate supply chain management, especially during disruptive events such as the COVID-19 pandemic.

The objective of this study is to compare and underscore the advantages and disadvantages of learning English in non-English speaking countries to propose the concept of a new English teaching method for students from non-English speaking countries (the case of Russia, Spain, Serbia, and Indonesia). The study used a mixed-methods approach with qualitative analysis of literature from Russia, Serbia, Spain, and Indonesia, and a research questionnaire was developed. 1595 participants were recruited for a survey determining their experiences of learning English and students’ perspectives on English teaching methods in non-English speaking countries. The data went through thematic analysis in the qualitative part of the research and descriptive analysis in the quantitative survey-based design. Findings of the qualitative analysis revealed both advantages and disadvantages of teaching English to students in selected countries; however, the main findings reported the presence of cultural barriers and students finding it difficult to form meanings from the English language context. Conceptual thinking helped to understand the role of memory and comprehension when learning a foreign language, whereby research focuses on more novel concepts. Future researchers can focus on the area of neural development of students' memory, which can help guide strategies to teach the English language effectively.

Improving Sensitivity of the DEWMA Chart with Exact ARL Solution under the Trend AR(p) Model and Its Applications
Authors: Karoon Kotchaporn , Areepong Yupaporn 
Published: December 2023

The double exponentially weighted moving average (DEWMA) chart is a control chart that is a vital analytical tool for keeping track of the quality of a process, and the sensitivity of the control chart to the process is evaluated using the average run length (ARL). Herein, the aim of this study is to derive the explicit formula of the ARL on the DEWMA chart with the autoregressive with trend model and its residual, which is exponential white noise. This study shows that this proposed method was compared to the ARL derived using the numerical integral equation (NIE) approach, and the explicit ARL formula decreased the computing time. By changing exponential parameters that were relevant to evaluating in various circumstances, the sensitivity of AR(p) with the trend model with the DEWMA chart was investigated. These were compared with the EWMA and CUSUM charts in terms of the ARL, standard deviation run length (SDRL), and median run length (MRL). The results indicate that the DEWMA chart has the highest performance, and when it was small, the DEWMA chart had high sensitivity for detecting processes. Digital currencies are utilized to demonstrate the efficacy of the proposed method; the results are consistent with the simulated data. Doi: 10.28991/ESJ-2023-07-06-03 Full Text: PDF

Published: December 2023

Foreign object damage (FOD) is a common problem in gas turbine engines, particularly in the fan and compressor blades. FOD generally occurs when hard body particles are ingested into an aero-engine fan and compressor blade. High-speed impact on fan titanium alloy blades leads to foreign object damage, which weakens the fatigue performance of the blades. It is important to note that FOD can also cause damage that is not visible to the naked eye, such as internal cracks or fatigue damage. Therefore, regular inspections and maintenance are crucial to detect and prevent FOD damage in gas turbine engines. Also using a microscope for the inspection of blades is important. Proper examination of blades damaged by foreign or domestic object can shed light on blade status and prevent further damage in the future. Here are some of the benefits of using a microscope for blade inspection:
Microscopes can provide high magnification and resolution, allowing for detailed inspection of the blade surface and any defects or damage.
Microscopes can help detect and identify small cracks, chips, or other forms of damage that may not be visible to the naked eye.
Microscopes can provide accurate measurements of the blade's dimensions, which can be important for quality control and maintenance purposes.
Microscopes can help identify the root cause of any damage or wear on the blade, which can inform future design and manufacturing decisions.
Microscopes can provide visual documentation of the blade's condition, which can be useful for tracking changes over time and for communicating with other stakeholders.
Overall, using a microscope for blade inspection can help ensure the safety, reliability, and performance of gas turbine engines and other equipment that relies on blades.
In this study, a comparison was made between visual inspection, borescope control, stereo microscope and SEM-EDX microscope methods used in the detection and removal of foreign material damage. The advantages and disadvantages of these 4 methods are comparatively examined and presented to the attention of the reader.

Published: December 2023

The research examines the influencing factors of low birth weight (LBW) in the work area of ​​the Batakte Public Health Center, Kupang Regency. The specific objective of this study is to identify the risk factors associated with the LBW. In parallel with the research objective, the hypothesis of this study is that there is a relationship among several maternal factors: age, education, number of children, birth spacing, chronic energy deficiency (CED), low hemoglobin in pregnant women, and the practice of antenatal care (ANC) during pregnancy. The sample in this study was some mothers who gave birth in 2020 and 2021, whose data were recorded. The results of the study show that the logistic models of the dominant parameters causing LBW cases are: 1. Pregnant women who experience CED have a risk of giving birth to babies with LBW: 2. The risk opportunities for pregnant women with low hemoglobin (below 11g/dl) is will give birth to a LBW baby: and 3. The risk of pregnant women who never or do not routinely perform ANC is about will give birth to a LBW baby. The results of parameter interpretation show that the dominant factor causing LBW cases in the work area of the Batakte Public Health Center is pregnant women who experience chronic energy deficiency conditions, low hemoglobin, and pregnant women who have never or only once done Antenatal care (ANC) in the work area of the Batakte Public Health Center.

Published: December 2023

Tuberculosis is an infectious disease caused by Mycobacterium Tuberculosis. Tuberculosis patients undergoing long-term tuberculosis treatment have a high risk to get asthma as a second infection. A person suffering from asthma cannot recover. Asthma therapy is only to control the development of asthma so that asthma does not get worse. In this study we discusses the spread of tuberculosis with asthma as a secondary infection. We perform the model into system of non- linear differential equation that consist of six equation because the population divided into six sub-population which are susceptible, infected by tuberculosis, undergoing tuberculosis treatment, infected by asthma, undergoing asthma treatment and recovered from tuberculosis. From the model that has been formed, we perform the analysis to obtain the equilibrium point and the basic reproduction number. Then we show the local stability of the equilibrium point and perform simulations to provide an illustration. From the analytical result, we got that the spread influence by recruitment rate, infection rate, natural death rate, tuberculosis treatment rate and death rate because of tuberculosis.

Transferring credit risk to an insurance company is a way to mitigate risk. Premiums should be calculated accurately to attain economic value for both the lender and the guarantor. The aim of this study was to determine the net single premium (NSP) values for an unsecured credit insurance product using the expected credit loss (ECL) method from IFRS 9. This study used data generated through simulation of insurance policies issued in 2015 or 2016. Their state classifications were monthly observed from 2016 to 2020. The probability of disbursed claim (PDC) parameter replaced the probability of default parameter on the ECL model, whereas the PDC model was constructed based on the components of a state-transition probability matrix, obtained with the Markov chain approach using the cohort method: = 0.999181, = 0.000130, and = 0.000689. The PDC model validation showed relatively decent results, whereas MSE = 2.457% and zs = 0.608 with a = 5%. These results indicated that the PDC model was a good fit to calculate ECL. 5,000 iterations were done as part of the cash flow simulation process, whereas debtors’ loan amounts were randomly generated during each iteration, and the average NPV of these iterations was -Rp564.419.305. Based on model sensitivity analysis, cash flow values were most sensitive to the variable used to construct the PDC model (). Thus, the 5,000-iteration process was repeated with the newly adjusted PDC value, which were = 0.998924 and = 0.000946. The new average NPV of these iterations was Rp409,877,840, indicating that the constructed ECL model was a good fit to calculate NSP values for unsecured credit insurance products.
AN ORDER-P TENSOR MULTIPLICATION WITH CIRCULANT STRUCTURE
Authors: Mangngiri Itsar , A’yun Qonita Qurrota , Wasono Wasono 
Published: December 2023

Research on mathematical operations involving multidimensional arrays or tensors has increased along with the growing applications involving multidimensional data analysis. The -product of order- tensor is one of tensor multiplications. The -product is defined using two operations that transform the multiplication of two tensors into the multiplication of two block matrices, then the result is a block matrix which is further transformed back into a tensor. The composition of both operations used in the definition of -product can transform a tensor into a block circulant matrix. This research discusses the -product of tensors based on their circulant structure. First, we present a theorem of the -product of tensors involving circulant matrices. Second, we use the definition of identity, transpose, and inverse tensors under -product operation and investigate their relationship with circulant matrices. Third, we manifest the computation of the -product involving circulant matrices. The results of the discussion show that the -product of tensors fundamentally involves circulant matrix multiplication, which means that the operation at its core relies on multiplying circulant matrices. This implies the -product operation of tensors having properties analogous to standard matrix multiplication. Furthermore, since the -product of tensors fundamentally involves circulant matrix multiplication, its computation can be simplified by diagonalizing the circulant matrix first using the discrete Fourier transform matrix. Finally, based on the obtained results, an algorithm is constructed in MATLAB to calculate the -product.
