Published: January 2023

This paper investigates the physico-mechanical and petrographic attributes of the Palaeocene Lockhart Limestone, which were measured, sampled and described from the Rumli and Shah Allah Ditta sections of Islamabad, Pakistan. Petrographic analysis shows that the limestone is categorised mainly into mudstone and wackestone microfacies and the dominant presence of the micrite matrix favours the strength of the rock, whereas veins, microfractures and porosities adversely affect the stability of the rock. Unconfined compressive strength (UCS) and point load test (PLT) analyses show that the limestone samples that have the lowest porosities partnered with bioclasts present the highest UCS and PLT values, and the higher porosities partnered with bioclasts correspond to the lowest values of UCS and PLT. The physico-mechanical analyses reveal that the limestone aggregates are within the limits of the respective standards for utilisation in wearing, coating and cement concrete. The limestone of both sections can be utilised for geotechnical purposes such as crushed material and aggregate sources. Simple regression analysis was employed, and based on these correlations, the limestone of the studied formation is designated as moderately strong and recommended for road or bridge construction.

Authors: Umar M , Noorbhai M
Published: January 2023

BACKGROUND: The minimal standard terminology (MST) was developed by the World Endoscopy Organization (WEO) to standardise endoscopic reporting. This study compared current reporting within the Durban Metropolitan complex with the MST METHODS: This observational retrospective study included 130 upper gastrointestinal endoscopy reports from five different hospitals. The data were compared to the current reporting standard in the MST. The Noorbhai Maharaj (NM) score was used to assess and grade the quality of reporting RESULTS: Each of the five hospitals has different endoscopic reporting systems. One hundred and thirty patients were included in the study, of which 60 were female. The indications for upper endoscopy were stated in 77 reports (59%). The commonest indications were epigastric pain (23%), dyspepsia (10%) and heartburn (10%). Sedation information per hospital was mostly seen at Inkosi Albert Luthuli Central Hospital (IALCH) (83%), followed by Prince Mshiyeni Memorial Hospital (PMMH) (67%), Addington (ADH) (13%), King Edward VIII Hospital (KEH) (13%), and RK Khan Hospital (RKKH) (0%). Consultant endoscopies per hospital were RKKH (91%), IALCH (86%), PMMH (78%), ADH (73%) and KEH (40%). All 130 reports were graded as NM Grade C. Scores of less than 20 points were seen in 106 reports (82%) and reflected across the different hospitals as follows: RKKH (100%), ADH (97%), KEH (93%), PMMH (56%) and IALCH (55% CONCLUSION: There is no uniform structured endoscopic reporting system within the Durban Metropolitan Hospital complex. The current reporting methods do not meet the MST. The introduction of a structured standard endoscopic reporting system could improve the quality of reporting

Published: January 2023

Electricity is a very important concept in learning Physics. Mastering this concept can make learning Physics meaningful and relatable to real life problems. However, literature indicates that students have poor conceptual understanding of concepts about electricity. The current research aims to improve Form 5 (aged 17 years) students’ understanding of direct current circuits by using Concept Cartoons Worksheets. Concept Cartoons are A single-group pre-test/post-test investigation was carried out using seven Concept Cartoons Worksheets designed to address common conceptual misconceptions about direct current circuits with a total of 30 physics student participants. The seven Concept Cartoons were modified based on the Concept Inventory Test “Determining and Interpreting Resistive Electric Circuit Concepts Test (DIRECT). Concept Cartoons Worksheets were used to correct students’ misconceptions about direct current circuits and to increase their level of conceptual understanding. The data collected were analysed quantitatively to obtain percentages, means, and t-test values. The descriptive statistics showed an increase in the level of student’s conceptual understanding after the use of Concept Cartoons. The t-test analysis reported that the difference was significant. The results show that Malaysian students do have misconceptions about electricity concepts. However, Concept Cartoons Worksheets are effective to overcome students’ misconceptions about electrical concepts, specifically toward current circuits. Concept Cartoons are not only effective in overcoming misconceptions among students, they are also refreshing and unique because of the cartoons presented while relating to Physics concepts that are abstract.
Self-Confidence as the Predictor of Metacognitive Awareness in High School Students
Authors: BOZGÜN Kayhan , AKIN KÖSTERELİOĞLU Meltem
Published: January 2023

Metacognitive awareness is said to be reflected by self-confidence scores, and there exists a mutual relationship between them. This study was conducted to examine the role of self-confidence in predicting metacognitive awareness in high school students and to examine whether gender, grade point average, type of high school and father’s education level played a role in this relationship. The data were obtained from 390 high school students studying at two different types of high school (general and vocational) using two different scales. Research data were analyzed through hierarchical regression analysis method to determine the predictiveness. Results showed (i) the metacognitive awareness scores were moderately and highly correlated with the self-confidence level total score and sub-dimension scores; (ii) participants’ self-confidence scores explained 46% of the change in metacognitive awareness scores; (iii) the type of high school and grade point average had 9% effect on metacognitive awareness scores. It is recommended to examine the relationships of metacognitive awareness and self-confidence with different variables and to conduct experimental studies. The co-development of metacognitive awareness and self-confidence in students should be emphasized by families and educators. It is thought that the current study will be useful in relation to its results for understanding the importance of self-confidence and metacognitive awareness of high school and of those at other levels.

Due to the widespread use of the Internet, digital space has now pervaded schools. This study aimed to investigate student-teachers’ perspectives and experiences of digital citizenship through project-based learning in a teacher institution in Indonesia. A case study research design was employed using content analysis to analyze the data from semi-structured interviews, observation, and daily journal report. The results showed that technology overuse requires moral guidance in terms of digital citizenship. The student-teachers viewed that digital citizenship provides some principles that encompass knowledge, skills, and appropriate behavior to use technology safely and responsibly. They asserted that digital citizenship is a necessary skill for prospective teachers, particularly considering the growing demand for schools to develop character education programs that address the topic of student technology use. After engaging in digital-issue-driven project-based learning, the student-teachers opined that project-based learning will be beneficial to learners’ autonomy engagement in constructing an understanding of the digital world. Project-based learning also provides opportunities for learners to advance and grow digital skills that are relevant to the 21st century within a real-world context. This study has implications for educators, school principals, and policymakers in ensuring that youths access curricula at all grade levels for them to be able to show appropriate and responsible behavior in both online and offline environments.

Published: January 2023

Son yüzyılda, polilaktik asit (PLA), akrilonitril bütadien stiren (ABS) ve polietilen tereftalat glikol (PET-G) gibi polimer malzemeler hafif, ucuz, sürdürülebilir olması ve mühendislik uygulamaları için yeterli dayanımı sağladıklarından dolayı bir çok endüstriyel alanda sıklıkla kullanılmaktadır. Plastik malzemeler çoğunlukla ekstrüzyon metoduyla üretilse de, üç boyutlu (3B) baskı yöntemi de geleneksel imalat yöntemlerine göre avantajlarından dolayı son on yılda araştırmacıların dikkatini çekmektedir. 3B baskı ile üretilen polimerlerle ilgili literatürdeki çalışmalar incelendiğinde, çalışmaların çoğunlukla çekme, basma, üç nokta eğme gibi mekanik performansı belirleyici testler üzerine odaklandığı görülmektedir. Bu çalışmada ise, eriyik yığma modelleme (EYM) metoduyla üretilen PET-G parçaların sertlik ve çekme dayanımlarının belirlenmesinin yanı sıra, parçaların 20 ⁰C, 40 ⁰C ve 60 ⁰C gibi farklı ortam sıcaklıklarındaki ağırlık düşürme darbe yanıtına, katman yüksekliğinin (0,1 mm, 0,2 mm ve 0,4 mm) etkisi araştırılmıştır. Sonuçlar göstermektedir ki, katman yüksekliği 0,4 mm olan parçada maksimum ortalama sertlik değeri 69,4 Shore D olarak elde edilirken, minimum ortalama çekme dayanım değeri ise 39.24 MPa olarak aynı parçada gözlemlenmiştir. Ayrıca, enerji emmede katman yüksekliğinin test sıcaklığından daha baskın olduğu belirlenmiştir. Sonuç olarak, 60 ⁰C ortam sıcaklığında test edilen 0,1 mm katman yüksekliğindeki numunede maksimum emilen enerji 67.335 J olarak gözlemlenmiştir. Öte yandan, 0,4 mm katman yüksekliğine sahip ve 40 ⁰C ortam sıcaklığında test edilen numune, 28.070 J ile minimum enerji emmiştir. Son olarak makroskopik ve mikroskobik tespitlere göre 0,4 mm katman yüksekliğine sahip numunelerde herhangi bir çatlak gözlemlenmezken, katman yüksekliği 0,1 mm ve 0,2 mm olan numunelerde ise merkezden köşelere doğru uzanan çatlakların oluştuğu tespit edilmiştir.

Bu çalışmada, yüksek müşteri talebi değişkenliği ile karşı karşıya olan bir zincir marketin gerçek hayat sevkiyat problemine odaklanılmıştır. Firma, mağazalarını bulundukları bölgelere göre gruplandırmış ve her mağaza grubunun ikmali için bir dağıtım merkezi (DM) oluşturmuştur. Düzenli aralıklarla bu DM’lerden kendine bağlı olan mağazalara ikmal yapılmaktadır. Mevcut durumda firma, mağazalardan gelen yüksek talep değişkenliğine cevap verebilmek için çok yüksek sözleşme maliyetleri pahasına DM’lerdeki işçi sayısını artırıp azaltmaktadır. Buna rağmen mağazaların talepleri zamanında karşılanamamakta ve satış kaybı yaşanmaktadır. Bu çalışmada, değişkenliğin getirdiği bu olumsuz etkileri minimize etmek üzere DM’ler için sevkiyat planı oluşturulması problemi ele alınmıştır. Önce problemin doğrusal programlama modeli geliştirilmiştir. Büyük boyutlu örnekler için geliştirilen model cevap vermediğinden çözüm için iki farklı sezgisel önerilmiştir. Ayrıştırma (decomposition) yaklaşımı olarak isimlendirilen ilk yöntemde, geliştirilen model her mağaza için ayrı ayrı uygulanmıştır. İkinci sezgisel yaklaşımda problem ulaştırma modeline dönüştürülerek ele alınmıştır. Çözüm için iki aşamalı bir yöntem benimsenmiştir. Önerilen çözüm yöntemlerinin etkinliği, çeşitli boyutlardaki test verisi kullanarak karşılaştırmalı bir şekilde sunulmuştur. Elde edilen sonuçlar önerilen ulaştırma modeli temelli yaklaşımın devasa boyutlardaki gerçek hayat problemlerine kabul edilebilir zamanda ve her hangi bir ticari çözücüye ihtiyaç duymaksızın kaliteli çözümler üretebildiğini göstermiştir.

Published: January 2023

Enerji tüketimleri yüksek olan hastaneler birleşik ısı ve güç sistemleri olarak isimlendirilen kojenerasyon ve trijenerasyon sistemlerinin uygulanması gereken yerlerin başında gelmektedir. Bu çalışmada Kars'ta bulunan 276 yataklı bir üniversite hastanesine kojenerasyon ve trijenerasyon sistemlerinin uygulanabilirliği araştırılmıştır. Elektrik ihtiyacının sürekliliği ve birim fiyatının yüksek olması nedeni ile hastanenin elektrik ihtiyacına göre sistem seçimi yapılmıştır. Her iki sistemin planlaması elektrik ihtiyacının tamamını karşılayacak şekilde ve bu üretim sonucunda meydana gelen ısıtma ve soğutma çıktılarıyla hastanenin ihtiyacı olan ısının bir kısmının karşılanacağı düşünülerek tasarlanmıştır. Kojenerasyon sisteminin uygulanması ile yıllık 1.649.142 TL, trijenerasyon uygulamasıyla ise yıllık 1.661.105 TL net kar edileceği belirlenmiştir. Statik geri ödeme süresi kojenerasyon sisteminde 2,41 yıl, trijenerasyon sisteminde 3,86 yıl olarak, dinamik geri ödeme süresinin ise kojenerasyon sistemi için 2,85 yıl ve trijenerasyon sistemi için ise 3,13 yıl olarak bulunmuştur. Sonuç olarak Kars iklim özelliklerine sahip olan bölgelerdeki hastanelere her iki sistemin de fayda sağlayacağı, ancak trijenerasyon sistemlerinde ilk yatırım maliyetlerinin yüksek olması nedeni ile incelenen hastane için kojenerasyon sistemi uygulanmasının daha avantajlı olabileceği belirlenmiştir.

Media effects are one of the ten problems youths face today. Pornography is media content that causes a lot of negative effects on youth. Social media today exposes a lot of pornographic content that can be easily accessed by youth. At the same time, pornography among youth is a serious issue in Southeast Asian countries. Indonesia and Malaysia are countries in Southeast Asia with similar social and cultural backgrounds. The parents play an important role in preventing the impact of pornography among youth. Additionally, youth’s perceptions of pornography also play a role in shaping anti-pornography behaviours. This research aimed to analyse the influence of communication between parents and youth and youth’s perceptions of pornography on the formation of anti-pornography behaviour and attitudes. The population in this study were youth in 4 cities in Indonesia and Malaysia. This research used the cluster purposive sampling technique to determine samples from each cluster based on specific considerations (purposive), with an age range of 20-24 years. Based on the Slovin formula, the total sample obtained is 800 respondents. This study used path analysis as a data analysis technique. The results showed that communication between parents and youth did not have a direct and significant influence on the formation of anti-pornography behaviours. Meanwhile, youth’s perception of pornography has a direct and significant influence on developing anti-pornography behaviours. Most respondents thought that pornographic scenes on social media do not conform to religious values and that watching pornographic content on social media is addictive. Keywords: Pornography, anti-pornographic attitude, perception, youths, Indonesia and Malaysia.
Specifics of Appealing Headlines in Russian Mass Media Materials Dedicated to Science
Authors:   Ryazan State University named for S. Yesenin, Russia, Dolgova Natalia , Orekhova Yelena ,   Surgut State University, Russia
Published: January 2023

The article attempts to study the impact of headlines in science news and popular science messages in Russian in the news agencies, the Internet newspapers, on the websites socio-political media, as well as on the popular science sites. It is noted that the theme of science occupies one of the last places in the hierarchy of news content, which significantly limits the possibility of getting news data on the information agenda. Thematic varieties of effective headings are given, in which constants such as health, life safety, and sexual relations are distinguished. Linguistic and stylistic markers of clickbait headings are considered, among which quantitative numerals, colloquialisms, hyperbole created by using the epithet or the superlative degree of the adjective. The analysis of syntactic features leads to the identification of typical sentence schemes in which click-through ratio triggers are determined, forcing the user to turn to the article for details. The organicity of the appealing headlines of the concept of infotainment, which is a productive mechanism for popularising science on Russian popular science sites, is approved. It is indicated that the corpus of appealing headlines on these resources is characterised by individual author’s decisions embodied with the help of a comic mode, allusions, precedent texts and quotes, differentiation of the “image” of the addressee, oxymoron, antithesis and grotesque. In the system of popularising science, appealing headlines become organic components of news, gamified, and animated messages. Keywords: Headline, clickbait, popularisation of science, mass media, agenda.

High stigma toward COVID-19 sufferers was observed in Indonesia’s and Malaysia’s social media spheres, especially at the beginning of the pandemic in 2020. This study compared individual and interpersonal stigmas through analysis of online conversations and established government protocols in handling COVID-19 in Malaysia and Indonesia. The critical narrative found was ‘blaming others,’ pointing fingers toward other actors, such as certain ethnic and religious groups, for the continuous spread of the virus. We found that stigmatisation of COVID-19 in Indonesia and Malaysia pointed out jarring concerns, 1) lack of knowledge on COVID-19, 2) the need for effective and efficient dissemination of information to avoid victim blaming, and 3) politicisation of COVID-19 for one’s benefit. In times of public health crises such as COVID-19, governments should not only be responsive in formulating just policies that could help to control the spread of the virus but also mitigate stigmatization towards certain members of society. For Indonesian and Malaysian governments, while there were attempts to address COVID-19 stigma through various online and offline campaigns, observers expressed concern over the lack of recognition of the effects of stigma in COVID-19 official protocols. We discovered that COVID-19 protocols did not provide sufficient information on how to develop a safe environment for COVID-19 sufferers, thus preventing people from getting health treatment and other public services during the pandemic. Also, the protocols were found to have strengthened existing negative stereotypes toward marginalised groups. Keywords: Stigma, COVID-19, pandemic, Indonesia, Malaysia, Twitter.

The unethical activities related to weak political participation integrity on social media have influenced negative behaviours among supporters, particularly the young people. Social media transmits information on demonstration activities by enabling the creation, collection, and dissemination of false information or seditious libel, which exposes the country to external attacks and threats. Furthermore, young people’s negative political participation activities on social media, such as creating and disseminating false information, making harsh remarks, generating turmoil to acquire popularity or go viral, can potentially lead to cybercrimes. This research identified the impacts of media literacy competencies, namely access, analysis and evaluation, creation, reflection, and action, on political participation integrity among young people. This study distributed a survey to targeted university students in Melaka, Malaysia using the simple random sampling method. The students’ participation was purely voluntary. A total of 388 responses were successfully collected. The structural equation authenticated that four competencies significantly influenced the participants’ political participation integrity: access, analysis and evaluation, reflection, and action. In addition, young people who have media literacy skills showed a stronger preference to engage in political activities with higher moral conduct. The findings provided valuable insights about young people's political participation integrity on social media in Malaysia. Keywords: Media literacy competencies, political participation integrity, structural equation modelling, young people, social media.

Corporations are subjected to high criticism due to the misuse of Corporate Social Responsibility (CSR) communication to shelter their wrongdoing in running business activities. Obtaining trust from the local communities will increase corporations’ chances to earn Social Licence to Operate (SLO). Although communication is typically a two-way process, in communication research, getting a response from the targeted personnel is much more valuable. However, extant studies provide insufficient understanding related to communicative framework in engaging with local communities. Current research trends in CSR communication are skewed towards the effects of CSR communication, legitimacy of CSR communication, as well as the challenges in carrying out CSR communication. In this study, the current model of communication which is based on the mechanistic perspective of communication is discussed and expanded. Three important communication elements are analysed, and their relationship is proposed to form a new conceptual framework that includes a fourth element: opinion leader. The suggested framework primarily describes and provides arguments for the extent of communication willingness in affecting communication commitment. The crux of this framework is communication quality; transpiring in three formative factors namely bi-directional communication, symmetrical information and transparency. This framework believes that investigating the role of opinion leader in moderating the success of CSR communication adds empirical insights in the emerging literature of CSR communication. The discussed framework could be implemented in understanding dialogue between corporations and local communities. Keywords: CSR communication, opinion leader, dialogue, communication quality, local community.

International normative documents adopted in the field of software quality in Ukraine are characterized by "ability to maintain" and are defined as "a group of software properties characterized by the effort required to perform specific modifications." Modification of special software means any changes that are not adaptations. One of the sub-characteristics of the ability to support is analysis - "a subset of properties of the ability to support (SDR), which determines their suitability for diagnosing defects or failures and identifying parts to be changed and predict the consequences of these changes." Testing of SDRs after making changes to it is one of the many technological operations performed during maintenance. The level of testing, as a sub-characteristic of the ability to support, is influenced by the completeness and quality of software documentation, the availability of tools for generating test kits, as well as tools for analyzing test results; completeness of test kits and compliance with the rules of their compilation, which in turn determines the complexity of the testing process. The article shows the results of the assessment of the "ability to support" and "ability to move" special SDR automated information systems for military purposes. The metrics presented in the article allow us to evaluate and obtain numerical values of these parameters. Based on them, it is possible to compare the relevant programs for this quality characteristic. In addition, the paper considers metrics based on the analysis of the source texts of programs, graphs and supporting documentation, which provides a unified approach to automating their calculation.

The paper presents the results of theoretical studies of the influence of the main power parameters of the controlled suspension system on the longitudinal-angular oscillations of combat wheeled vehicles. An analysis was made of the nature of the conduct of modern armed struggle and the changed conditions for the use of combat wheeled vehicles. The relevance of increasing their mobility by improving the smoothness of the ride through the use of a controlled suspension system is substantiated. The analysis of well-known scientific and methodological approaches to describing the dynamics of wheeled vehicles is carried out. According to the results of the analysis, their imperfection was established. They are based on linear dependencies and do not allow taking into account the influence of the main power parameters of the controlled suspension system on the transverse-angular vibrations of wheeled vehicles. 40 A physical model of a combat wheeled vehicle and analytical dependencies for assessing the influence of the parameters of a controlled suspension system on the longitudinal-angular oscillations of combat wheeled vehicles are proposed. Unlike the known ones, the obtained dependences are non-linear and allow taking into account the influence of longitudinal-angular oscillations of combat wheeled vehicles. Based on the results of the analysis of the obtained analytical deposits, it was found that, in contrast to suspension systems with a linear law of the restoring force of elastic shock absorbers, for an adaptive suspension system, the natural frequency of longitudinal-angular oscillations depends not only on the static deformation of elastic shock absorbers, but also on the oscillation amplitude. It was also found that for combat wheeled vehicles with a controlled power characteristic of the suspension system, the amplitude of the initial perturbation of vibrations is greater for suspension systems with a large value of static deformation. A mathematical relation has been obtained to determine the amplitude of the initial disturbance of the longitudinal-angular oscillations caused by the collision of a combat wheeled vehicle on the unevenness of the supporting surface. The obtained analytical dependencies can later be used to create a software product necessary for the development of a controlled suspension system.

Recently, the importance of information support of medical technologies has increased. Widely used modern information technology, development and application of information technology is one of the urgent tasks. Most personal computers are used only for processing text documents, storing and processing databases, statistics, financial reporting. The article is devoted to the problems of choosing the optimal strategies for the treatment of viral diseases, which is quite an acute and urgent issue today. The aim of this study is to create an information system based on the architecture of a clinical diagnostic decision support system (DSS) that uses a knowledge base to assist the physician in his personal decision-making process. The developed software product will consist of several modules with characteristic functions: categorization of parameters and indicators according to the initial data of patients and division of the sample of the corresponding categories of parameters, selection of analysis and display of results. This system processes data and displays the results in the form of graphs showing the dynamics of changes in temperature of patients with prognosis. The system will provide information to the user, not the exact "answer", which was the purpose of their development. The user must analyze this information and discard erroneous or unnecessary information. He must be active and interact with the system, not just a passive recipient of information. User interaction with the system plays an important role in choosing how to use DSS. Modeling of health indicators is based on the mathematical apparatus of Markov chains. This technique allows you to calculate the sets of unconditional probabilities from the initial data and to make a probabilistic forecast of the health status of an individual or groups of the population for future periods of life.

The research of problems of construction of wireless sensor networks is carried out in the work, the main stage of their decision is development of models of the description of a sensor network and the corresponding methods, technologies of maintenance of necessary parameters of quality of functioning of a sensor network. The study involves the consideration of basic technologies and standards in which there is an opportunity to implement the creation of wireless sensor networks. The basis of wireless sensor networks are communication channels organized between network elements using appropriate wireless technology. The main tasks of building wireless sensor networks: determining traffic parameters; determining the list of services; development or selection of a network model; determination of network functioning indicators; solving the problem of compromise between the quality of operation, traffic and resources. A number of wireless networking technologies are widespread in corporate networks, use an unlicensed frequency band, and in private networks, which allows their use in a number of tasks, due to the density of devices that support them and the availability of technology. A number of technologies do not support the functions of self-organization of the communication network. Such mechanisms can be implemented using software and related protocols at the network level. Existing technologies have the ability to organize communication from tens to tens of thousands of meters. For specific applications, it is one of the essential factors in choosing the appropriate technology. The probability of connectivity in wireless sensor networks depends on the structure and parameters that determine the network: characteristics of the service area (volume, flat, configuration, geometric dimensions), number of network nodes, characteristics of communication capabilities of network elements, antenna patterns, standards and protocols, communication range, transmitter power), features of the involved routing protocols. Features of providing connectivity in wireless sensor networks lie in the possibility of using gateways built using various technologies, which can significantly expand the capabilities of wireless networks in increasing the likelihood of connectivity. A feature of the construction of wireless sensor networks are significant differences in traffic servicing in the networks of different technologies used. Indicators of the quality of wireless networks, such as bandwidth, delay, probability of loss are interdependent and show how effectively the sensor network works. When you change one of the performance indicators of wireless sensor networks, it affects other quality indicators.

End-Point (EP) Man-In-The-Middle (MITM) attack is a well-known threat in computer security. This attack targets the flow of information between endpoints. An attacker is able to eavesdrop on the communication between two targets and can either perform active or passive monitoring; this affects the confidentiality and integrity of the data flow. Several techniques have been developed by researchers to address this kind of attack. With the current emergence of machine learning (ML) models, we explore the possibility of applying ML in EP MITM detection. Our detection technique is based on Address Resolution Protocol (ARP) analysis. The technique combines signal processing and machine learning in detecting EP MITM attack. We evaluated the accuracy of the proposed technique using linear-based ML classification models. The technique proved itself to be efficient by producing a detection accuracy of 99.72%.
