Triboelectric generatorshave the ability to harvest energy from human activities, mechanical vibration, and other sources to drive minor electronic devices.In many circumstances, charges created from a triboelectric process are referred to as a negative effect or waste energy. Here, this paper will demonstrate an approach of the charging process in friction with a rotator and stator to investigate the effects of rotating speed and the different thickness of electrification to the output voltage. The 360° lateral sliding disc triboelectric generator (TEG) fabricated by connecting an Aluminium disc to the motor as a rotator, while a Polyvinyl Chloride (PVC) sheet placed at the top of an acrylic coated by a copper electrode served as a stator. PVC material with different thicknesses (0.2, 0.5 and 0.7 mm) and grit sizes were used (P500, P1000 and P1500) and prepared prior to the experiment. Thus, three different rotational speeds (500, 1000 and 1500 rpm) were monitored using a tachometer to standardize the speed for each set of experiment. Such as a TEG at 1500 rpm on a 0.2 mm thick sample with P500 grit size modification delivers a maximum voltage output, VRMSof 13.8 mV, with the maximum calculated current of 69 µA and the maximum power density of 0.485 mW/m2.

Catastrophic transformer failures are often attributed to corrosive sulphur-related faults. However, the existing challenge lies in the absence of practical, real-time monitoring techniques for sulphur corrosion, especially on-site. Previous studies have proposed the use of thin film sacrificial copper strip sensors as a promising solution to address this issue. Yet, their effectiveness in detecting corrosive by-products resulting from varying concentrations of DBDS breakdown remains unexplored. To bridge this knowledge gap, this study introduces an alternative technique that utilizes MATLAB software for linear interpolation and extrapolation. The findings demonstrate the capability of this technique to predict the ageing time of thin film sacrificial copper strip sensors when exposed to corrosive by-products derived from DBDS breakdown across a broad concentration range. This research aims to provide a valuable contribution towards enabling effective monitoring of sulphur corrosion and enhancing transformer maintenance practices.
A Hybrid Personalized Text Simplification Framework Leveraging the Deep Learning-based Transformer Model for Dyslexic Students

Published: December 2023

This study proposes a hybrid personalized text simplification framework leveraging the deep learning-based Transformer model to generate simplified expository texts by addressing all sentence perspectives: semantic, syntactic, and lexical. This study targets dyslexic students due to its increasing population in the education context. Dyslexia is a learning disability characterized by reading deficiency and cognitive weakness. Thus, they need a more personalized learning experience i.e., personalized text simplification to support their classroom learning. Unfortunately, the current models of personalized text simplification can only address the syntactic and lexical perspectives of sentences, ignoring the semantic perspective. Other models employed text complexity classification at the beginning of the text simplification workflow with the intention to address the personalization element. Still, no mapping to the deficiencies of its intended users was made, and the semantic perspective of sentences remains under study. Therefore, this study is conducted to introduce hybrid methods to enhance the current personalization elements, as well as to accommodate generation of simplified expository texts at all sentence perspectives. An extensive literature was conducted using established online databases. The proposed hybrid framework is further divided into three distinct phases: Phase 1) two-phase personalization, Phase 2) multi-label text complexity classification, and Phase 3) explicit editing. It is expected that a successful implementation of the proposed hybrid personalized text simplification framework can accelerate the learning motivations of dyslexic students, hence increasing their academic achievements and reducing academic dropout rates.

Published: December 2023

This paper presents research on an image processing approach for oil palm fruit brunches classification on automating the process of classifying palm fruit brunches based on their visual characteristics, which can have applications in the agriculture and palm oil industry. The research aims to classify the bunches into four categories which are unripe, under ripe, ripe and over ripe. Additionally, this approach can reduce the manual labour involved in palm oil grading and provide a more objective and consistent method for grading the oil. The proposed approach consists of the process of image acquisition, image pre-processing, colour processing, image segmentation and classification. The ripeness of the oil palm fruit bunches is determined based on the percentage of ripeness areas masked on the fruit surface. The proposed algorithms successfully classified the palm oil bunches and improved the accuracy of grading palm oil, achieving 85% accuracy from the experiment results.

Published: December 2023

Enteral nutrition is a nutrition therapy essential that provides a complete source of nutrition to malnutrition patients. Hence, dietitian will advise them for a complete diet. However, up to now, dietitians in Hospital Serdang are facing difficulties due to unsystematic storage information of enteral products, and they are required to memorize all the nutrients of the products. To overcome such issue, a MEP: Malaysia Enteral Product application for Dietitians was proposed to assist dietitian at Hospital Serdang. The MEP application was developed by using Agile methodology model. Agile was chosen because it is flexible and able to be modified if required. Functions such as searching, viewing, comparison and analyzing products were included. As an early observation, six dietitians from Hospital Serdang were testing the MEP. All respondents need to share their feedbacks by using a provided google form. Based on the feedbacks, all respondents agreed that the MEP application was able to provide precise enteral nutritional information and was able to reduce time, and energy during the evaluation and planning of enteral nutrition interventions for patients.

Published: December 2023

This paper considers the problem of task allocation where the goal is to find a coalition of UAVs (agents) to complete on-farm agricultural tasks. In this study, Ant Colony Optimization (ACO) algorithm is employed to find the best coalition of agents. The performance of the basic ACO algorithm for solving task allocation is improved by modifying the efficiency factor. In the proposed algorithm, the efficiency factor is defined as a function that relates not only to the capability of the agents and the distance between the agents, but also to the distance between the agents and the target. To solve the task allocation problem, the capability list of the agents was also adjusted using common UAV capabilities in agricultural application. Simulation results showed that the proposed ACO algorithm with the modified efficiency factor improved the performance of basic ACO algorithm for solving task allocation problem in terms of the average total travel cost for each agent. The optimum number of ants and agents in the proposed algorithm was also analysed for robust performance. Simulation results revealed that the addition of the numbers of agents and ants increases the average efficiency of the algorithm. In this study, we have also added a function to calculate the system capability utilization. By employing such a function, simulation results show that the total resource used by the agents and total communication cost can be optimized. In addition, a simple experiment using five ground robots with a centralized control was also carried out as a proof of concept for the proposed algorithm.

Published: December 2023

Актуальность настоящего исследования обусловлена тем, что прикладной характер направления подготовки 44.03.05 Педагогическое образование с точки зрения математических и физических наук относительно силен. Цель статьи заключается в обобщении и систематизации основных аспектов практико-ориентированной модели подготовки будущих специалистов в педагогическомвузе. Проведенный анализ литературных источников, посвященных вопросу практико-ориентированной модели подготовки учителей, позволил авторам раскрыть сущность данной модели и ее основные элементы. В процессе подготовки будущих педагогов должны использоваться современные методы обучения. Однако в реальной педагогической практике подготовка специалистов чаще всего осуществляется на основе традиционной модели преподавания, игнорирующей индивидуальные особенности студентов и необходимость практики в школах при непосредственном руководстве действующим учителем физики. Поэтому статья будет ориентирована на практику, в ней будут проанализированы меры по совершенствованию подготовки будущих учителей физики в высшем учебном заведении.

The relevance of the article is due to the fact that the practical and applied nature of the training program 44.03.05 is quite great from the point of view of mathematical and physical sciences. The purpose of the article is to generalize and systematize the main aspects of the practice-oriented model of training of future specialists in a pedagogical university. The analysis of the works devoted to the issue of a practice-oriented model of teacher training allowed the authors to reveal the essence of this model and its main elements. In the process of training of future teachers, modern teaching methods should be used. However, in real pedagogical practice the training of specialists is most often based on the traditional teaching model, which ignores the individual differences of students and the need for practice in schools under the supervision of a current physics teacher. Therefore, the article will be practice-oriented and will analyze measures to improve the training of future physics teachers in higher education.

Published: December 2023

Aim: The aim of this study was to investigate the pregnancy prognosis of patients taking beta-blockers for the treatment of cardiac arrhythmias.

Materials and Method: This study was a retrospective observational study involving 50 pregnant women with cardiac arrhythmias and 55 healthy pregnant women, admitted between January 1, 2020 and January 1, 2022, to Ankara City Hospital. Beta-blockers were classified into three groups: metaprolol, propranolol, and bisoprolol. The use of beta-blockers was examined in two groups: high-dose and low-dose. For pregnancy outcome, birth week, birth weight and birth weight Z-score, the bHCG MoM and PAPP-A MoM, neonatal APGAR score, and neonatal intensive care unit admission rates were determined. Statistical analysis was performed using IBM SPSS Statistics 26.0 (IBM Corp, Armonk, NY, USA). Shapiro-Wilk and Kolmogorov-Smirnov tests were both used to evaluate normality of variables. Groups were compared using the Student t-test and the Mann-Whitney U test. P-values < 0.05 were considered as statistically significant.

Results: The patient group taking beta-blockers had a statistically significant earlier delivery week than the group without beta-blocker use (p=0.000). The rate of primary cesarean deliveries was higher in the study group (p=0.007). Birth weight and APGAR score at the fifth minute was significantly lower in the study group, and NICU admission rate was significantly higher (p=0.006, p=0.000 and p=0.000, respectively).

Conclusion: Beta-blockers, a first-line therapy for maternal arrhythmias, may affect fetal development and pregnancy outcomes. İt is recommended that these drugs to be administered are meticulously selected for appropriate subgroups, with lowest effective doses

L’éducation spécialisée nécessite que le professionnel s’interroge sans cesse sur ce qui relève de la norme et du normal. La norme, étymologiquement l’équerre, la règle ou la loi est une notion essentielle qui permet aux professionnels de se situer par rapport aux publics, de faire repère. Le normal fait appel à nos représentations, aux codes sociaux en vigueur ou encore à une interprétation et à une mise en scène « située » de la norme. Mais quand les codes sociaux fluctuent, quand les modes relationnels dévient, quand le quotidien dérape, il est difficile de se rappeler où se situe la norme et le professionnel fait appel à l’habitude.

Published: December 2023

Réflexion partagée entre usagers et professionnels des secteurs sanitaire et social, la démarche réflexive des participants est double. Ceux-ci se sont engagés, en premier, dans une approche conceptuelle de la notion d’autonomie. L’objectif est d’acquérir une compréhension partagée de ce concept pour mieux considérer la multiplicité singulière des vécus. En second, le partage de vécus quotidiens, relevant de témoignages d’usagers, est venu illustrer les difficultés que ceux-ci rencontraient au quotidien. Ce qui ne pose pas problème à chacun peut devenir une véritable épreuve pour celui qui est en situation de handicap. Cet article met en lumière ce que, parfois, les professionnels finissent par oublier, accaparés par les contraintes qui sont les leurs. Il révèle également ce que nombre d’usagers n’osent exprimer. Pour autant, il s’agit de rester attentif à celui qui est différent. Cet engagement doit permettre le respect d’un droit commun.
Les normes : l’inséparabilité du collectif et de l’individu
Authors: Pichon Isabelle

Des règles rigides, imposées par d’autres et quasiment immuables sont des stéréotypes des normes. Bien que nous soyons spontanément enclins à imiter les autres, nous évoquerons qu’un besoin d’appartenance incite l’individu à suivre des normes. Pour autant outre la finalité d’un besoin d’appartenance, nous discuterons de leur usage comme moyen pour changer nos attitudes ou nos comportements, qu’ils soient signes d’émancipation ou d’aliénation.

Published: December 2023

Devenus de véritables réceptacles des savoirs culinaires, les sites numérisés de cuisine ont évolué grâce aux avancées technologiques ainsi qu’aux changements socio-culturels. L’article analyse comment la transmission se réalise, pourquoi les grandes étapes de la cuisine sur Internet influencent les modes de transmission et quels sont les facteurs de changement. Ces supports permettent aux mangeurs d’accéder en permanence à des recettes enrichies de fonctionnalités, de se les approprier, de les modifier au gré des retours d’expérience et, dans une moindre mesure, d’apporter leurs contributions en déposant des recettes personnelles. Cette dynamique de transfert et de contre-transfert portée par les communautés des sites, est la spécificité d’une nouvelle approche de la cuisine et constitue le noyau d’une révolution dans la transmission des savoirs culinaires.

Published: December 2023

Persons with severe mental illness (PwSMI) are at risk of being victimized due to persistent cognitive, emotional, and behavioral symptoms, which can become potential threats for effective reintegration into the community. A total of 217 PwSMI, receiving outpatient psychiatric treatment from a tertiary hospital, were screened for abuse, and if they were identified as abuse, then information about contextual factors contributing to abuse, sociodemographic, family, and clinical and legal profiles was created. Overall, 150 PwSMI were victimized, of which 56% were females, 50.7% were married, 20.7% were educated up to middle school, and 31.4% were homemaker. The most common form of diagnosis was schizophrenia (43.3%), with a mean duration of illness of 14 years. All the victimized PwSMI were subjected to emotional abuse. PwSMI were more likely to be victimized by multiple family members due to poor knowledge and understanding about illness (24%). The majority of the PwSMI had disclosed abuse (62.7%) to nonformal sources (33.3%) with no documentation in the clinical file (82.7%). PwSMI experience ongoing abuse and are more likely to be re-victimized, which increases the need for regular screening and culturally sensitive and comprehensive community-coordinated care and support.
Efficacy, Tolerability, and Superiority of Propylene Glycol-Free, North American Witch-Hazel (Hamamelis virginiana)-Based Solution of 5% Minoxidil Sulfate for the Treatment of Female Androgenetic Alopecia
Authors: Trüeb Ralph Michel
Published: December 2023

Background:

Androgenetic alopecia leads to progressive hair loss in susceptible individuals if left untreated. Topical minoxidil represents an evidence-based treatment for female androgenetic alopecia, though with variable success.

Aims and Objectives:

Treatment of minoxidil non-responders remains challenging, as does treatment of patients with propylene glycol sensitivity or irritable scalp syndrome.

Materials and Methods:

Single-center, retrospective cohort of 50 female patients with androgenetic alopecia failing to respond to a minimum of 6 months of standard 5% topical minoxidil solution either once daily or b.i.d. depending on the severity of the alopecia. Patients were switched to propylene glycol-free, North American Witch Hazel (Hamamelis virginiana)-based solution of 5% minoxidil sulfate (5% minoxidil sensitive solution). Efficacy and safety of treatment were evaluated, including stereotactic global photography and epiluminiscence microscopy with digital imaging taken at baseline, at 3, and at 6 months of treatment.

Results:

70% of patients showed observable clinical improvement with combined global photographic and epiluminiscence microscopic assessment with digital imaging, and 22% epiluminiscence microscopic-only improvement as evidence of treatment efficacy. The treatment was well tolerated, particularly in patients with propylene glycol sensitivity and patients with irritable scalp syndrome.

Conclusions:

These results suggest that propylene glycol-free, North American witch hazel (Hamamelis virginiana)-based solution of 5% minoxidil is effective and safe for treatment of female androgenetic alopecia, specifically in minoxidil non-responders and patients with propylene glycol sensitivity or irritable scalp syndrome.
Nivolumab-Induced Lichen Planopilaris: Case Report and Literature Review of Hair Disorders Associated with Targeted Oncological Therapies
Authors: Asfour Leila , Rutkowski David , Chaudhry Iskander H. , Harries Matthew J.
Published: December 2023

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapies. Their mechanism promotes a cytotoxic T-cell activation against the tumor cells, but as a consequence, immune-mediated toxicities are increasingly being identified. Cutaneous immune-mediated adverse events (AE) occur in 32% of patients, with possible higher grade AEs seen with anti-programmed cell death protein 1, such as nivolumab. A 67-year-old woman with metastatic melanoma, previously treated for 2 years on dual ICI (ipilimumab and nivolumab), had her treatment interrupted due to grade-3 hepatitis. She was subsequently recommenced on single-agent nivolumab with good response, before discontinuation due to remission. She reported worsening scalp pruritus with associated erythema, scaling, and global hair thinning. On examination, she had significant erythema throughout the scalp with perifollicular scaling and evidence of scarring. She reported severe distress from her symptoms. Her scalp biopsy demonstrated features of scarring alopecia with infundibular and isthmic inflammation and interface change in keeping with lichen planopilaris. Follicular toxicities are rarely reported, possibly due to imprecise AE phenotyping or underreporting. However, growing evidence suggests that patients can develop follicular pigmentary changes and nonscarring alopecia. To our knowledge, this is the first case of scarring alopecia reported with nivolumab. Current treatments for ICI-induced toxicities are limited.
Optic Nerve Avulsion from Optochiasmal Region Secondary to an Animal Attack: A Case Report
Authors: Kaya İ
Published: December 2023

ABSTRACT

Optic nerve avulsion without bone fracture was observed in four cases in the literature. This case is unique with its cranial effects and complications. A 50-year-old Caucasian female patient attacked by an animal on her left eye was admitted. Traumatic subarachnoid hemorrhage in the suprasellar cistern and epidural hematoma was observed upon brain computed tomography (CT). Enucleation and duraplasty were performed on the patient whose epidural hemorrhage did not increase. Two weeks after being discharged, the patient presented to the emergency room again with numbness on the right side of her face and sensory aphasia. The patient was followed up by medical treatment with left temporoparietal infarction and had completely recovered. Optic nerve avulsion secondary to trauma is a topic that needs to be carefully investigated due to potentially fatal complications. This article was written to share our experience with this rare condition and its case management.

Published: December 2023

ABSTRACT

Background:

Problems related to quality of life and body images of amputee patients are important.

Aims:

This study was performed to assess body image and quality of life with problems experienced of patients with lower limb amputation.

Materials and Methods:

This study was performed using mixed quantitative dominant study design. The study was carried out in orthopedics and cardiovascular surgery units of a university hospital. Quantitative data were collected from 30 patients via questionnaires including the Short Form-36 Quality of Life (SF-36 QoL) and Amputee Body Image Scale (ABIS) tools. Qualitative data were gathered from 20 patients using an interview form. In this research, quantitative data have been analyzed by using a statistical program and qualitative data have been analyzed by using content analysis.

Results:

Age mean of 30 patients with amputation 47.23±16.08. They were 80 % male, 70% have a chronic illness, 63.3% knee disarticulation or transfemoral amputation, and 53.3% use prosthetic. The average SF-36 QoL sub-dimension scores of the patients were: physical 30.11±20.00, social 36.66±27.45, physical roles 18.33±30.03, emotional roles 37.77±22.71, mental health 48.0±22.89, vitality 36.50±20.64, pain 48.13±28.33, and general health 43.96±28.59. The ABIS average score was 60.1±19.62. The most common problem of patients after amputation involves issues related to motion. Three main categories of patients experience with amputation were designated that the reactions after learning that the amputation will be done, problems experienced in the early period after amputation and post-discharge problems.

Conclusions:

Quality of life of patients with amputation was below the intermediate level. Deterioration in body image perception was above average. The most common problem after amputation was issues related mobilization. Training related the amputation process and social support might significantly reduce problems with amputation.

This is a cross-sectional comparative study done at Alex Ekwueme Federal University Teaching Hospital, Abakaliki, Nigeria. Consecutively selected stable term neonates whose mothers consented to the study and met the inclusion criteria had their CDs measured with both calipers and smartphones and the values compared. Mean, range, and standard deviation were calculated using Statistical Package for the Social Sciences (SPSS) IBM (version 22), while paired t-test calculated the difference in mean CD measurements between both methods. Pearson’s correlation and Bland–Altman’s analysis determined the correlation and agreement between both methods, respectively. Inter and intraobserver repeatability were assessed. A P value less than 0.05 was taken as statistically significant.

Results:

The mean CD measurement using calliper method was 10.01 ± 0.29mm and 10.03 ± 0.24 mm right eye (RE) and left eyes (LE), respectively) for investigator 1 and 10.16 ± 0.25 mm and 10.19 ± 0.21 mm (RE, LE) for investigator 2. Using smartphone measurement, mean CD measurements of 9.98 ± 0.21 mm and 10.00 ± 0.29 mm (RE, LE) were observed for investigator 1 and 10.07 ± 0.19 mm and 10.06 ± 0.21 mm (RE, LE) for investigator 2. The difference in mean CD for both instruments and by both investigators was not statistically significant (P value > 0.05).

Conclusion:

Corneal diameter measurement in neonates using smartphone technology does not deviate significantly from caliper measurement; it is safe, easy to use, and advocated.

Published: December 2023

In the first part of this work we have established an efficient method to obtain a topological classification of locally discrete, finitely generated, virtually free subgroups of real-analytic circle diffeomorphisms. In this second part we describe several consequences, among which the solution (within this setting) to an old conjecture by P. R. Dippolito [Ann. Math. 107 (1978), 403–453] that actions with invariant Cantor sets must be semi-conjugate to piecewise linear actions. In addition, we exhibit examples of locally discrete, minimal actions which are not of Fuchsian type.

By the consumption area of the Nis branch, annual activities due to the maintenance of the 35 kV transmission line are carried out in accordance with the Annual Plan of the maintaining activities of elements of DEES, as well as the Annual Plan of drive interruption of elements of DEES. The implementation of the those activities reduces the probability of the occurrence of emergency situations. However, emergency situations inevitably occur, as per the unwritten rule on 35 kV radial transmission lines, and,also, at a time when the weather conditions are such unfavorable that the regular maintaining activities are significantly more difficult or practically impossible. The teams of the Maintenance Compartment are not always able to carry out the regular activities on repairing the emergency situation on the transmission line. Those situations demands alternative solutions in order to enable urgent re-supply of consumers. Some of the technical solutios are sugested in further text.

If underground, metallic, insulated pipelines are run in parallel in long lengths, or intersect at a small angle with high-voltage lines, due to the alternating current flowing through the overhead line in everyday operation, induced voltages occur in the pipelines, i.e. there is the potential difference between the pipeline and the surrounding soil. In case the pipeline insulation is damaged and there are some coating defects, leakage currents occur from the surface of the pipeline into the surrounding soil. These leakage currents further lead to the accelerated occurrence of metal corrosion. As a consequence, there may be complete corosion of the metal from which the pipeline is built and spillage of the liquid being transported through the pipeline. This paper deals with the examination of the threshold level of parallel running of overhead power lines and pipelines, after which the level of corrosion on the pipeline exceeds the permitted values and endangers the lifetime of the pipeline. This paper analyzed the influence of the choice of the type of overhead line tower, conductor, as well as the distance at which the pipeline and the overhead line go in parallel.

The paper describes the application of the BIM (Building Information Modeling) methodology, which represents a new approach in the design of buildings, which, unlike the traditional one, provides opportunities for easier sharing of information and monitoring the state of the project from the design phase, through construction to maintenance and management. Certain countries of Europe as well as other countries of the world have already introduced the obligation to apply this methodology on projects financed by the state, with the aim of better monitoring of the situation, greater transparency, easier communication between different engineering disciplines and greater efficiency.bThe paper explains the basics of BIM through an example of an overhead power line project for the purpose of understanding and application, and how the methodology can be applied to power line projects regardless of the voltage level.

Abstract—The existence of telecommunication lines in the nearby should be considered with the design of overhead transmission line. Due to the permanent load on power lines, induced electromotive force, noise and interference voltage occur in telecommunications lines. For this reason, these impacts must be carefully investigated in order to implement adequate protection measures. This paper presents an analysis of the impact of power lines on telecommunications lines, using the example of a report that considered the impact of the 2x400 kV power line Transformer Station Bajina Basta – border of Bosnia and Herzegovina/ border of Montenegro on telecommunication lines. The analysis has been done in accordance with JUS N.C0.101 and JUS N.C0.102 standards. In order to simplify calculations, TeleCAD-GIS software package was used in the analysis. At the end of the paper, solutions that can reduce the effect of power lines on telecommunications lines will be discussed.

Authors: Kurniawati Henny Tri , Sudiarto Budi
Published: December 2023

The presence of increasingly sophisticated and innovative cooking utensils such as induction cookers has changed the way of cooking by providing a high level of efficiency. Induction cookers are also a breakthrough in reducing carbon emissions and making them an important choice in energy conservation efforts. The use of induction stoves in the community still faces several obstacles such as relatively high prices, significant power consumption, and the need for special cooking containers. In addition, the development of induction stove technology can produce electromagnetic emissions in the form of conduction emissions. Conducted emission is electromagnetic interference caused by electronic devices through conductors which can be interpreted as noise currents that propagate on the conduction path and have the potential to interfere with other electronic equipment through voltage sources. In the same power grid, conducted emissions caused by induction stoves can also interfere with data signals using Power Line Carrier (PLC) at a frequency of 30-500 kHz. This study aims to understand and identify patterns of electromagnetic wave emission, namely conduction emissions produced by induction stoves. The main focus is on conducted emissions, which can affect the performance of such electronic devices. The results of research related to the characteristics of the conducted emission value of this induction stove are expected so that this household device is safer and more comfortable to use by the community and can provide a reference for the further development of induction stove technology. The test method was carried out on 4 (four) brands of induction stoves C, A, M and P under various operating conditions and cooking modes both individually and simultaneously in the frequency range of 9 KHz-30 MHz through Electromagnetic Compatibility (EMC) testing. The measured parameter is a Quasi Peak (QP) value, in accordance with CISPR standard 14.1:2020. Based on measurements in the frequency range of 9 kHz-30 MHz, individual conditions were obtained that some of the induction stoves used in this study were above the threshold values required in CISPR 14.1:2020. Based on measurements with the condition that the induction stove is operated simultaneously, the level of conducted emission decreases and there is a disturbance at a new frequency beyond the disturbance frequency at individual conditions.
