SYNCHRONIZATION: IDENTICAL AND NON-IDENTICAL INVESTIGATION OF RUCKLIDGE SYSTEM
Authors: Tarammim Absana
Published: June 2024

This article explores the impact of synchronization, both identical and non-identical supporting systems with six different Co-efficient Matrices, on the Rucklidge chaotic system. Two paired chaotic systems are proposed to synchronize using the Active Control Algorithm (ACA). Six sets of different control functions originating from identical and non-identical Master/Drive systems. All synchronizing design demonstrates that six sets of different control functions are always perfectly applied and chaotic systems are significantly synchronized with six different co-efficient Matrices. Parameters are similar across identical pairings of chaotic systems however must be different for non-identical pairs. The feasibility and efficacy of synchronizing the state variables are derived from the error dynamics coefficient matrix. We analyze the effectiveness of synchronized identical and non-identical approaches to explore which control functions would provide better results. The non-identical pair is formed utilizing the Harb-Zohdy chaotic system with a unique initial value. In addition, numerical simulations are offered to validate and expand upon the theoretical findings.
COMPARATIVE ANALYSIS OF A REDUNDANT SYSTEM SUBJECT TO INSPECTION OF A MANUFACTURING PLANT
Authors: Kaur Harpreet
Published: June 2024

The present paper is a comparative analysis of a two-unit autoclave system in a manufacturing plant. Most of the studies have been done by considering standby units to remain as good as new ones in this mode, but practically they may be corrupted by any environmental issues. This fact makes us concerned about the standby unit. Two stochastic models were developed based on such concern. Model 1 is constructed based on basically two possibilities; firstly, the standby unit is inspected after a fixed amount of time to check its feasibility. Secondly, either it will be repaired or replaced. Replacement is instant. Model 2 is constructed based on the same assumptions but replacement is not instant, it takes some random amount of time to be replaced. Stochastic analysis uses Markov processes to investigate how these dynamic factors interact and impact system profitability, availability, and dependability. By studying various scenarios about repair prices, replacement costs, inspection frequency, and fluctuating demand patterns, this research provides vital insights into the most effective approaches for handling redundant units and preserving system functionality. The results guide managing complex decision-making processes for safeguarding and maximizing system functionality, which has practical ramifications for sectors and systems that depend on redundancy to guarantee continuity and reliability.
FEATURE SELECTION USING EXTRA TREES CLASSIFIER FOR PARKINSON’S DISEASE CLASSIFICATION
Authors: Sabherwal Gauri
Published: June 2024

Parkinson's disease (PD) is chronic, permanent, and life-threatening. Neurologically protective treatments for PD rely on early detection. Recent studies have demonstrated that clinical data, cerebrospinal Fluid (CSF) based proteomes, and gene mutations are important biomarkers for accurate and early detection of PD. This study aims to investigate the heterogeneous data comprised of CSF-based clinical data, CSF-based proteomic analysis data as well as the mutation information of the genes, Glucose Beta Acid (GBA), leucine-rich kinase (LRRK2) to classify controls into PD-affected and Healthy Control (HC). The dataset contains 1103 controls (569 PD affected and 534 HC). Automated Machine Learning (AutoML) framework using PyCaret is utilized. The study has proposed an Extra Tree Classifier (ETC) as a feature selection mechanism to select features that significantly affect the PD classification. Selected features are further used to train Random Forest (RF), Logistic Regression (LR), and Decision Tree (DT) classifiers. Accuracy, sensitivity, specificity, area under the receiver operating characteristic curve (AUC-ROC), and the confusion matrix are used to evaluate the performance of classifiers. RF has depicted the best performance in terms of accuracy value of 96.12%, sensitivity of 95.59%, and specificity of 95.34% while LR has shown the highest AUC value of 98.33. RF has made the highest number of correct predictions 316 out of 331.

BEYOND BOUNDARIES: UNLEASHING 6G’S TRANSFORMATIVE WAVE IN INDIA
Authors: Mittal Shivek S.
Published: June 2024

India is a developing country in terms of both technology and infrastructure. Since India is already pursuing its research in 5G and is already using the 4G network, but the problem that Indian citizens have with the current mobile network infrastructure can’t be properly solved even by the upcoming 5G, so here we need to think about why we are talking about 6G in such an early stage. Not only because of the great network bandwidth and low latency of the features of 6G, or why we say that 6G will be a game changer for Indian mobile network infrastructure because of features like maximum spectral efficiency that’s up to 1000 km/hours and peak data rate that’s up to 1 Tbps, which is twice that of 5G and nearly quadruple that of 4G. In this paper, we discussed what the main advantages are. What are the problems faced by Indians, why these problems are caused, and how 6G can solve them? We also provide the questions that we asked the people (mainly the youth of India). In addition, our paper also suggests a project idea that provides a technological solution to teachers’ and professors’ wasted time at schools or colleges attending this conference

Authors: Wlazło Marcin
Published: June 2024

Celem artykułu jest przybliżenie na wybranych przykładach zjawiska, któremu nadano miano pop-inkluzji. W najnowszych serialach (zarówno całkiem nowych, jak i w kontynuacjach) można zaobserwować uniwersalny schemat tworzenia świata przedstawionego, w którym obowiązującą zasadą staje się takie zróżnicowanie głównych i drugoplanowych postaci, które wprost we wzorcowy sposób odzwierciedla założenia społeczeństwa włączającego. Szczególną uwagę zwraca sposób prowadzenia wątków osób z niepełnosprawnościami, których obecność jest jedynie jednym z wielu przypadków maksymalnego zróżnicowania cech charakteryzujących bohaterki i bohaterów danej produkcji. Pop-inkluzja odnosi się do specyficznego i coraz powszechniejszego wykorzystania tematyki inkluzywnej w kulturze popularnej. W konsekwencji należy się zastanowić, na ile stała wręcz obecność zagadnień inkluzywnych w najnowszych serialach wiąże się z przemyślanymi działaniami popularyzatorskimi w tym zakresie. Chodzi zatem również o nowe rozważanie dydaktycznych (pedagogicznych) aspektów tekstów kultury popularnej.

Authors: Wu Da-Wei , Batool Hira , Huang Shi-Zheng
Published: June 2024

Cultural authenticity is the core resource of ethnic tourism destinations, and tourists' perceptions of cultural authenticity affect their sense of authentic happiness. Based on cognitive appraisal theory, a research model of perceptions of cultural authenticity and authentic happiness was constructed to explore the relationships among perceptions of cultural authenticity, place attachment, and authentic happiness and to verify the moderating effect of perceived safety. Through a questionnaire survey, 408 valid questionnaires from tourists were collected from ethnic villages in border areas of China, and the bootstrap method and parameter estimation method were used to test the hypotheses. The results show that cultural authenticity perception positively affects authentic happiness and place attachment; place attachment has a direct positive correlation with authentic happiness; place attachment has a partial mediating effect on the perception of cultural authenticity and authentic happiness; and perceived safety has a moderating effect on place attachment and authentic happiness. Attaching importance to the excavation and protection of the cultural authenticity of frontier ethnic villages and enhancing tourists’ perceptions of the cultural authenticity of frontier ethnic villages are conducive to promoting their place attachment to frontier ethnic villages and, at the same time, can enhance tourists’ sense of authentic happiness. Doi: 10.28991/HEF-2024-05-02-07 Full Text: PDF

Published: June 2024

This study investigates the relationships between sustainable human capital management practices, ESG performance, ESG disclosure, and firm financial performance. Using a sample of 387 S&P 500 firms from 2013 to 2023 and a panel data regression approach, we examine the impact of training expenditure, workforce diversity and inclusion, pay equity, and employee benefits on ESG performance. We also explore the association between ESG performance and ESG disclosure, the effect of ESG performance on financial performance, and the moderating role of ESG disclosure in the ESG-financial performance relationship. Our findings reveal that sustainable human capital management practices have a positive and significant impact on ESG performance, which in turn positively influences firm financial performance. We also find a positive relationship between ESG performance and ESG disclosure, and that ESG disclosure moderates the ESG-financial performance link, with the positive association being stronger for firms with higher levels of ESG disclosure. This study contributes to the literature by offering an integrated approach to examine the relationships between sustainable human capital management, ESG performance, ESG disclosure, and financial performance, providing novel insights into the drivers and outcomes of corporate sustainability in the context of human capital management. Doi: 10.28991/HEF-2024-05-02-08 Full Text: PDF

Gunung Palung National Park (GPNP) has a diversity of ant, but the information as a source of learning is still lacking. This study aims to determine the diversity of ant species in the TNGP area and its potential as a source of learning. Research using descriptive qualitative method. Sampling used a pitfall trap placed on a line transect that passes through an alluvial soil forest. Collecting data on potential learning resources using the results of a questionnaire. The results showed that there were 90 individuals from 9 ant species specifically Dinomyrmex gigas, Polyrhachis bihamata, Rhytidoponera araneoides, Dolichoderus thoracicus, Axinidris Acholli, Hagensia havilandi, Myrmicaria brunnea, Anonychomyrma myrmex, Notostigma carazzii. The diversity of species of ants has the potential as a source of learning with indicators of clarity of potential (85%), ease of access (58.33%), security (91.66%), time efficiency (75%), cost (91.66%), suitability with learning objectives (100%), clarity of material objectives (100%), and clarity of information disclosed (100%). This research shows that information about ant diversity is very suitable as a source of learning biology, especially in the subjects of biology, biodiversity, and the classification of living things.

This study aims to evaluate the impact of the CTL model on cognitive and learning activities of fifth-grade students at SDN 16 Banda Aceh, particularly when their cognitive scores in heat transfer topics in science do not reach the minimum threshold (KKM) of 76. This quantitative research uses a one-shot case study design with measurement and observation sheets as instruments. The analysis shows that the average student score before using the CTL model was 80.76 with 72.73% classical completeness, and after using the CTL model, it was 76.33 with 69% classical completeness. Hypothesis testing indicated t count > t table (2.49 > 1.69), thus H1 is accepted. Average cognitive scores were C1 = 22, C2 = 27, and C3 = 31. The instructor's task average score was 4.74 (very good), and student learning experiences were 85% very good, 9% good, and 6% acceptable. The results indicate that the CTL model positively affects individual cognitive outcomes with an average score of 80.76. However, it does not significantly impact the percentage of classical completeness, which remained at 72.73%, below the required 80%. The CTL model enhances teacher and student learning experiences, making students more engaged and enthusiastic as the learning connects directly to their lives.

Population increase has an impact on the procurement of food sources. Pakcoy is a vegetable that is in increasing demand. Farmers' response to this condition is to use excessive fertilizer and pesticides, thereby reducing soil fertility. The research aims to obtain a combination of fertilizer and humic acid, which is effective in cultivating B. rappa chinesis L., as well as soil conservation efforts. The methodology was experimental with Randomized Block Design (RBD) on four treatments, K, P1, P2, and P3. The dose of K was 150 g/5 m2, NPK 16:16:16, 1 kg/5 m2 dolomite, and 5 kg/5 m2 manure. The P1 treatment is the same as K but without NPK fertilizer. P2 and P3 treatments were reduced by 50% and 70% of NPK fertilizer, respectively, with the addition of humic acid. The research results show that P2 with local environmental conditions provides optimal results in terms of chlorophyll, stomata, and plant height. Soil fertility was shown by increasing pH to 6.6, K 281 ppm and P 509 ppm, Cation Exchange Capacity (CEC) 31.60 cmolc/kg, soil enzymes of 0.12 mg FDA g-1 soil d.w. h-1, an average number of earthworms of 17. The conclusion is that P2 fertilizer formulation can be applied to cultures as an anticipation of food security.

Natural Sciences (IPA) emphasizes students' science process skills in every learning process. However, looking at the facts in the field when studying science, students still tend to memorize concepts, theories, and principles without understanding the discovery process. This has an impact on the ongoing learning process being uninteresting so that students become bored and ultimately causes students' understanding of science concepts to become low. This research aims to determine the quality of science process skills of class VII students at Kanda Middle School. The research method used is quantitative. The population is all class VII students at Kanda Middle School, totaling 46 people, while the sample in this study was 23 students taken by random sampling. The instruments used are performance that assesses practicum activities as well as interview guidelines used to gather information from science teachers. Data were analyzed using the percentage value formula. This research concludes that the science process skills of class VII Kanda State Middle School students have a percentage of 70.01% in the skilled category.
