Abstract

Ethiopia's rapid expansion of urbanization, industrialization, modernization, and population growth has led to an insistently increase in the demand for wood for construction, furniture, and other end products. This study aimed to investigate the effect of tree height and the diameter tree section (sapwood and heartwood) on the density and mechanical properties of Casuarina equisetifolia timber. For this study, ten sample of C. equisetifolia trees were selected and harvested from Bishoftu, Oromia Regional State, Ethiopia. The collected sample logs were sawn into 3-cm-thick lumber, and sample specimens were prepared for density and mechanical properties testing. Sample specimens of heart and sapwood sections were prepared from the bottom, middle, and top portions of the tree for testing density, static bending (MOE and MOR), compression strength parallel to the grain, impact bending strength, and hardness strengths in tangential and radial directions according to ISO standards. The results revealed that tree height had significantly affected density and hardness strengths in tangential and radial directions. On the other hand, the diameter section (heart and sapwood) significantly affected the density, impact bending, and hardness strength in the radial direction. On the contrary, tree height and tree diameter section didn’t show a significant effect on MOE, MOR, and compression strength parallel to the grain. Due to the high density of Casuarina equisetifolia wood, it is very hard to convert into lumber, and the lumber is also difficult to machine. Based on the basic properties studied, Casuarina equisetifolia wood could be used for wood flooring, chipwood, particleboard, furniture, and other products such as tool handles.

Abstract

Online collaborative learning has become an essential component of higher education, offering students opportunities to engage in peer-based learning activities. Peer assessment, as a tool for enhancing collaborative learning, has demonstrated significant potential but also presents several implementation challenges. The primary objectives of this paper are to identify and analyze the key challenges encountered in the implementation of peer assessment within online collaborative learning environments. This study employed a mixed-methods approach, combining qualitative and quantitative research methods to explore the challenges faced in implementing peer assessment in online collaborative learning environments. Approximately 35% of students in our study reported difficulties related to the peer assessment platforms, including usability issues and limited integration with other learning management systems.35% of students in our study found the assessment rubrics unclear or insufficiently detailed. The challenges identified in this study, particularly those concerning technological limitations, lack of training, and issues with fairness and trust, have significant implications for the implementation of peer assessment in online collaborative learning. Based on the results and expert review, it is clear that overcoming these challenges requires a multifaceted approach. Technological, pedagogical, and social challenges all play a role in hindering the effectiveness of peer assessment, but these challenges can be addressed through targeted strategies.

Abstract

Electrical resistivity is a fundamental property of materials, reflecting their ability to conduct electricity and playing a critical role in electrical engineering and material science. This experiment investigates the effect of conductor length on resistivity using a single metallic wire with lengths ranging from 10 cm to 60 cm. Resistance was measured for each wire length using a calibrated voltmeter and ammeter, and resistivity was calculated using the relation Equation 1. Experimental conditions were meticulously controlled, with consistent wire material, steady environmental temperature, and precise wire diameter and length measurements to ensure accuracy. The results demonstrate a direct relationship between wire length and resistance, validating the theoretical prediction. The calculated resistivity of the metallic wire was 2.04 x 10-8 Ω⋅m, closely aligning with the theoretical value for silver (1.59 x 10-8 Ω⋅m) and supported by the wire's shiny gray appearance. This experiment highlights the practical application of resistivity in selecting materials for electrical systems and offers a valuable hands-on approach to teaching resistivity concepts in the classroom. The findings can be integrated into physics education to enhance students' understanding of material properties, data analysis, and electrical circuit principles.

Abstract

Ceramic insulator components have high popularity because the majority of electrical distribution systems in Indonesia use ceramic insulators. Ceramic insulators have advantages in mechanical strength, but the nature of the surface material makes it easy to absorb water, which can accelerate aging and increase leakage current when used in high-pollution areas. This research will test the effect of salt and fly ash contaminants on the leakage current characteristics of ceramic insulators. Furthermore, it will be tested the effect of nano coating on the leakage current characteristics of ceramic insulators. Tests were conducted to analyze the leakage current characteristics on the insulator surface due to the influence of contaminants by varying the ESDD and NSDD values of contaminants with light, medium, heavy, and very heavy categories on the ceramic insulator surface. The results show that the higher the NSDD level and ESDD level of salt and fly ash contaminants, will increase the leakage current value. The test results of nano-coated ceramic insulators prove that they can reduce the value of leakage current. In testing ceramic insulators coated with nano coating materials contaminated with salt with a very heavy pollutant category, it is proven that the leakage current value is reduced by 23.5%. Testing ceramic insulators coated with nano coating materials contaminated with fly ash with a very heavy pollutant category proved that the leakage current value was reduced by 23.7%. Benefit-cost analysis is used to assess whether the nano-coating project on ceramic insulators is feasible or not feasible. The results of the analysis show that the Benefit Cost Ratio (BCR) value is obtained from the total present value benefit divided by the total present value cost, so that the result is 1< or more than one. The nano-coating project on ceramic insulators from the BCR parameter is feasible to implement.

Abstract

This research examines the correlation between workplace automation and employee performance, focusing on the interplay between AI technologies and human contributions. The study uses a descriptive research approach and focuses on a population of workers from diverse sectors, such as banking, healthcare, and manufacturing. A sample size of 300 respondents was established via Krejcie and Morgan’s technique, and data were gathered through structured questionnaires sent via internet channels. The questionnaire included sections on demographic data, kinds of AI technologies used, and their reported effects on productivity, work satisfaction, and task efficiency. Validity and reliability were established by expert evaluations and a pilot study, with Cronbach's Alpha computed to evaluate internal consistency. The data study used statistical methods like descriptive statistics, correlation analysis, and multiple regression analysis using SPSS to assess the impact of AI tools on employee performance and the interplay between AI automation and human contributions. The findings demonstrate a substantial positive correlation between AI tools and employee performance, with AI contributing to 53.6% of the variation in performance. The data demonstrates a strong synergy between AI automation and human efforts, accounting for 62.3% of the variation in performance results.  These results highlight the need to amalgamate AI technologies with human competencies to augment productivity and cultivate a cooperative work atmosphere. The report advocates for continuous training and a learning culture to maximise the advantages of AI in the workplace, ensuring people see AI as an enhancement tool rather than a substitute.

Abstract

Diabetes is a major public health problem worldwide, and early diagnosis will remain pivotal for intervention and management. This Systematic Literature Review (SLR), therefore, attempts to explore the prospects of integrating Machine Learning (ML) and Digital Twins (DT) to enable diabetes treatment through prediction and patient-specific modeling. This SLR contributes to the body of literature by examining how ML and DTs are being applied in diabetes treatment, identifying the opportunities and challenges that exist, and determining which algorithms are most commonly used. In contrast to SLRs that have been reviewed previously, this study considers Digital Twin-based technological perspectives, along with algorithmic evaluations of ML models, to provide an overall view of the potential for combined use in diabetes care. Following PRISMA guidelines, 11 relevant studies were selected from major academic databases. The study identified Random Forests, Gradient-Boosted Decision Trees, K-Nearest Neighbors, Time Series and Structured Analysis, Regression-based algorithms, and Artificial Neural Networks as machine learning algorithms commonly used to predict diabetes risk. The integration of ML and DT for diabetes management enables the personalization of patient management through virtual representations, real-time monitoring of an individual's glucose levels, simulation of disease progression, and prediction of subsequent treatment steps for proactive and immediate decision-making. Through this collaboration, simulations of various situations are performed, and the interventions are optimized to correspond with unique human physiological profiles for better patient outcomes. Based on the results, policymakers must balance data quality and patient privacy.

Abstract

The investigation probed the structure of the material of the brake shoe, the roughness of the surface, and wear behavior to understand its influence on system efficiency. Regression analysis and Design of Experiments (DOE) were utilized to examine dependencies of variables. The findings indicate that Al₂O₃ significantly improves thermal stability and wear in wedge-type and disc brakes. In addition, the optimal choice of sliding velocity, normal load, and temperature can produce better braking and reduced wear. These results are important in developing more efficient and durable brake systems for automotive, aerospace, and industrial applications. The study also emphasizes the importance of the design and material composition of brake shoes for obtaining ultimate brake performance under several operating conditions.

Abstract

Soil erosion in semi-arid regions contributes significantly to groundwater contamination, particularly through sediment-laden runoff entering shallow aquifers. The intensification of rainfall events has accelerated surface erosion, leading to increased transport of sediments and contaminants into shallow wells, which serve as the primary water source for many households. This study investigated the extent and mechanisms of groundwater contamination in twelve selected wells around Kwarin Awaja, focusing on changes in water quality before and after major rainfall events. Water samples were analyzed for turbidity, electrical conductivity (EC), pH, coliform bacteria, nitrates, and heavy metals (cadmium and chromium). Results showed significant increases in turbidity, nitrates, total dissolved solids, chloride, sulphate, and electrical conductivity after rainfall, indicating erosion-induced pollutant infiltration. Paired sample t-tests revealed significant post-rainfall increases in turbidity (up to 12.1 NTU) and EC (up to 675 µS/cm), with values exceeding national standards such as Nigeria Standards for Drinking Water Quality (NSDWQ) in wells closest to active erosion sites. Pearson correlation analysis showed strong associations between proximity to erosion features and elevated pollution indicators. Microbial contamination, absent before rainfall, was detected in several wells after rainfall events. The findings highlight the vulnerability of shallow groundwater to erosion-driven pollution and underscore the need for targeted interventions to protect water quality in erosion-prone rural environments.
