Published: January 2024

This study embarks on developing predictive models for soil shear strength parameters, cohesion (c) and angle of internal friction (ϕ), in Bishoftu town, employing Artificial Neural Networks (ANN). It aims at offering a cost-effective and time-saving alternative to traditional, often expensive, and labor-intensive laboratory methods. The research utilizes soil index properties such as Sand %, Fines %, Liquid Limit, Plastic Limit, and Plasticity Index to construct separate ANN models for c and ϕ. These models use a multi-layer perceptron network with feed-forward back propagation, varying the number of hidden layers to optimize performance. The study's dataset comprises 316 soil test results, encompassing both primary and secondary data, conforming to ASTM Standards. Soil cohesion and internal friction angle were determined using the direct shear box method. The models demonstrated remarkable success in predicting shear strength parameters, evidenced by correlation values of approximately 0.99 for cohesion and 0.98 for internal friction angle, surpassing the capabilities of existing empirical methods. Further examination of the models included comparison with existing correlation techniques and cross-validation using primary soil test data. This validation process confirmed the ANN method's superior accuracy and fit for predicting shear strength parameters over selected empirical methods. This research substantiates the efficiency of ANN in geotechnical engineering, particularly for areas with limited resources for extensive soil testing. It establishes ANN as a powerful, efficient tool for estimating soil shear strength parameters, with significant implications for future planning, design, and construction projects in similar environments.

The Tarentaise breed in Tunisia is gaining prominence, yet comprehensive field studies on it are limited. This research aimed to delineate the breed's unique production and reproductive characteristics in Tunisia, assess non-genetic influences on milk production, and evaluate genetic progress under current management. Analyzing 345 lactations from two herds, we identified the main sources of variation in milk traits. Average milk yield, fat percent, protein percent and days in milk were 3022 kg ± 1532 kg, 3.52 ± 0.51, 3.50 ± 0.59, and 214.69 d ± 111 d, respectively. The average daily milk production was 14 kg ± 6 kg. Key findings revealed significant advantages in winter calvings and highlighted that some cows peak in performance by their sixth lactation, suggesting untapped potential. There was more than 700 kg between cows that calved in January and if the same cow calved in summer season, in favor of winter calvings. Alarmingly, both herds showed a reliance on sires with negative milk breeding values, potentially hampering genetic milk traits. Introducing tailored adjustment factors for the Tarentaise breed, our study underscores the need for optimized management to harness its full milk-producing prowess in Tunisia.

This project is about developing an educational game for kindergarten children. Educational games for kids are designed to teach important concepts such as numbers, letters, colours, shapes, and more in a fun and engaging way. They can also help develop important skills such as problem-solving, critical thinking, and creativity. Mathematics is a challenging subject for most children at an early age, especially preschoolers. This is due to the lack of understanding, interest, and successful ways to help them learn. Typically, mathematical games are presented with an emphasis on entertainment or education. Games can be an effective way to teach children mathematics. They can also help foster a positive attitude towards the subject, which can lead to better learning outcomes. Thus, creating an educational mobile game would be an excellent solution to this problem. This project aims to create a mobile game that can be installed on mobile phones or tablets to teach children mathematics. The RAD (Rapid Application Development) model will be used as the project methodology to conduct this project. First, the functional requirements were determined. Then, the prototype was developed and named Jungle Math. A field usability test was conducted with the targeted users to evaluate the application's ease of use. The findingssuggest that the application is ready to be used in a learning and fun environment for kindergarten children upon the success of the trial run, as the targeted users found the application easy to use and enjoyed playing and learning with the application.

Urban composition has exacerbated precipitation patterns. Rapid urbanization with dynamic composition and anthropogenic activities lead to the change of physical environment, especially land-use and land cover which subsequently magnifies the environmentaleffects such as flash floods, extreme lightning, and landslides. Due to extreme and elevated temperature trends with exacerbated rainfall patterns, these environmental effects become major issues in tropics. Albeit several studies pointed out that rapid urbanization induced precipitation, studies about the heterogeneity of urban composition on precipitation variables are still limited. Thus, this paper reviewstudiesaboutprecipitation pattern in relation to the heterogeneity of urban composition that successfully integrates geographical information system (GIS) and remote sensing techniques to enhance the understanding of interactions between precipitation patterns against heterogeneity of urban composition. This article also addressed the current state of uncertainties and scarcity of data concerning remote sensing techniques. Evidently, with a comprehensive investigation and probing of the precipitation variables in the context of urbanization models fused with remote sensing and GIS, they put forward powerful set tools for geographic cognition and understand how its influence on spatial variation. Hence, this study indicated a great research opportunity to set the course of action in determining the magnitude of spatial heterogeneity of an urban composition towards the pattern of precipitation.

The integration of technology in the planning practices of the Malaysian construction industry has significantly transformed how planners approach the development process. The objective of this research is to examine the extent to which technology has been adopted in planning practices in Malaysia. To accomplish this, a mixed methods approach was used, which involved distributing an electronic survey form to the members of the Malaysian Institute of Planners(MIP). The study has revealed three important findings.Firstly, for software adoption rates, the majority of respondents used basic storage, communication, CAD, graphic design, and GIS software with varying skill levels. On the other hand, hardware adoption rates were lower, likely due to financial constraints, and most respondents had average skills in operating GPS, drones, remote sensing, cloud computing, and 3D printing hardware. Secondly, the annual budget for most organisations was below RM30,000, with software subscriptions accounting for the largest budget allocation. Lastly, financial resources, a lack of skilled workers, and network constraints were identified as the biggest challenges faced by planning agenciesin adopting technology. The research suggests that providing grants for technology adoption for small firms and local authorities, standardisation of systems, and flexible data sharing can increase productivity in planning activities across agencies. In summary, planners must adapt to technology due to the increasing demand for new development. Effectivedata management is required for decision-making. Malaysia’sgovernment and planners are willing to adopt technology for increased productivity, and recent developments such as I-Plan and OSC 3.0 Plus Online demonstrate a commitment to data-driven decision-making. There is still much to learn and improve for planners in the public and private sectors to contribute to the success of the construction industry in Malaysia.

In Japan, the application of the prestressed concrete (PC) system has become quite popular, especially in bridge and building constructions. Since it was first introduced in the early 1950s, the number of buildings using the PC system has substantially increased. However, following a certain period in the service life of the PC system, the serviceability of such structures especially following an earthquake has become a primary concern, especially when exposed to severe corrosion-prone environments. In this research, the City Hall building of Nandan Town, Awaji Island in Japan, was chosen to investigate the influence of corrosion on the durability of the building structure, which was initially constructed in1957 as the first building that used PC members for beams. This paper describes the building and results of the field crack inspection and corrosion test results on concrete core samples from the building. Accordingly,the study found that the building had material deteriorations due to its corrosive surrounding environment and severe damage on the concrete cover of the PC anchorage.

Building information modelling (BIM) adopters require well-documented, quantitative, and financial simulation studies as solid evidence for the benefits of BIM to implement it and evaluate its success.However, to move towards more practical analyses to be performed by the end-users, more discussions on process to measure BIM benefit should be held, despite the large number of studies related to BIM benefit indicators. Therefore, this study examines the proposed and simulated methods used to measure the benefits of BIM in previous studies. A systematic literature review (SLR) of 21 articles was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and analysed using meta-ethnography and thematic qualitative analysis. The SLR depicted the trends of studies published over the years. The results indicate that out of the 31 BIM benefits identified, only 17 BIM benefits have been measured in simulations.4 other BIM benefits were suggested to be explored in line with their magnitude of importance.Comparative case studies were used conventionally to collect the data for measuring these benefits. This has since shifted to conducting case studies of single BIM projects along with supplementary data collection for counterfactual assessment. Furthermore, predictive ex-ante studies are currently blooming. At present, ongoing studies are being conducted to demonstrate thedetailed technique with which to calculate and measure the benefits of BIM.This paper providesresearchers and analysts with initial insights that can be used to move forward with BIM benefit measurements.

Military training and periodical assessment are essential in preparing a well-built soldier physically and mentally for the Malaysian Army Forces. One of them is the water survival training test. The test consists of a series of aquatic tasks conducted in a remote area. As a matter of fact, it requires a water-pool facility which is durable and portable. Therefore, this research aims to design and prototype a modular portable swimming pool for floating exercises and assessment for military personnel. The study is conducted in partnership with the Royal Army Engineers Regiment, with the objectives being to design, simulate, prototype, and build the modular portable swimming pool for military uses. The study output wastested, evaluated, and appraised on the swimming pool workability on site. The methodology is divided into 4 phases; (i) Content Studies and Design Profiling, (ii) Digital Prototyping, Evaluation and Testing, (iii) Physical Prototyping -Materials and Method; and (iv) Application and Measurement. The study seeks to maximise the training of military personnel and reduce the transportation time and resource costs of building a permanent pool by placing it with a modular portable swimming pool, which is more cost-efficient and user-friendly. The findings of Phase 1 prototyping required improvement on design structure where it indicated disadvantages in sustaining water volume ability at targeted level due to structural integrity. Upon improvement of Phase 2 prototyping using metal with bracing framethe pool are able to sustain the desired water volume at 5200 l3. Moreover, this study, also responds to the approaches of the Sustainable Development Goals (SDGs) 9, 16 and 17 towards harmonizing and interconnecting the three core elements of sustainability, economic growth, social inclusion, and environmental protection for human well-being.

Baking soda is a valuable element for development because it not only helps in the food industry but can directly help in the construction industry. To make it, the alkaline component of sodium bicarbonate is combined with acid salts and corn starch. Baking powder is a chemical substance with the formula 𝑁𝑎𝐻𝐶𝑂3 that is used in baking. This compound is a member of the salt group and has been used for a very long time. The main retarder additives are divided into several categories according to their chemical composition, including Lignosulphonic Acid and Hydrocarboxylic acid and their salts. In this experiment, baking soda was used as a cement replacement in concrete. The purpose of this study is to determine the workability, water absorption and compressive strength of concrete with variations in the cement replacement with the baking soda of 0%, 3%, 6%, and 9% of the weight of cement. This is an experiment in the study of upgrading building materials on construction sites. Porosity and compressive strength samples in the form of a concrete cube are used to test for water absorption and strength. The outcomes from this research are the result of slump value for 3%, 6%, and 9% are 31mm, 35mm, and 43mm respectively. For water absorption test, the highest percentage of water absorbed is 9% of baking soda followed with 6% and 3%. The highest compressive strength obtained from this research is the concrete cube that contained 3% of baking soda followed by 6% and 9%. Based on the results obtained, it is proved that baking soda can increase the workability of concrete. When baking soda content is increased, the percentage of water absorptionwill increase.

Soil reinforcement is the geotechnical application for the soil mass reinforcement elements to increase the shear characteristics of the soil grid. Bamboo is a sustainable source for the wood industry that has been applied in construction soil foundations as a soil reinforcement material. The use of bamboo types Dendrocalamus asper for soft soil reinforcement stability is important and commonly used. Peat, as a very soft soil, is known as problematic soil, and organic soil has poor shear strength and high compressibility. In construction especially for peat soil foundation or subgrade, it has settlement and deformation because of loss of strength. The peat soil from Kampung Puteri Menangis, Benut Pontian Johor has been used in the experimental work to determine the displacement of the settlement performance characteristics without and with the laminated beams of bamboo Dendracalamus asper. Without bamboo, the displacement of the settlement reduces from 22.4% to 6.8% within 1 hour. The use of 1 layer of laminated bamboo reinforcement on the foundation base reduced the displacement of the settlement from 27.2% to 8.9%. The displacement continuesto decrease from 19.3% to 5.8% fortwo layers of laminated bamboo reinforcement, and 18.9% to 5.9% for 3 layers of laminated bamboo reinforcement. At each stage and duration, the peat shows displacement in compression, and the settlement of the reinforcement stability is smaller than in the other stage.

Malaysia’s construction industry has been long characterized as risky, as evidencedby its poor health and safety performance. The statistics on fatal accidents recorded by the Department of Safety and Health Malaysia (DOSH) present that struck by accident in the Malaysian construction industry have the highest number of deaths and were one of the critical contributor. Therefore, this study was done to find the main contributing factor to the struck by accidents and its preventive measures. The questionnaire was distributed to the respondents, who were experienced safety personnel in construction industry with at least 10 years’ experience in handling safety and health at the workplace. From the questionnaire survey, the most significant contributing factor to struck-by accidents is carelessbehaviour, and the main perceived prevention measure for struck-by accident is job hazard analysis or job safety analysis briefing to workers before starting job. The outcome of the study could provide awareness on struck-by accidents and reduce the risk of struck-by accident by objects in the construction industry in Malaysia.

Carbon Fiber Reinforced Polymer (CFRP) considered as unique material as it is proven have the best mechanical properties which can be used as a wrapping. This composite material will be evaluated as a wrapping material using Solidwork version 2021 software. Elbow has been chosen as component to be wrapped as it is one of the most critical parts in a pipeline system. Thus, this research focuses on 90-degree butt welded elbows. The study evaluated different lamination and thickness of CFRP as a wrapping framework for elbows. Static analysis also was stimulated to analyze the stress and strain exerted on elbows at extrados location. Based on static analysis simulation from Solidwork software, lamination orientation of (0º) with 6 layers exhibit lowest stress for all the pressure tested ranging from 0.86MPa to 19.65MPa for 90-degree defected elbow at extrados location. Besides, comparing CFRP and Glass Fibre Reinforced Polymer (GFRP), CFRP showed it able to reduce stress compared to GFRP when tested on the same defected elbow. Lastly, the flow simulation in CFD showed there were no leakages especially on defected area and no sudden changes on pressure, velocity, and temperature.

Computer-numerical control (CNC) machining has become the norm in most manufacturing businesses. In order to maximize machining efficiency, prevent unintended damage, and maintain product quality all at once, tool wear measurement is essential. Wear on the tools is typically an inevitable side effect of machining. Because it endangers the machining process, flank wear, the most frequent type of tool wear, should be avoided. This study's objective is to fill this growing need by developing a system that can use machine learning to monitor tool condition during the turning process using MATLAB. The regression method with boosted decision trees and SVR with Gaussian kernels are applied to predict the flank wear based on the vibration signal and cutting parameters. This study found that the regression with boosted decision tree method has a lower mean average percentage error, 6.43%, while SVR is 10.11%. Plus, R2 for regression is slightly better than SVR. It shows that the system successfully produced an accurate prediction of flank wear.

Corrosion under insulation (CUI) refers to external corrosion that appears between carbon steel piping or pressure vessels’ external surfaces underneath jacketed insulation. There are many factors affecting the CUI corrosion rate. The chance of CUI exhibits a higher value between 50ºC and 175ºC. Understanding the corrosion rate at critical temperatures is important in assessing insulation performance and preparing maintenance plans. It is challenging to predict the CUI rate in a real working pipeline. A laboratory simulation following ASTM G189-07 is a laboratory scale to study and provide an alternative method for determining CUI corrosion rate at a controllable working temperature. At 80ºC, the CUI corrosion rate is lower than the CUI rate at 75ºC. The result shows that the corrosion rate on the carbon steel pipeline is not perpendicular to temperature.

Carbon steel plate with single vee butt welded was inspected with an ultrasonic flaw detector (UTFD) using an angle probe. Various types of couplants have been used to study their effects on ultrasonic transmission. The acoustic impedance of the couplant affects the transmission of ultrasonic waves. As a result, welding flaws were found on the root and central area of the butt weld plate. The results also show that honey has the smallest percentage difference (234.42) in terms of size accuracy compared to water (362.89) and baby oil (370.04) in identifying and measuring defect size. However, there are other factors to be considered when performing an UTFD testing. In summary, UTFD is the only method of NDT that can detect and measure all subsurface defects in the weld area, and honey gave the best results for the couplant used.

In this study, the input factors (PVC, rattan, plantain peduncle, and temperature) and the responses (flexural strength and modulus of elasticity) of an experimental design to reinforce PVC composite were investigated. The assessment of suitability and ultimately the choice of the models were done based on the values of statistical parameters like coefficient of determination (R2 value), p value, F value, etc. The experimental data was carried out by fitting a second-order model in the Design Expert model library to the data to estimate the unknown model parameters. This process was accomplished by applying multiple regression analyses to the data. The optimum values of the responses were obtained by numerical optimization based on the criterion of desirability. The results obtained showed that the design was adequate, and the models developed from it were useful because the off-diagonal values were close to zero. Also, increasing the proportion of PVC resulted in a steep and significant increase in the flexural strength of the composite. More so, this trend was similar to the flexural strength for the response surface and the corresponding contour plots representing the relationship between PVC, rattan, and modulus of elasticity. Besides, at higher temperatures, the PVC material could act as a binder, which results in a strong interaction between the components of the composite material.
