The Evaluation of Pulsed Eddy Current Technique for Detection and Characterization of Surface Defect in Carbon Steel Welded Sample: An Experimental Study
type: item
description: Pulsed Eddy Current (PEC) is an advanced Non-Destructive Testing (NDT) method based on the principles of electromagnetic induction which generate square wave form. This study was carried out to investigate the surface defect that occurs in carbon steel welded sample (ASTM A36) and to investigate the signal profile of a transverse crack orientation with different defect depths which are 1mm, 2m, 3mm, 4mm and 5mm. A total of five test samples have been used to execute this study with different defect depths. MATLAB is used to generate the result and from the result, it shows that transverse crack is inversely proportional where the deeper the crack, the lower the magnetic field where the magnetic field dropped by 3.54% from 1mm to 2mm of defect depths. However, 3mm of defect depth decreased by 5.55% when compared to 2mm. Meanwhile, with defect depths of 4mm and 5mm, each magnetic field reduced by 2.59% and 4.91%, respectively. This is due to the changes of relative permeability and electrical conductivity of the test sample after welding process been done and affected the magnetic field that acquired. Therefore, it shows that PEC is an effective method of NDT in order to detect the surface defect carbon steel.

An Artificial Neural Network with Bayes' Theorem (Hybrid) for Automated Bearing Faults Diagnosis
type: item
description: Bearing fault diagnosis plays a pivotal role in the realm of condition-based maintenance, with vibration spectra analysis standing out as a highly effective method for discerning issues in rotating machinery. Various signal processing tools, including wavelet analysis, empirical mode decomposition, and Hilbert-Huang transform, have been employed to scrutinize vibration spectra. However, these methodologies often necessitate human expertise to ensure optimal outcomes. In the pursuit of automated fault diagnosis, machine learning tools such as Artificial Neural Networks (ANN) and support vector machines (SVM) have emerged as viable alternatives. Over recent decades, considerable research efforts have been devoted to exploring the viability of employing Artificial Neural Networks (ANN) for automatic fault diagnosis, resulting in predominantly positive findings. Nevertheless, the accuracy of Artificial Neural Networks (ANN) is intricately linked to factors such as the neural network structure, encompassing considerations like the number of nodes, hidden layers, and the choice of activation function. Addressing this challenge, the present study introduces an innovative hybrid algorithm for automated bearing fault diagnosis, integrating Artificial Neural Networks (ANN) with the Bayes’ Theorem (BT) theory. The hybrid algorithm exploits Bayes’ Theorem (BT) theory to augment fault diagnosis results derived from Artificial Neural Networks (ANN), specifically by alleviating conflicting outcomes generated within the neural network. The study focuses on characterizing four conditions of bearings, namely a healthy state and three distinct fault types: rolling element, inner race, and outer race faults. Through the proposed hybrid algorithm, working in tandem with artificial neural networks, a demonstrated superiority is established, surpassing the results obtained by Artificial Neural Networks (ANN) in isolation. This pioneering approach not only underscores the potential for hei…

Ergonomic Risk Assessment for Manual Handling Activities in Automotive Workshop
type: item
description: Ergonomic risk assessment tools are tools that have been designed to solve the problem of ergonomics in the workplace from manual material handling activities. The objective of this study is to investigate Musculoskeletal Discomfort among workers related to manual handling activities using Cornell Musculoskeletal Discomfort Questionnaires (CMDQ); to assess an ergonomics risk factor among workers related to manual handling activities using Manual Handling Assessment Chart (MAC), NIOSH Lifting Equation(NLE), and Key Indicator Method for Manual Handling Operation (KIM-MHO) method and; to compare the results between CMDQ and assessment tools. This case study was conducted in Parit Raja, Johor, Malaysia involving 34 male mechanics workers. The tools used are as stated in the objective with the help of measurement tools such as a goniometer. The result of the CMDQ reveals that the body part with the highest discomfort level among the workers in the lower back, shoulder right and shoulder left with the percentage from the total discomfort score of 20.91%, 13.57%, and 13.36% respectively. From the result of the assessments, it is concluded that the highest risk factor contributing to the MSDs is the bad posture of the worker during the manual handling operation followed by the frequency of lifting and the weight of the load. By comparing assessment tools, the first comparison is made between the CMDQ versus KIM-MHO, MAC Tools and NLE. In this comparison that, it is highlighted the result type from CMDQ are different from the KIM-MHO, MAC Tools and NLE as its questionnaire result shows us the discomforts levels on the body of workers and the body parts affected on their body for the last seven days but the assessment tools results show us the risk factor that contributes to the MSDs. For the comparison between the three assessment tools, it can be said that the tools that have the highest correlation with CMDQ are MAC Tools. In conclusion, most workers suffer from MSDs in th…

Commercial Aircraft Selection Decision Support Model Using Fuzzy Combinative Multiple Criteria Decision Making Analysis
type: item
description: Multidimensional decision-making issues invariably entail a profusion of factors and dimensions necessitating consideration. In such intricate environments, decision-making can be notably challenging. To navigate this complexity, the realm of multiple criteria decision-making approaches is indispensable, helping in unraveling convoluted predicaments. This paper introduces a novel approach fuzzy combinative multiple criteria decision-making analysis — crafted to address fuzzy decision analysis challenges. At the heart of this method lies the utilization of the Euclidean distance as the primary measure and the rectilinear distance as the secondary measure, both calibrated in accordance with the negative-ideal solution. Determining the desirability of alternatives rests on these distances. Further augmenting the evaluation, the process involves combining the Euclidean and rectilinear distances through fuzzy combinative multiple criteria decision-making analysis. The efficacy and stability of the fuzzy decision analysis are underscored through a numerical example, illustrating the proposed method's procedural nuances. A comparative analysis comparing both Euclidean distance and rectilinear distance with the weighted sum model and the weighted product model is also conducted. This scrutiny underscores the efficiency of the proposed method while affirming the reliability of its outcomes.

Stochastic Frontier Analysis of Selected Nigerian Seaports Container Throughput’s Efficiency
type: item
description: This paper measures efficiency of container throughputs across the selected terminals within the selected seaports using input-output efficiency ratio. For a terminal to be productive does not mean it is efficient. There are forms of efficiencies as allocative, economic and technical. All round pass mark of efficiency in this regard has to do with minimum time spent within the system of a port for a particular transaction. This research has been able to determine the efficiencies of container throughputs across terminals within five major seaports in Nigeria with collected secondary data (2012-2022) from Nigerian Bureau of Statistics on container cargo throughputs for Apapa, Tin Can Island, Onne, Calabar, Port Harcourt and Warri terminals. The total inputs containers throughputs in (tonnes) from different terminals within a port were aggregated together to constitute an input for terminals within a seaport. The input variables are number of ships per annum, cargo handling equipment (cranes) (TPC) and dock workers (ngh). Stochastic Frontier Analysis with the aid of R-software has been used to analyse the collected data It was observed that terminals at Onne are most efficient followed by Calabar. Tin can Island terminal efficiency was a slightly higher than that of Apapa as both had a little above average mean efficiency value. Warri terminals are the least while Rivers was not considered for unavailability of data. There are other factors responsible for inefficiencies of mostly the western terminals at Apapa, Tin Can and Warri Eastern terminals which can be investigated further in future research.

Omnidirectional Battery Electric Vehicle for Use in Oil Palm Plantation
type: item
description: Concerns on the low labour shortage and the need to reduce greenhouse gas (GHG) generation prompted the industrial player to increase mechanisation during operation and adopting low carbon footprint mobile platforms. In this paper, a design and analysis study was conducted and reported on a conceptual battery electric vehicle (BEV) for use in the oil palm plantations. With a maximum operating road speed of 30km/hr and harvesting load of 320kg, the BEV will require a minimum operational power of 44.5kW. In accommodating the soggy ground with the demand to navigate narrow and undulating terrains, the proposed BEV was designed to be equipped with an omnidirectional functionality with continuous track, without the use of conventional wheels. Major components arrangement and design for the omnidirectional mechanism are presented in this paper. This preliminary work will also serve as the foundation towards refining the BEV design, especially on the vehicle functionality and manoeuvrability in the plantation sites. Further recommendations are also outlined that will focus on validating the conceptual design and analysis on the total energy generation and consumption of the BEV.

Unveiling the Environmental and Economic Implications of Additive Manufacturing on Inbound Transportation
type: item
description: This study aims to investigate the impact of additive manufacturing (AM) on the sustainability of inbound transportation. By combining insights from existing literature and interviews with professionals in the additive manufacturing field, we present a comprehensive analysis of this subject. Drawing upon both literature review and interview perspectives, it is evident that AM significantly influences the sustainable dimension of transportation. A key attribute of additive manufacturing is its inherent efficiency, resulting in minimized waste generation during production. This stands in contrast to traditional manufacturing methods, which involve material reduction to achieve desired shapes. The streamlined process of additive manufacturing requires fewer raw materials, thereby reducing environmental impact. The transportability of filament powder in bulk form further contributes to these sustainability gains, reducing material volume and transportation frequency. Consequently, emissions associated with additive manufacturing-related transportation are lowered. Recycling of materials is also structured within a broader framework, deviating from the conventional model of product returns to manufacturers. Despite its potential, our empirical findings suggest that the adoption of additive manufacturing doesn't consistently lead to cost reduction compared to conventional methods. The applicability of additive manufacturing remains limited to specific product ranges. Nevertheless, cost savings can occur in the realm of inbound transportation due to factors such as reduced transportation frequency and the transport-friendly nature of raw material containers. Furthermore, the efficiency of raw material usage in additive manufacturing contributes to economic benefits. Unlike conventional manufacturing, additive processes don't require extensive raw material inventories. Economic considerations extend to the adoption of distributed manufacturing systems. While centralized sys…

Sustainable Electrical Discharge Machining (EDM) Of Inconel 718 When Using RBD Palm Oil Based Dielectric Fluid
type: item
description: Electrical Discharge Machining (EDM) involves the discharge of a series of discrete sparks from a high-voltage electrical arc between the metal and the workpiece, therefore removing the metal. This experimental research aims to evaluate the material removal rate (MRR), electrode wear rate (EWR), and surface roughness (Ra) of an Inconel 718 and a copper (Cu) electrode while using a sustainable electrical discharge machining (EDM) method with the usage of either a modified bio-degradable or traditional dielectric fluid. RBD palm oil has been trans-esterified to achieve the same viscosity concentration as kerosene fluids. In this study, the influence of peak current from 6A to 12A and Pulse duration from 50?s to 150?s on the machinability performance were investigated. Scanning Electron Microscope (SEM) was used to examine the surface topography of Inconel 718 and electrode surface morphology. The result shows that at highest Ip=12A and the lowest ton=150?s yield the highest MRR for those RBD palm oil, modified RBD, and kerosene dielectric fluid. The improvement of MRR for RBD palm oil and modified RBD as dielectric fluid is about 46.82% and a decrement of 8.89% when compared to kerosene at the same parameter settings. Meanwhile, machining by using RBD palm oil, modified RBD, and kerosene at Ip =6A and ton =150µs yields the lowest EWR and Ra respectively. However, the value of EWR and Ra for RBD palm is slightly higher compared to kerosene and modified RBD. In the case of machinability, RBD palm oil shows the best results in the EDM machining of Inconel 718.

Characteristics and Preliminary Study of Ceramic Concretes
type: item
description: One of the most adaptable and frequently used building materials in the world is concrete. It is flexible in terms of size and shape, sturdy, long-lasting, low-maintenance, fireproof, and easy to use. However, further research is needed to increase the durability and sustainability of this material since concrete technology is still in developing industry. Therefore, it's crucial to comprehend how microstructure and characteristics interact in terms of how they affect concrete's strength, dimensional stability, and durability. The findings of this research are crucial in identifying the properties and characteristics of the ceramic concrete used for bridge construction or others. Advanced research to ascertain the hardness and physical qualities and features of ceramic concrete material is required. Thus, it will help to produce a reliable data for engineer to refer for their future works or project. To ascertain its hardness and physical characteristics, research has been conducted on ceramic concrete for several types of grades. In the current study, the ceramic concrete was tested through the physical and Vickers-hardness tests. The X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) on samples were performed to observe the phases and morphology of the ceramic concrete, respectively. For results of physical testing, the density and water absorption correlate to each other by the denser of the sample, the lower of water absorption and the porosity level of the ceramic concrete. Based on the Vickers micro hardness test, it can be seen that longer curing days affected the hardness, where the concretes of grade 30 and 40 at 28 curing days had better hardness value. Next, Scanning Electron Microscopy (SEM) on samples shown almost same microstructure, while the dominant phase of all ceramic concrete grades was SiO2 by the XRD analysis. In summary, better properties of ceramic concretes were indicated at 28 curing days for both grades of ceramic concretes.

The Development of a Vehicle Recovery Remanufacturing Tool: An Interior Parts Analysis Indicator
type: item
description: The rapid growth of the automotive industry has placed a significant demand on earth resources such as metal and minerals. This has led to a shortage of materials and an increase in material prices. One of the solutions to enhance resource management is to perform parts remanufacturing during product design to ease the part classification. However, this initiative is not yet widely explored, particularly in terms of guideline or tool development. For example, the recyclers have no idea on how to decide the suitability of an automotive part to be remanufactured. This study aims to develop a vehicle recovery analysis guideline to assist those in the automotive industry in developing vehicles with higher remanufacturing rates during the product development stage. In this study, there are three main criteria, and 11 sub-criteria were determined from the literatures that influences the vehicle part remanufacturing rate. These criteria are classified into three main categories namely: selection of material, method of joining, and mechanical design. Next, quantitative approach namely Analytic Hierarchy Process (AHP) methodology was applied to collect the pairwise comparison data from the automotive industry practitioners. The gathered data were analyzed using Expert Choice V11 software to determine the criteria priority weightage to influence the remanufacturing activities.

The Effect of Design Parameters on Mechanical Characteristics of Porous CoCrMo Scaffold Manufactured by Additive Manufacturing
type: item
description: Metallic orthopedic implants to replace or generate lost bones caused by traumatic road traffic injuries often failed prematurely after surgery. Bone resorption caused by stress shielding of metallic implants became a main concern as it can potentially lead to bone implant failure. Metallic scaffold designed in porous structures fabricated using additive manufacturing (AM) are widely used as bone implant, since the elastic modulus of the scaffolds can easily tailored according to the bone properties, and the large surfaces are beneficial to cell in-growth. The microarchitecture of scaffold can control their mechanical and biological properties, but it is found that there is lack of systematic approach to select a cell topology with full perspective requirements of bone implant. This paper presents a systematic approach of design space mapping for two CoCrMo unit cell shapes namely square and diamond to understand the relationship between geometrical parameters with additive manufacturing limitation, mechanical and bone ingrowth requirements. The compressive response of the components was simulated by finite element analysis and the influence of design parameters on the scaffold behaviour was compared theoretically with Gibson and Ashby model. The FEA give prediction for effective elastic modulus of 3 GPa to 4.8 GPa for diamond type and range of 6 GPa to 29 GPa for square type. Experimental results showed accurate prediction of compression elastic modulus with average error of 13% for diamond type and 35% for square type respectively. The significance of the methodology and the results showed that different design parameters of the structures can play a major role in the mechanical behaviour of the metallic scaffold.
