dc.title: Enhancing dimensional accuracy in 3D printing: a novel software algorithm for real-time quality assessment dc.contributor.author: Bowoto, Oluwole K.; Zahedi, S. Abolfazl; Chong, Seng Kwong dc.description.abstract: Notably, despite the widespread application of 3D printing technology across diverse industries, issues like dimensional variations continue to limit its full-scale production potential. In this research, the dimensional variation between the CAD model and a 3D printed specimen by extrusion technique is investigated by a developed software algorithm. In contrast to previously employed techniques such as coordinate measuring machines, laser scanning, optical profilometry, and CT scanning, which have been highlighted in the literature, the developed software algorithm is cheap and stands out by relying on computer vision for the assessment of dimensional deviations in the printed model. The proposed software algorithm assesses the dimensional quality of 3D printed components through a comprehensive three-step methodology: preparation, measurement, and analysis. The software scrutinizes both the CAD model and the G-code-sliced model, extracting crucial dimensional data that serves as a reference for monitoring deviations during the actual 3D printing process. The software is fully tested across a diverse 3D geometry, capable of predicting real-time dimensional variances that could otherwise result in printing failures. The solution not only ensures the preservation of economic and human resources in additive manufacturing but also enhances the overall efficiency of the process. The paper concludes that the choice of the appropriate method should be contingent on the specific part type and the level of accuracy required.
dc.title: Predicting Inflow, or Leak, or Declining Energy in Conduits During Fluid Evacuation Processes Using Enclosed Angle Vector Relaxation Method dc.contributor.author: Nwankwo, Cosmas; Chong, Seng Kwong; Brown, Neil dc.description.abstract: Most of the prospecting areas used for hydrocarbon exploitation in the Niger Delta were originally virgin lands but have suffered urban encroachment such that any loss of hydrocarbon containment may lead to pollution, loss of lives, major fires, and loss of major assets. Initially, pipeline loss of containment during petroleum evacuation was mainly due to corrosion, but around the year 2000, pipeline vandalism which started as a way of protesting lack of development projects by host communities, rapidly grew into an industry for crude theft through hot tapping. The cost of crude oil theft is estimated at 拢1bln per month and it is reported that some 1000 people have died due to pipeline explosion in Nigeria within the period 2011 to 2015. The desirability for the quantity of crude escaping to the environment during any loss of containment cannot be overemphasised. First, we need to know this in other to plan emergency responds on loss containment. Also, if the loss of containment is from a flowing well, we especially need this information to plan well capping or relief well planning in support of the well capping. In some jurisdictions it is also required as a mandatory regulatory reporting requirement dc.description: Output from PhD research jointly supervised within EM&SD, CEM
dc.title: 3D printing of surface characterisation and finite element analysis improvement of PEEK-HAP-GO in bone implant dc.contributor.author: Chong, Seng Kwong; Malachi, Idowu; Oladapo, Bankole I.; Zahedi, S. A.; Omigbodun, F.T. dc.description.abstract: Research and development of polyetheretherketone (PEEK) composites with high thermal conductivities and ideal thermal stabilities have become one of the hot topics in composites. However, not all PEEK composites have the necessary characteristics adequate fracture toughness to resist forces and crack propagation, with an improved mechanical and structural properties. This research evaluates a novel computational surface characterisation and finite element analysis (FEA) of polyetheretherketone and hydroxyapatite graphene oxide (PEEK-HAP-GO) in the process of 3D printing to improve fracture toughness to resist forces and crack propagation. It also focuses on increasing the hydrophilicity, surface roughness, and coating osteoconductive of PEEK-HAP-GO for the bone implant. Compression and tensile tests were performed to investigate the mechanical properties of the PEEK-HAP-GO structure. The addition of calcium phosphate and the incorporation of porosity in PEEK-HAP-GO has been identified as an effective way to improve the osseointegration of bone-implant interfaces of PEEK-HAP-GO. The further analytical structure of the particle was performed, evaluating the surface luminance structure and the profile structure of composite material in 3D printing, analysing the profile curve of the nanostructure from the scanning electron microscope (SEM). The results of the uniaxial compression tests in new PEEK-HAP-GO biodegradable materials show good compressive strength suitable for loading applications. It shows melt-blending with bioactive nanoparticles can be used to produce bioactive nanocomposites like HAP-GO and is used to modify the surface structure of PEEK implants in order to make it more bioactive. dc.description: The file attached to this record is the author's final peer reviewed version.

dc.title: Bridging the Gaps in a Model-Based System Engineering Workflow by Encompassing Hardware-in-the-Loop Simulation dc.contributor.author: Kalawsky, R.; O'Brien, J.; Chong, Seng Kwong; Wong, Chi Biu; Jia, Haibo; Pan, Hongtao; Moore, P. dc.description.abstract: This paper discusses how gaps in a model-based system engineering (MBSE) workflow can be bridged through the use of special model transformation tools. The goal is to create an integrated workflow tool chain to facilitate integration of various subsystems and verification of the overall system performance to meet a set of desired system requirements. This paper describes an implementation in a model-based representation that encompasses real system hardware-in-the-loop (HIL) components to verify the effectiveness and capability of the development platform. Discussion is provided on the developed model transformation processes that make this possible and is explained through the application of our approach to the development of subsystems for a vehicle system. The key contributions of research include: 1) identification of a suitable model-based systems design methodology and toolset (based on IBM Rhapsody/Mathworks Simulink combination) to include HIL for system verification; 2) design and development of model transformation tools to facilitate bidirectional transformation of an IBM Rhapsody model to a Simulink model; and 3) successful mapping between platform independent models and platform-specific models involving HIL. The research outcomes show particularly promising results that are anticipated to benefit the MBSE community.
dc.title: The Architecture and Development of Multi-Role Course Design of a Web-Based Group Training System dc.contributor.author: Guo, X.; Chong, Seng Kwong; Dyson, Sue, 1960-; Picinali, Lorenzo dc.description.abstract: Due to the fast development of information technology there are new opportunities for traditional training systems. Many e-training systems are proposed and implemented, however, there is rarely any research on group based e-training system that allow people to train in a group that involves different roles. This paper proposes an architecture for a web based surgery group training system that supports multi-role group training courses. A course model based on XPDL (XML Process Definition Language) is introduced to bridge the understanding of a graphical multi-role course design and the computer application. There is also an explanation on how the multi-role courses are designed and used in applications. Finally a demonstration experiment is given.
