This study aims to conduct a comprehensive review on the implementation of quality management practices (QMP) and their implications of organizational performance in the oil and gas sector. Quality management is crucial in such a complex and high-stakes sector where even minor errors can have significant consequences. The paper systematically reviews quality management practices, emphasizing their advantages and critical factors that impact organizational performance. The findings highlight two key insights: firstly, although QMP demonstrate a positive influence on organizational performance, their adoption within the oil and gas sector remains relatively limited. Secondly, there is a notable scarcity of research focusing specifically on quality management practices within this industry. By addressing these gaps, this review contributes to a deeper understanding of QMP's role in enhancing organizational performance within the oil and gas sector.

Optimising F1 in Schools Car Design Using CFD Simulation and Wind Tunnel Testing for Enhanced Aerodynamic Performance

Sat, 30 Mar 2024 00:00:00 +0800

F1 in Schools, a STEM competition for students, fosters collaborative design and manufacturing of the fastest miniature cars inspired by Formula 1 racing. To achieve the fastest car, the design must be optimised to reduce drag as much as possible. This paper focuses on optimising drag force, a key determinant of speed and stability. Through CFD simulations, various design iterations were evaluated. Each change was made based on targeting airflow obstructions and flow separation. A wind tunnel experiment was conducted to verify the results obtained through CFD. Results show that modifications significantly reduced drag force by 9.89%. Insights from this study underscore the importance of iterative design processes. Further enhancements could involve analysing pressure distribution and lift force to maximise thrust utilisation and improve race performance.

Interest in hydrogen economy is developing rapidly and spearheaded by developed countries to mitigate the combined effects of volatile fossil fuel market and environmental pollution. The transportation sector is a key area in the transition from fossil-based fuels to a clean hydrogen fuel. Fuel cell electric vehicle (FCEV) technology have matured and successfully tested on a wide range of transportation platforms. To enable FCEV as commercially viable, an important factor is the availability of hydrogen refuelling stations (HRS) at fuel costs that is affordable. This article explores the expansion of HRS designs and operation based on the emphasis on green energy concepts towards achieving improvements in the Levelized Cost of Hydrogen (LCOH). It is acknowledged that the success of a green HRS operation in meeting targeted LCOH is highly dependent on the cost of the energy source, where solar and wind power are the current central solutions. LCOH are seeing a visible reduction as new cost-effective technologies emerge, as well as greater emphasis are given on optimizing the operation. The review concluded that green HRS is capable of meeting a commercially attractive LCOH within five to ten years mainly through the optimization of operation strategy.

Analysis of 3D Printing Filament Using Polyvinyl Alcohol (PVA)

Sat, 30 Mar 2024 00:00:00 +0800

The widespread adoption of 3D printing as a manufacturing method across various industries offers a diverse range of filaments tailored to specific printing requirements. However, the production of intricate designs presents challenges, particularly in the removal of support structures. This research explores the manual removal and aqueous dissolution times, evaluating resultant model quality. Categorizing eighteen samples into simple, medium, and complex groups, each comprising three units forms the basis for assessing Polyvinyl Alcohol (PVA) filament’s impact on support structures and overall model quality. Nine samples exclusively use Polylactic Acid (PLA) as a control group, while the remaining nine integrate PVA filament, ensuring a comprehensive examination of PVA's influence on different design complexities. For meticulous design, Autodesk TinkerCAD meticulously guides the design process with precision, utilizing two 3D printers: the Creality Ender 3, exclusively using PLA filament, and the Ultimaker 3 Extended, equipped with dual print cores and utilizing both PLA and PVA filaments. The inclusion of PVA as a support material proves pivotal in facilitating the printing of intricate designs due to its facile removal and environmentally friendly properties. The PVA is better at support compare to PLA with lesser damage. This study significantly contributes to optimizing 3D printing processes, addressing challenges related to intricate designs and support structure removal. The findings are relevant for industries relying on precise components through 3D printing, marking a stride towards enhanced manufacturing efficiency.

Effect of the Recycled Polypropylene Fibers on the Physical and Mechanical Properties of Unreinforced Concrete

Tue, 30 Apr 2024 00:00:00 +0800

Polypropylene (PP) is widely used in the construction industry to produce a variety of materials. Accordingly, a huge amount of waste is produced during or after the construction activity. The PP fiber provide a good alternative solution to enhance concrete properties and more sustainable concrete produced in term of isolation and weight reduction. In this study, 24 concrete cubic samples are cast adding different PP fiber content to characterize this fiber effect on concrete physical and mechanical characteristics. The results demonstrate that using higher fiber content reduced the mass of concrete extensively. However, at higher PP fiber content the unconfined compressive strength decreased compared to the controlled samples. The outcomes imply that using PP fiber contributes to the protection of environment by reducing the quantity of PP waste from construction materials.
