Oil and gas facilities operate under demanding conditions where equipment failures can significantly affect production availability, operational safety, and lifecycle costs. Conventional Reliability-Centered Maintenance (RCM) methodologies provide a structured framework for maintenance decision-making; however, their implementation remains largely qualitative and highly dependent on expert judgement. This study proposes an integrated Reliability-Centered Maintenance (RCM) optimization framework ...

The disassembly and assembly of marine oil-separators is a core experiment in marine engineering. To overcome the limitations of traditional physical disassembly and hands-on training, this study employs the implicit three-dimensional (3D) reconstruction theory. By utilizing a large dataset of high-definition images captured from specific angles and leveraging the Laplacian operator-based deep neural network Neural-Radiance-Field algorithm, high-precision 3D models of the oil separator body and ...

Evaporation is a critical process in the concentration of orange juice, affecting product quality and process efficiency. This study develops a comprehensive mathematical model based on mass and energy balances to simulate the influence of input process variables on the properties of orange juice concentrate in single-effect and triple-effect evaporators. The nonlinear system of equations is solved using the Newton-Raphson iterative method, with simulations conducted in MS Excel. Results demonst...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor. DC motors are widely utilized in various applications due to their simplicity and efficiency; however, robotics and automation are only performed effectively through proper control of the operational parameters. This research aims to develop a strong motor control system that can dynamically chang...

False alarm rate of artificial radioactive aerosol continuous monitor is inevitable. When the standard deviation of artificial radioactive aerosol concentration is determined, the minimum detection limit and false alarm rate are a pair of contradictory relations. This paper proposes the concept of alarm measure, transforms the results obtained by several deduction algorithms into alarm measure, and then uses DS evidence theory to fuse several alarm measures. The fused results are used as the bas...

This paper investigates the influence of ultraviolet (UV) lighting configurations on the automatic detection of Regions of Interest (ROIs) and the visual identification of surface defects in cast metal parts. A meticulous experimental setup was devised employing four UV light bars arranged in a rectangle, with varying combinations of active light sources. The study utilized the OpenCV library to automate the detection of mounting holes (ROIs) on the cast metal parts. Additionally, a visual inspe...

The severity of the ozone layer destruction problem has called for rapid developments in environmentally friendly air conditioning technologies. Ongoing deregulatory efforts in the Organization for Economic Co-operation and Development (OECD) nations will ease the penetration of thermally activated heat pump systems. Absorption (liquid-vapor) and adsorption (solid-vapor) heat pump systems are thermally driven and have the advantage of being environmentally benign: both their ODP (Ozone Depletion...

Fashion design, as the name suggests, is an industry of designing fashion styles. Conventional clothing design and production take real human beings as the carrier. With the development of subculture, the words “doll circle”, “doll mother” and “doll clothes” have gradually come into the daily life of more and more people, and the word “doll” here does not refer to human children, but refers to dolls such as Barbie dolls. “Doll mother” is the name of the doll-raising group, and “doll clothes” is ...

The vehicle-borne radiation environmental monitoring system is not restricted by time, location and weather, and in the event of a sudden nuclear accident, it can quickly enter the accident site and monitor the ambient reflectivity level and absorbed air dose rate at the first time. At the same time, the vehicle-borne data communication and processing system is used to transmit the real-time data to the platform of emergency monitoring and dispatching, which provides powerful technical support f...

Efforts have been made by some researchers to determine machines' economic performance, some considered engineering features, some supply conditions while some look into the productivity as well as profitability of the machine separately. Recently, [1] saw the performance assessment of machine as surrogate problem and they deviate from single strategic decision common in past researches to multi-criteria approach in their research. Considerations were given to: annual operation cost, machine eff...
