Under an uncertain environment, two manufacturing strategies emerged: manufacturing system automation and manufacturing system integration. Existing case studies indicate that firms should adopt manufacturing integration first and then automate the manufacturing system to improve manufacturing performance. This study empirically supports this proposition using 303 responses from manufacturing m...

Temporal fluctuations of the atmospheric piston are critical for interferometers as they determine their sensitivity. We characterize an instrumental setup, termed the piston scope, that aims at measuring the atmospheric time constant, tau(0), through the image motion in the focal plane of a Fizeau interferometer. High-resolution piston scope measurements have been obtained at the observatory o...

Interring gas dynamic analysis of piston in a diesel engine considering the thermal effect. Understanding the interaction between ring dynamics and gas transport in ring pack systems is crucial and needs to be imperatively studied. The present work features detailed interring gas dynamics of piston ring pack behavior in internal combustion engines. The model is developed for a ring pack with fo...

In this study, a tension extension spring fatigue machine was designed and manufactured. The force applied by jaws were driven pneumatic piston. air pressure is 6 bar that acquired from local network. maximum to meet at least 12 kN. Thereby, multiple quantity of springs can be tested simultaneously. adjusted adjuster. cycles controlled an electronic circuit. also complement desired number cycle...

A conceptual design of Stirling engine suitable for onboard aircraft application is the motivation behind this study. The aim to evaluate suitability system be integrated in as part energy contributor by recycling waste thermal energy. parametric evaluation an established Wobble-Yoke Engine state space model was performed determine a pre-compensator that able produce highest power output given ...

In today's competitive market, quality has an important role in manufacturing system. The manufacturers attempt to maintain their production system in a proper condition to produce high quality products. One of the key factors to achieve this goal is maintenance policy. Most studies on maintenance focused on machines and less attention has been paid to human resources as the most important fact...
