Abstract: A droplet generator has been designed and built to make wax and tin alloy droplets for freeform fabrication. The linear stability theory of liquid jets for forming droplets is first reviewed. ...

Abstract: WeBid is a prototype web-based framework developed for supporting and facilitating early supplier involvement in new product development on the Internet. It provides a suite of rigorous and yet ...

Abstract: By viewing the topside of a weld pool, a skilled operator can estimate the weld joint penetration. The weld pool shape or the solidified bead shape is crucial for weld quality. Automatic ...

Abstract: When an elastic wave propagates through a rock mass, its amplitude is attenuated and velocity is slowed due to the presence of fractures. During wave propagation, if the shear stress at a fracture interface reaches the ...

Abstract: An enhanced approach of empirical mode decomposition based random decrement technique (EMD-RDT) is proposed for output-only modal parameter identification of structures using ambient vibration measurements. In the conventional ...

Abstract: Aerosols generated during endoscopic sinus procedures present a concern to the health and safety of healthcare personnel, especially with the presence of coronavirus disease (COVID-19). The purpose of this study is to ...

Abstract: In this work, hybrid fuels consisting of diesel fuel, tung oil, and ethanol were made. The spray characteristics and engine performance of hybrid fuels were studied utilizing a spray visualization system under atmospheric ...
