It is widely and frequently observed that industrial robots conducting fast motion involve serious residual vibration, the period of which varies with time. To address this time-varying residual vibration problem, this paper presents a practical solution based on a time-varying input shaping technique (TVIST). First, to suppress the time-varying vibration, a guideline for designing a practical ...

Vacuum casting (VC) of reactive polymer resins in silicone molds is one the oldest rapid tooling methods. It widely used industry for prototype and small-series production thermoset plastic parts. Despite its widespread use, scientific exploration still scarce compared to other prototyping methods, such as three-dimensional (3D) printing. Compared conventional 3D printing a wide range excellent...

Abstract The adduct of Urea and Hydrogen Peroxide (UHP), also called Carbamide Peroxide, is industrially produced as a solid source hydrogen peroxide for bleaching, disinfection, oxidation reactions. As chemical combination fuel oxidiser, UHP has explosive potential but it unclear whether could sustain detonation at small scale. In the configuration we tested, succeeded in recording self‐sustai...
