It can be quite the hassle, trying to measure curved surfaces with either a stiff metal tape measure or a floppy cloth one that won't stay in place. The Tiroler 2.0 offers a clever alternative, and it ...

The Samsung Galaxy Z Flip 7 has appeared in a hands-on video prior to launch. The phone will become official in two days.

A novel mechanism to generate nonrevisiting uniform coverage (NUC) paths on arbitrarily shaped object surfaces is presented in this work. Given a nonplanar surface, nonzero curvature makes traditional ...

An analytical study of the electron trajectories between two opposite electrodes having curved surfaces is undertaken for the case when the electron transit time exceeds the RF period. The analysis is ...
