Abstract: The non-contact acoustic manipulation of particle clusters has great potential in various fields. However, current acoustic manipulation technologies for particle cluster manipulation ...

So, you’ve got a HackerRank test coming up, huh? It’s pretty common these days, with lots of companies using it to see if you can code. It can feel a bit daunting, but honestly, it’s just another ...

HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses, where developers compete by trying to program according to provided specifications.

Abstract: This paper presents a new type of distributed dexterous manipulator: delta arrays. Our delta array setup consists of 64 linearly-actuated delta robots with 3D-printed compliant linkages.

The partially reduced TiO(2) nanotube arrays (TNAs) are prepared via an uncomplicated and low-cost liquid phase reduction strategy using NaBH(4) as the reducing agent. By controlling and adjusting the ...

The strong gradient in the evanescent fields of these structures can trap and transport a large array of particles, even at a low optical power 9 – 12, 19 – 27. Despite recent advances, no device has ...
