His real-world test on fast gravel roads and bumpy forest trails has found that the difference between 30 and 40psi is a 23.8 to 27.7% reduction in vibrations at the handlebar. To put this into context, Krzysztof tested a Lauf suspension fork and found it reduced vibrations by only 1.3% ...
Electromagnetic, piezoelectric, electrostatic, dielectric, and triboelectric are common energy conversion methods to harvest energy from flow-induced vibration (FIV) mechanisms. These mechanisms are generated due to the interaction between the surrounding fluid flow and the energy harvester, and they can ...
The LLCD was a project undertaken by MIT Lincoln Laboratory, NASA's Goddard Space Flight Center, and the Jet Propulsion Laboratory. It was NASA’s first attempt to demonstrate optical communications between a lunar orbiting spacecraft and Earth-based ground receivers. All prior com...
The chemical methods have been focused on the reduction of the friction factor between drill strings and wellbores [7]. The properties of the mud cake were modified or lubricants were added into the drilling fluid [8]. However, the additives of the lubricants were subject to environmental ...
