As imaging devices move closer to the objects under observation, it becomes increasingly difficult to reconstruct their entire three-dimensional shape. A limited number of current endoscopes and microscopes can address this problem and most of them are based on stereo vision reconstruction or comple.....

Background:Stirling cycle-based cryocoolers employ mechanical compressors activated by inductive electrical motors producing an oscillating pressure in a gas. The main disadvantage of these conventional compressors is their limited lifetime, caused by mechanical friction and wear. Wear products degr.....

Power generation from hydrogen fuel cells is a well-known environmentally-friendly and efficient method for power generation. However, as with any fuel source, hydrogen must be either produced in situ or distributed through an established distribution network. For hydrogen, distribution involves cos.....

Background:In low Reynold's number conditions, as in small scales or highly viscous environments, the dynamics are governed mainly by drag effects, therefore mechanisms must rely on non-inertial, non-time reversible trajectories. These conditions are fully satisfied by travelling mechanical waves, o.....
