This paper presents three trajectory tracking control strategies for unicycle-type robots based on a leader-followers scheme.The leader robot converges asymptotically to a smooth trajectory, while the follower robots form an undirected open-chain configuration at the same time.It is also Spacecraft shown that the orientation angles of all the robot
In this work we investigate the triboelectric properties of Carbon Quantum Dots (CQDs) films for potential application in triboelectric generators.CQDs were deposited on silicon wafers, using spin on techniques.Device performance was estimated in sliding mode experiments, where Wooden Dollhouse Accessories the CQDs-surface was sliding on top of a f
Two groups of martensitic alloys were examined for changes induced by deep cryogenic treatment (DCT).The first group was a range of binary and ternary compositions Car Model Kit with 0.6 wt % carbon, and the second group was a commercial AISI D2 tool steel.X-ray diffraction showed that DCT made two changes to the microstructure: retained austenite
On estimations of the lower and upper bounds for the spectral and nuclear norm of a tensor, Li established neat bounds for the two norms based on regular tensor partitions, and proposed a conjecture for the same bounds to be hold based on general Crop Tee tensor partitions [Z.Li, Bounds on the spectral norm and the nuclear norm of a tensor based on
