The mechanical structure of a single actuated bio-mimetic robotic fish was designed based on forced vibration responses of a non-prismatic cantilever which mimicked the fish body deformation. To realize the cruising turning and burst-and-coast moving modes the hardware system based on the micro controller unit STM32F103C8T6 and the control were developed. The state variable feedback method and PID method were used to design the control algorithms respectively. The simulation and experimental results showed that the whole system could imitate the swimming of the real fish. 2012 IEEE.

A two-step energy transfer was observed in Pr3+ and Cr 3+ codoped SrAl12O19 phosphor which results in a two-photon luminescence for one UV/vacuum-UV photon absorbed. For one Pr 3+ ion excited to the lowest 4f5d states two Cr3+ ions may be excited and emit two red photons due to 2E- 4A2 transitions of the Cr3+ ions Cr 3+ ions can be excited into the 4T1(F) levels by cross relaxation of Pr3+ 1S0- 1I6 or by direct energy transfer from Pr3+ 3P0 1 states. The mechanisms of the two-step energy transfer process were studied based on spectra and lifetime measurements. copyright The Electrochemical Society.

A new glass of Lu2O3-B2O 3-SiO2-Na2O-Er2O3 system is prepared by the technique of high-temperature melting at different temperatures and the formation range of the glass is experimentally obtained. Effects of the B2O3 content on the infrared spectral properties such as the 1.5 m emission bandwidth corresponding to 4I13/2&rarr4I15/2 transition and the Judd-Ofelt parameter t (t = 2 4 6) of Er3+ ions in the glass has been observed. The glass exhibits big integrated emission cross sections for the 1.5 m emission band. Excellent thermal stability of the glass has been demonstrated using differential thermal analysis. The Er 3+-doped lutetium borosilicate glass is a great candidate for broadband erbium doped fiber amplifiers.
