Design, analysis, implementation, and control of a mobile robotic testbed for telepresence
A unique mobile telepresence testbed has been designed and implemented. This testbed is a tool for research in telepresence and tele-existence for control of remote robotic systems. An eight-degree-of-freedom, redundant ...
Thin film lithium niobate optical waveguides for integrated optics
Highly oriented polycrystalline thin films of lithium niobate on (012), (100), and (110) sapphire single crystal substrates, (111) silicon and SiO$\sb2$/(100)Si wafers were grown by magnetron rf sputtering and metallo-organic ...
FT-ICR studies of gallium arsenide cluster ions
Gallium arsenide clusters have been studied on a Fourier transform ion cyclotron resonance(FT-ICR) mass spectrometer with an external supersonic cluster source. Reaction of GaAs cluster cations with ammonia revealed that ...
