determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

Electrochemical behavior of thin-film Sm-doped ceria: insights from the point-contact configuration.

The electrochemical behavior of chemical vapor deposition (CVD) grown porous films of Sm-doped ceria (SDC) for hydrogen oxidation has been evaluated by impedance spectroscopy using a point contact geometry at a temperature of 650 °C. Porous SDC films, 950 nm in thickness, were deposited on both sides of single-crystal YSZ(100). Pt paste was applied over the surface of one SDC layer to create a ...

Optimization of ionic conductivity in doped ceria.

Oxides with the cubic fluorite structure, e.g., ceria (CeO2), are known to be good solid electrolytes when they are doped with cations of lower valence than the host cations. The high ionic conductivity of doped ceria makes it an attractive electrolyte for solid oxide fuel cells, whose prospects as an environmentally friendly power source are very promising. In these electrolytes, the current i...

A study of gadolinia-doped ceria electrolyte by electrochemical impedance spectroscopy

Samples of Gd2O3-doped CeO2 (GDC) were fabricated by sintering of powder compacts. Impedance spectra were measured from 400 C to 675 C in air by electrochemical impedance spectroscopy (EIS). Above w500 C, high frequency arc was not semicircular but could be fitted with a constant phase element (CPE). Abovew625 C, high frequency arc could not be resolved due to a significant contribution from th...

Optimizing ionic conductivity in doped ceria

David Andersson et al. report calculations revealing how doped oxides with cubic fluorite structures become effective ionic conductors. Cubic fluorite structures, such as ceria (CeO2), can become effective ionic conductors when doped with cations of lesser valence than the host cations. Doped ceria thus has potential as an electrolyte for environmentally friendly solid oxide fuel cells. Anderss...
