A system for performing interactive virtual reality sessions without constraining the mobility of a user is disclosed. Moreover, a method for analyzing a materials library in which the materials library is simultaneously tested using at least two methods in which electromagnetic radiation of different wavelength ranges is used. Unlike certain commercially available cyanate esters, those of the instant invention substantially maintain or even increase in strength upon addition of the filler to the system. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. Optionally, the fiber optic assembly may further include a coaxial adapter for transmitting power. Each of the anti-nodes produces cavitation in fluids in contact with the probe.
