31. There are ten quality factors , and one should consider all of them to evaluate the quality of a Rudraksha bead: 32. The material Quality Factor : B is useful because it allows for an intrinsic comparisons of possible efficiency between different materials. 33. These have the advantage of being very compact, but the low quality factor of the resonators leads to relatively poor performance. 34. Phase noise has been optimized by raising the resonator s natural frequencies ( f ) and quality factors ( Q ). 35. The quality factor of atomic clocks and some high-" Q " lasers can reach as high as 10 11 and higher. 36. Therefore, one wants to design filters that have a higher quality factor at these frequencies, and this calls for improved technology. 37. The quality factors and SPP propagation lengths were calculated using the optical data from the Al, Ag, Au and Cu films. 38. This sensitivity is inversely proportional to the quality factor ( Q-factor ) of the poles of the transfer function of the filter. 39. Q is the anelastic attenuation factor or the seismic quality factor , a measure of the energy loss as the seismic wave moves. 40. Class 1 capacitors with very low losses are specified with a dissipation factor and often with a quality factor ( Q ).
