This paper outlines the general principles involved in designing a satisfactory sound-reinforcing system with special reference to the relative position of microphone and loudspeaker. Types of loudspeaker and microphone suitable for different situations are discussed. We consider the problem Replica Louis Vuitton of characterizing those linear operators L on Louis Vuitton Handbags Online the matrices over a semiring such that L(X) is idempotent if and only if X is. Complete characterizations are obtained for many semirings, including the nonnegative reals, the nonnegative integers, the two-element Boolean algebra, and the fuzzy scalars. The energy compression system at the Glasgow 170 MeV electron linac is described. A system of three magnets plus a radio-frequency cavity is used to compress the linac energy spectrum by a factor of 5 to 15, depending on energy. Examples of compressed spectra are shown, and the effect of a phase shift in the compression cavity is demonstrated. We study the components of the matrices that belong to the image of the Burau representation of braids, and establish both algebraic and order constraints for a given Laurent polynomial to possibly be a component of such a Burau matrix. As an application partial faithfulness results for the Burau representation are deduced.
