The word rate is used in two ways within the structure. First, rate is a paygrade. Enlisted navy personnel do not have rank: only naval officers do. Second, rate is an abbreviation that contains both the rating and the paygrade abbreviations.he first steamship, mine, radar, torpedo, aircraft carrier, and many other âfirstsâ all established a new era in the Navy, and each directly impacted the enlisted occupation structure. During World War II, the Navy also briefly maintained a rating of Specialist, similar to the rank in the United States Army.
In mathematics and statistics, a stationary process (or strict(ly) stationary process or strong(ly) stationary process) is a stochastic process whose joint probability distribution does not change when shifted in time.
Two opposing waves combine to form a standing wave. In physics, a standing wave â also known as a stationary wave â is a wave in a medium in which each point on the axis of the wave has an associated constant amplitude.The locations at which the amplitude is minimum are called nodes, and the locations where the amplitude is maximum are called antinodes.he length of the string then becomes a measure of which waves the string will entertain: the longest wavelength is called the fundamental. Half a wavelength of the fundamental fits on the string. Shorter wavelengths also can be supported as long as multiples of half a wavelength fit on the string.
