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.
Stationary fronts prolong bad weather. A cold front is the boundary between cool and warm air when the cool air is replacing the warm air. A warm front is the boundary when the warm air is winning the battle. When the pushing is a standoff, the boundary is known as a stationary front. Stationary fronts often bring several days of cloudy, wet weather that can last a week or more. Since neither the warm air nor the cold air are advancing, the stationary front weather map symbols combine both the cold front and the warm front symbols. Maps show stationary fronts with alternating triangles pointing away from the cold air and half circles pointing away from the warm air. Color maps alternate the cold front blue and warm front red. A weather map's frontal position shows where the boundary touches the Earth.
