A slot is a narrow opening for receiving something, such as a coin or letter. It may also refer to a position or assignment. The word slot has been in use since the mid-15th century. In gambling, the term is most often used to describe a machine that pays out winning combinations according to a predetermined formula. Modern slot machines are controlled by microprocessors, and each symbol has a distinct probability of appearing on each reel. These odds are weighted to give certain symbols a higher chance of being seen than others, although the actual frequency with which each symbol appears on the physical reel is still determined by chance.
A specialized table slot, the periodic slot is used to hold data that repeats at a regular time interval. For example, a set of monthly evaporation coefficients for a reservoir would be stored in a periodic slot, which could have either text or numeric column headings. Periodic slots can have a variety of timeseries specifications (1 Hour, 1 Day, 1 Month, etc) and can also be configured to lookup or interpolate.
Expression slots use the RiverWare Policy Language (RPL), the same language in which RiverWare rules are written. The RPL syntax allows the user to define simple expressions or complex logic and functions. The values in an expression slot are solved for and evaluated in the same manner as other variables in the model. For example, if a variable has units specified, the resulting values in the slot will have the same unit type as the other variables in the simulation.
Using the File menu, you can select the Show Selection Statistics option to display information on the selected slot. This displays a list of the values solved for or set in the slot along with some statistical information on these values, including the sum, average, median, min, max, range, and difference.
Slots are found throughout the casino, and they are usually located near the center or on the edges of the game area. They are marked with a large, distinctive icon and have their own Slot Viewer. Some slot types, such as the expression and Series Slots with Periodic Input slots, have additional configuration options and open in a different Slot Viewer.
In the case of the latter, there is special ornamentation in the column heading to indicate that the slot has periodic input. To edit these slots, click on the icon in the Slot Viewer to open the corresponding Slot Dialog.
The z receiver is a good position for quick guys or shifty players because they can’t be grabbed instantly by the cornerbacks. They can stand off the line a few feet and gain 8-15 yards. This is a great spot for the TE too because he can make the defenders miss, and then go for a longer gain.
