Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...
In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...
DCA was later extended as MO:DCA (Mixed Object Document Content Architecture), which added embedded data files. The original purpose of DCA was to provide a common document format that could be used across multiple IBM word processing platforms, such as the IBM PC , IBM mainframes , the Displaywriter System , and the IBM 5520 Administrative ...
People looking to save money for a big trip or financial investment may want to make plans around an "extra" paycheck in their pocket.. Employees who get paid on a biweekly basis (every other week ...
Detrended correspondence analysis (DCA) is a multivariate statistical technique widely used by ecologists to find the main factors or gradients in large, species-rich but usually sparse data matrices that typify ecological community data. DCA is frequently used to suppress artifacts inherent in most other multivariate analyses when applied to ...

Directional component analysis (DCA) [1] [2] [3] is a statistical method used in climate science for identifying representative patterns of variability in space-time data-sets such as historical climate observations, [1] weather prediction ensembles [2] or climate ensembles.
Soaking your shower head in vinegar overnight. Grandma isn't completely wrong here. However, we'd like to offer a modification to the process of cleaning your shower head with vinegar.
