EPANET's computational engine is available for download as a separate dynamic link library for incorporation into other applications. [7] The source code for EPANET 2 is available on the EPA's EPANET website. [8] In 2012, Baseform released a rewrite of the EPANET toolkit in Java under the GNU GPLv3 license. [9]
The base load [2] (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants [ 3 ] or dispatchable generation , [ 4 ] depending on which approach has the best mix of cost, availability and reliability in any particular market.
A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. [1] Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost ...
In the OSI model of computer networking, a frame is the protocol data unit at the data link layer. Frames are the result of the final layer of encapsulation before the data is transmitted over the physical layer. [1] A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet."
At 1 GHz the resistivity has increased to 0.1 ohm per inch. [9] Termination and ringing: Wires longer than about 1/6 wavelengths must be modeled as transmission lines with termination taken into account. Unless this is done, reflected signals will travel back and forth across the wire, positively or negatively interfering with the information ...
As the number of flights air traffic controllers must handle is steadily increasing (for instance, Shanwick handled 414,570 flights in 2007, an increase of 5% - or 22,000 flights - from 2006 [1]), the number of pilots tuned to a particular station also increases. This increases the chances that one pilot will accidentally override another, thus ...
Just as the shannon describes the maximum possible information capacity of a binary symbol, the hartley describes the information that can be contained in a 10-ary symbol, that is, a digit value in the range 0 to 9 when the a priori probability of each value is 1 / 10 . The conversion factor quoted above is given by log 10 (2).
The theory of the least objectionable program (LOP) is a mediological theory explaining television audience behavior. [1] It was developed in the 1960s by then executive of audience measurement at NBC , Paul L. Klein , [ 2 ] [ 3 ] who was greatly influenced by the media theorist Marshall McLuhan 's Understanding Media .
