Setting or clearing ("unclicking") a checkbox changes the checkbox's state with no other side-effects.Violating this guideline by associating additional actions with the change of state frequently confuses users, because they are used to configuring data in entry controls such as text boxes, radio buttons, and checkboxes and then invoking an action control such as a push button to initiate the ...
A form of spatial aliasing can also occur in antenna arrays or microphone arrays used to estimate the direction of arrival of a wave signal, as in geophysical exploration by seismic waves. Waves must be sampled more densely than two points per wavelength , or the wave arrival direction becomes ambiguous.
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. [3] They come in four main pairs of shapes, as given in the box to the right, which also gives their names, that vary between British and American English. [1] "
Web development is the work involved in developing a website for the Internet (World Wide Web) or an intranet (a private network). [1] Web development can range from developing a simple single static page of plain text to complex web applications, electronic businesses, and social network services.
A graph database (GDB) is a database that uses graph structures for semantic queries with nodes, edges, and properties to represent and store data. [1] A key concept of the system is the graph (or edge or relationship).
Some programming languages (or compilers for them) provide a built-in (primitive) or library decimal data type to represent non-repeating decimal fractions like 0.3 and −1.17 without rounding, and to do arithmetic on them.
The Lutheran Erfurter Enchiridion of 1524 contains the text with the melody, which was also used for In Gottes Nahmen fahren wir, a pilgrims' hymn. Bach wrote a four-part chorale on the hymn tune in BWV 298; he used it for the trumpet canon in the opening chorus of cantata BWV 77 ; and much later he set it for organ in the first two of the ...
Instead it is possible to maintain an array of distances between all pairs of clusters. Whenever two clusters are merged, the formula can be used to compute the distance between the merged cluster and all other clusters. Maintaining this array over the course of the clustering algorithm takes time and space O(n 2). The nearest-neighbor chain ...
