[1]: §21.3.2 302 Moved Temporarily The client should try at the address in the Contact field. If an Expires field is present, the client may cache the result for that period of time. [1]: §21.3.3 305 Use Proxy The Contact field details a proxy that must be used to access the requested destination. [1]: §21.3.4 380 Alternative Service
Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.
As the HTTP/1.0 standard did not define any 1xx status codes, servers must not [note 1] send a 1xx response to an HTTP/1.0 compliant client except under experimental conditions. 100 Continue The server has received the request headers and the client should proceed to send the request body (in the case of a request for which a body needs to be ...
In predictive analytics, a table of confusion (sometimes also called a confusion matrix) is a table with two rows and two columns that reports the number of true positives, false negatives, false positives, and true negatives. This allows more detailed analysis than simply observing the proportion of correct classifications (accuracy).
Since [7, 4, 3] = [n, k, d] = [2 m − 1, 2 m − 1 − m, 3]. The parity-check matrix H of a Hamming code is constructed by listing all columns of length m that are pair-wise independent. Thus H is a matrix whose left side is all of the nonzero n -tuples where order of the n -tuples in the columns of matrix does not matter.
Patterns are: all ones, 1:7, 2 in 8, 3 in 24, and QRSS. T1-DALY and 55 OCTET - Each of these patterns contain fifty-five (55), eight bit octets of data in a sequence that changes rapidly between low and high density. These patterns are used primarily to stress the ALBO and equalizer circuitry but they will also stress timing recovery. 55 OCTET ...
