  2. Concatenated error correction code - Wikipedia

    en.wikipedia.org/wiki/Concatenated_error...

    A natural concept for a decoding algorithm for concatenated codes is to first decode the inner code and then the outer code. For the algorithm to be practical it must be polynomial-time in the final block length. Consider that there is a polynomial-time unique decoding algorithm for the outer code.

    en.wikipedia.org/wiki/List_of_HTTP_status_codes

    The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. [2] All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two digits do not have any classifying or categorization role.

  6. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    A low code-rate close to zero implies a strong code that uses many redundant bits to achieve a good performance, while a large code-rate close to 1 implies a weak code. The redundant bits that protect the information have to be transferred using the same communication resources that they are trying to protect.

  7. Reactive armour - Wikipedia

    en.wikipedia.org/wiki/Reactive_armour

    The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.

    Two versions of the vest are available, known as the "land" and "maritime" versions. The vest consists of front and rear panels with pockets for BALCS or SPEAR-cut soft armor panels and standard-issue SAPI (Small Arms Protective Insert) plates. This gives the wearer up to NIJ Level IV protection on the front and back and Level IIIA protection ...
