groups IIIA and VA of Mendeleyev's periodic classification table (e.g., gallium arsenide, gallium‑aluminium arsenide, indium phosphide).
"Computing element" ("CE") (4) means the smallest computational unit that produces an arithmetic or logic result.
"Contouring control" (2) means two or more "numerically controlled" motions operating in accordance with instructions that specify the next required position and the required feed rates to that position. These feed rates are varied in relation to each other so that a desired contour is generated (Ref. ISO 2806:1994).
"Critical temperature" (1 3 6) (sometimes referred to as the transition temperature) of a specific "superconductive" material means the temperature at which the material loses all resistance to the flow of direct electrical current.
"Cryptographic activation" (5) means any technique that activates or enables cryptographic capability of an item, by means of a secure mechanism implemented by the manufacturer of the item, where this mechanism is uniquely bound to either of the following:
 (1) a single instance of the item;
 (2) one customer, for multiple instances of the item.
Technical Notes:
1. "Cryptographic activation" techniques and mechanisms may be implemented as hardware, "software" or "technology".
2. Mechanisms for "cryptographic activation" can, for example, be serial number‑based licence keys or authentication instruments such as digitally signed certificates.
"Cryptography" (5) means the discipline which embodies principles, means and methods for the transformation of data in order to hide its information content, prevent its undetected modification or prevent its unauthorised use. "Cryptography" is limited to the transformation of information using one or more 'secret parameters' (e.g., crypto variables) or associated key management.
Note 1: "Cryptography" does not include 'fixed' data compression or coding techniques.
Note 2: "Cryptography" includes decryption.
Technical Notes:
1. 'Secret parameter': a constant or key kept from the knowledge of others or shared only within a group.
2. 'Fixed': the coding or compression algorithm cannot accept externally supplied parameters (e.g., cryptographic or key variables) and cannot be modified by the user.
"CW laser" (6) means a "laser" that produces a nominally constant output energy for greater than 0.25 seconds.
"Cyber incident response" (4 ML21) is the process of exchanging necessary information on a cybersecurity incident with individuals or organisations responsible for conducting or coordinating remediation to address the cybersecurity incident.
"Data‑Based Referenced Navigation" ("DBRN") (7) Systems means systems which use various sources of previously measured geo‑mapping data integrated to provide accurate navigation information under dynamic conditions. Data sources include bathymetric maps, stellar maps, gravity maps, magnetic maps or 3‑D digital terrain maps.
"Depleted uranium" (0) means uranium depleted in the isotope 235 below that occurring in nature.
"Development" (GTN NTN All) is related to all stages prior to serial production, such as: design, design research, design analyses, design concepts,
