| Line-of-code metrics - | (Software Engineering) measures of quality or productivity that are normalized using lines of code produced |
| Patterns - | (Software Engineering) a stylized description or characterization of a software problem or capability and/or the manner in which a solution to the problem or capability may be characterized, applied, and implemented |
| Project size - | (Software Engineering) an indication of the overall effort to be expended or the number of people working on the project |
| Software engineering - | (Software Engineering) a discipline that encompasses the process associated with software development, the methods used to analyze, design and test computer software, the management techniques associated with the control and monitoring of software projects and the tools used to support process, methods, and techniques. |
| Software process improvement (SPI) - | (Software Engineering) a set of software engineering activities that attempt to improve the state of software engineering practice within an organization |
| Software quality assurance (SQA) - | (Software Engineering) a series of activities that assist an organization in producing high quality software |
| Software safety - | (Software Engineering) an SQA activity that focuses on the identification and assessment of potential hazard that may have a negative impact on the operation of software |
| Unified process - | (Software Engineering) a "use-case driven, architecture-centric, iterative and incremental" software process that emphasizes the use of UML notation |
| AAC - Autoclaved Aerated Concrete | (Concrete Engineering) Exceptionally lightweight precast concrete with high thermal qualities and fire resistence. Suitable for cutting with ordinary hand tools. Mix design is composed of portland cement, sand or siliceous material, lime, gypsum, finely powdered aluminum, and water. Initial mix is a combination of portland cement, sand, lime and gypsum to produce a slurry. Finely powdered aluminum mixed into a paste is added prior to placement into large, rail-like forms. The finely powdered aluminum reacts with the alkaline components of the cement and lime to produce hydrogen gas, which increases the volume approximately five times producing a uniformly, dispersed cellular structure. Units are cut to required shape. Units are placed in an autoclave, an enclosed pressurized chamber, and steam cured at 3500 F. Approximately 80% of the ultimate volume consists of air voids. |
| Blaine Fineness | (Concrete Engineering) The fineness of granular materials such as cement and pozzolan, expressed as total surface area in square centimeters per gram, determined by the Blaine air-permeability apparatus and procedure. |
