| Stepwise refinement - | (Software Engineering) a technique for accomplishing functional decomposition or procedural design (also called partitioning) |
| Task analysis - | (Software Engineering) a software engineering action that is conducted as part of user interface design; intended to better understand how a user is to interact with a system |
| Task set - | (Software Engineering) a collection fo software engineering tasks that are required to complete an activity or action that is part of a software process framework |
| Unit testing - | (Software Engineering) part of the testing strategy that focuses on tests to individual program components |
| User-story - | (Software Engineering) a usage scenario that is used as part of Extreme programming |
| Work breakdown structure (WBS) - | (Software Engineering) the set of work tasks required to build the software; defined as part of the process model |
| Absolute Volume | (Concrete Engineering) The volume of an ingredient in its solid state, without voids between individual pieces or particles, in the case of fluids, the cubic content occupied. In concrete, the actual volume occupied by the different ingredients determined by dividing the weight of each ingredient pounds, by ifs specific gravity, times the weight of one cubic foot of water in pounds. Example: Absolute Volume of one sack of cement equals: 94 ๗ (3.15X62.4) = 0.478 cubic feet |
| Absorbed Moisture | (Concrete Engineering) Moisture which is mechanically held in a material. In aggregates, that water which is not available to become part of the mixing water is designated "absorbed" water. |
| Air Content | (Concrete Engineering) The amount of entrained or entrapped air in concrete or mortar, exclusive of pore space in aggregate particles, usually expressed as a percentage of total volume of concrete or mortar. |
| ASR - Alkali-Silica Reactivity | (Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete. |
