| Yield stress: | (english) A material loaded beyond its yield stress, no longer exhibits linear elastic behavior. Metals, particularly mild steel, generally have a very well defined yield stress compared to other materials. Yield stress is sometimes called yield strength. |
| Yield strain: | (english) A material deformed beyond its yield strain, no longer exhibits linear elastic behavior. See yield stress. |
| Secured landfill | (Environmental Engineering) A landfill which has containment measures such as liners and a leachate collection system so that materials placed in the landfill will not migrate into the surrounding soil, air and water. |
| Thermocline | (Environmental Engineering) The depth at which an inflection point occurs in a lake temperature profile. |
| Troposphere | (Environmental Engineering) The lower atmosphere, from the earth's surface to approximately 12 km. This portion of the earth's atmosphere contains about 95 percent of the atmospheric gases. The temperature gradually declines through this region. |
| Baseline - | (Software Engineering) a point at which some deliverable produced during the software engineering process is put under formal change contro |
| Classic life cycle - | (Software Engineering) a linear, sequential approach to process modeling |
| Line-of-code metrics - | (Software Engineering) measures of quality or productivity that are normalized using lines of code produced |
| LOC - | (Software Engineering) lines of code |
| Scheduling - | (Software Engineering) the activity that lays out a timeline for work to be conducted on a project |
