| Beryllium Copper | (english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc. |
| Bismuth | (english) Chemical symbol Bi. A soft, course cystalline heavy metal with a silvery white color and pinkish tinge; usually produced as a by-product of copper,leaad and other metals. Has a thermal conductivity lower than all other metals except mercury. Used as alloying agent but leading use is in pharmaceuticals. |
| Beta testing - | (Software Engineering) testing that is conducted by the user |
| Formal technical reviews - | (Software Engineering) a structured meeting conducted by software engineering with the intent of uncovering errors in some deliverable or work product |
| High-order tests - | (Software Engineering) black-box tests conducted once the software has been integrated |
| Refactoring - | (Software Engineering) changing software in a way that improves its internal structure but does not change it external behavior; often conducted iteratively as design evolves into code. |
| Regression testing - | (Software Engineering) tests that are conducted repeated to ensure that a change has not introduced side effects |
| Scheduling - | (Software Engineering) the activity that lays out a timeline for work to be conducted on a project |
| Software testing - | (Software Engineering) a set of activities conducted with the intent of finding errors in software |
