(english) A mathematical entity having a magnitude and a direction in space.
(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.
(Concrete Engineering) In prestress concrete, the device used to stress the tendons.
(english) A defect in a casting caused by trapped steam or gas.
(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.
(Environmental Engineering) (TDS) is the amount of dissolved matter in the water.
(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.
(Software Engineering) oriented methods that categorizes elements of the problem
(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.
(english) The energy stored in a raised object (e.g. the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.
(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
(Software Engineering) when a defect is introduced early in the software process and remains undetected, it often is amplified into multiple defects later in the software process
