Stiffness:

(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.

Butcher Saw Steel

(english) A hardened, tempered, and polished high carbon spring steel strip material (carbon content is generally higher than that of a material used for wood band saw applications) with a Rockwell value of roughly C47/49.

Basic Oxygen Process 2

(english) A steel making process wherein oxygen of the highest purity is blown onto the surface of a bath of molten iron contained in a basic lined and ladle shaped vessel. The melting cycle duration is extremely short with quality comparable to Open Hearth Steel.

Mixing Speed

(Concrete Engineering) Rate of mixer drum rotation or that of the paddles in a pan, open-top, or trough type mixer, when mixing a batch; expressed in revolutions per minute (rpm) or in peripheral] feet per minute of A point on the circumference at maximum diameter.

Amino acid

(Environmental Engineering) A functional group which consists of a carbon with a carboxylic acid, "-COOH" and an amine, "-NH2." These compounds are the building blocks for proteins.

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

Anoxic process

(Environmental Engineering) A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.

Equivalent

(Environmental Engineering) The mass of the compound which will produce one mole of available reacting substance. Thus, for an acid, this would be the mass of acid which will produce one mole of H+, for a base, one mole of OH-.

Object-oriented analysis (OOA)

(Software Engineering) a technique for defined classes of objects, their relationships and basic structure

Bottom Up

(english) Reversing the wrap of a coil putting the top surface on the bottom.

Mass:

(english) A property of an object measured by the degree that it resists acceleration.

Errors

(Software Engineering) a lack of conformance found before software is delivered to the customer
