Structured programming

(Software Engineering) a design method that limited design constructs to only three basic forms and constrains program flow for better quality

Influent

(Environmental Engineering) The fluid entering a system, process, tank, etc. An effluent from one process can be an influent to another process. See effluent.

Bed-In

(english) Method whereby drag may be rammed in the pit or flask without necessity of rolling over. Process used in production of heavy castings.

Band Saw Steel (Wood)

(english) A hardened tempered bright polished high carbon cold rolled spring steel strip produced especially for use in the manufacture of band saws for sawing wood, non ferrous metals, and plastics. Usually carries some nickel and with a Rockwell value of approximately C40/45.

Blast Furnace

(english) 1) A furnace in which solid fuel (limestone, coke, iron ore) is combined with high-pressure, hot air blast (120,000 psi) to smelt ore in a continuous process (They are never stopped. They can be slowed down or idled). A Blast Furnace in the iron and steel industry is used to produce liquid iron.

Moist Room

(Concrete Engineering) A room used for storing and curing cementitious test specimens. The atmosphere of this room is maintained at a temperature of 73.4 3.0'F or 23.0*1.7'0 and relative humidity of at least 98 percent. These facilities must be adequate to continually maintain free moisture on the exteriors of test specimens.

Kelly Ball

(Concrete Engineering) A device for determining the consistency of fresh concrete. It is sometimes used as an alternative to the slump test.

Bush-hammer

(Concrete Engineering) A tool having a serrated face, as rows of pyramidal points, used to develop an architectural finish for concrete surfaces.

Nonpoint source pollution (NPSP)

(Environmental Engineering) Any pollution from a source which cannot be attributed to a particular discharge point, e.g. from agricultural crops, city streets, construction sites, etc.

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.

Vaporproof

(Concrete Engineering) A material that is totally immune to the passage of a gas under pressure. Any material that is truly vaporproof will inherently be waterproof.

Quality function deployment (QFD)

(Software Engineering) a technique that translates the needs of a customer in technical requirements for software by assessing the value of each requirement
