Automated estimation tools

แปลว่า(Software Engineering) tools that help in estimating project cost or effort

Nitrification

แปลว่า(Environmental Engineering) The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems. The purpose of nitrification in wastewater treatment systems is a reduction in the oxygen demand resulting from the ammonia.

ASR - Alkali-Silica Reactivity

แปลว่า(Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete.

Bed-In

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

Bent Axis Pumps

แปลว่า(english) In this pump, the pistons are at an angle to the drive shaft and Thrust Plate. The piston block shaft is connected to the drive shaft by a universal joint, not shown. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. The connecting rods are attached to the thrust plate and revolve with it, unlike the swash plate pump where the piston rods slide past a stationary swash plate. The outlet ports are semi-circular holes in the Valve Plate, shown on the far right of the animation on edge and in a head-on view below, right. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port. This pump should be compared to the radial piston pump, swash plate pump, and wobble pump.

Vector:

แปลว่า(english) A mathematical entity having a magnitude and a direction in space.

Mixed liquor volatile suspended solids (MLVSS)

แปลว่า(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.

Jacking Equipment

แปลว่า(Concrete Engineering) In prestress concrete, the device used to stress the tendons.

Blowhole

แปลว่า(english) A defect in a casting caused by trapped steam or gas.

Mixed liquor suspended solids (MLSS)

แปลว่า(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.

Total dissolved solids

แปลว่า(Environmental Engineering) (TDS) is the amount of dissolved matter in the water.

Blue Annealing

แปลว่า(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.
