(Environmental Engineering) The cycle of elements through the biotic and abiotic environment.
(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.
(Concrete Engineering) In prestress concrete, the device used to stress the tendons.
(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.
(Environmental Engineering) (TDS) is the amount of dissolved matter in the water.
(Environmental Engineering) The production of energy by the degradation of organic compounds.
(Environmental Engineering) The consumption of oxygen by the different aquatic organisms as they oxidized materials in the aquatic environment.
(Software Engineering) the set of work tasks required to build the software; defined as part of the process model
(english) Raising a ridge on sheet metal
(Concrete Engineering) The pressure exerted by a vapor that is calculated based upon relative humidity and temperature. The higher the humidity and higher temperature, in degrees Fahrenheit, the greater the vapor pressure exerted.
(english) A structure is said to behave linearly when its the deformation response is directly proportional to the loading (i.e. doubling the load doubles the displacement response). For a material, linear means that the stress is directly proportional to the strain.
