Reinforced concretereinforced concrete Concrete in which steel reinforcement is embedded in such a manner that the two materials act together in resisting forces. Also called baton arme,ferro concrete Reinforcement System of steel bars, strength or wires for absorbing stensile, shearing and sometimes the compressive stresses in a concrete member or structure Reinforcing bar Steel bar for enforcing concrete, usually specified by the number equivalent to its diameter in eight of an in...

Data point - Observation/record of (perhaps multiple) measurements for a single member of a population or data set. In the standard tabular format, a row of data. Bayesian Information criterion (BIC) - Model selection technique that trades off model fit and model complexity. When comparing models, the model with lower BIC is preferred. Generally penalizes complexity more than AIC. 1-norm (rectilinear distance, Manhattan distance) - Think of distances in blocks E (|xi - yi|) 2-norm (euclide...
