In mathematics, a matrix is a rectangular array of numbers, symbols, or expressions. The individual items in a matrix are called its elements or entries. An example of a matrix with six elements is Matrices of the same size can be added or subtracted element by element. The rule for matrix multiplication is more complicated, and two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. Wikipedia.

An external weld bead removal system for removing and chopping an external weld bead from a tube includes a weld bead cutting apparatus and a weld bead chopper apparatus for chopping the removed external weld bead. The weld bead cutting apparatus includes a cutting tool operative to cut and remove an external weld bead from a tube. The weld bead chopper apparatus, the weld bead chopper apparatus includes a first blade member, a second blade member mounted adjacent the first blade member, and a chopper actuator operable to forcibly rotate the first blade member about a rotation axis relative to the second blade member such that the first and second blade members cooperatively cut the removed external weld bead into smaller weld bead segments as the removed external weld bead is advanced through the chopper apparatus.

Provided are a rapid antimicrobial susceptibility test, based on an analysis of changes in morphology and growth pattern of a microbial cell under different concentrations of various antimicrobial agents, and an automated cell image analysis system therefor. The antimicrobial susceptibility test is rapidly performed based on an analysis of changes in morphology and growth pattern of a microbial cell under different concentrations of various antimicrobial agents, and this makes it possible to obtain highly reliable test results faster by six to seven times than the standard method recommended by Clinical and Laboratory Standards Institute (CLSI).
