The project aimed to develop and improve machine translation (MT) systems between all official languages of the European Union (EU). EuroMatrix was followed up by another project EuroMatrixPlus (March 2009 to February 2012).
The exponential of a Metzler (or quasipositive) matrix is a nonnegative matrix because of the corresponding property for the exponential of a nonnegative matrix. This is natural, once one observes that the generator matrices of continuous-time Markov chains are always Metzler matrices, and that probability distributions are always non-negative.
The European single market, also known as the European internal market or the European common market, is the single market comprising mainly the 27 member states of the European Union (EU). With certain exceptions, it also comprises Iceland , Liechtenstein , Norway (through the Agreement on the European Economic Area ), and Switzerland (through ...
A social accounting matrix (SAM) represents flows of all economic transactions that take place within an economy (regional or national). It is at the core, a matrix representation of the national accounts for a given country, but can be extended to include non-national accounting flows, and created for whole regions or area.

The Leitner system [1] [2] [3] is a widely used method of efficiently using flashcards that was proposed by the German science journalist Sebastian Leitner in 1972. [ 4 ] [ 5 ] It is a simple implementation of the principle of spaced repetition , where cards are reviewed at increasing intervals.
Hadamard's maximal determinant problem, named after Jacques Hadamard, asks for the largest determinant of a matrix with elements equal to 1 or −1. The analogous question for matrices with elements equal to 0 or 1 is equivalent since, as will be shown below, the maximal determinant of a {1,−1} matrix of size n is 2 n−1 times the maximal determinant of a {0,1} matrix of size n−1.
A MET (Materials, Energy, and Toxicity) Matrix is an analysis tool used to evaluate various environmental impacts of a product over its life cycle. The tool takes the form of a 3x3 matrix with descriptive text in each of its cells.
