IPC: G06F17/14
Filed: 1988-12-23
Abstract: It is known to separate two-dimensional spectral transforms, which transform data from the original domain into the spectral domain, into two one-dimensional transforms. Computation of the coefficients of this spectral domain is bound up with a large number of arithmetic operations. This expense can be reduced by decomposing the transform tensor [T] into a product of derived tensors [Ti], i = 1,...,a. The initial data present in an initial matrix [X] are input line-wise into a memory S. To carry out the transform, a matrix-vector multiplication is carried out between the derived tensor [Ta] and the initial vector, and the result is written into the memory S. Using the content of the memory S, a matrix-vector multiplication is carried out only (a-1) times with the tensors [Ti], i = 1,...,a-1, results of the sth matrix-vector multiplication being written once again into the memory S, and is thus a factor of the (s + 1)th multiplication. The result vector contains the coefficients of the spectral domain. It is advantageous to apply the method for image transmission systems. <IMAGE>

Abstract: Process for superficial modification of the surface of a metal substrate containing predominantly iron by forming an alloy with at least one additive element, by means of a concentrated energy beam such as a laser beam. The invention also relates to the application of the process in the manufacture of ferrous alloys and of catalysts, and to the alloys obtained by the process. According to the process at least one treatment comprising the following stages is carried out: a) The surface of the substrate is covered with a film containing at least one salt of a carboxylic acid chosen from aliphatic and aromatic carboxylic acids and hydroxy-substituted aliphatic and aromatic carboxylic acids. This salt contains at least the element which is to form the alloy. b) The surface thus covered is irradiated with the beam, the parameters linked with this irradiation being adapted so that a substantial thickness of the immediately underlying substrate melts and so that the element originating from the decomposition of the salt and the molten part of the substrate undergo mixing. c) The alloy thus obtained is resolidified. The invention applies especially to the manufacture of metal articles which have improved surface characteristics such as resistance to wear and/or to corrosion.
