    摘要: An energy converter unit and X-ray source system are presented. The energy converter unit comprises a multilayered crystal structure having a selected layers' arrangement comprising at least first and second of layers of at least first and second material compositions. The layers-arrangement is formed of a pattern of n1 layers of said first layer type and n2 layers of said second layer type generating a selected lattice periodicity of said layers. The lattice periodicity is selected such that said multilayered crystal structure responds to the charged particle beam of predetermined parameters by coherent emission of X-ray radiation having selected spectral content and emission direction.

    摘要: A gas sensing device, that may include a suspended gas sensing element, a frame that supports the suspended gas sensing element, and one or more traps for trapping at least one out of Siloxane and silicon dioxide. The suspended gas sensing element may include a gas reactive element that has a gas dependent temperature parameter, and a semiconductor temperature sensing element that is thermally coupled to the gas reactive element, and is configured to generate detection signals that are responsive to a temperature of the gas reactive element. The gas reactive element and the semiconductor temperature sensing element are of microscopic scale.

    摘要: A method for multidimensional scaling (MDS) of a data set comprising a plurality of data elements is provided, wherein each data element is identified by its coordinates, the method comprising the steps of: (i) applying an iterative optimization technique, such as SMACOF, a predetermined amount of times on a coordinates vector, said coordinates vector representing the coordinates of a plurality of said data elements, and obtaining a modified coordinates vector; (ii) applying a vector extrapolation technique, such as Minimal Polynomial Extrapolation (MPE) or reduced Rank Extrapolation (RRE) on said modified coordinates vector obtaining a further modified coordinates vector; and (iii) repeating steps (i) and (ii) until one or more predefined conditions are met.
