To a linear array

The Fischer device was a slot-scanning system in which a 14-mm wide fan-beam scanned across the breast over about 5 s. The image was collected by a rectangular detector consisting of a Csl crystal coupled via a fiber-optic bundle to a linear array of charge-coupled... [Pg.149]

A linear array of photodiodes providing the ability to detect simultaneously radiation at several wavelengths. [Pg.379]

Feedback Shift Registers Feedback shift registers are essentially one-dimensional finite state machines consisting of a linear array of sites i = 1,2. .., n, with each site i carrying value (7. At each time step, the system evolves according to the following... [Pg.45]

Active matrix addressing can also be used in printer heads [628] and linear sensor arrays [629]. a-Si H TFTs are used to address a linear array of output or input transducers, respectively. In the linear sensor array, u-Si H photodiodes are used. [Pg.179]

For an estimate of the ultimate shear strength, r0, of a single domain based on the lattice parameters we use a simple shear plane system proposed by Frenkel [19]. As shown in Fig. 19 it consists of a linear array of periodic force centres resembling the polymer chain. According to this model the relation between the relative displacement x along the shear direction and the shear stress is given by... [Pg.38]

As for the structures of ammonium compounds apparently no certainty has been attained. Bode and Foss followed the views of earlier authors and accepted the (NH4)sFeF6-type 245) with a linear array of ions as an example of the ideal cryolite structure. The discrepancy between the observed lattice constants and the ionic radii sum is indeed smaller in the case of ammonium-compounds. But this applies also to the compound (NH4)3GaFe, of which a structure analysis has been performed recently by Schwarzmann 303). After a detailed discussion of the possibilities of arranging the fluoride ions in this compound, Schwarzmann shows, that there must be either micro-twinning in the space group Pa3 or a statistic occupation of the 192-fold position of space group FmSw by 24 fluoride ions, as characteristic of the KsFeFs-type. [Pg.23]
