Commutator-operated digital caliper with visual display and card-punch capacity.
A variety of automatic and semiautomatic measuring devices with print-out, card-punch, and paper-tape capacity have been used in the analysis of lateral head radiographs, posteroanterior head radiographs, and oblique-jaw views. Such devices include the tape-printing GOAT ' the card punching GADRS-4 and GADRS5,T and the OSCAR.T These automatic measuring instruments have satisfactory readout accu...

SYMPOSIUM PROCEEDINGS 1970 The aids to easy and accurate punching are twofold. For as many programmes as practicable, proformas are prepared whcre card columns arc idcntified and the entries to be made in each group of columns corresponding to the value of a variable are clearly defined. Fig. 3 gives a typical proforma used for the closed circuit respiration chamber programme, CCRC3. Note that ...
متن کاملDirect Readout of Sediment Analyses by Settling Tube for Computer Processing.
Sediment fall-velocities measured by the Woods Hole Rapid Sediment Analyzer can now be obtained directly on punched paper tape in a form suitable for processing by a computer. This technique saves much time because it eliminates manual card punching, a step in which an operator transfers values from sediment analyses to punch cards in order to make the data acceptable tocomputers.
متن کاملEstimation of Punching Shear Capacity of Concrete Slabs Using Data Mining Techniques
Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...
