Postero-anterior films of the chest frequently fall to reveal satisfactory evidence of the pathology which may be present. To obtain a better perspective of the lung lesions, it is often necessary to resort to lordotic and oblique films. The value of such positional roentgenograms, however, has been limited because the importance of definite methods of standardizing these films has not received...

Modifications in recorder standardization are required to correct inherent scalar differences among potential differences measured in a given electrocardiographic reference frame. In the frontal plane, agreement between the resultant vectors calculated from unipolar limb lead measurements and from standard lead measurements can be obtained by standardizing the galvanometer for recording the uni...

This paper describes the status of the standardization efforts of a Component Metadata approach for describing Language Resources with metadata. Different linguistic and Language & Technology communities as CLARIN, META-SHARE and NaLiDa use this component approach and see its standardization of as a matter for cooperation that has the possibility to create a large interoperable domain of joint ...

The research leading to standard measurement techniques for characterizing practical superconductors is described. Special attention is given to measuring critical current.
