Dry flattening the paper of a print can sometimes remove signs of cockling, creasing, or wrinkling, In this process, the print is laid flat on a surface, and the weight of another object is used to add even pressure across the print. Sometimes flattening can be unnecessary, such as when storing items in a folder may be suitable instead. [8]
There are several explanations of why the yield curve becomes inverted. The "expectations theory" holds that long-term rates depicted in the yield curve are a reflection of expected future short-term rates, [9] which in turn reflect expectations about future economic conditions and monetary policy. In this view, an inverted yield curve implies ...
PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2.
Flattening is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution respectively. Other terms used are ellipticity , or oblateness . The usual notation for flattening is f {\displaystyle f} and its definition in terms of the semi-axes a {\displaystyle a} and b {\displaystyle b} of ...
Foxing is an age-related process of deterioration that causes spots and browning on old paper documents such as books, postage stamps, old paper money and certificates. The name may be a variant form of the English West country dialect term foust and Scots foze , to become moldy. [ 1 ]
It does however make difference, whether the photograph is taken landscape or portrait. A 50 mm lens is suitable for photographing people when the orientation is landscape. Conversely, using lenses with much longer focal lengths for portraits results in more extreme flattening of facial features, which also may be objectionable to the viewer. [2]
PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document ...
The damage on the metal sheet or characteristic pattern illustrates an "uneven surface," a change in the sheet material's plastic behavior and involves a larger deformed volume compared to mere flattening of the surface oxides. Galling is a form of wear caused by adhesion between sliding surfaces.
