A project of the social science community to develop a standardized XML markup and representation for codebooks, the primary metadata describing social science data sets. An electronic instrument designed to record measurements (temperature, relative humidity, light intensity, on/off, open/closed, voltage, pressure, etc.) over time.
Typically they are small, battery-powered devices equipped with a microprocessor, data storage, and sensor.
Although the daguerreotype was capable of capturing fine detail, the highly polished surface had a mirror effect when viewed at an oblique angle and was easily scratched and tarnished.
In printing, dashes vary in length from the three-em (longest) to the hyphen (shortest).
In typing, a dash is made by striking the hyphen key twice in succession (--).
In descriptive cataloging, the dash is preceded and followed by a space, but when it is used in subject headings to indicate subdivision, no spaces are included ( convention of indicating accompanying material and additional versions on the catalog entry for the main item, a practice that economized on the number of catalog cards needed for items sharing basic bibliographic description.
This type of entry was eliminated in A thematic map similar to a choropleth map in the use of areal symbols (tint, shading, hatching, etc.) to represent quantitative data, but instead of mapping the data to areas that correspond to administrative or enumeration units, ancillary variables are employed to change the boundaries of the areas to better represent the areal distribution of classes of data.
Synonymous with The cylinder that exerts pressure in mechanized papermaking, smoothing the surface and creating designs such as the watermark, countermark, and the lines characteristic of laid and wove paper (see this example).
A literary award presented annually since 1974 by the Reference and User Services Association (RUSA), a division of the American Library Association (ALA), to the most outstanding reference work published during the preceding calendar year.
Compression algorithms are classified as lossless or lossy, depending on whether data is lost in compression.

By exposing the plate to light in a , a laterally reversed latent image was captured in the photosensitive layer of silver iodide that could be developed with the application of mercury vapor.
