Aperture Card
An aperture card is a type of punched card with a cut-out window into which a chip of microfilm is mounted. Such a card is used for archiving or for making multiple inexpensive copies of a document for ease of distribution. The card is typically punched with machine-readable metadata associated with the microfilm image, and printed across the top of the card for visual identification; it may also be punched by hand in the form of an edge-notched card. The microfilm chip is most commonly 35mm in height, and contains an optically reduced image, usually of some type of reference document, such as an engineering drawing, that is the focus of the archiving process. Machinery exists to automatically store, retrieve, sort, duplicate, create, and digitize cards with a high level of automation. Aperture cards have several advantages and disadvantages when compared to digital systems. While many aperture cards still play an important role in archiving, their role is gradually being r ...

Card Sorter
A Punched card sorter is a machine for sorting decks of punched cards. Sorting was a major activity in most facilities that processed data on punched cards using unit record equipment. The work flow of many processes required decks of cards to be put into some specific order as determined by the data punched in the cards. The same deck might be sorted differently for different processing steps. A popular family of sorters, the IBM 80 series sorters, sorted input cards into one of 13 pockets depending on the holes punched in a selected column and the sorter's settings. Basic operation The basic operation of a card sorter is to take a punched card, examine a single column, and place the card into a selected pocket. There are twelve rows on a punched card, and thirteen pockets in the sorter; one pocket is for blanks, rejects, and errors. Cards are normally passed through the sorter face down with the bottom edge ("9-edge") first. A small metal brush or optical sensor is position ...

Infographics
Infographics (a clipped compound of "information" and "graphics") are graphic visual representations of information, data, or knowledge intended to present information quickly and clearly.Doug Newsom and Jim Haynes (2004). ''Public Relations Writing: Form and Style''. p.236. They can improve cognition by utilizing graphics to enhance the human visual system's ability to see patterns and trends.Card, S. (2009). Information visualization. In A. Sears & J. A. Jacko (Eds.), Human-Computer Interaction: Design Issues, Solutions, and Applications (pp. 510-543). Boca Raton, FL: CRC Press. Similar pursuits are information visualization, data visualization, statistical graphics, information design, or information architecture. Infographics have evolved in recent years to be for mass communication, and thus are designed with fewer assumptions about the readers' knowledge base than other types of visualizations. Isotypes are an early example of infographics conveying information quick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Computing
The history of computing is longer than the history of computing hardware and modern computing technology and includes the history of methods intended for pen and paper or for chalk and slate, with or without the aid of tables. Concrete devices Digital computing is intimately tied to the representation of numbers. But long before abstractions like ''the number'' arose, there were mathematical concepts to serve the purposes of civilization. These concepts are implicit in concrete practices such as: *''One-to-one correspondence'', a rule to count ''how many'' items, e.g. on a tally stick, eventually abstracted into ''numbers''. *''Comparison to a standard'', a method for assuming ''reproducibility'' in a measurement, for example, the number of coins. *The ''3-4-5'' right triangle was a device for assuring a ''right angle'', using ropes with 12 evenly spaced knots, for example. Numbers Eventually, the concept of numbers became concrete and familiar enough for counting to arise, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archival Science
Archival science, or archival studies, is the study and theory of building and curating archives, which are collections of documents, recordings and data storage devices. To build and curate an archive, one must acquire and evaluate recorded materials, and be able to access them later. To this end, archival science seeks to improve methods for appraising, storing, preserving, and cataloging recorded materials. An archival record preserves data that is not intended to change. In order to be of value to society, archives must be trustworthy. Therefore, an archivist has a responsibility to authenticate archival materials, such as historical documents, and to ensure their reliability, integrity, and usability. Archival records must be what they claim to be; accurately represent the activity they were created for; present a coherent picture through an array of content; and be in usable condition in an accessible location. An archive curator is called an ''archivist''; the curat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universities Central Council On Admissions
Universities Central Council on Admissions (UCCA) provided a clearing house for university applications in the United Kingdom from its formation in 1961 until its merger with PCAS (Polytechnics Central Admissions System) to form UCAS in 1993. History UCCA was created in response to concerns during the 1950s that the increase in university applications was unmanageable using the systems then in place, where each student applied individually to as many institutions as they chose. This concern led to the Committee of Vice Chancellors and Principals ( CVCP) setting up an ad-hoc committee in 1957 to review the matter; this committee in its Third Report of January 1961 recommended the setting up of a central agency, which subsequently became known as UCCA. Its First and Second Reports had already made a number of recommendations aimed at harmonising admissions procedures across different universities. The name UCCA referred originally to the management board (the Central Council) over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leslie Ronald Kay
Ronald Kay (4 March 1920 – 17 May 2019) was a British University administrator who was instrumental in establishing the Universities Central Council on Admissions, and who was its chief executive until his retirement in 1985. Early life and career Ronald Kay was born in Sheffield. His father Ernest (1895-1973) was a cutler who had left school at 13 to work for the firm of George Wostenholm, where he slowly rose through the ranks to achieve the position of sales manager. His mother May (née Friskney) (1898-1946) was originally from Leicester; she taught piano. Ronald was the elder of two children; his sister Shirley (1928-1986) was nearly nine years younger. Ronald gained a scholarship to King Edward VII Grammar School, and subsequently an Edgar Allen scholarship to Sheffield University, where he read English. Graduating in 1941, he was disqualified from active service as a result of poor eyesight, and instead went to London to work for the Ministry of Shipping where h ...

WIPO
The World Intellectual Property Organization (WIPO; french: link=no, Organisation mondiale de la propriété intellectuelle (OMPI)) is one of the 15 specialized agencies of the United Nations (UN). Pursuant to the 1967 Convention Establishing the World Intellectual Property Organization, WIPO was created to promote and protect intellectual property (IP) across the world by cooperating with countries as well as international organizations. It began operations on 26 April 1970 when the convention entered into force. The current Director General is Singaporean Daren Tang, former head of the Intellectual Property Office of Singapore, who began his term on 1 October 2020. WIPO's activities include hosting forums to discuss and shape international IP rules and policies, providing global services that register and protect IP in different countries, resolving transboundary IP disputes, helping connect IP systems through uniform standards and infrastructure, and serving as a general r ...

Image Scanner
An image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop ''flatbed scanner'' where the document is placed on a glass window for scanning. ''Hand-held scanners'', where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications. Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical. Modern scanners typically use a charge-coupled device (CCD) or a contact image sensor (CIS) as the image sensor, whereas ''drum scanners'', developed earlier and still used for the highest possible image quality, use a photomultiplier tube (PMT) as the image sensor. A ''rotary scanner,'' used for high-speed docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Drawing
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component. The drawings are linked together by a master drawing or assembly drawing which gives the ''drawing numbers'' of the subsequent detailed components, quantities required, construction materials and possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, abbreviations and symbols are used for brevity and additional textual explanations may also be provided to convey the necessary information. The process of producing engineering drawings is often referred to as technical drawing or drafting (draughting). Drawings typically contain multiple views of a component, although additional ''scratch views'' ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punched Card
A punched card (also punch card or punched-card) is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery. Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. The IBM 12-row/80-column punched card format came to dominate the industry. Many early digital computers used punched cards as the primary medium for input of both computer programs and data. While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still used punched cards to record votes. They also had a significant cultural impact. History The idea of control and data storage via punched hol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that can ...
