Canadian Journey Series
Canadian Journey is the sixth series of banknotes of the Canadian dollar designed and circulated by the Bank of Canada. It succeeded the 1986 Birds of Canada banknote series. The first banknote of the Canadian Journey series issued into circulation was the $10 bill on 17 January 2001, and the last to be issued was the $50 bill on 17 November 2004. The series was succeeded by the 2011 Frontier Series, the banknotes of which were first issued into circulation from 2011 to 2013. This series introduced new security features and discontinued the use oplanchettes a security feature common since the earliest Canadian banknote series. All banknotes have tactile features to assist people who have visual impairments to identify the notes. Designs on the reverse of each banknote in the series were based on themes of fundamental Canadian values and achievements. The $20 banknote was awarded 2004 Banknote of the Year by the International Bank Note Society. Design The Bank of Canada began ...

Canadian Bills2
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focus Group
A focus group is a group interview involving a small number of demographically similar people or participants who have other common traits/experiences. Their reactions to specific researcher/evaluator-posed questions are studied. Focus groups are used in market research to understand better people's reactions to products or services or participants' perceptions of shared experiences. The discussions can be guided or open. In market research, focus groups can explore a group's response to a new product or service. As a program evaluation tool, they can elicit lessons learned and recommendations for performance improvement. The idea is for the researcher to understand participants' reactions. If group members are representative of a larger population, those reactions may be expected to reflect the views of that larger population. Thus, focus groups constitute a research or evaluation method that researchers organize to collect qualitative data through interactive and directed discuss ...

Channel (digital Image)
Color digital images are made of pixels, and pixels are made of combinations of primary colors represented by a series of code. A channel in this context is the grayscale image of the same size as a color image, made of just one of these primary colors. For instance, an image from a standard digital camera will have a red, green and blue channel. A grayscale image has just one channel. In geographic information systems, channels are often referred to as raster bands. Another closely related concept is feature maps, which are used in convolutional neural networks. Overview In the digital realm, there can be any number of conventional primary colors making up an image; a channel in this case is extended to be the grayscale image based on any such conventional primary color. By extension, a channel is any grayscale image of the same dimension as and associated with the original image. ''Channel'' is a conventional term used to refer to a certain component of an image. In reality, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Governor Of The Bank Of Canada
The governor of the Bank of Canada () is the chief executive officer of the Bank of Canada and acts as chair of its board of directors. The ''Bank of Canada Act'', 1985, S. 6(1), provides that the governor and deputy governor shall be appointed by the directors with the approval of the Governor in Council.

EURion Constellation
The EURion constellation (also known as Omron rings or doughnuts) is a pattern of symbols incorporated into a number of secure documents such as banknotes and ownership title certificates designs worldwide since about 1996. It is added to help imaging software detect the presence of such a document in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers. Description The name "EURion constellation" was coined by security researcher Markus Kuhn, who uncovered the pattern on the 10 Euro (€10) banknote in early 2002 while experimenting with a Xerox colour photocopier that refused to reproduce banknotes. Markus KuhnThe EURion constellation Security Group presentation, Computer Laboratory, University of Cambridge, 8 February 2002. The pattern has never been mentioned officially; Kuhn named it the EURion constellation as it resembled the astronomical Orion constellation, and EUR is the ISO 4217 ...

Ultraviolet
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nanometer, nm (with a corresponding frequency around 30 Hertz, PHz) to 400 nm (750 Hertz, THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionization, ionize atoms, it can cause chemical reactions and causes many substances to glow or fluorescence, fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacu ...

Maple Leaf
The maple leaf is the characteristic leaf of the maple tree. It is the most widely recognized national symbol of Canada. History of use in Canada By the early 1700s, the maple leaf had been adopted as an emblem by the French Canadians along the Saint Lawrence River. Its popularity with French Canadians continued and was reinforced when, at the inaugural meeting of the Société Saint-Jean-Baptiste in 1834, the maple leaf was one of numerous emblems proposed to represent the society. Speaking in its favour, Jacques Viger, the first mayor of Montreal, described the maple as "the king of our forest; ... the symbol of the Canadian people." The maple leaf slowly caught on as a national symbol: in 1868, it was included in the coat of arms of Ontario and the coat of arms of Quebec, and was added to the Canadian coat of arms in 1921. Historically, the golden maple leaf had represented Ontario, while the green maple leaf had represented Quebec. In 1867, Alexander Muir composed the p ...

Microprinting
Microprinting is the production of recognizable patterns or characters in a printed medium at a scale that requires magnification to read with the naked eye. To the unaided eye, the text may appear as a solid line. Attempts to reproduce by methods of photocopy, image scanning, or pantograph typically translate as a dotted or solid line, unless the reproduction method can identify and recreate patterns to such scale. Microprint is predominantly used as an anti-counterfeiting technique, due to its inability to be easily reproduced by widespread digital methods. While microphotography precedes microprint, microprint was significantly influenced by Albert Boni in 1934 when he was inspired by his friend, writer and editor Manuel Komroff, who was showing his experimentations related to the enlarging of photographs. It occurred to Boni that if he could reduce rather than enlarge photographs, this technology might enable publication companies and libraries to access much greater quant ...

Intaglio (printmaking)
Intaglio ( ; ) is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print where the parts of the matrix that make the image stand ''above'' the main surface. Normally, copper or in recent times zinc sheets, called plates, are used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint, often in combination. Collagraphs may also be printed as intaglio plates. After the decline of the main relief technique of woodcut around 1550, the intaglio techniques dominated both artistic printmaking as well as most types of illustration and popular prints until the mid 19th century. Process In intaglio printing, the lines to be printed are cut into a metal (e.g. copper) plate by means either of a cutting tool called a burin, held in the hand – in which case the process is called ''engraving''; or t ...

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 documen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inkjet Printing
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals. The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. While working at Canon in Japan, Ichiro Endo suggested the idea for a "Bubble jet" printer, while around the same time Jon Vaught at HP was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, Hewlett-Packard (HP) and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Eps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
