Dot matrix

A dot matrix is a 2-dimensional patterned array, used to represent characters and images. Every type of modern technology uses dot matrices for display of information, including mobile phones and printers, they are used in textiles with sewing and weaving. An alternate form of information display using lines and curves is known as a vector display, was used with early computing devices such as air traffic control radar displays and pen-based plotters but is no longer used. Electronic vector displays were monochrome only, either don't fill in the interiors of closed vector shapes, or shape-filling is slow, time-consuming, non-uniform, as on pen-based plotters. In printers, the dots are the darkened areas of the paper. In displays, the dots may light up, as in an LED, CRT, or plasma display, or darken, as in an LCD. Although the output of modern computers is all in the form of dot matrices, computers may internally store data as either a dot matrix or as a vector pattern of lines and curves. Vector data encoding requires less memory and less data storage, in situations where the shapes may need to be resized, as with font typefaces.

For maximum image quality using only dot matrix fonts, it would be necessary to store a separate dot matrix pattern for the many different potential point sizes that might be used. Instead, a single group of vector shapes is used to render all the specific dot matrix patterns needed for the current display or printing task. All points addressable, or pixel addressable, in the context of a dot matrix on a computer monitor or any display device consisting of a pixel array, refers to an arrangement whereby bits or cells can be individually manipulated, as opposed to rewriting the whole array, or regions such as characters, every time a change is needed. Text modes are not all-points-addressable, whereas graphics modes are. With the advent of more powerful computer graphics hardware, the use and importance of text-only display modes has declined, with graphics modes it is taken for granted that they are all-points-addressable; the process of doing dot matrix printing can involve dot matrix printers, both for impact and non-impact printers.

All modern computer printers create their output as matrices of dots, they may use laser printing inkjet printing dot matrix printersExcept for impact dot matrix printers, it is not customary to call the others by that term. Printers that are not but what the New York Times calls a "dot-matrix impact printer" are not called dot matrix printers. Impact printers survive where multi-part forms are needed, as the pins can impress dots through multiple layers of paper to make a carbonless copy, for security purposes; as an impact printer, the term refers to low-resolution impact printers, with a column of 8, 9 or 24 "pins" hitting an ink-impregnated fabric ribbon, like a typewriter ribbon, onto the paper. It was contrasted with both daisy wheel printers and line printers that used fixed-shape embossed metal or plastic stamps to mark paper. All types of electronic printers generate image data as a two-step process. First the information to be printed is converted into a dot matrix using a raster image processor, the output is a dot matrix referred to as a raster image, a complete full-page rendering of the information to be printed.

Raster image processing may occur in either the printer itself using a page description language such as Adobe Postscript, or may be performed by printer driver software installed on the user's computer. Early 1980s impact printers used a simple form of internal raster image processing, using low-resolution built-in bitmap fonts to render raw character data sent from the computer, only capable of storing enough dot matrix data for one printed line at a time. External raster image processing was possible such as to print a graphical image, but was extremely slow and data was sent one line at a time to the impact printer. Depending on the printer technology the dot size or grid shape may not be uniform; some printers are capable of producing smaller dots and will intermesh the small dots within the corners larger ones for antialiasing. Some printers have a fixed resolution across the printhead but with much smaller micro-stepping for the mechanical paper feed, resulting in non-uniform dot-overlapping printing resolutions like 600×1200 dpi.

A dot matrix is useful for marking materials other than paper. In manufacturing industry, many product marking applications use dot matrix inkjet or impact methods; this can be used to print 2D matrix codes, e.g. Datamatrix. A LED matrix or LED display is a large, low-resolution form of dot-matrix display, useful both for industrial and commercial information displays as well as for hobbyist human–machine interfaces, it consists of a 2-D diode matrix with their cathodes joined in rows and their anodes joined in columns. By controlling the flow of electricity through each row and column pair it is possible to control each LED individually. By multiplexing, scanning across rows flashing the LEDs on and off, it is possible to create characters or pictures to display information to the user. By varying the pulse rate per LED, the display can approximate levels of brightness. Multi-colored LEDs or RGB-colored LEDs permit use as a full-color image display; the refresh rate is fast enough to prevent the human eye from detecting the flicker.

The primary difference between a common LED matrix and an OLED display is the large, low resolution dots. The OLED monitor functionally works the same, except there are many times more dots, they are all much smaller, allowing for greater detail in the displayed patterns. Dot ma

Patricia Sutherland

Patricia Sutherland is a Canadian archaeologist, specialising in the Arctic. Much of her recent research has focused on evidence of a lengthy Norse presence on Baffin Island in the 11th to 13th centuries CE and trade between them and the now-extinct Dorset people of the region. Sutherland's theory that there were Europeans on Baffin Island hundreds of years before the Norse settled Greenland at the start of the 11th century is controversial. Sutherland holds a PhD from the University of Alberta, she is an Adjunct Research Professor at Carleton University in Ottawa and an Honorary Research Fellow at the University of AberdeenUntil April 2012, she was employed at the Canadian Museum of Civilization, now the Canadian Museum of History, most as curator of Arctic archaeology. She was the only female archaeologist working there, it has been speculated, including by the CBC programme The Fifth Estate, that she was let go because her research no longer fit with the changed focus of the museum on Canadian history, some have suggested that the political motivation extends to a fear that her research will undermine Canadian sovereignty claims in the high Arctic.

Other speculation points to her having been one of six staff of the museum who wrote a letter objecting on moral grounds to its acquisition of a collection of artefacts taken from the wreck of RMS Empress of Ireland. When Sutherland was fired, her access to her research materials was cut off and many were dispersed. There have been calls by fellow archaeologists and a petition for her to be allowed to resume her research. Sutherland is an expert in Canadian indigenous archaeology. In 1977, surveying what was to become Quttinirpaaq National Park, on Ellesmere Island, for Parks Canada, she found a piece of bronze that turned out to be half of a Norse silver weighing balance. In 1979, on Axel Heiberg Island, she found a piece of antler on which two different faces were carved: one with round-faced Dorset features, the other thin-faced and with heavy eyebrows. In 1999, she discovered among finds from a Dorset site near Pond Inlet, on northern Baffin Island, a piece of spun yarn or cordage that did not conform with the twine made of animal sinews used by the Inuit but did correspond to that used in the 14th century in Norse settlements in Greenland.

This and evidence of metalworking–bronze and smelted iron, in addition to whetstones used for sharpening metal implements–and tally sticks like those used by the Norse, found at four sites where Dorset people had camped as much as 1,000 miles apart between northern Baffin Island and northern Labrador, suggested both long-term trading contact between the Norse and the Dorset, a long-term presence of Norsemen in the region. She presented her view at an exhibition titled Full Circle: First Contact and Skraelings in Newfoundland and Labrador, which opened at the Provincial Museum of Newfoundland and Labrador in summer 2000, at a meeting of the Council for Northeast Historical Archaeology in St. John's in October 2012. Further excavating the Nanook site at Tanfield Valley on southern Baffin Island, she has found fur from Old World rats, a whalebone shovel like those used in Viking Greenland to cut turf, evidence of European-style masonry, more whetstones and tally sticks, a Dorset-style carved mask that depicts a face with European features.

She has continued to find evidence of Norse metalworking elsewhere in the region. The radiocarbon dates of items at the Nanook site include some predating the Norse by several hundred years. Sutherland suggests. Sutherland argues, it is possible that at least some of the artefacts are spoils of war. Sutherland's theory that the spun yarn or cordage of Arctic hare fur is evidence of possible European contact with the Dorset is controversial. Elizabeth Wayland Barber of Occidental College and expert on textiles, writing about the Lascaux caves in France, "We now have at least two pieces of evidence that this important principle of twisting for strength dates to the Palaeolithic. Michele Hayeur Smith of Brown University, "The idea that you would have to learn to spin something from another culture was a bit ludicrous," she said. "It's a pretty intuitive thing to do." William W. Fitzhugh, Director of the Arctic Studies Center at the Smithsonian Institution in Washington, a Senior Scientist at the National Museum of Natural History, says that there is insufficient published evidence to support Sutherland's claims, that the Dorset themselves were using spun cordage by the 6th century.

One of the pieces of 2-ply spun Arctic hare fur cordage, item KdDq-9-3:4797, returned an accelerator mass spectrometry radiocarbon calibrated age of calAD 73-226. Sutherland does not believe that piece of Arctic hare fur cordage was the work of the Dorset, but was the work of a European; the international Helluland Project, organised by Sutherland, was to have published a book on her findings.

Tsvetan Radoslavov

Cvetan Radoslavov Hadžidenkov was a Bulgarian teacher and the author of the current national anthem of Bulgaria, Mila Rodino. Born in Svishtov in 1863, he graduated in philosophy in Leipzig. In 1885, while en route to the battlefield during the Serbo-Bulgarian War, Radoslavov composed the song Gorda Stara Planina, polished by the composer Dobri Hristov in 1905 and became a national anthem of Bulgaria in 1963 as Mila Rodino. Besides creating the Bulgarian national anthem, Radoslavov was a prominent scientist, he was one of the three Bulgarians that took their doctor's degree by the father of modern psychology, Wilhelm Wundt. Rejecting invitations to work as a teacher in Vienna and Prague, he returned to Bulgaria to work at the Third High School for Boys in Sofia, believing he was helping the development of modern Bulgaria by teaching students European and ancient languages, psychology and logic. Radoslavov lived in a small apartment at 3 Angel Kanchev Street, where he is today commemorated by a plaque by Georgi Chapkanov.
