Moiré pattern

In mathematics and art, moiré patterns or moiré fringes are large-scale interference patterns that can be produced when an opaque ruled pattern with transparent gaps is overlaid on another similar pattern. For the moiré interference pattern to appear, the two patterns must not be identical, but rather e.g. displaced, rotated or have different pitch. Moiré patterns appear in many different situations. In printing, the printed pattern of dots can interfere with the image. In television and digital photography, a pattern on an object being photographed can interfere with the shape of the light sensors to generate unwanted artifacts, they are sometimes created deliberately – in micrometers they are used to amplify the effects of small movements. In physics, its manifestation is the beat phenomenon that occurs in many wave interference conditions; the term originates from moire, a type of textile, traditionally of silk but now of cotton or synthetic fiber, with a rippled or "watered" appearance. Moire, or "watered textile", is made by pressing two layers of the textile when wet.

The similar but imperfect spacing of the threads creates a characteristic pattern which remains after the fabric dries. In French, the adjective moiré derives from the earlier verb moirer, "to produce a watered textile by weaving or pressing". Moirer, in turn, is a variation of the word mouaire, an adoption of the English mohair. Mohair comes from a cloth made from the wool of the Angora goat. Mukhayyar descends from khayyara. "Chosen" is meant in the sense of "a choice, or excellent, cloth". Moiré patterns are an artifact of images produced by various digital imaging and computer graphics techniques, for example when scanning a halftone picture or ray tracing a checkered plane; this can be overcome in texture mapping through the use of anisotropic filtering. The drawing on the upper right shows a moiré pattern; the lines could represent fibers in moiré silk. The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of parallel dark and light bands, the moiré pattern, superimposed on the lines.

The moiré effect occurs between overlapping transparent objects. For example, an invisible phase mask is made of a transparent polymer with a wavy thickness profile; as light shines through two overlaid masks of similar phase patterns, a broad moiré pattern occurs on a screen some distance away. This phase moiré effect and the classical moiré effect from opaque lines are two ends of a continuous spectrum in optics, called the universal moiré effect; the phase moiré effect is the basis for a type of broadband interferometer in x-ray and particle wave applications. It provides a way to reveal hidden patterns in invisible layers. Line moiré is one type of moiré pattern. Line moiré is the case when the superposed patterns comprise curved lines; when moving the layer patterns, the moiré patterns move at a faster speed. This effect is called optical moiré speedup. More complex line moiré patterns are created if the lines are curved or not parallel. Shape moiré is one type of moiré pattern demonstrating the phenomenon of moiré magnification.

1D shape moiré is the particular simplified case of 2D shape moiré. One-dimensional patterns may appear when superimposing an opaque layer containing tiny horizontal transparent lines on top of a layer containing a complex shape, periodically repeating along the vertical axis. Moiré patterns revealing complex shapes, or sequences of symbols embedded in one of the layers are created with shape moiré, otherwise called band moiré patterns. One of the most important properties of shape moiré is its ability to magnify tiny shapes along either one or both axes, that is, stretching. A common 2D example of moiré magnification occurs when viewing a chain-link fence through a second chain-link fence of identical design; the fine structure of the design is visible at great distances. Consider two patterns made of parallel and equidistant lines, e.g. vertical lines. The step of the first pattern is p, the step of the second is p + δp, with 0 < δp < p. If the lines of the patterns are superimposed at the left of the figure, the shift between the lines increases when going to the right.

After a given number of lines, the patterns are opposed: the lines of the second pattern are between the lines of the first pattern. If we look from a far distance, we have the feeling of pale zones when the lines are superimposed, of dark zones when the lines are "opposed"; the middle of the first dark zone is when the shift is equal to p/2. The nth line of the second pattern is shifted by n δp compared to the nth line of the first network; the middle of the first dark zone thus corresponds to n ⋅ δ p = p 2, n = p 2 δ p. The distance d between the middle of a pale zone and a dark zone is d = n ⋅ = p 2

Mann Island

Mann Island is a small area in Liverpool, England. It lies on the waterfront next to the River Mersey between the Albert Dock to the south and the Pier Head to the north. Mann Island was formed in the 19th centuries as part of the Liverpool dock complex, it was a virtual island, with Georges Dock to the north, Canning Dock to the east and south, the River Mersey to the west. It was connected to the shoreline by a narrow neck of land opposite James Street, it was the site of the Manchester Dock, opening onto the river, two graving docks, opening into Canning Dock. It was the location of the Great Western Railway warehouses, the Mersey Railway pumping station, all of which are Grade II listed buildings. In the 20th century, it was the site for the James Street station of the Liverpool Overhead Railway; the site ceased to be an "island" in 1899 when the Georges Dock was filled in to provide building land for the Port of Liverpool Building, it became physically joined to the Pier Head. However the name was continued in the roadway.

During the 20th Century Mann Island served as a tram and bus terminus, for routes serving the south of the city, adjoining the Pier Head bus terminus serving the north. Mann Island has been the subject of a number of regeneration schemes, such as the ill-starred Fourth Grace project, under consideration from 2002 to 2006; when this was cancelled, it was replaced by a three part redevelopment scheme. Mann Island has been subject to three redevelopment schemes; the first, occupying the third of the site next to the river, is the Museum of Liverpool, which replaced the Museum of Liverpool Life, opening on 19 July 2011. Secondly, the Liverpool Canal Link, which cuts through Mann Island via a lock system into the Canning Dock; the third, occupying the shoreside half of the site, are the Mann Island Buildings which are three modernist mixed-use private enterprise buildings.

St Erth

St Erth is a civil parish and village in Cornwall, United Kingdom. The village is four miles southeast of St Ives and six miles northeast of Penzance. St Erth takes its name from Saint Erc, one of the many Irish saints who brought Christianity to Cornwall during the Dark Ages, is at the old crossing point of the River Hayle; the Cornish name of the place derives from St Uthinoch of. The parish shares boundaries with Ludgvan in the west, Hayle in the north, St Hilary in the south; the current church of St Erth dates from the 15th century, though an older church is said to have once stood on St Erth Hill overlooking the village. St. Erth has a railway station situated 0.75 miles from the village, along the main line between London Paddington and Penzance the Junction for famous scenic St Ives branch line becoming the new park and ride station for St Ives in June 2019. The old coaching road once led through the village, before the building of the Causeway in 1825 along the edge of the Hayle Estuary.

Prior to 1825 anyone wanting to go from Hayle to St Ives or Penzance had to cross the sands of Hayle Estuary or make a significant detour crossing the River Hayle at the ancient St Erth Bridge. The Star Inn, in St Erth village centre, is a fine coaching inn dating from the fourteenth/fifteenth centuries, it was along this route. Guides took travellers across the sands, but with guides, it was sometimes a perilous journey and the shifting sand and racing tide claimed several lives; because of this major obstacle to trade, a turnpike trust was formed, with Henry Harvey a trustee, to build the causeway which now takes the road below the plantation west to the Old Quay House. Costing £5000 in 1825, the investors charged a toll to use the causeway to recover their costs. Langdon recorded that six stone crosses existed including two in the churchyard. St Erth was the site of a large creamery operated by United Dairies: this was responsible for processing a large quantity of milk produced in Penwith.

Trewinnard Manor is an early 18th-century house built on a different site from its medieval predecessor by the Hawkins family. Trelissick Manor is a medieval house remodelled in 1688 for the Jacobite James Paynter, again remodelled in the 18th century and extended in the 19th century. Tredrea Manor is a 17th-century house but it was rebuilt c. 1856. The front is of five bays built in ashlar. St Erth Sand Pits was the site of choice for the extraction of clay for the fixing of candles to the helmets of miners, it was the site of significant fossil finds and in 1962 was designated a Site of Special Scientific Interest. However, the main use of the sand in this location was for the metal foundries throughout Cornwall and beyond; the sand grains are found coated with a thin film of clay. With gentle pressure and the correct percentage of water the sand grains will bind together and can be used for making a sand mould into which molten metals can be poured from making engineering castings. A good source of clay for the fixing of candles to the helmets of miners was St Agnes Beacon.

The parish church is dedicated to St Erc and is of the 14th century. It has a west tower of three stages. There are south aisles, the arcade in the north aisle having piers of two different types; the church was restored in 1874. The wagon roof of the south porch is old and the font is Norman and of an unusual square design; the ornate wooden roofs of the nave and aisles and fine oak screen decorated with the Four Evangelists are due to the restoration of 1874. The church is sited in a wooded area and the churchyard, according to Charles Henderson, "greatly enhances the building"; the names of eight places in the parish are recorded as having chapels or shrines in the medieval registers, including Bosworgey and Gurlyn. There are six Cornish crosses in the parish: two are in the churchyard and the others are in the churchtown and at Battery Mill and Trevean. For the purposes of local government St Erth forms a civil parish and elects eleven parish councillors every four years to St Erth Parish Council.

The local authority is Cornwall Council. St Erth is twinned with Ploulec' h in France; the Rev. William Paynter, Anglican clergyman and Vice-Chancellor of Oxford University was born at Trelissick Walbert, in the parish of St Erth. David Charleston Cornish-born Australian politician, emigrated to Australia in 1884 and in 1901 he was elected to the Australian Senate Major Herbert Augustine Carter VC son of the vicar of St Erth. Served in two campaigns in East Africa, he is buried at St Erth in a plot planted with tropical plants including laurels and castor oil plants. His Victoria Cross is displayed at the Duke of Cornwall's Light Infantry Museum at Bodmin. Admiral Sir Henry Bernard Hughes Rawlings GBE KCB Royal Navy officer, became Flag Officer, Eastern Mediterranean during World War II. Sir John William Frederic Nott KCB former British Conservative Party MP for St Ives from 1966 to 1983, Secretary of State for Defence during the Falkland war, now lives on his farm in St Erth Tyrrell, Stephen Trewinnard: a Cornish History.
