Optical Imaging
Medical optical imaging is the use of light as an investigational :wikt:imaging, imaging technique for medical applications. Examples include optical microscopy, spectroscopy, endoscopy, scanning laser ophthalmoscopy, laser Doppler imaging, and optical coherence tomography. Because light is an electromagnetic wave, similar phenomena occur in X-rays, microwaves, and radio waves. Optical imaging systems may be divided into diffusive and ballistic imaging systems. A model for photon migration in turbid biological media has been developed by Bonner et al. Such a model can be applied for interpretation data obtained from laser Doppler blood-flow monitors and for designing protocols for therapeutic excitation of tissue chromophores. Diffusive optical imaging Diffuse optical imaging (DOI) is a method of imaging using near-infrared spectroscopy (NIRS) or fluorescence-based methods. When used to create 3D volumetric models of the imaged material DOI is referred to as diffuse optical tomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antilles
The Antilles (; gcf, label=Antillean Creole, Antiy; es, Antillas; french: Antilles; nl, Antillen; ht, Antiy; pap, Antias; Jamaican Patois: ''Antiliiz'') is an archipelago bordered by the Caribbean Sea to the south and west, the Gulf of Mexico to the northwest, and the Atlantic Ocean to the north and east. The Antillean islands are divided into two smaller groupings: the Greater Antilles and the Lesser Antilles. The Greater Antilles includes the larger islands of the Cayman Islands, Cuba, Hispaniola (subdivided into the nations of the Dominican Republic and Haiti), Jamaica, and Puerto Rico. The Lesser Antilles contains the northerly Leeward Islands and the southeasterly Windward Islands as well as the Leeward Antilles just north of Venezuela. The Lucayan Archipelago (consisting of The Bahamas and the Turks and Caicos Islands), though a part of the West Indies, is generally not included among the Antillean islands. Geographically, the Antillean islands are generally consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sailing At The 1952 Summer Olympics
Sailing/Yachting is an Olympic sport starting from the Games of the 1st Olympiad (1896 Olympics in Athens, Greece). With the exception of 1904 and the canceled 1916 Summer Olympics, sailing has always been included on the Olympic schedule. The Sailing program of the 1952 Summer Olympics consisted of a total of five sailing classes (disciplines). For each class seven races were scheduled from 20–28 July 1952 of the coast of Harmaja. The sailing was done on the triangular type Olympic courses. The start was made in the center of a set of 8 numbered marks that were places in a circle. During the starting procedure the sequence of the marks was communicated to the sailors. By picking the mark that was most upwind the start could always be made upwind. This system is, at least in certain German lakes, still in use. Venue Two course areas were created in front of Helsinki. One for the Finn just outside the island Liuskasaari. The Finn course was 5.4 nm long and triangular in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectroscopy
Spectroscopy is the field of study that measures and interprets the electromagnetic spectra that result from the interaction between electromagnetic radiation and matter as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. Historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and e ...

Sailing At The 1952 Summer Olympics - 5
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' (land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail. Sail was slowly replaced by steam as the method of propulsion for ships over the latter part of the 19th century – seeing a gradual improvement in the technology of steam through a number of stepwise developments. Steam allowed scheduled services that ran at higher average speeds than sailing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1952 Summer Olympics
The 1952 Summer Olympics ( fi, Kesäolympialaiset 1952; sv, Olympiska sommarspelen 1952), officially known as the Games of the XV Olympiad ( fi, XV olympiadin kisat; sv, Den XV olympiadens spel) and commonly known as Helsinki 1952 ( sv, Helsingfors 1952), were an international multi-sport event held from 19 July to 3 August 1952 in Helsinki, Finland. After Japan declared in 1938 that it would be unable to host 1940 Olympics in Tokyo due to the ongoing Second Sino-Japanese War, Helsinki had been selected to host the 1940 Summer Olympics, which were then cancelled due to World War II. Tokyo eventually hosted the games in 1964. Helsinki is the northernmost city at which a summer Olympic Games have been held. With London hosting the 1948 Olympics, 1952 is the most recent time when two consecutive summer Olympics Games were held entirely in Europe. The 1952 Summer Olympics was the last of the two consecutive Olympics to be held in Northern Europe, following the 1952 Winter Olympics ...

Sailing (sport)
The sport of sailing involves a variety of competitive sailing formats that are sanctioned through various sailing federations and yacht clubs. Racing disciplines include matches within a fleet of sailing craft, between a pair thereof or among teams. Additionally, there are specialized competitions that include setting speed records. Racing formats include both closed courses and point-to-point contests; they may be in sheltered waters, coast-wise or on the open ocean. Most competitions are held within defined classes or ratings that either entail one type of sailing craft to ensure a contest primarily of skill or rating the sailing craft to create classifications or handicaps. On water, a sailing competition among multiple vessels is a regatta, which usually consists of multiple individual races, where the boat crew that performs best in over the series of races is the overall winner. There is a broad variety of kinds of races and sailboats used for racing from large yacht to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
