Cobweb
A spider web, spiderweb, spider's web, or cobweb (from the archaic word '' coppe'', meaning "spider") is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey. Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, in southern England. Many spiders build webs specifically to trap and catch insects to eat. However, not all spiders catch their prey in webs, and some do not build webs at all. "Spider web" is typically used to refer to a web that is apparently still in use (i.e. clean), whereas "cobweb" refers to abandoned (i.e. dusty) webs. However, the word "cobweb" is also used by biologists to describe the tangled three-dimensional web of some spiders of the family Theridiidae. While this large family is known as the cobweb spiders, they actually have a huge range of web architectures; other names for this spider family include tang ...

Sempervivum Arachnoideum
''Sempervivum arachnoideum'', the cobweb house-leek, is a species of flowering plant in the family Crassulaceae, native to European mountains, in the Alps, Apennines and Carpathians. Growing to tall by wide, it is a rosette-forming succulent perennial, valued in cultivation for its ability to colonise hot, dry areas via offsets. The specific epithet ''arachnoideum'' refers to its furry central rosettes (long ciliate leaf margins), resembling spider webs. It flowers in July, with pink flowers that are raised on stems and are hermaphroditic (having both male and female organs). This plant, and the subspecies ''Sempervivum arachnoideum'' subsp. ''tomentosum'', have gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit .... ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobweb Theory
The cobweb model or cobweb theory is an economic model that explains why prices might be subject to periodic fluctuations in certain types of markets. It describes cyclical supply and demand in a market where the amount produced must be chosen before prices are observed. Producers' expectations about prices are assumed to be based on observations of previous prices. Nicholas Kaldor analyzed the model in 1934, coining the term "cobweb theorem" (see Kaldor, 1938 and Pashigian, 2008), citing previous analyses in German by Henry Schultz and Umberto Ricci. The model The cobweb model is generally based on a time lag between supply and demand decisions. Agricultural markets are a context where the cobweb model might apply, since there is a lag between planting and harvesting (Kaldor, 1934, p. 133-134 gives two agricultural examples: rubber and corn). Suppose for example that as a result of unexpectedly bad weather, farmers go to market with an unusually small crop of strawberries ...

Cobweb Spider
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world. Theridiid spiders are both entelegyne, meaning that the females have a genital plate, and ecribellate, meaning that they spin sticky capture silk instead of woolly silk. They have a comb of serrated bristles (setae) on the tarsus of the fourth leg. The family includes some model organisms for research, including the medically important widow spiders. They are important to studies characterizing their venom and its clinical manifestation, but widow spiders are also used in research on spider silk and sexual biology, including sexual cannibalism. ''Anelosimus'' are also model organisms, used for the study of sociality, because it has evolv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobweb Plot
A cobweb plot, or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions, such as the logistic map. Using a cobweb plot, it is possible to infer the long term status of an initial condition under repeated application of a map. Method For a given iterated function ''f'': R → R, the plot consists of a diagonal (x = y) line and a curve representing y = f(x). To plot the behaviour of a value x_0, apply the following steps. # Find the point on the function curve with an x-coordinate of x_0. This has the coordinates (x_0, f(x_0)). # Plot horizontally across from this point to the diagonal line. This has the coordinates (f(x_0), f(x_0)). # Plot vertically from the point on the diagonal to the function curve. This has the coordinates (f(x_0), f(f(x_0))). # Repeat from step 2 as required. Interpretation On the cobweb plot, a stable fixed point corresponds to an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cobweb Bridge
The Cobweb Bridge, also known as Spider Bridge, is located in the city centre of Sheffield, South Yorkshire, England, near the disused Sheffield Victoria railway station. Completed in 2002, its design solves a difficult problem: passing the riverside cycle- and footpath (the Five Weirs Walk) under the massive Wicker Arches viaduct while linking one bank of the River Don to the other. Without the Cobweb Bridge, the footpath would have had to make a one-mile detour. Designed by Sheffield City Council's Structures Section, the entire long bridge is suspended on a web of steel cables secured to the underside of the viaduct, hence the name. Completing the theme, large steel likenesses of spiders conceal the overhead lighting. While the bridge has been prone to vandalism in the past (the wires forming the parapet having been stolen more than once), the bridge was repaired in 2015 to reduce the risk of future vandalism. The newly restored bridge no longer uses wires in the parapet, ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sailing At The 1908 Summer Olympics – 8 Metre Class
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, Windsurfing, windsurfer, or Kitesurfing, kitesurfer), on ''ice'' (iceboat) or on ''land'' (Land sailing, land yacht) over a chosen Course (navigation), 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 sche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobweb (clustering)
COBWEB is an incremental system for hierarchical conceptual clustering. COBWEB was invented by Professor Douglas H. Fisher, currently at Vanderbilt University. COBWEB incrementally organizes observations into a classification tree Classification chart or classification tree is a synopsis of the classification scheme, designed to illustrate the structure of any particular field. Overview Classification is the process in which ideas and objects are recognized, differentia .... Each node in a classification tree represents a class (concept) and is labeled by a probabilistic concept that summarizes the attribute-value distributions of objects classified under the node. This classification tree can be used to predict missing attributes or the class of a new object. There are four basic operations COBWEB employs in building the classification tree. Which operation is selected depends on the category utility of the classification achieved by applying it. The operations are: * Mergi ...
