CN Tower
The CN Tower () is a communications and observation tower in Toronto, Ontario, Canada. Completed in 1976, it is located in downtown Toronto, built on the former Railway Lands. Its name "CN" referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets prior to the company's privatization in 1995, it transferred the tower to the Canada Lands Company, a federal Crown corporation responsible for the government's real estate portfolio. The CN Tower held the record for the world's tallest free-standing structure for 32 years, from 1975 until 2007, when it was surpassed by the Burj Khalifa, and was the world's tallest tower until 2009 when it was surpassed by the Canton Tower. It is currently the tenth-tallest free-standing structure in the world and remains the tallest free-standing structure on land in the Western Hemisphere. In 1995, the CN Tower was declared one of the modern Seven W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exhibition Hall
A convention center (American English; or conference centre in British English) is a large building that is designed to hold a convention, where individuals and groups gather to promote and share common interests. Convention centers typically offer sufficient floor area to accommodate several thousand attendees. Very large venues, suitable for major trade shows, are sometimes known as exhibition halls. Convention centers typically have at least one auditorium and may also contain concert halls, lecture halls, meeting rooms, and conference rooms. Some large resort area hotels include a convention center. In Francophone countries, the term is palais des congrès (such as the Palais des Congrès de Paris) or centre des congrès (such as the Centre des congrès de Quebec).

Transmission (telecommunications)
In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an Analog signal, analog or digital signal via a transmission medium, medium that is wired communication, wired, wireless, or fiber-optic communication, fiber-optic. Transmission system technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, Equalization (communications), equalization, error control, bit synchronization and multiplexing, but it may also involve higher-layer protocol duties, for example, digitizing an analog signal, and data compression. Transmission of a digital message, or of a digitized analog signal, is known as data transmission. Examples of transmission are the sending of signals with limited duration, for example, a block or Network packet, packet of data, a phone call, or an email.

Hyperboloid Shuckhov Tower In Guangzhou During Construction
In geometry, a hyperboloid of revolution, sometimes called a circular hyperboloid, is the surface generated by rotating a hyperbola around one of its principal axes. A hyperboloid is the surface obtained from a hyperboloid of revolution by deforming it by means of directional scalings, or more generally, of an affine transformation. A hyperboloid is a quadric surface, that is, a surface defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, a hyperboloid is characterized by not being a cone or a cylinder, having a center of symmetry, and intersecting many planes into hyperbolas. A hyperboloid has three pairwise perpendicular axes of symmetry, and three pairwise perpendicular planes of symmetry. Given a hyperboloid, one can choose a Cartesian coordinate system such that the hyperboloid is defined by one of the following equations: + - = 1, or + - = -1. The coordinate axes are axes of symmetry of the hyperboloid and the origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adziogol Lighthouse
__NOTOC__ The Adziogol Lighthouse (), also known as Stanislav–Adzhyhol Lighthouse or Stanislav Range Rear light, is one of two vertical lattice hyperboloid structures of steel bars, serving as active lighthouses in Dnieper Estuary, Ukraine. It is located about west of the city of Kherson. At a height of , it is the sixteenth-tallest "traditional lighthouse" in the world as well as the tallest in Ukraine. Location It is located on a concrete pier on a tiny islet in the combined Dnieper-Bug Estuary, which extends eastward into the Dnieper Estuary, a part of the Dnieper River delta, about north of the village of Rybalche (Skadovsk Raion) and south of the Cape of Adzhyhol, for which it is named. Together with the Stanislav Range Front Light (Small Adzhyhol Lighthouse), it serves as a range light, guiding ships entering the Dnieper River or the Southern Buh River within the vast Dnieper-Bug Estuary.

Vladimir Shukhov
Vladimir Grigoryevich Shukhov (; – 2 February 1939) was a Russian and Soviet engineer-polymath, scientist and architect renowned for his pioneering works on new methods of analysis for structural engineering that led to breakthroughs in industrial design of the world's first hyperboloid structures, diagrid Thin-shell structure, shell structures, tensile structures, gridshell structures, oil reservoirs, Pipeline transport, pipelines, boilers, ships and barges. He is also the inventor of the Shukhov cracking process, first cracking method. Besides the innovations he brought to the oil industry and the construction of numerous bridges and buildings, Shukhov was the inventor of a new family of doubly curved structural forms. These forms, based on non-Euclidean hyperbolic geometry, are known today as hyperboloids of revolution. Shukhov developed not only many varieties of light-weight hyperboloid towers and roof systems, but also the mathematics for their analysis. Shukhov is part ...

Hyperboloid Structure
Hyperboloid structures are architectural structures designed using a hyperboloid in one sheet. Often these are tall structures, such as towers, where the hyperboloid geometry's structural strength is used to support an object high above the ground. Hyperboloid geometry is often used for decorative effect as well as structural economy. The first hyperboloid structures were built by Russian engineer Vladimir Shukhov (1853–1939), including the Shukhov Tower in Polibino, Dankovsky District, Lipetsk Oblast, Russia. Properties Hyperbolic structures have a negative Gaussian curvature, meaning they curve inward rather than curving outward or being straight. As doubly ruled surfaces, they can be made with a lattice of straight beams, hence are easier to build than curved surfaces that do not have a ruling and must instead be built with curved beams. Hyperboloid structures are superior in stability against outside forces compared with "straight" buildings, but have shapes often cre ...

Silk Road
The Silk Road was a network of Asian trade routes active from the second century BCE until the mid-15th century. Spanning over , it played a central role in facilitating economic, cultural, political, and religious interactions between the Eastern world, Eastern and Western worlds. The name "Silk Road" was coined in the late 19th century, but some 20th- and 21st-century historians instead prefer the term Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting Central Asia, Central, East Asia, East, South Asia, South, Southeast Asia, Southeast, and West Asia as well as East Africa and Southern Europe. The Silk Road derives its name from the highly lucrative trade of silk textiles that were History of Silk, primarily produced in China. The network began with the expansion of the Han dynasty (202 BCE220 CE) into Central Asia around 114 BCE, through the missions and explorations of the Chinese imperial env ...
