Canton Tower
The Canton Tower (), formally Guangzhou TV Astronomical and Sightseeing Tower (), is a -tall multipurpose observation tower in the Haizhu District of Guangzhou ( alternatively romanized as ''Canton''). The tower was topped out in 2009 and it became operational on 29 September 2010 for the 2010 Asian Games. The tower briefly held the title of tallest tower in the world, replacing the CN Tower, before being surpassed by the Tokyo Skytree. It was the tallest structure in China prior to the topping out of the Shanghai Tower on 3 August 2013, and is now the second-tallest tower and the fifth-tallest freestanding structure in the world. Naming and etymology There had been a long discussion about the naming of the Canton Tower since the commencement of its construction in 2005 after the groundbreaking ceremony. In September 2020, at the request of the tower's investor, ''Guangzhou Daily'' launched a contest for naming proposals. The contest attracted over valid entries, among w ...

CN Tower
The CN Tower (french: Tour CN) is a concrete communications and observation tower in downtown Toronto, Ontario, Canada. Built on the former Railway Lands, it was completed in 1976. 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 real estate development. 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 ninth-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 Wonders of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Towers In The World
Several extant building fulfill the engineering definition of a tower: "a tall human structure, always taller than it is wide, for public or regular operational access by humans, but not for living in or office work, and are ''self-supporting'' or ''free-standing'', which means no guy-wires for support." This definition excludes continuously habitable buildings and skyscrapers as well as radio and TV masts. Also excluded because they are not designed for public or regular operational access are bridge towers or pylons, wind turbines, chimneys, transmission towers, sculptures and most large statues and obelisks. Towers are most often built to use their height for various purposes, and can stand alone or as part of a larger structure. Some common purposes are for telecommunications, and as a viewing platform. The Tokyo Skytree, completed in February 2012, is , making it the tallest tower, and third-tallest free-standing structure in the world. Entirely self-supported towers ...

Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric railway, electric) that operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between rapid transit station, stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train a ...

4-D Film
4D film is a high technology multisensory presentation system combining motion pictures with physical effects that are synchronized and occur in the theatre. Effects simulated in 4D films include motion, vibration, scent, rain, mist, bubbles, fog, smoke, wind, temperature changes, and strobe lights. Advanced seats in 4D venues vibrate and move during these multisensory presentations. Other common effects include air jets and water sprays. Auditorium effects may include smoke, rain, lightning, bubbles, and scent. 4D films are exhibited in every major global market in stadium seating multiplexes and are exhibited via worldwide theatrical releases. Multinational mobile 4D theatres include Cinetransformer venues. And as of 2022, 4D films are exhibited in more than 65 countries globally. 4D motion pictures are also exhibited in theme parks. History The precursors of the modern 4D film presentation include Sensurround, which debuted in 1974 with the film ''Earthquake''. Only a few f ...

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. Types * Meeting facilities with lodging: hotels that include their own convention space in addition to accommodation and other related facilities, known as convention hotels. * Meeting facilities without lodging: are convention centers that do not include accommodation; usually located adjacent to or near a hotel(s). * Other: any convention and meeting facilities designed t ...

Transmission (telecommunications)
In telecommunications, transmission is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. Transmission technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, 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 packet of data, a phone call, or an email. See also *Radio transmitter In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adziogol Lighthouse

Vladimir Shukhov
Vladimir Grigoryevich Shukhov (russian: link=no, Влади́мир Григо́рьевич Шу́хов; – 2 February 1939) was a Russian Empire 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 shell structures, tensile structures, gridshell structures, oil reservoirs, pipelines, boilers, ships and barges. He is also the inventor of the 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. ...

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 creati ...

Silk Road
The Silk Road () was a network of Eurasian trade routes active from the second century BCE until the mid-15th century. Spanning over 6,400 kilometers (4,000 miles), it played a central role in facilitating economic, cultural, political, and religious interactions between the Eastern world, East and Western world, West. The name "Silk Road", first coined in the late 19th century, has fallen into disuse among some modern historians in favor of Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting East Asia, East and Southeast Asia, the South Asia, Indian subcontinent, Central Asia, the Middle East, East Africa and Southern Europe, Europe. The Silk Road derives its name from the highly lucrative trade of silk, silk textiles that were Silk industry in China, produced almost exclusively in China. The network began with the Han dynasty, Han dynasty's expansion into Central Asia around 114 BCE, Protectorate of the Western Regio ...
