County Hall, London
County Hall (sometimes called London County Hall) is a building in the district of Lambeth, London that was the headquarters of London County Council (LCC) and later the Greater London Council (GLC). The building is on the South Bank of the River Thames, beside Westminster Bridge. It faces west toward the City of Westminster and is close to the Palace of Westminster. The nearest London Underground stations are and . It is a Grade II* listed building. History The building was commissioned to replace the mid 19th-century Spring Gardens headquarters inherited from the Metropolitan Board of Works. The site selected by civic leaders was previously occupied by four properties: Float Mead (occupied by Simmond's flour mills), Pedlar's Acre (occupied by wharves and houses), Bishop's Acre (occupied by Crosse & Blackwell's factory) and the Four Acres (occupied by workshops and stables). The main six storey building was designed by Ralph Knott. It is faced in Portland stone in an Edw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balikpapan-class Landing Craft Heavy
The ''Balikpapan'' class is a class of eight heavy landing craft. All eight were built by Walkers Limited for the Australian Army in the early 1970s. A reorganisation of watercraft responsibilities in the Australian military meant the landing craft were operated by the Royal Australian Navy (RAN), with seven commissioned directly into RAN service during 1973 and 1974, and lead ship transferred from the army to the navy. During the leadup to the History of Papua New Guinea#Independence, independence of Papua New Guinea in 1975, two of the vessels ( and ) were transferred to the new Papua New Guinea Defence Force (PNGDF). During their careers, the Australian vessels have operated in support of Operation Navy Help Darwin in 1974–1975, Operation Bel Isi from 1997 to 2003, INTERFET operations in 1999 and 2000, and RAMSI operations from 2003. The six remaining RAN vessels were paid off in the 2010s: ''Balikpapan'', , and in 2012; , , and in 2014. They are yet to be replaced in RAN ...

Color Space
A color space is a specific organization of colors. In combination with color profiling supported by various physical devices, it supports reproducible representations of colorwhether such representation entails an analog or a digital representation. A color space may be arbitrary, i.e. with physically realized colors assigned to a set of physical color swatches with corresponding assigned color names (including discrete numbers infor examplethe Pantone collection), or structured with mathematical rigor (as with the NCS System, Adobe RGB and sRGB). A "color space" is a useful conceptual tool for understanding the color capabilities of a particular device or digital file. When trying to reproduce color on another device, color spaces can show whether shadow/highlight detail and color saturation can be retained, and by how much either will be compromised. A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HCL Color Space
HCL ( hue– chroma–luminance) or LCh refers to any of the many cylindrical color space models that are designed to accord with human perception of color with the three parameters. Lch has been adopted by information visualization practitioners to present data without the bias implicit in using varying saturation. They are, in general, designed to have characteristics of both cylindrical translations of the RGB color space, such as HSL and HSV, and the L*a*b* color space. Derivation Color-making attributes HCL concerns the following attributes of color appearance: ; Hue: The "attribute of a visual sensation according to which an area appears to be similar to one of the perceived colors: red, yellow, green, and blue, or to a combination of two of them".Fairchild (2005)/ref> ; Lightness, value: The "brightness relative to the brightness of a similarly illuminated white". ; Luminance (''Y'' or ''L''v,Ω): The radiance weighted by the effect of each wavelength on a typica ...

Locally Compact Hausdorff Space
In topology and related branches of mathematics, a topological space is called locally compact if, roughly speaking, each small portion of the space looks like a small portion of a compact space. More precisely, it is a topological space in which every point has a compact neighborhood. When locally compact spaces are Hausdorff they are called locally compact Hausdorff, which are of particular interest in mathematical analysis. Formal definition Let ''X'' be a topological space. Most commonly ''X'' is called locally compact if every point ''x'' of ''X'' has a compact neighbourhood, i.e., there exists an open set ''U'' and a compact set ''K'', such that x\in U\subseteq K. There are other common definitions: They are all equivalent if ''X'' is a Hausdorff space (or preregular). But they are not equivalent in general: :1. every point of ''X'' has a compact neighbourhood. :2. every point of ''X'' has a closed compact neighbourhood. :2′. every point of ''X'' has a relatively compac ...

Life-cycle Hypothesis
In economics, the life-cycle hypothesis (LCH) is a model that strives to explain the consumption patterns of individuals. Theory and evidence Elderly dissaving is also influenced by the present factors that materially prevent them from the possibility of spending their previous savings. One of them is the loss of the driving license. An extended survey held in 1998, 2000, and 2002 among the U.S. retired citizens highlighted that "about 90% of the trips among people older than age 65 are in a private vehicle" and that driving cessation was highly correlated (46% to 63%, Tobit regression) to a reduction in spending on non basic needs such as trips, tickets, and dinings out. It is also relevant to distinguish elderly poor people in two basic tipologies: people who are poor on income, or those who are poor in terms of both income and consumption. While the life cycle hypothesis predicts the income and the consumption patterns of the elderly population, a series of research papers pub ...

Korea Aerospace Industries
Korea Aerospace Industries, Ltd. (KAI; ) is a South Korean aerospace and defense manufacturer. It was originally established as a joint venture of Daewoo Heavy Industries' aerospace division, Samsung Aerospace, and Hyundai Space and Aircraft. p. 97 During 1999, KAI became more independent of its founding members, acquiring their aerospace interests at the behest of the South Korean government following the financial troubles of these companies that had resulted from the 1997 Asian financial crisis. KAI has developed various aerospace products, including the Korean Space Launch Vehicle-II (KSLV-II) and various satellites. It has been involved in the production of several foreign-designed aircraft via licensing arrangements, such as the MBB/Kawasaki BK 117, MBB Bo-105 KLH, and the KF-16. KAI has also developed and produced its own aircraft designs, including the KT-1 Woongbi and T-50 Golden Eagle training aircraft, the KC-100 Naraon general aviation aircraft, and the KU ...

KAI LCH
The KAI LCH (Light Civil Helicopter, ) is a medium-sized twin-engined civil helicopter manufactured by the South Korean aerospace manufacturer Korea Aerospace Industries (KAI). It is derived from the Eurocopter EC155 and is closely related to the Light Armed Helicopter (LAH), a militarised rotorcraft intended for battlefield operations. Development of the LCH commenced in June 2015 with an agreement between the multinational rotorcraft manufacturer Airbus Helicopters and KAI under which the former committed to transferring production of the EC155 to the latter, while the two companies would jointly market, sell, and develop the type for the international market. On 24 July 2018, the first prototype LCH made its maiden flight in Marignane, France. On 5 December 2019, the second prototype made its first flight from Sacheon, South Korea. During September 2022, type certification for the LCH was received from the South Korean aviation authorities; the first production rotorcraft was ...

HAL Light Combat Helicopter
The HAL Prachand () is an Indian multi-role light attack helicopter designed and manufactured by Hindustan Aeronautics Limited (HAL) under Project ''Light Combat Helicopter'' (LCH). It has been ordered by the Indian Air Force (IAF) and the Indian Army's Aviation Corps (AAC). On 3 October 2022, the LCH was formally inducted into the IAF and was officially named "''Prachand''". The true impetus for the development of the LCH Prachand came in the form of the Kargil War, a conflict fought between India and neighbouring Pakistan in 1999, which revealed the Indian Armed Forces lacked a suitable armed rotorcraft capable of operating unrestricted in the high-altitude theatre. Accordingly, both HAL and the Indian Armed Forces commenced exploratory efforts towards the conceptualisation of a combat helicopter to perform in this role. During 2006, the company announced that it had launched a development programme to produce such a rotorcraft, referred to simply as the LCH or Light Combat ...

Intersex
Intersex people are those born with any of several sex characteristics, including chromosome patterns, gonads, or genitals that, according to the Office of the United Nations High Commissioner for Human Rights, "do not fit typical binary notions of male or female bodies". Sex assignment at birth usually aligns with a child's external genitalia. The number of births with ambiguous genitals is in the range of 1:4,500–1:2,000 (0.02%–0.05%). Other conditions involve the development of atypical chromosomes, gonads, or hormones. The portion of the population that is intersex has been reported differently depending on which definition of intersex is used and which conditions are included. Estimates range from 0.018% (one in 5,500 births) to 1.7%. The difference centers on whether conditions in which chromosomal sex matches a phenotypic sex which is clearly identifiable as male or female, such as late onset congenital adrenal hyperplasia (1.5 percentage points) and Kline ...

Leydig Cell Hypoplasia
Leydig cell hypoplasia (or aplasia) (LCH), also known as Leydig cell agenesis, is a rare autosomal recessive genetic and endocrine syndrome affecting an estimated 1 in 1,000,000 individuals with XY chromosomes. It is characterized by an inability of the body to respond to luteinizing hormone (LH), a gonadotropin which is normally responsible for signaling Leydig cells of the testicles to produce testosterone and other androgen sex hormones. The condition manifests itself as pseudohermaphroditism (partially or fully underdeveloped genitalia), hypergonadotropic hypogonadism (decreased or lack of production of sex steroids by the gonads despite high circulating levels of gonadotropins), reduced or absent puberty (lack of development of secondary sexual characteristics, resulting in sexual infantilism if left untreated), and infertility. Leydig cell hypoplasia does not occur in people with XX chromosomes as they do not have either Leydig cells or testicles. However, the cause of the ...
