The net divides the court into two squares of nine metres by nine metres, and an attack line is drawn three metres back from the centre line, behind which a back-row player must take off when attacking.

William G. Morgan gave the game that name in 1895 because he had borrowed the net and the light ball from badminton, and only afterwards did a watching professor suggest volleyball, from the volleying of the ball back and forth over the net.

A Canadian physical instructor at the YMCA training school in Springfield, Massachusetts, he devised the game in 1891 to keep his class occupied indoors during a hard winter, nailed two peach baskets to the gallery railings and wrote thirteen rules, of which the ban on running with the ball survives…

The Palghat gap, about thirty kilometres wide in Palakkad district of Kerala, is the broadest break in the whole chain and carries the road and the railway line that join Coimbatore in Tamil Nadu to Palakkad and Thrissur in Kerala.

It was constituted under the Environment (Protection) Act to advise the central government on coastal matters and to work with the State and Union Territory Coastal Zone Management Authorities, which examine proposals and prepare the Coastal Zone Management Plans that draw the High Tide Line and the zone boundaries on…

That strategy asked that land falling within ten kilometres of the boundaries of National Parks and Wildlife Sanctuaries be notified as ecologically fragile, and the National Wildlife Action Plan carried the same thought forward, which is how the ten kilometre figure entered the discussion on Eco-Sensitive Zones.

The first Coastal Regulation Zone notification was issued in February 1991 under the Environment (Protection) Act, declaring the coastal stretches and the waters influenced by the tide as a regulated zone and classifying them for the first time.

Anamudi rises to 2,695 metres in the Anaimalai or Elephant hills of Idukki district in Kerala and is the highest point not only of the Western Ghats but of the whole of peninsular India, higher than anything south of the Himalayas.

Eco-Sensitive Zone notifications sort activities into three lists, and the permitted list encourages exactly these practices along with the agriculture and horticulture that local people already carry on, the use of renewable energy and the adoption of green technology, because the purpose of the zone is to limit damaging industry…

This category holds the ecologically sensitive stretches of the coast, and the notification lists mangroves, coral reefs and coral areas, sand dunes, salt marshes, mudflats, biologically active areas and the nesting grounds of turtles and birds in its sub-category CRZ-I-A, where construction is effectively barred.

The Coastal Regulation Zone notification fixes the landward limit of the regulated belt at 500 metres from the High Tide Line along the sea, and that figure has stayed the same through the notifications of 1991, 2011 and 2019.

The group that K. Kasturirangan headed reported in 2013 and used satellite imagery to separate the natural landscape of the Ghats from the cultivated and built-up land.

Its report of 2011 held that the whole range deserved protection and divided it into three graded zones, ESZ-1, ESZ-2 and ESZ-3, with the strictest ban on mining, quarrying and large projects in ESZ-1, and proposed a Western Ghats Ecology Authority to supervise the regime.

The Western Ghats were added to the World Heritage List in 2012 as a serial natural property, that is, a single listing made up of thirty-nine separate sites scattered through Kerala, Karnataka, Tamil Nadu and Maharashtra rather than one continuous block of land.

The Union Ministry of Environment, Forest and Climate Change notifies an Eco-Sensitive Zone using the power in Section 3(2)(v) of that Act, read with Rule 5(1) of the Environment (Protection) Rules, 1986, which lets the central government restrict industries and operations in an area it treats as fragile.

Apache Hive puts a table-like view over files stored in HDFS and lets an analyst write queries in HiveQL, a language close to SQL, which Hive then turns into jobs that run on the cluster, so that no Java programming is needed.

NoSQL databases drop the fixed table and row structure so that they can hold large and irregular data and spread it over many machines, and MongoDB is the best known document store, keeping records as documents in a format close to JSON.

Clustering is unsupervised because the data carries no labels: the algorithm itself groups similar records, k-means doing so by placing k centres and moving them until each record sits with its nearest centre.

ETL names the three steps through which data enters a warehouse: it is extracted from the operational systems that produced it, transformed so that formats, units, codes and duplicates are reconciled into one consistent shape, and then loaded into the warehouse tables.

It uses historical data with statistical models and machine learning to estimate what will probably happen next, such as which loan accounts are likely to slip into default or how much electricity a city will draw next summer.
