Critical point (network science). In network science, a critical point is a value of average degree, which separates random networks that have a  giant component from those that do not (i.e. it separates a network in a subcritical regime from one in a supercritical regime). Considering a random network with an average degree  the critical point is

where the average degree is defined by the fraction of the number of edges () and nodes () in the network, that is .

Subcritical regime 

In a subcritical regime the network has no giant component, only small clusters. In the special case of  the network is not connected at all. A random network is in a subcritical regime until the average degree exceeds the critical point, that is the network is in a subcritical regime as long as

.

Supercritical regime 

In a supercritical regime, in contrary to the subcritical regime the network has a giant component. In the special case of  the network is complete (see complete graph). A random network is in a supercritical regime if the average degree exceeds the critical point, that is if

.

Example on different regimes 

Consider a speed dating event as an example, with the participants as the nodes of the network. At the beginning of the event, people do not know anyone else. In this case the network is in a subcritical regime, that is, there is no giant component in the network (even if there are a couple of people, who know each other). After the first round of dates, everyone knows exactly one other person. There is still no giant component in the network, the average degree is , that is, everyone knows one other person on average, meaning that the network is at the critical point. After the second round, the average degree of the network exceeds the critical point, and the giant component is present. In this specific case, the average degree is . The network is in a supercritical regime.

Ángel Gallardo (civil engineer). Ángel Gallardo (19 November 1867, in Buenos Aires – 13 May 1934, in Buenos Aires) was an Argentine civil engineer, natural scientist and politician. He served variously as the president of the National Council of Education, the Minister of Foreign Affairs and the Rector of the University of Buenos Aires. He was recognised for his scientific work both in Argentina and abroad.

Gallardo's scientific work dealt with problems of heredity and cell division.

Early life
He graduated from the Colegio Nacional de Buenos Aires in 1887 and received his degree in civil engineering from Facultad de Ciencias Exactas y Naturales (UBA) of the University of Buenos Aires in 1894. However, in addition to civil engineering, beginning in 1892 he studied natural history (biology) under Carlos Berg at the Bernardino Rivadavia Natural Sciences Museum.

A street in Buenos Aires is named after him.

In 1916, botanist Cristóbal Mariá Hicken (1875-1933), named a species of plant from Argentina, after him, Gallardoa.

The Nightmare of the Vultures. The Nightmare of the Vultures () is a documentary of drones and a simulated drone attack  that was shown Iranian state TV on 7 February 2014. The film gives a short history of the Iranian drone program, and depicts a simulated military counterattack against Israeli targets and American installations in the Persian Gulf. Iranian drones and missiles are shown bombarding Tel Aviv’s Kikar Hamedina square, Azrieli Towers skyscrapers, IDF’s The Kirya central command complex, Ben Gurion International Airport, Haifa's Technion, nuclear reactor in Dimona, and several air force bases. In the film, Ali Khamenei, Supreme leader of Iran, states that Iranian drones and missiles are used just for defense against our enemies.

Content 
Iranian advancement in the field of drone production is discussed. In particular,  (Mohajer, Mohajer 4, Ababil 1, Ababil 2, Karrar) are shown to be developed by Iranian scientist.

Set to background music, the video begins with Ayatollah Ali Khamenei giving a speech to military graduates. Iran's drones are shown to evade Israel's Iron Dome systems of Tel Aviv and Haifa and Iranian missiles fall on the square Kikar Hamedina square, the Azrieli Towers, the Kirya (Israeli military control complex) and Ben Gurion International Airport, the Technion in Haifa, Ariha missile launch base, Zalim military base, Palmachim air base, War ministry building, Dimona nuclear reactor. The film then depicts Iranian drones launching missiles and destroying the USS Abraham Lincoln in the Persian Gulf as well as American military jets and helicopters taking off from the vessel.

Suanite. Suanite is a magnesium borate mineral with formula Mg2B2O5.

It was first described in 1953 by Japanese scientist Takeo Watanabe from the University of Tokyo. 
His first contact with the mineral was during analysis of gold- and copper- bearing skarn minerals from the Hol Kol mine, located in North Korea obtained in 1939. Due to the small sample size available to him, he was only able to determine the unknown substance's optical properties under a microscope. Watanabe was able to return to the site in 1943 and obtain further samples that permitted him to perform chemical analysis on the material.

CNOOC Building. The CNOOC Headquarters Building () is located on the Second Ring Road in the Chaoyangmen neighborhood of Beijing's Dongcheng District. It is the corporate headquarters for the China National Offshore Oil Corporation, one of the country's two state-owned oil companies. It was designed by the New York architectural firm of Kohn Pedersen Fox (KPF) and opened in 2006.

Design
According to KPF, aspects of the building's design are meant to evoke the petroleum industry. It is in the shape of a triangle with rounded corners, gently flaring outward, as to suggest the prow of an oil tanker. At its base level, the building is supported by piloti, suggesting the offshore oil derricks that are the company's primary source of product. The grounds are also landscaped to suggest the surface of the ocean.

The building is meant to be a counterpart to the large Ministry of Foreign Affairs building on the opposite corner of the intersection of the Second Ring Road and Chaoyangmen Street. Inside it has a central atrium lit by an upper clerestory. Sky gardens around the atrium are meant to facilitate impromptu, informal meetings between employees. Outside, a western courtyard, buffered from the busy street by a three-story L-shaped podium and entered through an oversize gateway, is meant to invite visitors to explore the building.

Local reaction to the building has seen it differently. Many residents thought that, instead of resembling a ship or an oil derrick, the building looked like a toilet bowl, particularly a model without a tank then being marketed in China by Kohler. A local advertiser later erected a billboard promoting that toilet atop a building across the Ring Road.

Snowspeed. Snowspeed  is a gravity powered snow sledge that has been designed to beat the world speed record.

Its design deliberately resembles Formula 1 racing cars because this will help it achieve speeds of up to 250 km/h (155 mph).

The current speed record is held by Guy Martin, who achieved 134.36 km/h (83.49 mph) in 2014.

The sledge has been created by a team of Norwegian speed enthusiasts, led by designer Nima Shahinian, journalist Jorn Madslien and entrepreneur Tom Ruud.

Tests have been carried out at [Toyota Motorsport GmbH] - TMG, the current second-best endurance motor racing team in the world.

Early tests revealed that the Snowspeed prototype III design needed a bit more rear-end stability, and those adjustments are the team's focus during 2016, before an attempt on the record is due to be made towards the end of winter 2017.

ATM-grade. In Air Traffic Management, "ATM-grade" or "ATM grade" defines a system or solution that fulfills certain requirements so that it can be used within the Air Traffic Management environment. 
Those requirements cover for example aspects of
 reliability: certain applications require "six nines" availability. An ATM-grade solution has to offer end-to-end availability of up to at least 99,9999% availability.
 well tested and documented: the European Air Traffic Management industry requires equipment to be developed according to specific standards and guidelines (e.g., ED-153) that allow a safety certification. Therefore, an ATM-grade solution needs to be implemented according to ED-153.

The term has been coined by EUROCONTROL to clearly state the advanced requirements of Air Traffic Management to ensure flight safety.

Sky Gate Bridge R. , also known as the , serves as a link between the mainland of Osaka, Japan to the artificial island in Osaka Bay on which Kansai International Airport is built. It is the longest double-decked truss bridge in the world. The bridge carries six lanes of automobile traffic on top and two of rail below, over nine truss spans.

Structural specifications
The Sky Gate Bridge is a continuous truss bridge that measures  long,  wide (6 lanes), and  at its highest point in the center.

History
The bridge commenced construction in June 1987, and was completed in March 1994. On 21 April 2009, management of the expressway portion of the bridge was handed over to the West Nippon Expressway Company. This expressway was numbered E71 alongside the Kansai-Kūkō Expressway in 2016.

Typhoon Jebi
The bridge was damaged on 4 September 2018 by Typhoon Jebi. A 2600-ton tanker lost power and was blown into one side, severely damaging half of the automobile lanes and the rail lines. The bridge, being the sole link between the airport and the mainland, stranded approximately  passengers and  staff overnight at the airport. They were evacuated the next day via the  ferry to nearby Kobe Airport, later joined by buses over the undamaged half of the bridge.
The bridge was partially reopened to vehicle traffic on 7 March 2019 with four lanes open. The bridge's full capacity with six lanes of traffic was restored on 8 April 2019.

Junction list
The entire expressway is in Osaka Prefecture. The sequence of kilometer posts continue from the Kansai-Kūkō Expressway.

Metocean. In offshore and coastal engineering, metocean refers to the syllabic abbreviation of meteorology and (physical) oceanography.

Metocean study
In various stages of an offshore or coastal engineering project a metocean study will be undertaken. This, in order to estimate the environmental conditions of direct influence on the choices to be made during the project phase at hand, and to arrive at an effective and efficient solution for the problems/goals stated. In later phases of a project, more detailed and thorough metocean studies may be needed, depending on whether there is an expected additional gain with respect to the successful and efficient completion of the project.

Metocean conditions
Metocean conditions refer to the combined wind, wave and climate (etc.) conditions as found on a certain location. They are most often presented as statistics, including seasonal variations, scatter tables, wind roses and probability of exceedance. The metocean conditions may include, depending on the project and its location, statistics on:
Meteorology 
 wind speed, direction, gustiness, wind rose and wind spectrum
 air temperature
 humidity  
 occurrence and strength of typhoons, hurricanes and (other) cyclones 

Physical oceanography
 water level fluctuations
 historical, expected and seasonal sea level changes
 storm surges
 tides
 tsunamis
 seiches
 wind waves – wind seas and swells – characterised by statistics like: significant wave heights and periods, propagation directions and (directional) spectra
 bathymetry
 salinity, temperature and other constituents
 stratification, density-driven currents and internal waves
 ice occurrence, extent, thickness, strength and seabed gouging

Metocean data

The metocean conditions are preferably based on metocean data, which can come from measuring instruments deployed in or near the project area, global (re-analysis) models and remote sensing (often by satellites). For estimating probabilities of exceedance – for relevant physical quantities – data of extreme events during more than one year is needed.

By use of validated numerical models, the availability of metocean data can be extended. For instance, consider the case of a coastal location where no wave measurements are available. If there is long-term wave data available in a nearby offshore location (e.g. from satellites), a wind wave model can be employed to transform the offshore wave statistics to the nearshore location (provided the bathymetry is known).

Often, long-term local measurements of wave conditions due to extreme events (e.g. hurricanes) are missing. By using estimates for the wind fields during past extreme events, the corresponding wave conditions can be computed through wave hindcasts.
