Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
The Eurofighter Typhoon is a European multinational twin-engine, supersonic, canard delta wing, multirole fighter. [3] [4] The Typhoon was designed originally as an air-superiority fighter [5] and is manufactured by a consortium of Airbus, BAE Systems and Leonardo that conducts the majority of the project through a joint holding company, Eurofighter Jagdflugzeug GmbH.
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
The Palermo Technical Impact Hazard Scale is a logarithmic scale used by astronomers to rate the potential hazard of impact of a near-Earth object (NEO). It combines two types of data — probability of impact and estimated kinetic yield—into a single "hazard" value.
This greatly expanded the utility of the product in simulating long international flights as well as instrument-based flight relying on radio navigation aids. Some of these airports, along with additional objects such as radio towers and other "hazard" structures, were built from publicly available U.S. government databases.
Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American anti-ballistic missile defense system designed to intercept and destroy short-, medium-, and intermediate-range ballistic missiles in their terminal phase (descent or reentry).
A USGS model image shows the enormous atmospheric river that may have been present during the 1861–1862 flood event.. The ARkStorm (for Atmospheric River 1,000) is a hypothetical megastorm, whose proposal is based on repeated historical occurrences of atmospheric rivers and other major rain events first developed and published by the Multi-Hazards Demonstration Project (MHDP) of the United ...
A propane tank car after a fire, the HAZMAT 1075 symbol can be seen in red as a warning of the danger posed by the gas. A gas is a substance which (a) at 50 °C (122 °F) has a vapor pressure greater than 300 kPa (43.51 PSI) or
