Base942MontVerdun
There are many different numeral systems, that is, writing systems for expressing numbers. By culture / time period "A ''base'' is a natural number B whose ''powers'' (B multiplied by itself some number of times) are specially designated within a numerical system." The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. Some systems have two bases, a smaller (subbase) and a larger (base); an example is Roman numerals, which are organized by fives (V=5, L=50, D=500, the subbase) and tens (X=10, C=100, M=1,000, the base). By type of notation Numeral systems are classified here as to whether they use positional notation (also known as place-value notation), and further categorized by radix or base. Standard positional numeral systems The common names are derived Hexadecimal#Etymology, somewhat arbitrarily from a mix of Latin and Greek language, Greek, in some cases incl ...

Air Command And Control System
Air Command and Control System (ACCS) is the NATO project planned to replace the NATO Air Command and Control Systems of the 1990s. At the highest level it comprised the Combined Air Operations Centre (CAOC) from which the air battle is run. Beneath this level of command is the Air Control Centre (ACC), Recognized Air Picture (RAP) Production Centre (RPC) and Sensor Fusion Post (SFP) combined in one entity called ARS. The ARS is the equivalent to the Control and Reporting Centers (CRCs) operated in the 1990s. The ACCS project comprised both static and deployable elements. Under separate funding, NATO intended to procure deployable sensors for the deployable ACCS component (DAC). Oversight of the project is provided by the NATO Communications and Information Agency (NCIA) in Brussels, Belgium. Until 2012, this was executed by the NATO ACCS Management Organisation (NACMA) Board of Directors, senior representatives of the Nations engaged in the NATO ACCS project. The Board is respo ...

Continuity Of Government
Continuity of government (COG) is the principle of establishing defined procedures that allow a government to continue its essential operations in case of a catastrophic event such as nuclear war. Continuity of government was developed by the British government before and during World War II to counter threats, such as that of the ''Luftwaffe'' bombing during the Battle of Britain. The need for continuity of government plans gained new urgency with nuclear proliferation. During and after the Cold War countries developed such plans to avoid (or minimize) confusion and disorder due to a power vacuum in the aftermath of a nuclear attack. In the US, COG is no longer limited to nuclear emergencies; the Continuity of Operations Plan was activated following the September 11 attacks. By country Australia During the years following the federation of Australia in 1901, several locations were considered for the national capital. One of the criteria used to assess sites was that they ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Management In France
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, he ...

Nuclear Command And Control
Nuclear command and control (NC2) is the command and control of nuclear weapons. The U. S. military's ''Nuclear Matters Handbook 2015'' defined it as the "activities, processes, and procedures performed by appropriate military commanders and support personnel that, through the chain of command, allow for senior-level decisions on nuclear weapons employment." The current ''Nuclear Matters Handbook 2020 evised' defines it as "the exercise of authority and direction, through established command lines, over nuclear weapon operations by the President as the chief executive and head of state." United States In the United States, leadership decisions are communicated to the nuclear forces via an intricate Nuclear Command and Control System (NCCS). The NCCS provides the President of the United States with the means to authorize the use of nuclear weapons in a crisis and to prevent unauthorized or accidental use. It is an essential element to ensure crisis stability, deter attack aga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
