Some international fuel card providers solely offer fuel cards for business fleets, others also for individuals. However, the system of fuel cards has meanwhile spread throughout Europe, where they are called cartões de combustivel, cartecarburanti, zakelijk tankpas, tankkaart, fleetpass, cartes de carburants, and Tankkarten.
Radius Limited is a fleet and mobility solutions provider with a focus on software and technology headquartered in Crewe, Cheshire. [ 2 ] [ 3 ] Established in 1990, Radius has a presence in 29 countries [ 3 ] and operates services across Telematics, Fuel Cards, Insurance, Vehicle Solutions, Telecoms and EV.
RADIUS is a client/server protocol that runs in the application layer, and can use either TCP or UDP. Network access servers, which control access to a network, usually contain a RADIUS client component that communicates with the RADIUS server. [1] RADIUS is often the back-end of choice for 802.1X authentication. [2]
The Schwarzschild radius was named after the German astronomer Karl Schwarzschild, who calculated this exact solution for the theory of general relativity in 1916. The Schwarzschild radius is given as =, where G is the gravitational constant, M is the object mass, and c is the speed of light.
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
This is the radius of the circle that the warhead has a 50 percent chance of falling into when aimed at the center. CEP is about 90–100 m for the Trident II and Peacekeeper missiles. [ 19 ]
The volume (V) and surface area (S) of a toroid are given by the following equations, where r is the radius of the circular section, and R is the radius of the overall shape. V = 2 π 2 r 2 R {\displaystyle V=2\pi ^{2}r^{2}R}
The radius of the largest ball about the origin in T p M that can be mapped diffeomorphically via exp p is called the injectivity radius of M at p. The cut locus of the exponential map is, roughly speaking, the set of all points where the exponential map fails to have a unique minimum.
