a sign convention is a choice of the physical significance of signs (plus or minus) for a set of quantities, in a case where the choice of sign is arbitrary...

In electrical engineering, the passive sign convention (PSC) is a sign convention or arbitrary standard rule adopted universally by the electrical engineering...

The cash flow sign convention is that money you pay out has a minus sign, while money you take in has a plus sign (or no sign). Most financial calculators...

In mathematics, the sign of a real number is its property of being either positive, negative, or 0. Depending on local conventions, zero may be considered...

engineering mechanics sign convention for the physical space and the alternative sign convention for the Mohr-circle space (sign convention #3 in Figure 5)...

white stop legend. The European Annex to the convention also allows the background to be "light yellow". Sign B2b is a red circle with a red inverted triangle...

computation of bending moments can be confusing because of unexplained sign conventions and implicit assumptions. The descriptions below use vector mechanics...

curvature is infinite. This convention is used in this article. Other conventions such as the Cartesian sign convention change the form of the equations...

Radius of curvature (ROC) has specific meaning and sign convention in optical design. A spherical lens or mirror surface has a center of curvature located...

sources have negative power consumption. This is called the passive sign convention. In the case of resistive (Ohmic, or linear) loads, the power formula...

arbitrary sign of the quantum number match the sign of the particles' electric charges. When following the electric-charge-sign convention, the lepton...

(with a sign convention of m 1 > m 2 {\displaystyle m_{1}>m_{2}} ) derive a system of equations for the acceleration (a). As a sign convention, assume...

the Condon–Shortley and Wigner sign convention as discussed by Baird and Biedenharn. Tables with the same sign convention may be found in the Particle Data...

if concave. Sign conventions vary between different authors, which results in different forms of these equations depending on the convention used. For a...

This article uses the physics sign convention for work, where positive work is work done by the system. Using this convention, by the first law of thermodynamics...
