Humphrey field analyser ( HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. [1] The results of the analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease ...
In the context of chemistry, molecular physics, physical chemistry, and molecular modelling, a force field is a computational model that is used to describe the forces between atoms (or collections of atoms) within molecules or between molecules as well as in crystals. Force fields are a variety of interatomic potentials.
A virtual particle is a theoretical transient particle that exhibits some of the characteristics of an ordinary particle, while having its existence limited by the uncertainty principle, which allows the virtual particles to spontaneously emerge from vacuum at short time and space ranges. [1] The concept of virtual particles arises in the ...
Virtual work is the total work done by the applied forces and the inertial forces of a mechanical system as it moves through a set of virtual displacements. When considering forces applied to a body in static equilibrium, the principle of least action requires the virtual work of these forces to be zero. Mathematical treatment
In physics and engineering, heat flux or thermal flux, sometimes also referred to as heat flux density [1], heat-flow density or heat-flow rate intensity, is a flow of energy per unit area per unit time. Its SI units are watts per square metre (W/m 2 ). It has both a direction and a magnitude, and so it is a vector quantity.
Virtual photons are responsible for Lamb shift, which is a small shift in the energy levels of hydrogen atoms caused by the interaction of the atom with virtual photons in the vacuum. They are also responsible for the Casimir effect , which is the phenomenon of two uncharged metallic plates being attracted to each other due to the presence of ...
Definition. The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature ( STP) is defined as 0 Hounsfield units (HU), while the radiodensity of air at STP is defined as −1000 HU.
The game was released on the 3DS via the Virtual Console in Japan on August 8, 2012 and was released in Europe and North America on February 7, 2013. Mega Man 2 was novelized in the Worlds of Power series published by Scholastic in 1990. The novel mostly follows the game, even offering game hints at the end of some chapters.
