... In this thesis we are concerned with the mathematical derivation of the solution of evolution problems arising from the study of the motion of charged or uncharged particles. In particular, the thesis is divided in two main subjects: the proofs of the existence and uniqueness proofs of the solution ...

... The purpose of the beam lift is to relocate the knife-edges to their proper positions on the bearing posts so that the front movable conductor will always be in the same vertical plane as the fixed conductor below it. Lifting the beam each time a weight is added or removed avoids the risk of jarring ...

Partial differential equation

In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. (A special case are ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives.) PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model.PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.
