Electron and positron spectra in three-dimensional spatial-dependent propagation model

Three - Dimensional Propagation Algorithm

Depth image based rendering (DIBR) is the process of synthesizing new “virtual” views from a set of “real” views which include color and depth images. Because of its photorealism and less stringent computational requirement, DIBR has many applications such as 3D TV, remote reality, and video conferencing, and has become one of the hot research areas in visual computing in recent years. Since th...

Three-dimensional, Time-dependent Simulation of Free- Electron Lasers

Simulation codes modeling the interaction of electrons with an optical field inside an undulator are an essential tool for understanding and designing free-electron lasers (FELs). A new code under development, named MINERVA, uses a modal expansion for the optical field. A Gaussian expansion is used for free-space propagation, and an expansion in waveguide modes for fully guided propagation, or ...

Inverse Sturm--Liouville problems using three spectra with finite number of transmissions and parameter dependent conditions

‎In this manuscript‎, ‎we study various by uniqueness results for inverse spectral problems of Sturm--Liouville operators using three spectrum with a finite number of discontinuities at interior points which we impose the usual transmission conditions‎. ‎We consider both the cases of classical Robin and eigenparameter dependent boundary conditions.

Three-dimensional model of electron beam generated plasma

A three-dimensional model for magnetized electron beam generated plasma is described, which includes a coupled fluid simulation of the bulk plasma and a Monte Carlo model for beam electrons. A modified form of the classical expressions for magnetized-plasma electron transport coefficients is used in the fluid plasma model. The plasma model is calibrated and validated using Langmuir probe measur...
