Ritt - Wu ’ s Decomposition Algorithm ∗
An improved Ritt-Wu’s decomposition (of an algebraic set into the union of irreducible varieties) algorithm is given. The algorithm has been used to prove geometric theorems that Wu’s original method addresses. Unlike Wu’s original approach, nondegenerate conditions are given explicitly at the beginning, not generated during the proof process. A program based on this improved version of the alg...

as good as his little sister Maria. He does nothing but play marbles. I can't even send him to the store because he never brings home what I tell him to." The general tenor of this dissertation was repeated every time I saw her in the future. I devoted my first lesson to letting Joseph read the story of The Little Red Hen, pp. 1-9, Winston Primer. He read with great difficulty, spelling the wor...
متن کاملDesign formulas for short - wavelength FELs
Simple formulas for optimization of VUV and X-ray SASE FELs are presented. The FEL gain length and the optimal beta-function are explicitly expressed in terms of the electron beam and undulator parameters. The FEL saturation length is estimated taking into account quantum diffusion in the undulator. Examples of the FEL optimization are given. Parameters of a SASE FEL, operating at the Compton w...

The finite difference method represents a highly straightforward and logical approach to approximating continuous problems using discrete methods. At its heart is a simple idea: substitute finite, discrete differences for derivatives in some way appropriate for a given problem, make the time and space steps the right size, run the difference method, and get an approximation of the answer. Many ...
متن کاملDESIGN CONSIDERATIONS FOR TABLE-TOP FELs∗
Refinements in laser technology (few-cycle pulse generation, chirped pulse amplification) combined with supercomputer-based plasma simulations have brought the discipline of relativistic laser-matter interaction to a new level of predictability. This was recently demonstrated by the generation of brilliant electron bunches with energies on the 0.1-1-GeV-scale. Our plan is to utilize such lasera...
