Remarks on the travelling wave decomposition

Watching a Travelling Wave Watching a Travelling Wave

Travelling waves are a feature of many spatio-temporal series. The use of single side band filtering and the complex singular value decomposition to isolate such waves is described. As with other applications of the singular value decomposition, such as principal components, the results can be difficult to interpret. In the case of travelling waves, however, a dynamic graphical display using co...

Remarks on Lewenstein-Sanpera Decomposition

We discuss in this letter Lewenstein-Sanpera (L-S) decomposition for a specific Werner state. Compared with the optimal case, we propose a quasi-optimal one which in the view of concurrence leads to the same entanglement measure for the entangled mixed state discussed. We think that in order to obtain entanglement of given state the optimal L-S decomposition is not necessary. ∗Email: shmj@ustc....

Travelling Wave Linear Accelerators

Communicated b y y. D. Cockcroft; MS. ABSTRACT. Acceleration of electrons by means of an electroma,onetiic wave travelling down a circular corrugated tube is considered. The relevint properties of corrugated tubes are derived and the factors influencing electron enxgies. Some numerical results are also quoted for a wavelength of 10 cm. The problems of high energy accelerators arc &scussed brief...

On travelling wave solutions of the diffusive Leslie-Gower model

We investigate the diffusive Leslie–Gower predator–prey model. Travelling wave solutions were found and a minimum wave speed relationship was derived. Linear stability analysis was performed in addition to full numerical simulation of the model. All travelling waves were found to be stable. © 2015 Elsevier Inc. All rights reserved.
