Quasi-periodic-scattering-problems
A new method for periodic scattering problems using 2nd kind boundary integral equations and the free-space Green s function, adding extra degrees of freedom on the unit cell walls, and imposing quasi-periodicity in an expanded linear system.(A new method for periodic scattering problems using 2nd kind boundary integral equations and the free-space Green s function, adding extra degrees of freedom on the unit cell walls, and imposing quasi-periodicity in an expanded linear system. This avoids the problems with the standard approach, namely: the quasi-periodic Green s function is slow to evaluate, it diverges at Wood s anomalies, and it does not handle large aspect ratios well. Our new approach cures all three issues, and can easily be `wrapped around an existing code (e.g. fast-multipole acceleration) for the isolated-obstacle scattering problem.
It includes the latest talk slides: "A new integral representation for quasi-periodic scattering problems in two dimensions")

LevelSet
VC++实现的GAC水平集, 这样的程序很少见,大部分都是matlab编写的,虽然程序比较简单,但是很有借鉴和参考价值。 有曲线演化的过程(GAC level set VC++ implemented, such programs are rare, and most of them are prepared matlab, although the procedure is relatively simple, but very useful reference and the reference value. Curve evolution process)

(书)现代通信系统使用MATLAB第二章(ALLIANCES is a recently proposed cooperative random access
protocol for wireless networks. In this paper we modify the
original model to include user location information. We also
derive pair-wise error probability (PEP) under Rayleigh flat
fading channel and a power-law attenuation environment.
Based on the PEP analysis we propose an optimal relay
selection scheme, which achieves significant throughput gains as
compared to the random relay selection scheme in the original
ALLIANCES.)
