These Simulink blocks contain transfer functions that model the pressure and flow transients for axisymmetric 2D viscous flow of a compressible fluid in a straight rigid circular cross section pipelines. Three models are available: (1) pressures at the ends (2) flow rates at the ends (3) pressure at one end and flow rate at the other Filtering is incorporated to reduce numerical oscillation (Gibbs phenomenon). See J. Dyn. Systems, Meas. & Control vol 122 (2000) pp. 153-162.

優(yōu)點:1.對于信噪比高的信號濾波效果好; % 2.對于邊沿的保護強過閾值濾波,不會產(chǎn)生閾值濾波情況下的過于平滑與Gibbs現(xiàn)象。 %缺點:1.由于對邊沿信號沒做任何處理,所以邊沿可能會有脈沖噪聲保留下來; % 2.計算相關(guān)系數(shù)中,如果計算出來的小波系數(shù)點位置偏差大,則相關(guān)系數(shù)計算受影響; % 3.需要迭代運算,迭代的噪聲能量閾值選取很重要,這里以開始段無信號處估計噪聲; % 4.需要迭代運算,所以運算量比閾值法大; % 5.受分解層次影響,在大尺度上小波系數(shù)點位置偏差更大,相關(guān)系數(shù)計算不準(zhǔn)確。 %需要具體調(diào)整的地方:1.分解的尺度;

The package includes 3 Matlab-interfaces to the c-code: 1. inference.m An interface to the full inference package, includes several methods for approximate inference: Loopy Belief Propagation, Generalized Belief Propagation, Mean-Field approximation, and 4 monte-carlo sampling methods (Metropolis, Gibbs, Wolff, Swendsen-Wang). Use "help inference" from Matlab to see all options for usage. 2. gbp_preprocess.m and gbp.m These 2 interfaces split Generalized Belief Propagation into the pre-process stage (gbp_preprocess.m) and the inference stage (gbp.m), so the user may use only one of them, or changing some parameters in between. Use "help gbp_preprocess" and "help gbp" from Matlab. 3. simulatedAnnealing.m An interface to the simulated-annealing c-code. This code uses Metropolis sampling method, the same one used for inference. Use "help simulatedAnnealing" from Matlab.
