The performance of the new model was tested using two full-waveform data sets acquired by a Riegl LMS-Q680i laser scanner and an Optech Aquarius laser bathymeter, comparing with three classical waveform decomposition approaches: the Gaussian, generalized normal, and lognormal distribution-based ...
In this article, we develop an alternative method for fitting the SNMM by reformulating Ke and Wang芒聙聶s smoothing spline based model in terms of B-splines. The existing algorithm is based on a backfitting procedure that iterates between two mixed models whose corresponding likelihoods are ...
Wavelet transforms based on B-spline scaling functions are frequently used to obtain continuous surface- and volume representations at multiple levels of resolution. Starting with a fine-resolution data set, wavelet decomposition provides a ... M Bertram - Springer Berlin Heidelberg 被引量: 9发表: ...
We show the successful validation of the model by numerically reproducing a physical experiment by Gillham, Klute and Heermann (1976) describing primary drainage and imbibition in a vertical soil column. With a deviation of 3%, the simple Bézier-Spline-based model performs significantly better ...

The model generated is incorporated into a circuit simulator, which is used to perform large-signal transient and harmonic balance simulations. The transient I–V and gate charge extracted from the iso-thermal small-signal microwave Y-parameters, are in excellent agreement with the iso-thermal ...
This paper describes a probabilistic region-based deformable model using a new adaptive scheme for B-spline representation. The idea is to adapt the number of spline control points which are necessary to describe an object with complex shape. For this purpose, the curve segment length (CSL) is...
