We present a method for improving robustness in feature-based tracking of human motion. Motion flows of features estimated by a standard tracker are modified to be coherent with neighboring ones. This coherence constraint is computed based on a smooth appr ...
The electropolishing of a B-doped diamond (BDD) film deposited by CVD was studied in HOAc-H2SO4 media. The electropolished surface was characterized by SEM, XPS, and electrochem. measurements. In 1 M H2SO4 no polishing of the surface occurred even after pr ...
The problem of reconstructing an unknown signal from n noisy samples can be addressed by means of non- parametric estimation techniques such as Tikhonov reg- ularization, Bayesian regression and state-space fixed- interval smoothing. The practical use of t ...
Endosseous implant to be applied to a human or animal bone, said implant having a smooth or rough surface texture and wherein said surface has been treated with at least one organic compound carrying at least one phosphonic acid group or a salt thereof and ...

In the present paper, the problem of selecting priors for continuous-time processes is approached using the MaxEnt paradigm. First, assuming stationarity and Gaussianity, a suitable definition of differential entropy rate is introduced. Second, it is obser ...
The electrostatic interpretation of the Jacobi-Gauss quadrature points is exploited to obtain interpolation points suitable for approximation of smooth functions defined on a simplex. Moreover, several new estimates, based on extensive numerical studies, f ...

Differential photoluminescence excitation (DPLE) spectroscopy is shown to be an efficient way to measure gain and absorption spectra of excited semiconductors. Very small excited volumes can be probed, and thus DPLE spectroscopy is ideal to probe nanostruc ...
We present three operators for the expression of event-based large-scale distributed programming. In short, these operators support a publish/subscribe-based interaction scheme, leading to a distributed object programming model merging the benefits of obje ...
The ternary sulfide Ag7TaS6 displays high Ag-ion conductivity at ambient temperature, and the framework TaS6 and Ag ions can be respectively regarded as the host structure and guest ions. Two low-temperature phases, i.e. Ag7TaS6 II and Ag7TaS6 III, were fo ...
Estimates of transfer functions from measurements contain undesired information -- noise -- whose effect can partly be taken away by applying different smoothing techniques. One such smoothing technique suggests to remove the noise by gating the impulse re ...
