Reconstruction of ion temperature profiles from single chord NPA measurements on the TCV tokamak

Basil Duval, Alexander Karpushov, Christian Schlatter

The flux of charge exchange ( CX) neutrals measured by neutral particle analysers ( NPAs) is the line integral along the viewline of the NPA and contains information about the ion energy distribution of the observed plasma. On the Tokamaka a Configuration ...

Quantitative analysis of X-band weather radar attenuation correction accuracy

Alexis Berne

At short wavelengths, especially C-, X-, and K-band, weather radar signals are attenuated by the precipitation along their paths. This constitutes a major source of error for radar rainfall estimation, in particular for intense precipitation. A recently de ...

Multiple functions of Notch signaling in self-renewing organs and cancer

Freddy Radtke, Anne Wilson

In recent years a substantial body of evidence has accumulated to support the notion that signaling pathways known to be important during embryonic development play important roles in regulating self-renewing tissues. Moreover, the same pathways are often ...

Discovering Coherent Biclusters from Gene Expression Data Using Zero-Suppressed Binary Decision Diagrams

Giovanni De Micheli, Luca Benini

The biclustering method can be a very useful analysis tool when some genes have multiple functions and experimental conditions are diverse in gene expression measurement. This is because the biclustering approach, in contrast to the conventional clustering ...

Submicron periodic poling and chemical patterning of GaN

Nicolas Grandjean

Periodic polarity (PePo) GaN films are grown by molecular-beam epitaxy. A high Mg doping is used to reverse the film polarity from Ga to N. An etching step is then performed to define the PePo pattern. Ultrasharp inversion domain boundaries between Ga- and ...

Cast shadow segmentation using invariant colour features

Touradj Ebrahimi, Elena Salvador

Shadows are integral parts of natural scenes and one of the elements contributing to naturalness of synthetic scenes. In many image analysis and interpretation applications, shadows interfere with fundamental tasks such as object extraction and description ...

Efficient Energies and Algorithms for Parametric Snakes

Michaël Unser, Thierry Blu, Mathews Jacob

Parametric active contour models are one of the preferred approaches for image segmentation because of their computational efficiency and simplicity. However, they have a few drawbacks which limit their performance. In this paper, we identify some of these ...

Polyharmonic Smoothing Splines for Multi-Dimensional Signals with 1 ⁄ $ ||ω|| ^{ \tau } $ -Like Spectra

Michaël Unser, Dimitri Nestor Alice Van De Ville

Motivated by the fractal-like behavior of natural images, we propose a new smoothing technique that uses a regularization functional which is a fractional iterate of the Laplacian. This type of functional has previously been introduced by Duchon in the con ...

Cast Shadow Recognition in Color Images

Touradj Ebrahimi, Elena Salvador

Shadows are often integral parts of natural scenes and their identification is an important task in image analysis. In this paper, we propose an algorithm for recognition of shadows cast by objects on the scene's background. The proposed approach is based ...

An integral characterization of Hajlasz-Sobolev space

Marc Troyanov

We prove that the pointwise inequality used by P. Hajlasz in his definition of Sobolev spaces on metric spaces is equivalent to an integral (Poincaré-type) inequality. ...
