Catechol functionalized polymers and method for preparing them

Described are compounds that are capable of forming adlayers, said compounds comprising at least one headgroup A, an optional linker B, a polymer C, a terminal group D and an optionally present crosslinking group R, wherein the headgroup A is a compound of ...

Laplacian Operator, Diffusion Flow and Active Contour on non-Euclidean Images

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson, Iva Bogdanova Vandergheynst

We propose here some basic approaches to direct processing of the

-images as we take into consideration the geometry of each one. Obviously, the geometry of each of these images is a consequence of the geometry of the sensor's mirror used. This tech ...

Lead (Pb) exposure and its effect on APP proteolysis and Abeta aggregation

Hilal Lashuel

Alzheimer's disease (AD) is a progressive neurodegenerative disorder with clinical manifestations appearing in old age, however, the initial stages of this disease may begin early in life. AD is characterized by the presence of excessive deposits of aggreg ...

Anisotropic error estimates for elliptic problems

Luca Formaggia

Moving from the anisotropic interpolation error estimates derived in Formaggia and Perotto, (2001), we provide here both a-priori and a-posteriori estimates for a generic elliptic problem. The a-priori result is deduced by following the standard finite ele ...

Optimum error nonlinearities for long adaptive filters

Ali H. Sayed

In this paper, we consider the class of adaptive filters with error nonlinearities. In particular, we derive an expression for the optimum nonlinearity that minimizes the steady-state error and attains the limit mandated by the Cramer-Rae bound of the unde ...

Development of a multiwavelength aerosol and water-vapor lidar at the Jungfraujoch Alpine Station (3580 m above sea level) in Switzerland

Hubert van den Bergh, Bertrand Calpini, Valentin Simeonov, Ioan Balin, Gilles Larchevêque, Remo Nessler

The Jungfraujoch Research Station (46.55 degrees N, 7.98 degrees E, 3580 m above sea level) for decades has contributed in a significant manner to the systematic observation of the Earth's atmosphere both with in situ measurements and with trace gas column ...

A one-dimensional model for blood flow: Application to vascular prosthesis

Alfio Quarteroni, Fabio Nobile, Luca Formaggia

We investigate a one-dimensional model of blood flow in human arteries. In particular, we consider the case when an abrupt variation of mechanical characteristic of artery is caused by the presence of a vascular prosthesis. The derivations of the model and ...

Extended fast fixed order RLS adaptive filters

Ali H. Sayed, Ricardo Merched

The existing derivations of conventional fast RLS adaptive filters are intrinsically dependent on the shift structure in the input regression vectors. This structure arises when a tapped-delay line (FIR) filter is used as a modeling filter. We show, unlike ...

Frequency response identification of the dynamics of a Tokamak plasma

Jonathan Bryan Lister

In this paper we describe the application of an H-infinity system identification procedure to a Tokamak. The work is motivated by the need to create linear models which are suitable for controller design and which may be used to validate different models d ...

ASYMMETRIC FILTER FOR TEXT RECOGNITION IN VIDEO

Datong Chen

Stripes are a common sub-structure of text characters, and the scale of the stripes does not vary significantly within a character. In this paper a new form of filter is derived from the Gabor filter which can efficiently estimate the scales of such stripe ...
