Chemical reaction engineering for process optimization: the importance of primary processes on the molecular level

Any innovative design of a chem. or biol. reactor has to consider the dynamics of the primary phys. and chem. steps involved in the overall process. For homogeneous highly viscous systems the mixing time is of crucial importance for the product quality. In ...

Synchrotron radiation Imaging of internal structures in live animals

Giorgio Margaritondo

Ionizing radiation has long been used in medicine since the discovery of X-rays. Diagnostic imaging using synchrotron radiation has been under investigation since Rubenstein et al. reported dual-energy iodine-K-edge subtraction coronary angiography. Recent ...

How a Simple Shift Can Significantly Improve the Performance of Linear Interpolation

Michaël Unser, Philippe Thévenaz, Thierry Blu

We present a simple, original method to improve piecewise linear interpolation with uniform knots: We shift the sampling knots by a fixed amount, while enforcing the interpolation property. Thanks to a theoretical analysis, we determine the optimal shift t ...

A Systems Perspective on the Quality Description of Software Components

Alain Wegmann, Otto Preiss

In this paper we present our motivations for proposing of a generic model for the description of quality attributes of software artifacts, in particular suited to software components. The conceptual ideas for our quality description model are derived from ...

Towards a Composition Model Problem Based on IEC61850

Alain Wegmann, Otto Preiss

In order to define an interesting model problem for research work around the assembly of software components, this paper introduces the substation automation domain. Special emphasis is put on those aspects of the application area which make its employment ...

On Quality Attribute Based Software Engineering

Alain Wegmann, Otto Preiss

For a software system to be perceived as a success, or even just as properly functioning, many quality attributes, besides functionality, need to be at an acceptable level. However, current software development processes focus on the functional aspects of ...

Text Identification in Complex Background using SVM

Jean-Philippe Thiran, Hervé Bourlard, Datong Chen

This paper presents a fast and robust algorithm to identify text in image or video frames with complex backgrounds and compression effects. The algorithm first extracts the candidate text line on the basis of edge analysis, baseline location and heuristic ...

Design of High-Q Varactors for Low-Power Wireless Applications Using a Standard CMOS Process

Christian Enz

New applications such as wireless integrated network sensors (WINS) require radio-frequency transceivers consuming very little power compared to usual mainstream applications, while still working in the ultra-high-frequency range. For this kind of applicat ...

Regulation of a Connection Admission Control Algorithm

Jean-Yves Le Boudec, Patrick Thiran

Connection Admission Control (CAC) algorithms are used to decide whether an incoming connection should be accepted or rejected in a node of a network offering reservation based services in order to maintain the guaranteed Quality of Service (QoS) in the ne ...
