A total asymmetric synthesis of the polyol subunit of the polyene macrolide antibiotic RK-397 was developed through the stereoselective functionalization of (1R,1’S,6S,6’R)-3,3’-methylenebis(cyclohept-3-ene-1,6-diol). The pathway generates a large variety ...
This research work falls on a multidisciplinary domain, where there is a cross feeding between Computer, Information Sciences and Cognitive Sciences. This PhD dissertation has focused on the interaction and collaboration issues in Web-based experimentation ...
A focus/detector system of an X-ray apparatus and a method for generating projective or tomographic phase contrast recordings, are disclosed. In an embodiment of the system, the system includes a beam source equipped with a focus and a focus-side source gr ...
New pathways toward the synthesis of polyketide-like macrolides have been developed through the functionalization of long chain polyolic fragments readily obtained from 3,3'-methylenebis{[6-(benzyloxy)methoxy]cyclohept-3-en-1-ol} derivatives 6. This synthe ...
In this paper we show that the Ate pairing, originally defined for elliptic curves, generalises to hyperelliptic curves and in fact to arbitrary algebraic curves. It has the following surprising properties: The loop length in Miller’s algorithm can be up t ...
Analysing and optimising electromagnetic structures like filters, multiplexers, printed circuits and antennas etc. demand for electromagnetic CAD tools to be accurate and fast at the same time. In very rare cases a closed form (approximate) solution of the ...
This paper introduces a framework for real-time simulation and rendering of crowds navigating in a virtual environment. The solution first consists in a specific environment preprocessing technique giving rise to navigation graphs, which are then used by t ...

In today's network world, advancement in new product development (NPD) is being driven by different types of networks, joint ventures, alliances, outsourcing and mergers. These business trends have resulted in complex organisations and development projects ...
The use of numerical procedure at a level never reach so far in optical imaging enables DHM to overcome two cumbersome alignment procedures of interferometric microscopes: (1) fine focus of the sample, and (2) sample tilt adjustment. In addition the techno ...
We present a new method for signal reconstruction from multiple sets of samples with unknown offsets. We rewrite the reconstruction problem as a set of polynomial equations in the unknown signal parameters and the offsets between the sets of samples. Then, ...
