A series of new dispiro[fluorene-9',6,9'',12-indeno[1,2b]fluorenes] (DSF-IFs) has been synthesised. These new building blocks for blue-light-emitting devices and electroactive polymers combine indenofluorene (IF) and spirobifluorene (SBF) properties. We report here our synthetic investigations towards these new structures and their thermal, structural, photophysical and electrochemical properti...

A great deal of work has been carried out in the area of information modelling to support the sharing of information across participants in a construction project. Efforts in this area include projects such as ATLAS (Bohms et al., 1994) (for large scale engineering), COMBINE (Dubois et al., 1995) (for HVAC and building design), RATAS (Björk, 1994) and ICON (Aouad et al., 1995) (for building des...

This paper presents results from experiments performed with the COMBINE Interworking Unit, showing that good TCP performance is possible with the shaper size dimensioned to 2000 cells. The shaper itself had been dimensioned using a Poissonian packet arrival model, assuming that the notorious burstiness of data traffic was a problem for higher layer congestion control. These results verify the v...

Standards for data exchange are critical to the development of any field. They enable researchers and practitioners to transport information reliably, to apply a variety of tools to their problems, and to reproduce scientific results. Over the past two decades, a range of standards have been developed to facilitate the exchange and reuse of information in the domain of representation and modeli...

The share of common data, and the requirement to find faster and reliable ways for data flow within industrial environments and manufacturer-customer relationships has during the last decade raised a set of proposals seeking methodologies and architectures towards a potential solution. Most of them were developed within the R&D community with the support of industrial companies, as it is the ca...
