We discuss the main stages of development of the error calculation since the beginning of XIX-th century by insisting on what prefigures the use of Dirichlet forms and emphasizing the mathematical properties that make the use of Dirichlet forms more relevant and efficient. The purpose of the paper is mainly to clarify the concepts. We also indicate some possible future research.

Teaching and promoting conceptual thinking in engineering education is challenging. Two recently introduced design thinking models are compared in order to explore the reasons behind this challenge. The comparison results in key distinctions between divergent and convergent thinking, and between concept and knowledge domains. The differentiating principle is shown to be a common principle of th...

Background Numerous anomalies of cardiac venous system prevent optimal endovascular implantation of LV lead in more than 15% of patients with heart failure and indications for Coronary Resynchronization Therapy (CRT). Insisting on endovenous approach in these patients can be one of the potentional reasons for large number of nonresponders reported in the literature. Purpose of this study was to...

The family of Toll-like receptors plays an essential role in the induction of the immune response. These receptors sense the presence of microbial ligands and activate the nuclear factor-κB transcription factor. We review the key studies that led from the formulation of the concept of pattern recognition receptors to the characterization of Toll-like receptors, insisting on the important role p...

We adress the problem of Fock space representations of (free) multiplet component fiels encountered in supersymmetric quantum field theory insisting on positivity and causality. We look in detail on the scalar and Majorana components of the chiral supersymmetric multiplet. Several Fock space representations are introduced. The last section contains a short application to the supersymmetric Epst...

The desideratum of semantic interoperability has been intensively discussed in medical informatics circles in recent years. Originally it was assumed by many that this issue could be addressed simply by insisting on the application of shared clinical terminologies. More recently however the use of the term ‘ontology’ has been steadily growing. We here address the issue of the degree to which th...

Technical integration The need for technical integration is quite important. The technical compatibility should be in place for the whole range of tools for translation translation memory, machine translation and term bases. It is the responsibility of the vendors to ensure compatibility by applying standards. Official standards being scarce, pragmatic standards should be agreed upon and adhere...

The climate change discussion in the framework of the Kyoto protocol has clearly emphasized the need for reliable methods to value projects targeted on reduction of greenhouse gases. Moreover, the recent carbon price development in the mandatory EU Emission Trading Scheme exhibits the insisting importance of accurate risk management when business is exposed to greenhouse gas emissions. In this ...

We study the Renormalization Group (RG) evolution of the couplings in a model with a real SU(2) triplet in the Higgs sector. Insisting that the model remain valid up to 1 TeV we show that it is possible for there to be no light Higgs bosons without any otherwise dramatic deviation from the physics of the Standard Model.
