There have been attempts made by several organizations, nations and states to take leverage of Information Technology’s ever expanding application-spectrum. These deliberate attempts are Information Technology Initiatives or IT-initiatives. As a consequence, the world over, there have been efforts to launch IT Initiatives in almost all the areas of human endeavour and sustenance. However, asymm...

The prevalence of categorical observations that are unique in a sample and also still unique in the population are usually taken as the measure of the overall risk of disclosure in the sample data. Samuels (1998) suggested adopting evolutionary processes and their associated urn models as a framework for estimating this prevalence. We re-examine his proposal and suggest several extensions that ...

ELECTRE TRI is a method designed to sort alternatives evaluated on several criteria into ordered categories. The original method uses limiting profiles. A recently introduced variant uses central profiles. We study the relations between these two variants. We do so by investigating if an ordered partition obtained with one variant can also be obtained by the other variant, after a suitable rede...

The actions of central banks have material effects on financial markets and can shape macroeconomic outcomes. Indeed, over recent decades it became widely accepted that monetary policy was the primary macroeconomic stabilisation tool and that monetary policy could effectively man...

Problemen uit de discrete wiskunde lijken op het eerste gezicht vaak erg simpel. Ze kunnen meestal gemakkelijk en zonder gebruik te maken van wiskundige begrippen worden geformuleerd. Toch komt het vaak voor dat zo’n ogenschijnlijk eenvoudig probleem nog open is of dat er, zoals bij het handelsreizigersprobleem, wel een oplossing gegeven kan worden, maar alleen een die onbruikbaar is omdat de r...

This paper gives a survey of the pioneer era in Norwegian scientific computing. Right after the Second World War research councils and research institutions were established and young scientists got scholarships to study abroad. Many caught interest in the new mathematical machines. In 1950, the Royal Norwegian Council for Scientific and Industrial Research decided to build a Norwegian computer...
