In this paper, we consider the finitely presented groups $G_{m}$ and $K(s,l)$ as follows;$$G_{m}=langle a,b| a^m=b^m=1,~[a,b]^a=[a,b],~[a,b]^b=[a,b]rangle $$$$K(s,l)=langle a,b|ab^s=b^la,~ba^s=a^lbrangle;$$and find the $n^{th}$-commutativity degree for each of them. Also we study the concept of $n$-abelianity on these groups, where $m,n,s$ and $l$ are positive integers, $m,ngeq 2$ and $g.c.d(s,...

Much evidence has been collected to date which shows that repulsive electron-electron interaction can lead to the formation of particle pairs in a one-dimensional random energy landscape. The localization length 2 of these pair states is nite, but larger than the localization length 1 of the individual particles. After a short review of previous work, we present numerical evidence for this eeec...

The aim of this paper is to explore the relationship between wages, human capital and investment in financial assets with risky returns at the individual level. To explore this relationship from an international perspective, we analyse individual level data from the British Household Panel Survey, the German Socio-Economic Panel and the U.S. Panel Study of Income Dynamics. Our findings suggest ...

This paper reports a set of experiments motivated by the observation that the design of group decision processes is crucial to the success of electronic meeting room usage. Decision processes can be designed with more emphasis either on exchanging meanings (discussing issues) or exchanging artefacts (generating and structuring topics). Our problem is that, given a particular case to be discusse...

In this paper we present some new versions of Brooks-Jewett and Dieudonné-type theorems for (l)-group-valued measures.

While most knowledge engineers believe that the quality of results obtained from Bayesian networks is not too sensitive to imprecision in probabilities, this remains a conjecture with only modest empirical support. Our work on a Bayesian network model for diagnosis of liver disorders, Hepar II, presented us with an opportunity to test this conjecture in a practical setting. We present the resul...
