Recently, researchers have discovered that many of social, natural and biological networks are characterized by scale-free powerlaw connectivity distribution and a few densely populated nodes, known as hubs. We envision that wireless networks are directly deployed over such real-world networks to facilitate communication among participating entities. Here nodes move in such a way that they exhi...

This paper aims at studying the effect of the dynamic errors on surface measurements using three different types of touch trigger probes attached to a bridge-type-CMM. Unforeseeable dynamic root errors of a ductile touch trigger probing system have been characterized theoretically and experimentally as well. The results were employed in validating a developed analytical twodimensional-model (2D...

The paper presents a measurement framework for assessing the eGovernance maturity level of countries through the analysis of municipal websites. The paper also introduces the results of a survey carried out to apply and validate the framework. Applied to municipal websites of different countries, the framework considers websites content and design. For each country, the sample included three we...

We show how Statistical Shape Analysis, a set of techniques used to model the shapes of biological and other kind of objects in the natural sciences, can be used also to model the geometric shape of a manufactured part. We review Procrustes-based methods, and emphasize possible solutions to the basic problem of having corresponding, or matching, labels in the measured “landmarks”, the locations...

T purpose of the present study was to determine the relationship between adolescents' empathy and maturity of moral reasoning with their self-reported prosocial behaviour. Fourteenyear-oldadolescents (N=311) were administered scales measuring emotional empathy, fantasy and prosocial behaviour. Kohlberg's structured moral dilemmas were used to measure moral jUdgement maturity. Data were analysed...

CMMI contains a collection of Process Areas (PAs), and each PA contains many Specific Practices (SPs). However, the CMMI specification does not provide any explicit recommendation about which individual SPs can or should be implemented before other SPs. In this paper we identify dependencies between CMMI SPs in PAs in maturity level 2, and also between those PAs. We analyzed the text of the CMM...

A coordinate measuring machine (CMM) is a computer controlled device that uses a pro-grammable probe to obtain measurements on a part surface. Recently CMMs have become very popular for dimensional measurement in industry due to their exibility, accuracy, and ease of automation. Despite the advantages ooered by CMM's, problems have emerged with their use because tolerance standards require know...

The basis of the integration of activities related to the product life cycle is, mainly, the creation of a unique and coherent information model along all the stages in the cycle. Up to date, dimensional inspection activities have not been deeply analysed, possibly due to the fact that, their work influences are smaller than others, such us numerical analysis, materials or numerical control. Ho...
