In this paper we look at some of the ingredients and processes involved in the understanding of mathematics. We analyze elements of mathematical knowledge, organize them in a coherent way and take note of certain classes of items that share…

Metrics used on development of expert systems is not a well investigated problem area. This article suggests some metrics to be used to measure the maturity of the conceptualization process and the complexity of the decision process in the problem…

Mountain papaya fruits (Vasconcella pubescens) were tested for firmness with a nondestructive acoustic method for 14 days after harvest. The response of each fruit was analyzed with the Fourier transform to obtain a firmness index (FI) based on the second…

In this paper, a method to combine visual and force information using the
information obtained from the movement flow-based visual servoing system is proposed. This
method allows not only to achieve a given desired position but also to specify the…

This paper demonstrates that it is possible to generate a reasonably accurate coordinate system on randomly distributed processors, using only local information and local communication. By coordinate systems we imply that each element assigns itself a logical coordinate that maps…

This paper describes an adaptive and autocalibrated method to track surfaces. To do so, a non time
dependent impedance control system is proposed. This method fuses visual and force information to track a
given trajectory maintaining the contact with the…

There is no enough evidence about the effects of the new information and communication technologies (ICT) in Spain and how these ICT cause differences between regions. So, the aim of this work is to analyze the regional disparities relative to…

Problematic aspects of intercultural communication are considered in the context of: an increasingly internationalized market for higher education; the globalization of knowledge; the compatibility of distinct national higher education cultures; and the capacity for successful cross-cultural cooperation. This is exemplified…

One of the habitats occupied by Mammillaria magnimamma is a 2000-year old lava-field, in Mexico City. The great ecological interest on this lava-field and the little knowledge there is regarding cacti population ecology have compelled us to analyse the demography…

This paper will undertake a critical review of a number of assumptions underpinning current thinking on understanding and supporting the internationalisation of the small and medium sized enterprise. The past twenty years has seen an explosion in academic research in…
