The asymptotic behaviours for small and large amplitudes, A, of the period for a nonlinear oscillator, where the square of the angular frequency depends quadratically on the velocity, are obtained. These asymptotic expressions are compared with the exact period, T(A),…

This paper deals with the problem of planning the Center of Mass (CoM) trajectory of a humanoid robot while its feet follow an omnidirectional walking pattern. This trajectory should satisfy the dynamic stability criterion to ensure analytically that the Zero…

The electrocatalytic oxidation of ferrocene (Fc) at neutral pH in aqueous solution has been studied over thin films of electroactive sulfonated polyaniline (SPAN) by cyclic voltammetry. Strong adsorption of the oxidised species (ferrocenium ion) on the polymer arises as the…

There are few practical tools for how we can develop the trust needed to be able to work with ourselves and our colleagues, nor on how
we can develop the organisational conditions that enable us to trust ourselves and others,…

Purpose: A number of studies and writings have presented ideas about new working practices that might be embraced in the twenty-first century. Moreover, that, employers would seek to gain their commitment by adopting the high working practices of high performance…

In this interview, Adrian Lee talks candidly about the current challenges facing police and public sector leadership. The Chief Constable's studies of theology, philosophy and law prior to him joining the police service have shaped and formed his sense of…

This paper summarizes the research study carried out in 1979 as part of an MSc. The study has two purposes: to analyse, in sociological terms, the nursing process development and to understand whether it can make a practical contribution to…

This is the pre-peer reviewed version of the following article: The potential of parasitoid Hymenoptera as bioindicators of arthropod diversity in agricultural grasslands 2011, 48 (2):382 Journal of Applied Ecology, which has been published in final form at: http://doi.wiley.com/10.1111/j.1365-2664.2010.01937.x, 1. As…

This paper mainly concerns the study of a large class of variational systems governed by parametric generalized equations, which encompass variational and hemivariational inequalities, complementarity problems, first-order optimality conditions, and other optimization-related models important for optimization theory and applications. An…

The goal of this work was centered in the graph visualization. The hope is that the extra dimension would give, literally, more space, and that this would ease the problem of displaying large structures. In spite of their apparent simplicity,…
