The objective of this paper is to get an insight into the chemical activation mechanism using KOH and NaOH as activated agents. Three
coals have been selected as carbon precursors. It was found that KOH and NaOH develop a similar…

CeO2 and Ce–Zr mixed oxides with different Ce:Zr ratios were prepared; characterised by Raman
spectroscopy, XRD, TEM, N2 adsorption at −196 ◦C, and H2-TPR; and tested for soot oxidation under
NOx/O2. Among the different mixed oxides, Ce0.76Zr0.24O2 provided the best…

There is considerable interest in real-world formation-maintenance tasks, where robots move together while maintaining a geometric shape. This interest is motivated by promise of robustly and efficiently moving multiple robots along a path, guided by a human operator. This paper…

A Discrete Event System (DES) is a discrete state space dynamic system that evolves in accordance with the instantaneous occurrence, at possibly unkown times, of physical events. Given a DES, its behavior (the sequence of displayed events) may not satisfy…

The ntcA gene from Synechococcus sp. strain PCC 7942 encodes a regulatory protein which is required for the expression of all of the genes known to be subject to repression by ammonium in that cyanobacterium. Homologs to ntcA have now…

In this paper we present our software framework for robotic applications, jde-neoc. This is the second implementation of our cognitive behavior-based architecture JDE, and it is aimed to overcome some of the limitations observed in three years using the first…

In this paper we present a novel approach to assigning roles to robots in a team of physical heterogeneous robots. Its members compete for these roles and get rewards for them. The rewards are used to determine each agent’s preferences…

Information Systems (IS) outsourcing is a growing phenomenon in present-day firms that has generally been characterised with an insufficient level of detail and analysis. This is mainly due to the fact that outsourcing has been studied as a set of…

In this communication, we report a new method to determine the wavefront
aberration function of personalized eyes. We obtain corneal surface data and
axial lengths for different eyes. With these data, we construct a diffractive model
of a human eye,…

PURPOSE: To compare the visual results of presbyLASIK patients to the best theoretical pseudoaccommodation that could be achieved using a multifocal refractive intraocular lens (IOL) model based on the optical
structure of a simulated AMO Array multifocal IOL.
METHODS: The…
