Model-Based EIS Performability Analysis

In this paper we propose a methodology for the modelling, verification and performance evaluation of communication components of software for enterprise information systems. The methodology is centered upon model-driven development using a subset of UML 2.0 diagrams. It is supported by the proSPEX model processing tool which offers a simulation-based executable verification environment. The mod...

EROs in the EIS fields

The publicly available EIS-DEEP optical-NIR data for the AXAF (Chandra) Deep Field have been used to construct samples of Extremely Red Objects (EROs) using various single-band and multi-band color criteria. In this work we define as EROs objects with colors consistent with passively evolving elliptical galaxies at z ≥ 1. The EROs surface densities we derive are intermediate between previous pu...

Confirming EIS Clusters . Multi - object Spectroscopy

Clusters of galaxies arise from exceptionally high peaks of the primordial fluctuation density field. Their properties as a function of redshift, z, are therefore highly sensitive to the nature of such cosmic fluctuations. It is therefore very important to have a sample of galaxy clusters covering as wide a redshift range as possible. Recently, Olsen et al. (1999) and Scodeggio et al. (1999) ha...

Oxygen Reduction on Platinum: An EIS Study

The oxygen reduction reaction (ORR) on platinum over yttria-stabilized zirconia (YSZ) is examined via electrochemical impedance spectroscopy (EIS) for oxygen partial pressures between 10−4 and 1 atm and at temperatures between 475 and 700‰. Use of photolithographic techniques in electrode fabrication renders a precise geometry of the Pt electrodes. Circular electrode design leads to cylindrical...
