This article describes the process whereby digitization of a journal is used to preserve and provide access to the contents on the World Wide Web. The journal chosen, The Canadian Architect and Builder, was the only professional architectural journal published…

El libro está orientado a las ténicas de diseño para mejorar la performance de sistemas de computación y especialmente hacia aquellas técnicas que involucren paralelismo.

El Profesor Michalewicz ofrece, en su libro, una motivante introducción al tema abarcando cada uno de los enfoques evolutivos aunque con preferencia hacia los algoritmos genéticos y sus extensiones: los programas evolutivos

This book presents the fundamentals of discrete-time signals, systems, algorithms and applications for students in electrical engineering or computer science. It covers both time-domain and frequency- domain methods for the analysis of linear, discrete-time systems.

Silver halide sensitized gelatin (SHSG) is an interesting technique for the production of holographic optical elements. It combines the high sensitivity of photographic emulsions with the well-known low scattering and high diffraction efficiency corresponding to dichromated gelatin. In this paper…

The electrochemical oxidation of serine and alanine was performed at Pt(100) and Pt(110) electrodes and analysed by means of FTIR spectroscopy and cyclic voltammetry. The open circuit adsorption of both amino acids was also investigated. The oxidation of serine gives…

Cyclic voltammetry (CV) and Fourier transform infrared reflection-absorption spectroscopy (FT-IRRAS) have been combined to analyse the oxidation of methylamine and ethylamine on platinum single crystal electrodes in an acidic medium. The oxidation of both amines on Pt(hkl) electrodes gives rise…

The irreversible adsorption of methylamine at platinum single-crystal electrodes has been studied by a combination of electrochemical and in situ spectroscopic techniques. From purely electrochemical data, it has been stated that the adsorption of CH3NH2 molecules results in significant alteration…

The electroreflectance (ER) technique has been applied to the study of a Pt(111) electrode in different acidic and alkaline electrolytes. The variation in the normalised potential derivative of the reflectance signal, 1/R(dR/dE) is observed in sulphuric and perchloric acid media…
