Journal Guide

adsorption Science & Technology is a journal devoted to studies of adsorption and desorption phenomena, which publishes original research papers and critical review articles, with occasional special issues relating to particular topics and symposia. Recent issues have included studies of the pore structure and surface chemistry of active carbons, discussions of the application of the Dubinin-Radushkevich equation, the effect of cation-exchange on the sorption properties of zeolites, studies of the isosteric and differential heats of gas adsorption on microporous active carbons, and investigations of high-area manganese oxides by nitrogen adsorption.Ten issues a year are published. All papers and articles are subject to peer review before a decision is taken regarding their suitability and every effort is made to ensure their publication as quickly as possible.

© Nicolas Brodu. 2003 The astrolabe is an ancient astronomical computer for solving problemsrelating to time and the position of the sun and stars in the sky.Historians credit the invention of the astrolabe to classical Greece.Brass astrolabes were highly developed in the Islamic world of the 8thcentury and later. chiefly as an aid to navigation and as a way offinding the direction of Mecca. In the Middle Ages it found its wayback to Europe and became the chief navigational instrument until theinvention of the sextant in the 18th century.

Advanced computing methods and related technologies are changing the way engineers interact with the information infrastructure. Explicit knowledge representation formalisms and new reasoning techniques are no longer the sole territory of computer science. For knowledge-intensive tasks in engineering, a new philosophy and body of knowledge called Engineering Informatics is emerging.Advanced Engineering Informatics solicits research papers with particular emphases both on 'knowledge' and 'engineering applications'. As an international Journal, original papers typically:• Report progress in the engineering discipline of applying methods of engineering informatics.• Have engineering relevance and help provide the scientific base to make engineering decision-making more reliable, spontaneous and creative.• Contain novel research that demonstrates the science of supporting knowledge-intensive engineering tasks.• Validate the generality, power and scalability of new methods through vigorous evaluation, preferably both qualitatively and quantitatively.In addition, the Journal welcomes high quality review articles that summarise, compare, and evaluate methodologies and representations that are proposed for the field of engineering informatics. Similarly, summaries and comparisons of full-scale applications are welcomed, particularly those where scientific shortcomings have hindered success. Typically, such papers have expanded literature reviews and discussion of findings that reflect mastery of the current body of knowledge and propose novel additions to contemporary research.Papers missing explicit representation and use of knowledge, such as those describing soft computing techniques, mathematical optimization methods, pattern recognition techniques, and numerical computation methods, do not normally qualify for publication in the Journal. Papers must illustrate contributions using examples of automating and supporting knowledge intensive tasks in artifacts-centered engineering fields such as mechanical, manufacturing, architecture, civil, electrical, transportation, environmental, and chemical engineering. Papers that report application of an established method to a new engineering subdomain will qualify only if they convincingly demonstrate noteworthy new power, generality or scalability in comparison with previously reported validation results. Finally, papers that discuss software engineering issues only are not in the scope of this journal.
