  • The fractal analysis is becoming a very useful tool to process obtained data from chaotic systems in geosciences. It can be used to resolve many ambiguities in this domain. This book contains eight chapters showing the recent applications of the fractal/mutifractal analysis in geosciences. Two chapters are devoted to applications of the fractal analysis in climatology, two of them to data of cosmic and solar geomagnetic data from observatories. Four chapters of the book contain some applications of the (multi-) fractal analysis in exploration geophysics.

  • A multitude of measurement units exist within astronomy, some of which are unique to the subject, causing discrepancies that are particularly apparent when astronomers collaborate with other disciplines in science and engineering. The International System of Units (SI) is based on a set of seven fundamental units from which other units may be derived. However, many astronomers are reluctant to drop their old and familiar systems. This handbook demonstrates the ease with which transformations from old units to SI units may be made.

  • The Observatory carries out front-line astronomical research in three key areas of astrophysics, namely: Solar-System Science, Solar Physics, and Stellar and Galactic Astrophysics. Solar-System research en- compasses the dynamical structure, evolution and origin of objects in the inner and outer solar system and comparative planetology and meteor physics.

  • The field of astronomy and astrophysics has advanced significantly with the advent of orbiting observatories. The ability to observe unobstructed by Earth’s atmosphere has opened new spectral windows and provided clearer, deeper views of the universe. Working with powerful new ground-based tools, astronomers and astrophysicists have revolutionized our understanding of the universe and the physical laws that govern its existence.

  • This book is dedicated to the memory of Gisèle Mersch whose life ended prematurely in June 2002. Back in the 1970s, when few people were using them, Gisèle introduced me to the arcane secrets of then advanced multivariate statistical methodologies. I was already involved in more classical statistical studies undertaken at Paris Observatory with Jean Jung: developing and applying maximumlikelihood algorithms to stellar photometric and kinematic data in order to derive absolute luminosities, distances and velocities in the solar neighborhood....

  • THE VIRTUAL OBSERVATORY Astronomers have always been early adopters of technology, and information technology has been no exception. There is a vast amount of astronomical data available on the Internet, ranging from spectacular processed images of planets to huge amounts of raw, processed and private data. Much of the data is well documented with citations, instrumental settings, and the type of processing that has been applied.

  • Computer facilities are used primarily for numerical analysis, computer modelling and data reduction; the computers and peripherals are largely funded by the DCAL, but occasionally by external research grants, for example those funded by the STFC, The Leverhulme Trust and various EU grants. Sta have access to a number of powerful iMac and Linux workstations, as well as the Stokes supercomputer at the Irish Centre for High-End Computing (ICHEC) and, through ICHEC, to occasional advanced computer training programmes.

  • The meteorological archive contains what is believed to be the longest continuous daily climate series from a single site in the UK and Ireland and one of the longest in the world. The climate station has been continuously maintained since 1795, with readings currently taken every day at 09:00 (GMT). Calibration of these data has enabled researchers and government agencies to use the Armagh series for reports and research into global warming. This is a subject of strategic importance for Northern Ireland as we move into an era of rapid climate change.
