We are pleased to offer readers of International Journal of Computer Mathematics this Special Issue consisting of some of the most significant contributions presented at the 9th International Conference of Computational and Mathematical Methods in Science and Engineering, CMMSE – 2009, held at Gijon, Spain, 20 June and 1–3 July 2009. This special issue maintains the spirit of CMMSE special issues; see Citation19–24 for previous examples.
The nature of science is in sources of the motivation to understand the real world. The use of technology/engineering has been an undoubted benefit in the development of theories to guide the scientific exploration and, at the same time, major advances involving a substantial improving of the quality of life. CMMSE conferences constitute a forum for the discussion and presentation of new scientific theories, technological applications and new scientific problems that arise when trying to test scientific theories or go further in them when using the engineering support. As per the CMMSE conferences stated aims, this special issue aims to bring you important multidisciplinary contributions that combine both mathematical approaches and computational problems with direct applications in science and engineering. In this issue, we will find articles that could be classified from these different points of view when considering interactions between science and engineering.
Firstly, we have works where advances of mathematical and computational methods can apply to other sciences and from these, industrial, or technological advances could be derived: from categorical algebra to formal context analysis Citation11; from numerical methods Citation3 Citation16 to computer science Citation2 Citation15 Citation18; from lattices to relational theory Citation14.
Bioinformatics is an emerging discipline that is rapidly growing up with the benefit of computer science and mathematical methods. In this sense, we have selected an article that uses machine learning techniques to predict a determined health problem in humans Citation10, and a second one that makes use of pattern analysis to handle with of database of leukaemia patients Citation9.
Computational methods such as parallelization also contribute to the advancement of other disciplines. We can find three examples of this in the present issue, namely to coding theory Citation1, partial differential equations Citation16, and acoustic analysis Citation13.
Secondly, we have selected another group of works with a direct application in industry or technology as construction of a new geomechanical quality index Citation4, electricity production in hydroplants Citation5, improving harvest of vine leafs Citation17, or environmental models forecasting Citation8.
Finally, but not less importantly, we can get significant improvements in theoretical disciplines from a computational point of view. We have selected two important advances in classification of mathematical objects such as semifields Citation7 and Lie algebras Citation6 and the treatment of a problem on celestial bodies Citation12 by using powerful computational methods.
Considering all we do believe that this collection of articles can be useful and informative on the new perspectives and trends in interactions between science and engineering and hope that the reader can enjoy its reading, hoping that it can also serve as inspiration for new outcomes.
Finally, we want to thank all the authors and referees for their help in contributing excellently to this special volume.
