This book collects papers fromworldexpertsinabroadvarietyofrelevantapplicationsofapproximation theory,includingpatternrecognitionandmachinelearning,multiscalemodel- ling of fluid flow, metrology, geometric modelling, the solution of differential equations, and signal and image processing, to mention a few. The 30 papers in this volume document new trends in approximation through recent theoretical developments, important computational aspects andmultidisciplinary applications,whichmakesitaperfecttextforgraduate studentsandresearchersfromscienceandengineeringwhowishtounderstand and develop numerical algorithms for solving their specific problems. An im- portant feature of the book is to bring together modern methods from statis- tics, mathematical modelling and numerical simulation for solving relevant problems with a wide range of inherent scales. Industrial mathematicians, in- cludingrepresentativesfromMicrosoftandSchlumbergermakecontributions, which fosters the transfer of the latest approximation methods to real-world applications. This book grew out of the fifth in the conference series on Algorithms for Approximation, which took place from 17th to 21st July 2005, in the beautiful city of Chester in England. The conference was supported by the NationalPhysicalLaboratoryandtheLondonMathematicalSociety,andhad around 90 delegates from over 20 different countries. The book has been arranged in six parts: Part I. Imaging and Data Mining; Part II. Numerical Simulation; Part III.Statistical Approximation Methods; Part IV. Data Fitting and Modelling; Part V. Differential and Integral Equations; Part VI. Special Functions and Approximation on Manifolds. VI Preface PartIgrewoutofaworkshopsponsoredbytheLondonMathematicalSo- ciety on Developments in Pattern Recognition and Data Mining and includes contributionsfromDonaldWunsch,thePresidentoftheInternationalNeural NetworksSocietyandChrisBurgesfromMicrosoft.Thenumericalsolutionof differential equations lies at the heart of practical application of approxima- tiontheory.Thenexttwopartscontaincontributionsinthisdirection.PartII demonstrates the growing trend in the transfer of approximation theory tools to the simulation of physical systems. In particular, radial basis functions are gaining a foothold in this regard. Part III has papers concerning the solution ofdifferentialequations,andespeciallydelaydifferentialequations.Thereali- sationthatstatisticalKrigingmethodsandradialbasisfunctioninterpolation are two sides of the same coin has led to an increase in interest in statisti- cal methods in the approximation community. Part IV reflects ongoing work in this direction. Part V contains recent developments in traditional areas of approximation theory, in the modelling of data using splines and radial basis functions. Part VI is concerned with special functions and approximation on manifolds such as spheres. Wearegratefultoalltheauthorswhohavesubmittedforthisvolume,es- pecially for their patience with the editors. The contributions to this volume haveallbeenrefereed,andthanksgoouttoalltherefereesfortheirtimelyand considered comments. Finally, we very much appreciate the cordial relation- ship we have had with Springer-Verlag, Heidelberg, through Martin Peters.
