Handbook of Quantitative Forest Genetics (Forestry Sciences #39)

by Lauren Fins

This handbook was designed as a reference tool for forest geneticists, tree breeders and other tree improvement personnel, as well as a textbook for university courses and short-courses at the graduate level in quantitative genetics. The chapters focus on the decision points faced by quantitative geneticists and breeders in designing programs and analyzing data. Beginning with a justification for the use of quantitative genetics in decision making in tree improvement programs, the book continues with a brief presentation of fundamental principles, followed by discussions and evaluations of mating designs and field test designs, the use of best linear predictors to estimate breeding values, the use of computer programs in the analysis of variance for genetic information, the deployment of genetically improved stock for capturing gains, the use of economic models for program justification, and the development of seed transfer guidelines.

Harmonic Analysis and Discrete Potential Theory

by M. A. Picardello

Harmonic Function Theory (Graduate Texts in Mathematics #137)

by Sheldon Axler Paul Bourdon Wade Ramey

Harmonic functions - the solutions of Laplace's equation - play a crucial role in many areas of mathematics, physics, and engineering. Avoiding the disorganization and inconsistent notation of other expositions, the authors approach the field from a more function-theoretic perspective, emphasizing techniques and results that will seem natural to mathematicians comfortable with complex function theory and harmonic analysis; prerequisites for the book are a solid foundation in real and complex analysis together with some basic results from functional analysis. Topics covered include: basic properties of harmonic functions defined on subsets of Rn, including Poisson integrals; properties bounded functions and positive functions, including Liouville's and Cauchy's theorems; the Kelvin transform; Spherical harmonics; hp theory on the unit ball and on half-spaces; harmonic Bergman spaces; the decomposition theorem; Laurent expansions and classification of isolated singularities; and boundary behavior. An appendix describes routines for use with MATHEMATICA to manipulate some of the expressions that arise in the study of harmonic functions.

Higher Algebraic K-Theory: An Overview (Lecture Notes in Mathematics #1491)

by Emilio Lluis-Puebla Jean-Louis Loday Henri Gillet Christophe Soule Victor Snaith

This book is a general introduction to Higher Algebraic K-groups of rings and algebraic varieties, which were first defined by Quillen at the beginning of the 70's. These K-groups happen to be useful in many different fields, including topology, algebraic geometry, algebra and number theory. The goal of this volume is to provide graduate students, teachers and researchers with basic definitions, concepts and results, and to give a sampling of current directions of research. Written by five specialists of different parts of the subject, each set of lectures reflects the particular perspective ofits author. As such, this volume can serve as a primer (if not as a technical basic textbook) for mathematicians from many different fields of interest.

Höhere Mathematik für Ingenieure: Bd. 2: Lineare Algebra (Teubner-Ingenieurmathematik)

by Klemens Burg Herbert Haf Friedrich Wille

Der vorliegende Band 11 der Höheren Mathematik für Ingenieure enthält eine in sich geschlossene Darstellung der "Linearen Algebra" mit vielfältigen Bezügen zur Technik und Naturwissenschaft. Adressaten sind in erster Linie Ingenieurstudenten, aber auch Studenten der Angewand­ ten Mathematik und Physik, etwa der Richtungen Technomathematik, mathematische Informatik, theoretische Physik. Sicherlich wird auch der "reine" Mathematiker für ihn Interessantes in dem Buch finden. Der Band ist - bis auf wenige Querverbindungen - unabhängig vom Band I "Analysis" gestaltet, so daß man einen Kursus über Ingenieurmathematik auch mit dem vorliegen­ den Buch beginnen kann. (Beim Studium der Elektrotechnik wird z. B. gerne mit Linea­ rer Algebra begonnen.) Vorausgesetzt werden lediglich Kenntnisse aus der Schulmathe­ matik. Auch die einzelnen Abschnitte des Buches sind mit einer gewissen Unabhängigkeit von­ einander konzipiert, so daß Quereinstiege möglich sind. Dem Leser, der schon einen ersten Kursus über Lineare Algebra absolviert hat, steht in diesem Bande ein Nach­ schlagewerk zur Verfügung, welches ihm in der Praxis oder beim Examen eine Hilfe ist. Die Bedeutung der Linearen Algebra für Technik und Naturwissenschaft ist in diesem Jahrhundert stark gestiegen. Insbesondere ist die Matrizen-Rechnung, die sich erst in den dreißiger Jahren in Physik und Technik durchzusetzen begann, heute ein starkes Hilfsmittel in der Hand des Ingenieurs. Darüber hinaus führt die Synthese von Linearer Algebra und Analysis zur Funktionalanalysis, die gerade in den letzten Jahrzehnten zu einem leistungsfähigen theoretischen Instrumentarium für Naturwissenschaft und Tech­ nik geworden ist.

Industrial Applications of Neural Networks: Project ANNIE Handbook (Research Reports Esprit #1)

by Ian F. Croall John P. Mason

Neural network technology encompasses a class of methods which attempt to mimic the basic structures used in the brain for information processing. Thetechnology is aimed at problems such as pattern recognition which are difficult for traditional computational methods. Neural networks have potential applications in many industrial areas such as advanced robotics, operations research, and process engineering. This book is concerned with the application of neural network technology to real industrial problems. It summarizes a three-year collaborative international project called ANNIE (Applications of Neural Networks for Industry in Europe) which was jointly funded by industry and the European Commission within the ESPRIT programme. As a record of a working project, the book gives an insight into the real problems faced in taking a new technology from the workbench into a live industrial application, and shows just how it can be achieved. It stresses the comparison between neural networks and conventional approaches. Even the non-specialist reader will benefit from understanding the limitations as well as the advantages of the new technology.

Information Bounds and Nonparametric Maximum Likelihood Estimation (Oberwolfach Seminars #19)

by P. Groeneboom J.A. Wellner

This book contains the lecture notes for a DMV course presented by the authors at Gunzburg, Germany, in September, 1990. In the course we sketched the theory of information bounds for non parametric and semiparametric models, and developed the theory of non parametric maximum likelihood estimation in several particular inverse problems: interval censoring and deconvolution models. Part I, based on Jon Wellner's lectures, gives a brief sketch of information lower bound theory: Hajek's convolution theorem and extensions, useful minimax bounds for parametric problems due to Ibragimov and Has'minskii, and a recent result characterizing differentiable functionals due to van der Vaart (1991). The differentiability theorem is illustrated with the examples of interval censoring and deconvolution (which are pursued from the estimation perspective in part II). The differentiability theorem gives a way of clearly distinguishing situations in which 1 2 the parameter of interest can be estimated at rate n / and situations in which this is not the case. However it says nothing about which rates to expect when the functional is not differentiable. Even the casual reader will notice that several models are introduced, but not pursued in any detail; many problems remain. Part II, based on Piet Groeneboom's lectures, focuses on non parametric maximum likelihood estimates (NPMLE's) for certain inverse problems. The first chapter deals with the interval censoring problem.

Information Processing in the Cortex: Experiments and Theory

by Ad Aertsen Valentino Braitenberg

There is a tradition of theoretical brain science which started in the forties (Wiener, McCulloch, Turing, Craik, Hebb). This was continued by a small number of people without interruption up to the present. It has definitely provided main guiding lines for brain science, the devel­ opment of which has been spectacular in the last decades. However, within the bulk of experimental neuroscience, the theoreticians some­ times had a difficult stand, since it was felt that the times were not ripe yet and the methods not yet available for a development of a true theoretical speciality in this field. Thus theory remained in the hands of a fairly small club which recruited its members from theoretical physicists, mathematicians and some experimentalists with amateurish theoretical leanings. The boom of approaches which go by the name of 'computational neuroscience', 'neuronal networks', 'associative mem­ ory', 'spinglass theory', 'parallel processing' etc. should not blind one for the fact that the group of people professionally interested in real­ istic models of brain function up to the present date remains rather small and suffers from a lack of professional organization. It was against this background that we decided to organize a meet­ ing on Theoretical Brain Science. The meeting was held April 18 - 20, 1990 and took place at Schloss Ringberg, West-Germany, a facility sponsored by the Max-Planck-Society.
