| pierre gy: Sampling for Analytical Purposes Pierre Gy, 1998-06-29 Dr Gy, a pioneer in every sense of the word, has spent 50 years studying the best way to take a truly representative sample. His greatest achievement perhaps has been to introduce science into the black art of sampling. The now famous and widely used formula bearing his name means that sampling is no longer a lottery but an essential analytical tool. This very readable and practical book, written by Pierre Gy himself, is the first simple guide to Pierre Gy s method to be translated into English. Although Dr Gy s formula was originally developed for the sampling of solid material in mines, etc., the theoretical arguments are equally valid for the sampling of liquids and multi-phase media. This book is as interesting as a historical perspective as it is useful for the practising modern day analyst. |

| pierre gy: Yves Congar's Vision of the Church in a World of Unbelief Gabriel Flynn, 2017-03-02 Yves Congar (1904-1995) was one of the chief architects of a remarkable renewal in Roman Catholic ecclesiology in the twentieth century. His vision for ecclesial renewal led to a profound transformation of the Roman Catholic Church, its relationship with other churches and the world. This book considers the contribution made by Congar to that transformation. Situating Congar’s ecclesiology in the context of his whole theology, the book presents for the first time a comprehensive study of two related aspects of Congar's thought - unbelief and the notion of 'total ecclesiology'. Dr Flynn shows how unbelief provides the common inspiration for Congar's thought on the Church and constitutes the raison d’être for his entire programme of ecclesial reform at the Second Vatican Council. This study demonstrates how Congar's 'total ecclesiology' contributes to the restoration of unity and helps to redress unbelief. Congar's vision for the future and his programme for ecclesial renewal, centering on a church committed both to the preservation of its heritage and an openness to true reform, is shown to be still pertinent to the churches in the third millennium, a point accented by Pierre-Marie Gy, OP in his Preface to the work. |

| pierre gy: Developments in Numerical Ecology Pierre Legendre, Louis Legendre, 2013-06-29 From earlier ecological studies it has become apparent that simple univariate or bivariate statistics are often inappropriate, and that multivariate statistical analyses must be applied. Despite several difficulties arising from the application of multivariate methods, community ecology has acquired a mathematical framework, with three consequences: it can develop as an exact science; it can be applied operationally as a computer-assisted science to the solution of environmental problems; and it can exchange information with other disciplines using the language of mathematics. This book comprises the invited lectures, as well as working group reports, on the NATO workshop held in Roscoff (France) to improve the applicability of this new method numerical ecology to specific ecological problems. |

| pierre gy: Bayesian Nonparametrics via Neural Networks Herbert K. H. Lee, 2004-01-01 Bayesian Nonparametrics via Neural Networks is the first book to focus on neural networks in the context of nonparametric regression and classification, working within the Bayesian paradigm. Its goal is to demystify neural networks, putting them firmly in a statistical context rather than treating them as a black box. This approach is in contrast to existing books, which tend to treat neural networks as a machine learning algorithm instead of a statistical model. Once this underlying statistical model is recognized, other standard statistical techniques can be applied to improve the model. The Bayesian approach allows better accounting for uncertainty. This book covers uncertainty in model choice and methods to deal with this issue, exploring a number of ideas from statistics and machine learning. A detailed discussion on the choice of prior and new noninformative priors is included, along with a substantial literature review. Written for statisticians using statistical terminology, Bayesian Nonparametrics via Neural Networks will lead statisticians to an increased understanding of the neural network model and its applicability to real-world problems. |

Concerns cover estimation problems during a mine life, origin and credentials of geostatistics, precision of a sampling campaign and prediction of the effect of further sampling, exercises on grade-tonnage curves, theoretical models of distributions, and computational remarks on variances and covariances. The text then examines variogram and the practice of variogram modeling. Discussions focus on solving problems in one dimension, linear combinations and average values, theoretical models of isotropic variograms, the variogram as a geological features descriptor, and the variogram as the fundamental function in error computations. The manuscript ponders on statistical problems in sample preparation, orebody modeling, grade-tonnage curves, ore-waste selection, and planning problems, the practice of kriging, and the effective computation of block variances. The text is a valuable source of data for researchers interested in geostatistical ore reserve estimation. |
| pierre gy: Biochar Balwant Singh, Marta Camps-Arbestain, Johannes Lehmann, 2017-03 Interest in biochar among soil and environment researchers has increased dramatically over the past decade. Biochar initially attracted attention for its potential to improve soil fertility and to uncouple the carbon cycle, by storing carbon from the atmosphere in a form that can remain stable for hundreds to thousands of years. Later it was found that biochar had applications in environmental and water science, mining, microbial ecology and other fields. Beneficial effects of biochar and its environmental applications cannot be fully realised unless the chemical, physical, structural and surface properties of biochar are known. Currently many of the analytical procedures used for biochar analysis are not well defined, which makes it difficult to choose the right biochar for an intended use and to compare the existing data for biochars. Also, in some instances the use of inappropriate procedures has led to erroneous or inaccurate values for biochars in the scientific literature. Biochar: A Guide to Analytical Methods fills this gap and provides procedures and guidelines for routine and advanced characterisation of biochars. Written by experts, each chapter provides background to a technique or procedure, a stepwise guide to analyses, and includes data for biochars made from a range of feedstocks common to all presented methods. Discussion about the unique features, advantages and disadvantages of a particular technique is an explicit focus of this handbook for biochar analyses. Biochar is primarily intended for researchers, postgraduate students and practitioners who require knowledge of biochar properties. It will also serve as an important resource for researchers, industry and regulatory agencies dealing with biochar. |
