Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

International custom "as evidence of a general practice accepted as law", is considered one of the two main sources of international law as it primarily derives from the conduct of sovereign States, but is also closely connected with the role of the international judge when identifying the applicable customary rule, a function it shares with the bodies in charge of its codification (and progressive development), starting with the International Law Commission. Though mainly considered to be general international law, international custom has a complex relationship with many specific fields of law and specific regions of the world. The editor provides comprehensive research published in the last seven decades, invaluable to everyone interested in the field of customary international law.

This collection of essays gathers contributions from leading international lawyers from different countries, generations and angles with the aim of highlighting the multifaceted history of international law. This volume questions and analyses the origins and foundations of the international legal system. A particular attention is devoted to Hugo Grotius as one of the founding fathers of the law of nations. Several contributions further question the positivist tradition initiated by Vattel and endorsed by scholars of the 19th Century. This immersion in the intellectual origins of international law is enriched by an inquiry into the practice of the law of nations, including its main patterns and changing evolution as well as the role of non-western traditions and the impact of colonization. Le present ouvrage reunit les contributions de juristes internationaux reconnus en vue d'eclairer les multiples facettes de l'histoire du droit international public. L'ouvrage analyse et questionne les origines et les fondements de l'ordre juridique international. Une attention toute particuliere est dediee a Hugo Grotius l'un des peres fondateurs du droit international. D'autres contributions questionnent egalement la tradition positiviste initiee par Vattel et confortee par la doctrine du 19eme siecle. Cette immersion dans les origines doctrinales du systeme juridique international est enrichie par l'etude de la pratique du droit international public, son evolution ainsi que le role des traditions non-occidentales et l'impact de la colonisation.

Water is flowing all around us; in nature, in the home, and even inside our bodies. In this descriptive storybook, young readers will dive into simple explanations of the different states of water, how weather cycles work, how water reaches our homes, and how crucial it is for daily life. They'll soak up some startling statistics, too - did you know, three quarters of the Earth's surface is covered in water? This title is part of the My First Discovery paperback series - a unique collection of beautifully illustrated information books for children aged 4 to 7, with simple language to aid learning and realistic artwork to inspire young minds. There are 8 transparent overlay pages, which reveal hidden surprises and make the pages come alive. With free access to a brand new audio app, children can listen and read along at their own pace, page by page.

Parametric cost estimating, when properly used, is a very powerful and cost effective technique. Unfortunately, this technique is often misunderstood and rejected by many potential users for whom it could be a beneficial tool. The development of an agreement on how to use it and how to recognise its limitations is a major benefit to the cost estimating community.

From Product Description to Cost: A Practical Approach:

a [ presents different ways of parametrically forecasting costs, and the advantages and disadvantages of these methods by using real examples from the mechanical, software and building industries;

a [ discusses most of the mathematical procedures which are useful for parametrically forecasting costs;

a [ introduces the judgement needed to audit the ways in which these forecasting techniques are used, firstly as a process, and secondly as a tool to generate estimates.

Volume 1: The Parametric Approach contains four parts. Over the course of this volume, cost estimating is introduced; the preparation of data before utilization is discussed; the basic concepts of a ~generala (TM) cost estimating models are examined; the use of cost models is considered and finally, risk analysis (as it can be used during parametric cost estimating) is introduced.

This textbook presents in a unified manner the fundamentals of both continuous and discrete versions of the Fourier and Laplace transforms. These transforms play an important role in the analysis of all kinds of physical phenomena. As a link between the various applications of these transforms the authors use the theory of signals and systems, as well as the theory of ordinary and partial differential equations. The book is divided into four major parts: periodic functions and Fourier series, non-periodic functions and the Fourier integral, switched-on signals and the Laplace transform, and finally the discrete versions of these transforms, in particular the Discrete Fourier Transform together with its fast implementation, and the z-transform. This textbook is designed for self-study. It includes many worked examples, together with more than 120 exercises, and will be of great value to undergraduates and graduate students in applied mathematics, electrical engineering, physics and computer science.
