The Horizon Dat

This book describes and provides many detailed examples of implementing Digital Soil Mapping (DSM) using R. The work adheres to Digital Soil Mapping theory, and presents a strong focus on how to apply it. DSM exercises are also included and cover procedures for handling and manipulating soil and spatial data in R. The book also introduces the basic concepts and practices for building spatial soil prediction functions, and then ultimately producing digital soil maps.

Barrows, as burial markers, are ubiquitous throughout North-Western Europe. In some regions dense concentrations of monuments form peculiar configurations such as long alignments while in others they are spread out extensively, dotting vast areas with hundreds of mounds. These vast barrow landscapes came about through thousands of years of additions by several successive prehistoric and historic communities. Yet little is known about how these landscapes developed and came about. That is what this research set out to do. By unravelling the histories of specific barrow landscapes in the Low Countries, several distinct activity phases of intense barrow construction could be recognised. Each of these phases contributed in a particular fashion to how the barrow landscape developed and reveals shifting attitudes to these landscape monuments. By creating new monuments in a specific place and in a particular fashion, prehistoric communities purposefully transformed the form and shape of the barrow landscape. Using several GIS-techniques such as a skyline-analysis, this research was able to demonstrate how each barrow then took up a specific (and different) position within such a social landscape. While the majority of the barrows were only visible from relatively close by, specific monuments took up a dominating position, cresting the horizon, and they were visible from much further away. It was argued that these burial mounds remained important landscape monuments on the purple heathlands. They continued to attract attention, and by their visibility ensured to endure in the collective memory of the communities shaping themselves around these monuments. This publication is part of the Ancestral Mounds Research Project of the University of Leiden.

High Performance Computing: Modern Systems and Practices is a fully comprehensive and easily accessible treatment of high performance computing, covering fundamental concepts and essential knowledge while also providing key skills training. With this book, domain scientists will learn how to use supercomputers as a key tool in their quest for new knowledge. In addition, practicing engineers will discover how supercomputers can employ HPC systems and methods to the design and simulation of innovative products, and students will begin their careers with an understanding of possible directions for future research and development in HPC. Those who maintain and administer commodity clusters will find this textbook provides essential coverage of not only what HPC systems do, but how they are used. Covers enabling technologies, system architectures and operating systems, parallel programming languages and algorithms, scientific visualization, correctness and performance debugging tools and methods, GPU accelerators and big data problems Provides numerous examples that explore the basics of supercomputing, while also providing practical training in the real use of high-end computers Helps users with informative and practical examples that build knowledge and skills through incremental steps Features sidebars of background and context to present a live history and culture of this unique field Includes online resources, such as recorded lectures from the authors’ HPC courses

Guide to Observing Deep-Sky Objects is an invaluable reference for all amateur astronomers. The book contains, for each constellation, (1) a star chart showing the Bayer labels, (2) a table for many of the stars in the constellation, along with their positions and magnitudes, and (3) a table of the major deep-sky objects in the constellation, with relevant observational data. Facing pages provide unique year-long graphs that show when the constellation is visible in the sky, which allows the user to quickly determine whether a given constellation can be seen, and when the best time to see it will be.

This book offers a survey of current work in Nordic and General Linguistics, with a special focus on language contact. The papers in this book were presented at the 11th International Conference of Nordic and General Linguistics (ICNGL) in Freiburg. The ICNGL conference series aims to facilitate the exchange of ideas on Scandinavian and other languages, between researchers from the Nordic countries and elsewhere. The present volume focuses on language contact, which has always been a topic of great interest in Nordic Linguistics. Additionally, the contributions in this book address issues of phonology, morpho-syntax, syntax, and grammaticalization. The book is meant to be a snapshot of Nordic Linguistics as it is practiced today, reflecting at the same time its established research traditions as well as its forages into new methodologies and theories.
