A process model is very often used for system analysis, design and management in various application areas. Using a process model has the advantage that it has only to be as precise as necessary within the parameters of the individual field of application, whereas the precision externally is less important. This makes process modeling easier and open for structuring. The contributions deal with different approaches to process modelling, especially in the areas of business process modelling, logistics and production processes and water systems.

Use R to turn data into insight, knowledge, and understanding. With this practical book, aspiring data scientists will learn how to do data science with R and RStudio, along with the tidyverse—a collection of R packages designed to work together to make data science fast, fluent, and fun. Even if you have no programming experience, this updated edition will have you doing data science quickly. You'll learn how to import, transform, and visualize your data and communicate the results. And you'll get a complete, big-picture understanding of the data science cycle and the basic tools you need to manage the details. Updated for the latest tidyverse features and best practices, new chapters show you how to get data from spreadsheets, databases, and websites. Exercises help you practice what you've learned along the way. You'll understand how to: Visualize: Create plots for data exploration and communication of results Transform: Discover variable types and the tools to work with them Import: Get data into R and in a form convenient for analysis Program: Learn R tools for solving data problems with greater clarity and ease Communicate: Integrate prose, code, and results with Quarto

Making systems easier to use implies increasingly complex management of communication between users and applications. An increasing part of the application program is devoted to the user interface. In order to manage this complexity, it is very important to have tools, notations, and methodologies that support the designer's work during the refinement process from specification to implementation. The purpose of this proceedings of the first (1994) Eurographics workshop on this area is to review the state of the art. It compares the different existing approaches in order to identify the principal requirements and the most suitable notations and methods, and indicates the relevant results.

This volume offers presentations at the most recent events of the IFLA Newspapers Section (Santiago de Chile, May 2007 & Durban, August 2007). The Santiago International Newspaper Conference as the first of its kind, aimed at taking stock of the Latin American newspaper collection and analyzing current activities from the basics to sophisticated digitization and software technologies. Most presentations are offered in Spanish and English. This publication focuses on the key issues in newspaper librarianship - preservation and access - in which digitization is a very important tool. Este volumen ofrece las presentaciones aportadas a las sesiones más recientes de la Sección de Periódicos de la IFLA (en Santiago de Chile, Mayo de 2007, y en Durban, Agosto de 2007). La Conferencia Internacional sobre Periódicos celebrada en Santiago de Chile, en tanto que la primera de su especialidad, estuvo dedicada a revisar la situación de las colecciones de periódicos en Latinoamérica y analizar las necesidades y actividades actuales en este campo, que van desde los aspectos más básicos hasta la mayor sofisticación en digitalización y en el empleo de todo tipo de software. Para lograr que los resultados de este acontecimiento estén disponibles para la comunidad bibliotecaria en general, la mayor parte de las presentaciones incluidas están en español y en inglés. Esta publicación se centra en las cuestiones clave de la biblioteconomía en relación con los periódicos - conservación y acceso - para las que la digitalización constituye un instrumento muy importante. El volumen recoge tanto los desarrollos más recientes como los muchos retos que quedan por afrontar.

"I enjoyed reading this book immensely. The author was uncommonly careful in his explanations. I'd recommend this book to anyone writing scientific application codes." -Peter S. Pacheco, University of San Francisco "This text provides a useful overview of an area that is currently not addressed in any book. The presentation of parallel I/O issues across all levels of abstraction is this book's greatest strength." -Alan Sussman, University of Maryland Scientific and technical programmers can no longer afford to treat I/O as an afterthought. The speed, memory size, and disk capacity of parallel computers continue to grow rapidly, but the rate at which disk drives can read and write data is improving far less quickly. As a result, the performance of carefully tuned parallel programs can slow dramatically when they read or write files-and the problem is likely to get far worse. Parallel input and output techniques can help solve this problem by creating multiple data paths between memory and disks. However, simply adding disk drives to an I/O system without considering the overall software design will not significantly improve performance. To reap the full benefits of a parallel I/O system, application programmers must understand how parallel I/O systems work and where the performance pitfalls lie. Parallel I/O for High Performance Computing directly addresses this critical need by examining parallel I/O from the bottom up. This important new book is recommended to anyone writing scientific application codes as the best single source on I/O techniques and to computer scientists as a solid up-to-date introduction to parallel I/O research. Features: An overview of key I/O issues at all levels of abstraction-including hardware, through the OS and file systems, up to very high-level scientific libraries. Describes the important features of MPI-IO, netCDF, and HDF-5 and presents numerous examples illustrating how to use each of these I/O interfaces. Addresses the basic question of how to read and write data efficiently in HPC applications. An explanation of various layers of storage - and techniques for using disks (and sometimes tapes) effectively in HPC applications.

Proceedings of the Third International Conference on Data and Knowledge Bases: Improving Usability and Responsiveness compiles papers presented at the Third International Conference on Data and Knowledge Bases held in Jerusalem, Israel on June 28-30, 1988. This book discusses the management system for graph-like documents, selection of processing strategies for different recursive queries, and supporting concurrent access to facts in logic programs. The design considerations for a Prolog database engine, experience with the domain algebra, and two level transaction management in a multiprocessor database machine are also described. This publication likewise covers the non-deterministic choice in Datalog and locally balanced compact Trie Hashing. This compilation is a good source for researchers and specialists of disciplines related to computer science.

This Festschrift is published in honor of Edward A. Lee, Robert S. Pepper Distinguished Professor Emeritus and Professor in the Graduate School in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley, USA, on the occasion of his 60th birthday. The title of this Festschrift is “Principles of Modeling" because Edward A. Lee has long been devoted to research that centers on the role of models in science and engineering. He has been examining the use and limitations of models, their formal properties, their role in cognition and interplay with creativity, and their ability to represent reality and physics. The Festschrift contains 29 papers that feature the broad range of Edward A. Lee’s research topics; such as embedded systems; real-time computing; computer architecture; modeling and simulation, and systems design.
