Grob’s Basic Electronics provides thorough, comprehensive coverage of all of the important fundamentals of DC and AC circuit theory. It also covers the most common electronic devices and their applications. The book has an endless number of worked-out examples showing detailed step-by-step solutions. Also, a multiple-choice self-test as well as an abundance of homework problems appear at the end of every chapter in the book. New to the 13th edition is a chapter on “Three-Phase AC Power Systems”. Also, additional real-world applications have been added to this edition. The book is written for the beginning student who has no previous knowledge about electricity and electronics. A basic knowledge of algebra and trigonometry is beneficial for those students using this book.

The purpose of this book is to thoroughly prepare the reader for applied research in clustering. Cluster analysis comprises a class of statistical techniques for classifying multivariate data into groups or clusters based on their similar features. Clustering is nowadays widely used in several domains of research, such as social sciences, psychology, and marketing, highlighting its multidisciplinary nature. This book provides an accessible and comprehensive introduction to clustering and offers practical guidelines for applying clustering tools by carefully chosen real-life datasets and extensive data analyses. The procedures addressed in this book include traditional hard clustering methods and up-to-date developments in soft clustering. Attention is paid to practical examples and applications through the open source statistical software R. Commented R code and output for conducting, step by step, complete cluster analyses are available. The book is intended for researchers interested in applying clustering methods. Basic notions on theoretical issues and on R are provided so that professionals as well as novices with little or no background in the subject will benefit from the book.

This book has been developed as a forest inventory textbook for students and could also serve as a handbook for practical foresters. We have set out to keep the mathematics in the book at a fairly non-technical level, and therefore, although we deal with many issues that include highly sophisticated methodology, we try to present first and foremost the ideas behind them. For foresters who need more details, references are given to more advanced scientific papers and books in the fields of statistics and biometrics. Forest inventory books deal mostly with sampling and measurement issues, as found here in section I, but since forest inventories in many countries involve much more than this, we have also included material on forestry applications. Most applications nowadays involve remote sensing technology of some sort, so that section II deals mostly with the use of remote sensing material for this purpose. Section III deals with national inventories carried out in different parts of world, and section IV is an attempt to outline some future possibilities of forest inventory methodologies.

Jump start your journey with electronics! If you’ve thought about getting into electronics, but don’t know where to start, this book gives you the information you need. Starting with the basics of electricity and circuits, you'll be introduced to digital electronics and microcontrollers, capacitors and inductors, and amplification circuits – all while gaining the basic tools and information you need to start working with low-power electronics. Electronics for Beginners walks the fine line of focusing on projects-based learning, while still keeping electronics front and center. You'll learn the mathematics of circuits in an uncomplicated fashion and see how schematics map on to actual breadboards. Written for the absolute beginner, this book steers clear of being too math heavy, giving readers the key information they need to get started on their electronics journey. What You’ll Learn Review the basic “patterns” of resistor usage—pull up, pull down, voltage divider, and current limiter Understand the requirements for circuits and how they are put together Read and differentiate what various parts of the schematics do Decide what considerations to take when choosing components Use all battery-powered circuits, so projects are safe Who This Book Is For Makers, students, and beginners of any age interested in getting started with electronics.
