Find out everything you need to know to build powerful robots with the most up-to-date ROS About This Book This comprehensive, yet easy-to-follow guide will help you find your way through the ROS framework Successfully design and simulate your 3D robot model and use powerful robotics algorithms and tools to program and set up your robots with an unparalleled experience by using the exciting new features from Robot Kinetic Use the latest version of gazebo simulator, OpenCV 3.0, and C++11 standard for your own algorithms Who This Book Is For This book is suitable for an ROS beginner as well as an experienced ROS roboticist or ROS user or developer who is curious to learn ROS Kinetic and its features to make an autonomous Robot. The book is also suitable for those who want to integrate sensors and embedded systems with other software and tools using ROS as a framework. What You Will Learn Understand the concepts of ROS, the command-line tools, visualization GUIs, and how to debug ROS Connect robot sensors and actuators to ROS Obtain and analyze data from cameras and 3D sensors Use Gazebo for robot/sensor and environment simulation Design a robot and see how to make it map the environment, navigate autonomously, and manipulate objects in the environment using MoveIt! Add vision capabilities to the robot using OpenCV 3.0 Add 3D perception capabilities to the robot using the latest version of PCL In Detail Building and programming a robot can be cumbersome and time-consuming, but not when you have the right collection of tools, libraries, and more importantly expert collaboration. ROS enables collaborative software development and offers an unmatched simulated environment that simplifies the entire robot building process. This book is packed with hands-on examples that will help you program your robot and give you complete solutions using open source ROS libraries and tools. It also shows you how to use virtual machines and Docker containers to simplify the installation of Ubuntu and the ROS framework, so you can start working in an isolated and control environment without changing your regular computer setup. It starts with the installation and basic concepts, then continues with more complex modules available in ROS such as sensors and actuators integration (drivers), navigation and mapping (so you can create an autonomous mobile robot), manipulation, Computer Vision, perception in 3D with PCL, and more. By the end of the book, you’ll be able to leverage all the ROS Kinetic features to build a fully fledged robot for all your needs. Style and approach This book is packed with hands-on examples that will help you program your robot and give you complete solutions using ROS open source libraries and tools. All the robotics concepts and modules are explained and multiple examples are provided so that you can understand them easily.

Master text-taming techniques and build effective text-processing applications with R About This Book Develop all the relevant skills for building text-mining apps with R with this easy-to-follow guide Gain in-depth understanding of the text mining process with lucid implementation in the R language Example-rich guide that lets you gain high-quality information from text data Who This Book Is For If you are an R programmer, analyst, or data scientist who wants to gain experience in performing text data mining and analytics with R, then this book is for you. Exposure to working with statistical methods and language processing would be helpful. What You Will Learn Get acquainted with some of the highly efficient R packages such as OpenNLP and RWeka to perform various steps in the text mining process Access and manipulate data from different sources such as JSON and HTTP Process text using regular expressions Get to know the different approaches of tagging texts, such as POS tagging, to get started with text analysis Explore different dimensionality reduction techniques, such as Principal Component Analysis (PCA), and understand its implementation in R Discover the underlying themes or topics that are present in an unstructured collection of documents, using common topic models such as Latent Dirichlet Allocation (LDA) Build a baseline sentence completing application Perform entity extraction and named entity recognition using R In Detail Text Mining (or text data mining or text analytics) is the process of extracting useful and high-quality information from text by devising patterns and trends. R provides an extensive ecosystem to mine text through its many frameworks and packages. Starting with basic information about the statistics concepts used in text mining, this book will teach you how to access, cleanse, and process text using the R language and will equip you with the tools and the associated knowledge about different tagging, chunking, and entailment approaches and their usage in natural language processing. Moving on, this book will teach you different dimensionality reduction techniques and their implementation in R. Next, we will cover pattern recognition in text data utilizing classification mechanisms, perform entity recognition, and develop an ontology learning framework. By the end of the book, you will develop a practical application from the concepts learned, and will understand how text mining can be leveraged to analyze the massively available data on social media. Style and approach This book takes a hands-on, example-driven approach to the text mining process with lucid implementation in R.

After his sister's death, Jared Campbell had to get married to keep her adopted children together. Quiet Annie Dawson was a fast favorite of the kids and seemed the perfect choice for an Australian farm wife. Until Jared discovered Annie's shocking secret: the youngest boy was her son. As a teenager, Annie had given up her baby, hoping he would have a better life. Now she had a second chance to be his mother. But when Annie's past was revealed, Jared's own experience with abandonment made it hard for him to accept what Annie had done. Could his wounded heart find healing within his new family?

Who knew a fresh start could be so hard? Not single mom Lisa Marley. She'd made her share of mistakes, but now she just wanted a chance to rebuild trust - and to raise her daughter, Cecily.

Between the challenges of raising three children, his church duties and pursuing a long-cherished dream, he took every opportunity to know her better. As their relationship grew, he wondered if Lisa held the key to his own new beginning, too.

Who was the handsome stranger who'd saved her life - twice? That was what Claire Wilcox wanted to know, especially after she'd impulsively invited the man to stay at her shelter for runaways. She sensed there was more to handyman Nick Andrews than met the eye - there was a great loss this loner was trying to run from. Claire knew what running was all about. A former runaway herself, she'd established a haven for troubled teens. As Nick earned his keep repairing damage to the shelter, he grew closer to Claire, to the kids she cared for…and to the God he'd shut out of his heart. Could Claire's faith begin to fill the spiritual void in his life and give him a new reason to love?

The pint-sized orphan had big, big plans… She longed for Graydon Payne to be her daddy, and Stacy Lucas to be her mommy. And there was only one way to bring them together: by running away….

Now it was time to put their differences aside and join forces on a heart-wrenching mission. Since Gray had last seen Stacy, he had discovered something more powerful than his wealthy family. But it would take more than steadfast faith to locate the missing cherub in the vast Ozark wilderness - and to convince Stacy to give him another chance. It might even take a miracle….
