Autonomous unmanned air vehicles (UAVs) are critical to current and future military, civil, and commercial operations. Despite their importance, no previous textbook has accessibly introduced UAVs to students in the engineering, computer, and science disciplines--until now. Small Unmanned Aircraft provides a concise but comprehensive description of the key concepts and technologies underlying the dynamics, control, and guidance of fixed-wing unmanned aircraft, and enables all students with an introductory-level background in controls or robotics to enter this exciting and important area. The authors explore the essential underlying physics and sensors of UAV problems, including low-level autopilot for stability and higher-level autopilot functions of path planning. The textbook leads the student from rigid-body dynamics through aerodynamics, stability augmentation, and state estimation using onboard sensors, to maneuvering through obstacles. To facilitate understanding, the authors have replaced traditional homework assignments with a simulation project using the MATLAB/Simulink environment. Students begin by modeling rigid-body dynamics, then add aerodynamics and sensor models. They develop low-level autopilot code, extended Kalman filters for state estimation, path-following routines, and high-level path-planning algorithms. The final chapter of the book focuses on UAV guidance using machine vision. Designed for advanced undergraduate or graduate students in engineering or the sciences, this book offers a bridge to the aerodynamics and control of UAV flight.

With fascination, Davie and his friend Geordie watch the arrival of a new boy, Stephen Rose, in their town. He seems to have come from nowhere, and when he arrives to live with his distant aunt, the local Crazy Mary, no one envies his new home. But perhaps he's the answer to Davie and Geordie's prayers - a secret weapon in their war against monstrous Mouldy and his gang. Intrigued, Davie and Geordie befriend Stephen. But they are heading innocently down a path that brings with it a monster of an entirely unexpected nature. Their encounter with the mysterious Stephen is as incredible as it is menacing, and as the true story of Stephen's past slowly emerges, Davie's life is changed for ever... A stunning novel from the author of the modern children's classic Skellig - winner of the Carnegie Medal and the Whitbread Children's Book Award. David Almond is also winner of the 2010 Hans Christian Andersen award.

This hands-on, practical guide for ESL/EFL teachers and teacher educators outlines, for those who are new to doing action research, what it is and how it works. Straightforward and reader friendly, it introduces the concepts and offers a step-by-step guide to going through an action research process, including illustrations drawn widely from international contexts. Specifically, the text addresses: action research and how it differs from other forms of research the steps involved in developing an action research project ways of developing a research focus methods of data collection approaches to data analysis making sense of action research for further classroom action. Each chapter includes a variety of pedagogical activities: Pre-Reading questions ask readers to consider what they already know about the topic Reflection Points invite readers to think about/discuss what they have read action points ask readers to carry out action-research tasks based on what they have read Classroom Voices illustrate aspects of action research from teachers internationally Summary Points provide a synopsis of the main points in the chapter Bringing the 'how-to' and the 'what' together, Doing Action Research in English Language Teaching is the perfect text for BATESOL and MATESOL courses in which action research is the focus or a required component.
