Book Description
Extended object tracking deals with estimating the shape and pose of an object based on noisy point measurements. This task is not straightforward, as we may be faced with scarce low-quality measurements, little a priori information, or we may be unable to observe the entire target. This work aims to address these challenges by incorporating ideas from active contours and exploiting information from negative measurements, which tell us where the target cannot be.

Book Description
This work is concerned with the simultaneous tracking and shape estimation of a mobile extended object based on noisy sensor measurements. Novel methods are developed for coping with the following two main challenges: i) The computational complexity due to the nonlinearity and high-dimensionality of the problem, and ii) the lack of statistical knowledge about possible measurement sources on the extended object.

Book Description
Inspired by human perception, novel research into the sub-domain of robotic perception, known as extended object tracking, is presented. This research is motivated by the practical challenges of deploying robot driven cars (aka robocars, self-driving cars, autonomous road vehicles, etc.) into the existing transportation infrastructure alongside human-controlled vehicles. In this vein, arbitrary, uncooperative extended objects maneuvering in close proximity to the ego vehicle are considered, without a priori knowledge of the environment (e.g. road structure, traffic laws, etc.) or the objects to be tracked (e.g. controls, intent, shape, size, type, etc.). The novel approaches presented here are primarily aimed at improving the precision and accuracy of extended object tracking by mitigating the inherent information loss associated with interpreting sensor data returned from arbitrary extended objects. Specifically, a rigorous probabilistic occlusion model is derived for identifying and fusing negative information inherently present in sensor data; information that is heavily leveraged by humans, but largely ignored by robots. Further, a rigorous estimation framework is proposed for estimating the detailed shape of extended objects jointly with their kinematics; detailed object shape estimates enable explicit sensor models, which, in turn, engender improved tracking precision. Additionally, a hierarchical tracking framework is proposed for dynamically allocating computational resources in proportion to an objects continuously changing relevance to the ego robot task, as defined by novel probabilistic object relevancy metrics. As a result, at any given time, objects considered to be of central importance to the ego robot task are tracked with relatively complex, high-precision methods, while objects deemed merely peripheral to the ego robot task are tracked with relatively low complexity, low precision methods; a direct analog to the human concepts of attention and focus in allocating finite cognitive resources. The proposed work is evaluated via simulation and experiments involving Cornell University's autonomous Chevy Tahoe, Skynet, demonstrating that non-traditional sensor models are necessary for high precision tracking of arbitrary extended objects, and that humans are worth emulating en route to this goal.

Book Description
The International Symposium of Robotics Research (ISRR) continues to be the premiere meeting of the International Foundation of Robotics Research (IFRR). The 13th International Symposium of Robotics Research took place Novemb3r 26-29, 2007, in Hiroshima, Japan, and was organized by the two editors of this book. This volume brings a collection of a broad range of topics in robotics. The content of these contributions provides a wide coverage of the current state of robotics research: the advances and challenges in its theoretical foundation and technology basis, and the developments in its traditional and novel areas of applications. Historically, the proceedings of the ISRR have featured ground-breaking work of the highest caliber, which influenced generations to come. The present volume promises to be no exception. The collection of scientific articles in this volume provides new insights to important problems in robotics, written by some of the leaders in the field.

Book Description
We discuss theory and application of extended object tracking. This task is challenging as sensor noise prevents a correct association of the measurements to their sources on the object, the shape itself might be unknown a priori, and due to occlusion effects, only parts of the object are visible at a given time. We propose an approach to track the parameters of arbitrary objects, which provides new solutions to the above challenges, and marks a significant advance to the state of the art.

Book Description
Tutorial Guide to AutoCAD 2015 provides a step-by-step introduction to AutoCAD with commands presented in the context of each tutorial. In fifteen clear and comprehensive chapters, author Shawna Lockhart guides readers through all the important commands and techniques in AutoCAD 2015, from 2D drawing to solid modeling and finally finishing with rendering. In each lesson, the author provides step-by-step instructions with frequent illustrations showing exactly what appears on the AutoCAD screen. Later, individual steps are no longer provided, and readers are asked to apply what they've learned by completing sequences on their own. A carefully developed pedagogy reinforces this cumulative-learning approach and supports readers in becoming skilled AutoCAD users. Tutorial Guide to AutoCAD 2015 begins with three Getting Started chapters that include information to get readers of all levels prepared for the tutorials. The author includes tips that offer suggestions and warnings as you progress through the tutorials. Key Terms and Key Commands are listed at the end of each chapter to recap important topics and commands learned in each tutorial. Also, a glossary of terms and Commands Summary list the key commands used in the tutorials. Each chapter concludes with end of chapter problems providing challenges to a range of abilities in mechanical, electrical, and civil engineering as well as architectural problems.
