This book is focused on geometrical models of robot mechanisms. Rotation and orientation of an object are described by Rodrigues's formula, rotation matrix and quaternions. Pose and displacement of an object are mathematically dealt with homogenous transformation matrices. The geometrical robot model is based on Denavit Hartenberg parameters. Direct and inverse model of six degrees of freedom anthropomorphic industrial robots are also presented.
This supplementary introductory text for courses in robotics or industrial robotics requires minimal knowledge of physics and mathematics. It treats many fundamental subjects in robotics and includes a glossary in English, French and German.
This book provides a comprehensive introduction to the area of robot mechanisms, primarily considering industrial manipulators and humanoid arms. The book is intended for both teaching and self-study. Emphasis is given to the fundamentals of kinematic analysis and the design of robot mechanisms. The coverage of topics is untypical. The focus is on robot kinematics. The book creates a balance between theoretical and practical aspects in the development and application of robot mechanisms, and includes the latest achievements and trends in robot science and technology.
This book presents the author’s personal overview of Speech Prosody, and in particular the different areas in which he has been especially interested over the last few decades. These include the acoustics of speech prosody, the relationship between lexical and non-lexical prosody, the phonology of prosody, the modeling of rhythm and of melody, and the central question of the various and at times quite mysterious ways in which prosody contributes to the interpretation of an utterance. All these aspects are then brought together in an account of the description of intonation systems, and how these differ across languages.
This reference text covers the fundamental knowledge and principles of functional electrical stimulation (FES) as applied to the spinal cord injured (SCI) patient. The principles of FES application and basic biomechanical issues related to FES in SCI are stressed. The fundamentals regarding patient selection criteria, indication, contraindications, and descriptions of procedures are clearly presented. Also included are the fundamentals and rationale of gait restoration with patient selection, control strategies, and the synthesis of gait sequences with trends in the field. Each chapter contains numerous references to the FES literature for the reader to easily evaluate and extend his knowledge in the area of interest. Biomedical and rehabilitation engineering professionals and researchers for medical doctors, physical therapists, and orthotists will find this publication invaluable.
This is a down-to-earth, 'how to do it' textbook on the making of dictionaries. Written by professional lexicographers with over seventy years' experience between them, the book presents a step-by-step course for the training of lexicographers in all settings, including publishing houses, colleges, and universities world-wide, and for the teaching of lexicography as an academic discipline. It takes readers through the processes of designing, collecting, and annotating a corpus of texts; shows how to analyse the data in order to extract the relevant information; and demonstrates how these findings are drawn together in the semantic, grammatical, and pedagogic components that make up an entry....
This collection of contemporary examples of chemistry in action highlights the fundamental role of chemical principles in governing everyday experiences. It is presented in a question-and-answer format of topical subjects.
Historical linguistic theory and practice consist of a large number of chronological "layers" that have been accepted in the course of time and have acquired a permanence of their own. These range from neogrammarian conceptualizations of sound change, analogy, and borrowing, to prosodic, lexical, morphological, and syntactic change, and to present-day views on rule change and the effects of language contact. To get a full grasp of the principles of historical linguistics it is therefore necessary to understand the nature of each of these "layers". This book is a major revision and reorganization of the earlier editions and adds entirely new chapters on morphological change and lexical change, as well as a detailed discussion of linguistic palaeontology and ideological responses to the findings of historical linguistics to this landmark publication.
Mixed matrix membranes (MMMs) have attracted a large amount of interest in research laboratories worldwide in recent decades, motivated by the gap between a growing interest in developing novel mixed matrix membranes by various research groups and the lack of large-scale implementation. This Special Issue contains six publications dealing with the current opportunities and challenges of mixed matrix membranes development and applications to solve environmental and health challenges of the society of 21st century.
