This special issue of autonomous agents and multi-agent systems sought research articles that discuss relevant topics for the current trends in research on software agents and agent-based software systems. Topics of interest included techniques and technologies to engineer agent-based software systems, as well as languages, frameworks, and infrastructures broadly related to software agents and agent-based software systems.

This paper investigates the use of group goals and plans as programming abstractions that provide explicit constructs for goals and plans involving coordinated action by groups of agents, with a focus on the BDI agent model. We define a group goal construct, which specifies subgoals that the group members must satisfy for the group goal to succeed, subject to timeouts on the members beginning work on the goal, and then completing their subgoals. A group plan containing one or more group goals can be dynamically distributed amongst a set of agents and jointly executed without a need for explicit coordinating communication between agents. We define formal semantics that model the coordination needed to determine a group goal's success or failure as updates to a shared state machine for the group goal. We implement the semantics directly as rewrite rules in Maude, and verify using LTL model checking that the intended coordination behaviour is achieved. An implementation of group plans and goals for the Jason agent platform is also described, based on an integration of Jason with the ZooKeeper coordination middleware via a set of generic Jason plans supporting group goals, and the Apache Camel integration framework. A evaluation of the performance of this implementation is presented, showing that the approach is scalable.

The book presents research that contributes to the development of intelligent dialog systems to simplify diverse aspects of everyday life, such as medical diagnosis and entertainment. Covering major thematic areas: machine learning and artificial neural networks; algorithms and models; and social and biometric data for applications in human–computerinterfaces, it discusses processing of audio-visual signals for the detection of user-perceived states, the latest scientific discoveries in processing verbal (lexicon, syntax, and pragmatics), auditory (voice, intonation, vocal expressions) and visual signals (gestures, body language, facial expressions), as well as algorithms for detecting communication disorders, remote health-status monitoring, sentiment and affect analysis, social behaviors and engagement. Further, it examines neural and machine learning algorithms for the implementation of advanced telecommunication systems, communication with people with special needs, emotion modulation by computer contents, advanced sensors for tracking changes in real-life and automatic systems, as well as the development of advanced human–computerinterfaces. The book does not focus on solving a particular problem, but instead describes the results of research that has positive effects in different fields and applications.

This textbook presents an introduction to signal processing for audio applications. The author’s approach posits that math is at the heart of audio processing and that it should not be simplified. He thus retains math as the core of signal processing and includes concepts of difference equations, convolution, and the Fourier Transform. Each of these is presented in a context where they make sense to the student and can readily be applied to build artifacts. Each chapter in the book builds on the previous ones, building a linear, coherent story. The book starts with a definition of sound and goes on to discuss digital audio signals, filters, The Fourier Transform, audio effects, spatial effects, audio equalizers, dynamic range control, and pitch estimation. The exercises in each chapter cover the application of the concepts to audio signals. The exercises are made specifically for Pure Data (Pd) although traditional software, such as MATLAB, can be used. The book is intended for students in media technology bachelor programs. The book is based on material the author developed teaching on the topic over a number of years.

This book focuses on the fundamentals and recent advances in RGB-D imaging as well as covering a range of RGB-D applications. The topics covered include: data acquisition, data quality assessment, filling holes, 3D reconstruction, SLAM, multiple depth camera systems, segmentation, object detection, salience detection, pose estimation, geometric modelling, fall detection, autonomous driving, motor rehabilitation therapy, people counting and cognitive service robots. The availability of cheap RGB-D sensors has led to an explosion over the last five years in the capture and application of colour plus depth data. The addition of depth data to regular RGB images vastly increases the range of applications, and has resulted in a demand for robust and real-time processing of RGB-D data. There remain many technical challenges, and RGB-D image processing is an ongoing research area. This book covers the full state of the art, and consists of a series of chapters by internationally renowned experts in the field. Each chapter is written so as to provide a detailed overview of that topic. RGB-D Image Analysis and Processing will enable both students and professional developers alike to quickly get up to speed with contemporary techniques, and apply RGB-D imaging in their own projects.

This open access book offers an original interdisciplinary overview of the role of haptic feedback in musical interaction. Divided into two parts, part i examines the tactile aspects of music performance and perception, discussing how they affect user experience and performance in terms of usability, functionality and perceived quality of musical instruments. Part ii presents engineering, computational, and design approaches and guidelines that have been applied to render and exploit haptic feedback in digital musical interfaces. Musical hapticsintroduces an emerging field that brings together engineering, human-computerinteraction, applied psychology, musical aesthetics, and music performance. The latter, defined as the complex system of sensory-motor interactions between musicians and their instruments, presents a well-defined framework in which to study basic psychophysical, perceptual, and biomechanical aspects of touch, all of which will inform the design of haptic musical interfaces. Tactile and proprioceptive cues enable embodied interaction and inform sophisticated control strategies that allow skilled musicians to achieve high performance and expressivity.
