Special issue on “Qualitative Spatial Reasoning” Preface

In contemporary parlance, qualitative reasoning can be regarded as reasoning about physical systems by exploring their structural properties. Qualitative spatial reasoning, in particular, aims to express non– numerical relationships among spatial objects based on relations such as “in contact with” and “part of”. Its roots include the region-based theories of space of de Laguna [1] and Whitehea...

Special Issue on Speech Processing for Hearing Aids

With the widespread usage of digital hearing aids and increased demands placed on their performance, advanced speech processing techniques are playing a more important role in modern hearing aid systems. Speech processing for hearing aids encompasses a range of topics including signal acquisition, transfer, amplification, transmission, measurement, filtering, parameter estimation, separation, d...

Special issue on spatial moment techniques for modelling biological processes.

Over the last two decades, there has been an increasing awareness of, and interest in, the use of spatial moment techniques to provide insight into a range of biological and ecological processes. Models that incorporate spatial moments can be viewed as extensions of mean-field models. These mean-field models often consist of systems of classical ordinary differential equations and partial diffe...

Guest Editors’ Note—Special Issue on Spatial Audio

Three-dimensional (or spatial) audio is a growing research field that plays a key role in realizing immersive communication in many of today’s applications for teleconferencing, entertainment, gaming, navigation guidance, and virtual reality (VR)/augmented reality (AR). Technologies in spatial sound capture and binaural recording are becoming an add-on module to our mobile devices to capture th...
