Classifying Laughter: An Exploration Of The Identification and Acoustic Features of Laughter Types
… proportion of voiced laughter vs. silence). The audio analysis indicates acoustic features of laughter are not overall significantly different amongst the three categories and therefore suggests social context, including proximal language and visual cues, predominantly explains the …

Machine-Learning-Based Non-Destructive Evaluation of Refractory Anchor Welds via Analysis of Percussion-Induced Acoustic Signals
… machine learning (ML) and percussion-induced audio analysis to assess weld quality. A custom weld plate was fabricated containing both properly welded and intentionally flawed refractory anchors. Controlled mechanical impacts—using tools such as a hammer and chisel—were applied to the exposed …

Multimodal Recognition of Social Behaviors and Personality Traits in Small Group Interaction
In recent years, the automatic analysis of human behaviour has been attracting an increasing amount of attention from researchers because of its important applicative aspects and its intrinsic scientific interest. In many technological fields (pervasive and ubiquitous computing, multimodal …

The history and heritage of the Pinghu Pipa School
… combining historical ethnomusicology, archival analysis of critical scores, digital audio analysis of performance parameters (e.g., pitch, dynamics, tempo) and ethnographic fieldwork with contemporary inheritors. The analysis is structured around five pivotal historical phases, tracing the …

On the data hiding theory and multimedia content security applications
… their applications in video,, image and audio. Most available embedding schemes are based on direct Spread Sequence (SS) modulation. A small value pseudo random signature sequence is embedded into the host signal and the information is extracted via correlation. The correlation detection …

A perceptually motivated approach to timbre representation and visualisation.
… research from experimental psychology and audio signal analysis has deepened our understanding of the perception, description, and measurement of musical timbre, suggesting the possibility of more exact forms of representation that directly reference low-level descriptors of the audio …

The anti-racist state: an investigation into the relationship between representations of 'racism', anti-racist typification and the state : a 'Scottish' case study
… provides a robust geo-political framework for analysis in that there is explicit recognition that the problem of racism in Scotland has been neglected historically. We have moved from a social policy context in which racism was not given sufficient attention by the Scottish arm of the British …

An Investigation into the Use of Artificial Intelligence Techniques for the Analysis and Control of Instrumental Timbre and Timbral Combinations
… thesis, we explore harnessing techniques for the analysis and control of instrumental timbre and timbral combinations. This thesis begins with investigating the link between musical timbre, auditory perception and psychoacoustics for sounds emerging from instrument mixtures. It resulted in …
