Aspects of song interaction between the closely related bush cricket genera Platycleis and Metrioptera
Published 1978“…This study Is concerned with the behavioural and ecological aspects of the acoustic interaction that occurs when two bush cricket species, Platycleis albopunctata and Metrioptera roeselii. sing together. The effects of the interaction are predominantly one-way and result in inhibition of singing activity by albopunctata, or a change in its song pattern. …”

Novel opto-electronic and plastic fibre sensors
Published 1998“…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”

Imagined cities (Voicescapes)
Published 2015“…RESEARCH QUESTIONS While the field of vocal studies has progressively emphasised the interdisciplinary potential of vocal performance (Novak, 2015; Thomaidis and Macpherson, 2015), the idea of durational/installational live singing is still a little explored subject. • How may live singing be used to create a durational, post-dramatic exhibit? …”
