Community concerns over resource extraction and public anxieties about insertion of waters and waste are creating a growing societal unease about geological exploitation of the subsurface. Addressing these emergent areas of socially contested subsurface geoscience is difficult for many academic and industrial geologists, not least because translating unfamiliar concepts of the geological subsurface between stakeholders presents a challenge. This paper proposes a novel approach to engaging publics with geological issues: the GeoCube. Combining 3D Participatory Mapping with the Mental Models approach, the GeoCube allows participants to explore complex geological ideas. The GeoCube method, developed for a UK study in a Cornish mining village, revealed the ways that experts and non-experts conceptually penetrate the landscape surface to the invisible geological subsurface, highlighting the lack of similarity these two groups demonstrate, allowing communicators to better understand how to bridge the gap.
A method of allowing pitch preservation of sound with variable-rate video playback is suggested. This is an important factor in monitoring of audio content for cueing purposes. Methods of separately considering a signal's frequency and time representations are considered with a view to performing time-scale modification with preservation of local periodicity (pitch).Particular emphasis is placed upon granulation in time of a sampled source -a technique based upon Dennis Gabor's landmark papers in 1946 and 1947 and developed in the field of computer music. This relatively simple method requires no prior signal analysis and is therefore a less computationally expensive method of achieving the goals stated above. This is an important point considering the need for real-time implementation.The process does however introduce some distortion, and investigation into how this may be minimised is necessary to produce acceptable results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
