... The S-transform (ST) is a popular linear time-frequency (TF) transform with hybrid characteristics from the short-time Fourier transform (STFT) and the wavelet transform. It enables a multi-resolution TF analysis and returns globally referenced local phase information, but its expensive computational requirements often overshadow its other desirable features. In this paper, we develop a fully discrete ST (DST) with a controllable TF sampling scheme based on a filter-bank interpretation. The presented DST splits the analyzed signal into subband channels whose bandwidths increase progressively in a fully controllable manner, providing a frequency resolution that can be varied and made as high as required, which is a desirable property for processing oscillatory signals lacked by previously presented DSTs. Thanks to its flexible sampling scheme, the behavior of the developed transform in the TF domain can be adjusted easily; with specific parameter settings, for example, it samples the TF domain dyadically, while by choosing different settings, it may act as a STFT. The spectral partitioning is performed through asymmetric raised-cosine windows whose collective amplitude is unitary over the signal spectrum to ensure that the transform is easily and exactly invertible. The proposed DST retains all the appealing properties of the original ST, representing a local image of the Fourier transform; it requires low computational complexity and returns a modest number of TF coefficients. To confirm its effectiveness, the developed transform is utilized for different applications using real-world and synthetic signals.

... Audio data comprising naturally-occurring spoken discourse in support of paper on future expression in Gã. Due largely to the overwhelming frequency of the temporal function in the discourse data, I maintain that the primary function of bàá- is as a tense marker and not a modal, as has been suggested by Dakubu (2008). I show that àá- is now reserved primarily for coding epistemic modality. Gã is therefore unique among Kwa languages, which have been said to be tenseless. This study uncovers previously unreported non-temporal uses of bàá- and clarifies the situation regarding the semantic differences between the two markers. Reference Dakubu, Mary Esther Kropp 2008.

... Labeled dataset of frog calls recorded at Yasuní National Park using directional and omni-directional microphones. We trained a Bayesian classifier with Gaussian Mixture Models and applied it to study the audio in Unidentified Long Recordings. The results of the analysis are in the related article. We showed that the application of a frog-call recognition algorithm allows the estimation of presence-absence of the trained subset of species in real-world recordings of an actual amphibian monitoring made in the wild.

... The primary question investigated was ‘How do Deakin University academic staff perceive the role of liaison librarians?’ This investigation was conducted to collect and analyze data to better understand how academics at Deakin University perceive the role of librarians, regardless of whether they are faculty liaison or service desk based, and to help inform how liaison librarians at Deakin University undertake their role. Focus groups were formed by inviting academics and selected library staff to participate in an activity, during which they created an artifact – a visual representation of the role of a liaison librarian using mixed media, including drawing and collage. During an unstructured interview section, participants gave an oral explanation of their work in order to make meaning of their creative representation. This was recorded, and de-identified, for data analysis.
