Deep Learning For High-Impedance Fault Detection And Classification, Khushwant Rai 2021 The University of Western Ontario

Deep Learning For High-Impedance Fault Detection And Classification, Khushwant Rai

Electronic Thesis and Dissertation Repository

High-Impedance Faults (HIFs) are a hazard to public safety but are difficult to detect because of their low current amplitude and diverse characteristics. Supervised machine learning techniques have shown great success in HIF detection; however, these approaches rely on resource-intensive signal processing techniques and fail in presence of non-HIF disturbances and even for scenarios not included in training data. This thesis leverages unsupervised learning and proposes a Convolutional Autoencoder framework for HIF Detection (CAE-HIFD). In CAE-HIFD, Convolutional Autoencoder learns only from HIF signals by employing cross-correlation; consequently, eliminating the need for diverse non-HIF scenarios in training. Furthermore, this thesis proposes …

Deep Learning Based Music Source Separation, Ryan Henning, Abdullah Choudhry, Ming Ma

SCSU Journal of Student Scholarship

Decades of music exists in the world with no way to find the original multitrack recordings that they are composed of, whether it be a lack of access or just being lost to time. Music source separation is the process of using technology to isolate the individual components of a song after they have been fully arranged and mixed together. These components, or stems, can be the vocals, drums, bass, or any other instrument found in the song. By doing complex analysis on the structure of songs to determine which frequencies or waveform patterns belong to particular sources, a convolutional …

Designing Blended Experiences: Laugh Traders Design Fiction, Brian J. Okeefe

Frameless

The increasing ubiquity of interactions that involve complementary digital content, physical objects, and spaces, brings about new challenges for designers. There is a need to embed designs in legacy systems, whether those are existing physical structures or existing digital platforms. Traditional approaches to product design, interaction design, and user experience design often do not take this new context into account. Many systems do not consider how designers produce new digital and physical experiences that work harmoniously, while supporting new interactions and relationships with people (Imaz and Benyon 2007; Jetter, Geyer, Schwarz & Reiterer 2012).
