This paper presents a brief review of sustainability definitions and analyzes ways of designingtaught in our Engineering education system, specifically acknowledging the capitalist, patriarchal, colonial, Western world that much, if not most, of current Engineering practice situates itself within. Included in these frameworks are pluriversal design, co-design, participatory design, and discursive design. Another important topic that will be examined is the dualist perspective embodied in Engineering practice that creates a distinction between “man” and “nature”. While this problem is inherently systemic, our intention is to provide a partial record of our own critical selfreflection,contextualized using critical theory. It is intended as a starting place for settler-descendent NorthAmerican educators to begin to contextualize our own approaches, not as a way for us to guide steps forward, but instead to begin a self-critique of current approaches that need continued work.

Due to the COVID-19 pandemic, course activities pivoted to online learning in 2020. This necessitated a redesign of Systems Design Engineering’s Design Days from a two-day in-person event at the start of term to three shorter online sessions throughout term to prepare and support students during their first term atuniversity. These sessions featured new activities including, an arcade game developed using block coding;a Rube Goldberg virtual ball toss; and the design of a Wi-Fi access point reflector. All activities were designed using principles of effective online learning including, social presence, familiarization with online learning technology, and engaging activities. The online Design Days (Re)Boot Camp ran successfully during Fall 2020, supporting most intended learning outcomes and achieving high initial participation. Continual improvement will focus on sustaining participation, strengthening connections to design and technical concepts, and retaining strong elements upon the return to in-person learning.

Introducing Wavelet techniques into the psychoacoustical analysis of sound signals provides a powerful alternative to standard Fourier methods. In this paper the reformulation of existing psychoacoustical signal parameters using wavelet methods will be explored. A major motivation for this work is that traditional psychoacoustical signal analysis relies heavily on the Fourier transform to provide a frequency content representation of a time signal, but this frequency domain representation is not always accurate; especially for sounds with impactive components. These impactive events can have a more significant contribution to the calculation of psychoacoustical signal parameters by reformulating existing psychoacoustic parameters in the Wavelet domain that are dependent on the Fourier transform. To provide concrete examples of the results simulated “plucked string” sounds are analyzed with analogous Fourier and Wavelet domain signal parameters to demonstrate the difference in performance achieved using Wa...
