[WiE webinar] Intelligent social robots living among us and providing care as we age by Goldie Nejat

Friday 7 June 2024 at 10:00 AM EDT, 4:00 PM CET By Goldie Nejat  (University of Toronto, Canada) Register now using the link below: https://attendee.gotowebinar.com/register/7119922069471803231 Abstract: As the world’s older population significantly increases, dementia is becoming one of the fastest growing diseases, with no cure in sight. Socially assistive robots are a unique disruptive innovation that are becoming a crucial part of everyday society, aiding people in everyday life to meet urgent and immediate assistive needs and help minimize social isolation. This talk will present some of my group’s recent research efforts (asblab.mie.utoronto.ca) in developing intelligent socially assistive robots to improve quality of life and promote independence (aging-in-place) of older adults, including those living with dementia and their care providers. In particular, I will discuss some of my team’s many robots including Brian, Casper, Tangy, Blueberry, Salt and Pepper, and Luke and Leia that have been deployed successfully in human-centred environments from long-term care homes and hospitals to grocery stores to autonomously provide cognitive and social interventions, help with activities of daily living, and lead group recreational activities and therapies. Our novel multimodal interactive robots are serving as assistants to individuals as well as groups of users. Through ...

Automotive Electrical Machine Design: NVH Enhancement Method for High-Speed E-Machines in FEA Simulations

Tuesday 28 May 2024 at 4:00 PM CEST, 10:00 AM EST By Tommaso Bertoncello (Volvo Cars, Sweden) and Ved Acharya (Powersys, USA) Register now using the link below: https://attendee.gotowebinar.com/register/6739375596457667159 Abstract: Noise, Vibration and Harshness (NVH) in rotating electrical machines for automotive is a crucial aspect to consider for a good motor design. The stator teeth's radial and tangential forces induce stator core deformation that cause vibrations and noise in the machine.  The severity of these deformations depends on the vibration mode of force waveforms: lower the vibration mode number, higher the deflection of the stator core and the noise. Hence, designers must select specific spatial and temporal force harmonics and minimize them. By mitigating NVH within the optimization process, designers can streamline iterations, thereby reducing the time-to-prototype significantly. Thus, an accurate way of analysing the force waveforms is needed during the design phase. In this webinar, a novel method of extracting the force harmonics in FEA environment will be presented. Various features for NVH enhancement will be shown, focusing on their influence on force harmonics. Furthermore, an analysis of asymmetrical geometries utilizing the same methodology will be conducted to assess their potential as a viable alternative to skewing in ...
