SUMMARY:Post-grazing dynamics of a vibro-impacting energy generator
DESCRIPTION:Larissa Serdukova\, PDRA in Mathematics of Planet Earth – Project TiPES\, will be presenting ‘Post-grazing dynamics of a vibro-impacting energy generator’ as part of the University of Bath’s AIMS seminar series on Tuesday 9th February at 1.15pm. \nZoom Meeting\nhttps://bath-ac-uk.zoom.us/j/98901674720?pwd=VXFac3Vqc1o2SU85WG9Gc29EQ\nMeeting ID: 989 0167 4720\nPasscode: 641774 \nThe motion of a forced vibro-impacting inclined energy harvester is investigated in parameter regimes with asymmetry in the number of impacts on the bottom and top of the device. This motion occurs beyond a grazing bifurcation\, at which alternating top and bottom impacts are supplemented by a zero velocity impact with the bottom of the device. For periodic forcing\, we obtain semi-analytical expressions for the asymmetric periodic motion with a ratio of 2:1 for the impacts on the device bottom and top\, respectively. These expressions are derived via a set of nonlinear maps between different pairs of impacts\, combined with impact conditions that provide jump discontinuities in the velocity. Bifurcation diagrams for the analytical solutions are complemented by a linear stability analysis around the 2:1 asymmetric periodic solutions and are validated numerically. For smaller incline angles\, a second grazing bifurcation is numerically detected\, leading to a 3:1 asymmetry. For larger incline angles\, period doubling bifurcations precede grazing bifurcations. The converted electrical energy per impact is reduced for the asymmetric motions\, and therefore less desirable under this metric.

SUMMARY:Conference: Linear Response: Rigorous Results and Applications
DESCRIPTION:Conference: Linear Response: Rigorous Results and Applications\n25 – 29 January 2021\nBernoulli Center\, EPFL\, Lausanne (online) \nTransfer operators have been used to study rare and extreme events in dynamical systems and the linear – or nonlinear – response of systems to perturbations\, including applications to climate dynamics. This conference brings together experts from both theoretical and applied aspects of these studies\, also in the presence of singularities. \nClick here to register online https://bernoulli.epfl.ch/events/1507 \nProfessor Valerio Lucarini\, Director of the Centre for the Mathematics of Planet Earth (CMPE)\, will be one of the speakers.

SUMMARY:Workgroup on Climate-Statistical Mechanics - LSCE/SPEC
DESCRIPTION:Workgroup on Climate-Statistical Mechanics – LSCE/SPEC\nMonday Jan 11th 2021\, 13.00 London Time/14.00 Paris time\, Seminar \nValerio Lucarini (University of Reading)\n“Fingerprinting Heatwaves and Cold Spells and Assessing Their Response to Climate Change using Large Deviation Theory” \nExtreme events provide relevant insights on the dynamics of the climate system and their understanding is key to defining useful strategies for mitigating the impact of climate variability and climate change. By applying large deviation theory to the output of a state-of-the-art climate model\, we define the climatology of persistent heatwaves and cold spells in some key target regions of the planet by constructing empirically the corresponding rate functions for the surface temperature\, and we assess the impact of increasing CO2 concentration on such persistent anomalies. In particular\, we can better understand the increasing hazard associated to heatwaves in a warmer climate. We show that two 2010 high impact events – summer Russian heatwave and winter Dzud in Mongolia – are associated with atmospheric patterns that are exceptional compared to the typical ones\, but typical compared to the climatology of extreme events. Finally\, we propose an approximate formula for describing large and persistent temperature fluctuations from easily accessible statistical properties. \nM. Galfi and V.

SUMMARY:Workshop on Critical Transitions in Complex Systems 2020 (online)
DESCRIPTION:Workshop on Critical Transitions in Complex Systems 2020 (online)\, 29th – 31st July 2020 \nComplex systems research has been at the forefront of scientific priorities for some time and many very interesting phenomena have been identified and explored in the context of a wide variety of applications. This workshop is part of a series\, reflecting on an emerging movement to develop a mathematical theory for sudden changes in the dynamical behaviour of complex systems\, so-called critical transitions. The prospect to develop reliable early-warning signals for such critical transitions is potentially far-reaching since these could lead to better control strategies to avoid or diminish the effect of catastrophes. \nConfirmed speakers include: \nThomas Bury (McGill University\, Canada)\nKwang-Hyun Cho (Korea Advanced Institute of Science and Technology\, South Korea)\nMark Dekker (University of Utrecht\, The Netherlands)\nDeniz Eroglu (Kadir Has University\, Turkey)\nPeter Ditlevsen (Niels Bohr Institute\, Denmark)\nMarino Gavidia (University of Luxembourg\, Luxembourg)\nFederico Graceffa (Imperial College London\, UK)\nYoshito Hirata (University of Tsukuba\, Japan)\nFrancoise Kemp (University of Luxembourg\, Luxembourg)\nChristian Kuehn (TU Munich\, Germany)\nJuergen Kurths (Potsdam Institute for Climate Impact Research and Humboldt University Berlin\, Germany)\nValdimir Levin (University of Luxembourg\, Luxembourg)\nTiejun Li (Peking University\, China)\nWei Lin (Fudan University\, China)\nRui Liu (South China University of Technology\, China)\nIacopo Longo (TU Munich\, Germany)\nValerio Lucarini (University of Reading\, UK)\nStefano Magni (University of Luxembourg\, Luxembourg)\nTadayoshi Matsumori (Toyota\, Japan)\nGuillermo Olicon-Mendez (Imperial College London\, UK)\nJulian Newman (University of Exeter\, UK)\nMakito Oku (University of Toyama\, Japan)\nGreg Pavliotis (Imperial College London\, UK)\nTiago Pereira (University of Sao Paulo\, Brazil)\nDaniele Proverbio (University of Luxembourg\, Luxembourg)\nMartin Rasmussen (Imperial College London\, UK)\nCourtney Quinn (CSIRO\, Hobart\, Australia)\nFlavia Remo (University  of Jena\, Germany)\nYuzuru Sato (Hokkaido University\, Japan)\nMarten Scheffer (Wageningen University\, Netherlands)\nDidier Sornette (ETH Zurich\, Switzerland ) \nFor further information and provisional schedule for the online workshop\, please visit https://bit.ly/workshopcriticaltransitions2020. Registration is compulsory and can be done on the workshop webpage.
