This document summarizes a presentation given by Julien Laroche on relational dynamics and rhythmic coordination. The presentation discussed how classical conceptions view time as a linear succession of equal units, whereas behavioral research shows fluctuations are functional and meaningful. An experiment tested how tapping tasks in solo, unilateral, and mutual conditions affected coordination and complexity. Results showed stronger synchronization but more fluctuations in unilateral versus mutual conditions. Individual fractal dynamics also correlated more in the mutual condition, showing how relational dynamics organize individual behaviors. Applications to pathology rehabilitation and music pedagogy were discussed.

Passenger seat is main part of vehicle which has direct effect on her/his convenience. Seat suspension can remove unwanted and harmful vibration if right parameters were selected. Each of human body organs has specific natural frequency. When vehicle vibration reaches to this natural frequency, resonance will occur, and this phenomenon is harmful in long term. Usually lumped models used to predict human body response to vibration. In this paper, via Kitazaki biodynamic model, the seat to head vibration transmissibility was minimized by artificial neural network method. By this method, the optimum spring constant, damper coefficient and mass values were found.

Interactive Animation And Modeling By Drawing - Pedagogical Applications In M...David Bourguignon
Medicine is a discipline where visualization is an essential component of learning. However, the three-dimensional, dynamic structure of the human body poses difficult teaching challenges. There is a need for truly interactive computer tools that will enable students to create and manipulate computer models, not just watch them. We propose dierent approaches with that goal in mind. We were first interested in interactive physically-based animation of anisotropic elastic materials. One possible application scenario is an anatomy course on heart physiology where students can build interactive samples of cardiac muscular tissue. To achieve this, our model exhibits two key features. The first one is a low computational cost that results in high frame rates; the second one is an intuitive system image that ensures easy control by the user. Next, we were interested in interaction in three dimensions using two-dimensional input, either for annotating existing models, or for creating new models; taking advantage of the fact that drawing practice is still considered a fundamental learning method by some anatomy teachers in the French medical school curriculum. Our 3D drawing system has a stroke representation that enables drawing redisplay when the viewpoint changes. Moreover, this representation can be mixed freely with existing polygonal surfaces for annotation purposes. In contrast, our modeling by drawing tool uses information from both stroke geometry and the drawn image, to allow three-dimensional modeling without explicit depth specification.
Weak coupling and broken symmetry: enablers of adaptive complexity - E. Togno...EmmanuelleTognoli
Sixteen hundred sixty-five: Huygens discovers a phenomenon he poetically names "Sympathy of the clocks". It is the ineluctable falling into synchrony by two pendulum clocks, driven to coherence by the imperceptible vibration of the suspension beam they share. Since Huygens' inauguration of the entire field of weakly coupled oscillators, the phenomenon has found countless empirical grounds, including in the behavior of interacting people or fireflies, in coupling within and between brains, in electronic, biological and informational systems. In Huygens' experiment, the tenuous vector of the coupling, the vibration of the wooden beams, is countered by the remarkable symmetry of the two clocks. Nonetheless, we now know that systems with lesser symmetry manage to overcome their difference and coordinate through synchrony and metastability. And since adaptation leads to divergence, with weak coupling of nonidentical parts, nature preserves useful coordination mechanisms well past the perfect unison that Huygens revealed, and that many mechanical systems retain. In this talk, I introduce an experimental model of pendulum oscillators with varying natural frequencies, and I provide an empirical analysis of their coordination behavior. My goal is to showcase interdisciplinary research, expose the insights that data analysis offers and engage a discussion on models. My conclusion will be that more theoretical insights on weak coupling and broken symmetry will help us better understand Complexity in Nature.

Prediction the Biodynamic Response of Seated Human Body to Vibration Using A...MOSTAFAABDEEN1970
The biodynamic response behaviors of seated human body subject to wholebody
vibration have been widely investigated. The biodynamic response
characteristics of seated human subjects have been extensively reported in
terms of apparent mass and driving-point mechanical impedance while seat-tohead
vibration transmissibility has been widely used to characterize response
behavior of the seated subjects exposed to vibration. These functions (apparent
mass, driving-point mechanical impedance) describe “to-the-body” force–motion
relationship at the human–seat interface, while the transmissibility function
describes “through-the-body” vibration transmission properties. The current study
proposed a 4-DOF analytic biomechanical model of the human body in a sitting
posture without backrest in vertical vibration direction to investigate the
biodynamic responses of different masses and stiffness. Following the analytical
approach, numerical technique developed in the present paper to facilitate and
rapid the analysis. The numerical analysis used here applies one of the artificial
intelligence technique to simulate and predict the response behaviors of seated
human body for different masses and stiffness without the need to go through the
analytic solution every time. The Artificial Neural Network (ANN) technique is
introduced in the current study to predict the response behaviors for different
masses and stiffness rather than those used in the analytic solution. The results
of the numerical study showed that the ANN method with less effort was very
efficiently capable of simulating and predicting the response behaviors of seated
human body subject to whole-body vibration.
Scale free dynamics and scale invariance are universal characteristics of complex systems in nature. 1/f or long-range temporal correlations or pink noise is also a self-generated/correlated brain noise that coexists with periodic brain oscillations in a non predominant temporal fashion. For a long time this kind of noise has been ignored in experimental manipulations or analyses because thought to be the expression of instrumental noise. Nowadays, instead, recent evidence speaks in favour of the functional significance of the 1/f and its spatiotemporal organisation at different levels. However, further investigation is needed in order to unveil the relationship between each specific 1/f noise (across individuals, behavioural tasks, across different natural phenomena…). Outline of the lecture: 1. Power-law distributions in nature 2. Types of noise 3. 1/f as a signature of complexity 4. Debate between brain oscillations and noise 5. New perspectives on 1/f: functional significance and temporal organisation.
