At LADHYX Polytechnique Paris (the MIT of France ) Jean-Marc Chomaz' Hydrodynamics lab has a wall-scale mist array with hundreds of straws to smooth and focus flow, plus fans driving mist over their water chambers in plexi modules. each module is about 50cm cube, one face w straws. entire wall is about 3m x 3m

it can puff out laminar flows of mist clear across a room about 6m or "discrete" person-sized letters.

it's bordered by fans that protect the formed mist from stray winds so that it can also work outdoors to some extent.

Chomaz and I thought we could collaborate by connecting his mist instruments to sc.

From Pinar Sefkatli (Universiteit van Amsterdam):

 research publication City Rhythm: Logbook of an Exploration.

 

City Rhythm research was started in 2016 by Prof. dr. Caroline Nevejan, in collaboration with AMS Institute, 6 Dutch cities (Den Haag, Rotterdam, Zaanstad, Zoetermeer, Helmond en Amsterdam), Amsterdam Health and Technology Institute (ahti) and with the students from LDE Minor Responsible Innovation. The research on rhythms in the physical world and in the data world showed that focusing on rhythm and on dynamics in neighbourhoods and in datasets creates new design spaces that can generate un-expected solutions.

 

Thanks to the research grant we received from the Dutch Scientific Research Organisation (NWO), the research will proceed for four more years. The next phase of the research, Designing Rhythms for Social Resilience, will focus on the South-East district of Amsterdam (Amsterdam Zuidoost). DRSR will explore more deeply the rhythms of the neighbourhood from architectural and data perspectives with a PhD researcher from both disciplines, with the main goal of making conclusions on social safety and resilience.

 

We hope that you find the findings of our research inspiring, and that you can get an idea about the upcoming research which will start on July 2018. The publication is also available online, which can be found on TU Delft Architecture Faculty’s books catalogue, BK Books

 


Best wishes,
Pinar Sefkatli

As a first pass to composing relations between people's activity to ecosystem activity…I’m thinking about exemplars of ensemble movements, but under two optics: (1)what people would naturally do as they encounter such a structure in an art event, and (2) ensemble movement that kinetically (formally) happens to resonate with some of the behavior that I see up into the ecosystem,

Exemplar A in people ensemble movement : people start filling up the space, when it has been empty for awhile.

Exemplar A’ in ecosystem movement : all the stuff that happens in transition from night to dawn.

Exemplar B in people ensemble movement : 
People have been milling around for awhile, driving the activity-clock*,  but then they begin to settle down in place (presence under the sky > 1** ).
(But after a while, that activity-clock’s acceleration (second time derivative of clock value) starts to fall to zero)

Exemplar B' in ecosystem movement : a storm builds, leaves silver as they turn under the wind, particles begin to be driven by chaotic wind, in addition to the movement of the leaves.

Of course, in these examples A’ is correlated to A, and B’ to B.   That’s a compositional decision.
The correlation is not fully deterministic, but correlated enough to give Serra a sense of legible response to people activity.

In order to make palpable that there are relations between one self’s activity / presence and the ecosystem, that one is in fact part of the ecosystem, some direct 1-1 logic is necessary, such as:

Exemplars C + C': each person’s movement perturbs the plants corresponding to their location, as if the wake of their passage brushes aside those leaves

I know that as a rule, we do not want to build only 1-1 logics into our piece, bc then that would be merely “interactive art.”  On the other hand, I’d like to avoid the illegibility of "complex systems."   Beesley’s hylomorphic “forests” of fronds: although his installation(s) exhibit complex behavior that has some algorithmic relation to inhabitants' presence and activity as well as the fronds' own states.  Bur after the initial charm wore off, I got bored because (1) the activity was homogeneous over time, (2) the complexity seemed randomly related to my activity.  (He explained that indeed there was a randomizer.)

* activity-clock is a Max patch that has an integer value.  It increments at a default rate per clock time.   However degree of motion (or any parameter derived from sensor data reflecting degree of activity ) increments or decrements that rate.   This simply patch could be re-written as an exercise in elementary Max.    I’d like to use it to drive certain transitions or behaviors in place of simple clocks or line or metro.

** presence can be calibrated so that 1.0 corresponds to 1 human body’s worth of occupancy under the field of view of the camera.   Thus stray smaller objects could sum up to 1.   Similarly degree of motion should be scaled so that 1.0 corresponds to the activity of one person walking about at a pace that we set experimentally by walking under Serra ourselves.

When I see you today, maybe we can start with a quick walk thru of all the different states of behaviour of the ecosystem.  Then we can bought out a bunch of human ensemble activities that we expect, then some transitions corresponding to the emergence of those ensemble activities…  (Every correlation will be naturally continuous.  We can make them seem more triggered simply by changing the response curve to be more like a step function.)

Some obvious human ensemble activities:

D. People move such that there is a general drift along one particular vector.

E. People start to move in a big circle, clockwise or counter-clockwise, with an angular velocity.

F. Gather-Scatter (how closely people bunch together): Connor’s utility.

Just as culture is underdetermined by (vulgar) economics, and metaphor underdetermined by syntax, rhythm as a special case of ontogenesis and individuation is underdetermined by meter.   This is too abstract.   So, listen for the constantly shifting rhythms between the sound, the breathing, the tensions in the performing body which you feel if you’ve learned play the instrument, against the regular meter.

• Sainkho Namtchylak 
Night Birds (1992)
http://epc.buffalo.edu/sound/mp3/ethno/sainkho/mp3/01.mp3
The longing and elasticity of this is not the same as metric regularity.


• A moving interpretation of the Bach Chaconne performed recently by a friend’s daughter Taiga (Ultan) on flute (starting at 3:08)


Listen for how she must negotiate her breathing against the uninterrupted singing line.   The Chaconne is a masterwork of implied voices.  For the violinist it’s already a great challenge to suggest and carry multipleimplied voices sliding across each other with shifting forces (rhythm!).  It’s an even greater challenge for the breathing flutist.  This young performer accomplishes it with sensitivity. 

( To hear one of the most wonderful performances of this in canonical form — for solo violin: Itzhak Perlman. )


•  Brahms : String Quartet No.1 In C Minor Op.51 No.1 - 1. Allegro ( Emerson String Quartet)

Listen for the elasticity which emerges from the interplay of swelling and fading voices, and the constantly shifting accenting (on top of the metric pulse)  The metric is a background grid that does not (and ought not) constrain the continuous multivalent shifts to fixed discrete choices.

• Example: In Mathematica: Play[|Riemann zeta function|]
This sounds totally otherworldly, not self-similar !, not predictable and not random!!


Multiscale self-similarity — “fractals”in pop literature — is just recursive regularity.   Pavan has some subtle ideas, based on dynamical systems theory, about signatures of human intention in movement, that are neither simple sums of periodic functions nor uniformly random processes.   There are connections between those ideas and spectral theory of operators, I think.  Worth discussion at multiple registers, artistic/ expressive, philosophical, as well as mathematical!

Adam, Pavan, PM me if you’d be ok with being added to this personal rhythm email list…

Abstract or Description


This introduction charts several of rhythm's various returns as a way of laying out the theoretical and methodological field in which the articles of this special issue find their place. While Henri Lefebvre’s rhythmanalysis is perhaps familiar to many, rhythm has appeared in a wide repertoire of guises, in many disciplines over the decades and indeed the centuries. This introduction attends to the particular roles of rhythm in the formation of modernity ranging from the processes of industrialization and the proliferation of new media technologies to film and literary aesthetics as well as conceptualizations of human psychology, social behaviour and physiology. These are some of the historical antecedents to the contemporary understandings of rhythm within body studies to which most of the contributions to this issue are devoted. In this respect, the introduction outlines recent approaches to rhythm as vibration, a force of the virtual, and an intensive excess outside consciousness.

I don't have access to respond to the posthaven blog, so I'm sending it directly to you....

Your questions made me think of meta-stability and Simondon... I don't know if if I'm off in left field but here are my two cents' worth... Gotta say though that f is not just any (differentiable) scalar function… it's a nice way at "inducing" continuity where the underlying may not have it..

Yes, right — in fact distribution theory : representing a function by convolving against approximations to the identity with a kernel that converges to the Dirac delta function is a well known and beautiful way to densely approximate any integrable function — a much vaster set of functions, which includes wildly non-differentiable and even discontinuous functions — by infinitely differentiable functions.

If the second time-derivative is going to zero, one would be approaching a steady state of no change, i.e. no new energy entering or leaving the system.

The second time-derivative of what, prices of Apple stock, immigrant flows through Ellis Island ?  That is only the case when we’re talking about position (potential energy mass * dx).   

If the second time-derivative is positive, why would that induce flickering? If the second derivative is positive at a point, are not you not only providing half the story? Wouldn’t you need to see how the change is changing over time rather than tending? 

Yes exactly, that’s why I speak of second time-derivative f’’: change is f’  and change of change is f’’.

If the potential is locally a quadratic with nonzero second derivative, then it looks like a parabola (in potential space).   The classic dynamic (solution) subject to that sort of potential (differential equation) is harmonic oscillation. 


For the thing to flicker, one would need discontinuities in the system or very tight oscillations to the changing system... tending-positive to infinity, finding another “plateau” of zero (or near zero) and then another tending-negative to infinity and repeat
This flickering effect feels like a cycling of meta-stability where contributing factors within the system impede the system from acquiring a one way or the other... or exit that meta-stable state... the correlation lengths would depend on the energy dynamics of the system, how rough the cycling is, i.e. how much energy is required to get out of the troughs of the meta-stability yet not enough to break away from the cycling and revert to the meta-stable trough. Experimentally, to break the spell one needs to introduce ever larger amounts of energy, heighten the amplitude of the energy dynamics as roughness into the cycling so one overwhelms the threshold boundary and break free from the prevalent dynamic onto another regime. You gotta introduce some rough stuff into the system, i.e. introduce difference or change, to mix it up and break free from the toxic stability....

Does this make sense?

Not clear what you mean by all this.  Are we speaking of the base space, or the state space of configurations, or the space of potential energy (functional on configurations)?

I hope this doesn’t land like a hair in the soup, like they say in Qc French.

hahaha , what’s that in quebecois?

Best, Felix

Thanks.  Can we talk with Pavan, and then Steve Heims?

Yes I’d be very interested in such collective movement experiments.  But then it is urgent that we really prep our own measurement methods and team (Garrett?, ___ ? assisted by Julian).

As you know, I would want to measure correlations not (only) in the brain but across much more of the event.   
It is far more direct (scientifically rigorous) to measure as much of the global aspects of collective movement than to zero in on only one part of the body and in fact a part whose functions are extremely indirectly related to corporal kinetics, and in ways that are quite ill understood . 

That’s why I’ve asked Julian and our students to build out the rhythm kit to use all modalities of sensing intervallic rhythm.


in particular: 


and as an aside:

Can we talk with Pavan, and then with Steve?

Thanks,
Xin Wei

Subject: Back to music and brain

Hey Todd,

Hope you’re good.

I have been working and thinking about a couple of issues a lot lately in group neuroscience .. the two key topics are joint action and entrainment.   Joint action is just multiple actors working together to accomplish some task … like two people carrying a table together, or a couple of soccer players moving the ball down the field.   These are interesting problems because they require the actors to have some sense of what their partners are trying to accomplish and how they are going about that.   Entrainment is an entirely hypothesized process in which two brains come into “synchrony” in order to communicate .. this is thought to be important in language, but obviously is also important in music performance.

Entrainment, however, is pretty loosely defined at the moment … we have an idea for getting at entrainment using musicians.    The notion is to get an ensemble together, a good ensemble … and record simultaneous EEGs from the players as they work a piece.

To some extent this has been done before:   with saxophones (ugh!)   The focus of that paper was on EEG markers of empathy (even more ugh), and the usual expected changes in EEG associated with listening to and motor outputs for music.

What I’d like to do is do real analysis across multiple brains during performance, and see if we can see electrical signs of entrainment as they are working.   In a dream world, as the ensemble locks into “togetherness” … the brains will entrain.   Or vice versa.  

Anyway, to go after this we will need to synch up multiple EEGs, and more importantly, find a good ensemble that might be up for this.    

I thought of AME, and wondered if there would be somebody there interested in devoting a little bit of time and nominal resources to chasing this down.

In any case, have good holidays,

STeve

Hardcastle and Stewart succinctly point out a fundamental problem at the heart of the methodology of neuroscience (and of cognitive science): the modularity thesis.

Neuroscience did not “discover” modules — loci of functions —  in brains.   Rather “they don’t even have a good way of accessing the appropriate evidence. It is a bias in neuroscience to localize and modularize brain functions.”

The problem with scientistic methodology is that you see what you expect to see.



There’s much more in play: Noah Brender’s work questions the modularity thesis underlying much of technoscience. 
However, another world is possible :)

Thanks for being on the demo team !  Now we can get back to steady state  work, like rhythmanalysis 
textures.posthaven.com/
rhythmanalysis.weebly.com

Can you please check out the IMU’s that we bought last year as an input for our rhythm test platform?
Ask Ozzie or perhaps one of Prof. Turaga’s students who’s used them for permission and see if you can stream them into Max.

I’d like assemble a suite of inputs:
contact mic
air mic
camera (Julian)
IMU (Pavan’s group?)
xOSC gyros (Mike —> Julian)

and record them in parallel
with some movement scenarios to get multiple streams of time data.

Please define some scenarios : e.g.  assembling blocks small to giant size, cutting and washing .  try seated and upper body and locomotive.   Varsha’s done some movement scenarios with Grisha, but in very specialzied contexts.  How about quotidian ?

Let’s try some out on Monday Nov 30?

Cheers,
Xin Wei

Here’s a journal article published by a couple of researchers hosted at Synthesis last year that may be interesting to folks working on movement and responsive media, somatic experience, experimental dance and experimental technology, critical studies of technoscience, or philosophy of movement:

Teoma Naccarato, John MacCallum, “From Representation to Relationality: Bodies, Biosensors, and Mediated Environments,”  in Embodiment, Interactivity and Digital Performance, Journal of Dance and Somatic Practices, 8.1, 2015.

Teoma is starting a PhD with the Centre for Dance Research (C-DaRE), Coventry University UK
and John is a postdoc at the Centre for New Music and Audio Technologies (CNMAT) Department of Music, University of California at Berkeley. 

John and Teoma’s extended journal article is a good example of a durable outcome from the research cluster hosted by Synthesis in the Heartbeat Residency: Choreography and Composition of Internal Time.  This was a residency on temporality — sense of dynamic, change, rhythm — held February 15- 20, 2015. AME iStage, Matthews Center, ASU.




Ambient color changes according to whether dancer’s heart is faster or slower than some rate in the rhythm accompaniment software.  Synthesis Residency Jan 2015.   (The overhead tube lamps from Ziegler’s “forest2" were not used in this particular experiment.)

While FTM is somewhat discontinued, this all is being moved to IRCAM's free Mubu package:
http://forumnet.ircam.fr/product/mubu/
download the package and quickly check some of their example patches.

poster: 


It contains optimized algorithms building on gf, FTM, cataRT, pipo, etc. While mubu is audio-centric, it is not necessarily audio-specific. mubu buffers can work with multiple data modalities and use a variety of correlation methods to move between these layers... This makes up a fairly wholesome platform without the need to move back and forth between gf, FTM, concatenative synthesis instruments, multimodal data handling, analysis, and etc.

As with most current IRCAM releases, it is highly under-documented. Besides gf that is distributed with their package, the mubu.hhmm object might be good place to start for what you are looking for:


also their xmm object might be of interest:

It’d be great if you can give the Signal Processing group some Real Live Data to matlab offline this week, as a warmup to Teoma + John’s data the week of Feb 15.

We must have video journaled as well, always.

I’d be interested in seeing an informal brownbag talk about Lyapunov exponents one of those mornings of the week of Feb 15, together with some analysis of the data. 

Let’s cc Adrian Freed and John MacCallum on this “gyro" thread —
Adrian’s got the most insight into this  and could help us make some actual scientific headway
toward publishable results.

My question is : By doing some stats on clouds of orientation measurements
can we get some measure of collective intention (coordinated attention)
not necessarily at any one instant of time (a meaningless notion in a relativistic world like ours) — 
but in some generalized (collective) specious present?

Let’s plan John and Teoma’s workshop hour by hour schedule this coming week at a tea?

Kristi or Garrett, or __: please let us know when the “heartbeat”  workshop weebly site is posted and linked to the Synthesis research ok?

  Tt would indeed to at least develop a road map for this important work. We should bring the folk from x-io

  They are still unfortnuately in pre-order land with a 2-3 month shipping time. Such a system would complement commercial and inertial measuring systems well

  For the meeting we should prepare to share something about our favored use scenarios.

 Hello!
  Yes, there is great demand for something that works in sensor fusion for inertial sensors but I think the best way to do so is as part of o. so to benefit every inertial setup out there. It will take ages for Seb to implement it for xosc and would be an exclusive benefit. Seb's PhD is out there and I am sure he will help sharing new code for solving the problem. The question is can we do this? :)
  My warm regards to everyone!

  Are you using their IMU (x-OSC) as a source of inertial data?
 
  We started to integrate Seb's code into Max/MSP but concluded it would be better to wait for Seb

Not only handcraft manufacture, not only artistic and poetical bringing into appearance and concrete imagery, is a bringing-forth, poiesis. Physis also, the arising of something from out of itself, is a bringing-forth, poiesis. Physis is indeed poiesis in the highest sense. For what presences by means of physis has the bursting open belonging to bringing-forth, e.g., the bursting of a blossom into bloom, in itself (en heautoi). In contrast, what is brought forth by the artisan or the artist, e.g. the silver chalice, has the bursting open belonging to bringing­ forth not in itself, but in another (en alloi), in the craftsman or artist.
