Melody Swartz

Swiss Federal Institute Of Technology, Lausanne (Switzerland) Cell Migration and Pattern Formation Guided by Dynamic Microenvironments http://www.subtletechnologies.com/symposium/Swartz.html

  • env. dynamics -cellular [feedback loop / response)
  • cellular microenvironments → tissues
  • env. cues → structures * sensing gradients - movement/ sensing * gradients drive morphogenesis * esp. extracellualr matrix * chemotatic agent → cell migration lymphatic system → faciliate interstitial flow
  • flow nec. for coupling organisation cells respond to gradients [always under flow]
  • cells can create their own gradietns thru releasing precursors
  • hence self-regulation autocrine transcellular migration autochemokine → autochemotactic (ref.)

Michelle Addington

Harvard University (US) Smart Materials http://www.subtletechnologies.com/symposium/Addington.html Michelle Addington and Daniel Schodek, “Smart Materials and Technologies for the Architecture and Design Professions.â€

  • architecture - inside boundary layers
  • architectural imperatives for smart materials
  • impossible 'magical' materials, solving all existing problems
  • pragmatic embedding within the existing uses of materials
  • normative categorisation
  • materials → artifacts/ didactic
  • current architectural use denies behaviour, often ignoring dynamics

energy tansfer (proportial to) material propertiy x change of state cf hooke's law, fourier's law aerogel → linear

indep. vars. dep. vars
1. state material property (eg. … )
2. energy quantity material property (eg. thermochromic)
3. energy quantity energy type (eg. electrochromic)
4. energy quantity multiple states (eg. SMA)

requisite descriptions

state change  property change
            X
energy input  energy output
  • what can be done with materials using their particular characteristics, rather than thrying to solve tradition problems.
  • escape Eulerian surface → Lagrangian
  • need to be more aware of operative scale, eg. sound (macro) → light diffusion (pico)
  • potential for large changes by working at a scale appropriate to the material and properties (eg. peltier / healt/light/microns)
  • problems with desinging subordinate to technology & demands of current tech.
  • fluroescent lighting (ref. GE 1936)
  • genesis of whiteness in interior design
  • problems with lumioence, and spread
  • ideal of a homogenous lighting field

IESNA → 'ideal' lighting level recomendations

1910 ~ 10lux
1950 ~ 300lux
1981 ~ 2000lux
2000 ~ 400-3000lux
  • visual system
  • entire human visual system is active at ~3lux
  • neural sys. for sight activated by gradients, luminecence not nec. important
  • rifts in luminance
  • LEDs → dealing with light directly,
  • scripting rifts in perception of luminance
  • most arch.projects dont focus on unique properties of LEDs, impose older ideas of lighting. eg. LEDs to replace fluro tubes
  • architecture to induce phenomelogical behaviours. physiology → perception
  • architectural suggestions
  • generalised principles, with unique and local strategies
  • decoupled, rather than integrated technology
  • supra, rather than subordinate role to tech
  • leveraging tiny phenomena to produce significant behaviours
  • boundary layer
  • boundary layer as zone of interaction, and active adaptation
  • all exchnage of energy in buildings occurs at the boundry layers
  • boundary layers are active gradients
  • away from artifacts & orthographic projections
  • perspective and depth → luminance cues
  • shape → colour cues
  • “art and …” Margret Livingstone (ref. visual perception in art)

  • material systems
  • parameteriation of components → modular construction
  • hybGrid
  • physical system for producing flexible structures from micro components. freestanding
  • planned → hybrid physical/digital to transfer digital models to parameterisable units.
  • local config → global structure

Donald E Ingber

Harvard University (US) The Architecture of Life

  • physical forces → cell development
  • cells as tensegrity structures (cf. cytoskeleton & internal strucutre)
  • nature builds structures using heirarchy of layers of structural integrity
  • eg. cytoskeleton (microfilaments → intermediate filaments → micro tublules)
  • cells stick to ECM (extra cellular membrane) at focal(?) points
  • tension in microfillalments is balanced by local regions of the substrate (ECM) which resist being compressed
  • cell shape is stabilised thru the balance of mechanical forces
  • cell & nucleus are connected in the tensegrity model (ref. various cellular & intracellular structures as tensegrity strucutres, virii, red blood cells, etc+ - sciAm article?)
  • tensegrity based heirarchical integration of cellular structures
  • solid state biochemistry on cytoskeleton (mechanical catalysts)
  • focal adhesion point → electro-mechano-biochemical mechanism
  • physical microenviroment governs tissue pattern development
  • dynamic reciprocity

  • complexity cf. warren weaver (ref)
  • simplicity → disorganised complexity → organised omplexity
  • FEM (fininte element method) * Arghris, J (ref. argyris?)
  • combining analysis and generation
  • materials to distribute load, similar to a FE mesh
  • cellular → space frame
  • topology - connections between nodes → genetic algorithms
  • geometry - position of nodes → learning algorithms
  • evolution of modular unit cubes
  • first - evolve optimial topology
  • then - optimize geometry & learn which spatial arangements 'work'
  • machine learning - neural model based on McCulloch? & Pitts
  • evolving structures to undergo dynamic forces (ie. +ve poisson's ratio)
  • axial line analytics → nn
  • cities as CAS
  • unit based simulations scale linearly, rather than exponentially
