Shape formation via elastic instabilities
… is placed under a load, it will deform to a new shape. Typically, these shape changes are modest and predictable, but sometimes, when a critical load is reached, the object will undergo an elastic instability and adopt a dramatically different and more complicated shape. Traditionally, elastic …

Shape formation by self-disassembly in programmable matter systems
… and control algorithms which manage information transfer between neighboring modules. These algorithms ensure that messages are delivered reliably despite challenging conditions. They monitor the state of all communication links and are able to reroute messages around broken …

Modelling morphogenesis as an amorphous computation
… viewpoint for morphogenesis, the process of shape formation during embryological development. We model morphogenesis as a self-organizing, self-repairing amorphous computation and describe how we can program large-scale shape formation by giving local instructions to cell-like objects. Our …

Water-based digital design and fabrication : material, product, and architectural explorations in printing chitosan and its composites
… design tools display little integration between shape formation and materialization resulting in disassociation between shape and matter. Contrarily, in the natural world shape and matter are structured through growth and adaptation, resulting in highly tunable and hierarchically structured …

The role of expansin in leaf development: A molecular genetics and AFM approach
Leaf shape formation is a fascinating process involving the coordinated regulation of cell division and cell expansion, which ultimately relies on the control of cell wall expansion. Expansins comprise a large family of cell wall proteins which can non-enzymatically trigger the relaxation of the …

Subsurface Planetary Investigation Techniques and Their Role for Assessing Subsurface Planetary Composition
… our knowledge of the history of planetary formation but also can lead to information about its future. Whether the investigation is being conducted remotely using imagers, radars or physically using penetrometers or drills, a pre-existed knowledge of the mechanical and electrical properties …

Novel probabilistic and distributed algorithms for guidance, control, and nonlinear estimation of large-scale multi-agent systems
… are widely used for constructing a desired formation shape, exploring an area, surveillance, coverage, and other cooperative tasks. This dissertation introduces novel algorithms in the three main areas of shape formation, distributed estimation, and attitude control of large-scale …

Modelling of premixed laminar flame propagating in channels
… For upwards propagating flames, the convex shape of the flame imposed by the mode of ignition combined with buoyancy can suppress the thermal-diffusive effects; in contrast, the buoyancy alone cannot damp the thermal diffusive effects even for quite large Froud numbers in regard to the …
