Botanical Fabrication: A research project at the intersection of design, botany and horticulture
Get PDF‘Botanical Fabrication’ is an on-going research initiative which investigates how an understanding of botany and horticultural techniques can challenge the design process and lead to alternative sustainable manufacturing or ‘eco-facturing’ tools. This paper presents different phases of the project, from an initial research workshop (2012), to an exhibition-based experiment (Botanical Factory, 2013) and includes current work in progress (Solar Gourd, 2015) so as to articulate a critical analysis of the work to date. In a context where we urgently need to devise new principles to live, manufacture and consume within the ecological capacity of our finite planet, the paper argues for the development of a new framework for slow manufacturing with plant systems. From Darwin’s research into plant movements to our current understanding of plant physics and biomechanics, designers can begin to integrate botanical and horticultural knowledge to play with the environment of plant growth and envision production chains of a new type
Collet lock joint for space station truss
Get PDFA lock joint for a Space Station has a series of struts joined together in a predetermined configuration by node point fittings. The fittings have removeable inserts. The lock joint has an elongated housing connected at one end to a strut. A split-fingered collet is mounted within the housing to insure reciprocal movement. A handle on the housing is connected to the collet for moving the collet into the insert where the fingers of the collet expand to lock the joint to the fitting
Rigidity of Holomorphic Collet-Eckmann Repellers
No full text. We prove rigidity results for a class of non-uniformly hyperbolic holomorphic maps: If a holomorphic Collet-Eckmann map f is topologically conjugate to a holomorphic map g, then the conjugacy can be improved to be quasiconformal. If there is only one critical point in the repeller, then g is Collet-Eckmann, too. 1. Introduction Collet-Eckmann maps of the interval were introduced by P. Collet and J.-P. Eckmann as a large class of non-uniformly expanding maps for which a probability absolutely continuous invariant measure exists. A theory of rational Collet-Eckmann maps was originated in [P2] and continued in [P3], [GS] and [PR]; see [PR] for a more detailed historical account. This paper is a continuation of [PR]. We consider repellers for holomorphic maps, without assuming the maps extend to rational maps. Consider a compact set X in the Riemann sphere C , together with a holomorphic map f : U ! C with f(X) = X, where U is a neighbourhood of X. We call the pair (X; f) a holomorp..
Porosity Of Collet-Eckmann Julia Sets
No full text. We prove that the Julia set of a rational map of the Riemann sphere satisfying the Collet-Eckmann condition and having no parabolic periodic point is mean porous, if it is not the whole sphere. It follows that the Minkowski dimension of the Julia set is less than 2. 1. Introduction Let f : b C ! b C be a rational map. Then f is said to satisfy the Collet-Eckmann condition if there are constants C ? 0 and ? 1 such that (CE) j(f n ) 0 (f(c))j C n for all n and all critical points c 2 J(f) of f whose forward orbit does not meet another critical point (J(f) stands for the Julia set of f ). Here and in what follows derivatives and distances are always with respect to the spherical metric of b C ; unless stated otherwise. A set E ae b C is called mean porous if there are constants p 1 ! 1 and p 2 ? 0 such that for each z 2 E the following holds: There is an increasing sequence n j of integers and points z j with dist(z; z j ) 2 \Gamman j such that n j ! p 1 j and dist(z j ; E) ? ..
Synchronization and Spin-Flop Transitions for a Mean-Field XY Model in Random Field
Get PDFWe characterize the phase space for the infinite volume limit of a ferromagnetic mean-field XY model in a random field pointing in one direction with two symmetric values. We determine the stationary solutions and detect possible phase transitions in the interaction strength for fixed random field intensity. We show that at low temperature magnetic ordering appears perpendicularly to the field. The latter situation corresponds to a spin-flop transition
