Warning! The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased. in plants. There are two distinct primary forms of branching, dichotomy and monopodial branching. False dichotomy arises from monopodial branching: the growth of the main axis stops and two nearly identical second-order branches, opposite each other, develop below its top and grow beyond the main axis. Figure 1. In addition to the stems, the roots, inflorescences, veins (conducting bundles) in leaves and stems, thalli in lower plants, and so forth can also branch. Basic Chaos and Fractals Intro. Simple Iterative Fractals The geometry of Fractals lies somewhere between dimensions.
To be totally accurate "fractal" is even not a 'thing' at all but more like a unit of measure or mathematical characteristic. For example each fractal has a 'fractal dimension' which is it's degree of regularity and repetition. CANTOR SET: One very simple way to understand fractals and the meaning of "iteration" is to examine a simple recursive operation that produces a fractal pattern known as Cantor Set. you take a line of arbitrary length and remove the middle third. this is the first step or "Iteration", then take the remaining two lines and repeat the clipping procedure. Eventually after 5 or 10 iterations you have dozens of tiny lines which take up only as much room as the two original ones from the first step. From Wikipedia "The Cantor set, introduced by German mathematician Georg Cantor, is a remarkable construction involving only the real numbers between zero and one. Algorithmic Botany: Publications.
Jose's sketchbook - A personal collection of ideas, programming and shiny stuff. In the field of Texture Synthesis, I recently discovered the wonders of the Reaction Diffusion System for nature-like patterns synthesis.
The RD method consists on a set of equations which iteratively simulate the distribution of a chemical agent (activator) modulated by the presence of another agent called inhibitor. It is believed that such interactions take place in nature to form patterns which can be found in mammals and fish, and the first model, generating spots, was proposed by Turing himself [Turing 52], dating back from 1952!.
Reaction Diffusion By playing with the parameters of an RD system, it is possible to simulate a variety of patterns ranging from spots to stripes. Unfortunately I haven’t found huge amounts of information on the subject (let alone up-to-date resources): one of the most complete texts is Greg Turk’s thesis [Turk 91], which covers both Turing-like spots and stripes. RD Strip system as appears in |Asai 99|. 'Space' key to reset simulation. References. May 2010.
Thursday, May 27, 2010 Existence of RNA 'dark matter' in doubt : Nature News "The abundance of transcripts from the genome may have been overestimated.
RNA 'dark matter' hinted at by previous studies of mammalian genomes may not exist after all. The mysterious matter refers to the large amounts of RNA that are copied from the DNA sequence, or transcribed, but which cannot be accounted for by the genes that have been identified so far.

Wednesday, May 19, 2010 C Library for Simulated Evolution of Biological Networks ". Molecular robots. Mathematical biology. Motivation. Firstly, I should probably answer the question of what mathematical biology actually is.
As the name suggests, it is the application of mathematical techniques to biological problems. But why should we want to do such as thing, when experiments can be run? Why would be want to turn the beauty of nature into an ugly equation? Well, here are a few reasons off the top of my head: Experiments can identify cause and effect relationships. As mentioned above, my main interest is in pattern formation. An important aspect of Turing's is that it suggests many types of animals depend on the exact same mechanism to produce their individual patterns. The patterning systems we use tend to rely on diffusion as the key mechanism. Next week I'll be demonstrating how we model diffusion mathematically.

The condition of the interior space in terms of lighting and thermal comfort was of primal concern during this phase of the design. These conditions can be controlled in the interior through the generated skin. Interior formal elements were chosen from the AnaHYBIOS models to be introduced as final geometry generators.
The final geometry in this case being composed of spatial instances where the instance is shaped by the effect of force on matter to produce an environmentally controlled space. A space that is affected by the exterior weather conditions in a specific location. Limitations of the material system were considered while the conditions are set for the mesh relaxation algorithm to produce desirable spatial outcomes. One major limitation of the HYBIOS system is the amount of vertical distance needed to achieve a habitable floor area.

Scenario: 1) Recognition of the “natural” fake of the place (polder developed on the lake) 2) Development of a strategy heterotopic, tentacular, uncertain, organic. 3) Scenarios of confusion between various natures - built natures (facade in hydro-aeroponiques, biodynamic green hairs) and urban, spontaneous, haunted natures, in order to generate a hybrid landscape, non-identifiable. 4) Using the photosynthesis of all green façades to recycle and clean waste water. 5) Introduction of this knotty geometry into indoor morphology of the exhibition rooms. 6) Individual positioning by portable GPS, coupled to an informational PAD.
