Metaphysics of genetic architecture and computation

Karl Chu ruminates on the far-reaching impact that the convergence of computation and biogenetics will have on the unfolding history of man and nature. Could the world be ‘moving into the so-called Post-Human Era, which will bring forth a new kind of biomachinic mutation of organic and inorganic substances’? How can architects reconfigure the practice of their discipline in order to meet the demands of this computational and biogenetic revolution? Copyright © 2006 John Wiley & Sons, Ltd.     

Bifurcations of Propellant Burning Rate at Oscillatory Pressure

A new phenomenon, the disparity between pressure and propellant burning rate frequencies, has revealed in numerical studies of propellant burning rate response to oscillatory pressure. As is clear from the linear approximation, under small pressure amplitudes, h, pressure and propellant burning rate oscillations occur with equal period T (T‐solution). In the paper, however, it is shown that at a certain critical value of the parameter h the system in hand undergoes a bifurcation so that the T‐solution converts to oscillations with period 2T (2T‐solution). When the bifurcation parameter h increases, the subsequent behavior of the system becomes complicated. It is obtained a sequence of period doubling to 4T‐solution and 8T‐solution. Beyond a certain value of the bifurcation parameter h an apparently fully chaotic solution is found. These effects undoubtedly should be taken into account in studies of oscillatory processes in combustion chambers.     

Calculation of Detonation Velocity,Pressure, and Electric Sensitivity of Nitro Arenes Based on Quantum Chemistry

The DFT‐B3LYP method, with basis set 6‐31G*, is employed to optimize molecular geometries and electronic structures of thirty‐nine nitro arenes. The averaged molar volume (V) and theoretical density (ϱ) are estimated using the Monte‐Carlo method, based on 0.001 electrons/bohr³ density space and a self‐compiled program. The detonation velocity (D) and pressure (P) of the explosives are estimated by using the Kamlet–Jacbos equation on the basis of the theoretical density and heat of formation (Δ_fH), which is calculated using the PM3 method. The reliability of this theoretical method and results are tested by comparing the theoretical values of ϱ and D with the experimental or referenced values. The theoretical values of D and P are correlated with the experimental values of electric sensitivity (E_ES). It is found that, for the nitro arenes, there is a linear relationship between the square of detonation velocity (D²) or detonation pressure (P) and electric sensitivity (E_ES), which suggests that such a theoretical approach can be used to predict or judge the magnitude of E_ES, which is difficult to measure in the molecular design of energetic materials. In addition, we have discussed the influence of the substituted groups and the parameters of the electronic structure on density, detonation velocity, pressure, and electric sensitivity, and have shown that the substituted groups have the effect of activity or insensitivity, and that the influence of Q_‐NO2 and E_LUMO is important.

On the concept of concept.

This commentary is in two parts: 1) a short review of problems with representational theories of mind, and 2) a critique and diagnosis of what I claim are fundamental problems with Wittgensteinian notions of grammatical analysis. These problems turn on an incomplete characterization of normativity in Wittgenstein's (and others') work. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
