  • This study first examined the social meanings of typicality found in the prison, (solitary) confinement, and conduit(passage) in Peter Halley's works, in which both the prison and (solitary) confinement represent a suppressed structural framework. The former has freedom and escape excluded from it, and the latter allows for mutual regulation and connection as a space of positive mediation. Conduits are interpreted to be flexible and have the potential of creating something new through connection and communication with the outside world. The study then compared and analyzed the meanings of typicality in Halley's works and the concept of segments proposed by Gilles Deleuze and Félix Guattari as social justice in that both of them were in the same context. The findings lead to a conclusion that Halley's prison, (solitary) confinement, and conduit(passage) can be connected to a solid, flexible, and escape segment, respectively, by Deleuze and Guattari.

  • A dynamic Monte Carlo percolation grid simulation is used to predict the cure behaviour of thermoset materials. Molecules are distributed in a fixed grid and a probability of reaction is assigned to each pair of neighbouring units considering both reaction rates and diffusion. The concentration and network characteristics are predicted throughout the whole curing process and compared to experimental data for an epoxy-amine matrix.

  • This paper describes an extension of viscoelastic Group Interaction Modelling (GIM) to predict the relaxation response of linear, branched and cross-linked structures. This model is incorporated into a Monte Carlo percolation grid simulation used to generate the topological structure during the isothermal cure of a gel, so enabling the chemorheological response to be predicted at any point during the cure. The model results are compared to experimental data for an epoxy-amine systems and good agreement is observed. The viscoelastic model predicts the same exponent power-law behaviour of the loss and storage moduli as a function of frequency and predicts the cross-over in the loss tangent at the percolation condition for gelation. The model also predicts the peak in the loss tangent which occurs when the glass transition temperature surpasses the isothermal cure temperature and the system vitrifies.
