    Turing Patterns in a Predator-Prey System with Self-Diffusion by Hongwei Yin, Xiaoyong Xiao, Xiaoqing Wen

    Published 2013-01-01
    “…However, in the real world, the tendency for prey and predators moving along the direction of lower density of their own species, called self-diffusion, should be considered. For this, we investigate Turing instability for a predator-prey system with nonlinear diffusion terms including the normal diffusion, cross-diffusion, and self-diffusion. …”

    Pattern Formation in a Cross-Diffusive Holling-Tanner Model by Weiming Wang, Zhengguang Guo, R. K. Upadhyay, Yezhi Lin

    Published 2012-01-01
    “…Furthermore, we present novel numerical evidence of time evolution of patterns controlled by self- as well as cross-diffusion in the model, and find that the model dynamics exhibits a cross-diffusion controlled formation growth not only to spots, but also to strips, holes, and stripes-spots replication. …”

    La diffusion spatiale de l’informatique en Inde by Divya Leducq

    Published 2009-09-01
    “…Beyond the fact that InfoTech are seen as a trickle-down development engine, it is the cluster which has become gradually a town planning measure in the sectoral policies followed by the central government and the regional states. The diffusion of this spatial model can be explained by the success stories which made the reputation of India and the expected benefits in terms of innovation. …”

    Evaluation of effective diffusivity correlations for soybeans in thin layer drying by Felipe d'Avila, Rafael Maurício Urnau, Amanda Mansano Zanella Blauth, Marcos Flávio Pinto Moreira

    Published 2020-10-01
    “…The correlation proposed by Dotto et al. (2018) was the one with the lowest average error (0.048%) for the consideration of an average effective diffusivity. In order to consider a punctual effective diffusivity, modifications were made to the Dotto model, providing a maximum error of 2.6%. …”
