The fault diagnosis approach based on signed digraph is promising, but signed digraph models built by existing methods often contain false causalities and make spurious diagnosis results. In this article, a signed digraph modelling method based on causal dependence identification is proposed. Many equations used to describe mechanism of process system can be used to analyse the cause–effect r…
A series of low-molecular-mass organogelators (LMOGs), dimeric dendrons based on natural amino acids, glycine. and aspartic acid, with different aliphatic spacers have been synthesized and their selfassembly behavior and structure-property relationship have been studied. Transmission electron microscopy (TEM), atomic force microscopy (AFM), infrared spectroscopy (IR), and small-angle X-ray s…
