A hybrid transmission scheme for networked control systems.

Due to its obvious advantage on the efficient use of resources, the event-triggered mechanism is quickly applied in networked control systems (NCSs). However, when some event-triggered data packets are lost during network transmissions, it will become very challenging to analyse the NCSs since two consecutively event-triggered data are internally correlated and the relation will be destroyed when one of the data get lost. With the consideration, this paper proposes a hybrid communication mechanism for NCSs with data loss.

The Stability Analysis Method of the Cohesive Granular Slope on the Basis of Graph Theory.

This paper attempted to provide a method to calculate progressive failure of the cohesivefrictional granular geomaterial and the spatial distribution of the stability of the cohesive granular slope. The methodology can be divided into two parts: the characterization method of macro-contact and the analysis of the slope stability. Based on the graph theory, the vertexes, the edges and the edge sequences are abstracted out to characterize the voids, the particle contact and the macro-contact, respectively, bridging the gap between the mesoscopic and macro scales of granular materials.

The Quantified Characterization Method of the Micro-Macro Contacts of Three-Dimensional Granular Materials on the Basis of Graph Theory.

We have attempted a multiscale and quantified characterization method of the contact in three-dimensional granular material made of spherical particles, particularly in cemented granular material. Particle contact is defined as a type of surface contact with voids in its surroundings, rather than a point contact. Macro contact is a particle contact set satisfying the restrictive condition of a two-dimensional manifold with a boundary.
