As a solution for the overhead caused by the HWMP control messages, DCRP explores the structure provided by the cluster layer to allow query localization and the local repair of the HWMP.
Figure5 shows an STM image of Ge islands (dGe = 0.3 nm) on Ge0.3Si0.7 (dGeSi = 10 nm)/Ge hut-cluster layers (dGe = 0.6 nm) at 500°C.
Conversely, in the hierarchical approaches, the network is divided into geographically clustered layers by using some clustering technique, and according to specific requirements or metrics, such as the energy reserves and proximity of sensor nodes (Singh et al. 2010; Pantazis et al. 2013; Jain and Gupta 2015).
Zhao et al. [4] presented the three-layer framework for mobile data collection in wireless sensor networks, which includes the sensor layer, cluster head layer, and mobile collector layer.
Clustered, layered and stacked — these earrings, rings and bracelets glitter most brightly in groups.
This paper presents a density peak based hierarchical clustering method (DenPEHC), which directly generates clusters on each possible clustering layer, and introduces a grid granulation framework to enable DenPEHC to cluster large-scale and high-dimensional (LSHD) datasets.
In contrast with the usual assumption, the product size seems driven not by inter-particle contacts in airborne state but the ability of the solids to gain kinetic energy and break up a collection of clusters layering on the wall.
This selective output signaling mechanism allows the signal generated in a node in the input layer to be transmitted to a node in the clustering layer only when the signal is similar to the top-down weight between the two nodes and, hence, PART focuses on dimensions where information can be found.
When the Si wafer was dipped into the etching solution, a silver nano-cluster layer was formed on its surface.
In practice, it is difficult to decide the number of clusters or layers of clusters needed, and the samples often show genuinely graduated differences of expression patterns.
