  • Publication number: 20240126936
    Abstract: A multi-scale aggregation pattern analysis method for a complex traffic network is provided, which belongs to the field of the highway traffic network. Firstly, an adjacency matrix, a position attribute matrix, a distance weight matrix, a road grade matrix, and a time-phased traffic congestion degree matrix of a highway traffic network are calculated; secondly, a weight influence factor of the road network is incorporated based on a PageRank algorithm to determine order of critical nodes; finally, a two-dimensional decision diagram is drawn by two indicators: order of critical nodes and a shortest path distance. A new weighting matrix which accords with the actual situation of the road network is obtained by incorporating a position weight matrix, a distance weight matrix, a road grade weight matrix and a dynamic traffic congestion degree weight matrix based on a similarity matrix of the spectral clustering.

  • Publication number: 20240105812
    Abstract: A nitride-based semiconductor device includes a first nitride-based semiconductor layer, a second nitride-based semiconductor layer, a third nitride-based semiconductor layer, a passivation layer, a gate insulator layer, and a gate electrode. The first nitride-based semiconductor layer includes at least two doped barrier regions defining an aperture between the doped barrier regions. The second nitride-based semiconductor layer is disposed over first nitride-based semiconductor layer. The third nitride-based semiconductor layer is disposed on the second nitride-based semiconductor layer and has a bandgap higher than a bandgap of the second nitride-based semiconductor layer. The passivation layer is disposed over the third nitride-based semiconductor layer, in which a vertical projection of the passivation layer on the first nitride-based semiconductor layer is spaced apart from the aperture. The gate insulator layer is disposed over the third nitride-based semiconductor layer.
