High fidelity three‐dimensional (3‐D) numerical simulations of commercial‐scale coal gasifiers are very time consuming and expensive. This article proposes a reduced‐order modeling approach that uses quasi one‐dimensional (1‐D) CFD–DEM simulation results to serve as an accurate initial condition for the 3‐D simulation, which significantly shortens the physical time from several hours to minutes to...
Nonorthogonal multiple access (NOMA) transmission is a popular candidate technology for the next generation broadband mobile communication systems because of high spectrum efficiency. In this paper, we proposed two beamforming scheme, namely, matched-to-the-stronger-channel (MSC) beamforming and optimal beamforming schemes for a two-user downlink NOMA system. Moreover, we also develop optimal power...
A multi-faceted graph defines several facets on a set of nodes. Each facet is a set of edges that represent the relationships between the nodes in a specific context. Mining multi-faceted graphs have several applications, including finding fraudster rings that launch advertising traffic fraud attacks, tracking IP addresses of botnets over time, analyzing interactions on social networks and co-authorship...
This paper presents a new land use suitability classification (LSC) method on the basis of Ant Colony Optimisation (ACO), which is one kind of AI techniques. ACO algorithm can be used to discover suitability classification rules according to training cases. Classification rules and training cases are all organised in the form of IF-THEN, which generally incorporates practical human knowledge. To implement...
