Single component pseudo-potential lattice Boltzmann models have been widely studied due to their simplicity and stability in multiphase simulations. While numerous model have been proposed, comparative analysis and advantages and disadvantages of different force schemes is often lacking. A pseudo-potential model to simulate large density ratios proposed by Kupershtokh et al. [1] is analyzed in ...

Abstract Recently, Guo and Nixon [1] proposed a feature selection method based on maximizing I(x; Y ), the multidimensional mutual information between feature vector x and class variable Y . Because computing I(x; Y ) can be difficult in practice, Guo and Nixon proposed an approximation of I(x; Y ) as the criterion for feature selection. We show that Guo and Nixon’s criterion originates from ap...

The fervor with which carbon initiatives are being adopted (Capoor & Ambrosi 2007) presents a unique opportunity to restore biodiversity while creating new financial and marketing incentives for investors. We argue that current approaches to carbon offsetting that rely largely on investment in monoculture plantations will rapidly lose appeal as the public becomes aware of their dubious carbon b...

We will present some recent work on phase-field models for twophase fluids with variable densities. The Quasi-Incompressible Navier-Stokes-Cahn-Hilliard model with the gravitational force being incorporated in the thermodynamically consistent framework will be investigated. Under a minor reformulation of the system we show that there is a continuous energy law underlying the system. For the ref...

GaN FETs offer superior advantages in high-voltage and high-temperature operation due to its large bandgap (3.4 eV) and high breakdown field strength (3.3 MV/cm). This combination of the large bandgap and high breakdown field makes these devices very attractive for power switching applications. In this regard, a key figure of merit is the breakdown voltage of the transistor, which must be high ...

The project uses Hong Kong as an testing example to figure out the possibilities of combine digital space with physical public spaces, thus further reinforcing the social interaction. As the society of Hong Kong now is tending to be digitalized, the existing physical public space, which was designed in the past can not reflect changing and digitalizing society anymore. This makes the physical p...
