A hybrid numerical model for simulating atmospheric contaminant dispersion is developed. The hybrid numerical scheme employs an hp-adaptive finite element method coupled with a Lagrangian particle transport technique to solve the governing equations for atmospheric flow and species transport. A random walk/stochastic approach is used to generate Lagrangian particles that define the contaminant ...

Results are presented for a new code designed to perform high-order direct numerical simulations of high-speed flows over arbitrary geometries. The simulations were performed on a Cartesian grid with the geometries imposed by a third-order cut-cell method. A multizone refinement method is also implemented to provide extra resolution at locations with expected complex physics. The simulations al...

This paper presents a theoretical framework for the integration of the cooperative constraint solving of several algebraic domains into higher-order functional and logic programming on λ-abstractions, using the instance CFLP(C) of the generic Constraint Functional Logic Programming (CFLP ) scheme [7] over a so-called higher-order coordination domain C. We provide this framework as a powerful co...

Future wireless Am networks are expected to support a variety of services with different bit-rates and Quality-of-Service (QoS) requirements. A major challenge for these networks is the de= sign of the multiple access scheme. In our previous works, we proposed hybrid CDMA/TDMA technique as an appropriate multiple access control (MAC) scheme for wireless Am networks. We also investigated the pro...

Community detection is a research hotspot in machine learning and data mining. However, most of the existing community methods only rely on lower-order connectivity patterns, while ignoring higher-order unable to capture building blocks complex network. In recent years, some based structures have been developed, but they mainly focus motif network composed structures, which violate original top...

The hybrid signcryption scheme based on certificateless public key cryptography avoids the complexity of certificate management existing in the traditional public key cryptography and the inherent key escrow problem existing in identity-based public key cryptography. The certificateless hybrid signcryption scheme combined with certificateless signcryption key encapsulation mechanism and data en...

In this paper, an improved seventh-order WENO (WENO-Z7) scheme is suggested by extending the 5th-order WENO scheme of Borges et al[R. Borges, M. Carmona, B. Costa, W. S. Don, An improved weighted essentially non-oscillatory scheme for hyperbolic conservation laws, J. Comput. Phys. 227(2008) 3191-3211]. The sufficient condition for seventh-order accuracy is described for the new smoothness indic...
