In this letter, we first propose an image restoration model with dyadic bounded mean oscillating (BMO) constraints to recover some clear texture from noisy data. The existence and uniqueness of the solution are discussed. The model is transformed into wavelet domain and then solved by dual Uzawa method. Each Lagrange multiplier of the discretized model corresponds to a certain scale of dyadic region...
Benefiting from the virtualization technology, virtual cluster system possesses a lot of advantages different from traditional cluster system. However, the availability analysis of virtual cluster system is still short of efficient methods. The availability analysis of virtual cluster node is the base of analyzing the availability of virtual cluster system. In this paper, we summarize a typical architecture...
Based on Reynolds-averaged Navier-Stokes equations, the three-dimension solid model, three-dimension model without supporting frame and two-dimension model of orifice rotameter were computed using computational fluid dynamics (CFD) method. The numerical computational results and experiment data were compared and analyzed in detail. It can be learned from analysis that the full-scale error of two-dimension...
In civil engineering curriculum, coursework tends to focus on the theoretical fundamentals or manual calculation. As a result, students have difficulty to adapt requirements for huge and complicated computation in real design projects. A 32-lessons of structural computation (SC) using ANSYS has been developed. This paper describes goals for teaching SC in civil engineering. The methodology and infrastructure...
