The proper management of the signal to noise ratio margin is important for improving the stability of digital subscriber line (DSL) networks and increasing the customer satisfaction regarding services such as triple-play. This work presents a novel algorithm for multiuser margin optimization that benefits from the relationships between power and margin adaptation. The proposed multiuser margin maximization...
In the field of computer graphics, physically-based fluids simulations (i.e., simulations that solve the equations that govern fluids behaviour) are performed using, among others, Stam's stable fluids method. This method requires the solution of two sparse linear systems that can be solved using an iterative solver (e.g., Jacobi, Gauss-Seidel, conjugate gradient, etc.). Focusing on real-time 3D applications,...
This work presents the analysis of the tapered microstrip patch antenna by the Wave Concept Iterative Procedure, WCIP. The resonant frequencies variation with the patch dimensions and how to include it as project flexibility is discussed. The behavior of the electric fields is presented and analyzed for the first two resonant frequencies. Numerical and measured results are compared and a good agreement...
This work presents the analysis of quasi-square open ring frequency selective surface, FSS, using the Wave Concept Iterative Procedure, WCIP. As this structure presents a strongly dependence of the electric field polarization, different frequency bands can be selected. Furthermore, there is a coupled strips region and its length can be used for frequency adjustment. The behavior of the electric fields...
