In the context of discontinuous Galerkin spectral element methods (DGSEM), τ -estimation has been successfully used for p-adaptation algorithms. This method estimates the truncation error of representations with different polynomial orders using the solution on a reference mesh of relatively high order.
An algorithm to estimate the direction of arrival (DOA) in non uniform linear antenna arrays based on the use of Mercer’s kernel nonlinear interpolation is introduced. Interpolation is followed by the synthesis of a virtual uniform array.
A Ground Control Station (GCS) is an essential element to supervise and control autonomous vehicles performing complex missions in real time. In the new era of Internet of Things, where systems are highly connected, these missions demand enormous amounts of computational power to correctly manage the coordination of all the vehicles involved.
Turbine blades operating in transonic-supersonic regime develop a complex shock wave system at the trailing edge, a phenomenon that leads to unfavorable pressure perturbations downstream and can interact with other turbine stages.
This paper describes how the global stability of a circular cylinder is affected when submerged in a two-phase gravitational flow. The flow behavior is governed by both the Reynolds and the Froude number, while the depth of the cylinder has been varied to create different scenarios for the stability analysis.
