摘要:We introduce a preconditioner based on a hierarchical low-rank compression scheme of Schur complements. The construction is inspired by standard nested dissection, and relies on the assumption that the Schur complements can be approximated, to high precision, by Hierarchically-Se...

摘要:Abstract(#br)We previously introduced a preconditioner that has proven effective for h p -FEM discretizations of various challenging elliptic and hyperbolic problems. The construction is inspired by standard nested dissection, and relies on the assumption that the Schur complemen...

摘要:Abstract(#br)Cardiorenal syndrome (CRS) is defined as an interaction of cardiac disease with renal dysfunction that leads to diuretic resistance and renal function worsening, mainly with heart failure (HF) exacerbation.(#br)Hemodynamic variables linking heart and kidney are ...

摘要:This paper describes factors which have modified the original equilibrium of the Venetian Lagoon ecosystem. Human intervention started in 1400 AD. During the last two centuries man's activity upset the hydraulic and physical-biological balance of the lagoon by digging canals...

摘要:Abstract(#br)The paper reviews the construction of hierarchical H 1 -conforming shape functions for 1D (edge), 2D (triangle, quad) and 3D (hexahedron, tetrahedron, prism, pyramid) elements. The logic of implementation is based on identifying a set of core (kernel, bubble) 1D and ...

摘要:Abstract(#br)The paper proposes a new G 1 -interpolation and geometry reconstruction scheme for regular surfaces approximated with unstructured quadrilateral grids. The parametrization is based on C 1 transfinite interpolation and sixth order polynomials. The G 1 -conforming...

摘要:Abstract(#br)We focus on the development of a reliable numerical model for investigating the bone-conduction of sound in the human head. The main challenge of the problem is the lack of fundamental knowledge regarding the transmission of acoustic energy through non-airborne pathw...

摘要:Abstract(#br)Expressed sequence tags (ESTs) are providing a valuable approach to sampling organism-expressed genomes, especially when studying large genomes such as those of many plants. We report on the comparison of 8,647 ESTs generated from six different grape ( Vitis vin...
