A component-based approach is introduced for fast and flexible solution of parameter-dependent symmetric eigenproblems. Considering a generalized eigenproblem with symmetric stiffness and mass operators, we start by introducing a “σ-shifted” eigenproblem where the left hand side operator corresponds to an equilibrium between the stiffness operator and a weighted mass operator, with weight-param...

Since the inception of discontinuous Galerkin (DG)methods for elliptic problems, there has existed a question of whether DG methods can be made more computationally efficient than continuous Galerkin (CG) methods. Fewer degrees of freedom, approximation properties for elliptic problems together with the number of optimization techniques, such as static condensation, availablewithinCG frameworkm...

The FE2 method is a very flexible but computationally expensive tool for multiscale simulations. In conventional implementations, the microscopic displacements are iteratively solved within each macroscopic iteration loop, although strains imposed as boundary conditions at micro-scale only represent estimates. order to reduce number of iterations, present contribution presents monolithic scheme...

statement of problem: when a tooth is treated endodontically, there are several objectives, which must be met for the root canal therapy to be successful. one of those objectives is the complete obturation of the root canal system. purpose: the purpose of this study was to evaluate the apical sealability of the theramfil endodontic obturation technique and compared it with lateral condensation....

We study static magnetic susceptibility $\chi(T, \mu)$ in $SU(2)$ lattice gauge theory with $N_f = 2$ light flavours of dynamical fermions at finite chemical potential $\mu$. Using linear response we find that exhibits paramagnetic behavior both the high-temperature deconfined regime and low-temperature confining regime. Paramagnetic becomes stronger higher temperatures larger values potential....
