The structural system of prestressed concrete (PC) voided slab deck is intermediate between plate and girder. Therefore, the conventional design method is based on the assumption that the system is similar to the plate system or to the grid system. In this paper, the structural behavior of a continuous PC voided slab deck with three spans was analyzed by using the three dimensional solid finite...

We propose a first-principles based method for calculating the electronic structure and total energy of solids in an intermediate-valence configuration. The method takes into account correlation effects (d-f Coulomb interaction) and many-body renormalization of the effective hybridization parameter of the f system. As an example, the formation of a pressure-induced intermediate-valence state in...

We consider interpolation between keyframe hierarchies. We impose a set of weak constraints that allows smooth interpolation between two keyframe hierarchies in an animation or, more generally, allows the interpolation in an n parameter family of hierarchies. We use hierarchical triangulations obtained by the Rivara element bisection algorithm and impose a weak compatibility constraint on the s...

In this work, a recovery technique for the intermediate nite element family of the second type is proposed and analyzed on a second-order elliptic model problem. It is shown that when the pollution error is properly controlled, the convergent rate of the recovered gradient is of two orders higher than the optimal global rate on an interior sub-domain where rectangular meshes of regular type are...

Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...

HeT-A elements are non-long terminal repeat (non-LTR) retrotransposons found in head-to-tail arrays on Drosophila chromosome ends, where they form telomeres. We report that HeT-A promoter activity is located in the 3' end of the element, unlike the 5' location seen for other non-LTR retrotransposons. In HeT-A arrays the 3' sequence of one element directs transcription of its downstream neighbor...

The finite element implement of the generalized Lorenz gauged A formulation has been proposed for low-frequency modeling. However, the inverse of mass matrix of intermediate scalar in the finite element implement leads to additional computation cost and dense coefficient matrix. In this paper we propose to adopt a diagonal lumping mass matrix in the finite element discretization of the generali...
