Brick and Mortar Chip Fabrication Martha Allen Kim Chair of the Supervisory Committee: Professor Mark Oskin Computer Science and Engineering While Moore’s Law has advanced the semiconductor and technology industries, it has simultaneously driven up the cost of engineering a chip in a modern silicon process. The result is that fewer and fewer chips are produced in larger and larger volumes, stif...

In this paper, we develop a multiscale mortar multipoint flux mixed finite element method for second order elliptic problems. The equations in the coarse elements (or subdomains) are discretized on a fine grid scale by a multipoint flux mixed finite element method that reduces to cell-centered finite differences on irregular grids. The subdomain grids do not have to match across the interfaces....

Unreinforced masonry (URM) structures are known to be rather vulnerable to seismic loading. Modern URM buildings with reinforced concrete (RC) slabs might, however, have an acceptable seismic performance for regions of low to moderate seismicity. In particular in countries of moderate seismicity it is often difficult to demonstrate the seismic safety of modern URM buildings by means of force-ba...

The friction behavior of mortar–polymer–steel debonding interfaces was experimentally investigated to support numerical simulation buckling-restrained braces (BRBs). Characteristic contact and slip demands were developed using two-dimensional Abaqus models inform a full-scale test program. A stabilized dynamic coefficient 0.065 observed for reciprocating two-way sliding at the reference bearing...

Did the Internet make international markets more integrated? To address this question, we study long-term price differences and their speed of convergence, based on a unique data base for identical goods sold in both online traditional “brick-and-mortar” distribution channels, covering ten European countries. We find that are closely comparable between channels. Furthermore, converge only sligh...

Among the different non-destructive tests used to carry out an exhaustive survey about the mechanical and durability characteristics of a masonry made of solid tile-bricks, the ultrasonic method has experienced a wide diffusion thanks to its low costs and to its easiness of use; the method essentially consists in detecting the propagation velocity of ultrasonic pulses propagating through a soli...

We consider elliptic problems with discontinuous coefficients discretized by FEM on non-matching triangulations across the interface using the mortar technique. The resulting discrete problem is solved by a FETI–DP method using a preconditioner with special scaling described in Dokeva, Dryja and Proskurowski [to appear]. Experiments performed on hundreds of processors show that this FETI–DP mor...

Abstract. This study adopts an enhanced multiscale approach to investigate the effects of damaging process on structural behavior masonry vaults with regular texture, in view their safety assessment. The model, recently developed by authors, links two different models at macro and microscale, exploiting advantages each formulation. At macroscopic level a homogeneous Mindlin-Reissner shell is mo...
