Parallelization by Simulated Tunneling
(USENIX Association, 2012)
As highly parallel heterogeneous computers become commonplace, automatic parallelization of software is an increasingly critical unsolved problem. Continued progress on this problem will require large quantities of information ...
Response of Metallic Pyramidal Lattice Core Sandwich Panels to High Intensity Impulsive Loading in Air
(Elsevier, 2011)
Small scale explosive loading of sandwich panels with low relative density pyramidal lattice cores has been used to study the large scale bending and fracture response of a model sandwich panel system in which the core has ...
Localized Ridge Wrinkling of Stiff Films on Compliant Substrates
(Elsevier, 2012)
Wrinkling of thin stiff films on thick compliant elastomeric substrates subject to plane strain compression is considered for cases in which the substrate is pre-stretched prior to film attachment. Advanced wrinkling modes ...
From Wrinkles to Creases in Elastomers: The Instability and Imperfection-Sensitivity of Wrinkling
(The Royal Society, 2012)
The stability of the wrinkling mode experienced by a compressed half-space of neo-Hookean material is investigated using analytical and numerical methods to study the post-bifurcation behaviour of periodic solutions. It ...
Wrinkling Phenomena in Neo-Hookean Film/Substrate Bilayers
(American Society of Mechanical Engineers, 2012)
Wrinkling modes are determined for a two-layer system comprised of a neo-Hookean film bonded to an infinitely deep neo-Hookean substrate with the entire bilayer undergoing compression. The full range of the film/substrate ...
Periodic Patterns and Energy States of Buckled Films on Compliant Substrates
(Elsevier, 2011)
Thin stiff films on compliant elastic substrates subject to equi-biaxial compressive stress states are observed to buckle into various periodic mode patterns including checkerboard, hexagonal and herringbone. An experimental ...
The Influence of Transient Thermal Gradients and Substrate Constraint on Delamination of Thermal Barrier Coatings
(American Society of Mechanical Engineers, 2013)
A systematic study of factors affecting the delamination energy release rate and mode mix of a thermal barrier coating attached to a substrate is presented accounting for the influence of thermal gradients combined with ...
Combining Control-Flow Integrity and Static Analysis for Efficient and Validated Data Sandboxing
(Association for Computing Machinery, 2011)
In many software attacks, inducing an illegal control-flow transfer in the target system is one common step. Control-Flow Integrity (CFI) protects a software system by enforcing a pre-determined control-flow graph. In ...
Coherence of Nitrogen-Vacancy Electronic Spin Ensembles in Diamond
(American Physical Society, 2010)
We present an experimental and theoretical study of electronic spin decoherence in ensembles of nitrogen-vacancy (NV) color centers in bulk high-purity diamond at room temperature. Under appropriate conditions, we find ...
Cellular Hydraulics Suggests a Poroelastic Cytoplasm Rheology
(Nature Publishing Group, 2013-01-07)
The cytoplasm represents the largest part of the cell by volume and hence its rheology sets the rate at which cellular shape change can occur. Recent experimental evidence suggests that cytoplasmic rheology can be described ...
