Deriving glacier outlines from satellite data has become increasingly popular in the past decade. In particular when glacier outlines are used as a base for change assessment, it is important to know how accurate they are. Calculating the accuracy correctly is challenging, as appropriate reference data (e.g. from higher-resolution sensors) are seldom(More)
Interfacial delamination in encapsulated silicon devices has been a great reliability concern in IC packaging. Experimental testing of a transparent quad flat no leads package is carried out with the goal of studying the delamination characteristics and investigating the viability of cohesive zone modeling in simulating delamination patterns and trends. The(More)
Interfacial delamination in encapsulated silicon devices has been a great reliability concern in IC packaging. Experimental testing of a transparent Quad Flat No Leads Package (QFN) was carried out with the goal of studying delamination characteristics and investigating the viability of cohesive zone modeling (CZM) in simulating delamination patterns and(More)
We present a stability map which predicts the domains of shear instability due to grain rotation in nanocrystalline materials. The onset of this mode of instability is influenced by grain-size-dependent mechanisms and the length-scale of intergranular interaction. The map shows the grain size regimes that are inherently susceptible to this mode for a range(More)
In this work, hierarchical magnesium based composites with a micro-architecture comprising reinforcing constituent that is a composite in itself were fabricated using powder metallurgy route including microwave assisted rapid sintering technique and hot extrusion. Different level-I composite particles comprises sub-micron pure aluminum (Al) matrix(More)
In order to improve the properties of metallic glasses (MG) a new type of MG structure, composed of nanoscale grains, referred to as nanoglass (NG), has been recently proposed. Here, we use large-scale molecular dynamics (MD) simulations of tensile loading to investigate the deformation and failure mechanisms of Cu64Zr36 NG nanopillars with large,(More)
The macroscopic responses of synthetic and natural filamentous networks are determined by a combination of microstructure and filament properties. Biofilament networks such as those of actin and fibrin have become vehicles for studying important concepts in mechanics such as rigidity percolation, linearity and nonlinearity, isotropy and anisotropy, affinity(More)
