The formation of droplets in microchannels (droplet microfluidics) has a large number applications, such as micro-dosing and gas meters. This paper considers the dynamics direct inverse emulsions based on water, polydimethylsiloxane, synthetic mineral oil microfluidic chips two technologies: glass–parafilm–glass sandwich structures removable scaffold silicone compound. It is shown that wettabil...

The bending behavior of composites sandwich plates with multi-layered laminated face sheets has been investigated, using a new four-nodded rectangular finite element formulation based on a layer-wise theory. Both, first order and higher-order shear deformation; theories are used in order to model the face sheets and the core, respectively. Unlike any other layer-wise theory, the number of degre...

Liver tissue constructs with excretory function are crucial to developing realistic hepatocyte models for engineering effective bioartificial liver-assisted devices and for modeling the in vivo tissue. Current hepatocyte in vitro models suffer from limited or inefficient hepatocyte repolarization, which results in poor removal of xenobiotics and other waste products from the cells. We hypothesi...

This introduction to the object-orientation features of the R package sandwich is a (slightly) modified version of Zeileis (2006), published in the Journal of Statistical Software. Sandwich covariance matrix estimators are a popular tool in applied regression modeling for performing inference that is robust to certain types of model misspecification. Suitable implementations are available in th...

Carbon fiber-synthetic foam core sandwich composites are widely used for many structural applications due to their superior mechanical performance and low weight. Unfortunately these structures typically have very poor acoustic performance. There is increasingly growing demand in mitigating this noise issue in sandwich composite structures. This study shows that marrying carbon fiber composites...

The mechanical response and fracture of metal sandwich panels subjected to multiple impulsive pressure loads (shocks) were investigated for panels with honeycomb and folded plate core constructions. The structural performance of panels with specific core configurations under multiple impulsive pressure loads is quantified by the maximum transverse deflection of the face sheets and the core crus...

A sandwich problem for a graph with respect to a graph property Π is a partially specified graph, i.e., only some of the edges and non-edges are given, and the question to be answered is, can this graph be completed to a graph which has the property Π? The graph sandwich problem was investigated for a large number of families of graphs in a 1995 paper by Golumbic, Kaplan and Shamir, and much su...
