Lens cement failure

Submitted by bouabidz on

Hello all, I am having problem with one of our lens doublets getting decemented. we have been cementing this lens for many years and we did not do anything different. Recentely we start seeing this lens decementing. we use NO61 and NO65 (UV curing). Any help of how to prevent this problem from happening again will be very much appreciated.

 

Thank you,

Need help with understanding Thin Plate Splines as Radial Basis function for Meshfree simulation

Submitted by VardhiniV on

I want to try applying TPS as the RBF for the simulation of groundwater flow and transport. but the i'm getting error because of zeros in diagonal elements in the global matrix. Please help with the shape function

Postdoctoral Associate Position Available at Northwestern University

Submitted by keten on

A postdoctoral associate position is available at the Computational Nanodynamics Group at Northwestern University. This research project focuses broadly on atomistic and multi-scale modeling and simulation of the mechanics and dynamics of organic, biological and bioinspired nanomaterials. The post-doctoral researcher will have the opportunity to investigate diverse issues related to mechanics and transport phenomena in emerging nanostructured materials.

Dynamic model of ion and water transport in ionic polymer-metal composites

Submitted by Bo Li on
In the process of electro-mechanical transduction of
ionic polymer-metal composites (IPMCs), the transport of ion and water molecule
plays an important role. In this paper, the theoretical transport models of
IPMCs are critically reviewed, with particular emphasis on the recent
developments in the latest decade. The models can be divided into three classes,
thermodynamics of irreversible process model, frictional model and Nernst-Planck
(NP) equation model. To some extent the three models can be transformed into
each other, but their differences are also obvious arising from the various
mechanisms that considered in different models. The transport of ion and water
molecule in IPMCs is compared with that in membrane electrode assembly and
