Finite element modeling and random vibration analysis of BGA electronic package soldered using lead free solder alloy − Sn-1Cu-1Ni-1Ag

International Journal for Simulation and Multidisciplinary Design Optimization, 2019
As a result of the ban of lead from solder joints, many lead-free solder joints were developed. Most of the electronic equipment is subjected to random vibration.

Reaction diffusion processes on random and scale-free networks [PDF]

, 2004
We study the discrete Gierer-Meinhardt model of reaction-diffusion on three different types of networks: regular, random and scale-free. The model dynamics lead to the formation of stationary Turing patterns in the steady state in certain parameter ...

Impact of transition metal oxidation state on the multiferroic properties and magnetoelectric coupling strength of BST ceramics

Journal of Asian Ceramic Societies, 2020
Effect of starting Fe precursor (Fe2O3 and Fe3O4) on the multiferroic properties of BST (Ba0.96Sr0.04Ti0.91Fe0.09O3) ceramics has been investigated. Considerable changes in the ferroelectric and magnetic properties of these ceramics were observed.
