Aeroacoustic is defined as the acoustic propagation of sound generated by fluid flow. Different aeroacoustic problems are used to test the computational schemes performance. A new high-accuracy numerical scheme was modified from Runge-Kutta method with more operators and improved factors. The scheme is tested and modified in the present work for benchmark computational aeroacoustic problems. Te...

Howland circuits have been widely used as powerful source for exciting tissue over a wide frequency range. When a Howland source is designed, the components are chosen so that the designed source has the desired characteristics. However, the operational amplifier limitations and resistor tolerances cause undesired behaviors. This work proposes to take into account the influence of the random di...

We propose a water-immersed nucleobase-functionalized suspended graphene nanoribbon as an intrinsically selective device for nucleotide detection. The proposed sensing method combines Watson-Crick selective base pairing with graphene's capacity for converting anisotropic lattice strain to changes in an electrical current at the nanoscale. Using detailed atomistic molecular dynamics (MD) simulat...
