Electrostatic Effects on Linear and Nonlinear Waves in Hanging Film Flows

Linear and nonlinear waves

The study of waves can be traced back to antiquity where philosophers, such as Pythagoras (c.560-480 BC), studied the relation of pitch and length of string in musical instruments. However, it was not until the work of Giovani Benedetti (1530-90), Isaac Beeckman (1588-1637) and Galileo (1564-1642) that the relationship between pitch and frequency was discovered. This started the science of acou...

Electrostatic Discharge Effects in Thin Film Transistors

Cover page: The cover photo is taken during Liquid Crystal Hot Spot measurements on a fingerprint sensor. Thank you! It rained for four years, eleven months and two days. There were periods of drizzle during which everyone put on his full dress and a convalescent look to celebrate the clearing, but people soon grew accustomed to interpret the pauses as a sign of redoubled rain. This is how a ch...

Linear and Nonlinear Dust Acoustic Waves in Quantum Dusty Electron-Positron-Ion Plasma

The behavior of linear and nonlinear dust acoustic waves (DAWs) in an unmagnetized plasma including inertialess electrons and positrons, ions, and mobile positive/negative dust grains are studied. Reductive perturbation method is employed for small and finite amplitude DAWs. To investigate the solitary waves, the Korteweg–de Vries (KdV) equation is derived and the solution is presented. B...
