Temperature, Frequency, and Young’s Modulus of a Ching

open access: yesInternational Scholastic Journal of Science, 2022
The frequency and Young’s Modulus of a Thai ching were studied at temperatures ranging from -20 ̊C to 47 ̊C. It was found that both of these values decreased with temperature. This study also demonstrates the validity of a method of determining the Young’

A Survey Paper on Semiconductor Technology based Dual Modulus Prescaler

open access: yesInternational Journal of Computer Applications, 2013
CMOS refers to both a particular style of digital circuit design and the family of processes used to implement that circuitry on an integrated circuit (chips). Due to the low power dissipation by the MOS devices, the use of them is quite prominent in the VLSI. Semiconductor technology based Dual Modulus Prescaler is to be fabricated in 90 nm technology.

Using resonance to measure the independent elastic constants of problematic materials such as elastomers [PDF]

open access: yesJASA Express Letters, 2021
The determination of the elastic constants for a solid material may be conveniently accomplished by measuring resonances corresponding to the elastic normal modes of a sample. Isotropic materials should be particularly straightforward, since they involve
