A simple but accurate analytical acoustic transmission analysis (ATA) is developed for evaluating the acoustic absorption of the multi-layer acoustic absorber. Unlike other analytical approaches available in literature, the present ATA can deal with the multi-layer acoustic absorber containing sever

## Abstract **Summary:** Hydrophilic acrylic nanofibers were prepared from alkaline hydrolysis of hydrophobic polyacrylonitrile (PAN) nanofibers. Water contact angle, pore volume, and liquid retention capacity of PAN nanofibrous membranes were measured to determine their dependence on hydrolysis pa

To improve the performance of a non-linear shock isolator, four di!erent alternatives are being considered and compared. These are (i) an isolator with a Coulomb damper, (ii) a three-element isolator, (iii) an isolator along with vibration absorber and (iv) a two-stage isolator. Three di!erent types
