in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...

Removal of degraded concrete during repair activities might have a detrimental impact on the bond strength between and mortar. This research aims to improve bonding in case aggressive removal techniques were used, by singular combined application bacterially induced CaCO3 colloidal nano-silica (CNS) treatments. Water jetting (WJ) jackhammering (JH) compared treatments performed substrates prepa...

this paper analyses and compares the performances of business-to-business e-commerce data quality and service quality among the use of the ‘push’ and ‘pull’ models. rosettanet’s original partner interface processes use the ‘push’ model which suffers from data redundancy when the volume of business-to-business transaction increases. however, when the ‘pull’ model is used, although it reduces dat...

Lizards and insects can strongly attach to walls and then detach applying negligible additional forces. We propose a simple mechanical model of this phenomenon which implies active muscle control. We show that the detachment force may depend not only on the properties of the adhesive units, but also on the elastic interaction among these units. By regulating the scale of such cooperative intera...

Abstract — In CMOS circuit’s design, as the threshold voltage is reduced due to voltage scaling, it leads to increase in sub-threshold leakage current and hence static power dissipation. In this paper we propose a power reduction technique named transistor gating. In this technique two sleep transistors PMOS and NMOS are inserted in between the supply voltage and ground. A PMOS is inserted in b...
