Active devices, while providing significant reductions in structural motion, typically require large (and often multiply-redundant) power sources, and thereby raise concerns about stability. Passive devices are fixed and cannot be modified based on information of excitation or structural response. Semiactive devices on the other hand can provide significant vibration reductions comparable to those of active devices but with substantially reduced power requirements and in a stable m 606 $aVibration 606 $aDamping (Mechanics) 606 $aStructural control (Engineering) 608 $aElectronic books. 615 0$aVibration. 615 0$aDamping (Mechanics) 615 0$aStructural control (Engineering) 676 $a624.171 676 $a624.176 700 $aCasciati$b Fabio$031624 701 $aMagonette$b Georges$0950612 701 $aMarazzi$b Francesco$0950613 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910143745403321 996 $aTechnology of semiactive devices and applications in vibration mitigation$92149271 997 $aUNINA LEADER 02004oam 2200517M 450 001 9910716135203321 005 20200213070930.6 035 $a(CKB)5470000002518765 035 $a(OCoLC)1065613134 035 $a(OCoLC)995470000002518765 035 $a(EXLCZ)995470000002518765 100 $a20071213d1926 ua 0 101 0 $aeng 135 $aurcn||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aTo provide for the collection and publication of statistics of tobacco by the Department of Agriculture.
