This paper presents the vibration analysis and suppression control of a moving elevator string. A dynamic formulation is proposed first for the non-linear vibrations of the string with time-varying length and a weight attached at the lower end. The permanent magnet (PM) synchronous servo motor is us

## Abstract A digital elevation model (DEM) of a fluvial environment represented landform surface variability well and provided a medium for monitoring morphological change over time. Elevation was measured above an arbitrary datum using a groundβbased threeβdimensional tacheometric survey in two r
The great scatter of fatigue test results demands special planning and evaluation. A development of the W6hler diagram is presented which splits up the fatigue ranges into ones of finite endurance, transition and infinite endurance. The two types of the W6hler diagram with this conception are shown.
This paper describes a piece of equipment which has been specially designed to permit the study of the evaporation of single liquid drops in an immiscible liquid at elevated pressures up to the order of 1 MPa. It is equipped with a piezoelectric discharger for yielding nucleation in each drop and wi
## Abstract The purpose of this article is to introduce several results concerning the analysis and synthesis of reliable or invulnerable networks. First, the notion of signed reliability domination of systems is described and some applications to reliability analysis are reviewed. Then the analysi
