Abstract: Observer theory is applied to design an active controller for a machine tool such as a lathe to reduce the chatter tendency and forced vibration effects that can be detrimental to a workpiece ...

Abstract: The use of feedback control to regulate the position of the cutting tool relative to the workpiece on a machine tool such as a lathe is examined with respect to the reduction of vibratory ...

Abstract: This paper presents the experimental results and discusses the track of the maximum power point on the current-voltage curve of a PV module due to changes of the illumination level and ...

Abstract: This paper covers the case history of hydrogen damage in a relatively low-pressure boiler (1250 psi). Two failures are discussed, as well as the pertinent facts concerning boiler operation, ...

Abstract: This paper reviews the experimental activities that were performed in recent years at the Department of Mechanical and Nuclear Engineering (DCMN) of the University of Pisa, mainly during research ...

Abstract: The problem of a thin isotropic elastic plate containing an axisymmetric hole, under simple tension at infinity is considered. The method used is to extend the plate theories which have appeared ...

Abstract: Many unique advantages have stemmed from the use of aircraft-type gas turbine power plants in selected marine propulsion applications; and, as expected, special problems have arisen because of ...
