In the recent literature on optimal monetary policy, policymakers are assumed to know the true model of the economy and observe accurately all relevant variables. The sources and properties of economic disturb...
Chapter and Conference Paper
When dealing with high-speed trains, the effects of the aerodynamic forces acting on the vehicle as a consequence of cross wind are one of the most critical problems connected with running safety. Moreover thi...

The Tacoma Bridge disaster, in the 40s, has opened a new interesting chapter in the study of suspension bridges. This is still open today, as the need of making connections easier leads to bridge spans which a...
Article
Using two-phase sampling scheme, we propose a general class of estimators for finite population mean. This class depends on the sample means and variances of two auxiliary variables. The minimum variance bound...

Extrapyramidal adverse effects (EPAs) due to neuroleptic treatment are routinely treated with anticholinergic antiparkinsonian drugs (APDs). We studied the use of these drugs in the general population exposed ...

Chapter and Conference Paper
The main purpose of permanent monitoring of rotating machinery is the early detection of fault conditions. This goal can be achieved by identifying abnormal changes in current data in respect with reference va...
Chapter and Conference Paper
A 90MW gas turbine and a generator connected by means of a synchro-self-shifting joint, showed high level of vibration at the intermediate shaft, caused by a supporting structure resonance. The measurements pe...

Cerebral blood flow (CBF) and cerebral plasma volume (CPV) were measured under steady-state hyperglycemic conditions in the hemispheres and brainstem-cerebellum of conscious rats. There groups of hyperglycemic...
Chapter
The aim of this paper is to illustrate a method to compute oil film stiffness and dam** equivalent coefficients depending on the journal amplitudes of vibration. These coefficients can be used in a program f...
Chapter
This paper is aimed at illustrating the state of art and the research guidelines used in machinery diagnostics by examining, in particular, the case of thermoelectric plants. Some existing diagnostics examples...
Chapter
The interaction between the rotor and the supporting structure (foundation) plays an important role in rotor dynamics. From this point of view two effects can be considered separately. The first one is connect...
