Dextrous Hand-Grasping Preshaping
(Universitatea "Dunărea de Jos" din Galați, 2007)
The research conducted in human grasping have emphasized three main phases: the
visual location of the target, when the object is analyzed an recognized, the reaching
phase of grasping, when the hand preshapes in order ...
The Energetic Analysis of Hydraulic Actuators Used for Small Mobile Cranes
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents applied usual solutions to the action of light self-propelled
cranes, up to 6 tf. It is accomplished an analysis of usual solutions of action and
more over of comanding the equipment. It is analized ...
A Model of the Mechanical Waves in Curved Bars
(Universitatea "Dunărea de Jos" din Galați, 2007)
The different classical models of the mechanical waves in bars
cover every a single type of the wave, respectively only longitudinal,
transversal, inflexion or torsion wave and only in a rectilinear bar, every
with his ...
Study of Noise Produced by Elevators Inside Buildings
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper studies the way in which elevators movement produces work
perturbing noises. The studies were made on two types of buildings: a
modern building, with noiseless elevators and another one with old
elevators. ...
Influence of the Road Dislevels Upon the Traction System of the Self-Propelled Machines
(Universitatea "Dunărea de Jos" din Galați, 2007)
The kinematic response is caused by run away about the equipment of the
movement modeled in the mechanic system with degree of freedom. The kinematic
excitation considered produces harmonic formally to the organ axle of ...

All-Purpose Low Frequency Numerical Filter
(Universitatea "Dunărea de Jos" din Galați, 2007)
A real signal is a complex system with mixed components. In
addition to needed components appear unusable components with different
origin, namely noise. The clearance or the reduction of the unwanted
components is ...
The Idenfication (In Simulink) of an Elastic
(Universitatea "Dunărea de Jos" din Galați, 2007)
In this paper is realized the identification of an elastic system with one degree of
freedom, for which we experimentally pick up (in SIMULINK) the resonance curve.
The system parameters (m, c, k) are determined using ...

This article describes the effects of workplace noise and outlines the
main steps that should be taken to reduce and control noise at work.
Exposure to noise at work can harm workers’ health. The most wellknown
effect ...
The Impact of Occupational Noise on the Workers. Romanian and EU Legislation
(Universitatea "Dunărea de Jos" din Galați, 2007)
Noise is most obviously a problem in industries such as manufacturing,
mining and construction but it can also be an issue in a wide range of other
working environments like energy, transports, call centers, schools,
orchestra ...
