Study of the internal Resonance of a two-Degree-of-Freedom Non-Linear Dynamic System
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper analyses a two- degree- of- freedom dynamic system, by taking
into account its non- linearity. The case of the internal resonance is studied
and, by local analysis, Hopf bifurcations are emphasized. Periodic ...
NDT of Cementitious Materials
(Universitatea "Dunărea de Jos" din Galați, 2006)
The US method presented an automatically extract certain parameters of US
waves, parameters that have been continuously recorded during the mortar
hardening process. Until now, the standard methodes measured only ...
Computer Symulation of the Earthmoving Machine to Pass Over Roughness Road
(Universitatea "Dunărea de Jos' din Galați, 2006)
In this paper the author proposed a model for computer simulation of earthmoving
machine passing over the roughness roads. It's important to know the dynamic
overloads into the bucket rotation system which is frecvently ...
Vibration Measurement Equipment
(Universitatea "Dunărea de Jos" din Galați, 2006)
This paper describes the principles of operation of typical instrumentation
used in the measurement of shock and vibration. It deals with the
measurement of parameters which characterize the total (broad-band)
signal.
Acoustical Telemetry
(Universitatea "Dunărea de Jos" din Galați, 2006)
The work presents a method of position measuring of a mobile body on
straitened areas using the acoustical wave. The advantages of the
acoustical telemetry consist on contactless measurement of the position
and on higher ...
The Approximate Analytical Solutions for the Differential Equations which Desccribe Free Vibrations of Non-Linear Mechanical Systems
(Universitatea "Dunărea de Jos' din Galați, 2006)
The oscillation movement of a mechanical non-linear system is not easy
to solve exactly on analytical way. The approximate solutions are based on
different methods and give different values with different approximation
degree. ...
Assessing and Controlling the Noise in Construction. Romanian and EU Legislation
(Universitatea "Dunărea de Jos" din Galați, 2008)
Exposure to loud noises at work can cause irreversible hearing
damage, workplace accidents and be a contributing factor to other health
problems. Noise-induced hearing loss is the most common reported
occupational disease ...
The Concept of Competitive Management for Manufacturing Systems
(Universitatea "Dunărea de Jos" din Galați, 2008)
Competitiveness is a general characteristic of enterprises, ensuring their viability.
In economic literature, competitiveness is particularly analyzed from an economic
and managerial viewpoint, dealing with or not ...
Measuring and Controlling of Noises and Vibrations Generated by Industrial Sources
(Universitatea "Dunărea de Jos" din Galați, 2008)
This paper describes a methodology for measuring and control of noises
and vibrations generated by industrial sources, such as: construction
activities, equipments which use vibrations into working process, etc. ...
A New Calculating Method of the Reaction Support Groups Used in Rotary Kiln
(Universitatea "Dunărea de Jos" din Galați, 2008)
This paper presents a new analytical method for calculating the reaction of support
rotary kiln, regarded as an indeterminate static problem. It is the Y -Method and
equation of three displacements (using Y loading ...
