Energy Dissipation Device Using Fluid Dampers
(Universitatea "Dunărea de Jos" din Galați, 2012)This scientific paper presents a solution that is adequate for the seismic isolation of small and medium size buildings and bridges. Comprising two seismic isolating devices, the described arrangement is suitable ... -
Humidity Determination in Concrete by Using the Dielectric Method
(Universitatea "Dunărea de Jos" din Galați, 2011)The presence of humidity in the building envelope elements decays their structural and technological properties, favours heat losses and, in time, also the deterioration and degradation of the building. In order to avoid ... -
Influence of structure Mass on the Behavior of Seismic Energy Hidraulic Dissipation Devices
(Universitatea "Dunărea de Jos" din Galați, 2012)Since many solutions exist today in the field of structure isolation against the destructive action of earthquakes, the authors present a simple solution that can provide complete protection against shock and vibration ... -
Non-Linear Dynamic Behavior of a Ball Float Valve
(Universitatea "Dunărea de Jos" din Galați, 2012)The dynamic behavior of the spherical body floating in a liquid, part of a ball float valve, is analyzed from the point of view of the dynamic systems theory. The study of the motion illustrates the differences between ... -
On the Control of the Element Finite Meshes with Dimension in Arithmetic Progression
(Universitatea "Dunărea de Jos" din Galați, 2012)The purpose of this article is to present the formulae for calculating the parameters defining the finite element meshes with variable dimensions in arithmetical progression along some user defined paths within the ... -
On the Use of Approximate Numerical and Analytical Methods in Order to solve the Differential Equations that Describe Vibrations of the Mechanical Systems
(Universitatea "Dunărea de Jos" din Galați, 2012)The paper makes a comparative study on the approximation errors of the solutions of the differential equations of second order using different numerical methods, a study which is assessed by the necessity of numerical solving ... -
Optimazation of Ultrasonic Flow Meters for Crude Oil Metering and Export
(Univeritatea "Dunărea de jos" din Galați, 2012)Ultrasonic flow meters, as all velocity or inference type devices, require an adequate flow stream conditioning in order to assure an accurate performance. Typical flow conditioning consists of straightening the upstream ... -
Performance and Evaluation of Make-To-Order Manufacturing System
(Universitatea "Dunărea de Jos" din Galați, 2012)The system environment provides on-line data on the actions undertaken which, properly analyzed and correlated, will further generate solutions in order to develop said system and make it competitive. The paper aims, ... -
Rotary Screening Bucket Equipment Attachable to the Excavator Arm
(Universitatea "Dunărea de Jos" din Galați, 2012)This paper aims to find a new solution of an equipment with rotary screening bucket attachable to the excavator arm. This equipment is used on a large scale for selecting the building material used on small and medium ... -
Shear Stresses in Beams with Variable Cross Section, Subjected to Non-Uniform Bending
(Universitatea "Dunărea de Jos" din Galați, 2012)The goal of this paper is to present a generalization of the Juravski formula (appropriate for the beams with constant cross section, subjected to non-uniform bending), for the beams with variable cross section. In the ... -
The Dynamic Analysis of the Inrtial Vibrating Screens Modeled as 3DOF Elastic Systems
(Universitatea "Dunărea de Jos" din Galați, 2012)The paper proposes an approach of a 3DOF (3 Degree Of Freedom) dynamic model for the vibrating screens, with the purpose of determining some impartial criteria for the appreciation of dynamic characteristics of the ...
