Semi-Planetary Rolling and Changes of Fine Structure and Microstructure
(Universitatea "Dunărea de Jos" din Galați, 2007)The strain intensity in the proximity of planetary cylinder, in the case of semi-planetary rolling is greater than in the proximity of the massive cylinder. This fact leads at the variation of the microstructure and fine ... -
Separarea și caracterizarea unor compuși organici din soiuri românești de plante aromatice
(Universitatea „Dunărea de Jos” din Galați, 2023)Plantele au reprezentat surse de hrană dar și de medicamente încă din cele mai vechi timpuri [1]. În medicina tradițională se folosesc plantele atât pentru proprietățile lor curative, cât și pentru prevenirea unor boli ... -

Setting the Optimum Angle of Solar Collectors Settlement
(Universitatea "Dunărea de Jos" din Galați, 2013)The performance of any solar energy system depends very much on the availability of solar radiation and the orientation of solar collectors. Solar collectors need to be inclined at the optimum angle to maximize the ... -
Setting up a guarentee suficient to ensure the payment of debts (customs) for goods placed under a common transit procedure / community
(Universitatea "Dunărea de Jos" din Galaţi, 2009-01)The customs duties and other taxes applicable to goods shall be temporarily suspended if the goods are placed under the common transit / community. To ensure the payment of customs duties and other charges resulting from ... -
Several reflections over universal justice
(Universitatea "Dunărea de Jos" din Galați, 2009-01)The idea of universal justice suggests a justice that includes both the trial and complementary activity of tracking and enforcement of judgments exercised by a single state whose organs would make abstraction of where the ... -
Severe Plastic Deformation an Advanced Method for Nanostructuring Shape Memory Alloys
(Universitatea "Dunărea de Jos" din Galați, 2007)Severe plastic deformation (SPD) is an advanced plastic deformation. In this process nanostructuring metals and alloys may be produced. Nanostructured shape memory alloys are associate with a very high strength, toughness, ... -
Severe Plastic Deformed Pure Aluminum by Equal Channel Angular Pressing
(Universitatea "Dunărea de Jos" din Galați, 2009)Samples of an aluminum alloy were subjected to an equal channel angular pressing (ECAP) at room temperature for one pass. For the several specimens severe plastic deformation process was interrupted to observe the material ... -
Shear Stability as Oils’ Performance Indicator
(Universitatea ”Dunărea de Jos” din Galați, 2008)The paper presents a comparative analysis between the shear stability tests results and four ball tests results for some industrial oils. This correlation is used for establishing the way how the mechanical solicitations ... -
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 ... -
Siderurgy Slags Recovery in Building Industry
(Universitatea "Dunărea de Jos" din Galați, 2014)During the metallurgical processes of iron and steel elaboration, besides the basic products, it results a serious of secondary products (wastes) in high quantities but with a high recycle – recovery potential, and their ... -
Siemens PLM Solution Applied to the Design of Agriculture Facilities and Equipment
(Universitatea "Dunărea de Jos' din Galați, 2014)This paper presents a brief description of the SIEMENS PLM solution and its application to the design of machinery and equipment for agriculture. Also it is shown in detail the concept of Product Lifecycle Management ... -
Sift Based Algorithm for Point Feature Tracking
("Dunarea de Jos" University of Galati, 2007)In this paper a tracking algorithm for SIFT features in image sequences is developed. For each point feature extracted using SIFT algorithm a descriptor is computed using information from its neighborhood. Using an algorithm ... -
Silica thin Films Obtaining by Sol-Gel Dip Coating with Controlled Optical Properties
(Universitatea "Dunărea de Jos" din Galați, 2014)Transparent oxide films are widely employed as antireflection or high reflection coatings, band-pass filters and narrow-band-filters in various optical and electronic devices. The performances of these devices are based ... -
Simple Approach for Induction Motor Control Using Reconfigurable Hardware
("Dunarea de Jos" University of Galati, 2002)The paper deals with rotor-field-oriented vector control structures for the induction motor drives fed by the so-called tandem frequency converter. It is composed of two different types of DC-link converters connected ... -
A Simple Device for Modelling Bioarticular Joint Friction
(UDJG, 2011)In this paper a simple device for modelling bioarticular friction is presented. The experimental device serves to simulate the movement as it would take place in a knee joint. Key components of the experimental device are ... -
A Simple Load Power Estimator for Quasi-Direct AC-AC Converter System
("Dunarea de Jos" University of Galati, 2003)In this paper a simple load power estimator for the three-phase quasi-direct acac converter system is reported. Since the ac-ac converter control by means of pulsewidth modulation (PWM) is based on the power balance ... -
Simularea în timp real a comportamentului echipamentelor pentru exploatarea sistemelor critice
(Universitatea "Dunărea de Jos" din Galați, 2013)Automatizarea proceselor este, în acest moment, prezentă în toate domeniile unei economii performante. Nu se mai poate discuta de performan$ă fără să se ia în calcul folosirea unor sisteme automate capabile să efectueze ...
