Transducer with Phase Modulation and Adjustable Sensitivity
(Universitatea "Dunărea de Jos" din Galați, 2011)The work presents an easy converter in order to be used at little displacement. The circuit gives two electrical signals with the same frequency and with different phases, dependent on the displacement.Both signals go ... -
Transducer-Shape Optimization for Angle Estimation of a Broadbrand Monaural Sonar System
("Dunarea de Jos" University of Galati, 2004)In this paper we describe a procedure for the search of the optimal trans-ducer geometry for a monaural, broadband sonar system. We restrict ourselves to a simple transducer morphology that can be technologically realized: ... -

(Universitas Galatiensis, 2009-06)Romania, Romanian economic agents have become in recent years present ever more active in world trade. Association agreements agreed with the European Union and beyond, opening Romania and Romanian participants ... -
Transparent and Conducting TIN Oxide Thin Films Deposited by Spray Pyrolysis
(Universitatea "Dunărea de Jos" din Galați, 2009)The chemical spray pyrolysis technique has been one of the major techniques to deposit a wide variety of materials in thin film form, for different applications. The most important control parameters for obtaining good ... -
Treating Propriety Through Cutting of Metals and Alloys in Cryogenic Condition
(Universitatea "Dunărea de Jos" din Galați, 2003)It is known that a base function of cutting environments is to cool the cutting tools, the tooled area and the material that is removed under the shape of chip. But it is also known that beginning with the increase of ... -
Treatment of Ammonia Wastewater by Ultrasound. Part I: The Influence of the Ultrasound energy on the ultrasound Bath Temperature
(Universitatea "Dunărea de Jos" din Galați, 2015)The industrial ammonia water decontamination depending on the sample temperature is monitored by this study. The treatment was conducted by the UP100S ultrasound generator (Hielscher Ultrasound Technology, Germany), operating ... -
Treatment of Wastewater Resulting from the Mettallic Coatings Process
(Universitatea "Dunărea de Jos" din Galați, 2016)The technological cleaning processes of steel strip surfaces used in metal coatings require organic or inorganic chemicals with a high risk of toxicity. To avoid pollution, the water resulting from these processes must ... -
Trei dimensiuni ale inegalității de șanse
(Universitatea „Dunărea de Jos” din Galați, 2023)Această disertație prezintă rezultatele a trei studii, fiecare explorând o dimensiune distinctă a inegalității de șanse, și își propune să aducă următoarele contribuții: În primul rând, se analizează dacă circumstanțele ... -
Trei scriitoare engleze contemporane. Subminarea canonului literar din interior. (Three contemporary women writers. Within and against the canon.)
(Universitatea "Dunărea de Jos" din Galaţi, 2013)Atunci când Harold Bloom a afirmat că standardul unic prin care se poate judeca dacă o operă literară merită un statut canonic este „măreția”, a omis caracterul subiectiv al acestui criteriu. Cine este mai în măsură să ... -
Tribocorrosion-insight Into Material Degradation in Specific Environments
(Universitatea "Dunărea de Jos" din Galați, 2014)Tribocorrosion is an irreversible surface degradation mechanism of a metallic and/or non-metallic material as a result of its physicochemical and mechanical interactions during relative motion (friction, sliding, impact, ... -
Tribological Aspects of Electrode-Elastomer Contact
(UDJG, 2010)Dielectric elastomers (DE) are soft polymers based smart materials that may be potentially employed in applications such as actuation, sensing and energy harvesting. The performance of dielectric elastomer actuators (DEA) ... -
Tribological Behaviour of Molybdenum Disulphide Nanoparticles
(Universitatea ”Dunărea de Jos” din Galați, 2009)l dichalcogenides, are well known for their solid lubricating behaviour. Thin films of MoS2 exhibit extremely low coefficient of friction in dry environments, and are typically applied by mixing in oil, grease or impregnated ... -
Tribological Behaviour of CO-CR-MO and Uhmwpe the Components of Intervertebral Disc Prosthesis
(Universitatea ”Dunărea de Jos” din Galați, 2006)The Intervertebral Disc Prostheses consist of a modular system and his function is based on low intervertebral friction. As a result of friction forces acting to the spine structures, the intervetebral disc prostheses can ... -
Tribological Behaviour of Nitrocarburized Steels After Thermo-Magnetic Treatments
(Universitatea "Dunărea de Jos" din Galaţi, 2008)Two types of steels were subjected to a nitro-carburized thermo-chemical treatment after thermo-magnetic treatments. The structural aspects into the superficial layer of these steels are studied during the friction process ... -
