Augmented Reality-Applid Informatics Technology to products Maintenance, Repair and Servicing
Ionescu, Ana-Maria; Petrea, Ionel; Marin, Florin Bogdan (Universitatea "Dunărea de Jos" din Galați, 2012)Augmented Reality (AR) enhances a user's perception of the real world by enhancing it with specific objects that are over-imposed to the real objects. The virtual objects display information that the user may use. The ... -
Computer Vision System for Detection of Passenger Sleeping state for Advanced Driver Assistance Systems
Petrea, Ionel; Marin, Florin Bogdan (Universitatea "Dunărea de Jos" din Galaţi, 2014)The goal of this research is to develop an in-vehicle computerized system able to warn the driver, to assess the passenger’s state of sleeping in order to avoid affecting the driver psychologically and induce drowsiness. ... -
Experimental Research Regarding the Obtaining of Obtaining of Friction Elements
Petrea, Ionel; Bașliu, Vasile; Petrea, Ionel; Bașliu, Vasile (Universitatea "Dunărea de Jos" din Galați, 2009)Friction materials are used as bimetallic friction elements, consisting of a friction material layer sintered on a steel backing. Using the electron microscopy techniques (microprobe analyzer) some of the diffusion ... -
Mathematical Model of the Strip Rolling Made of the Sinterized Metallic Powders
Petrea, Ionel; Istrate, Sorin Miltiade (Universitatea "Dunărea de Jos" din Galați, 2005)The minimum-power method has been used to investigate the final ratio soft-layer thickness to tough-layer thickness in bimetals with porous layer rolling. The velocity fields has been determined and the total deformation ... -
Modelling of the Flow and Deformation Fields at teh Profiles Rolling by Field Lines Method
Cănănău, Nicolae; Petrea, Ionel; Corobete, Gheorghe (Universitatea "Dunărea de Jos" din Galați, 2005)This paper presents a method for modeling of the rolling process based at the deformable continuous medium mechanics, the theory of field lines. The rolling of the profiles and plates may be evaluated as the plane strain ...
