SOME APPLICATIONS OF THE FINITE ELEMENTS METHOD IN OBSERVATION OF THE MAGNETIC FIELD AND THE THERMAL PROCESSES IN 3 – PHASE INDUCTION MOTORS
Bohos APRAHAMIAN04/01/09Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesThe magnetic field of 3 – phase induction motors is studied using the finite elements method and the professional programming system ANSYS Emag. A model of induction motor, presenting a 20 degree sector of the motor, including two stator and two rotor grooves and two casing gills is studied due to the motor’s symmetry. Full pattern of the motor’s magnetic field is obtained in steady-state regime. All magnetic flux density vector flows are calculated and displayed too. Our study enables us to obtain the magnetic field of all induction motor’s parts in different steady-state working regimes. The transitional and stationary thermal processes in 3 – phase induction motors are studied using the finite elements method and the professional programming system ANSYS Emag too. Full pattern of the motor’s temperature field is obtained as well in transitional and in stationary temperature rate. All heat flows are calculated and displayed too. Our study enables us to obtain the overheat of all induction motor’s parts in different working regimes.Read More -

Mihaela BARHALESCU; Cornel MUNTEANU; Constantin DUMITRACHE04/01/09Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesThe paper shows some theoretical and experimental aspects with reference to the superficial processing using electrical sparking. The tests objective was the superficial processing through sparking process on alloy and non alloy steel samples using a sinter carbide W and Ti electrodes type WCo8 and Ti15Co6. The paper shows metallographic analysis on sparking superficial layers. The analysis was made on NEOPHOT 32 (special microscope) and MC-2 and MC-6 (metallographic microscope). Optic metallographic analyses of sparking superficial layers obtained using “hard” carbide electrodes W and Ti sinterysed had as a result a white layer resistant at normal chemical reactive attack on sample surface. Under this layer a transition zone will form which is obvions at hardened proofs and under “hard” working condition.Read More -
PROPOSAL OF INDICATORS OF SUSTANAIBILITY IN THE SECTOR OF THE MARITIME TRANSPORT
Santiago ORDÁS; Jordi MESSEGUER4/1/2008Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesIt is necessary to establish a system of indicators of the sustainable development in the maritime transport that allow to value the evolution of this sector for the ambience of the sustanaibility. The indicators have to reflect the triple dimension of the sustainable development: economic, social and environmental. These indicators of sustanaibility are hardware of evaluation that they help to construct a society with tuning with the environment. The following paper presents a series of indicators and his expression of calculation for the concrete case of the maritime transport. Some of these proposed indicators use the concept of unit of load of the ship, and in our case the concept of TEU is used, but there might be used the value of tons of load of the ship.Read More -
MULTINATIONAL CREWS AND THEIR POSSIBLE INFLUENCE ON INCIDENTS WHICH ATTEMPT AGAINST ENVIRONMENT IN PORT
Ricardo Rodríguez-Martos DAUER ; Joan Martín MALLOFRE ; Ricardo González BLANCO4/1/2008Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesIn the last decades the number of multinational crews on board ships is increasing. It is a phenomenon that is closely related to Flags of Convenience and the employment of eventual crews of the 3rd World countries, through manning agencies. The problems regarding the join of different languages and cultures, and the questions about professional qualifications, induce us to presume that vessels with multinational crews are expected to suffer more incidents that can damage the environment, that others. In order to carry out with this investigation, it was made an analyse about the flags of the ships entered in Barcelona, Tarragona and Valencia in the last 3 years, to know the percentages of Spanish, foreign and convenience flags. The second step was to get a list of the incidents happened in those ports in the period between 1994 and 1999. From it we have try to establish a relation between risk of incidents and composition of crews. The third step was to collect opinions of ship agents. This paper cannot be used as determinant, but it let us take some first conclusions in order to warn the maritime community about the importance of composition of crews for safety and environment protection.Read More -

DISTORTIONAL SIMULATION IN THE STUDY OF FLOW THROUGH CIRCULAR CONDUITS
Dumitru DINU; Monica STOIAN4/1/2008Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesIn the paper we propose to use the FLUENT program to make a comparison between the results of application normal similitude and distortional similitude in the experiments regarding flow through circular conduits. First, we established the model law, taking into account the physical magnitudes which influence the analyzed phenomena. Afterwards we calculated the scales of these physical magnitudes for normal similitude (one geometrical scale) and distortional similitude (two geometrical scales). Using FLUENT we determined the values of the velocity in the conduit axis, putting the pressure parameters and the dimensions of the conduit according to the two cases of similitude. Finally, we compared the “experimental” results with theoretical results, calculated by application of scale of physical magnitudes.Read More -

In the beginning are proven the limited capabilities of the market mechanisms to stimulate the creation of high quality educational outcomes. After that are revealed the benefits from reciprocal relations in higher education institutions and development of a system of altruistic moral norms, which turn universities into communities centered on the cooperation, tolerance and solidarity values. Next the paper considers the role of social capital for increasing educational revenues and decreasing the transaction costs and personnel expenditures. Finally the question of social capital accumulation sources is analyzed. The latter are sought in the choice of the social enterprise as an organizational form and adopting those management structures that stimulate freedom and equality among the members of higher education institutions.Read More -
APPROXIMATE SOLUTIONS TO AN APPROPRIATE MODEL EQUATION FOR FINITE-AMPLITUDE WAVES ON SHALLOW WATER SURFACES
Dumitru DELEANU4/1/2008Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesNonlinear phenomena play a crucial role in applied mathematics and physics. The results of solving nonlinear equations can guide us to know the described process deeply. Because it is difficult to obtain the exact solution for these problems, we can use one of the standard methods for solving nonlinear differential equations. In this paper, we apply the variational iteration method (VIM) for finding approximate solutions of the Korteweg-de Vries (KdV) equation, which describes the propagation of finite-amplitude waves in shallow water surfaces. The obtained solutions are compared with exact solution. The results are in good agreement, especially for higher iterations.Read More -

SOME APPLICATIONS OF NANODIMENSIONAL FUNCTIONAL LAYERS IN SHIP ELECTRONICS
Bohos APRAHAMIAN4/1/2008Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesNanostructured materials have a number of desirable thermal, electromagnetic and mechanical properties and can play a significant role in improving key parameters of the ship electronic equipment. Our recent work consist the obtaining of resistive elements, formed upon electroinsulated plates of alumina ceramics with nanodimensional conductive layers. Different layer compositions are experimented and the change of the electrical resistance due to the temperature rate is studied. The elements are applied as sensors in electronic bridge circuit for positive temperature measuring. In recent years, nanoscaled magnetic materials have received much attention too, due to the fundamental interest in the unique magnetic property different from that in the bulk phase and to their promising applications in technology such as in the high-density magnetic storage. The magnetic properties are usually dictated by the size, dimension, shape, structure, morphology of the constituent phases, along with the type and strength of magnetic coupling between them. The magnetic metals, including Fe, Co, Ni, and their related alloys in low dimensional form, are one of the most important subjects to study. Nanostructured materials can improve key antenna parameters like radiation-efficiency, directivity and mechanical robustness. Electromagnetic absorption properties can be controlled by changing the particle size distribution in nano-materials and application-specific, tailored materials can be produced.Read More -

Data collection was carried out by applying the focus-group method for a sample of 51 participants. The focus-group grid consisted of several preliminary questions, six open questions that allowed the formative valences of the self-analysis of the teaching activity to be outlined, and a concluding question. In this paper, we have focused on the ways in which self-analysis of teaching activity can be used and the contribution of this process to teachers' self-perceived professional progress. Following the recording of the answers, their analysis and coding, aspects such as: the permanent reporting of teachers to students, the achievement of educational goals, the optimal and prompt change of teaching strategies, the use of self-reflective questions, didactic self-regulation and the efficiency of the instructional-educational approach, considered as prerequisites for the practice of self-analysis of teaching activity, were highlighted. On the other hand, we found that all 51 primary school teachers claim that self-analysis of teaching activity contributes significantly to their self-perceived professional progress.Read More -
Organizational Incivility: Patterns and Profiles among Teaching Staff
Cătălina Ceban-Muzîcantu30-Jun-25https://conferinta.e-nformation.ro/wp-content/uploads/2024/07/Proceedings_Romanian_International_Conference_for_Education_and_Research13.pdfEducationOrganizational incivility is a type of behavior that can be frequently encountered in the workplace environment. Even if it can have a low intensity and is vaguely perceptible, studies in recent years find that these manifestations can be contagious and over time can become part of the organizational culture. It usually manifests itself through behaviors such as: taking credit for someone else's work, unpleasant emails, compliments with ambiguous meaning, which cumulatively affect the well-being of employees at work. Distinct characteristics of the target (victim), the instigator and the witness were noted, taking into account criteria such as: position in the organizational hierarchy, certain personality traits and behavioral reactions. The teaching staff have not been speared of manifestations of workplace incivility as it can be seen through the interviews that it is a frequent occurrence.Read More -
The role of intergroup apologies and intergroup contact in promoting reconciliation in severe intergroup conflicts
Alin Semenescu30-Jun-25https://conferinta.e-nformation.ro/wp-content/uploads/2024/07/Proceedings_Romanian_International_Conference_for_Education_and_Research13.pdfEducationOne of the big challenges of social psychologists is how to contribute to solving existing intergroup conflicts. The present experiment (N = 178) was conducted in the context of a severe intergroup conflict between Romanians (the privileged group) and Romas (the underprivileged group) and investigated the effects of intergroup apologies, intergroup contact and their interaction on intergroup forgiveness and trust. Perceived sincerity of the apology and perceived typicality of apologizing representatives were studied as moderators of apology’s effects. Results show that intergroup contact was positively associated with forgiveness and trust in the perpetrator group, while intergroup apologies had a direct effect only on trust. Apology’s effect on trust was moderated by both perceived sincerity of the apology and perceived typicality of the apologizing representative, while its effect on forgiveness was moderated only by perceived sincerity. Theoretical and practical implications are discussed.Read More -

Because of its capacity to generate content based on prior experiences, artificial intelligence has immense impact and potential. The educational system has to adapt to the changing needs of society by incorporating new technologies into the lessons taught. Artificial intelligence has the ability to improve learning for students in a number of ways, one of which is by giving teachers precise feedback and by offering students with learning experiences that are tailored and adaptable. Artificial intelligence can be used to boost student engagement and motivation, which may be used to inspire students to take responsibility for their education and to be committed to achieving academic success. Also, students need to acquire the abilities employers will be looking for in the workers of tomorrow in an increasingly algorithmic and digital environment. Many companies already employ artificial intelligence for tasks such as writing product descriptions, developing customized products, customer support, and targeted, tailored content for their consumers. The education system will have to teach students to co-create together with artificial intelligence as it becomes more integrated into business, products, and serviceRead More -

Camelia Tulcan Javier Rodrigo Ilarri Luis Manuel Sánchez-Ruiz Nuria Llobregat-Gómez María Elena Rodrigo-Clavero Ioana Mihaela Balan Yanislav Zhelev Mariya Zheleva Iuliana Chilea Speranta Stomff Mihaela Stancu Rositza Georgieva5-Nov-24https://conferinta.e-nformation.ro/wp-content/uploads/2025/01/Proceedings_ALLS_14_3_compressed.pdfEducationThe growing complexity and globalization of industries highlight the crucial role of standardization in ensuring quality, interoperability, and innovation across sectors. Europe needs the best standardization experts to pursue its global standard-setting ambitions to safeguard a digital, green and resilient single market. As industries evolve, the demand for experts well-versed in standards and their implementation becomes increasingly urgent. The strategic importance of standards requires more attention and promotion. Students do not often get the value of learning about standardization until a later stage of their career. At the same time, the industry, public authorities, and societal stakeholders need experts to assist them in the standardization process. Increasing the incentives for students and universities to engage in standardization depends on market attractiveness and societal perspective on standardization This paper presents an example of best practice of collaboration between national standardization bodies of Romania, Bulgaria, Universitat Politècnica de València, Spain and University of Life Sciences "King Mihai I" from Timisoara, Romania in developing micro-credential courses. This paper investigates whether the integration of standardization into educational frameworks represents a new and necessary vision for developing the next generation of experts.Read More
