Experimental Research about Adjusting the Exposure Time and Power Level of Microwaves for Industrial Applications

This paper shows some possibilities to adjust the exposure time and output power of a given microwave device according to the process to be executed, taking into account the special operating conditions of the magnetrons and the efficiency of the microwave device. Since the exposure time is rather easy to set by means of timers, the microwave power level is difficult to modify because of the magnetron requirements voltage, current, magnetic field which must be carefully observed in order to ensure reliable operation. The research has been carried out at the University of Oradea and INCDTIM Cluj-Napoca, during the activities of the Microwave Collective of the University of Oradea and during the preparation of the doctoral thesis of Mr.Ursu.

The constructive solution for load station is new and original and it was designed and effective produced in the Faculty of Engineering Management and Technology Laboratory, in order to be use at the flexible manufacturing cell for the loading and unloading of the working parts and tools by means of ABB robot IRC 1600.

New Tendency of Machine Tool Study Based on Virtual Machining Software Applied at University of Oradea

The present paper work shows the efforts of the research group from University of Oradea on the introduction into the educational program at all the levels (bachelor, master and PhD) of the newest method of the machine tool study. By these methods is need to understand the educational stages ( engineering for constructive parts, the machining on CNC milling centre up to 5 axes simultaneous, machining of very complexes parts, the programming of the CNC units, the using of the most advanced CAM software, the programming of the robots into the flexible manufacturing cell, etc.). On the other hand we include here the research activity about the improvement of the performances of the entire flexible cell from University of Oradea laboratory by increasing of the technological experiences. It is necessary to mention that the UO-01 flexible manufacturing cell, based on the horizontal milling centre TMA-AL 550, both were developed by own efforts (retrofitting) at University of Oradea in our faculty (Faculty of Management and Technological Engineering) having the contribution of our research group. The entire concept of these new methods is based on virtual simulation into the 3D space of the functioning in real time of all the components at every technological case. For these targets all the components were modeled at 1:1 ratio in 3D space, including the movements of their movable parts.

Scholar Absenteeism – A Continues Challenge of Contemporary Education

Scholar absenteeism means a temporarily leaving of learning institution by the pupils without the teacher's acceptance and engaging in alternative activities more interesting or profitable. Causes of school absenteeism can be found at the educational institution (educational management incoherent and inconsistent or even aversive teaching style, low level of school culture etc.), at the family (disinterest in scholar situation of son/daughter, refusing to send children to school, the devaluation of formal education, poor material conditions etc.), individual (disengagement, orientation towards profitable activities etc.) and community (social control inappropriate, modest economic and cultural level etc.). Scholar absenteeism could be produce with parents’ consent, or, conversely, without their knowledge, which has very serious effects, both in personal and social education. To limit the phenomenon of school absenteeism, University of Oradea and Bihor County Scholar Inspectorate implemented between 2010 and 2012 a project called SCHOOL, MY CHANCE! co-financed by Social European Found. The objective retained for our paper is to identify the level in which students participating at the project have significantly reduced the number of scholar absences recorded in scholar documents at the end of first year of implementation. The lot of subjects was represented by 100 pupils who study in schools from Avram Iancu, Boge, Carasau, Les and Şuncuiuş, Bihor County. The research methodology was represented by the quantitative analysis of number of absences recorded in scholar grade book after the first year of project implementation, namely the qualitative interpretation of these results from psycho-educational perspective. The results showed us that, due to the involvement of pupils in extracurricular activities, number of absences recorded in scholar grade book decreased significantly to 20% of them, which is an important argument in favour of retaining these pupils in the formal education system.

Education and Research Conceptual Aspects and Operationalization Models

Within the first part of this paper we strive to identify the narrowest and the operational meanings related to the terms of education and research as well as the logical and semantic relationships established between them. Starting from the synthetic and interdisciplinary character of education we can differentiate several important new perspectives regarding the interpretation of the training process. On one hand we apprehend that education can be understood as a transfer of knowledge, as a conveyance of information, but on the other hand, it can be perceived as a complex managerial activity. A series of common aspects by means of which research and education turn out to be in a tangential and meddling relationship are emphasized in the second part of this paper, more clearly when the issue of pedagogical methods is being analyzed. By shaping didactic methods, research and investigation procedures we have suggested and experimented three ways regarding the development of the didactic activities within the Teacher Training Department at the University of Oradea: engaging students who attend a master program in activities of research and in publishing their studies and investigations, the joint elaboration of books and textbooks as well as the employment of experimentation and examination procedures while carrying on the pedagogical practice of students.

Aspects Concerning the Quality Improvement of the Pedagogy of Primary and Pre-school Education Study Programme in Blended Weekend Classes

The study is focussed on the analysis of the variables that influence the academic success of freshman enrolled in the Curriculum Methodology and Theory class for the Pedagogy of Primary and Pre-school Education study programme at the University of Oradea. This class is part of the blended weekend class structure for the programme. The target group had filled-in five online questionnaires. Statistically significant scores were obtained between the variables: evaluation of subject coordinator and tutorial teacher (r=.711, p=.000), evaluation of tutorial teacher and attitude towards academic subject in question (r=.388, p=.034), scores for work task 1 and 2 of ongoing evaluation (r=.583, p=.001), final scores and attitude towards academic subject in question (r=.355, p=.050), final scores and seminar attendance (r=.527, p=.003), final scores and group project (r=.639, p=.000).

Issues on Applying Knowledge-Based Techniques in Real-Time Control Systems

At the time being knowledge-based systems are used in almost all life aspects. The main reason for trying to use knowledge-based systems in real-time control is to reduce cognitive load on users (overload), their application proving to be important when conventional techniques have failed or are not sufficiently effective [1]. The development of automated diagnosis techniques and systems can help also to minimize downtime and maintain efficient output. This paper presents some issues of applying knowledge-based systems to real-time control systems. It describes and analyzes the main issues concerning the real-time domain and provides possible solutions, such as a set of requirements that a real-time knowledge-based system must satisfy. The paper proposes a possible architecture for applying knowledge-based techniques in real-time control systems. Finally, a way of employing knowledge-based techniques for extending the existing automatic control and monitoring system for the geothermal plant from the University of Oradea is presented.

THE “SCHOOL. MY CHANCE!” PROJECT – A CASE STUDY FOR PREVENTING PUPILS’ SCHOOL DROPOUT IN ROMANIA

Pupils’ school dropout could be defined as an early and final abandonment of school before graduation, which prevents the pupil from registering in the following stage of education, losing in this way the possibility of benefiting from a proper and higher education. The statistics show that, unfortunately, in recent years school dropout rates have been increasing among secondary school pupils. The University of Oradea and The Bihor County School Inspectorate, Romania, have implemented a project called “School. My chance!” The aim of the project was to prevent and reduce the phenomenon of early school leaving by 100 pupils. The pupils attended five schools in Avram Iancu, Bogei, Carasau, Les and Suncuius, all village in Bihor, Romania, and were identified with higher school dropout risks. This paper proposes to present the partial results obtained at the end of the first period of the project implementation – the second semester of the 2010 / 2011 school year. The sample was represented by those 100 pupils from the above mentioned schools, who were included in Cognitive Therapy, implemented with the help of the project. The method consisted of analysing and comparing the pupils' school marks at the beginning and at the end of the relevant period. The results proved that, after one school semester, the pupils' marks remained rather unchanged, but in a few specific cases (schools or school subjects) small progresses were made. These results can, however, be seen as a significant success, because in education it is very difficult to obtain some spectacular improvements in such a short time and the most important aim of our project was to help those pupils to remain in the formal learning system so that that the positive conditions were created for their personal development. Key words: formal learning system, prevention, school dropout, school performance.

Strategy for soil protection in cross-border region of Hungary and Romania

Within the Hungary-Romania Cross-Border Co-operation Programme for 2007-2013 the University of Debrecen and the University of Oradea is to elaborate a soil strategy for the Nyírség and Bihor Mts region. Project partners expect the strategy will support and strenghten national, regional and local soil policies and contribute to the competitiveness of the region by protecting and developing various soil functions. Project partners also expect to prevent cross-border problems with soil and reduce the competition caused by cost differences.The elaboration of the strategy includes the problems of erosion, deflation, compaction, water-deficiency, inland water-threat, problems induced by the usage of fertilizers, loss and substitution of soil organic matter, amelioration (bentonite, sewage sludge, fermented biogas). Based on summarised data of former examinations and new experiments a concise database will make it possible to calculate and apply the Sustainability Index Model, which may be useful in order to address EU supports properly based on objective calculations, and may be useful to determine the optimal culture. The project also encourages the farmers to keep in mind the cross-compliance, since EU gives financial support to realise sustainable soil strategy based on EU directives. This may enhance the options to initiate the take off of rural areas with shrinking export facilities, to mitigate social tensions and the effect of migration processes.
