Abstract. The Faculty of Electrical Engineering is partner in the Structural Joint European Project 12132-97 entitled INCOT - New Course Information and Communication Technologies whose major aim is to set up a new Degree course, at the graduate level, in 'Integrated Information and Communication Technology Engineering. The article presents a review of the specific achievements in restructuring the faculty curricula, equipment purchase, development of didactic material, as well as the impact of newly born ideas, their continuity and the dissemination of the project’s results.

1. Overall Project Outputs
As partner in the project, the Faculty of Electrical Engineering expects the following main achievements:

•  development of the curriculum for a new second cycle degree course in "Integrated Information and Communication Technologies";
•  purchase of new equipment including development of multimedia production facilities;
•  short intensive courses held by  EU professors;
•  setting up the MLC inter-network by a permanent interconnection via RoEduNet;
•  setting up an Advisory Council which should include members from enterprises and other local bodies willing to meet biannually.

The overall strategy of our institution includes, among other things, some objectives that can be related to this project: a new second cycle degree course in "Integrated Information and Communication Technologies", the introduction of the European Credits Transfer System (ECTS), the launching of a distance learning package and curricula correlation.
From this point of view, the project is very important to us and the staff mobilities were closely related to these objectives.
To "internationalise" our higher educational system, studies and analyses were made with our partners and the conclusions were analyzed by the Academic Council of the Faculty.

2. Specific Achievements

Creation of a New Degree Course

Appointed members of our Department and the Advisory Council have already elaborated the Curriculum for the new second cycle degree course in "Integrated Information and Communication Technologies". Consequently, we expect our applicants to be in the fortunate position of enrolling for a new specialisation at the end 2001/2002 academic year.

A Multimedia Learning Center (MLC) was set up to ensure access for the targeted staff to the latest technological aspects in the field. This Center will be expanded in the next years.
 

Equipment

Purchased equipment: PC multimedia stations based, network equipment (one fast Ethernet switch, 100 Mbps HUBs, Ethernet Boards) and teaching gadgets (overhead projector, whiteboard). This kind of equipment assures the main technical support for the development of future applications in our laboratories. They match our expectations.
The equipment was installed in the Multimedia Learning Center (75 square meters), located on the second floor of our faculty’s new building.
The equipment is part of a didactic laboratory with scheduled access of both students (class hours and individual work) and the teaching staff involved in ICT and ODL. Moreover, when the short courses in the continuing education network programme begin, this facility will be largely employed by our company applicants.

Curriculum Development

The experience gained within this project led to the introduction of a new direction in the  professional training and management for the 1997/1998-ICT academic year, which, in fact ,starts from the fourth year of studies. We have  consequently developed new syllabi for new disciplines. These developments match our expectations and manage to meet both quality and scope requirements at European levels. We have also made some  changes in the 1st  year postgraduate curriculum. Some minor or even major changes are possible after two or three experimental years of activity based on university-industry interaction.
 Both the new and the reshaped courses are part of the official "Educational Plan" for the Computer Engineering curriculum and the 1st  year postgraduate programme at all levels (faculty, university, ministry). We appreciate  that the initiative is a success in spite of our   limited academic and institutional support.
 The addressability of  these developments is twofold: the teaching staff involved in educational activities and the students of our faculty. We expect to attract 25 to 50 students for the 5-year graduate program and 10 electrical engineers for the postgraduate program (Master Program).
For the moment, this new course is to be delivered only in Romanian, but our academic staff is prepared to deliver it in either English or French, if there should be any international demands.
Didactic materials
Our faculty will benefit of the teaching materials introduced by the academic staff participating at mobilities, such us courses, practical guides, curricula of similar EU graduate programs These materials have already been  translated, adapted and developed in consultation with our EU partners. The printing process was delayed for the second year to ensure a proper ‘polishing’ of the manuscripts.
 

Staff training

The staff training and updating was made on the base of the retraining plan of the faculty. The project is an important component for our faculty and our human resources development plan has been constantly correlated  with the financial support that we can obtain. The information sources permit the running of nigh education program according to the requirements of European education. (??????)
The quality of training provided so far has  met all our expectations, especially  in terms of  information gathering, exchange of ideas and expertise with the our EU partners.  From this point of view, we consider that our constant reference to the European higher education standards is a sine-qua-non condition for the integration of the Romanian University system in  the European one. Special thanks have to be attributed to our EU partners, University of Limerick (IRL), Technological Education Institute of Piraeus (GR) and University of Lund (SE) for supporting our grantees.

3. University/Industry Links

We are targeting enterprises in the fields of communication services, informatics, distribution and transport of electrical energy, machine-tools industry, multimedia, software and hardware ICT technique and any other enterprises ready to employ electrical engineers. We can provide training and updating programmes for their staff  at the highest European standards.
 We have  had a good collaboration with  the technical staff of these companies while developing the new the new  course and the Advisory Council came up with brilliant suggestions for the new ICT curriculum.
Besides retraining, we can provide services related to computer network operations (testing, analyse of traffic, failure points etc.), consulting in industrial projects, or design of new industrial specific applications.

4. Impact

The key success of this project for our institution consists in the following improvements of our curriculum, the internationalisation of courses, the updating and retraining of the academic staff, the penetration of European spirit among the academic staff and the preparation of good conditions for ECTS.
We consider that such projects are important parts of the reform of the educational system in our country. Our disappointments are related to the limited budget of this program, dwelling the possibilities for covering all mobility demands. However, as a whole, it did have a positive impact on our institution.
Our involvement in the project led to the benefits of a positive scientific and educational co-operation between our university and other partners universities (UU, TIP, ULU, FHR) and national and European enterprises. The results obtained by our grantees in each and every  host university were very good and we consider that this fact considerably improves the capability of our university to show its innovative potential in  well–organized and supportive network of creative and productive bodies. We should not forget to mention the three meetings at the PMG level which represented a ‘good school’ for management skills improvement.

5. Continuity and Dissemination

In the future we plan to exploit the achievements of the project by means of  allowing our  teaching staff to impart their newly acquired knowledge  and make their books and   articles internationally available.
The plans for future financing schemes are related to the financial possibilities of the Romanian Ministry of National Education and the short intensive courses given in our MLCs for company managers.
We strongly believe that this project is only the tip of the iceberg in the future extensive institutional co-operation among all our partners.

Summary. The present work presents a typical application of the circuits with switched capacities: the measuring of the low capacities through bridge methods. In the case of the capacitive transducers, where the variation of the output quantity is very low, the measuring bridge - in which the sensor is introduced - implies a high frequency supplying and the use of a very high value resistors. A solution for the rising of the signal/noise coefficient from the measuring bridge with switched capacities. In addition to the design solution of the capacitive transducer and the exhibit of calculation relations, this work also included a series of characteristics which underline the results obtained in practice, when using the available solution.
Key words: switched capacity, measuring bridges, capacitate transducer, error.
