From the medieval age university quality has been widely known by writings of students, great names of professors and communiqués of politicians at universities. But since the last quarter of the twentieth century three most influential and widely observed international university rankings qualify and update world's universities annually. The paper presents all three ranking systems in a new structure,...
The rapid growth of fast and reliable communication networks provides an easy exchange of information and commands between computers connected to sites of wide area networks such as the internet. Engineers from far away workstations can operate various remote equipment through the internet. Engineering is transformed into a constructive joint effort within the framework of simulation and exploration...
Science and technology will improve the quality of life of future generations. A knowledge-driven economy goes along with high-tech companies. University of Miskolc has information about industry products, marketing and development trends, feedback on graduates' competences, the quality of teaching, improves curriculum, teaching materials and methods, implements its research mission successfully by...
The world wide web became a vital element of all human activities by now. The rapid growth of fast and reliable communication networks provides an easy exchange of information and commands between computers connected to sites of wide area networks such as the internet. Engineers/students form far away workstations can operate through the internet with various remote equipment, since integrated web-learning...
Rational use of electricity can be carried out by better design, precise manufacture, energy save operation of electrical consumers while minimizing the failures, thus improving reliability and availability. Electricity cost of a high power consumer during its life span exceeds 25 to 50-times the total cost, thus computerised electricity management by the contribution of the Department staff can save...
A fractional-horsepower dc motor test series performed in a remote controlled virtual laboratory by Internet access was developed. Nowadays the remote controlled industrial systems have got great importance worldwide. The internet access has become general and the Ethernet cabling has been entirely applied in industry. The new virtual laboratory introduces users into the application of the most sophisticated...
The world market of motor-driven home labor-saving devices such as kitchen robots, washing machines, dryers, refrigerators, deep freezers, washing-up machines and many others exceeds 150 billion Euros and the growth rate is 1.5% per annum. Around 45% of engineers work within design, production and research fields, thus a new smart measuring instrument for motor-driven domestic labor-saving devices...
The earth has become 0.76degC warmer since the industrialization took up high speed. To reduce the global rise in temperature by the critical 2.00degC requires that the content of greenhouse gases in the atmosphere will be limited to 450 (plusmn50) particles per million over the long term. In 2002 the total emission was 40 billion tons (Gt) and by 2030 it will be 58 Gt if nothing will be done. To...
High-tech drive control needs high quality of electrical energy like safe, continuous voltage supply with the required current at constant rms values and at constant frequency, then pure sinusoid waveform of voltage. If the rated voltage impressed to the computers in control systems will be decreasing to its 75% the disturbance in their operation appears and at 50% they all will loose their ability...
The end-consumers need high quality of electrical energy like safe, continuous voltage supply with the required current at constant rms values and at constant frequency, then pure sinusoid waveform of voltage. If the rated voltage of computers will be dropping down to its 75% the disturbance in their operation appears and at 50% they will loose their ability for work, then the acquired data, the envisaged...
In 2005 electricity generation from renewable energy sources in Hungary was 1721.7 gigawatthour (GWh) which was 4.5% of the total consumption while in the previous year this ratio was only 2.3% i.e. 884 GWh. By the end of 2005 Hungary exceeded the envisaged 3.6%, which will be increased to 7% by 2010. The authors were active members of individual, industry-academia projects in the clean power field...
Human beings just entered the globalization age, sustainable development and knowledge-based society are knocking at the door. Industry-academia link provides a good chance to be active players in the European Research Area. One example is the continuous casting where heavy and burning liquid steel is pouring out from a vessel traveling together with the crane and driven by induction motors. The motors...
