Measurement of Friction Losses of Electro-Pneumatical Valves with Industrial Devices
68-72Views:86The pneumatic devices are frequently used in several fields of the industry but the losses and pressure
drops of the pneumatic system are not really investigated. These losses can cause great property damages during long uptime because the compressed air is a quite expensive energy source. I designed a measuring system which is able to measure the friction losses of electro-pneumatic 5/2-way valves (monostable and bistable too). It is possible to choose between manual and automatic operation modes as well. In the automatic mode the system makes measurements in three different user-defined pressure levels. In the manual mode the measuring pressure can be set between 2-6 bars. An automatic evaluate program is also an important part of the created system. It gives the possibility of the fast evaluation of the saved data and it could be the base of a fast report generating application. -

Simulation of BLDC Motor Drive Systems for Electric Vehicles Using Matlab Simulink
48-52Views:211The defining scientific developments of our time would not have been possible without the use of simulations. The aim of the research is to create a simulation of a BLDC motor. When creating a simulation, great emphasis must be placed on defining the purpose of the simulation. This basically determines the structure and complexity of the model. The model discussed here was created so that an optimization task could be defined more precisely by inserting it as a sub-model into a vehicle dynamics model. Scalability was another aspect, that is, to be able to increase the accuracy of the model with measured data in the future, as well as to be able to validate it. During the research, a BLDC motor efficiency map generation program was created, as well as an environment for testing the generated data. The created system gives researchers the opportunity to use a shape-correct efficiency model when simulating a BLDC motor even without measured data. This makes it possible to discover real relationships between model parameters when performing optimization.

How Does Public Debt Change when the Next Crisis Comes - and It Will Come!/the Expected Evolution of Greece's State Debt in the Next Crisis Period/
91-104Views:228It has recently been announced that Greece may withdraw from the Euro-Zone permanent rescue fund's aid program because it has successfully met the conditions imposed on it. Creditors and credit qualifiers also agreed that the Greek economy was on a good growth path. That is why there is a chance that by 2030 the current sovereign gross debt of 182.7 per cent of GDP will fall to 123.3 per cent. The author finds this statement unfoundedly optimistic. He argues that the Greek debt ratio – despite the current optimum economic fundamentals – does not seem to be sustainable. He sees greater probability that in the near future it will again be necessary to release some of the Greek debt. Debt reduction will also mean a new orderly state bankruptcy. The study seeks to highlight how vulnerable and risked the sustainability of current Greek debt financing. Using a macroeconomic model, it shows and justifies how the Greek sovereign debt changes in the case of a crisis that is only half the extent of the previous subprime crisis. If this happens, by 2023, the state debt will rise to more than double the national product, and by 2030 only to the present, otherwise critical, level. It follows that the high risk of financing Greek state debt remains unchanged.
