Abstract In the work we have developed a system to record two-layer soil structure by calculating the mesh voltage Em. We have used the computational procedure of the standard IEEE 80-000. We have used the formula for homogeneous structure soil with horizontal stratified medium. We have also used a formulae of equivalent resistivity. We have arrived at the Em values based...

Abstract The reliability and accurate values of measurements is possible now due to the use of electronic precision and sophisticated equipment. We can consider the magnetic fields which is a major input parameter and we can produce new kinds of sensors and measures. The accurate value of the measurement signals is possible based on computers and systems which collect data. We... Read More

Abstract We have designed a new brake system that use the electromagnetic fields. We have used the control and drives available at a particular lab. For electric motors the created brake is highly adjustable and flexible. We have described the procedures and construction methods. We have identified important electromechanical indicators. We have demonstrated the system and use it for control load... Read More
