This article analyses the existing methods both practically and theoretically used to detect defected surface area in solar cells. Various methods were used but by using an upgraded camera with CMOS sensor for carrying out the electroluminescence method, this has proven to have a&#...

This paper shortly introduces the problematic about SCR technology. This research deals with the SCR system which is electrically independent on the goal application. The paper shows results of the system installed into the test vehicle. The laboratory and real-traffic test are discussed.

The presented paper deals with the various possibilities of insulating gases designed as an insulating blend for high voltage distributional switchgear and equipment. The technical superiority of sulfur-hexafluoride is discussed with its environmental disadvantages and limitations. Alternative gases as...

This article deals with reliability and safety assessment of the systems using highly structured systematic analysis FMEA (Failure Mode and Effect Analysis). The FMEA is one of the most commonly used qualitative methods of reliability analysis. This method is often perceived as a t...

A novel concept of modular electromagnetic actuator in valve operation is proposed. The actuator takes advantage of permanent magnets for assuring stable positions of the valve body and field coils for control of the valve operation. Modular design of the actuator allows&#x...

Presented research and development covers robotic system based on magnetically guided actuation of ferromagnetic bodies on planar surfaces. The major goal of this paper is to present selected results achieved on current laboratory prototypes and outline the directions of future ...

The purpose of the paper is to describe the measurement system for various types of air-conditioning diffusers. On the basis of the measurements made, suggest some technical adjustments of the system, which would lead to a more precise measurement and to a leveling of the ...

This paper deals with possibilities of using the loudspeaker for room acoustic. The experiment with large low resonant frequency loudspeaker was done. At first, the vibration of membrane was scanned by using a laser vibrometer for different operating states. The effect on reverbereation...

This paper is focused on comparison and testing of two different microsystems for an inertial navigation intended especially for places without GPS signal. These inertial navigation systems were compared with GPS system. The next research work was focused on dispersion detection from th...
