This paper presents the designing, modeling, and simulation of the spiral circular magnetic field probe for near field measurements. Two configurations of this probe have been investigated using both reference boards – conventional and microstrip. Furthermore, this probe has a compact size&#...

In the framework of the MICADO project we proposed an active long-term nuclear waste monitoring system based on Timepix3 technology. Particle detectors based on Timepix3 are capable of particle type discrimination and provide spectrometric information in combination with precise timing informatio...

This paper describes a fast serial digital signal receiver for applications in nuclear instrumentation. The proposed design uses a Microsemi Polarfire FPGA embedded Ethernet transceiver for data oversampling (with frequency up to 12.7 GHz) and deserialization. The subsequent FPGA implemented digi...

This paper deals with sensors and localization methods suitable for Autonomous Robotic Platform (ARP). Such a platform is used for ADAS (Advanced Driver Assistance Systems) testing in automotive. At the beginning, the paper gives an introduction to the project and then it focuses o...

In some applications the piezoelectric transformers represent an interesting alternative to the conventional transformers with electromagnetic coupling. The piezoelectric transformer output voltage is generated by the piezoelectric effect. This voltage is generated as a result of charge generation. When&#x...

In present time the high efficiency switching DC/DC converters, e.g. buck and boost are often used. This work describes some problems of DC-DC converters, which can occur, when the load is suddenly disconnected or simultaneous disconnection of the load and the capacitor at the...

Placing a machine footing over a small thickness of soil layer, which is located over a bedrock, could encounter many challenges due to the bed’s notable stiffness in comparison to the soil. The advantages of using rubbers to protect facilities (structures, machine foundations, nea...

Nowadays the waste rubber problems are concerned due to the environmental issues, storage, and recycling difficulty. However, the rubber base equipment has been widely used to protect structures for vibrations - that has been generated by the structure or induced from the vicinity ...

In this paper, we investigate a non-invasive procedure for static and dynamic modeling of cardiac output and oxygen consumption in response to cardiopulmonary e...

Cuff pulse waves together with cuff pressure are essential in modern automatic blood pressure (BP) devices. Most methods for BP determination employ cuff wave amplitudes. Physiological features of cuff waves have been neglected. In this study we described &#x...

Digital oscillators are essential parts in many applications. They are used in communications, control, radar, in digital signal processing and music synthesis. Flexibility, and low cost are the main advantages of such type of oscillators. Moreover, he parameters of a digitally generated...

This work describes system for elecrocardiographic (ECG) signal scanning with non-contact electrodes and wireless data transmission. Introductory part deals about electrocardiography and generally with analog signal processing especially with active capacitance electrodes. In the next part of this work...

For an autonomic power lines inspection robot the energy harvesting system and communication systems are being developed. In this paper the energy harvesting based on toroidal split core current transformer is described. The maximal output power is depend on the current in power li...

The home battery energy storage systems (ESSs) are expanding worldwide together with the renewable energy sources (especially solar power plants). As the energy sourced by the different power sources (sun, wind, electrical grid) has to be stored inside the ESS the electrochemical cells&...

This work describes one of the possibilities of amplitude control in recursive sinusoidal digital oscillators with integer arithmetic. As in the case of analog oscillators, it is also necessary to control the amplitude of digital oscillators with a sine wave. If the amplitude is&#x...

In this paper examines procedure for modelling of cardiac output and oxygen consumption as response to cardiopulmonary exercise on a treadmill or bicycle ergometer. The results are presented on 2 athletes - football player and country ski runner which undergone a several stress tes...

This paper compares the different versions of hardware realization of low-cost device for standstill frequency response SSFR testing. The SSFR testing is a modern method used for testing and parameter identification for electrical machines especially for synchronous machines (high power generator...

Long-term usage of photomultiplier tubes (PMTs) led to the discovery of aging effects especially in harsh environment as a radiation is. Aging decreases the efficiency of the PMTs. This means PMTs need to the recalibration after some time. Because CERN´s Large Hadron Collider (LHC)...
