The reqested voltage value is one of the main indicators of the delivered electric energy quality. The energy transfer system has to secure the good-quality electric energy deliveri for all consumers in the time when the electric energy market is…

This paper introduces application in image analysis of biomedical images. General task is focused on analysis and diagnosis biomedical images obtained from program ImageJ. There are described methods which can be used for images in biomedical application. The main idea…

The paper presents principles and properties of the soft switching PWM DC-DC converters. The attention is focused mainly on high power applications and thus the full-bridge inverters are used in DC-DC converters. Considerations are also given to the control methods…

We briefly review rigorous results on the finite-size effect near first-order phase transitions at which a two-phase coexistence takes place. We consider a large class of statistical mechanical models in (hyper)cubic volumes with periodic boundary conditions at low temperatures. The…

Oxide films long-time grown on tubes of three types of zirconium alloys in water and in steam were investigated, by analysing I-V characteristic measured at constant voltages with various temperatures. Using theoretical concepts of Rose [3] and Gould [5], ZryNbSn(Fe)…

In the present paper we describe a computation of the position of a tectonic dislocation in the shape of a line, which is radiating gamma rays. We derive the equation for dose rate as a function of the distance of…

The phenomena of rhythm fluctuation of arterial blood pressure were discovered already in the first continuous recordings in the 18th century. However the formation of such rhythms hasn’t been explained until now. This work presents two concepts which could aid…

It is increasingly clear that the traditional way of measuring blood pressure in the clinic or office frequently produces numbers that grossly overestimate a patient’s true blood pressure level. This effect is often caused by so called „white coat“ syndrome.…

Distributed modular system BioLab for biophysical examinations enabling assessment of the thyroid gland functional state is presented in the paper. The BioLab system is based on a standard notebook or desktop PC connected to an Ethernet-based network of two smart…

Shortening of RR intervals is often associated with prolonging QT intervals in dynamic studies of the cardiovascular activity in horses. Causes of the relationship have not been explained neither in veterinary nor human medicine yet. Our simulation experiments explain that…
