An electronic nose for quantitative determination of gas concentrations
PublicationThe practical application of human nose for fragrance recognition is severely limited by the fact that our sense of smell is subjective and gets tired easily. Consequen tly, there is considerable need for an instrument that can be a substitution of the human sense of smell. Electronic nose devices from the mid 1980s are used in growing number of applications. They comprise an array of several electrochemical gas sensors...

Power Electronic Transformer For Smart Grid Application
PublicationIn this paper the control system of Power Electronic Transformer (PET) for the Smart Grid application is proposed. The structure of PET is based on two Cascaded H-bridge (CHB) converters. The electrical energy is transferred between converters using Dual-Active-Bridges (DAB) and high-frequency transformers. This type of coupling has been used to connect the DC-links of all H-bridges. The proposed control system for PET makes it...

CM Voltage Compensators for Power Electronic Interfaces
PublicationThe experimental results presented in the paper have shown that the application of the PEIs might cause EMC related problems, especially in the case of the application of a group of connected converters. The most convenient way to reduce EMI currents and prevent aggregation of EMI currents introduced by a group of converters is through passive compensation of voltage interference sources inside of the single converters. In the...

On the electronic structure of methyl butyrate and methyl valerate
PublicationWe present novel results of the analysis of the electronic structure of two aliphatic esters: methyl butyrate and methyl valerate. High-resolution photoabsorption spectra were collected and analyzed over the energy range 4.0–10.8 eV and showed for both the molecules not only a clear band of the HOMO to LUMO transition, but also vibronic structure associated with the first Rydberg-valence transition. Photoelectron spectra recorded...

Nałęczów tonie w gęstwinie
PublicationBudynki, ulice, wzniesienia i jary Nałęczowa zanurzone są w gęstwienie drzew, które o każdej porze roku otulają i szczelnie zamykają miasto. Trzeba zapomnieć miejsce kilkuletniego pobytu, by ujrzeć je na nowo. Wówczas długi, wąski korytarz szkoły plastycznej i jego rozgałęzienia naturalnie łączą się z tkanką okolicy. Po latach widzi się tę przestrzeń jako wąską szczelinę albo rodzaj ucha igielnego, przez które trzeba było przejść...
