Application of Cross-Section Filtration to Detect and Correct Errors Caused by Technical Problems in SMPS.
Wagner, Zdeněk ; Kovanic, P. ; Zíková, Naděžda ; Ondráček, Jakub ; Schwarz, Jaroslav ; Ždímal, Vladimír
The aim of the work is thus development of a robust algorithm for detection of such errors and their fully automatic correction. The algorithm should be fast so that it could be applied in real time.
Physicochemical Characterization of Chiral Ionic Liquids for Their Applications.
Andresová, Adéla ; Bendová, Magdalena ; Wagner, Zdeněk ; Husson, P. ; Feder-Kubis, J. ; Traïkia, M.
In this work, we address a thermodynamic characterization of a homologous series of 1–[(1R, 2S, 5R)-(–)-menthoxymethyl]-3-alkylimidazolium bis{(trifluoromethyl)sulfonyl} imide ionic liquids. The alkyl chain length ranges from methyl to dodecyl. In this study, our attention is focused on the thermodynamic properties of the pure CILs, i.e. on their heat capacities, densities, viscosities, and self-diffusion coefficients of the cations. The second level is to gain a deeper understanding of the structure-property relationships. Data analysis was carried out by means of mathematical gnostics.
Changes in Sub-micron Number Size Distributions at Czech Rural and Urban Background Stations in the Last Ten Years.
Zíková, Naděžda ; Ondráček, Jakub ; Wagner, Zdeněk ; Ždímal, Vladimír
In this work, not only total concentrations are evaluated, but also particle number size distributions (PNSD) are compared in the last decade at the two stations, and possible explanations for the change in concentrations and PNSD changes are looked for. Additionally, also the change in the frequency and strength of the NPF events is evaluated.\n

Advanced Data Analysis of Thermophysical Properties of Chiral Ionic Liquids with a (1R,2S,5R)-(-)-Menthol Substituent.
Andresová, Adéla ; Bendová, Magdalena ; Schwarz, Jaroslav ; Wagner, Zdeněk
In this work, MG is used in data analysis in a comprehensive physico-chemical characterization of the chiral ionic liquids of a 3-alkyl-1[(1R,2S,5R)-(-)-menthoxymethyl]imidazolium bis(trifluoromrthylsulfonyl)imides homologous series with a linear alkyl substituent ranging from the methyl uo to the dodecil group.

Changes in Sub-micron Number Size Distributions at Czech Rural and Urban Background Stations in the Last Ten Years.
Zíková, Naděžda ; Wagner, Zdeněk ; Ondráček, Jakub ; Ždímal, Vladimír
In the Czech Republic, long-term sub-micron measurement has been set up simultaneously at two background stations, almost ten years ago. The first station is Prague-Suchdol, an urban background station that started in 11/2007, the second is Košetice observatory, a rural background station starting its measurement in 4/2008.

Secure network based on CISCO systems
Wagner, Zdeněk ; Beran, Jan (referee) ; Macho, Tomáš (advisor)
This work deals with the matter of Virtual Private Network (VPN) utilizing both contemporary and older protocols and the possibilities of their use. Among the most interesting parts there are those presenting various ways of use of the VPN technology, IPSec protocol, IOS SSLVPN and RSA server with HW token ensuring the two-factor user authentication.
Advanced Data Analysis for Industrial Applications
Wagner, Zdeněk ; Kovanic, Pavel
One of the principal tasks of nowaday's industry is process intensification. The methodology for finding reliable results is highly demanded. While marketing is concentrated on analysis big data that are available in eShops as well as other internet media, the situation in the industry is different because solution must be found in real time based on limited amount of data. The algorithms of data analysis must therefore be fast and robust. In the last few decades statistical methods have advanced considerably but a new, nonstatistical approach to uncertainty, called mathematical gnostics, have also be developed. This new approach is based upon the fundamental laws of nature and robustness is its inherent property. The contribution will present several applications with the emphasis laid upon description of the main features of mathematical gnostics. Previous applications in energetics that can be enhanced by use of the modern algorithms of data analysis will also be mentioned.
