VĂœhodou ĆadicĂch sĂtĂ je snadnĂĄ implementovatelnost do hardware, ale jejich nĂĄvrh je velmi sloĆŸitĂœ.

Sorting networks are abstract models capable of sorting lists of numbers. Advantage of sorting networks is that they are easily implemented in hardware, but their design is very complex. One of the unconventional and effective ways to design sorting networks is Cartesian Genetic Programming (CGP). CGP is one of evolutionary algorithms that are inspired by Darwinian theory of evolution. Efficiency of the CGP algorithm can be increased by using coevolution. Coevolution is an approach that works with multiple populations, which are influencing one another and  constantly evolving, thus prevent the local optima deadlock. In this work it is shown, that with the use of coevolution, it is possible to achieve nearly twice the acceleration compared to evolutionary design.
A Comparative Analysis of Text and Music and Gender and Audience in Duke Bluebeard\u27s Castle
Andrea FĂĄbry discusses in her article, A Comparative Analysis of Text and Music and Gender and Audience in Duke Bluebeard\u27s Castle, the image of Bluebeard as a metaphor for gender relations. BĂ©la BartĂłk\u27s opera and its libretto represent a prime example of the metaphor that in turn can be found in a range of text types, from fairy tales through novels to films. In the article, FĂĄbry analyzes BartĂłk\u27s contribution to the metaphor, namely with his opera, Duke Bluebeard\u27s Castle. She relates the opera to the text of the opera\u27s libretto, written by film theoretician BĂ©la BalĂĄzs, and places her analysis in the larger historical framework of audience research in modernity. The analysis reveals that in a pronounced misogynistic artistic climate of the time and working from a libretto whose tragic ending denies transcendence to the female character of the opera, BartĂłk\u27s opera can be understood as the representation of simplistic domesticity where the real story remains un-mediated and un-narrated
N-[Amino(imino)methyl]uronium tetrafluoroborate
In the title compound, C2H7N4O+·BF4
â, interÂmolecular NâHâŻO hydrogen bonds connect the cations into chains parallel to the c axis, with graph-set motif C(4). These chains are in turn connected into a three-dimensional network by interÂmolecular NâHâŻF hydrogen bonds. The BâF distances distances in the anion are not equal

The first part is devoted to the locality description, ascertained problems, the video analysis and the evaluation of conflict situations obtained from the road transport - engineering survey. The road transport - engineering survey was used to determine the intensity, the structure of traffic flows and conflict situations. The second part of the thesis focuses on the proposal to improve the traffic flow and safety and looks into capacity calculations. This section includes a landscaping of the current state of the crossroads in two variants. In the last part there are simulation models of the crossroads in the program PTV VISSIM.227 - Katedra dopravnĂho stavitelstvĂvĂœborn
2,4-DimethylÂanilinium perchlorate
The crystal packing of the title compound, C8H12N+·ClO4
â, is stabilized by NâHâŻO hydrogen bonds, the protonated amine group acting as a hydrogen-bond donor with the perchlorate O atoms as acceptors. These connect neighbouring cations and anions, forming a two-dimensional network. Variable-temperature dielectric constant measurements on the salt indicated that no distinct phase transition occurred within the measured temperature range of 80â293â
