Kombinatorika

Abych nemusel pořád hledat na internetu, když si zrovna nemůžu vzpomenout na nějaký kombinatorický vzorec, rozhodl jsem se, že si tady napíšu takové malé shrnutí. Většina informací (včetně příkladů) pochází z téhle stránky - je to součást diplomové práce, publikované na webu. Kromě teorie se tam dá najít i spousta příkladů. V případě zájmu o [...]

pyOZ available

First version of my Ornstein-Zernike equation solver written in Python (pyOZ) is released and available for download. It is still a beta, but it proved to be stable enough during thorough testing. You can find out more information on the pyOZ homepage.

New presentations

My presentation from a meeting in Fulda in April 2008 and another one for the workshop “Ion Specific Phenomena in Physics, Chemistry and Biology” which is taking place next week in Garching were added to the Presentations list.
Updated publication lists (PDF Czech, English; LaTeX source .tar.bz2) were uploaded as well.
All related parts of the [...]

I am back…

The vacation is over and it is time to get back to work… Photos from our trip have to be processed first, so it will take some time before they are posted here - stay tuned for updates.
During our travel, another paper of mine was published, this time in the Journal of the American Chemical [...]

pyOZ homepage

I am main and (currently) also the only one developer of an iterative solver of the Ornstein-Zernike equation. The program is called pyOZ and is written in Python programming language with heavy use of the SciPy/NumPy bundle for scientific computing.
The homepage of the project was created under http://pyoz.vrbka.net.

Publications update

Another paper is out (after a very very long waiting period). This publication concerns the theoretical study (by means of DFT) of interactions of acetonitrile with Na-zeolites. The abstract and also full text information are accessible here. Publication records (web, PDF, English, PDF, Czech, LaTeX source .tar.bz2) in this web presentation were updated as well.

Teaching and publications update

The notes for the lab experiment “Binary diagrams from cooling curves” were modified and extended. The text can be found here (at the moment only in English language). German version should follow soon.
Our new publication in Physical Chemistry Chemical Physics concerning cations in zeolites and their interaction with acetonitrile has been added to the publication [...]

Content updates

New publication (research article in the Journal of Physical Chemistry C) has been added to the publication list. Also the general Publications page was modified. This paper discusses the results of a combined experimental and theoretical study of water freezing in the presence/absence of salt ions. The freezing experiments with levitated water droplets were accompanied [...]

Constants, conversions, potentials, …

Some useful data…

Zobrazování vzorců opět funguje

Po delší době opět funguje zobrazování matematických vzorců s využitím syntaxe typografického systému . V souvislosti se změnou způsobu zadávání jsem musel opravit všechny tři dříve publikované texty, které tuto možnost využívají.
Jedná se o
vlastnosti Diracovy delta funkce
vlastní funkce harmonického oscilátoru
vlastní funkce Hamiltoniánu pro angulární moment a degenerace kvantového stavu
Použité řešení by mělo být do budoucna [...]
