Translation of PHP Language Subset into C++
Nechutný, Stanislav ; Matula, Peter (referee) ; Křivka, Zbyněk (advisor)
My work is focused on design and execution of an automated translation for functions written in PHP into C++. Generated code may be compiled as a PHP extension and loaded the same way MySQL, PDO, GD or so. As a result these functions may be called from PHP as if they were the initial interpreted functions. Since there is no need for source code analysis, interpretation, nor staging by Garbage Collector general assumption would be a significant speed difference. Created tool executes source code transfer into abstract syntactic tree which is followed up by a static analysis of variable types and consequently generates C++ code. Final speed increase then depends on the particular code being translated and its practical use is slightly elaborate at the moment - owing to the implementation of PHP subset.

Surface states in photonic crystals
Vojtíšek, Petr ; Richter, I.
Among many unusual and interesting physical properties of photonic crystals (PhC), in recent years, the propagation of surface electromagnetic waves along dielectric PhC boundaries have attracted considerable attention, also in connection to their possible applications. Such surfaces states, produced with the help of specialized defects on PhC boundaries, similarly to surfaces plasmons, are localized surfaces waves and, as such, can be used in various sensing applications. In this contribution, we present our recent studies on numerical modelling of surface states (SS) for all three cases of PhC dimensionality. Simulations of these states were carried out by the use of plane wave expansion (PWE) method via the MIT MPB package.
