The nature of the truncation lies in the fact that in the present we ... -
Distributed job execution in IVIS Framework
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2023)Datum obhajoby: 7. 9. 2023This thesis tackles computation distribution in the IVIS data processing and visualization framework. In the existing versions, so-called Jobs are be- ing executed only on the IVIS host machine, raising scalability concerns. ... -
Vybrané aplikácie rekurentnej metódy najmenších štvorcov
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2023)Datum obhajoby: 8. 9. 2023This bachelor's thesis introduces, derives and implements recursive least squares me- thod. The recursive least squares method is analogy to ordinary least squares for linear regression exercise. Method uses recursive ... -

The first chapter consists of the basic concepts and properties of the nor- mal distribution. In the second chapter ... -
Optimization Decision Analysis for Graal
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2023)Datum obhajoby: 6. 9. 2023Modern compilers apply a set of optimization passes aiming to speed up the generated code. The combined effect of individual optimizations is often un- predictable. Thus, changes to a compiler's code may hinder the performance ... -
