To introduce this issue, the main objectives of the so-called Green Deal, to which the Czech Republic has committed itself, are outlined, the current energy situation in the Czech Republic is described, including the current extraction of some energy raw materials and the current limits of the main pollutants for large stationary energy sources. Subsequently, this thesis deals with the different types of alternative fuels, the possibilities of their reprocessing and the basic types of solid fuel boilers are listed and described, while their suitability for the use of these fuels is assessed. The thesis concludes with the possible negative impacts of alternative fuels on the operation of combustion plants and finally, the energy sector options in relation to these fuels are summarised. These options are evaluated both in terms of available technologies and the quantity and availability of these fuels for their use in the Czech Republic.361 - Katedra energetikyvýborn

Compressed Pattern Matching

Tato bakalářská práce se zabývá vyhledáváním vzorků v datech. Hlavním úkolem je popsat vybrané algoritmy a datové struktury, pomocí kterých se takové vyhledávání v praxi provádí a to v datech nekomprimovaných i komprimovaných. Nedílnou součástí tohoto úkolu je i implementace vybrané datové struktury. V současnosti se hojně používají komprimační algoritmy využívající Burrows-Wheelerovu transformaci, na které závisí datová struktura FM-Indexu, kterou budeme implementovat. Implementace je provedena v programovacím jazyce C#. Nad výslednou datovou strukturou budou provedeny experimenty, které se zaměří na rychlost vyhledávání a prostorové nároky. Rychlost vyhledávání bude porovnána oproti klasickým algoritmům. Prostorové nároky budou porovnány podle formátu vstupních dat a při různých konfiguracích FM-Indexu. Na závěr jsou prezentovány výsledky a zjištěné poznatky z experimentů implementované datové struktury.This Bachelor's thesis is about pattern matching. Main objective is to describe selected algorithms and data structures, that are used in practice for pattern matching on non-compressed as well as compressed data. Integral part of this thesis is subsequent implementation of the selected data structure. At present, compression algorithms using Burrows-Wheeler transformation are used extensively and data structure FM-Index depends on it. This data structure will be implemented in programming language C# and subjected to experiments. Experiments will mainly cover speed of pattern matching and will be cross examined against more classical algorithms. Space requirements will be tested on data of varying formats as well as with different configurations of FM-Index. At the end the results and findings from the experiments will be presented.460 - Katedra informatikyvelmi dobř

Possible charge ordering and anomalous transport in graphene/graphene quantum dot heterostructure

[Abstract] Observations of superconductivity and charge density waves (CDW) in graphene have been elusive thus far due to weak electron–phonon coupling (EPC) interactions. Here, we report a unique observation of anomalous transport and multiple charge ordering phases at high temperatures (T1 ∼ 213K, T2 ∼ 325K) in a 0D−2D van der Waals (vdW) heterostructure comprising of single layer graphene (SLG) and functionalized (amine) graphene quantum dots (GQD). The presence of functionalized GQD contributed to charge transfer with shifting of the Dirac point ∼ 0.05 eV above the Fermi level (ab initio simulations) and carrier density n ∼ −0.3 × 1012 cm−2 confirming p-doping in SLG and two-fold increase in EPC interaction was achieved. Moreover, we elucidate the interplay between electron–electron and electron–phonon interactions to substantiate high temperature EPC driven charge ordering in the heterostructure through analyses of magnetotransport and weak anti-localization (WAL) ramework. Our results provide impetus to investigate strongly correlated phenomena such as CDW and superconducting phase transitions in novel graphene based heterostructures.R R would like to acknowledge funding by European Regional Development Fund-Project 'MSCAfellow2@MUNI' (No. CZ.02.2.69/0.0/0.0/18070/0009846).

Neuronavigation in therapy and rehabilitationof schizophrenia using rTMS

Transcranial Magnetic Stimulation is a promising therapeutic method which allows non-invasive reduction of schizophrenia symptoms. The main imperfection of this technique had been the impossibility of precise targeting of the rTMS coil at the given cortical area. This can be achieved by using neuroimaging techniques and stereotactic neuronavigation, which enables to target the coil with a high degree of anatomic accuracy. The aim of the study was to investigate the relationship between excitability of motor and visual cortex. Using neuronavigated single-pulse (SP) and paired-pulse (PP) transcranial magnetic stimulation (TMS, Magstim Rapid) over right visual cortex, the phosphene thresholds were measured in 11 subjects. Motor threshold (MT) was identified by using standard methodology. In all subjects the phosphenes were induced by both SP (median = 48 %, IQR = 44,5-52,0) and PP (median = 44 %, IQR=39,5- 48,0) TMS. PP phosphene thresholds were lower than SP thresholds (U = 28,0, p ≤ 0,05). We found the positive correlation between MT and SP phosphene threshold (r = 0,597, p ≤ 0,05) but not for MT and PP. The distance of coil position from the brain surface did not correlate with MT, SP nor PP phosphene threshold. Our findings confirm the relationship between MT and phosphene threshold measured by the use of..
