Kolář's mea culpa
Boháč, Petr ; Šrámek, Petr (advisor) ; Brabec, Jiří (referee)
Umělecké dílo je možné nahlédnout z několika perspektiva vždy se ukáže jako jiné a zároveň v jinakosti jako podobné. V této nevyjasněnosti - neklidu - vězí krása díla. A přesto každý interpret, sám za sebe i navzdory dílu samotnému, se musí pokusit najít onen kruciální bod, ze kterého bude dílo nahlíženo. Není důležité, dopracuje-li se k tomuto bodu až postupem čtení, až v samotném rozkrývání jednotlivých složek, nebo jestli díky němu do něj vstupuje, aby jej na konci popřel nebo potvrdil. Slouží mu jako kompas při zbloudění i jako ta část mapy, do níž ještě není zanesena krajina, ta bílá místa, která vábí interpreta k doplnění. V této práci se tímto bodem stane skutečná událost, chápaná ve vztahu k básnické řeči, k realitě, k básníku, jenž nahlíží sebe sama i druhého - ve vztahu ke světu, v němž básník žije, do něhož se projektuje, s kterým se vyrovnává, pro který píše, ale i ke světu jakožto unikátnosti básnické řeči, v níž skutečnost mizí. Nahlížení přes optiku skutečné události vyvrcholí v básni Skutečná událost ze sbírky Prométheova játra, jako v ní vrcholí i básnická tvorba Jiřího Koláře.

Parallel Implementation of Multireference Coupled Clusters Methods and Calculations on Large Systems
Brabec, Jiří ; Pittner, Jiří (advisor) ; Fišer, Jiří (referee) ; Pitoňák, Michal (referee)
Firstly, we have developed a Tensor Contraction Engine-based implementation of the BW-MRCCSD approach. The scalability tests have been performed across thousand of cores. We have further developed a novel two-level parallel algorithm for Hilbert-space MRCC methods which uses the processor groups. In this approach, references are distributed among processor groups (reference-level parallelism) and tasks of each reference are distributed inside of a given processor group (task-level parallelism). We have shown that our implementation scales across 24000 cores. The usability of our code was demonstrated on larger systems (dodecane, polycarbenes and naphthyne isomers). Finally, we present novel universal state- selective (USS) corrections to the state-specific MRCC methods. The USS-corrected MRCC results were compared with the full configuration interaction (FCI) results.

History and narration. Palacký's "Dějiny" as a source of historical imagination of nation
Činátl, Kamil ; Šmahelová, Hana (advisor) ; Brabec, Jiří (referee) ; Vašíček, Zdeněk (referee)
This doctoral thesis mainly focuses on the narration of history and its culture creating potential - that is to say, its ability to form imagined communities. Primarily, it deals with the grand historiographic syntheses of national history (Michelet, Palacký, Lelewel etc.) emerging mainly in the 19th century, in which an important part was not played only by enlightenment criticism ad heuristics, but also by the traditional imaginative power of narrative. In the thesis this model of a "new" national historiography is particularly represented by Palacký's Dějiny národu českého v Čechách a na Moravě (The History of the Czech Nation in Bohemia and Moravia). The detailed narratological analysis of this work, which in many respects was the founding text of the modern Czech historical consciousness, attempts to illuminate to which extent the modern idea of nation was constituted by the historical imagination. Therefore, the analysis does not concentrate only on Palacký's The History, but also on the adjoining "gravitation field" of both historiographic and artistic representations of national history. The narratological point of view is employed also in the analysis of the mutual relations between historiographic narrative and historical fiction (historical novel). In many regards, the obscurity of the...

The captain of his generation? Zdenek Kalista and the Young Czech Literature in 1919 - 1924
Malínek, Vojtěch ; Wiendl, Jan (advisor) ; Vojvodík, Josef (referee) ; Brabec, Jiří (referee)
The aim of this thesis is to present the literary activities of Zdenek Kalista in 1919- 1924, a period which saw him becoming one of the most prominent figures of the young post- war generation of writers. The research has been primarily based on materials that had been so far ignored or insufficiently reflected (literary remains of Zdenek Kalista, Antonin Matej Pisa, Cestmir Jerabek, Lev Blatny, Jiri Wolker etc., as well as articles from contemporary magazines and daily newspapers) together with Kalista's memoirs. The thesis is divided into five chronologically sorted parts, each reflecting one year of Kalista's life and work and relating them to the literary situation of that time, while continuously describing them from multiple perspectives. In the first part, Kalista's personal life and the activities of the youngest literary generation are analyzed. After that, the focus shifts to the contemporary art groups (Umelecky klub, Literarni skupina, partly Devetsil) and Kalista's relationship with his contemporaries and various key figures of the literary scene (Jiri Wolker, Antonin Matej Pisa, Frantisek Gotz, Stanislav Kostka Neumann etc.). Then, Kalista's activities in the respective years are analyzed, be it for his work in contemporary magazines (Den, Orfeus, Host), his books (collections of...

The Singlet-Triplet Gap in Trimethylenmethane and the Ring-Opening of Methylenecyclopropane: A Multireference Brillouin-Wigner Coupled Cluster Study
Brabec, Jiří
The Singlet−Triplet Gap in Trimethylenmethane and the Ring-Opening of Methylenecyclopropane: A Multireference Brillouin−Wigner Coupled Cluster Study Abstract We performed an ab initio study of the singlet−triplet gap in trimethylenmethane (TMM) and of the ring- opening of methylenecyclopropane by the multireference BWCC method. Since the singlet states of TMM and intermediates between TMM and methylenecyclopropane have a strong multiconfigurational character, it is necessary to use a multireference method. The cc-pVDZ and cc-pVTZ basis sets were used. We compared our results with experiments, where available, and with previous calculations performed by MCSCF and spin-flip coupled-cluster-type methods.

Functional changes of Vltava riverbanks in Prague
Brabec, Jiří ; Fialová, Dana (advisor) ; Šantrůčková, Markéta (referee)
This diploma thesis deals with the functional changes of the banks of the Vltava river in the territory of today's Capital City of Prague. There have been significant changes in the functional use of this area due to large interventions in the bank line and the redevelopment of the embankment. During last 150 years changes are closely monitored. Changes were also made conditional on connecting nearby rural communities to Prague. Theoretical bases are the concepts of shore-side changes in urbanized areas, complemented by examples from the world that serve as a comparative study. Furthermore, the thesis is based on the theory of photography and the iconographic approach, which are essential for this work. The methodology of the thesis is based on the analysis of historical and contemporary photographs and information, on field research and vectorization of historical maps, where the course of the flow is monitored in four time periods (the mid-19th century until present). The work captures functional changes of banks in text form, as images and fundamental changes in tables. Part of the work is also a web application, where the changes in cartographic, picture and text form are again accessible to the public. Key words Vltava river, Prague, riverbank, waterfront
