Tiliting modules of finite type
Šaroch, Jan ; Žemlička, Jan (referee) ; Trlifaj, Jan (advisor)
The thesis studies properties of cotorsion pairs in the category of modules; we are mostly interested in conditions under which the given cotorsion pair is complete or, actually, of finite type. Methods of deconstruction of cotorsion pairs developed during our inquiry are eventually used to prove that every tilting module is of finite type. We show also a connection of presented problems with so-called telescope conjecture.

The methodology for visualization of the internal structure of the painting using novel x-ray based methods
Hradilová, Janka ; Hradil, David ; Trmalová, Olga ; Žemlička, Jan
Aim of the methodology is to involve the newly tested a newly developed methods, which allow displaying an internal structure of a painting, into the routine conservation/restoration research. The methodology is yet specifically focused only on methods using X-rays, i.e. X-ray radiography (XRR) and X-ray fluorescence (XRF) (including macroscopic XRF scanning). The methodology includes testing the radiographic equipment with pixel detectors, which has been newly developed within the project, and assesses its contribution to the practical survey of painting techniques reflecting its exceptional spatial resolution, materials sensitivity and mobility.

Moderní informační infrastruktura organizace - na konkrétním případě
Žemlička, Jan ; Kubešová, Vlasta (advisor) ; Slabý, Jiří (referee)
Diplomová práce se zabývá problematikovu budování informační infrastruktury organizace. V první, teoretické, části se zabývá obecně pojmem informace, jejími atributy, významem a účelem, který přestavuje pro současné podniky jeden z klíčových faktorů úspěchu. V druhé, praktické, části naznačuje na konkrétním případě možnosti budování informační infrastruktury na platformě produktů společnosti SAP, s ohledem na organizační a uživatelské požadavky.
