Form finding of shell structures
Musil, Jiří ; Bažant, Zdeněk (referee) ; Vítek,, Jan (referee) ; Stráský, Jiří (advisor)
The theme of this doctoral thesis is the design of concrete shell structures with the focus on finding their optimal shape. The optimal shape of a concrete shell is the shape in which for a given load (usually the dead weight of the structure) no significant bending moments are generated in the shell and the structure is in the so-called membrane state. The inspiration for this thesis is the work of Swiss engineer Heinz Isler, who developed the shapes of shell structures using model tests of appropriately loaded flexible membranes. He developed the shell structure for large spans by inverting the resultant shape, which carried its weight almost entirely via membrane forces. The numerical solution of the above experiments using Midas Civil is presented herein. The basic principles of the method are demonstrated on the example of sagged cable. The numerically found shapes are compared with the analytical solution. A shell is designed based on the numerically found shapes and its stress response to dead load is described, particularly in relation to the membrane action. In the next part, the acquired knowledge and methods were used to design three relatively complicated shell structures. Each structure was statically analysed and its static behaviour was described. Structures with perfectly rigid or flexible supports, which simulate real behaviour of the supports, were studied. In the final phase, the results of static analysis of the selected shell were experimentally verified on a physical model in a scale of 1: 55.56. The model has been built using 3D printing. The thesis describes the use of a modelling similarity, the model design, the production process, and the experiment. The load test confirmed the optimal design of the shell structure and the validity of the numerical method for finding their shapes.

Modular Architecture of Distributed Applications
Musil, Jiří ; Hrubý, Martin (referee) ; Hanáček, Petr (advisor)
Traditional architectures of software systems are in heterogenous environment of today's computer networks too heavy-footed. One of principles, which tries to solve this problem is service-oriented architecture (SOA). Practical way of its implementation is represented by web services (WS) built upon protocols like SOAP or XML-RPC. This diploma thesis focuses problem of providing contextual information to mobile devices and its solution based on SOA principles. The thesis introduces design and implementation of web service providing contextual information to mobile devices and prototype of modular inverse SOAP proxy server allowing its effective monitoring and management.

Nuclear power plants
Musil, Jiří ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
This bachelor's thesis deals with history and future of nuclear reactors, it describes nuclear power plants in the Czech Republic and provides a list of promising possibilities of using nuclear energy, that are currently in research. Description of the secondary circuit based on Czech nuclear power plants is also included in this thesis. In the beginning, some elementary knowledge about nuclear energetics is gathered, to provide readers with basics of this topic.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.

Design of concrete structure of Music Pavilion in Podebrady
Juda, Jan ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
This diploma thesis is focused on the roofing of the stage in spa park in Poděbrady. This construction is designed in two variants. In each variant is determined load on the structure and internal forces acting on the structure. Of these two variants, only one variant was selected. This selected variant was design in detail. In this variant was dimension their parts. Under the roof construction is located stage, which was not solved in the diploma thesis. All elements are dimensioned to the ultimate load condition by ČSN EN 1992-1-1. Drawings of the foundations, shapes construction, reinforcement and visualization are processed in the drawing part.

Software for inverse heat transfer problems
Musil, Jiří ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
Tato práce se zabývá vytvořením softwarového nástroje pro simulaci přenosu tepla se zaměřením na využití inverzní úlohy. Je zde popsána základní teorie inverzních úloh a přenosu tepla, na kterou navazuje odvození numerické rovnice přenosu tepla, vhodné pro počítačovou simulaci. Hlavní část práce se věnuje návrhu a samotné implementaci softwarového řešení, s ohledem jak na funkčnost, tak na uživatelskou přívětivost. Kromě výpočtového modelu, který je zodpovědný za průběh simulace, je vytvořeno také plnohodnotné uživatelské rozhraní (GUI), umožňující jednoduchou interakci s výpočtovým modelem. Závěrem práce je prezentování dosažených výsledků a jejich porovnání s reálným experimentem, stejně jako zjištění vlivu vstupních parametrů na kvalitu simulace.

Antoninský Limes: Srovnání Antoninova valu a Odenwaldsko-Neckarské sekce Hornogermánského limitu
Dyčka, Michal ; Musil, Jiří (advisor) ; Rummel, Christoph (referee) ; Collins, Robert Michael (referee)
Despite the Limes Romanus has already been studied for more than 150 years, fundamental questions such as its construction, later modifications and primary function itself are still a matter of dynamic debate. From the historical sources it is currently known that a major role during the construction and planning of the whole system performed so called agrimensores using the simple geodetic tools like groma. Therefore, the essential role during the construction of the Limes had the direct visibility between individual sites of the future frontier. The core of this thesis is the presentation of the results of the so called viewshed analysis of individual sites on the Odenwald Limes (Germany) and on the Antonine Wall (Scotland). Based on combination of this method with results of the other spatial analyses in GIS, the nodal sites for both the surveying and operation of the Limes are detected in each studied sector. The thesis is also dealing with the distribution of the units in the landscape, terrain definition of the positioning of individual parts of the Limes as well as with the possibility of mutual signal communication between individual parts of the frontier. The main goal of the thesis is to shed a bit more light on the fundamental questions: how the Limes Romanus was supposed to operate and...

Etruscan rock-cut tombs and 3D modeling
Votroubeková, Tatiana ; Musil, Jiří (advisor) ; Kysela, Jan (referee)
This thesis examines Etruscan rock-cut tombs that are characteristic for inland southern Etruria and are dated from second quarter of the 6th century BC to the end of 3rd and beginning of the 2nd century BC. Thesis is focused on the architecture of the tombs, their typology, decoration, iconography and their architectural evolution. Main sites in Archaic period are necropoleis in San Giuliano, Blera, Tuscania and for Hellenistic period necropoleis in Norchia, Sovana and Castel d'Asso. Second part of thesis examines the potential of 3D recording, analysis, virtual reconstruction and virtual anastylosis for the study of the tomb façades through the case studies of the "Tomb of the Siren" from necropolis of Sovana and the "Doric Tombs" from necropolis of Norchia. Keywords Etruscans, Etruscan, rock-cut, rupestral, façade, necropolis, 3D modeling, multi-image photogrammetry, virtual reconstruction, virtual anastylosis
