Induction of left-right asymmetric gene expression by extracellular fluid flow in ventral node
Šimková, Kateřina ; Vegrichtová, Markéta (advisor) ; Mašek, Jan (referee)
Left-right asymmetry determines the orientation of visceral organs during gastrulation in the mouse embryo. The asymmetry originates in ventral node which is located on the anterior end of primitive streak. Cells of the ventral node possess motile nodal cilia. These cilia rotate and generate leftward flow of extra-embryonic fluid. The leftward flow initiates asymmetric expression of Nodal signalling pathways in nodal cells. Abnormal nodal flow and the interruption of asymmetric gene expression cause reversal arrangement of visceral organs, called situs inversus. The mechanosensing and chemosensing models are the main theories addressing the question of how the leftward nodal flow is sensed by nodal cilia. The mechanosensing model, also referred to as 'two cilia model', is based on two types of cilia, motile and immotile. Motile cilia generate nodal flow while immotile cilia act as mechanosensors with polycystin cation channels. According to the chemosensing model, morphogens are secreted and form gradient that induces asymmetric gene expression in the node. It is still unclear which model is the right one, but it is possible that the final model is combination of both.
Design and static analysis of the house in the shape of inverted pyramid
Fleischerová, Beáta ; Mašek, Jan (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis is focused on design and static analysis of the house in the shape of inverted pyramid. Compiling a 3D model and the calculation are processed by program Dlubal RFEM 5.20 using the finite element method. One of the main aims of the thesis is to be acquainted with the computational program and to verify results of the load cases and their combinations by manual calculation.
Automatic configuration of virtual infrastructure
Kadlíček, Jan ; Mašek, Jan (referee) ; Uher, Václav (advisor)
This master thesis focuses on the issue of automation of virtual infrastructure and available tools such as Ansible, Terraform and Puppet. The individual tools are compared here in sequence for installations or configuration creation. The result of this semester thesis is the selection of a suitable tool for automation of virtual infrastructure.
Xtend GUI regression testing tool
Hamár, Lukáš ; Mašek, Jan (referee) ; Sikora, Marek (advisor)
The diploma thesis deals with regression testing of the Campaign Manager web application of the Xtend product. The work interprets the software development methodologies and subsequently it describes the types of testing that are closely related to development. Furthermore, the work focuses on tools used for the graphical user interface testing and their mutual comparison. The next part of the work is dedicated to the creation of the development environment and it analyzes the structure of test cases that were developed in the created environment. The last section describes how the Campaign Manager was tested and how test results were generated and obtained.
Parallelization of complex tasks in reconstruction of dynamic magnetic resonance
Bijotová, Kateřina ; Rajmic, Pavel (referee) ; Mašek, Jan (advisor)
This thesis deals with parallelization of complex tasks in reconstruction of dynamic magnetic resonance. It describes the basic principle of magnetic resonance and its relation to Fourier transform. It deals with the difference between static and dynamic magnetic resonance image reconstruction. It analyzes SVD algorithm and its use in magnetic resonance image reconstruction. It presents the principles and the importance of parallel computing in magnetic resonance imaging and describes CUDA technology. The thesis also contains a description and execution of the implementation of the reconstruction model in MATLAB and Java programming language which were optimized by JCuda library for Java implementation and gpuArray function in case of MATLAB implementation.

Conditioning of Primary Systems for Solving by Flexibility Method
Sabelová, Katarína ; Mašek, Jan (referee) ; Frantík, Petr (advisor)
This bachelor thesis deals with effect of chosen basic determinate structure on solution of statically indeterminate structures obtained by using force method. Evaluation of basic determinate structure is based on conditioning of flexibility matrix, defined by three different condition numbers. Each of the four analyzed structures is examined in different way, due to their individual characteristics. As a result, few findings about dependence of conditioning of used basic structure on structures parameters and its effect on solution by force method were obtained.
Static analysis of the office building
Golisová, Michaela ; Mašek, Jan (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis contains design and structural analysis of monolitic reinforced concrete frame structure of a high rise office building. Spatial bar model was created from my own design using RFEM software, in which it was then linearly statically analysed using Finite Element Method. RF - CONCRETE plug-in was used for prelminary design of necessary reinforcement.
Robot with autonomous audio-video control
Dvořáček, Štěpán ; Mašek, Jan (referee) ; Přinosil, Jiří (advisor)
This thesis describes the design and realization of a mobile robot with autonomous audio-visual control. This robot is able of movement based on sensors consisting of camera and microphone. The mechanical part consists of components made with 3D print technology and omnidirectional Mecanum wheels. Software utilizes OpenCV library for image processing and computes MFCC a DTW for voice command detection.
System for 3D data visualisation in virtual reality
Kalafut, Oliver ; Mašek, Jan (referee) ; Kolařík, Martin (advisor)
This bachelor thesis deals with the imaging of medical models, for example human body organs, in virtual reality via Oculus Go. Oculus Go is an all-in-one device with a powerful processor and high-resolution display that is ideal for this bachelor thesis. The main goal is the conversion of 2D and 3D medical data formats, including formats such as DICOM and NIfTI, into 3D formats usable for virtual reality and then create the application. The first part of this work is devoted to the theoretical introduction and introduces the issues of virtual reality and 3D modelling to the reader. Then in the practical part, there was implemented a standalone (offline) application for display and interaction of used medical models with users in the virtual reality environment. In total, eight models of different parts of the human body were processed and converted to a uniform 3D Object (.obj) format. Subsequently, they were imported into program Unity, in which I created the entire application environment called Model Preview VR. The application enables viewing, zooming, rotating, and cross-section features of individual objects and is suitable for the presentation of simple models. This application can be helpful for development of not only medical imaging, but also for getting quality photos for publishing.
