Sizing of the waves geometrical parameters fabricated on the sheet metal die
Stupárek, Daniel ; Forejt, Milan (referee) ; Samek, Radko (advisor)
This thesis approaches the problem of the return of the original geometric shape of the wave which is created on die panels. Die is used as a structural feature of the fiber-cement roofing material in its shipment in the production line. Based on the study of the theory of cold formed sheet metal determine the actual status in the plant. The method of calibration was designed from the collected informations about the original manufacturer of sheet metal panels. Under this proposal and calculation of the required forming power for the recalibration wave in the factory device for the die calibration was designed and constructed. Equipment calibration was performed on two types of corrugated panels and the result fulfilled the theoretical assumptions. In conclusion is processed technological-economic evaluation and the accompanying drawings.

The Sport Hall in Prostějov
Houška, Daniel ; Štrba, Michal (referee) ; Šmak, Milan (advisor)
The goal of the submitted thesis is a design and assessment of a steel load-bearing structure of a multipurpose sports hall situated in Prostějov. The floor plan measurements of the object are 38x54 m with the maximum ceiling height of 9,5 m. Final design variant was chosen on the basis of two preliminary drafts, both processed according to standard ČSN EN. The structure is designed with respect to ultimate and serviceability limit states. The construction consists of 10 cross-links spaced by 6,0 m. The spatial rigidity of the structure’s main load-bearing system is provided by spatial elliptic trussed girders, longitudinal and sway bracings. Roof cladding is carried by purlins placed on trusses. Steel columns are designed as a part of gable walls. The project was carried out in Scia Engineer 2014 software. Some particular elements were subsequently assessed by means of manual calculation. The thesis also includes assessment of joints, construction details and drawing documentation.

The roof structure of a multipurpose hall in Poděbrady
Houška, Daniel ; Puchner,, Josef (referee) ; Šmak, Milan (advisor)
The aim of this the bachelor thesis is a design of the supporting steel structure of the roofing for the multi-purpose sports hall in Poděbrady. Since a wide range of sports will be played in this sports hall, its layout and ground clearance are proposed accordingly. Prefabricated bleachers, which were not the solved in this thesis, will be part of the hall. Supporting facilities for the hall are located in the nearby buildings. It’s a single steel rectangular hall with a cylindrical roof. Curved beams were used as supporting elements. The beams will be filled with rods installed in a perpendicular system. For a structural analysis Sci Engineer 2011.1 was used. Selected elements were assessed by manual calculation.

Measurement of meteorological variables
Škorpík, Daniel ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor thesis discusses about the basic meteorological variables, especially temperature and airflow. These magnitudes are measured using an anemometer which uses resistive sensors, namely, two thermistors of NTC type that described technology, operations, methods of scanning, sensor placement and implementation of such a device. After that was designed block diagram and circuit diagram. The meter is realized, than we describe the individual components and then is calibrated and tested. In conclusion, it is evaluated for use in medicine.

Parametrical analysis of sound
Matuštík, Daniel ; Sigmund, Milan (referee) ; Zelinka, Petr (advisor)
This bachelor's thesis deals with the processing of acoustic signal. The work includes theoretical models for the processing and classification and shows the spectrogram fuss and cans in different surroundings. Propose here a general procedure for creating a system that includes parametric analysis of the acoustic signal.The Theoretical part of work serves as a preliminary to a recognizer in the programming environment MATLAB.

Modeling of electromagnetic field propation in tunnels
Géze, Daniel ; Motl, Milan (referee) ; Štumpf, Martin (advisor)
Cieľom predloženej diplomovej práce je numerické riešenie šírenia elektromagnetických vĺn v tuneli. Za týmto účelom bola sformulovaná integrálna rovnica a numericky riešená pomocou metódy hraničných prvkov (BEM). Implementácia v prostredí MATLAB sľubne poukazuje na nízke výpočtové nároky oproti štandardným diferenciálnych diskretizačným metódam. Súčasťou projektu je vykreslenie rozloženia elektromagnetického poľa pre rôzne profily tunelov. Overenie výsledkov je vykonané pomocou zjednodušeného analytického modelu. V rámci práce je pozorované štúdium vplyvov zmien profilu tunela a rôznych impedančných podmienok na stenách tunela na výsledné rozloženie elektromagnetického poľa vo vnútri tunela.

Algorithms for anomaly detection in data from clinical trials and health registries
Bondarenko, Maxim ; Blaha, Milan (referee) ; Schwarz, Daniel (advisor)
This master's thesis deals with the problems of anomalies detection in data from clinical trials and medical registries. The purpose of this work is to perform literary research about quality of data in clinical trials and to design a personal algorithm for detection of anomalous records based on machine learning methods in real clinical data from current or completed clinical trials or medical registries. In the practical part is described the implemented algorithm of detection, consists of several parts: import of data from information system, preprocessing and transformation of imported data records with variables of different data types into numerical vectors, using well known statistical methods for detection outliers and evaluation of the quality and accuracy of the algorithm. The result of creating the algorithm is vector of parameters containing anomalies, which has to make the work of data manager easier. This algorithm is designed for extension the palette of information system functions (CLADE-IS) on automatic monitoring the quality of data by detecting anomalous records.

Design of linear ball screw actuator for higher axial load
Turek, Lukáš ; Klapka, Milan (referee) ; Koutný, Daniel (advisor)
This bachelor thesis solves the construction of a servomotor with a moving screw for higher axial loads. The aim was to design a servo actuator for an axial load of 25 kN, which can be clamped from both sides. The partial goals were to develop an overview of electro-mechanical servo actuators, to analyze the force ratios, load capacity and service life of the current actuator solution. Further process the calculation and design of the actuator, including drawing documentation of selected components for higher axial loads.
