Statistical Approach for BTT probes distribution
Mekhalfia, Mohammed Lamine ; Procházka, Pavel ; Šmíd, R. ; Tchawou Tchuisseu, Eder Batista
Blade tip timing (BTT) system is a non-invasive method used for measuring the blade tip timing of rotating machinery. The BTT system typically consists of sensor probes, signal conditioning system, and data acquisition unit. The sensor probes are placed in proximity to the rotating blade tips, Sensors measure the time at which each blade passes by the probe. By measuring the blade tip timing, the BTT system can detect changes in the blade tip vibration, which is an important for the health monitoring and performance optimization of rotating machinery [1]. To ensure accurate measurement of blade tip timing, the probe arrangement is crucial. The placement of the probe relative to the blade tips can affect the measurement accuracy, and thus, several arrangement algorithms have been developed to optimize the placement of the probes. Instead of considering the condition number, a statistical algorithms is followed to optimize the placement of probes for accurate measurement of blade tip timing in turbo-machinery. The statistical approach will be employed to determine the optimal locations for probes, with the aim of reducing errors in the measurement of blade tip timing. \n

Evaluation of the Financial Situation of a Company and Proposals for its Improvement
Řihák, Adam ; Šmíd, Roman (referee) ; Bartoš, Vojtěch (advisor)
The goal of bachelor thesis is to evaluate financial situation of a chosen company, identify weak sides in this area and suggest measures leading to improvement of company’s financial health on the basis of this analysis. This bachelor thesis will focus on evaluating financial situation and completing financial analysis of San Marco s.r.o. between years 2009-2012 through indicators of financial analysis. San Marco company carries on two family pensions in Mutěnice and vine cellar, which is also in Mutěnice near Hodonín. The bachelor thesis will further take up on suggestions to improve economic situations of the company.

Back and forth between science and reality: Mathematical modelling in tasks with a science context (didactic experiment)
Šmíd Ridzoňová, Ráchel ; Havlíčková, Radka (advisor) ; Vondrová, Naďa (referee)
Mathematical modelling is part of the focus of the educational area "Mathematics and its applications" in the Czech national curriculum and is also a widely studied topic abroad. However, it does not receive much attention in Czech research. This thesis aims to introduce the concept to Czech readers and test the connection of mathematical modelling with science topics and the implementation of modelling tasks in the 5th grade of primary school. The thesis presents mathematical modelling as solving process of a complex problem with a real context in steps (0) undertanding the problem, (1) creating the real model, (2) mathematization, (3) mathematical operations, (4) interpretation of the result and (5) validation of the solution. Modelling competence, the modelling probem, and the relationship to word problems are also described. The chosen qualitative research method of didactic experiments explores the application of a holistic and analytical approach to teaching, identifies the difficult steps of modelling for 5th- grade students, and provides insights into cross-curricular relationships and organizational forms in the teaching of modelling. The research findings positively demonstrate that incorporating modelling tasks into regular lessons and linking them to science topics is possible but...

Digital technologies - development of instructional materials for Grade 6-9 students
Šmíd, Radek ; Brom, Cyril (advisor) ; Černochová, Miroslava (referee)
In 2023, a revision of the Czech national curriculum came into force. The main change was the replacement of the educational area "information and communi- cation technologies" with "computer science". The new curriculum was supported by new educational materials. However, few of these were devoted to the "digital technologies" part of the curriculum. In this thesis we have created new mate- rials that fill this gap. Specifically, we created four worksheets that explain the structure and principles of the Internet. The sheets can, for example, be handed out to students or printed as a poster. The validation of the didactic qualities of the sheets was carried out in two phases: individual interviews and classroom testing. During the first phase, we interviewed fifteen pupils (ISCED-2). The stu- dents first described what they saw using the think aloud method. Then they were questioned about information contained in the sheets. We used the transcripts of the pupils' interviews to improve the clarity of the materials. During the second phase, classroom testing was conducted by giving the finished sheets to a sample of 92 students (age 11-14) to study (20 minutes). We tested students' knowledge using pre and post tests. Statistical analysis of the results revealed a positive effect of studying the sheets on...

Ban on, and restriction of some types of conventional weapons in armed conflicts
Šmíd, Radek ; Ondřej, Jan (advisor) ; Hýbnerová, Stanislava (referee)
57 Summary The subject of my graduation thesis is "The ban and restriction of certain types of conventional weapons in armed conflicts". First, it was necessary to define that as conventional weapons are understood all weapons not being weapons of mass destruction, to explain that the ban and restrictions can take many different forms, and finally, to define, to which kind of armed conflicts the humanitarian rules are to be applied. A brief review of the advance on the field of ban and restrictions of certain conventional weapons has been given, including the historical context. From medieval times, when the only international authority, capable of at least trying to moderate the horrors of war, was the pope, over the first agreements of "civilised nations" in the times before the World War I, to the modern conventions adopted after World War II. Great attention is paid to the Declaration of St.Petersburg and to the so-called law of Hague (consisting of many agreements, today a part of the customary law), which as the first documents state, that the progress of civilization should have the effect of alleviating as much as possible the calamities of war, and they contain the prohibition of use of weapons which uselessly aggravate the sufferings and the Hague law even the prohibition of non-discriminating use...

Student's conception of regularity
Šmíd, Radek ; Novotná, Jarmila (advisor) ; Pilous, Derek (referee)
This paper is a view into the conception of regularity in mathematics. Possible approaches to the concept of regularity in mathematics are dicussed. There is a presentation of the characteristics and relations of regular geometric figures. The conception of regularity on the part of students is explored based on the analysis of the math textbooks. This analysis of textbooks in terms of regularity is also part of the work. The aim is to identify the types of objects which pupils are able to perceive as relationed by regularity of these objects and whether they rather use other criteria when selecting objects that do not belong to the group. Mostly the frequency and manner of expression of selection on the basis of regularity was monitored when analyzing acquired data, as well as the other most common selection criteria and the relations between the criteria used. Keywords: regularity, conception of regularity, geometry, questionnaire
