My diploma thesis is focused on the use of numerical computer codes for simulation in plasma astrophysics. They will learn the basic characteristics of the Sun, a closer focus on the solar corona and the solar corona heating problem. The following section is devoted to simulation software in plasma astrophysics, their installing and displaying the results using the visualization software. In the conclusion is demonstrated using this software on a model example and a simulation that performs simulation of impulsively generated waves in solar coronal loops.

Automatic detection and delineation of ECG characteristic points is a basic procedure of any analyze of ECG using computer. This detection is a necessary step to simplify the work of cardiologists to evaluate long ECG records. In this thesis is proposed and evaluate a method of detection and delineation in a single-lead ECG using dyadic wavelet transform followed by correction in pseudo-orthogonal lead system taken from standard 12-lead system. The method uses information about position of positive maximum – negative minimum pair to detect ECG characteristic waves. At first the QRS complex is detected and than its morphology (waves Q and S) and the onset and end of the complex. After that the T-wave is detected and delineated within a searching window dependent on QRS position. And last the P-wave is detected and delineated. There are used two types of wavelets in developed method, “haar” and “quadratic spline”. The developed method was evaluated on CSE database. When haar wavelet was used the QRS detector sensitivity was 99.14%. In the work is also evaluated the accuracy of delineation characteristic points. As the P-wave and QRS complex delineation produced quite good results the T-wave end delineator produced relatively big deviations. All deviations are presented in histograms.

The main objective of this study is to learn about the theory of electromagnetic field and to create a model of propagation of ultra short waves in a biological tissue. Next point of this paper is to determine a specific absorption rate (SAR) using a valid sanitary standard. A particular model solution was realized in a model environment of the program Comsol Multiphysics 3.5. A human head and a cellular phone with an intern antenna were successfully created in this model environment. First of all were entered appropriate parameters which led to a successful representation of the distribution of electric field intensity. A value of specific absorption rate taken by a biological tissue was determined in the next step. This value was compared to the value listed in a valid sanitary standard to prevent its overrun. A development of a temperature in a biological tissue was determined as well, according to a six minutes long interval stated in a valid sanitary standard.

In between the Oceans and the Earth (The cities by Oceans) Projects in between the oceans and the earth For studies of towns on the seashores in magister studies under leadership of Ing. Arch Jan Mlecka I was impacted by two basic factors: firstly by my three years of studies and internships in Lisbon – a metropolis on the shore of Atlantic ocean, which became written into Lisbon’s DNA, into its light, tempo, priorities, historz, courage, strength, eternity, simplicity, sailing boats and elegance. And secondly I was influenced by a workshop organized by AA of London in February 2011 in Dubrovnik with lectures of Vedran Mimica and John Palmesino about towns, growth, quality of town life, policies and by studies of Southern Croatian coast under leadership of Krunoslav Ivanišin, where a floating platform was proposed to simultaneously solve several problems of this region. The more I become involved with oceans, the more I am fascinated by shorelines. This rare, dangerous, fractal line is the theatre of the biggest changes and dramas, but it also presents the greatest possibilities. (This is why I call my work not Towns by Oceans but In Between The Oceans and The Earth). When I was mapping shorelines, I have come across several findings: 1. The principles of constructions on shorelines are similar all over the world. 2. There are similar evolutionary stages in usage of shoreline – it is both physical and functional stages. 3. In many cases the potential of ocean is impaired by human interventions. Taking into account these facts, I was searching for further evolutionary stages of shorelines. In Lisbon I visited Ocean Energy Systems where 30 young engineers work on im-provements of machines designed to extract energy from oceans. In order to be effi-cient, these machines have to have giant dimensions. Immediately after seeing a generator on the island of Pico, I realized that such machines should not be put behind fences, creating an obstacle on the rare shoreline in between the sea and the land, but that they must be adopted by architecture – so that we will be able to live with them in symbiosis on the shoreline.

The thesis deals with research of pulse compression of the acoustic signal in terms of applications in civil engineering. Based on the study and analysis of these methods, automated measuring equipment for non-destructive testing with pseudorandom sequence of maximum length and automated signal analysis, have been designed and implemented. In a single test cycle are obtained three parameters that characterize the linear and nonlinear behavior of the sample. A nonlinear parameter, Time of Flight of ultrasonic wave in the sample is further in the work compared with the conventional pulse measuring, and spectral analysis is compared with the method impact-echo. Functionality and optimization of the testing method was performed on a total of three sets of test pieces made of various building materials. The experiments proved simple result interpretation, and high sensitivity to structural damage associated with temperature loading. The results were correlated with conventional nondestructive methods and by destructive testing was measured change in compressive strength and flexural strength. This work also includes continual measurement of fundamental frequency influenced by moisture on a mortar sample. Use of pulse compression signal is in the civil engineering quite unusual. Only in recent years this topic is discussed in scientific articles with increasing frequency. Great potential lies in the association of three test methods into a single. Beneficial is high test speed and measurement reproducibility, but also theoretical possibility of testing massive test elements.

The following master thesis deals with creating a computational model for acoustic wave distribution by the human vocal tract and then the space around a human head. Detailed mapping of the sound field around the human head is important for more accurate measurement of the human voice. Part of this work is the creation of three-dimensional finite element model of the human head and the vocal tract during phonation of the vowel /:a/ based on the data from the computational tomography. Further the literature search of the function of the vocal tract, biomechanics of the making of the human voice, an overview of the computational models so far published in the literature and in literature reported measurements of the distribution of the human voice by the vocal tract and then in the space around the head . The following is the actual numerical solution of the acoustic waves distribution from the vocal cords through the vocal tract and then the space around the human head when thinking of acoustic absorption on the walls of the vocal tract and on the skin of the head for different types of waking of the model. The results are compared with previously published measurements of the distribution of the human voice and mainly the distortion of the frequency spectra at each specific node in the space around the head and in its vicinity of where the sensor microphones are typically placed are analyzed. Results of the computational modeling will eventually be used for frequency correction for various positions of the microphones scanning the voice distribution in its diagnosis, speech or singing.

This thesis addresses developments in Artificial Intelligence and the increasing trend of robotization and autonomization of military forces in the context of Revolution in Military Affairs. It examines and categorizes different approaches to concepts of AI, autonomy and RMA in the public debate and academic and military literature. It further explores potential impacts and challenges of AI and its weaponized subset - Autonomous Weapon Systems on civil-military relations, legal and ethical norms, arms control regime and general security domain. Building upon findings from previous chapters, AI and AWSs are analyzed in a context of RMA and broader socio-economic context. Specifically, AI-enabled autonomy is compared with aspects of existing remotely controlled systems. The thesis comes to a conclusion that AWSs are harbingers of the next RMA and AI has the potential to match the importance of Neolithic, Industrial and Information revolution.
