Issued topics of Doctoral Study Program

  1. Advanced methods of radiofrequency detection of partial discharges

    One of the key problems of high-power high-voltage transformers is the existence of partial discharges PD in their dielectric oil filling. Radiofrequency methods may provide an efficient tool for observing the PD activity. The possibility of PD-radiated UHF electromagnetic (EM) signal detection is crucial for successful methods application. This signal has a relatively low magnitude and its occurrence is accompanied by a strong impulse-like interference from other discharge processes. On the other side, the PD signal dispose with specific time and frequency properties, which can be utilized for its reliable detection and evaluation. The theme of the Ph.D. study is focused on the research of new approach to PD-radiated EM signals detection utilizing signal’s specific time and frequency properties. The goal is to deepen the knowledge in the problematic of reliable detection and identification of PD activity and increasing the reliability of the high-power high-voltage transformers.

  6. Controllability problems for discrete equations with aftereffect.

    The aim is to solve some controllabity problems on relative and trajectory controllability for systems of discrete equations with aftereffect. It is assumed that criteria of controllability will be derived and relevant algorithms for their solutions will be constructed (including constructions of controll functions). Starting literature – the book by M. Sami Fadali and Antonio Visioli, Digital Control Engineering, Analysis and Design, Elsewier, 2013 and paper by J. Diblík, Relative and trajectory controllability of linear discrete systems with constant coefficients and a single delay, IEEE Transactions on Automatic Control, (https://ieeexplore.ieee.org/document/8443094) 2158 - 2165, 2019.

  8. Electrical measurements in plasma

    The plasma of radio frequency electrical discharges offers a variety of exciting electrical phenomena due to the coupling of negative and positive charges with enormously different masses. On the other hand, the electrical measurements in plasma can tell us much important information about the plasma processes. The goal of this Ph.D. project is to investigate plasma discharges with high impact in advanced technologies for the processing of nanomaterials and biomaterials. The selection of measurement methods depends on the type of discharge. Radio frequency current and voltage measurement is an essential and convenient tool to monitor process-relevant plasma properties. However, it requires suitable models that relate electrical measurements to the physical properties such as densities, fluxes, and energies of electrons and ions. Langmuir probe and retarding field analyzer are other electrical measurements that provide information about electrons and ions in plasma. They can be used in low-pressure discharges. Fascinating, yet not well-explained, is the appearance of higher harmonics detected either in the discharge electrical circuit or with antennas. Nonlinear plasma behavior relates for example, to a dust (nanoparticles) formation, but the more precise correlation with the plasma processes needs further investigation.

This generalized process is called "differintegration". Systems that can be described by differential equations of fractional order have many applications in electrical engineering. The doctoral thesis should contain both theory and applications and should move forward frontiers in both directions. Detailed topic of the thesis will be specified according to experience and preferences of the selected candidate. Preferred candidates should already have some experience with fractional derivatives and integrals.

  12. High Frequency Ion Thrusters

    Utilization of low and very low Earth orbits (LEO, resp. VLEO) for satellite operations would bring a wide range of benefits. The observation of Earth through the reduced thickness of the atmosphere leads to improved resolution, signal-to-noise ratio (SNR), and is enabling novel technologies and approaches. A high frequency ion thruster is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions using electricity. The different gasses with the different properties are using for the ionization. The gases are ionizing by the high frequency power. The antennas and cavity resonator makes the basis of the high frequency ion thrusters. The frequency tuning and impedance matching is necessary for the correct function of the high frequency structures. The main goal is to deepen knowledge about analysis and applications of the high frequency plasma sources.

  16. Nuclear quadrupole resonance techniques for material detection

    The thesis is focused on the development of techniques for detection of various materials (especially N and Cl based) using nuclear quadrupole resonance. Currently, this method seems to be very promising for the detection and classification of explosives, medicament and drugs. Problems of excitation of cores and subsequent scanning of resonating signal with the possibility of tuning is a relatively complex task both in terms of signal path requirements and in terms of excitation circuit design. Due to the low level of the resonating signal and the short relaxation, it is necessary to solve a number of technical problems. The issue is largely interdisciplinary.

  18. Optical fiber sensing of electromagnetic transients

    The use of a magneto-optical effect in optical fibers is an attractive option for the design of magnetic field and electric current sensors. Their application is particularly interesting in the case of measurements of strong magnetic fields, or currents reaching values in the range of kiloamperes up to tens of megaamperes. In this context, their application in the diagnostics of plasma discharges in future fusion reactors is highly potential. For successful deployment of these sensors it is highly desirable to have the possibility of testing them during development. Many works have already dealt with the measurement of sensor properties. However, the necessary attention has not been paid to the possibility of testing the dynamic properties of the transducers in the nanosecond and sub-nanosecond regions. Moreover, together with the magnetic fields induced by currents of kiloamperes and above. The dissertation thesis will be devoted to the research of properties and testing of sensors in the nano and sub-nanosecond area. The design and development of a unique testing device is expected.

  19. Research of measuring methods for NQR spectroscopy

    The aim of this work is the research of methods for improving the properties of the experimental NQR spectroscope for range of 0.5 to 10 MHz. Suitable measurement methods for elimination of false signals and increase the sensitivity of the spectrometer and repeatability of measurements should be found. The result should be the design and implementation of spectrometer circuitry modifications to verify the effectiveness of the proposed methods.

    Tutor: Steinbauer Miloslav, doc. Ing., Ph.D.

  20. Research of properties and applications of noise electromagnetic fields

    Measuring and diagnostic methods based on the interaction of radiated electromagnetic (EM) field with test objects are currently mature and widely used technology. However, the vast majority of systems based on such approach use the concept of generating and evaluating EM fields with certain defined or swept frequency. In this case, it is necessary to take into account the possibility of reactive coupling of the measured object and the measuring device in the near field, which can detriorate the measurement. Conversely, if broadband stochastic signals (noise signals) were used for diagnostics, these problematic coupling could be suppressed. The topic of the study is focused on the research of the use of the concept of diagnostic of materials and electromagnetic structures by the noise field, especially in radiofrequency and microwave domain, its development and experimental verification.

  21. Spatial Analysis of the Force Load on a Deformed Developing Spine, and Corrective Force Modelling Applied to Minimize the Scope of a Scoliosis Surgery

    Spinal deformity in children (scoliosis) is a condition whose progression cannot be predicted. The results obtained via conservative therapy are problematic, and a certain degree of curvature requires surgical treatment, including the risk of repeated surgeries and complications. The presently used system of growing rods affects, on the average, 9 spinal segments; these become immobile and influence the excessive stress upon the free segments under fusion, resulting in earlier degenerative changes, back pain at a mature age, restrained bodily activity, and damage to the locomotor system. The project is conceived to propose a novel methodology for minimizing the spurious impacts of the surgical treatment of progressive spinal deformity upon child patients, with 3D modeling to define the mechanical stress distribution within the simulation of the planned intervention. The set of patients to be recruited includes individuals with idiopathic, symptomatologic, and congenital scoliosis progressing despite conservative therapy; all these subjects would otherwise undergo spinal surgery. The project aims to design a surgical solution to correct idiopathic, symptomatologic, and congenital spinal deformities by the osteotomy of 1 vertebra. It will exploit 3D modeling to define the stress on the spine, estimation of the spine development and intervertebral discs regeneration by MRI. The project will be carried out in collaboration with University Hospital in Brno Bohunice.

  22. Special methods of measurement of magnetic properties of materials

    The aim of the dissertation thesis will be the design of new and significant improvement of existing methods enabling to determine its material properties for material samples. The focus will be on the measurement of anisotropic magnetization characteristics with the necessary support of numerical methods. For example, new metallic materials in 3D printers exhibit significant anisotropy. Another area will be the measurement of materials with low magnetic susceptibility. Different methods give different results, so the aim will be to compare and unify the results. A special area is the measurement of magnetic liquids. The force methods will also require optimization in FEM.

    Tutor: Drexler Petr, doc. Ing., Ph.D.

  23. Stochastic differential equations in electrical engineering

    By adding some randomness to the coefficients of an ordinary differential equation we get stochastic differential equations. As an example of that is the equation, that describes the current in an RL circuit with stochastic source. Then the solution of the equation is a random process. The subject involves creating stochastic models, numerical solutions of stochastic differential equations and examinations of the statistical estimates of the solutions.

    Tutor: Kolářová Edita, doc. RNDr., Ph.D.

  24. The Theory of Nonlinear Acoustics in Relation to Inhomogeneous Locally Periodic Structures

    Nonlinear acoustics is a comparatively modern research discipline, whose primary focus lies within the propagation of acoustic waves in a nonlinear environment, modelling of the parametric acoustic field, and applications stemming from these areas. In this branch of science, major problems currently awaiting effective solution include, above all, the analytical description and numerical modelling of a non-linear environment. These two subdomains are complemented with another task element, namely the design of inhomogeneous, locally periodic structures, which enable us to target acoustic waves into a beam and to create nonlinear components, such as acoustic diodes. Further, the discussed research discipline may comprise a number of potential application subregions, for example, contactless material testing. Within the doctoral thesis, the student will characterize and analyze amplitude modulated acoustic waves of final amplitudes, and they will also provide an analysis of parametrically excited acoustic fields. In the wider context, one of the central aims of the thesis is to employ inhomogeneous periodic structures, methods for input signal processing, and carrier wave modulation to deepen the present knowledge of nonlinear acoustic interactions in liquids.

  25. Transport of heat by turbulent flows in cryogenic helium gas in Rayleigh-Bénard Convection experiments

    Turbulent flows are found almost everywhere in Nature (think air travel, flow of air around cars, explosions of supernovae, dynamics of quantum vortices in superfluid helium at temperatures close to absolute zero…). One important feature is the enhancement of heat transport in a layer of fluid. To give an illustration of the magnitude - In an atmospheric boundary layer of 1 km height, the turbulent heat transfer increases by at least 5 orders of magnitude compared to the one by molecular diffusion without turbulent air flow. Detailed understanding of this has an obvious value for understanding Earth’s climate or important technological applications such as processes in cooling blankets in nuclear engineering or the storage of renewable energy in liquid metal batteries. Turbulent heat transport can be modelled and studied in laboratory conditions, however the highest intensity turbulence experiments (approaching the conditions relevant e.g. in our planetary atmosphere), as the Rayleigh Benard convection (RBC) experiments in cryogenic helium gas done in our laboratory at the Institute of Scientific Instruments in Brno involve so-called non-Oberbeck-Boussinesq (NOB) effects occurring due to temperature- and pressure-dependence of the working fluid properties, like density, viscosity, or heat conductivity. These are not sufficiently understood, as even the best current numerical simulations work so far only with constant properties, thus the value for understanding large-scale natural phenomena is limited. In collaboration with the team of prof. J. Schumacher at TU Ilmenau, we are working on novel efficient codes involving NOB effects and plan a systematic and careful comparisons with cryogenic helium experiments at ISI Brno. The PhD student will learn deeply about turbulent heat transport and will be able to analyze, compare and interpret data from two different sources – cryogenic helium RBC experiments performed in Brno and massively parallel direct numerical simulations preformed in Ilmenau. The student can also get involved in designing the electronics and instrumentation for data harvesting in upgrades of the ISI experimental apparatus. The interpretation will be done in collaboration with prof. L. Skrbek from MFF UK Prague and prof. K. Sreenivasan at New York University, USA.

  27. Vizualization of quantum and classical turbulent flows of superfluid and gaseous helium by a novel optical method via laser-induced fluorescence of long-living molecular excimers He2*

    Turbulent flows are found almost everywhere in Nature (think of air travel, flow of air around cars, explosions of supernovae, dynamics of quantum vortices in superfluid helium at temperatures close to absolute zero…). One important feature is the enhancement of heat transport in a layer of fluid. To give an illustration of the magnitude - In an atmospheric boundary layer of 1 km height, the turbulent heat transfer increases by at least 5 orders of magnitude compared to the one by molecular diffusion without turbulent air flow. Detailed understanding of this, has an obvious value for understanding Earth’s climate or important technological applications such as processes in cooling blankets in nuclear engineering or the storage of renewable energy in liquid metal batteries. Turbulent heat transfer can be modelled and studied in laboratory conditions, however the highest intensity turbulence experiments (approaching the conditions relevant e.g. in our planetary atmosphere), as the Rayleigh Benard convection (RBC) experiments in cryogenic helium gas done in our laboratory at the Institute of Scientific Instruments in Brno nowadays measure only temperature fluctuations and lack a suitable visualization technique, allowing to measure the flows velocity field. In collaboration with the group of prof. W. Guo at National High-Magnetic Field Laboratory in Florida, who apply a novel and groundbreaking method using laser-induced fluorescence (LIF) of long-living metastable excimers of helium-4 in the regime of superfluid quantum turbulence, we plan to develop an apparatus for visualization of classical turbulent heat transfer by RBC in gas. The work on the PhD student will involve measurements and large data analysis of the experiments in Florida and/or design of the novel apparatus to be built at ISI Brno. The student can also get involved in designing the electronics and instrumentation for data harvesting in upgrades of the ISI experimental RBC apparatus.
