Issued topics of Doctoral Study Program:
  1. Advanced methods of signal analysis for localization of partial discharges

    The key issue of high-power power-plant transformers is the existence of partial discharge (PD) activity in their dielectric oil filling. Radiofrequency detection methods may provide new possibilities in PD activity detection, observation and localization. Their recent development is enabled by the availability of advanced instrumentation, which allows signal acquisition with GHz bandwidth. Simultaneously, the availability of high-performance computing platforms enables the processing and evaluation of the digital signals with sample rate in the GSa/s regime and the localization of the signal source in the real time. It is necessary to utilize advanced concepts of UHF signal processing for successful radiofrequency detection and localization methods application. The goal is to detect the PD signal occurrence and determine its time relations, which are essential for following space localization of the PD source. The conducted research will deepen the knowledge in the problematic of PD signal evaluation and the PD source localization, which will lead to increasing the reliability and safety of the high-power power plant transformers.

  2. Computational aspects of the theory of uncertainties

    Theory of uncertainties allows us to specify a tolerance range of direct and indirect measurements. It is an internationally recognized technique based on statistical analysis of uncertainty sources behavior, which may be for instance the measuring instruments, operation, etc. The uncertainty is determined by the uncertainty propagation law. When a complex measurement process is to determine the resulting uncertainty calculation is more complicated and time/computationally intensive. Monte Carlo method is commonly used for complex measurement system evaluation. Dissertation will focus on the general theory of uncertainty, a survey of existing techniques for determining the overall uncertainty and a major part of the work will be focused on the use of the theory of uncertainties in digital measurements using methods of computer vision.

  17. 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.

  18. 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.
