Issued topics of Doctoral Study Program
The topic deals with active vehicle noise reduction. Current trends include not only reducing emissions from internal combustion engines, but also reducing vehicle noise. The common approach by modifying the various components of the drivetrain can be very expensive and thus can be a problem for some car companies. Therefore, it is necessary to extend them with more modern approaches such as active noise attenuation using a mechatronic approach and to develop these methods. Therefore, the new approaches would be tested both experimentally and virtually.

The dissertation will deal with the design and optimization of microalgae cultivation photobioreactors. Microalgae are currently considered an important source of biologically valuable substances for use in nutrition, but they can also be cultivated for their ability to capture pollutants from waste gases and waters or to produce biofuels. Microalgae cultivation involves a number of technical and technological challenges, the most significant of which include the reduction of energy consumption, which is one of the main obstacles to the broader adoption of microalgae production. It is possible to approach this by bioreactor design optimization aimed to maximize selected microalgae production. The optimization will take place in the areas of lighting and its economical use, temperature control, regulation of medium mixing and aeration and design of an optimized photobioreactor shape. Microalgae production can be increased by suitable design and regulation of photobioreactor operating parameters. Another energy-intensive part of the technological process of algae production is the separation of algal biomass from the culture medium in which the algae are cultivated. By appropriate design of processes leading to the separation of algal biomass from the culture medium, such as drying, filtration and others, we can significantly reduce the total energy consumption needed to finally obtain valuable usable algal biomass, which is the result of the technological process. Micro-algae technologies can make a significant contribution to meeting the European Union's greenhouse gas reduction targets and will continue to gain in importance when fossil fuel supplies are significantly reduced. New cultivation methods and cultivation equipment will be ready for this transition and will be able to ensure, for example, the production of biofuels or polymers. They can also be used in the pharmaceutical, food, agriculture and many other sectors. The main goals of the dissertation include: • Research part focused on closed photobioreactors in terms of evaluation of their technical and technological limits in comparison with other technologies used for algae cultivation • Experimental operation and construction of closed photobiorectors together with optimization of processes and operating parameters • Research activities in the field of design of optimized lighting, mixing, aeration and harvesting of algal biomass from the culture medium. • Research activities of micro-algal technologies implementation in the area of green technologies

The topic deals with the extension of existing methods for recognizing lanes on the road. The method will be based on neural networks and will focus on the rapid recognition of lanes in adverse weather conditions, where this area is still problematic for driving an autonomous vehicle. The system would be based on products designed for this purpose and tested in operation.
Smart manufacturing machines must ensure both repeatable and accurate behaviour in the production process and their uptime. This goal can be achieved through an advanced metrology system that must account for all potential sources of error and relevant functional criteria for machine accuracy and uptime in proportion to their importance. With an overlap into predictive maintenance, it can then contribute to both quality management and the reduction of greenhouse gas emissions. The issues require a multidisciplinary approach to machine design and associated quality management.

The large amount of data and sensors in the construction of CNC machine tools places increased demands not only on their collection, but also on other parts of the machine design. Greater reliability of the machine function and its maintenance-free operation is required. For these reasons, it is necessary to reconsider the current principles of machine design. This will be systematically discussed in the work. The output will be the methodology of building such a machine tools.
The topic deals with automated data annotation for Deep learning. The current development of autonomous vehicles is combined with artificial intelligence and various types of machine learning such as Deep learning. These neural networks need a large amount of data for their learning. It is used for the classification of objects around autonomous vehicles. In this data, it is necessary to mark the relevant objects in either 2D or 3D. With the common approach of manually creating annotations with respect to the amount of data in the millions and more files, this is not feasible. Therefore, existing methods need to be spread. Or invent new ones so that such a large amount of data can be processed and thus save development time.

The aircraft production and air transport industry (furthermore aircraft sector) is a globalised industrial sector which, in addition to its prestige, contributes significantly to the competitiveness of the economies of countries and their communities, including the EU. The economics, which deals with a particular sector is called a mesoeconomics, i.e. the economics of the sector. In the same way like microeconomics, which deals with the economic behaviour of market actors (customers, companies, competitors) and macroeconomics with the behaviour of countries or their communities, mesoeconomics deals with similar attributes at the level of a particular sector of the economy. The aim of the Ph.D. theses is to analyse EU policies in the fields of aircraft industry and air transport, but also in research and development in order to promote EU competitiveness in the competition with the main players like the US and other dominant countries in the world, in particular China and Russia. The subject of the Ph.D. is to conduct a research on key parameters determining the competitiveness and economic behaviour of key representatives of the EU aviation sector. The analysis of financial indicators that would assess the economic situation of the aircraft sector in Europe through the processing of EU data, complemented by specific analyses of the economic parameters of the behaviour of the key players in the sector in the EU and selected countries, should be one of the results of the research within the study and a starting point for the design of comparative parameters that would allow to identify and assess the impact of the sub-factors determining the sector competitiveness. The analysis of the critical factors determining the economic behaviour of aircraft manufacturers and operators in the light of the crisis situations, which happened in teh last three decades that have affected the sector economy should further contribute to the identification of the risks and the main drivers of the strategic development of the sector and the economic behaviour of main sector representatives. The aim of the dissertation then should be to generalise economic theory to the aircraft sector with a focus on the aircraft manufacturing companies and air transport carriers and to identify the main drivers of the sector competitiveness. The dissertation should also include a comparative analysis of the direct and indirect social and economic impacts, indicated and catalytic benefits of the aviation sector on the economies of countries and economic communities in terms of the impact on employment, gross domestic product, taxes and economic productivity in the EU compared to the US and other economic communities. The result should be a model that would allow forecasting economic development in the aviation sector. This model should be based on cost-benefit analyses of aviation infrastructure, policies, legal and regulatory settings, development influencing factors and should be tested on the specific example of the aircraft industry and transport in Central Europe, including the formulation of theses for a potential strategy for the development of the aircraft industry and transport in the Central European environment in the context of the international environment.

The current development of railway vehicle bogies shows considerable potential for improving ride quality by means of semi-active dampers. The models have so far tested the benefits of fast magnetorheological dampers, which are expensive and too progressive in the conservative community of railway vehicle developers. These problems could be eliminated if conventional semi-active dampers with solenoid valve control were available on the market. However, the change in damping force in response to the control signal of currently available dampers of this type is too slow. The aim of this work is the development and experimental verification of a semi-active damper with a solenoid valve with a fast time response.
Tutor: Mazůrek Ivan, doc. Ing., CSc.
The aim of the work will be to develop a system of intelligent mountain bike suspension. Current commercially available electrically controlled bike suspension systems do not exploit the potential for fast semi-active control. Current systems only allow automatic control of valves, which used to be set manually on older models. However, due to the quality of the ride, these electrically controlled shock absorbers are not able to provide better driving characteristics compared to the optimally set passive or adaptive shock absorber. Fast semi-active damping with magnetorheological dampers enables a qualitative improvement in the achievable driving comfort and wheel grip on the road. Demonstrators of individual components are currently being developed. However, it will be necessary to integrate these components into the entire functional system and experimentally verify the functionality. The focus of the work will be mainly on finding the limiting properties of real elements of the system (dampers, sensors, etc.) and the subsequent design of optimal system control. An important part of the work will be driving tests.
The subject of the study is an atmospheric gas multi-jet burner used for balloon flying. These burners have been developing slowly for decades and the old and proven concept today does not meet the requirements for a comfortable flight. The problem areas are in particular: to reduce water condensate from the air on the fuel exchanger tubes, black flame burnout, poor air access, Radiant heat reduction, flame geometry requirements with respect to the application, Noise reduction These are a number of conflicting requirements that require a systematic approach and a sufficient understanding of the problem. The work will include a theoretical analysis and create a mathematical-physical model of processes, including experimental verification (description, system identification) and modeled first one burner segment), later or the entire burner. Experimental and mainly simulation methods will be used in the development. The doctoral student has a task - describe phenomenologically relevant phenomena, quantify relevant quantities (by measurement, calculation) - propose promising solutions with regard to efficiency and technical, economic, legislative and other constraints. The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to one or more existing or submitted projects and is solved in cooperation with the company BALÓNY KUBÍCEK spol. s r.o. It is assumed that several months of internship abroad, participation in technical seminars and presentations at conferences.

The aim of the work is to design a system for damping of fast shock events. The development of a magnetorheological damping element and the design of its semi-active control are assumed. The research will be supported by the European Defence Agency project.
Separation and gas cleaning applications that are based on liquid sorbents rely on efficient mass transfer in gas-liquid contactors. Liquid atomization is frequent method of increasing the interfacial area in processes where mechanical, thermal or chemical interaction of the liquid with surrounding gas takes place. Several atomizer types (pressure-swirl and twin-fluid atomizers, multi-nozzle plate, or flat-jet arrays) have been proposed and installed in spray towers particularly for CO2 capture with absorption using alkanolamine solutions and aqueous ammonia. The maximization of the interfacial area is the universal primary requirement in gas–liquid absorptive mass transfer operations. For spray scrubbing, the atomizer should produce a uniform spray with drop diameters small enough to generate large interfacial area and at the same time large enough to prevent excessive entrainment. The available literature does not answer what spraying methods suits these aspects best. Several strategies will be studied for uniform film/droplets production and mass transfer enhancement between gas and liquid phases. The main target will be reduction of the spray polydispersisty with selection of the most competitive atomization technique and its further development in line with modification of liquid rheology (non-Newtonian liquids, organic additives). Enhancement of the turbulent mixing process via external field force (ultrasonic irradiation induction, vortex flow in the spray tower) are additional options. Sensitivity of the CO2 capture process to the above aspects will be studied. The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to an existing or submitted project. The possibility of several months of internship abroad, participation in technical seminars and presentations at conferences is expected.

Vibration and acoustic diagnostic tools will be utilized.
The topic deals with the development of methods for creating digital twin of sensors in the automotive industry. For the current trend of autonomous vehicles, it is necessary to sufficiently test the control algorithm and, for example, within the MIL testing to simulate the function of sensors such as lidar, radars, etc. Therefore, a suitable approach is to use a digital twin. For the digital twin to behave realistically in every situation, it is necessary to extend the methods of creating a digital twin of specific sensors and thus improve the development of autonomous vehicles. Verification of new approaches would be on the reference project for the development of autonomous management.
The topic deals with the estimation of vehicle dynamic quantities. For the current trend of autonomous vehicles and electric cars, it is necessary to predict with sufficient accuracy the dynamic quantities that are needed for vehicle control. To this end, it is necessary to develop current approaches with new ones. This means using, for example, deep learning, which is deployed on various applications and significantly helps in development and research. The new approach would be tested on the vehicle and experimentally and virtually validated.
As part of the historical development of aircraft, the arrangement of the crew cabin and the cockpit have been established so that they correspond to valid trends and are reflected in aviation regulations. The development of the last decades, however, brings physiological changes of plots (increasingly taller or more powerful), digitization of the cockpit, electrical controls, but also a change in operating procedures and an increase in the stress load with regard to the ever-increasing traffic density. The goal of the work should be the evaluation of individual factors that are reflected in the pilot's activity, such as the frequency of individual operations or workload and the proposal of recommendations for the layout of the cockpit of GA and UL aircraft.

Actively changing the shape of the wing by in-flight morphing allows for continuous adaptation to the most optimal shape in terms of aerodynamic performance and load distribution. This can improve sustainability of flight by reducing structural weight and power requirements. The goal of the doctoral thesis is the development of control system for aircraft with flexible morphing wing. Control of flexible structures can be challenging due to the nonlinear nature of the system, the complexity of state estimation of flexible structures, and because accurate models of flexible structures are not easy to obtain. Therefore, it is appealing to look for control frameworks which can cope with nonlinearities and which have reduced dependency on the model of the system that is to be controlled. The dissertation is going to be elaborate within the BAANG project submitted to the Twinning call (Horizon-Widera-2021-Access-03) of the Horizon Europe Framework Programme.

Fuel systems of small turbine engines use various methods of fuel supply to the combustion chamber, so there are different fuel nozzle designs, such as pressure swirl nozzles (simplex / duplex), evaporator tubes, spraying rings or airblast nozzles. Fuel nozzles are a very important part of the whole system, their proper function is a must to ensure sufficient engine efficiency and the fuel nozzle requirements are very high. The fuel system must deliver the exact and actually needed fuel amount to the combustion chamber. It is important to ensure good atomization and evaporation of the fuel and its mixing with the air in the entire speed range (engine control range) and especially at start-up. The work aims to classify the fuel nozzles used in turbine engines with a maximum thrust of up to 5000 N (or take-off power up to 600 kW) and to focus on a detailed description of the evaporator system and its modifications. The main subject of the work is the development and testing of the existing evaporator nozzle. The doctoral student will prepare a test stand for nozzle operation, equip it with the necessary sensors and will examine the characteristics of these systems in a given range of operating conditions (eg temperature mapping, determining the control range), assess their suitability for specific purposes and further develop the system with a focus on its problematic aspects. The tasks include: technical research and analysis of published technical solutions, their systematic comparison, evaluation of advantages and disadvantages, range of control parameters and energy requirements, description of design solutions and individual parts, analysis and physical description of their function, design and preparation of test stand for nozzle operation , functional analysis and approximate calculation of energy (heat) balance of the evaporator nozzle The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to an existing or submitted project. The possibility of a several-month internship abroad, participation in technical seminars and presentations at conferences is expected. The work will be solved within the project and in cooperation with the company PBS Velká Bíteš. The practical part of the work will be carried out in PBS testing laboratories and in BUT laboratories.

The aim is to clarify the mechanism of forming a lubricating film in highly loaded contacts lubricated by ionic liquids under the influence of an unsteady electric field. This is an experimental work based on the use of colorimetric interferometry, which includes the development of an experimental simulator for measuring the friction, thickness and temperature of the lubricant.
The thesis deals with the highly topical issue of industrial wastewater treatment. It is focused on wastewater from food processing, where it is contaminated with various organic or inorganic substances. The pressure on the environmental sustainability of industrial processes makes it challenging for companies to treat wastewater in such a way that it is not a significant burden on the environment, i.e. it meets the legislation. The research trend is towards the concept of Zero Liquid Discharge (ZLD) or the less intensive way Minimum Liquid Discharge (MLD) and, where possible, the recovery of both the water itself and the secondary raw materials contained in the wastewater. However, due to the costly investments in technology, this concept is rather an exception in practice. The research activity will include a survey of the current state of the art in the field of WFD and MLD. Furthermore, a mapping of major wastewater producers will be carried out in order to identify one or more case studies for a more detailed analysis in the practical part of the work. The practical part should include the design of a technology for the treatment of the wastewater from the case study and verification of the design on experimental units, including modifications to the equipment if needed. This activity should be followed by tuning the process parameters by the design of experiment, with respect to minimum investment and operating costs. The output of the work should be a ZLD or MLD solution of the case study with minimum financial burden for the potential investor.
The topic deals with the development of hardware for control autonomous vehicles. The current trend of autonomous vehicles brings pitfalls in the form of what hardware to use to deploy the control algorithm. These algorithms contain several neural networks and approaches that are very demanding on the performance of the ECU hardware. This means using powerful GPUs a CPU and arranging everything into a compact ECU. Such an ECU must be able to easily deploy a control algorithm and a simple implementation in a vehicle. This means having peripherals for cameras, lidars, radars, etc. The market offers almost no options for control algorithm developers in this area or has little performance usable only for smaller robots. Therefore, it is important to develop such ECU hardware.
The topic deals with extending existing methods for detecting the distance of an object moving around a vehicle. The method will be based on neural networks, stereo camera or lidar and will focus on quickly determining the distance of the object in adverse weather conditions, where this area is still problematic for driving an autonomous vehicle. The system would be built on products designed for this and tested in operation.
By means of experiments and computational modelling to study impact of differently distributed liquid in a rotating bed, packed with porous structures (different knitted wire mesh) on liquid dispersion inside the bed. The rotating packed bed is aimed at generating high centrifugal force that contributes to a more intense liquid separation inside the bed and a formation of large interfacial surface between liquid and gas that counter-flows inside the wire mesh. The study will focus on different types of liquid distribution (nozzles with different size spectrum, different orientation, full, hollow, flat cone etc.) and the influence of number of rotation and centrifugal force on liquid dispersion inside the bed and/or on the correlation between characteristics of inlet liquid and outlet liquid phase from the rotating annulus. Based on these correlations an optimal liquid distribution on the internal rotating bed will be analysed.

The aim of the work is to find the key operational parameters that influence the generation and especially the propagation of squealing noise in wheel-rail contact with controlled adhesion. It is assumed to develop a suitable numerical simulation model and its experimental verification. The research will be carried out in collaboration with a research institute at Southwest Jiaotong University in China.
The goal of doctoral thesis is research of possibility of a reduction of the overall structural weight of the airframe. This can be achieved by a decreasing of strength demands on the structure by alleviation of load effects due to gust encounters or aircraft manoeuvre. The methods of load alleviation are either passive or active or its proper combination. The passive load alleviation is commonly achieved by aeroelastic composite tailoring, which introduces the desired bend-twist couplings in the wing structure to redistribute the aerodynamic loads closer to the wings root thereby reducing internal structural loads such as out-of-plane bending moments. The research within this thesis will aim to study the capabilities of the meta-materials to further reduce the wing structural weight by providing better passive load alleviation than the composite materials. The dissertation will be solved within the BAANG project submitted to the Twinning call (Horizon-Widera-2021-Access-03) of the Horizon Europe Framework Programme.
With the development of industry and the construction of large units, the potential danger to the population from accidents increases. Linked to this is the need to develop plans to evacuate the population in disaster-stricken areas. In general, two cases can be distinguished where a sufficient number of means of transport must be available to evacuate all residents in the shortest possible time for evacuation; in a less critical case, the population can be gradually withdrawn with small amount of resources. The aim of this work is to model transport operations during evacuation and minimize its completion taking into account all restrictive conditions in relation to the area and the level of risk, such as population density, number and capacity of means of transport, distance of collection points etc.

In applications that serve locations deployed in a large area for certain customer service, it is a typical task to minimise these locations so that each customer has at least one of the centers at the available distance. The problem of coverage for this task has O (2 ^ n) complexity, where n is the number of given places and it is necessary to solve it by heuristic methods for the "large" instances of the problem. However, the task has even more complex formulations considering service capacities and customer requirements. In the dissertation the aim is to apply a general problem solving in the problems of communication of 5G mobile networks and data storage in NoSQL databases.
The topic deals with the optimization of the power elements of the electronic circuit of an electric vehicle. The current trend of electric cars also brings several problems. One of them is the driving distance and the effort is to increase this parameter of the electric car. Therefore, it is very important to pay attention to the power electronics of the vehicle, where there are significant energy losses by switching on and off e.g., Mosfet. Therefore, it is necessary to focus on the development of the electronic components themselves and improve their properties, thus optimizing the entire energy flow management.
The energy requirements of aircraft propulsion will for a long time require high-energy-density resources, ie especially turbine propulsion. The growing demands on the ecology, economics of operation and performance parameters require the continuous development of these devices, better understanding and advanced control of the processes that affect their function. At the workplace, we have long been engaged in research and development of nozzles for spraying aviation fuels into the combustion chambers of turbine engines. After solving the design of the nozzles themselves and the mechanical interaction of the spray with the surrounding gas, it is necessary to deal with other phases of the process, ie fuel evaporation and combustion, including modern trends in turbo engines. The current ambition is to create a workplace that will enable this research and development of advanced jet engines. The doctoral student will solve the preparation of the test equipment, perform experiments on it using modern optical diagnostics and in combination with CFD simulations will contribute to a better understanding of relevant processes. The topic has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is expected. The topic is related to one or more existing or submitted projects and is addressed in cooperation with PBS Velká Bíteš. The possibility of a several-month internship abroad, participation in technical seminars and presentations at conferences is expected.

The topic deals with sophisticated testing of mechatronic systems. Every development of mechatronic systems contains a huge number of tests passed TC and TP and everything is connected via V diagram. This brings great benefits in troubleshooting, but also keeps development costs high and development time. Therefore, many developers in this field are trying to optimize the standard V-diagram approach to reduce costs and time, but at the same time increase the security of mechatronic systems. Therefore, these testing methods and approaches need to be further expanded and optimized using artificial intelligence.
Surrogate-assisted, or meta-model based evolutionary computation uses efficient computational models for approximating the objective or constraint functions, where the evaluations of the true functions are prohibitively expensive (requiring physical experiments or computationally costly simulations). Surrogate-assisted evolutionary computation has found successful applications not only in solving computationally expensive single- or multi-objective optimization problems but also in addressing dynamic optimization problems, constrained optimization problems, and multi-modal optimization problems. The aim of the research is the development of new techniques in surrogate-assisted evolutionary computation and the exploration of novel engineering application areas.
There are a number of methodologies and authorial approaches for the construction of technical objects, especially machine tools.

The aim of the dissertation is to develop an industrially applicable methodology using a systems approach.
Networks, information systems and electronic communications are essential to the economic growth of manufacturing companies. As business processes become increasingly digitalised and cyber-attacks become more frequent, the risk of data loss or loss of production assets due to human error increases. This high risk requires regular assessments of the cyber security and resilience posture of the enterprise. This thesis focuses on the development of risk management and risk reduction practices with respect to human reliability in the area of information and cybersecurity of the production system or the entire production enterprise. The developed procedures must be suitable for comprehensive quality assurance within an integrated management system of a manufacturing organisation.

At present, it exists or is in the interest of a number of manufacturing engineering companies to achieve a modern TPM concept across their production and other departments of the company. In common practice, a number of such successfully implemented examples can be found in series production. For industrial companies with the character of non-series and small series production, the implementation of TPM comes with a number of obstacles, the solution of which requires new, modern and non-standard approaches. The dissertation will be devoted to this. In addition to describing common and advanced procedures, it also aims to find, name and solve the process of implementing TPM in non-series and small series production. It is assumed that the obtained results will be verified in a selected engineering company.

The topic deals with the detection and prediction of failures of either the vehicle as a whole or individual components. The current trend of interconnecting vehicles, gathering information, and creating smart cities is necessary to appropriately predict failures of both various devices and vehicles. Therefore, it is necessary to further develop existing methods by using artificial intelligence and various approaches to machine learning such as Deep learning. An important aspect is the accuracy of the prediction and the associated costs. Therefore, the new approaches would be tested experimentally and virtually.

For the current trend of autonomous vehicles, it is necessary to accurately predict the trajectories of objects around the autonomously controlled vehicle. It is also necessary to monitor other aspects of driving such as intersections, signs, lanes, etc. From this information it is necessary to create a sufficiently accurate virtual world around the vehicle. This means extending methods for a more comprehensive and accurate perception of the environment by combining computational models of vehicles, objects and other information.
