Wind power (WPP) is one of the world's most widespread alternative sources of electricity. The desire to maximize the efficiency of the plant leads to high demands on the mechaniocal design and high reliability of all structural components. Critical components include the driveline bearings. Due to the time-varying loads, it is difficult to reliably determine their service life. At the same time their failure during operation must be prevented, as the entire turbine can be heavily damaged and high reapair cost will be required. The aim of this work is to develop an advanced predictive diagnostic method for monitoring the technical condition of the wind turbine bearings using non-destructive testing methods.

The thesis deals with the highly topical issue of industrial wastewater management. These waters are generated in industrial and agricultural production, where they are contaminated with various organic or inorganic substances. The pressure on the environmental sustainability of industrial processes makes it challenging for producers to treat wastewater in a way that does not impose a significant burden on the environment. As these are often quite complex systems, both in terms of design and operation, which are both investment and operationally demanding, various ways are being sought to make these systems more efficient. Today, machine learning is helping to achieve better results in many areas of industry and there is therefore a possibility of applying it to industrial wastewater management systems as well. This thesis is aimed at investigating the potential of using machine learning in the given problem and several topics are proposed. Wastewater has a very diverse composition and the conditions into which the technology for its treatment is designed are also diverse. One potential application of machine learning is a design tool that would propose an optimal process layout based on inputs (flow rate, composition, output requirements, waste heat availability, etc.) according to a selected criterion (e.g. minimum energy consumption). It would therefore be the use of machine learning and process simulation as a data generator for learning. Other possible area is operation and control. With increasing digitalization, a higher volume of operational data is generally expected, the analysis of which can serve both as a diagnostic tool and as a management support. With sufficient volume of operational data, further potential would lie in the creation of a digital twin technology that could be used for an even more advanced form of control.
Tutor: Máša Vítězslav, doc. Ing., Ph.D.
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.

Colour cameras separate the visible part of the electromagnetic spectrum into three spectral bands. Cameras that can separate the spectrum into tens to hundreds of bands are called hyperspectral cameras. Hyperspectral cameras with a high number of bands work similarly to line cameras, i.e. it is necessary to ensure movement of the camera or of a scanned object so that the entire object is gradually captured. Any additional movement (either of the scanned object or of the camera) leads to unwanted distortions of the resulting image. The main aim of the work is to design methods that suppress or eliminate this type of distortions.

The dissertation will focus on a conceptual and comprehensive approach to developing strategic energy plans in microregions and cities. Due to the newly emerging trend, where the existing energy utilities should be transformed, should integrate higher shares of renewable resources and should reduce the carbon footprint, the need for the creation of a systematic tool is growing. The tool will identify the necessary data, gather the data, analyze the data and creates recommendations. The work will combine theoretical knowledge in energy resource modelling with industrial and municipal sector requirements. One of the critical outputs of the work will be developing a screening tool of technologies for energy production. The tool will respect the specific requirements of the region in which it will be deployed (especially the Czech Republic) and will be based on technical-economic models of relevant detail. Emphasis will be placed on the effective implementation of the tool. The tool will be validated through case studies. Solution procedure: • Familiarization with the issue of municipal energy infrastructure and the aspects that affect it. • Analysis of available data for conceptual modelling • Study and analysis of suitable technologies concerning the geographical and infrastructural limits of the Czech Republic. • Design and implementation of a screening tool • Solution of case studies.
There are many applications of DL in the field of machine vision. This work will primarily focus on semantic segmentation of image data. Semantic segmentation attempts to classify each pixel in an image into one of several classes, such as human, robot, or car. The overall goal of semantic segmentation is to separate objects from the background. Applications include self-driving cars, robot-human interaction, or other computer vision applications where it is important to understand what is happening in the image while rejecting the noise.
Modern area of UAV rotorcraft needs specific design of rotors and particularly rotor blades.

The goal of thesis should be advanced design of rotorblades for high performance UAV rotorcraft.
The current development of rolling stock chassis shows considerable potential for improving the ride characteristics by using semi-actively controlled dampers. The benefits of fast magnetorheological dampers have been verified in simulations currently, but such dampers are expensive and too progressive for conservative rail vehicle development community. These problems could be eliminated if conventional hydraulic semi-active dampers with solenoid valve control capability were available on the market. However, the response of damping force to the control signal in available dampers of this type is too slow. Therefore, the aim of this work is to develop and experimentally verify a semi-active damper with a solenoid valve with fast time response.
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.

This dissertation will aim to develop analytical tools in the field of circular economy, with a specific focus on waste transportation including the algorithmization of efficient search of large networks. The student will expand his knowledge of programming and statistical methods to apply them to monitored data. In developing a novel analytical approach for evaluating extensive studies, the student will utilize existing complex tools such as NERUDA, TIRAMISO, REVEDATO, and POPELKA developed at the Institute of Process Engineering (ÚPI). The student will further develop these tools using newly designed algorithms and thus expand their functionality. The programming activities will focus on appropriate software implementation and utilizing available computational resources. The motivation for this work stems from the need to implement advanced mathematical models into computational tools used in industrial practice. The following issues will be tackled: • Introduction to circular economy and waste management issues and related mechanisms from the operation. • Understanding the principles of existing computational tools at the Institute of Process Engineering (NERUDA, TIRAMISO, REVEDATO, POPELKA, etc.). • Extending knowledge of modern programming techniques and necessary mathematical apparatus. • Development and implementation of algorithms into existing or newly emerging software with a focus on industrially oriented applications.
In military applications, effective shock attenuation is an important requirement. This may include damping of gun recoil, damping of seats in the event of a vehicle explosion or fall, and more. Current scientific contributions reveals that the combination of a magnetorheological (MR) suspension system together with semi-active control can be a significant advance in this area. Typically, piston velocities are in the units of m/s and high damping forces are achieved. These are therefore quite extreme operating conditions for dampers. The main focus of this work will be study of the behaviour of MR fluid at high velocities and the subsequent application of this knowledge to the design of a magnetorheological damper. The design of sensors and damper control will be important as well. The main focus of the work will be the development and experimental verification of MR suspension systems operating at high piston velocities.
The goal is to design and verify the components of the mixing device to achieve the homogeneity of the cement-composite mixture suspension during continuous addition of the base mixture. The extrudate will be additive with one or more components with different rheological properties and chemical composition. In order to ensure the correct properties of the mixture, it is necessary to achieve an even distribution (homogeneity) of the individual mixed components within a relatively short time. Sub-goals: 1. Determination of the methodical development process from simulation through device manufacturing ending by device verification. 2. Definition of the hypothesis about the influence of the selected equipment parameters on the homogeneity of the mixture. 3. Design, manufacturing and experimental operation of experimental prototypes. 4. Description of the influence of the geometry of the mixers on the degree of homogeneity of the mixture. 5. Description of the influence of process parameters of the device (e.g. revolutions) and their influence to material properties and process parameters of 3D printing. 6. The result is either 3 impacted publications or 3 registered intellectual property outputs of at least utility model (can be combined).
The current development of railway boogie shows considerable potential for improving ride characteristics using semi-actively controlled dampers. However, most of the available information is based on data obtained based on simulations. The main aim of this thesis is to verify the benefit of a semi-actively controlled suspension system experimentally. A significant part of the thesis will be developing a suitable damping element and its tests on a single-floor electric unit. Tests on the InterPanter electric unit on a real track are planned for 2024.
Intensive development and research is currently underway in the field of magnetically active elastomers and their applications. These materials can reversibly change their stiffness depending on the applied external magnetic field. An interesting application of these materials are intelligent vibration isolation systems or silent blocks that can real-time respond to loads. The main goal of the thesis is the development and experimental verification of a vibration isolation system working with a magnetically active elastomer.
Nanocoatings, with thicknesses below 100 nm, are used in a wide range of applications where surface properties need to be modified while maintaining the original dimensions. Nano-coatings are widely used especially as protection against abrasion and IR radiation, the advantage of coatings is greater chemical and corrosion resistance, the possibility of altering friction and thermal resistance. Different methods can be used to deposit nanoparticles, such as X-ray lithography, nanografting, electroplating or spray coating. The main requirement is ease of application, low and homogeneous layer thickness over the entire surface. This dissertation focuses on the formation of nano-coatings by spraying, where the final quality of the coating is influenced by the chemical composition of the solution, the concentration of the nanoparticles, the type of atomization device chosen and the interaction of the aerosol with the surrounding environment before application to the surface. The resulting quality of the applied layer may not exhibit optimal parameters if the spray equipment is not properly selected or if the application conditions are inappropriate. The aim of this work is to assess the effect of aerosol formation (grid atomizer, ultrasonic atomizer, dual media atomizer) and ambient conditions (humidity, temperature, flow rate) on the quality of the deposited layer for the chemical solutions used with a wide concentration of nanoparticles. The topic is multidisciplinary. It has full technical and material support, especially laboratory equipment, technology and material for experiments. Partial financial support of the student from the project is assumed. The topic is related to an existing or submitted research project. Several months of internship at a foreign institution with the intention of strengthening international cooperation, participation in technical seminars and presentations at conferences are foreseen. The supervisor will be contacted by the applicant and the details of the study will be discussed prior to admission.

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 main goal of the doctoral study should be to solve the method of approach to the primary aircraft all-composite structure from the perspective of fatigue life. The output of the work should be a methodology for determining the residual life of the structure as a result of cyclic loading only, i.e. without the influence of the environment. The use of a methodology based on the growth rate of delamination is assumed. For experimental research, it is assumed that fatigue tests of samples of all-composite aircraft beams will be carried out. The initial task of the dissertation lever should be to summarize the current knowledge in the field of fatigue behavior of composite materials, tests, definition of different types of life evaluation and requirements of aviation regulations. In the next part of the work, the doctoral student should propose a methodology for determining the service life of the structure, substantiate the methodology with experimental research and process it into a form that enables direct application in industry.
Automated flight control allows system operation with better performance and efficiency compared to human control. It is necessary to consider the nonlinear behavior of the systems as well as the degree of uncertainty of their state variables to achieve the best results. One of the possible control options for such systems is Incremental Nonlinear Dynamic Inversion (INDI). This nonlinear method replaces the need for the exact model knowledge by measuring angular velocities in feedback. Therefore, it is suitable for use on flexible wings as well as fail-safe systems. The INDI method will be applied to a morphable flexible wing within the BAANG project (Horizon Europe Programme, Reg. No. 101079091). Furthermore, the INDI will be applied to FBW topic currently solved at IAE.

Increasing the efficiency of agricultural machinery is one of the tools leading to the development of modern and sustainable agricultural practices. The tractor is considered to be the most representative machine for agricultural production, mainly due to the possibility of combining it with a wide range of working tools, one of which is the front loader, allowing the handling of different types of materials or loads. The position of the machine's centre of gravity (which changes dynamically with the actual position of the front loader) plays a key role in front loader operation in terms of stability and safety (against tipping). Add to this the aspect of dynamic changes in the speed (and reversal) and direction of travel of the tractor, and in practice it is very easy to lose stability (typical combination of fast driving, turning and raised boom of the front loader). Tractor manufacturers have set limits for this type of work in terms of speed, boom height or load weight. Due to the conservatism of these limits, the potential of the machine is not fully exploited and the use of a combination of multi-body modelling and feedback learning tools opens up scope for improving the efficiency and safety of this type of work. The aim of this dissertation is to develop a multi-body based computational model representing the dynamic properties of the key functional units of a tractor front loader assembly, and then to design a virtual environment that allows the application of feedback learning algorithms to optimize the control during a specific work operation. Thus, the resulting computational model will allow a virtual representation of the physical properties of the machine, while the implementation of control using machine learning tools will provide an increase in the efficiency of the performance of a given work process, which in practice is significantly dependent on the experience of the operator.

Experimentally and computationally study two different types of rotating devices designed to release CO2, captured in a liquid "solvent" (which is a liquid chemical that absorbs CO2, such as various amines) in a CCUS - Carbon Capture, Utilization and Storage system. The CO2 that is captured in the absorber must then be released and, after its compression, transported for further use, or stored temporarily in underground geological structures. The release of CO2 from a liquid solvent (called stripping or simply desorption) is energy intensive and requires very efficient equipment. An advanced solution is the use of various rotating devices (rotating packed bed) or discs (spinning disc). In both variants, the solvent must be heated, which is most often done by slightly superheated steam, which heats the rotating surface, from which the solvent is heated and CO2 is released from it. The subject of the doctoral study will be to first assess both variants (rotating packed bed and disc) and then prepare an experimental stand and optimize the function of the stripper with the help of experiments and computer simulations with the goal of the lowest possible energy consumption. Note: To release CO2, it is necessary to bring the desorption heat (to release CO2 itself from the liquid) and the latent heat of evaporation to produce slightly superheated steam to heat the rotating packed bed/disc and the solvent. The task will also be energy consumption, the amount of CO2 released and the possibility of heat recovery from steam condensation. The study will be part of the project of the National Center of Competence Energetika II and cooperation with an industrial partner. From both sources, it will be possible to pay the student a scholarship or pay him a partial salary in another form. During the solution, it is possible to cooperate and maintain contacts with Newcastle University in Great Britain, where you can also go for an Erasmus internship. This doctoral study is suitable for a student of the Institute of Process Engineering or the Energy Institute, and it is assumed that the student will be interested in practical experimental work and computer simulations.

The aim of the work is to experimentally investigate the lubrication of components in space applications that perform only one or a low number of cycles. These may be, for example, pins of pyrotechnic actuators, springs for unwinding solar panels, screws, etc. These components usually only have to complete one duty cycle, but with high reliability. The work will focus on describing the lubrication options for these parts and explaining the nature of the function of each lubricant depending on the method of application and in combination with the materials of the parts.
Magnetically active polymers are materials that can change their stiffness, damping or dimensions depending on the applied external magnetic field. The rate of change of these properties is primarily determined by the composition of the elastomer. It turns out that the rate of change of these properties, to a step change of the magnetic field, is an unexplored area. The goal of the topic is the research and development of magnetically active elastomers with a focus on their dynamic behavior. The results of this research can be used to develop a new generation of vibration isolation systems, sensors or actuators. The use in bioapplications also seems promising.

The dissertation will focus on identifying significant operational parameters in waste collection planning. The newly acquired knowledge will be used for modelling the variability in individual routes and repeating units of the collection plan. The thesis core will consist of a formal description of the proposed models and new heuristic algorithms that consider the stochastic nature of the selected input data. The work results will be used in the POPELKA web application, which is being developed at the Institute of Process Engineering. The following issues will be tackled: • Getting to know waste management, focusing on the operational parameters of municipal waste collection. • Extending knowledge of modern programming techniques and necessary mathematical apparatus. • Statistical analysis of significant stochastic factors affecting production in repeating collection cycles, traffic flow in areas, and the service time of collection points. • Development of optimization models and heuristic algorithms to design waste collection plans.
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.

The support system of CNC machine tools must withstand the effects of external influences so that the machine maintains production accuracy in the long term. The support system is one of the main parts of the CNC machine tool, which plays a significant role not only in production, but also in geometric accuracy. Among the influences that have a negative effect on the machine, we count the change in temperature around the machine, the technology and the chip machining strategy. The geometric shape of the supporting bodies of the machines, the topology and the chosen material from which the body is made can significantly affect the negative consequences arising from temperature changes and the machining strategy. The goal of the work is to use a system approach to find the optimal solution of the support system for this type and type of CNC machine tools.

The aim of the manufacturers of CNC machine tools is to satisfy the customer's needs to the maximum. One of the ways to achieve this is to have a consistent modular system, which will allow the machine tool to be efficiently manufactured according to the customer's wishes from individual building modules. In addition, it is desirable to think about the principles of the circular economy. The aim of the thesis is to select representatives of the type and type of CNC machine tool, on which the principles of modularity and the principles of the circular economy will be applied. All this must be preceded by a thorough analysis of the essential quantities that influence this proposal. The design of the modular system will be consistently solved with a system approach.
The aim is to investigate the influence of process parameters on the multi-material interface of two metallic materials created using the additive process of laser powder bed fusion (LPBF). Part of the job is finding a suitable material combination. The first possible focus is thermally stressed components of the rocket motor body type, where the interface of a copper-based alloy and a nickel superalloy needs to be processed. The second option is to focus on the titanium-aluminum alloy interface, which aims at structural parts of the satellite requiring good strength and at the same time good local thermal conductivity.
n 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 aim of this work is to design a model that will predict the TCP behavior of a multifunctional cylindrical grinding machine based on partial geometric errors of the machine to adjust the compensation on the machine. During the grinding process on a multi-functional cylindrical grinding machine, deviations between the tool and the workpiece occur. These deviations are dependent on the choice of grinding technology. The proposed model will respect the selected grinding technology and adjust the compensation tables accordingly. The work will also include concepts for integrating sensors into the machine to obtain the necessary data for TCP prediction calculations. The output of the work will have a direct impact on the improvement of the geometric accuracy of the multifunctional cylindrical grinding machine.

Noise generated by the operation of rolling stock is an ongoing social problem. One of the main sources of strong noise is wheel-rail contact. In the case of abnormal operating conditions, excessive lateral vibration of the wheel can occur, leading to the emission of a strong acoustic signal. Although some hypothetical mechanisms of wheel-rail contact noise behaviour have been described, a number of phenomena have still not been satisfactorily investigated. Especially in the context of the modern approach of adhesion management on risky track sections through the application of liquid or solid substances to the surface or sides of the rail. The aim of this thesis is to investigate the influence of operating conditions in modified contact on the occurrence of unwanted noise and its propagation to the surroundings.

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.

In the testing of interior safety features of passenger cars, it is possible to use special testing equipment, side sled tests, which significantly reduce the material, financial and time costs for their implementation. Due to the necessity to fine-tune the implementation of the technical experiment and the necessity to use prototype parts, despite the reduction in the number of these parts, the effort is to continue to minimize their number. To minimize them, it is necessary to use data from sensors located on the test rig together with the computational model, which will complement each other and increase sophistication. The aim of this dissertation is to create a digital twin that will not only make use of the sensor data, but will feed back information in real time for sophisticated control of the entire test process. It is envisioned to create a corresponding reduced neural network based model using both supervised and unsupervised deep learning techniques. The condition is to accelerate the generated model using GPU accelerators in both the learning and inference phases. The aim of this work is to consider the possibilities of generative AI for the purpose of accelerating the learning process of parametric reduced model tasks.
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.
The topic deals with the development of a virtual environment for testing autonomous vehicles or their sensors. The trend of autonomous vehicles brings several pitfalls, in the form of safety. This is a challenge for developers, as they are helped by the ISO / PAS 21448 SOTIF standard to increase the safety of such autonomous vehicles or their ADAS assistance systems. Related to this is testing autonomous vehicles in a virtual environment. Therefore, there is a need to expand current methods and approaches. And to develop such a virtual environment including various scenarios for testing either the whole autonomous system or individual sensors such as cameras, lidars, radars, etc.
The topic deals with the creation of a virtual world around autonomous vehicles. 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.
The topic deals with developments in the field of vehicle communication with everything. The current trend of the Internet of Things, smart cities and V2X poses a challenge for developers where security issues may arise or what information to pass on and how vehicles should work with them. The introduction of 5G networks helps to address this issue, and thus the existing methods need to be further expanded or new approaches and applications in the field of autonomous vehicles and electric vehicles can be devised. This means, for example, V2X in the field of communication with charging stations, reservation of free charging points, etc.
