Flight illusions are defined as a conflict between reality and brain interpretation. The presented project is focused on studying the effect of vestibular illusions (Coriolis illusion and somatogravic illusion) on pilots. Currently, this problem is studied mainly in military pilots and is hardly addressed in the field of civil aviation. Due to this fact, the aim of the project is to analyze the effect of vestibular illusions on civil pilots. Two groups of pilots will be selected depending on the level of expertise to undertake the measurements. The experiment will be based on the collection of physiological data, such as cardiac activity or centre of pressure via stabilometric examination and flight data acquired from the measurements on the Gyro IPT II simulator. Physiological data will be measured before, during and after the simulated flight in order to analyze the changes of these data depending on the reaction of the pilot on the illusion. To compare the flight data, every subject will take two flight profiles - one with illusions and one without the illusions. Physiological and flight data will be later compared and statistically evaluated. The aim of the project is to identify if the level of expertise based on total flight hours affects the reaction of the pilot experiencing flight illusions. The purpose of the study is also to find out the resilience of the pilots in or shortly after the IFR training to specific flight illusions and evaluate the optimality of the standard training which is in the case of flight illusions mostly based only on theoretical training. The whole concept will be evidence based which will provide detailed information about the reaction of the pilot depending on the flight illusion experience. Such a study could contribute to the increase of safety in aviation and to the effective utilization of sources within the flight training.

The presented project concept is focused on the design of a device enabling the collection and provision of data during flight, i.e. an autonomous flight recorder enabling wireless data transmission. Taking into account the current promise of the European Aviation Safety Agency to introduce competency-based training, the use of flight data and their evaluation to increase training effectiveness is expected. Currently, such data can only be obtained from the Electronic Flight Information System (EFIS). However, there are several limitations to this system, notably that not all aircraft are equipped with this system. Other limitations include insufficient sampling rate of recorded data and uncomfortable data transfer to a target device equipped with software for flight data analysis. Thus, it is evident that such device that would be available provides quality data and allows easy and preferably wireless data transfer to the terminal device is absent on the market. For these reasons, the effort will be to create a device that will meet these requirements. Data will probably be collected from multiple sources. The accelerometer and gyroscope will be used as key-stones in the device. Another option that will be subject to evaluation is to retrieve data from an aircraft transponder. Acquired data will be processed in real time and further provided by wireless technology for further use - mainly for applications in mobile phones or tablets. The data obtained from the designed device will be further compared with data from EFIS (currently Garmin G1000 version).

A broad portfolio of available and affordable unmanned aerial vehicles (UAV), their diversity of construction, the level of autonomy and integration of the auto-pilot systems has forced the European Union to modify present drone categorization legislation. New regulation is besides the weight of the UAV now considering also other performance characteristics such as maximum velocity in horizontal flight or maximum height above the launch point. Based on these four specifications is an UAV (drone) assorted into one of the 4 categories. The methodology of testing as well as the testing equipment will greatly influence the accuracy of the proper classification of the product and will affect the pricing. The above will be applicable particularly for the drones of C0 and C1 category with maximum take of weight of 250 g for C0, ev. 900 g for C1. The goal of this project is to propose the affordable methodology of the exact and dynamic testing of the above-mentioned characteristics used for the drone's categorization, in particular the maximum flight height and maximum horizontal speed. The primary focus will be on the Quadro-copters whilst the whole presented project has the ambition to define further flight characteristics that might influence the safety of utilization of unmanned aerial vehicles and their categorization within the valid EU legislation. The outcome of the project will be the creation of the comprehensive methodology of the Quadro-copter testing together with the proposal of the software solution and methodology of the drone categorization in accordance to the selected flight characteristics.

Robot-Assisted Systems for Re-Education of Upper Limb Movement are more and more Used with Limb Movement Disorder Therapies. Those Systems are Constructed with Use of Neurorehabilitation Studies Concerned with Neuronal Plasticity Supported with Feedback Loop Control. Biological Feedback is Usually Realised with Visual Information. One of Main Goals of my Project will be Finding of Simple but Ideomotorical Trajectories which will be Machine Presented and Physically Realised by Assistive Robotical Device. They will Try to Achieve Maximal Fidelity of Trajectory Movements of Upper Limb Rehabilitation Process. Information from Visual Exteroreceptor is Used Together with Feedback Data from Interoreceptors. Upper Limb Rehabilitation Use Mainly Muscle and Tendon Receptors but There is Minimal Use of Haptic Information. Optimalisation of Visual and Haptic Signals Used in Robotical Rehabilitation systems Assumes Development of Appropriate HW + SW Platform which will Allow Measuring of Upper Limb Movement Regularities. Developed Platform will be Used for Research of Kynematics and Dynamics of Effectors during Different Test Conditions. The Goal of the Project will be Completely Solved Functional Prototype of Visual Haptic Platform. This Platform will be Used for Measurents of Upper Limb Regularities of Healthy Individuals with Respect for Natural and Limited Conditions. This will Lead to Determination of Effective Re-Educational Trajectories for Upper Limb Rehabilitation with Use of Visual and Haptic Feedback.

The use of augmented reality in aviation is a result of a constant effort of increasing aviation safety. The idea of augmented reality is commonly used in form of a Head-Up Display or is in testing as a Head-Worn Display (HWD) technology. HWD is a display unit attached directly to the user which implies that its most commonly in form of a helmet or glasses, specifically smart glasses. The projection of augmented reality into a visual field of a user in aviation department is undoubtedly a step forward, but the limitation of these imaging systems is the absence of an analysis of ergonomics of the display of selected data in the field of view. Presented project is focused on removing the above mentioned limitations and designing a concept layout of flight and navigation data from the primary flight display, in terms of both graphical and spatial, respecting the perceptual possibilities of the visible field of the user. The aim is to develop augmented reality software design and to verify HWD application. The software will be implemented in open-source smart glasses, and the way the flight and navigation data will be displayed will be designed with a view to maximize the usability of the presented data.

The presented project deals with real-time assessment of psychophysiological status of pilots. This could help to quickly identification of the workload impact on pilot during the flight. Due to the fact, that pilots are influenced by various stimuli (ambient, G-Forces, mental state etc.) during flight that can negatively affect the safety of the flight. There are already many scientific studies that deal with the psychophysiological assessment of pilots, but the measured physiological parameters are evaluated mostly after the measurement of the entire flight section. There are also studies in which the signal is evaluated in real time, but outside of the aviation field. In these studies, the most frequently used parameter for evaluating of psychophysiological status of respective subjects is heart rate or heart rate variability respectively, due to its distinctive ability to portray the effect of stimuli on the mental and physical state of the subject. Based on the above mentioned, the essence of the project is to assess the suitability and applicability of existing real-time biological signal processing methods. The aim of the project is, among other things, to use existing knowledge on which base the software solution to process measured physiological parameters (primarily heart rate) in real time will be designed. The measurement will be carried out on an air simulator at the Department of Air Transport of the Czech Technical University in Prague.

Increasing aviation safety is the main aim of all organizations that regulate and supervise aviation. At present, the emphasis on organizational factors is constantly increasing and the introduction of management systems such as quality management systems, compliance, safety and fatigue management systems are supported. The long-term approach addresses the maximum service and flight time limits for aircraft and flight crew, which is aimed at transferring responsibility for dealing with fatigue from the regulatory nature to the management systems introduced by the various organizations involved. The benefits of this process are balanced by the need to create new approaches and evaluate unrated data. The proposed project focuses on the area of fatigue in order to allow for improved flight planning efficiency for air operators in ensuring or possibly increasing aviation safety resulting from fatigue management of pilots. This will be achieved by creating a new model of fatigue that includes all the available parameters and the evaluation of not only objective, individual, but also subjective inputs from the pilots.

Projekt se zaměřuje na finální fází letu - přiblížení a přistání na letišti, která patří mezi nejrizikovější z pohledu bezpečnosti. S touto fází souvisí celá řada problematických událostí, jako je nestabilizované přiblížení, dlouhé přistání nebo vyjetí mimo zpevněný povrch vzletové a přistávací dráhy. Všechny tyto události mají společný podíl lidského činitele, který je snaha v leteckém průmyslu minimalizovat. Navrhovaný projekt svým zaměřením přispívá k těmto snahám zcela inovačním řešením - novým konceptem měření, vyhodnocení a analýzy psychofyziologické kondice posádek v této fázi letu. Uživatelem výsledku budou výzkumné organizace, odborná veřejnost a také letecké organizace (letiště, aerolinie, poskytovatelé letových navigačních služeb), které se zabývají výzkumem a tvorbou postupů a procedur definujících průběh finální fáze letu v podmínkách konkrétního letiště a přilehlých vzdušných prostorů. Projekt v tomto kontextu přispěje k další redukci rizika souvisejícího s bezpečnostními událostmi a tím i k redukci nákladů a nežádoucích důsledků s celospolečenským a ekonomickým dopadem.

The proposed project concept focuses on studying the effect of fatigue on pilots' performance. The current state of fatigue tracking in aviation is based in particular on the collection of subjective data right after finishing the flight, i.e. in particular through questionnaire surveys. There are experimental attempts to quantify fatigue through physiological measurements, i.e. monitoring the psychophysiological condition of pilot. However, regarding these attempts, everything is still in the experimental point of view and the measurements are focused only on shorter experiments. For this reason, the present project introduces the concept of 24-hour measurements to create a variable fatigue level with respect to the subject's alertness and day time. During the experiment, there are simulated flights in which biosignals are measured with a primary focus on the brain and heart activity of the subject, and flight data are collected. In the time span between particular flights, battery performance and psychological tests are performed. The project therefore has the ambition to unify the standard methods used and to extend it to those experimentally used, either in the level of data collection or their evaluation, thus creating a complex experiment to study the influence of fatigue on pilots' performance. Such a study could contribute to efforts to objectify and determine the critical level of fatigue. This study could serve as a foundation for efforts to improve air transport safety.

Airports affect economic and social environment of their neighborhood. Their operation is linked to the activities of many other business companies. The airport itself is a business company and so generating profit is one of its goals. In today's highly competitive environment of air transport across Europe, it is important to continually analyze airport revenue and expenditures. An important factor influencing the overall balance is efficiency of individual processes. To allow the required quality of service (especially in terms of waiting times), it is important to ensure consistency between the intensity of input requirements to the system and the intensity of service provided. Among the most important parts of the handling process, which influence all departing passengers and number of other factors and parameters, there are passenger and cabin baggage security checkpoints. Consistency between the intensity of the input requirements (passenger arrival) and the intensity of the service (expressed by the number of operating security check lines) can be explicitly controlled at the checkpoints using analytical methods and simulation tools. Maintaining high level of operational efficiency whilst keeping high level of passenger satisfaction and adhering to strict security requirements is a difficult target. The proposed project, according the dissertation thesis of the proposer, aims to create analytical tools for prediction of the workload of centralized security checkpoints, by the means of mathematical models to create models refining long-term forecasts and based on current operational conditions to create tools for evaluating operational efficiency.

The present project deals with the bases of performance evaluation and psychophysiological stress in pilots. The idea is in selection of appropriate physiological parameters and methods of their evaluation to identify the psychophysiological state of the pilot during the execution of flight operations based on existing knowledge and on usage of biotelemetry. This could lead to identification of stress, fatigue or power states based on non-invasive modular biotemetric systems. The review of current state shows that the evaluation of performance and psychophysiological workload of pilot sis based on monitoring and evaluation of psychophysiological functions. There are plenty of methods how to evaluate such data which are mostly based on linear methods (evaluation in time and frequency domain). Specificity and sensitivity of the methods with the purpose of identification and clasification of psychophysilogical state, or pilots performance, is still unknown. Therefore, the proposed project has the ambition to supplement these common methods with a nonlinear methods, such as recurrence quantification analysis and fractal analysis. The used signals will be primarily myopotentials, electrocardiogram, respiratory rate, body temperature, actigram and electroencephalogram. The main objective of the project is to propose a method of dynamic evaluation of data that can be obtained via wearable biotelemetry systems, and which will allow complex identification of psychophysiological state and pilot performance. Measurements will be performed on flight simulators placed at Department of Air Transport Faculty of Transportation Sciences CTU.

Unmanned Aerial Vehicles are globally one of the most widely discussed themes which contains many questions. One of the most frequently asked questions is how Unmanned access resources from a security perspective and what is their responsibility in terms of their operation. How to use them depends on the feature of their design and to the risk which creates for its surroundings. To determine what risk it creates, it is necessary to verify what damage can UAVs cause in a collision with a man in practice. It may not always be just a deliberate clash in many cases can be an error caused by operator or by malfunctions of the device. This work aims to practically verify what constitutes a risk of UAVs for people who may be at risk, or directly affected by UAVs. Based on the risk assessment determine where and what Conditions can be Unmanned Aerial Vehicle operated in. The operational restrictions will be proposed as amendment of existing as well as future legislation limits of UAVs operation.

Quantitative methods for evaluation of kinematic motion data of body segments are an essential tool in the study of biomechanics of the musculoskeletal system, its structure and behavior. Many methods have been proposed for evaluation of kinematic parameters, including original methods proposed at FBME CTU in cooperation with the 1st FoM, 2nd FoM and FoM in Hradec Kralove. These methods are currently being tested and introduced into clinical practice. Primarily, however, these methods are used to assess postural stability while standing and walking, but are not modified and sufficiently tested for the evaluation of the combined and acyclic movements of body segments. The project is focused on the development and optimization of methods for the quantitative assessment of kinematic data combined and acyclic movements of body segments, in accordance with the requirements of the university hospitals and Faculty of Science. We suppose the use of MoCap systems for measuring kinematic parameters of movement of body segments, in accordance with current requirements of practice and research of nervous system. Methods of quantitative evaluation of kinematic parameters will be based on evaluation of data in time domain, frequency domain and diagrams of interdependences of measured quantities of the combined and acyclic movements of body segments of patients, healthy subjects and animals. The anticipated outcome of the work of master students and PhD students are optimized, developed and tested methods of quantitative evaluation of kinematic data of the combined and acyclic movements of body segments. Scientific results obtained during the testing of the methods will be presented in international journals, in cooperation with associated research groups involved in the measurement and evaluation of the parameters of movement. This will be the General University Hospital, Motol University Hospital, Joint Department FBME CTU and 1st Faculty of Medicine CU and Faculty of Science of
