Analysis of influence of transmission parameters on communication quality between pilots and dispatchers
- Branch of study: Aeronautical and Space Engineering
- Department: Department of Measurement
-
Description:
Hypothesis formulation, subjective testing to determine possible relation between communication quality, interactivity and transport parameters. Flight radiocommunication simulator design. http://measure.feld.cvut.cz/vyzkum/hfbm
Analysis of subjects‘ biopotencials in perceptual tests with parallel task
- Branch of study: Bioengineering
- Department: Department of Measurement
-
Description:
EEG and ECG monitoring help to assess the subjects’ performance during subjective tests (listening, visual or conversational). Extensive subjective tests deploying simulated parallel task will be needed and acquired biological signals will be evaluated. Based on EEG analysis, an increased brain activity in the area of the central auditory circles during parallel cognitive or motor task will be explained. Virtual Reality (VR) and Augmented Reality (AR) deployment and automated monitoring of subject test engagement via brain activity monitoring are another potential goals. Candidate‘s prior knowledge in subjective testing and/or biological signals monitoring is advantageous.
Automated uncertainty evaluation of digital impedance bridges based on their characterization and modelling
- Branch of study: Electrical Engineering and Communications
- Department: Department of Measurement
-
Description:
Uncertainty analysis is an integral part of calibration processes. Measurements performed with digital impedance bridges are influenced by several parameters and evaluation of their uncertainty is a complex task, where each part of the bridge (signal generators, transformers, impedance standards under test, grounding currents, their capacitive and inductive coupling…) has to be characterized and correlation between sources of uncertainties has to be evaluated. Due to complexity of applied signal generators, automated testing of their linearity and phase errors on highest metrology level is necessary. http://measure.feld.cvut.cz/vyzkum/metlab
Measurement of Quality Parameters of Telecommunication Network Interfaces
- Branch of study: Electrical Engineering and Communications
- Department: Department of Measurement
-
Description:
Innovation and optimization of speech and audio quality measurement methods in telecommunication networks and for conversational quality measurements. Application of advanced signal processing methods (e.g. wavelet transformation, fuzzy approaches, ...) for the above mentioned areas. New directions in transmitted signal quality measurements - e.g. modeling the influence of the listener's emotional state or using the non-native language. http://meas.fel.cvut.cz/people/holub
