This paper describes the design of a robust PI controller by considering several design criteria simultaneously (multi-objective optimization). Firstly, all controllers satisfying multiple frequency domain criteria (e.g.&#x...

This paper introduces an integrated approach to calibration and optical measurement processing in the area of robotic 3D vision. The target robotic work-cell consists of a 6-axis industrial manipulator extended by a linear rail and a 2-axis positioner, a color 3D camera and a ...

This article describes a process for modern verification of safety-related I&C (Instrumentation and Control) systems based on algorithm model checking, model-based test case generation and automatic testing. The verification process is compatible with IEC 60880 standard, and utilises methods prese...

This article introduces a newly modified evaluation of a relative position between a profile scanner and a cuboid calibration object, which is used for a hand-eye calibration of the profile scanner as a robot tool. First, the problematic part of the evaluation of the system&#x...

This paper deals with the state estimation of non-linear stochastic dynamic systems with an emphasis on a probability density function approximation used by point-mass filters. Approximation error of the standard point-mass density is analysed and quantified, and a novel point-mass density a...

Magnetic bearings are complex devices with various uses. In addition to rotor support, they can also be used as a contactless active vibration compensator or vibration exciter in the rotordynamic experiments. When testing rotor dynamics, it is necessary to quantify the force acting ...

Structural health monitoring is a fundamental task to evaluate the condition of the structure and ensure an early detection of any material failure. This is important especially in highly stressed parts of a structure. In turbomachinery, it is in particular a rotating blade that&#x...

Linear fusion of estimates has been studied from the perspectives of known and unknown correlations of estimation errors. Whereas optimal linear combinations can be designed in the former case, a robust approach is usually chosen in the latter one. The loss of performance may ...

Condition monitoring is the process of signal measuring and processing to detect an early change in the system. In turbomachinery, blade state monitoring is an important task of this kind. It is important, especially in terms of the last stages of the low-pressure turbine. In&...

Decentralised estimation often sacrifices optimality for solution simplicity, while within the fusion under unknown correlation, a worst-case type of optimality is adopted. This paper studies the gap between the simple solution and the optimal one for special cases. Namely, symmetric configuratio...

Building a robust and accurate AI-driven system for automatic snake species identification is an important goal for biodiversity and global health. As the existence of such a system can potentially help to lower deaths and disabilities caused by snakebites, we have prepared SnakeCLEF202...

In this paper, we propose to frame glottal closure instant (GCI) de- tection from raw speech as a sequence-to-sequence prediction problem and to explore the potential of recurrent neural networks (RNNs) to handle this prob- lem. We compare the RNN architecture to widely used c...

This paper presents a cloud-based multi-modal human-robot interaction architecture. The architecture consists of parts running on the edge (mobile) platform and cluster services. Software on the mobile platform is represented primarily by a Robot Operating System, an MQTT broker and the clie...

The paper deals with the development of an experimental benchmark mechatronic system that was employed in control courses taught at our university. The first part introduces its mechanical design, installed instrumentation and software environment. Methodology of its use in terms of our ...

This paper deals with the state estimation of the nonlinear stochastic models with continuous dynamics and discrete measurement. Namely, the numerical solution to the Fokker-Planck equation, representing the estimator time update, is explored. Unlike the classical approaches, which use the finite...

Building accurate knowledge of the identity, the geographic distribution and the evolution of species is essential for the sustainable development of humanity, as well as for biodiversity conservation. However, the difficulty of identifying plants, animals and fungi is hindering the aggregation&#...

The paper deals with the development of an experimental mechatronic system for battery management of drones called Droneport. It was developed as an automatic system with battery swapping and recharging feature set outside the drone, allowing a quick return to a mission. The first&...

Prosodic boundaries in speech are of great relevance to both speech synthesis and audio annotation. In this paper, we apply the wav2vec 2.0 framework to the task of detecting these boundaries in speech signal, using only acoustic information. We test the approach on a set ...

Czech is a very specific language due to its large differences between the formal and the colloquial form of speech. While the formal (written) form is used mainly in official documents, literature, and public speeches, the colloquial (spoken) form is used widely among people ...

In this paper, we investigate two research questions related to the phonetic representation of input text in Czech neural speech synthesis: 1) whether we can afford to reduce the phonetic alphabet, and 2) whether we can remove pauses from phonetic transcription and let the spe...
