The paper is dealing with a modification of Interpolating Control (IC) for the employment in trajectory tracking problem with inherent constraints. First, the Optimal Control Problem (OCP) with reference trajectory tracking is described. The OCP is hard to solve analytically, thus, two ...

A hand-eye calibration is used to find the relative position between a robot flange and a mounted sensor, which is a very important knowledge for the automatic control of robotic laser welding systems. Most of the articles deal with a mathematical solution of the equation ...

This paper presents an innovative approach to 3D robotic laser cladding of complex workpieces. To begin, the article brings a brief introduction to the problem and discusses the current state-of-the-art. Next, there is a description of the proposed algorithm which uses data from a&...

Orbit uncertainty propagation (OUP) is an important tracking problem appearing in space situational awareness. The uncertainty, which is initially approximately Gaussian, is transformed by the time propagation and eventually becomes non-Gaussian. Gaussian representation of the uncertainty becomes gradually ...

The breakdown phenomena and determination of dielectric strength is one of the essential topics in the field of insulating materials for high-voltage applications. In the case of basic thermosetting plastics, including epoxy resins, dielectric breakdown analysis has been performed many times,...

This paper deals with a text-to-video sign language synthesis. Instead of direct video production, we focused on skeletal models production. Our main goal in this paper was to design a fully end-to-end automatic sign language synthesis system trained only on available free data (da...

The paper is focused on a description of a system for automatic evaluation of synthetic speech quality based on two-dimensional detection in the Pleasure-Arousal (P-A) scale. The original speech material of a speaker used for synthesis is compared with the synthesized one to find&#...

Any Instrumentation and Control (I&C) system has to be properly tested to minimize the risk of faults in the system. This is even more crucial if the I&C system implements a safety function. The function of the I&C is often designed in a form of Function ...

The paper deals with the novel feedback output control law for multiple-input multiple-output (MIMO) plant with mismatched bounded disturbances. The plant model is described by linear and Lipshitz nonlinear terms. The control law is based on the auxiliary loop method for disturbance est...

Model Checking represents a mathematical method of formal verification which can prove that model satisfies its specified requirements. This article describes an approach that utilizes Function Block Diagram (FBD) models. The key benefit of this approach is the automatic transformation of th...

In this paper, we present our experiments with BERT (Bidirectional Encoder Representations from Transformers) models in the task of sentiment analysis, which aims to predict the sentiment polarity for the given text. We trained an ensemble of BERT models from a large self-collected ...

Equality constrained estimation finds its application in problems like positioning of cars on roads. This paper compares two constructions of confidence sets. The first one is given by the intersection of a standard unconstrained confidence set and the constraint, the second one applies...

The paper addresses the problem of searching the time-to-go function of a double-integrator system with asymmetrically constrained state and control and presents its general analytical solution. The paper further discusses application of the solution in the model predictive control where the ...

The paper deals with a novel functional block for general serial robot coordinate jogging. The functional block is implemented and integrated to the functional block library of the real-time control system REXYGEN and brings new possibilities of rapid prototyping and initial testing of&...

This article presents a gesture-based user interface for a robotic shopping trolley. The trolley is designed as a mobile robotic platform helping customers in shops and supermarkets. Among the main functions are: navigating through the store, providing information on availability and locatio...

This paper deals with the task of information extraction from a structured document scanned by an ordinary office scanner device. It explores the processing pipeline from scanned paper documents to the extraction of searched information such as names, addresses, dates, and other numeric...

The paper deals with automatic evaluation of the quality of synthetic speech using Gaussian mixture models (GMM) for classification in the Pleasure-Arousal (P-A) scale and subsequently calculated 2D and 3D P-A differentials maps. The speech synthesized from the voice of a speaker is...

This paper presents an approach for adaptation of the current visual speech recognition systems. The adaptation technique is based on LipsID features. These features represent a processed area of lips ROI. The features are extracted in a classification task by neural network pre-trained...

Patients who have undergone total laryngectomy and use electrolarynx for voice production suffer from poor intelligibility. It may lead in many cases to fear of speaking to strangers, even over the phone. Automatic Speech Recognition (ASR) systems could help patients overcome this probl...

This paper deals with the task of automatic indoor vs. outdoor classification from image data with respect to future usage in mobile robotics. For the requirements of this research, we utilize the Miniplaces dataset. We compare a large number of classic machine learning approaches&...
