The primary objective of this study was to determine the feasibility of classifying emotions into three categories (positive, negative, and neutral) using event-related potentials (ERPs) for individual users. Visual stimuli from the International Affective Picture System (IAPS) database were utilized. Various features, such as signal samples, discrete wavelet transform, discrete Fourier...
This paper uses convolutional neural networks to try to discover the rules of a few exemplary processes.
As the test cases, we consider John Conway's Game of Life and plane wave propagation in a vacuum.
Both processes can be represented as a convolution of a 3-by-3 mask with an image.
In the case of Game of Life, the image is a binary image representing dead/alive cells.
For the wave...
In the paper, we present the machine learning algorithm to predict 100m men’s outdoor sprint score. For this project, a unique dataset of 17 features was created. The training set contained 174,383 records, whereas the test set contained remaining 406,894 records (proportions: 30% of training data to 70% of test data). The proposed multi-layer MLP model is based on set of features, such as...
The paper presents a study concerning recognizing user emotion based on keystroke dynamics of the written text. At first, the analysis of the dataset used in the task is performed. Followed by the training and the effectiveness assessment of classical methods: Naive Bayes, K-Nearest Neighbours, Random Forest, and Multilayer Perceptron applied to the classification of provided samples to one of...
The work deals with the analysis of a digital recording of cough sounds. This signal was obtained using a digital recorder with a microphone placed on the patient's chest. The wavelet transform was used in this work. The principle of its operation, various wavelet functions, and types of these functions are described. The core of the work is the continuous wavelet transform algorithm. The...
The article presents a system for monitoring fluid during intravenous infusion. The system is based on a capacitive method in which the change in electrical capacitance of the infusion container is converted into the current volume of the fluid. The capacitor pads of the measurement system are integrated into the housing of the container, facilitating easy installation in hospital conditions...
An electromechanical system (EMS) for adjusting the arc lengths of an arc furnace (AF) using a fuzzy model for the electrodes movement control is proposed. A fuzzy impedance-admittance law to form the electrical mode (EM) mismatch signal is created and the use of a fuzzy corrector for the electrode motion control signal is validated. A parametric synthesis of the fuzzy corrector based on the...
This paper presents the application of ANSYS circuit simulator for the identification and evaluation of the potential sources of electromagnetic disturbances in the high- current laboratory environment. Use of the computer model of the test circuit and comparison of the simulation results with the measurements allowed to confirm the hypothesis that the characteristic patterns of transient...
The research aimed to verify the adopted methodology for testing transients in circuits with inductive elements during their disconnection. The main focus of interest is the electromagnetic disturbances named electrical fast transients (EFT/Burst) that occur on this occasion. The analytical derivation allowed us to know the nature of the transition state and various cases that depend on the...
Electromagnetic nondestructive evaluation of conductive biomaterials using the sweep frequency eddy current method is the subject of this work. The main aim is to verify its use in the investigation of artificial defects that are located inside the austenitic stainless steel. For this purpose, numerical simulations and experiments were carried out, the results of which will be compared and evaluated.
This paper introduces a Finite-Difference Time Do- main (FDTD) electromagnetic field solver focused on speed and low-memory usage. It solves both electric and magnetic fields on axisymmetric grids. The accuracy of the code has been compared to the equivalent Finite Element Method (FEM) models in 2D and 3D. Finally, the performance metric of the FDTD solver has been estimated and compared with...
The article presents the proprietary development version of the system for monitoring and detecting a low level of infusion fluid, initiated by a medical university. The results presented earlier by one of the coauthor are the basis for expanding the functionality of the measurement device. Additional features include the handling of multiple containers with liquid by a single station (just as...
The article presents analysis of static compensator influence on average power flow. It is shown that the compensator current affects on the power delivered to the consumers. The real time iterative method of compensator control in was presented. The RMS value of grid voltage is chosen as the target of the compensator. The results prove the effectiveness of the proposed control method.
This scientific article explores the impact of collision chemistry on Townsend’s avalanche development through an innovative computational approach. By combining the Particle- in-Cell (PIC) algorithm and Monte Carlo (MCC) collisions, we determine the first Townsend coefficient for Helium gas. Further, we investigate the influence of a variable number of collisions in our simulations to achieve...
This scientific research is devoted to the analysis and testing of the Haar cascade classifier method for face recognition. The paper also justifies the choice of algorithm and provides a description of the implementation of the system on which the analysis was conducted. During the research, the developed system was tested on a sample of facial photographs that included images at different...
The article describes the concept of steganography from the point of view of the issues of the physical and digital world. It discusses the basics of hiding information in data medium, indicates the potential in terms of their capacity and susceptibility to the phenomenon of data concealment. It also indicates aspects of the suitability of modified data for information retrieval and...
This paper discusses the simulation of radiofrequency electromagnetic field thermal effects on the male urogenital system. It aims to simulate the radiation of a mobile phone, which can be placed in the pocket of the person using the device. A voxel model was used, which was modified only for the lumbar region. Several simulations were created with different antenna power values. Even with the...
