10th International Conference on Mathematical Modeling in Physical Sciences, IC-MSQUARE 2021

The real capacitors' behaviour in electric circuits modelled by a single capacity deviates from the ideal one. In order to find better compromises between precision and simplicity, different C-R-L models are used. In these models, C, R, L are called equivalent parameters and take constant values. Under these assumptions, the capacitors are modelled as lumped parameter subsystems although it is well known that the real capacitors are essentially distributed parameter systems. As highlighted in this paper, the capacitors are also time-variant subsystems. To prove this, we use two types of experimental data: data measured during the capacitor’s discharge process and data obtained from frequency characteristics. The article proposes two estimation methods of equivalent values for the model parameters C and R based on their time variance highlighted by the experimental data. The estimation methods use a system of equations associated with the discharging of capacitors, respectively, with the frequency characteristics via polynomial regression. The experiments were carried out with an electrolytic polymer capacitor rated 220 μF, 25 V, 2.5 A rms, 85 ℃, designed mainly for energy storage and filtering, the results being confirmed by experiments performed on other similar capacitors. © 2021 Institute of Physics Publishing.

Nowadays new information and communication technologies (IT) directly influence teaching methods, practices and resources. The use of virtual reality (VR) technology in education enables new approaches that can enhance, guide, and stimulate students' interest in learning while allowing them to experience the subject and acquire sensory and intuitive cognition in a more personal and realistic environment. This research aims to answer the question: can constructive spatial activity with real materials in real space be replaced by virtual space and digital tools in terms of assessing stability and knowledge acquisition? This current pilot study aims to examine the feasibility of our research setup and analysis methods while children are asked to perform an intuitive creative process to construct a structure in real and digital space. We involved twelve school-Age (8,47 years average) from an elementary school, and we randomly allocated them to group 1 (real space construction) and to group 2 (tablet application construction). We created a behavioral coding scheme for the widely used and validated Noldus Observer XT (version 15) video behavior analyzer software. The video analyses showed that the creation phases defined in the construction process appeared on both real space and in a virtual setting, confirming the assumption that the acquisition of knowledge and skills related to stability can also be phased. Based on our pilot research on a small sample, the chosen observation and research methodology is feasible. We predict that the real-space constructive task applied in the measurement can be replaced by a digital interface to experience stability. © 2023 IEEE.

Accurate localization is essential for wheeled robots in structured environments. This study evaluates the performance of an EKF-based sensor fusion approach that combines odometry with an Absolute Positioning System (APS) under different configurations, analyzing how APS setup variations affect localization accuracy. A line-following, differentially driven wheeled robot was used, providing odometry data. The Ground Truth (GT) database consists of predefined, precisely measured trajectories on which the robot was deployed. Based on these trajectories and odometry readings, APS data were artificially generated, providing virtual measurements with different noise levels. Five trajectories were analyzed, including multiple straight-line segments with directional changes and one semi-circular path. The APS was tested at two update frequencies (1 Hz and 5 Hz) and five noise levels (20,40,60,80, and 100 mm standard deviation (STD)). Performance was evaluated using Root Mean Square Error (RMSE), STD, and Maximum Absolute Error (MaxAE). Results show that EKF-based fusion improves accuracy on straight trajectories with sudden direction changes, while for the semicircular path, odometry alone performs comparably. Higher APS update frequencies enhance localization, while increased noise degrades it. To achieve RMSE lower than 50 mm, the noise level must not exceed 20 mm for 1 Hz APS and 40 mm for 5 Hz APS.

Gaze estimation is an important tool for implementing driver assistance and autonomous driving algorithms. The accuracy of the estimation is crucial considering the impact of failure of such algorithms. In the last decade, an important effort was made to increase this accuracy. However, there are some dynamic conditions that have a great impact on it such as camera vibration determined by road holes or bumps, driver eyes blink or light reflections. The work presented in this paper proposes a modular solution designed to increase the accuracy of gaze prediction independently by the estimation method. It consists of a post-processing step involving a particle filtering solution meant to correct dynamic errors appearing under harsh conditions. To demonstrate the effectiveness of our approach, we use in the validation step an implementation of gaze estimation based on efficient L2CS-Net architecture followed by the particle filter correction module implemented in Python. The test results demonstrate the performance of the presented solution.

The paper is a solution based on machine learning for automatically classifying job titles in AGILE software industry projects. Our methodology incorporates fine-tuning techniques to accurately identify job titles from task descriptions. By utilizing the BERT model, fine-tuned on a dataset of job postings in the software industry, we achieve good performance in understanding contextual information and the semantic nuances of job skills and requirements. The results indicate the model's ability to adapt to various industry projects and accurately identify the project contributors title. These findings highlight the potential of transformer-based models in improving the efficiency and effectiveness of project management practices.

This study focuses on simulating and modeling the behavior of a frequency-controlled asynchronous electric drive using MATLAB/Simulink. The control system is designed using the root locus method along with the Vyshnegradsky diagram. The research examines the system's dynamic response during startup under normal load. The results indicate that the electromagnetic torque can be optimized, with minimal overshot, by selecting specific Vyshnegradsky parameters. Experimental validation shows that the control system achieves an acceptable level of accuracy. Additionally, machine learning techniques such as support vector machine (SVM), random forest (RF), and k-nearest neighbor (k-NN) are used to predict the behavior of key system variables. Evaluation of the models was conducted using two frequently used criteria. i.e., root mean square error and correlation coefficient. RF provided lower RMSE and higher CC in comparison with SVM and k-NN. On the other hand, k-NN provided higher CC, but it generated higher RMSE in comparison with RF. Accordingly, in the training phase, RF was selected for the optimum modeling. © 2024 IEEE.

This paper describes the systems the TUW-Inf team submitted for the HASOC 2021 shared task on identifying offensive comments in social media. Besides a simple BERT-based classifier that achieved one of the highest F-scores on the binary classification task, we also build a high-precision rule-based classifier using a custom framework for human-in-the-loop learning. Both of our approaches are also evaluated qualitatively by manual analysis of 150 tweets, which also highlights possible controversies in the ground truth labels of the HASOC dataset. © 2021 Copyright for this paper by its authors.

In the present paper, the operation of high-power wind turbines of the order of mega-watts (MW), is analysed at significantly variable wind speeds over time. Experimental data from a wind turbine operating in the Dobrogea region are processed, at a higher sampling frequency of measurements. The current operating condition is investigated from an efficiency viewpoint and compared with an optimized controlled setting, in which the electric generator power is controlled dependent on the wind speed value. We find that wind speed sampling frequency is an important factor impacting control quality, while the improved control is mandatory for maximal operation efficiency.

Magnetometers are widely used in sensor fusion frameworks of mobile robots due to their ability to work as compasses. The measurements of these sensors are largely influenced by hard iron and soft iron effects that are caused by nearby ferromagnetic objects. In this paper, an artificial neural network (ANN)-based method is proposed for the identification of such effects, which can be compensated from the measurements. The method utilizes both the distance and the angle of the detected object based on the coordinate frame of the mobile robot as the inputs of the Multi-Layer Perceptron (MLP) ANN. The MLP provides on its outputs the disturbance levels in the three axes, which need to be subtracted from the measurements to obtain the compensated values. The method was tested with three different types of objects to evaluate the performance of the method. Measurements were collected using an industrial robotic arm in a grid around the objects. The disturbance levels generated by the objects were computed by subtracting measurements recorded in an undisturbed scenario. Three-layer MLPs were tested with various numbers of hidden layer neurons to find the optimal configurations. The achieved results show that the disturbance levels can be significantly decreased using the proposed method.

International Symposium on applied Computational Intelligence and informatics ( SACI)

作者： Richard Pesti Peter Sarcevic Dominik Csík Ákos Odry Doctoral School of Applied Informatics and Applied Mathematics Óbuda University Budapest Hungary Department of Mechatronics and Automation University of Szeged Szeged Hungary

Accelerometers, gyroscopes, and magnetometers, constituting the Inertial Measurement Unit (IMU), are among the most fundamental sensors utilized in localization problems. However, their utilization is a challenging task since the reliability of measurements depends on the precision of the executed calibration method. This paper proposes an industrial robot-based infield calibration process in a numerical optimization aided framework, which does not need turntable nor dedicated expensive laboratory setup. The proposed method utilizes a calibrated industrial robotic arm, which is programmed to execute wide variety of motions with comprehensive dynamical ranges. The end effector of the robotic arm is equipped with IMUs with predefined installation errors. The proposed calibration process records the ground truth accelerations and raw IMU data in a database in Robot Operating System (ROS) framework. Then, realistic sensor models are established, and the Particle Swarm optimization (PSO) algorithm is executed with a custom fitness function to obtain the between sensor misalignment and bias errors. The comprehensive analysis highlights that the proposed method effectively determines the calibration parameters. Mean squared error (MSE) performance metrics shows that the precision of these parameters mainly depends on the complexity of the executed dynamical motions.
