Ocean wave energy has de potential to satisfy 15% of EU energy demand, cutting 136 MT/MWh off the CO2 emissions by 2050, as stated by the EU Energy Road Map. Analogously, the Spanish Renewable Energies Plan specifically highlighted the Spanish marine energy potential with special emphasis in wave energy. In this context, Oscillating Water Column (OWC) converters are maybe nowadays the most promising wave energy converters, with the potential capability of sea energy harnessing from diverse on-shore and floating structures. This paper presents an analytic modeling of the wave capture chamber for a fixed on-shore OWC wave power plant. The model is particularized and parameterized for the case of the Mutriku MOWC wave power plant, located in the Spanish Basque Country coast, and then validated using both measured real wave entry data and experimental generated output power from the plant

As knowledge of the biological and biophysical basis of cellular function has increased, opportunities to understand the cellular and molecular functioning of organic matter have expanded, and gene expression microarrays have become a widely used technique to study the dynamics of biological processes. In this paper, we present a gene expression analysis approach using R programming, starting from mRNA oligonucleotide matrices ending with interrelated genes, analyzed within a chosen biological process. © 2022, Politechnica University of Bucharest.

Retinal blood vessel segmentation is an essential component in the diagnosis and monitoring of various ophthalmological conditions, such as diabetic retinopathy, glaucoma or macular degeneration, providing valuable information about the state of blood vessels and ocular blood circulation. Traditional methods for segmenting blood vessels from retinal images present certain limitations in terms of accuracy and robustness, especially under variable lighting conditions, the presence of artifacts or low-quality images. However, current techniques based on convolutional neural networks have demonstrated the ability to achieve precise and robust segmentations in a variety of conditions, outperforming traditional methods. Nevertheless, neural networks face challenges regarding the limited availability of retinal image datasets necessary for training and evaluating these solutions. In this paper we describe a solution for retinal blood vessel segmentation using the U-Net architecture. This neural network achieves impressive results even with very small datasets, demonstrating the efficiency and robustness of the U-Net architecture for retinal blood vessel segmentation.

Worldwide, autism affects 1 in 100 children, with diagnoses steadily rising since the 2000s. Romania lacks official statistics on autism prevalence, but global estimates suggest similarity. Children with autism struggle with social interactions and verbal communication, prompting interest in social robots for therapy and education. Tailored robot-assisted sessions offer potential for cognitive development, vocabulary enhancement, social interaction, and behavioral stimulation like concentration and attention. The NAO robot's user-friendly design, technical capabilities, and integrated features make it well-suited for these purposes. This paper presents activities that exemplify the concept of “learning through play,” allowing children to engage in exploration, experimentation, and effective learning in an enjoyable manner.

The purpose of the work is to investigate the possibilities of soft-start devices with gate turn-off thyristors in electric drives of bow thrusters with adjustable propeller pitch to increase reliability, reduce mechanical shocks and currents, and improve electromagnetic compatibility with the ship's electrical power plant. The characteristic features of these drives are operation on fan load and the need for a smooth start in a sufficiently short time to reduce impact torque in the mechanism. As a result of the analysis, a solution with a shunt capacitor is proposed, which provides high accuracy of regulation of the 1st harmonic of the voltage on the motor according to the given law. The minimum value of the capacitor capacity was found, which for the ABB/AMD710L8T motor with a capacity of 2.7 MW is 150-250 μF at switching frequencies from 500 to 1000 Hz. For the first time, the dependences of the GTO switching frequency on the capacitor capacity and the coefficient of harmonic distortion of the current in the stator phase of the selected motor were found. Frequencies are obtained that correspond to the actual physical characteristics of the GTO (500-1000 Hz). At such switching frequencies, the characteristics of the soft start device practically do not differ from the ideal regulator of the phase voltage of an asynchronous motor. This makes it possible to synthesize closed systems with stabilization of the main coordinates of soft starter electric drive, two-circuit systems with the formation of a given tachogram with torque limitation. All this makes it feasible to implement soft start devices based on gate turn-off thyristors. © 2023 IEEE.

The article deals with methods of usability testing of industrial SCADA/HMI interfaces such as graphical operator panels or control room visualization screens. Analysis of the designed HMI screens and quantitative and qualitative testing methods are used. Usability is estimated by measuring the reaction times of the defined test tasks and by the Eye Tracking methods. The proposed method for testing and evaluating the industrial HMI is presented as a case study. The method allows for to improvement the quality of industrial HMI. Especially its usability, reliability, and efficiency.

Based on the set coverage theory and the multi-objective site selection planning theory, a multi-objective site selection planning model for rescue trains of a railway in mountainous area of China is established. The results show that when four rescue trains are planned to be deployed, two schemes can be obtained, and the average rescue response time of the two schemes is not much different. When five rescue trains are planned to be deployed, five schemes are obtained, of which the average rescue response time of four schemes is very close, and they can be considered as reasonable schemes. When six or more rescue trains are planned to be deployed, the deployment density of rescue trains is too high, resulting in redundancy of rescue resources. Compared with the single objective site selection planning model, the scheme obtained by the multi-objective site selection planning model of the railway in mountainous area of China rescue train can greatly reduce the average rescue response time and improve the rescue efficiency. © ASCE.

Hearing loss impacts over 5% of the world's population, a percent rising due to aging populations, noise exposure, and chronic health conditions. To address this, we developed a non-invasive hearing device designed for individuals with hearing challenges that limit the use of hearing aids. The proposed device integrates a set of Bluetooth headphones with a smartphone, that process the ambient sound in real time through a software application and delivers to the hear impaired patient via bone conduction, bypassing traditional auditory pathways. Laboratory tests confirmed that the proposed device effectively replicates auditory perception. The developed device offers an accessible and user-friendly alternative to patients who cannot use traditional hearing aids.

The single phase H6 topology inverter has the advantages of simple structure, small common-mode leakage current, low current distortion rate and high security, which is very suitable for small distributed photovoltaic power generation system. In terms of suppressing the power grid harmonics of H6 topology photovoltaic inverter, there have been many studies both at home and abroad. For example, traditional PI control has simple algorithm and fast tracking speed, but poor steady-state performance. Repetitive control has good steady-state performance, but the tracking has one cycle lag. In this paper, the harmonic suppression design of voltage controller with notch filter is introduced. Moreover, the simulation and experimental test of designed controller is provided to validate the voltage controller with notch filter for H6 topology inverter has obvious effect on harmonic suppression. © 2022 IEEE.
