Публікація Квантові точки та їх застосування у медичній візуалізації(ХНУРЕ, 2025) Чубукін, О. С.; Зубенко, O. О.Quantum dots (QDs), are nanocrystals with unique optical and electronic properties that can be tuned to make them ideal for medical imaging. They are used in imaging techniques such as fluorescence imaging and magnetic resonance imaging (MRI), where their magnetic properties improve image contrast. In addition, CT scanners can be used in positron emission tomography (PET), which provides highly sensitive data on biological processes. One of the biggest advantages of CT scans is their multifunctionality, which allows for simultaneous diagnosis and treatment, which is the basis of theranostics. This approach reduces treatment costs and increases its effectiveness.Публікація Радіохвилі проти стін: як сигнал wi-fi проходить крізь перешкоди(ХНУРЕ, 2025) Шубан, К.

A methodology for their reduction is proposed, consisting of two interdependent stages. The first stage consists in calculating and analysing the nature and level of the expected signal according to the developed thermophysical model against the background of the experimentally obtained level of interference. According to the results of the analysis of the calculations based on the thermophysical model for the selected samples, the most influential interference was the heterogeneity of the emissivity of the sample surface. The second stage of data processing is devoted to reducing this interference. The second stage consists of processing the thermograms of temperature fields and includes morphological analysis of the surface condition, filtering, and reduction of characteristic interference. It is divided into four practical procedures. Analysis of the visual image and obtaining a map of zones with the different emissivity of the sample surface, analysis of the thermogram with an assessment of the level of discreteness of the thermogram and the position of the reference points on the image, smoothing of the thermographic image and selection of zones with the different emissivity of the surface of the object under control on the thermogram, followed by noise filtering. Since the results of thermal control are strongly influenced by the shape of the object, the capabilities and effectiveness of the proposed methodology are illustrated on a cylindrical object. The experiment confirmed the validity and correctness of the theoretical statements and allowed us to determine the internal structure of the object under study (different wall thicknesses) and reduce the level of structural interference by 3.6 ˚C. The research shows that the processing of experimental data, which was carried out taking into account the specifics of the thermal and structural characteristics of the objects under control, gives a significant positive result and is an important step towards automating thermal non-destructive testing procedures on the way to implementation in current production
