In the pedagogy of classical vocal singing, it can be difficult to determine the human voice fach, especially for the voice of aspiring vocalists. Hence, an objective metric-based system for the determination of the human voice is needed. In the present study, we investigated the anthropological and aerodynamic parameters for 60 professional singer...
The development of data-driven prediction models of energy performance of HVAC equipment, such as chillers, depends on the quality and quantity of measurement data for the model training. The practical applications always struggle with the credibility of results when the training dataset of an existing chiller is relatively small. Moreover, when th...

In physics education, understanding error theory is essential for both epistemological and practical reasons, particularly when students encounter experimental uncertainties in laboratory settings. For direct measurements, when random uncertainties were negligible, the experimental error was estimated using instrumental resolution. However, when si...
The article considers the problem of an influence of partial shading on the characteristics of photovoltaic modules (PV modules). Different manners of connections of silicon solar cells contained in such modules are considered, e.g., classical PV modules (I and II generation of modules) and modules made using half-cut technology (III generation of ...
Rolling resistance is a critical factor that influences vehicle energy consumption, emissions, and overall performance. It directly impacts fuel efficiency, tire longevity, and driving dynamics. Traditional rolling resistance tests are conducted on smooth steel drums, which fail to replicate real-world road surface textures, potentially skewing res...
Background: The issue of the relation betweeen training loads on the shape of the spine of young players is of significant importance, as with the advancement of training seniority, unfavorable changes may be perpetuated resulting in possible consequences in the next stages of ontogenesis. The aim of this study was to assess the formation of the sa...
This paper presents an enhanced measurement technique for evaluating embroidered transmission lines (TLs), based on a TL characterization method. The evaluation metric is the “pure” losses of the embroidered TL excluding mismatch losses. Enhanced mechanical stability and removability of embroidered samples under a test is supported by a specially d...

Introduction Buildings that constitute cultural heritage and that are the identity of a defined geographical area are increasingly being restored to offer the community historical places to enjoy. Often the restoration preserves the original structure and building materials, which are usually natural stones. In this study, a radioprotection protoco...
Performing reliable calculations of power system dynamics requires accurate models of generating units. To be able to determine the parameters of the models with the required precision, a well-defined testing procedure is used to record various unit transient signals. Unfortunately, the recorded signals usually contain discontinuities, which compli...
Three-dimensional (3D) printing promises a revolution in laboratory creativity by enabling rapid prototyping, broader availability of scientific apparatuses, and transformative scientific workflows. We believe all chemistry and biology laboratories should equip themselves with one or more 3D printers and a critical mass of scientists trained to ope...
