Yukaghir-Uralic comparison: kinship and social terminology

This article analyzes 25 Yukaghir lexemes designating various kinship and social terms or relations, with their hypothetical cognates in the Uralic languages. Besides 6 terms, which can represent the ‘nursery’ lexicon, i.e. the ‘elementary’ relationships, the remaining 19 items are appellatives, whose semantic dispersions between Yukaghir and Uralic are fully acceptable on the one hand, but on the other hand, they more or less exclude simple adoption from one language entity into another

On the classification of the Samoyedic languages

The article is introduced by a survey and discussion of previous models of classification of the Samoyedic languages. The main part is devoted to a new model of classification, based on the application of so-called recalibrated glottochronology, including a fulldocumentation of wordlists with etymological remarks, statistics and sources. Finally, the present result is compared with previous models. This article follows the study by Blažek 2012, thus completing the Uralic language family

CLASSIFICATION OF SLAVIC LANGUAGES: EVOLUTION OF DEVELOPMENTAL MODELS

The contribution summarizes nearly all the models of classification of the Slavic languages, presented in the past 350 years, from simple enumeration through the qualitative and quantitative approaches, typically leading to the developmental models depicted as tree-diagrams, as well as the linear and net models. The individual models, especially the quantitative ones, are discussed in detail and, finally, correlated with accounts of Byzantine historians.The contribution summarizes nearly all the models of classification of the Slavic languages, presented in the past 350 years, from simple enumeration through the qualitative and quantitative approaches, typically leading to the developmental models depicted as tree-diagrams, as well as the linear and net models.

Baltų *kalu̯ā

The purpose of this contribution is to separate Baltic *kalu̯ā “hill” from Baltic *kalnas “mountain” and to connect it with Indo-Aryan *kū́lva-, Iranian *karu̯a- „thin-haired“; Greek *κόλϝος “docked, hornless”; Italic *kalau̯o- & *kalau̯ā “bald (head)”, and the Pre-Romance oronym *kalauos, besides the Gaulish cognomen calaua. The semantic shift from “bald” to “hill” is supported by numerous examples of “bald hills”.Straipsnio tikslas – atskirti baltų *kalu̯ā nuo *kalnas ir susieti jį su indų-iranėnų *kū́lva-, iranėnų *karu̯a- „plonų plaukų“; graikų *κόλϝος „beuodegis, beragis“; italikų *kalau̯o- & *kalau̯ā „plikas“ ir ikiromaniškuoju oronimu *kalauos, plg. dar galų pravardę calaua. Semantinę raidą nuo „plikas“ iki „kalva“ patvirtina gausūs „plikų kalvų“ pavyzdžiai

Was there a Volgaic unity within Finno-Ugric?

The purpose of the present study is to determine if the Volgaic branch (consisting of Mordvin and Mari) represents a real taxonomic unit in terms of the genetic classification of the Finno-Ugric/Uralic language family

Forecasting of power quality parameters based on meteorological data in small-scale household off-grid systems

Off-grid power systems are often used to supply electricity to remote households, cottages, or small industries, comprising small renewable energy systems, typically a photovoltaic plant whose energy supply is stochastic in nature, without electricity distributions. This approach is economically viable and conforms to the requirements of the European Green Deal and the Fit for 55 package. Furthermore, these systems are associated with a lower short circuit power as compared with distribution grid traditional power plants. The power quality parameters (PQPs) of such small-scale off-grid systems are largely determined by the inverter's ability to handle the impact of a device; however, this makes it difficult to accurately forecast the PQPs. To address this issue, this work compared prediction models for the PQPs as a function of the meteorological conditions regarding the off-grid systems for small-scale households in Central Europe. To this end, seven models-the artificial neural network (ANN), linear regression (LR), interaction linear regression (ILR), quadratic linear regression (QLR), pure quadratic linear regression (PQLR), the bagging decision tree (DT), and the boosting DT-were considered for forecasting four PQPs: frequency, the amplitude of the voltage, total harmonic distortion of the voltage (THDu), and current (THDi). The computation times of these forecasting models and their accuracies were also compared. Each forecasting model was used to forecast the PQPs for three sunny days in August. As a result of the study, the most accurate methods for forecasting are DTs. The ANN requires the longest computational time, and conversely, the LR takes the shortest computational time. Notably, this work aimed to predict poor PQPs that could cause all the equipment in off-grid systems to respond in advance to disturbances. This study is expected to be beneficial for the off-grid systems of small households and the substations included in existing smart grids.Web of Science1514art. no. 525

Innovative bidirectional isolated high-power density on-board charge for vehicle-to-grid

This paper deals with developing and implementing a bidirectional galvanically isolated on-board charger of a high-power density. The power density of the new charger was 4 kW/kg and 2.46 kW/dm(3), and the maximum efficiency was 96.4% at 3.4 kW. Due to the requirement to achieve a high-power density, a single-stage inverter topology was used. Regarding switching losses, due to the topology of the circuit with so-called hard switching, the switching frequency was set to 150 kHz. A laboratory prototype was built to verify the properties and operating principles of the described charger topology. The on-board charger has been tested in a microgrid test platform. Due to the parasitic properties of the transformer and other electronic components, overvoltage with subsequent oscillations occurred on the primary side of the transformer and damped resonance on its secondary side. These parasitic properties caused interference and especially voltage stress on the semiconductor elements. These undesirable phenomena have been eliminated by adding an active element to the charger topology and a new transistor control strategy. This new switching control strategy of transistors has been patented.Web of Science2221art. no. 847

Gr.

The-Greek word   (Archilochos, Aristophanes, Plato, Aristoteles), Dor. ní&anos: "ape", ní-&wv, -wvoi; "little ape" (Pindaros) does not have any convincible Indo-European etymology. The old comparison with Lat. foedus "beastly, foul" etc. is obviously improbable and the word is rather bor­rowed from an unknown source
