Current transformers effects on the measurement of harmonic active power in LV and MV networks

2011

The harmonic active power is used to determine the location of polluting loads, the direction of harmonic power flow and to estimate how consequential a certain current harmonic source is. The highest uncertainties, when measuring harmonic active power, are introduced by the current and voltage transducers. This paper presents experimental results which show the impact of current transformers (CTs) on the accuracy of the harmonic power measurements. An expression for the evaluation of the power error in distorted conditions was developed which can be easily utilized in the case of linear current transducers. It is shown how CTs cannot be considered linear transducers and how the higher the …

Measurement of Atmospheric Neutrino Oscillations at 6–56 GeV with IceCube DeepCore

2018

We present a measurement of the atmospheric neutrino oscillation parameters using three years of data from the IceCube Neutrino Observatory. The DeepCore infill array in the center of IceCube enables the detection and reconstruction of neutrinos produced by the interaction of cosmic rays in Earth's atmosphere at energies as low as ∼5 GeV. That energy threshold permits measurements of muon neutrino disappearance, over a range of baselines up to the diameter of the Earth, probing the same range of L/Eν as long-baseline experiments but with substantially higher-energy neutrinos. This analysis uses neutrinos from the full sky with reconstructed energies from 5.6 to 56 GeV. We measure Δm322=2.31…

Radiographic Outcomes of Hallux Valgus Deformity Correction With Chevron and Scarf Osteotomies

2023

There is no gold standard in the treatment of hallux valgus deformity. The purpose of our study was to compare various aspects of radiographic assessment following scarf and chevron osteotomies and try to determine which technique helps achieve a more pronounced intermetatarsal angle (IMA) and hallux valgus angle (HVA) correction and produces lower rates of complications, including adjacent-joint arthritis. This study included patients who underwent hallux valgus correction with the scarf (n = 32) or chevron (n = 181) method with a follow-up period of over 3 years. We evaluated the following parameters: HVA, IMA, duration of hospital stay, complications, development of adjacent-joint arthri…

Raman spectroscopy of glycolic acid complexes with N2

2019

High overtone excitation induced conformational isomerization of glycolic acid – nitrogen complex in an argon matrix was investigated by Raman spectroscopy. The interaction between glycolic acid and nitrogen change the green light (532 nm) induced isomerization processes compared to non-complexed glycolic acid. The 180° rotation around of the Csingle bondC bond and stabilization of carboxyl Odouble bondCsingle bondOsingle bondH dihedral angle to trans position were the main conformational changes observed in the complex of the lowest energy conformer and nitrogen. Interestingly, only one stable light-induced conformational product was observed, which isomerises back to the lowest energy con…

Halloysite Nanotubes Coated by Chitosan for the Controlled Release of Khellin

2020

In this work, we have developed a novel strategy to prepare hybrid nanostructures with controlled release properties towards khellin by exploiting the electrostatic interactions between chitosan and halloysite nanotubes (HNT). Firstly, khellin was loaded into the HNT lumen by the vacuum-assisted procedure. The drug confinement within the halloysite cavity has been proved by water contact angle experiments on the HNT/khellin tablets. Therefore, the loaded nanotubes were coated with chitosan as a consequence of the attractions between the cationic biopolymer and the halloysite outer surface, which is negatively charged in a wide pH range. The effect of the ionic strength of the aqueous medium…

5-Imino-3,4-diphenyl-1H-pyrrol-2-one

2014

The title compound, C16H12N2O, exists in the crystalline state as the 5-imino-3,4-diphenyl-1H-pyrrol-2-one tautomer. The dihedral angles between the pyrrole and phenyl rings are 35.3 (2) and 55.3 (2)°. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generate a graph-set motif ofR22(8)viaN—H...N hydrogen bonds.

2,3-Di­phenyl­male­imide 1-methyl­pyrrol­idin-2-one monosolvate

2014

In the title compound, C16H11NO2·C5H9NO, the dihedral angles between the maleimide and phenyl rings are 34.7 (2) and 64.8 (2)°. In the crystal, the 2,3-diphenylmaleimide and 1-methylpyrrolidin-2-one molecules form centrosymmetrical dimersviapairs of strong N—H...O hydrogen bonds and π–π stacking interactions between the two neighboring maleimide rings [centroid–centroid distance = 3.495 (2) Å]. The dimers are further linked by weak C—H...O and C—H...π hydrogen bonds into a three-dimensional framework.

Exploring Skopos in the Dutch Dubbed Versions of the Songs of Disney's Frozen

2018

An important part in dubbing an animated musical film – as in any translation – is setting a purpose (perhaps subconsciously) for that particular project and establishing a set of priorities to achieve that purpose. This article investigates the purpose, or skopos, of the dubbing process of the Dutch songs from the 2013 Disney film Frozen, and analyses the effect of those skopi on the songs. This analysis uses the triangle of aspects, a comprehensive model to compare a dubbed version of a song to the original on several important aspects, such as rhythm, lip synchrony, and sense. It is found that the Dutch songs differ most from the originals on semantic aspects, while they are most similar…

INTEGRATED SFM TECHNIQUES USING DATA SET FROM GOOGLE EARTH 3D MODEL AND FROM STREET LEVEL

2017

Abstract. Structure from motion (SfM) represents a widespread photogrammetric method that uses the photogrammetric rules to carry out a 3D model from a photo data set collection. Some complex ancient buildings, such as Cathedrals, or Theatres, or Castles, etc. need to implement the data set (realized from street level) with the UAV one in order to have the 3D roof reconstruction. Nevertheless, the use of UAV is strong limited from the government rules. In these last years, Google Earth (GE) has been enriched with the 3D models of the earth sites. For this reason, it seemed convenient to start to test the potentiality offered by GE in order to extract from it a data set that replace the UAV …
