India is one of the most diverse media economies in the world and presents incredible opportunities for research in the field of media economics and management. At this point in time, we find that the often scattered contours of this area to some extent are a result of its checkered history and salience within the larger field of communication studies. All this has resulted in only a limited set o
Electric road systems (ERS) allows electric vehicles to charge while in motion, in turn possibly reducing the cost of the vehicle since the battery capacity can be reduced. Most conductive ERS seen today are DC and while static charging is possible from an ERS it is also often beneficial if the vehicle is able to charge from the AC grid as well. In this paper an electric powertrain with the chargi
This paper presents theoretical and practical analyses of four different design options for an electrically excited synchronous machine (EESM) with hollow field winding conductors for internal air cooling. This cooling concept allows for effective direct cooling of the windings.Simulations are performed for the electromagnetic evaluation of the proposed designs, while a plastic 3D printed rotor mo
The market for partly or fully electrified vehicles is expanding fast. The number of sources and loads that are connected to the vehicles traction voltage systems (TVS) increase and thus also the EMC requirements on these sources and loads. These requirements should make sure that neither function nor lifetime of any source or load is severely affected by another. The EMC requirements include both
We sequenced multiple genes from the enigmatic genera Bhagadatta Moore, 1898, Kumothales Overlaet, 1940 and Harmilla Aurivillius, 1892 (Nymphalidae, Limenitidinae) and analysed them together with a large published dataset. We find that Bhagadatta is sister to the genera Cymothoe Hübner, 1819+Harma Doubleday, 1848, and that Kumothales is sister to these three. Harmilla is nested within the genus Eu
We report nonlinear pulse compression of 1.2-ps, 2-mJ pulses. For spectral broadening, we use a Kr-filled Herriott-type cell with 22-roundtrips. After a chirped-mirror compressor, we measure 30-fs pulses, 80% transmission and an M2 of 1.5×1.7.
Opinion mining on social media posts has become more and more popular. Users often express their opinion on a topic not only with words but they also use image symbols such as emoticons and emoji. In this paper, we investigate the effect of emoji-based features in opinion classification of Uzbek texts, and more specifically movie review comments from YouTube. Several classification algorithms are
Eulophidae is a hyper-diverse family of chalcidoid wasps with 324 genera, about 5300 described species and probably thousands of others to be described. Until now, the absence of unequivocal morphological apomorphies and the low resolution provided by the handful of Sanger sequenced genes have hampered the reconstruction of phylogenetic relationships within the family. Here, we used ultra-conserve
IntroductionMulti‐component T2 mapping using a gradient‐ and spin‐echo (GraSE) acquisition has become standard for myelin water imaging at 3 T. Higher magnetic field strengths promise signal‐to‐noise ratio benefits but face specific absorption rate limits and shortened T2 times. This study investigates compartmental T2 times in vivo and addresses advantages and challenges of multi‐component T2 map
What is a musical instrument? A meaningful answer must go beyond the description of a physical object. Depending on the perspective from which the question is asked, it can be answered in many different ways. But one aspect of the answer probably remains – that the identity of a musical instrument shifts through time and across genres, and that it has different potentials depending on the musician
A range of cardiovascular risk factors associated with stroke are known, but they do not explain all cases of stroke. Genetic factors can be responsible for certain forms of stroke, and are further investigated in this thesis. The aims of this thesis were to study the occurrence of familial clustering of stroke, compile known stroke-associated genetic conditions for diagnostic and research genetic
Since the turn of the Millennium, there have been extensive debates on the relationship between the European Union (EU) and civil society. EU institutions have tended to regard associations and organizations of civil society as way to counterbalance the EU’s democratic deficit and/or as a means to foster effective implementation of policies. Much research has accordingly analysed how EU discourses
Previous studies have shown that measurements of beluga whale (Delphinapterus leucas) and bottlenose dolphin (Tur-siops truncatus) echolocation signals at off-axis angles may be well modeled using a Gaussian bell function or a chirped Gaussian function as envelope. In this paper, we apply a novel technique, the matched window reassignment, for investigation of a range of models of dolphin echoloca
