Groups with few $p'$-character degrees
2019
Abstract We prove a variation of Thompson's Theorem. Namely, if the first column of the character table of a finite group G contains only two distinct values not divisible by a given prime number p > 3 , then O p p ′ p p ′ ( G ) = 1 . This is done by using the classification of finite simple groups.
System identification via optimised wavelet-based neural networks
2003
Nonlinear system identification by means of wavelet-based neural networks (WBNNs) is presented. An iterative method is proposed, based on a way of combining genetic algorithms (GAs) and least-square techniques with the aim of avoiding redundancy in the representation of the function. GAs are used for optimal selection of the structure of the WBNN and the parameters of the transfer function of its neurones. Least-square techniques are used to update the weights of the net. The basic criterion of the method is the addition of a new neurone, at a generic step, to the already constructed WBNN so that no modification to the parameters of its neurones is required. Simulation experiments and compa…
Normativité des choix sociométriques et différences sociodynamiques dans la représentation sociale des relations entre nations européennes
2007
Exploring sociometric between 39 different nationalities within Europe, we identified a social representation of relationship between these nations.
Representation
2020
Representation is a primitive notion of many philosophical theories and of cognitive science. It is assumed as an intuitively understandable label assigned to the functions by which a biological or an artificial agent takes part in the world in an epistemological or a behavioral manner. It is employed to define the conditions for the semantic individuation of the states of the agent. The notion of representation was introduced systematically in the Scholastics’ view of cognition. In modern philosophy, the term is often used as a verb. Representation becomes the function of a class of mental states. In contemporary philosophy, the debate over the semantic individuation of states is intertwin…
Matilde Ucelay Maortua. Single-family house for Vincente Sebastian Llegat
2016
Between 1931 and 1936, the Second Republic in Spain was proclaimed. A social and political model consolidated as one of the most prolific according the artistic point of view. The new democratic regime brought many basic rights for women as the chance to complete their university studies. An emblematic figure of the cultural and architectural revolution of Spain was Matilde Ucelay Maortua. The project here analyzed is the house of Vicente Sebastián Llegat in Pradolargo-Pozuelo de Alarcón, of 1968. Matilde Ucelay designed a building with two levels, a large garden, a swimming pool and the outside porch marking the environment of the L-structure of the house. The critical redrawing of the Uce…
Ermeneutica del segno cinetico. Disegno e danza
2016
Le recenti innovazioni scientifiche e gli studi delle scienze cognitive costituiscono un punto di riferimento per la ricerca artistica che, impiegando diversificate metodologie di interpretazione grafica, si apre verso nuove forme della rappresentazione. L’articolo propone alcune riflessioni sulle implicazioni del movimento in relazione allo spazio architettonico con l’obiettivo di riconoscere nella percezione del movimento, configurazioni bidimensionali che misurano lo spazio restituendo nuove informazioni e rapporti grafici: il peso, il colore, la superficie, il disegno. Recent scientific innovations and studies of cognitive science are a reference point for artistic research, which using…
Nordic subsidiaries in the Baltic States: is model transfer possible?
2011
PurposeThis research seeks to ask to what extent model transfer in employee relations (in terms of employee representation, participation and workplace bargaining) occurs between Nordic and Baltic countries from the principal firm to the subsidiary. It also looks into explanations as to why model transfer occurs – or does not occur – from the perspective of the Nordic industrialist's labour management strategy.Design/methodology/approachThis is a case study comprising three clothing manufacturers and three engineering shops in different Baltic States: Estonia (population 1.4 million), Latvia (2.3 million) and Lithuania (3.4 million). These production sites have headquarters in three Nordic …
Electoral Rules and Proportionality in Spain: Estimating the Impact of some Swedish Rules Through the 2011 Electoral Data
2016
In democratic countries policy making is always framed by many procedures and rules. Some of these rules are particularly critical for allowing more or less proportionality in legislative chambers, though the behavior of political actors also matter. The rules used for technically converting votes into political representatives often exercise such an important role in western countries. In this chapter we provide an estimation of the impact upon proportionality between seats and votes that might have resulted in the 2011 Spanish general elections if some Swedish electoral rules had been applied, ceteris paribus. As we are aware that electoral reforms favouring proportionality may hinder the…
Synthetic individual binaural audio delivery by pinna image processing
2014
Purpose – The purpose of this paper is to present a system for customized binaural audio delivery based on the extraction of relevant features from a 2-D representation of the listener’s pinna. Design/methodology/approach – The most significant pinna contours are extracted by means of multi-flash imaging, and they provide values for the parameters of a structural head-related transfer function (HRTF) model. The HRTF model spatializes a given sound file according to the listener’s head orientation, tracked by sensor-equipped headphones, with respect to the virtual sound source. Findings – A preliminary localization test shows that the model is able to statically render the elevation of a vi…
Annihilators of tensor density modules
2007
Abstract We describe the two-sided ideals in the universal enveloping algebras of the Lie algebras of vector fields on the line and the circle which annihilate the tensor density modules. Both of these Lie algebras contain the projective subalgebra, a copy of sl 2 . The restrictions of the tensor density modules to this subalgebra are duals of Verma modules (of sl 2 ) for Vec ( R ) and principal series modules (of sl 2 ) for Vec ( S 1 ) . Thus our results are related to the well-known theorem of Duflo describing the annihilating ideals of Verma modules of reductive Lie algebras. We find that, in general, the annihilator of a tensor density module of Vec ( R ) or Vec ( S 1 ) is generated by …
