Framing War and the Nonhuman in Science-Fiction Television: The Affective Politics of V
2020
This article investigates how war between humans and aliens is framed in the original and reimagined versions of the SF television series V and the affective responses and ethical considerations that these frames evoke. Inspired by the work of Judith Butler and Sarah Ahmed and by posthumanist thinking, I analyse how SF television takes part in the cultural formation of “livable lives” for both human and nonhuman beings. It is argued that the kinds of violence that art or the media, including fiction, represent matter for the formation of ethical and political responses to violence. peerReviewed
A Leibniz variety with almost polynomial growth
2005
Abstract Let F be a field of characteristic zero. In this paper we study the variety of Leibniz algebras V ˜ 1 defined by the identity y 1 ( y 2 y 3 ) ( y 4 y 5 ) ≡ 0 . We give a complete description of the space of multilinear identities in the language of Young diagrams through the representation theory of the symmetric group. As an outcome we show that the variety V ˜ 1 has almost polynomial growth, i.e., the sequence of codimensions of V ˜ 1 cannot be bounded by any polynomial function but any proper subvariety of V ˜ 1 as polynomial growth.
La Tene human burial and animal deposit at Varennes-sur-Seine (Seine-et-Marne)
2002
An adolescent was buried at the bottom of a large irregular shaped pit The body that had been lain on one side, legs tucked under, was in the centre of a ring of stones and was covered by a deposit of a dog and four horses of which two were foals and two were young adults. A thick layer of sand and a second deposit of three horses and a dog covered this first deposit. The adolescent skull had been broken and perforated which adds to the distinctiveness of this burial. Most of the horses had been skinned and the tendons had been removed. Also the four legs of one of the horses in the top deposit had been removed. With no datable finds the radiocarbon analysis gives a date corresponding to th…
Multi-domain Features of the Non-phase-locked Component of Interest Extracted from ERP Data by Tensor Decomposition
2020
The waveform in the time domain, spectrum in the frequency domain, and topography in the space domain of component(s) of interest are the fundamental indices in neuroscience research. Despite the application of time–frequency analysis (TFA) to extract the temporal and spectral characteristics of non-phase-locked component (NPLC) of interest simultaneously, the statistical results are not always expectedly satisfying, in that the spatial information is not considered. Complex Morlet wavelet transform is widely applied to TFA of event-related-potential (ERP) data, and mother wavelet (which should be firstly defined by center frequency and bandwidth (CFBW) before using the method to TFA of ERP…
Time - frequency analysis in an open - air theater
2005
Acoustics measurements have been carried out along the steps of an ancient open-air theater. Source positions were fixed in several points in the orchestra while microphones, radially placed, were rotated sector by sector, spatially sampling the cavea. Measurements analysis allowed some speech and music sound quality index calculation for each source-microphone couple. Moving from the observation of acoustic quality indexes a time-frequency analysis of impulse response is presented in this paper. Timefrequency analysis of impulse response gives hints for new considerations about the sound field in this peculiar environment.
Społeczny wymiar nowych mediów. Diaspory narodowe i etniczne jako wspólnoty wirtualne
2020
Współczesne media cyfrowe wyzwalają aktywność użytkowników Internetu współtworzących dyskurs Online sprzyjający konstruowaniu wspólnotowej tożsamości. Szczególnie wyraźnie obserwujemy to w funkcjonowaniu w przestrzeni wirtualnej współczesnych diaspor narodowych i etnicznych, którym nowe media stworzyły warunki do dyskusji i dialogu, wspomagające ponowną integrację i samoidentyfikację. Ważną rolę w tym procesie odgrywa lokalna tradycja kulturowa i pamięć wspólnotowa o folklorystycznym rodowodzie, kreująca regionalną symbolikę każdej diaspory, co zaprezentowano w artykule na przykładzie emigracji żydowskiej z byłego Związku Radzieckiego w Izraelu, polskiej w Stanach Zjednoczonych, skoncentrow…
Ergonomie des documents techniques informatisés : expériences et recommandations sur l'utilisation des organisateurs para-linguistiques
1998
Despite an increasing development, the design of computerized documents is still based on intuitive or esthetics concerns, rather than on experimental evidence. However a large body of literature has investigated the effects of various display factors, both on a perceptual and on a cognitive level. We propose here a review of research and its implication on the design of computerized documents.
Parametric sensitivity of a CFD model concerning the hydrodynamics of trickle-bed reactor (TBR)
2016
Abstract The aim of the present study was to investigate the sensitivity of a multiphase Eulerian CFD model with respect to relations defining drag forces between phases. The mean relative error as well as standard deviation of experimental and computed values of pressure gradient and average liquid holdup were used as validation criteria of the model. Comparative basis for simulations was our own data-base obtained in experiments carried out in a TBR operating at a co-current downward gas and liquid flow. Estimated errors showed that the classical equations of Attou et al. (1999) defining the friction factors Fjk approximate experimental values of hydrodynamic parameters with the best agre…
The two-fluid extended model of superfluid helium
2019
In this paper we perform the first numerical comparison between the two main existing models of superfluid helium: the two-fluid model proposed by Landau and the one-fluid extended model proposed from the extended thermodynamics. The numerical experiments in this paper regard the profiles of the so-called normal and superfluid components in 2D counterflow turbulence.
Valokuva-avusteinen 3D-mallinnus
2017
Kolmiulotteisten mallien käyttötarpeiden lisääntyessä on kehitelty erilaisia menetelmiä tuottaa niitä reaalimailman esineistä valokuvia apuna käyttäen. Tämän kandidaatintutkielman tarkoitus on kuvailla erilaisia menetelmiä aina manuaalisista täysin tietokoneavusteisiin. Due to increased demand for three-dimensional models, various methods have been developed to produce them based on real-world objects with the help of photographs. The main goal of this study is to describe such methods.
