Non Linear Systems Under Complex α-Stable Le´vy White Noise

2003

The problem of predicting the response of linear and nonlinear systems under Levy white noises is examined. A method of analysis is proposed based on the observation that these processes have impulsive character, so that the methods already used for Poisson white noise or normal white noise may be also recast for Levy white noises. Since both the input and output processes have no moments of order two and higher, the response is here evaluated in terms of characteristic function.Copyright © 2003 by ASME

Non-linear systems under parametric alpha-stable LÉVY WHITE NOISES

2005

In this study stochastic analysis of nonlinear dynamical systems under a-stable, multiplicative white noise has been performed. Analysis has been conducted by means of the Ito rule extended to the case of α-stable noises. In this context the order of increments of Levy process has been evaluated and differential equations ruling the evolutions of statistical moments of either parametrically and external dynamical systems have been obtained. The extended Ito rule has also been used to yield the differential equation ruling the evolution of the characteristic function for parametrically excited dynamical systems. The Fourier transform of the characteristic function, namely the probability den…

Digital Islamophobia: The Swedish woman as a figure of pure and dangerous whiteness

2016

This article addresses the digital culture of Islamophobic bloggers, focusing on the online circulation of a forensic photograph of a Swedish woman who was assaulted. The analysis shows how through appropriating this image, the bloggers created a unifying, imagined whiteness in the transnational Islamophobic network. The empirical analysis clarifies how this one image migrated and transformed in the blogosphere and legitimated the recurrent discursive trope of “Muslim rape.” This image became a subcultural “memory freeze frame” crystallizing the contemporary Islamophobic ideologies articulated in connection to race, ethnicity, nation, gender, and sexuality. The viral circulation of this im…

Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation

2019

In this article, the synthesis by means of the spray pyrolysis method, of the CaMoO4 and rare-earth cation (RE3+)-doped CaMoO4:xRE3+ (RE3+ = Eu3+, Tb3+, and Tm3+; and x = 1, 2, and 4% mol) compounds, is presented. The as-synthesized samples were characterized using X-ray diffraction, Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first-principles calculations, at the density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energie…

Museum coloniality : displaying Asian art in the whitened context

2021

The transformation of Musée Guimet and the transition of museums in the ‘countries of origin’ of its collections elucidates how white-cube crystallises Western cultural hegemony by erasing the colonial past of the objects and by representing the physical form of modernity. It contributes as well to nullifying the demand of repatriation, which seems to merely raise new power struggles rather than to recover indigenous beliefs (or identities). Through such a muséographie, the deities of the Other are ‘elevated’ from ethnographic specimen into art in the West while ‘diminished’ from sacred icons into art or historical artefacts in Asia. Museumification as such constitutes a whitening (Westerni…

Vascular Risk Factors in Mild Cognitive Impairment Subtypes

2007

<i>Background and Aim:</i> To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. <i>Methods:</i> Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. <i>Results:</i> snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and …

Defamiliarizing Blackness and Whiteness in Gloria Naylor’s "Linden Hills"

2018

Gloria Naylor defamiliarizes in Linden Hills (1985) both white and non-white racial categories, in this case blackness and whiteness, both of which emerge as largely performable identities. The defamiliarization of blackness is fairly direct, unfolding mostly through the predominantly negative portrayal of Linden Hills residents and the male line of the Nedeed dynasty, especially Luther Nedeed IV. The defamiliarization of whiteness is mostly indirect, taking place primarily through the exposure of Linden Hills residents’ imitation of whiteness, in particular, the pursuit of what is presented as the negative paradigm of the white materialistic success and the disastrous consequences that ste…

Weiss in der Kunst des 20. Jahrhunderts

2008

This study is dedicated to one color exclusively: the color white. Thus, it provides an important contribution to the history of colors as well as to the meaning and the monochromatic use of white as a means of design in 20th century visual arts. Research is based on the assumption that in order to examine one single color it is not enough to exclusively apply methods thaf are restricted to problems that are intrinsic to the fine arts only. This study is therefore divided into two main sections, which in their methodological approach differ from each other as a matter of principle: the analysis on the phenomenon and the meaning of white as regards its content based relevance is followed by …

Oppressive Faces of Whiteness in Walter Mosley’s "Devil in a Blue Dress"

2018

Walter Mosley’s Devil in a Blue Dress contributes significantly to the literary debate on the definition of whiteness. The socio-historical construction of whiteness emerging from the novel is amplified by white imagery dovetailing with the claims made about white people directly. For the African American first person narrator, Easy Rawlins, living in post-World War II Los Angeles, whiteness mostly spells terror. The oppressive faces of whiteness consist in the following trajectories: property relations, economic exploitation, labour relations, the legal system, different miens of oppressive white masculinity denigrating blackness, spatial dynamics of post-World War II Los Angeles and the w…
