Narratives of Arab Anglophone Women and the Articulation of a Major Discourse in a Minor Literature
“It is important to stress that a variety of positions with respect to
feminism, nation, religion and identity are to be found in Anglophone Arab
women’s writings. This being the case, it is doubtful whether, in discussing this
literary production, much mileage is to be extracted from over emphasis of the
notion of its being a conduit of ‘Third World subaltern women.’” (Nash 35)
Building on Geoffrey Nash’s statement and reflecting on Deleuze and Guattari’s
conceptualization of minor literature and Gloria Anzaldua’s Borderland(s), we
will discuss in this paper how the writings of Arab Anglophone women are
specific minor and borderland narratives within minor literature(s) through a
tentative (re)localization of Arab women’s English literature into distinct and
various categories. By referring to various bestselling English works produced by
Arab British and Arab American women authors, our aim is to establish a new
taxonomy that may fit the specificity of these works
Self-Similar Solutions of Triaxial Dark Matter Halos
We investigate the collapse and internal structure of dark matter halos. We
consider halo formation from initially scale-free perturbations, for which
gravitational collapse is self-similar. Fillmore and Goldreich (1984) and
Bertschinger (1985) solved the one dimensional (i.e. spherically symmetric)
case. We generalize their results by formulating the three dimensional
self-similar equations. We solve the equations numerically and analyze the
similarity solutions in detail, focusing on the internal density profiles of
the collapsed halos. By decomposing the total density into subprofiles of
particles that collapse coevally, we identify two effects as the main
determinants of the internal density structure of halos: adiabatic contraction
and the shape of a subprofile shortly after collapse; the latter largely
reflects the triaxiality of the subprofile. We develop a simple model that
describes the results of our 3D simulations. In a companion paper, we apply
this model to more realistic cosmological fluctuations, and thereby explain the
origin of the nearly universal (NFW-like) density profiles found in N-body
simulations.Comment: corresponds to version published in Ap
Reinforcement Learning for the Unit Commitment Problem
In this work we solve the day-ahead unit commitment (UC) problem, by
formulating it as a Markov decision process (MDP) and finding a low-cost policy
for generation scheduling. We present two reinforcement learning algorithms,
and devise a third one. We compare our results to previous work that uses
simulated annealing (SA), and show a 27% improvement in operation costs, with
running time of 2.5 minutes (compared to 2.5 hours of existing
state-of-the-art).Comment: Accepted and presented in IEEE PES PowerTech, Eindhoven 2015, paper

On non-vanishing and sign changes of the Fourier coefficients of Hilbert cusp forms
In this article, we study (simultaneous) non-vanishing, (simultaneous) sign
changes of Fourier coefficients of (two) Hilbert cusp forms, respectively
