Writing dialect in Morocco
Artículo en revistaThis article analyzes how Moroccan authors write today in their own dialect.
Publications in Moroccan Arabic are rare: however, it seems that in the last years
the situation is changing and Moroccan writers are beginning to pay more attention
to their mother tongue, a language which allows them to reach better expressivity
and more realism. In this article, an outline is given of the mean orthographic features used byMoroccans when writing in dialect (particularly those diverging from the orthography of Classical Arabic).In order to assure a representative sample,the research published here is basedon data collected from several Moroccan sources of very different kind and printed along a gap of almost forty years
Flat zones filtering, connected operators, and filters by reconstruction
This correspondence deals with the notion of connected operators. Starting from the definition for operator acting on sets, it is shown how to extend it to operators acting on function. Typically, a connected operator acting on a function is a transformation that enlarges the partition of the space created by the flat zones of the functions. It is shown that from any connected operator acting on sets, one can construct a connected operator for functions (however, it is not the unique way of generating connected operators for functions). Moreover, the concept of pyramid is introduced in a formal way. It is shown that, if a pyramid is based on connected operators, the flat zones of the functions increase with the level of the pyramid. In other words, the flat zones are nested. Filters by reconstruction are defined and their main properties are presented. Finally, some examples of application of connected operators and use of flat zones are described.Peer ReviewedPostprint (published version
Quantum vacuum energy and the Casimir effect
Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Any: 2014, Tutor: Joan SolàAn overview of the Casimir e ect is presented. The area of study is historically introduced, together with a basic presentation on the zero-point energy concept in relation with the
quantization of elds. After this, the Casimir force between parallel plates is calculated under two di erent regularization schemes. The brief overview is completed with a compilation of experimental results and implications of the e ect in di erent elds of physics
