Author Identifcation in Short Texts
No full textMost research on author identification considers large texts. Not many research is done on author identification for short texts, while short texts are commonly used since the rise of digital media. The anonymous nature of internet applications offers possibilities to use the internet for illegitimate purposes. In these cases, it can be very useful to be able to predict who the author of a message is. Van der Knaap and Grootjen [28] showed that authors of short texts can be identified using single words (word unigrams)
with Formal Concept Analysis.
In theory, grammatical information can also be used as an indication of the author of the text. Grammatical information can be captured by word bigrams. Word bigrams are pairs of successive words, so they reveal some information on the sentence structure the author used. For this thesis I performed experiments using word bigrams as features for author identification to determine whether performance increases compared to using word unigrams as features. In most languages many grammatical relations within a sentence are between words that are not successive. The DUPIRA parser, a natural language parser for Dutch, produces dependency triplets that represent relations between non successive words, based on the Dutch grammar. I used these triplets as features, either alone or in combination with unigrams or bigrams. People often use smileys when communicating with someone using digital media.
Therefore, I also examined the influence of smileys on author identification.
The messages used for the experiments are obtained from the subsection `Eurovision Songfestival 2010' of the fok.nl message board. With these messages the data files for 7 feature sets were constructed: word unigrams excluding smileys, word unigrams including smileys, word bigrams excluding smileys, word bigrams including smileys, only dependency triplets, triplets+word unigrams, triplets+word bigrams. A support vector machine algorithm (SVM) was used as the classification method. This is a commonly used algorithm for author identification. There are different implementations of SVM. In this thesis SMO, LibSVM and LibLINEAR are compared. The LibLINEAR algorithm gave the best results.
The results revealed that in all conditions the performance is above chance level. So all reveal some information about the author. The performance for the word unigrams including smileys showed the best results, while the performance using the dependency triplets is the lowest. Results also revealed that when smileys are considered the performance increases, so smileys provide additional information about

Polymer multimode waveguide optical and electronic PCB manufacturing
No full textThe paper describes the research in the £1.3 million IeMRC Integrated Optical and Electronic Interconnect PCB Manufacturing (OPCB) Flagship Project in which 8 companies and 3 universities carry out collaborative research and which was formed and is technically led by the author. The consortium’s research is aimed at investigating a range of fabrication techniques, some established and some novel, for fabricating polymer multimode waveguides from several polymers, some formulations of which are being developed within the project. The challenge is to develop low cost waveguide manufacturing techniques compatible with commercial PCB manufacturing and to reduce their alignment cost. The project aims to take the first steps in making this hybrid optical waveguide and electrical copper track printed circuit board disruptive technology widely available by establishing and incorporating waveguide design rules into commercial PCB layout software and transferring the technology for fabricating such boards to a commercial PCB manufacturer. To focus the research the project is designing an optical waveguide backplane to tight realistic constraints, using commercial layout software with the new optical design rules, for a demonstrator into which 4 daughter cards are plugged, each carrying an aggregate of 80 Gb/s data so that each waveguide carries 10 Gb/s

Riabitare castelli: nuova foresteria in Casa Celli e valorizzazione della connessione tra il Borgo e il Liceo artistico F.A. Grue
No full textLAUREA MAGISTRALEIl progetto “Riabitare Castelli” guarda al borgo come ad una nuova opportunità di ri-abitare, intrecciando memoria, arte e comunità. Il terremoto del 2009 ha segnato profondamente il tessuto urbano e sociale, incidendo sulle dinamiche demografiche e sul legame tra le vecchie e nuove generazioni.
Castelli, celebre per la secolare tradizione della ceramica artistica, trova oggi nella sua arte un valore identitario, preservato e trasmesso dal Liceo Artistico F.A. Grue.
Tra gli obiettivi strategici del Piano di Ricostruzione del 2009 emerge la necessità di riconnettere il centro storico all’istituto d’arte, migliorando l’accessibilità e incentivando un dialogo tra il patrimonio esistente e le nuove generazioni. In quest’ottica, si propone la riqualificazione della “Salita Paradiso”, un percorso che collega il borgo alla scuola.
Nel cuore del centro storico, si propone Casa Celli, attualmente in disuso, come foresteria, in grado di accogliere studenti, artigiani e turisti attraverso un sistema di gestione flessibile e una rotazione stagionale. Da settembre a giugno, ospiterebbe studenti e ceramisti professionisti, generando un ambiente di scambio e sperimentazione artistica. Nei mesi estivi, si aprirebbe invece all’ospitalità turistica, offrendo un’esperienza immersiva nella cultura locale.
Oltre agli spazi abitativi, il progetto valorizza il piano terra come luogo di incontro e condivisione, con laboratori collettivi e ambienti espositivi accessibili all’intera comunità.
Casa Celli si trasforma così in un polo dinamico dove formazione, artigianato e accoglienza si fondono in un modello innovativo di riattivazione della realtà territoriale locale."Riabitare Castelli" project views the village as a new opportunity for re-inhabitation, weaving together memory, art, and community. The 2009 earthquake profoundly impacted the urban and social fabric, affecting demographic dynamics and the bond between older and newer generations.
Castelli, renowned for its centuries-old tradition of artistic ceramics, now finds an identity value in its art, preserved and transmitted by the F.A. Grue Art School.
Among the strategic objectives of the 2009 Reconstruction Plan is the need to reconnect the historic center with the art institute, improving accessibility and encouraging dialogue between existing heritage and new generations. In this perspective, the project proposes the redevelopment of "Salita Paradiso," a pathway connecting the village to the school.
In the heart of the historic center, Casa Celli, currently unused, is proposed as a guesthouse capable of accommodating students, artisans, and tourists through a flexible management system and seasonal rotation. From September to June, it hosts students and professional ceramicists, creating an environment for exchange and artistic experimentation. During summer, it opens to tourism, offering an immersive experience in local culture.
In addition to the living spaces, the project enhances the ground floor as a meeting and sharing place, with collective workshops and exhibition areas accessible to the entire community.
Casa Celli is thus transformed into a dynamic hub where education, craftsmanship, and hospitality merge into an innovative model for reactivating the local territorial reality

The Case Against Redistribution: F.A. Hayek on Social Justice
No full textIn this thesis, F.A. Hayek\u27s argument is against social justice is given context, discussed, and evaluated. Hayek was one of the leading voices of libertarian ideology in the Twentieth Century. While Road to Serfdom is his most popular work, Hayek\u27s philosophy is most fully expressed in his three volume set, Law, Legislation and Liberty. His thoughts against social justice are found the in the second volume, entitled The Mirage of Social Justice. It is the conclusion of the author that Hayek\u27s argument against social justice, in the form of redistribution, falls short as it depends on a presupposition that an evolutionary moral and legal process will necessarily end in securing a libertarian style of government. The only possible means of salvaging the argument would to accept inherent and inviolable human rights, which Hayek fundamentally rejects as he claims the Kantian tradition
La función del juez en el pensamiento de F.A. Hayek
No full textThis paper shows the relationship between the due process and the liberal theory of law of Friedrich Hayek. The author highlights the rules of just conduct in contrast of result rules. The author sustains that Hayek’s theory applies not only to substantive law, but also to adjective law. At the same time, he explains the function of judges in a liberal order in contrast to the activist approach. As a conclusion, the author defends that an adversarial system founded in rules of just conduct is vital for a Free Society, in opposition to an inquisitorial system, or a mixture of them.En este artículo se aborda la relación entre debido proceso y la teoría liberal del derecho de F.A. Hayek, con énfasis en las normas de recta conducta en contraposición a las normas de resultado. Se postula que la teoría de Hayek no sólo es aplicable al derecho sustancial, sino que también al derecho procesal. Al mismo tiempo, se explica la misión del juez en un orden liberal y garantista, contraria a la postura activista del juez. Concluyendo que un sistema acusatorio fundado en normas de recta conducta es indispensable para una Sociedad Libre, en oposición a sistemas inquisitivos o mixtos
MHC immunoevasins: protecting the pathogen reservoir in infection
No full textAlteration of antigen recognition by T cells as result of insufficient major histocompatibility complex (MHC)-dependent antigen-presenting function has been observed in many cases of infections, particularly in in vitro systems. To hide themselves from an efficient immune response, pathogens may act on MHC-related functions at three levels: (i) by limiting the number of potential antigens that can be presented to naive T cells; (ii) by synthesizing proteins which directly affect MHC cell-surface expression; and (iii) by altering the normal intracellular pathway of peptide loading on MHC. Here, we review examples of pathogens' action on each single step of MHC function and we suggest that the result of these often synergistic actions is both a limitation of the priming of naive T cells and, more importantly, a protection of the pathogen's reservoir from the attack of primed T cells. The above mechanisms may also generate a skewing effect on immune effector mechanisms, which helps preserving the reservoir of infection from sterilization by the immune system
