Les référendums sur la souveraineté de l'Écosse et de la Catalogne : le renvoi relatif à la sécession du Québec en comparaison

L’année 2014 est marquée par les référendums sur la souveraineté de l’Écosse et de la Catalogne, deux nations partageant de nombreux points communs sur les plans de l’histoire et de la culture. Le cadre juridique pré-référendaire de chacune de ces régions est fondamentalement le même: l’existence juridique de l’Écosse et de la Catalogne est directement issue de la volonté d’un État central unitaire, respectivement le Royaume-Uni et l’Espagne. La compétence législative de tenir un référendum sur l’autodétermination de ces régions est d’ailleurs ambiguë. Devant ce dilemme, le Royaume-Uni permet à l’Écosse d’organiser un référendum sur sa souveraineté. Il en résulte un processus démocratique juste, équitable, décisif et respecté de tous. De son côté, l’Espagne interdit à la Catalogne d’en faire de même, ce qui n’empêche pas Barcelone de tout mettre en œuvre afin de consulter sa population. Il en découle un processus de participation citoyenne n’ayant rien à voir avec un référendum en bonne et due forme. 20 ans après le dernier référendum sur la souveraineté du Québec, l’étude des référendums de l’Écosse et de la Catalogne nous permet de mettre en lumière la justesse, mais aussi l’incohérence partielle des enseignements de la Cour suprême du Canada dans son Renvoi relatif à la sécession du Québec. D’un côté, la nécessité d’équilibrer les principes constitutionnels sous-jacents de démocratie et de constitutionnalisme est mise en exergue. Parallèlement, les concepts de question et de réponse claires, d’effectivité et de négociations post-référendaires prennent une toute autre couleur face à un nouvel impératif absent des conclusions de la Cour suprême : celui des négociations pré-référendaires.

Influence of cutting parameters and tool wear on martensitic stainless steel surface integrity after a face milling process

Surface finish is one of the most relevant aspects of machining operations, since it is one of the principle methods to assess quality. Also, surface finish influences mechanical properties such as fatigue behavior, wear, corrosion, etc. The feed, the cutting speed, the cutting tool material, the workpiece material and the cutting tool wear are some of the most important factors that affects the surface roughness of the machined surface. Due to the importance of the martensitic 416 stainless steel in the petroleum industry, especially in valve parts and pump shafts, this material was selected to study the influence of the feed per tooth and cutting speed on tool wear and surface integrity. Also the influence of tool wear on surface roughness is analyzed. Results showed that high values of roughness are obtained when using low cutting speed and feed per tooth and by using these conditions tool wear decreases prolonging tool life.

Resonance Energy Transfer-Based Molecular Switch Designed Using a Systematic Design Process Based on Monte Carlo Methods and Markov Chains

A RET network consists of a network of photo-active molecules called chromophores that can participate in inter-molecular energy transfer called resonance energy transfer (RET). RET networks are used in a variety of applications including cryptographic devices, storage systems, light harvesting complexes, biological sensors, and molecular rulers. In this dissertation, we focus on creating a RET device called closed-diffusive exciton valve (C-DEV) in which the input to output transfer function is controlled by an external energy source, similar to a semiconductor transistor like the MOSFET. Due to their biocompatibility, molecular devices like the C-DEVs can be used to introduce computing power in biological, organic, and aqueous environments such as living cells. Furthermore, the underlying physics in RET devices are stochastic in nature, making them suitable for stochastic computing in which true random distribution generation is critical.

In order to determine a valid configuration of chromophores for the C-DEV, we developed a systematic process based on user-guided design space pruning techniques and built-in simulation tools. We show that our C-DEV is 15x better than C-DEVs designed using ad hoc methods that rely on limited data from prior experiments. We also show ways in which the C-DEV can be improved further and how different varieties of C-DEVs can be combined to form more complex logic circuits. Moreover, the systematic design process can be used to search for valid chromophore network configurations for a variety of RET applications.

We also describe a feasibility study for a technique used to control the orientation of chromophores attached to DNA. Being able to control the orientation can expand the design space for RET networks because it provides another parameter to tune their collective behavior. While results showed limited control over orientation, the analysis required the development of a mathematical model that can be used to determine the distribution of dipoles in a given sample of chromophore constructs. The model can be used to evaluate the feasibility of other potential orientation control techniques.

DEVELOPMENT OF A MECHANISM AND PROCESS TO CONTINUOUSLY PRODUCE SPHERICAL, TORREFIED BIOMASS PELLETS

A recently developed novel biomass fuel pellet, the Q’ Pellet, offers significant improvements over conventional white pellets, with characteristics comparable to those of coal. The Q’ Pellet was initially created at bench scale using a proprietary die and punch design, in which the biomass was torrefied in-situ¬ and then compressed. To bring the benefits of the Q’ Pellet to a commercial level, it must be capable of being produced in a continuous process at a competitive cost. A prototype machine was previously constructed in a first effort to assess continuous processing of the Q’ Pellet. The prototype torrefied biomass in a separate, ex-situ reactor and transported it into a rotary compression stage. Upon evaluation, parts of the prototype were found to be unsuccessful and required a redesign of the material transport method as well as the compression mechanism. A process was developed in which material was torrefied ex-situ and extruded in a pre-compression stage. The extruded biomass overcame multiple handling issues that had been experienced with un-densified biomass, facilitating efficient material transport. Biomass was extruded directly into a novel re-designed pelletizing die, which incorporated a removable cap, ejection pin and a die spring to accommodate a repeatable continuous process. Although after several uses the die required manual intervention due to minor design and manufacturing quality limitations, the system clearly demonstrated the capability of producing the Q’ Pellet in a continuous process. Q’ Pellets produced by the pre-compression method and pelletized in the re-designed die had an average dry basis gross calorific value of 22.04 MJ/kg, pellet durability index of 99.86% and dried to 6.2% of its initial mass following 24 hours submerged in water. This compares well with literature results of 21.29 MJ/kg, 100% pellet durability index and <5% mass increase in a water submersion test. These results indicate that the methods developed herein are capable of producing Q’ Pellets in a continuous process with fuel properties competitive with coal.

Polymer Process Partitioning: Extruding Plastic Pipe

When plastic pipe is solidified, it proceeds through a long cooling chamber. Inside this chamber, inside the hollow extrudate, the plastic is molten, and this inner surface solidifies last. Sag, the flow due to the self-weight of the molten plastic, then happens in this cooling chamber, and sometimes, thickened regions (called knuckles) arise in the lower quadrants, especially of large diameter thickwalled pipes. To compensate for sag, engineers normally shift the die centerpiece downward. This thesis focuses on the consequences of this decentering. Specifically, when the molten polymer is viscoelastic, as is normally the case, a downward lateral force is exerted on the mandrel. Die eccentricity also affects the downstream axial force on the mandrel. These forces govern how rigidly the mandrel must be attached (normally, on a spider die). We attack this flow problem in eccentric cylindrical coordinates, using the Oldroyd 8-constant constitutive model framework. Specifically, we revise the method of Jones (1964), called polymer process partitioning. We estimate both axial and lateral forces. We develop a corresponding map to help plastics engineers predict the extrudate shape, including extrudate knuckles. From the mass balance over the postdie region, we then predict the shape of the extrudate entering the cooling chamber. We further include expressions for the stresses in the extruded polymer melt. We include detailed dimensional worked examples to show process engineers how to use our results to design pipe dies, and especially to suppress extrudate knuckling.

Jewish legal regulation documents from Lucena in the 11th century

The aim of these pages is to offer a view on the Jewish regulation of Lucena (Cordoba) in the 11th century. Through the legal texts originating from this place, which were conserved in the Cairo Genizah and later guarded at the Bodleian Library in Oxford, it is possible to observe the legal procedure of this group in relation to two essential issues: its consideration of dhimmis, due to its belonging to the ’ahl al-Kitāb or ‘people of the Book’ category, and the internal regulation of the community according to the problems emerged in it. In this article, therefore, the more frequent legal matters derived from the litigations conserved from this city until these dates will be studied.

Phraseological Binomials: A Proposal for Equivalences in English-Spanish Legal Translation

Phraseological units are complex structures that may be difficult to comprehend and transfer into other languages due to their idiomatic nature. The translator of English legal texts often comes across binomials, a type of phraseological unit that is a characteristic of this specialized discourse. Based on a specialized comparable bilingual corpus composed of legal forms and agreements, this article identifies several occurrences of this phraseological structure and extracts the most frequent examples in English and Spanish. A contrastive analysis of the data obtained from the corpus helps to establish a series of equivalencies among binomials in both languages and proposes a typology of equivalences regarding these phraseological structures.

Circular migration and the Internet: The role of social networks in the sociocultural context of Mexican residents in Barcelona

This work focuses on the study of the circular migration between America and Europe, particularly in the discussion about knowledge transfer and the way that social networks reconfigure the form of information distribution among people, that due to labor and academic issues have left their own country. The main purpose of this work is to study the impact of social media use in migration flows between Mexico and Spain, more specifically the use by Mexican migrants who have moved for  multiple years principally for educational purposes and then have returned to their respective locations in Mexico seeking to integrate themselves into the labor market. Our data collection concentrated exclusively on a group created on Facebook by Mexicans who mostly reside in Barcelona, Spain or wish to travel to the city for economic, educational or tourist reasons.  The results of this research show that while social networks are spaces for exchange and integration, there is a clear tendency by this group to "narrow lines" and to look back to their homeland, slowing the process of opening socially in their new context.

Relanzando la Respuesta Rápida Militar: Los Battlegroups

La utilidad de los Battlegroups, casi una década después de declarar capacidad operativa plena, ha estado y continuará estando en duda debido a la inacción europea. Para que la UE se convierta en el actor internacional que durante tantos años ha proclamado, necesitará consolidar su capacidad de respuesta rápida militar para hacer frente a crisis multidimensionales y llevar a cabo todo el espectro de Misiones Petersberg. El artículo hace un repaso a la concepción y el desarrollo de los Battlegroups y propone un conjunto de reformas para que puedan llegar a ser un instrumento efectivo de respuesta rápida militar.

Time series wind power forecasting based on variant Gaussian process and TLBO

Due to the variability and stochastic nature of wind power system, accurate wind power forecasting has an important role in developing reliable and economic power system operation and control strategies. As wind variability is stochastic, Gaussian Process regression has recently been introduced to capture the randomness of wind energy. However, the disadvantages of Gaussian Process regression include its computation complexity and incapability to adapt to time varying time-series systems. A variant Gaussian Process for time series forecasting is introduced in this study to address these issues. This new method is shown to be capable of reducing computational complexity and increasing prediction accuracy. It is further proved that the forecasting result converges as the number of available data approaches innite. Further, a teaching learning based optimization (TLBO) method is used to train the model and to accelerate
the learning rate. The proposed modelling and optimization method is applied to forecast both the wind power generation of Ireland and that from a single wind farm to show the eectiveness of the proposed method.

A Novel Methodology to Characterize the Constitutive Behaviour of Polyethylene terephthalate for the Stretch Blow Moulding process

The stretch blow moulding (SBM) process is the main method for the mass production of PET containers. And understanding the constitutive behaviour of PET during this process is critical for designing the optimum product and process. However due to its nonlinear viscoelastic behaviour, the behaviour of PET is highly sensitive to its thermomechanical history making the task of modelling its constitutive behaviour complex. This means that the constitutive model will be useful only if it is known to be valid under the actual conditions of interest to the SBM process. The aim of this work was to develop a new material characterization method providing new data for the deformation behaviour of PET relevant to the SBM process. In order to achieve this goal, a reliable and robust characterization method was developed based on an instrumented stretch rod and a digital image correlation system to determine the stress-strain relationship of material in deforming preforms during free stretch-blow tests. The effect of preform temperature and air mass flow rate on the deformation behaviour of PET was also investigated.
