    In 2015, the European Court of Justice established an online “right to be forgotten” in Europe. Under this right to be forgotten, individuals may request that search engines delist links that reference their personal information from search results. Search engines need not grant these requests, but they are now obligated to review them. While the Court\u27s decision to establish the right to be forgotten certainly ignited a debate among Western privacy scholars and policymakers hailing from both sides of the Atlantic, no country has participated in the debate with as much fervor as has France. This thesis addresses the following question: What explains France’s unique sense of urgency with regard to digital right to be forgotten? I argue that French privacy jurisprudence does not sufficiently explain France’s attitude and actions in the right to be forgotten debate, as most scholars have suggested. Rather, extralegal factors – namely, long-established societal mentalités with regard to the modern state\u27s responsibility to shield individuals\u27 honor and reputation from excessive public scrutiny and France\u27s enduring antagonism towards US digital hegemony – bear most of the explanatory weight

    Analysis of seismic pounding of moderate-height RC buildings with aligned slabs

    Collision between adjoining buildings is relevant, since the huge impact forces significantly modify the buildings dynamic behaviour. The separation required by the regulations avoids pounding; however, even in recent buildings, impact can occur due to not fulfilment of codes and seismicity underestimation. Given the importance of this issue, the main objective of this work is to provide efficient simulation tools and to study the relevance of seismic pounding into the most common situations. This work presents a summary of the theoretical developments, discusses the most common simulation software, provides an overview of the previous research, offers recommendations to researchers, and identifies research needs. A new formulation is introduced to estimate the Kelvin-Voigt model damping parameter; it is selected by releasing one of the assumptions of the previous formulations, i.e. considering the influence of the colliding building structures. A simplified parametric study oriented to investigate the performance of the proposed formulation is performed; as well, criteria for selecting their input parameters are provided. Numerical examples on pounding between two multi-storey multi-bay RC buildings are presented, and a shaking table pounding experiment is numerically simulated with the proposed formulation. This Thesis presents a parametrical study on seismic pounding between adjoining short-to-mid height RC framed buildings with aligned slabs. Such condition has been chosen for being highly widespread, mainly in developing countries; two 3 and 5-storey buildings are selected. The buildings are designed for high seismicity. The study consists of analysing the dynamic response of the colliding buildings to a number of representative strong seismic inputs. The inputs are selected based on the soil type and the existence of velocity pulses. Pounding is described by a Kelvin-Voigt linear model; its damping coefficient is derived after the estimated coefficient of restitution by following traditional and more advanced formulations. The behaviour of the buildings is simulated with frame finite element models; nonlinearities are concentrated in plastic hinges located at the ends of each element (concentrated plasticity) whose moment-curvature law is represented by fibre models. Apart from the buildings themselves, the parameters of the study are the soil type, the presence of pulses in the inputs, the damping and stiffness coefficients of the impact model, the separation between the buildings, and the soil-structure interaction. The performance indices are the maximum inter-storey drift, the absolute acceleration and storey shear force, and the cumulated hysteretic energy. The obtained results highlight the relevance of pounding; the influence of the aforementioned parameters is discussed.La col·lisió entre edificis adjacents és rellevant, atès que les enormes forces d'impacte generades modifiquen significativament el seu comportament dinàmic.

Els índexs d'acompliment són: la deriva màxima entre pisos, l'acceleració absoluta i la força de tall a les plantes, i l'energia histerética acumulada.

    The contaminated mine tailings rich in toxic metals pose serious environmental threats to the surrounding areas. The reclamation of these mine sites is an economically costly and technically complex process. Phytoremediation is one of the most promising techniques for sustainable, cost-effective and eco-friendly remediation of contaminated mine sites. Pinus halepensis Mill. was selected due to its special characteristics as a pioneer species growing spontaneously on Campo Pisano (CP) mine tailing, a multiple heavy metal contamination site in SW-Sardinia, Italy. The aim of this PhD thesis is to assess the phytoremediation capability of P. halepensis and focuses on assessing: • the main geochemical and mineralogical characteristics of the soil-plant system through X-ray diffraction (XRD) and scanning electron microscopy (SEM) • Zn,Pb and Cd concentration and its bioavailable fractions in contaminated substrates • the metal accumulation and translocation behaviour in P. halepensis compartments (roots, barks, wood and needles) by calculating the Biological Accumulation Coefficient (BAC), the Translocation (TF) and the Biological Concentration Factors (BCF) • the geochemical forms of Zn, Pb, Cd and their bioavailability through the three-step BCR extraction method in relation to the Physico-chemical and mineralogical characteristics of the soil in-depth and the soil-root system • the phytostabilization potential of seedlings planted under the controlled-greenhouse condition in four different substrates (reference, CP mine tailings, mine tailings amended with compost, mine tailing with their pine and substrates) to evaluate: - the bioavailability of metals and their accumulation in roots and the aerial parts - the plant survival, elongation and biomass production - the mitigation of metal stress in plant by assessing the effectiveness of compost amendment. The outcome of XRD and SEM analysis showed the presence of pyrite, dolomite, calcite, quartz, gypsum and barite with iron sulfate and iron oxide in the polluted substrates. Zn ore minerals and muscovite were mostly detected in the deeper soil layers. Iron sulfate was found mainly in the substrate around the plant roots indicated the presence of some minerals that were discharged in the mine waste and the pyrite dissolution reaction. Zn was the most abundant metal in the substrate as well as plant tissues. The high Zn, Pb and Cd accumulation in the root of P. halepensis reflects the high metal contamination in soil. The BCR analysis showed that the uppermost alkaline-calcareous layers of mine waste were affected by the rich carbonate lithology and mineralogy of CP which were different from the deeper acidic layers. It showed that Pb and Zn were less bioavailable for roots and were often found in the residual fraction, mainly in deep layers of the compost-amended soil, while Cd was found in the exchangeable BCR fraction. The presence of Zn and Pb ore minerals having low solubility, or the rhizosphere interaction processes may cause their resistance to leaching in BCR extraction. The outcome of the greenhouse investigation declared the potential of P. halepensis to tolerate high metal concentrations, and its adaptation to survive in highly contaminated substrates as well as its aptitude to limit metal accumulation and translocation to the aerial parts. The addition of compost enhanced the soil organic carbon and nitrogen contents and restricted the metal bioavailability and accumulation in the aerial parts of plant, however, it didn’t improve the plant survival and growth. These outcomes together with the low biological accumulation and translocation indexes (BCF,TF,BAC<1) for all plant tissues indicated that P. halepensis is an excluder, tolerates high Zn, Pb, and Cd concentrations, restricts their accumulation and translocation to the aerial parts and may be potentially eligible for long-term phytostabilization projects in abandoned mine tailing sites

    New formulation for estimating the damping parameter of the Kelvin-Voigt model for seismic pounding simulation

    Get PDF
    Seismic pounding between adjoining buildings frequently causes serious damage; although collision can be avoided with proper separation, can still occur due to code non-fulfillment, loose requirements of old codes, and seismicity underestimation. Inside this context, this work deals with collision between two buildings with aligned slabs. The simulation of this phenomenon is not obvious, involving stress traveling waves, high-frequency behavior, and local effects. Complex distributed continuum mechanics-based models can be used, but are time-consuming; conversely, the concentrated Kelvin-Voigt model can be utilized instead, being simple and inexpensive, yet accurate. Its behavior is characterized by damping and stiffness parameters; the damping influence is particularly important and a number of estimation criteria have been proposed. Among them, the Anagnostopoulos formulation is simple, and provides satisfactory results in most situations. That formulation consists in estimating the damping parameter after a given target value of the coefficient of restitution; the influence, during impact, of the colliding building structures and the seismic excitation is neglected. This paper proposes an alternative approach that releases one of the aforementioned assumptions: the influence of the building structures and their initial separation is taken into consideration. A simplified parametric study oriented to investigate the performance of the proposed strategy is performed; it is found that the accuracy of the Anagnostopoulos formulation is improved in a number of situations. Noticeably, this gain is obtained at a low computational cost. The proposed formulation is satisfactorily utilized to analyze pounding between two multi-story multi-bay RC buildings and to simulate a shaking table pounding experiment.Peer ReviewedPostprint (author's final draft

    Risk-targeted hazard maps for Spain

    Get PDF
    Many studies have demonstrated that the design of structures in a region through the uniform hazard principle does not guarantee a uniform collapse risk. Even in regions with similar Peak Ground Accelerations (PGAs) corresponding to the same mean return period, the seismic risk in terms of collapse probability will be significantly different mainly due to the shape of the hazard curves as well as uncertainties in structural capacities. In this paper, risk-targeted hazard mapping is being explored in peninsular Spain using a recently updated seismic hazard map. Since risk targeting involves multiple input parameters such as the model parameters of fragility curves, their variability was considered through their probability distribution as observed in reinforced concrete (RC) moment frame buildings, representing the most common building typology in Spain. The influence of the variation of these parameters on the risk results were investigated, and different assumptions for estimating the model parameters of fragility curves are illustrated. These assumptions were included in a fixed (generic) fragility curve or building-site-specific fragility curves. Different acceptable damage states (i.e., collapse and yielding) were considered concerning Spain’s seismicity level. Finally, the maps for risk-targeted design ground motions and risk coefficients are presented. It is outlined that the employment of risk-targeted analysis leads to the modifications for existing design ground motions due to the different shape of the hazard curves across Spain and considering the uncertainty of structural capacity. Moreover, it is found that using the building- and site-specific fragility curves could result in a more uniform seismic risk across the country.The study has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 821046, the Ministerio de Economía, Industria y Competitividad through research project CGL2016-77688-R, with the collaboration and funding provided by Elche and Alicante municipalities
