Modelling the Eddystone Lighthouse response to wave loading
No full textThe Eddystone Lighthouse is an imposing granite structure that has guided mariners through the treacherous waters off the Plymouth coast for nearly 150 years. The General Lighthouse Authorities (GLAs) of the UK and Ireland, recognising the continuing importance of rock-mounted lighthouses as physical aids for navigation, funded a pilot project, commissioning Plymouth University to monitor the tower. The present study aims to provide more information on the structural behaviour of the Eddystone Lighthouse under the impacts from wave loading, through the utilisation of a 3D finite element model. Data from geophones, an offshore wave buoy and video cameras installed on the tower have been used to calibrate and validate the model; in particular, the wave that caused the maximum displacement during the winter 2013/2014 storms has been considered. The point of application of the wave load is important in the
tower’s structural response; the lighthouse being especially vulnerable to larger displacements when the wave acts above its cylindrical base. Finite element analysis suggests that the lighthouse is stable with regard to material failure, and for failure mechanisms of overturning and sliding there are factors of safety of 6.3 and 8.0 respectively. A hypothetical unbroken wave of 17.5 m height would be required to overturn the lighthouse, and one of height 17 m would cause cracking at the base, but in such a location these waves would not be possible
Francisco y los caminos : la traducción de la prosa poética
No full textColección CILAMPALa propuesta que ofrece Montero Raby, se evidencia cómo la autora acude a métodos de carácter hermenéutico para explorar el texto de Amighetti y así identificar aquellos aspectos que resultaban «problemáticos» para el traductor dentro de un texto que se presume como representativo del subgénero prosa poética. Así, la interpretación de las ideas (a veces elididas), de las imágenes y descripciones, de la sintaxis y la puntuación, de las repeticiones léxicas, de las alusiones intertextuales, de la terminología y del lenguaje metafórico, entre otros aspectos presentes en Francisco y los caminos, fue el mecanismo del que Elena Montero Raby echó mano ya no solo para descifrar desde su propia óptica el texto original, sino también para plantear y fundamentar en combinación con un aparato teórico específico sus decisiones a la hora de abordar la traducción de que aquellos rasgos.The proposal offered by Montero Raby shows how the author resorts to hermeneutic methods to explore Amighetti's text and thus identify those aspects that were “problematic” for the translator within a text that is presumed to be representative of the prose-poetic subgenre. Thus, the interpretation of ideas (sometimes elided), images and descriptions, syntax and punctuation, lexical repetitions, intertextual allusions, terminology and metaphorical language, among other aspects present in Francisco y los caminos, was the mechanism Elena Montero Raby used not only to decipher the original text from her own perspective, but also to propose and support, in combination with a specific theoretical apparatus, her decisions when approaching the translation of those features.Escuela de Literatura y Ciencias del Lenguaj

Oscar Wilde : a Victorian sage in a modern age
No full textThis paper assesses Oscar Wilde’s reaction to the fin de siècle and argues against his widely-accepted position as a main figure in the English avant-garde movement, a view which major literary critics such as Peter Gay, Sos Eltis and S. I. Salamensky promote today. Based on Foucault’s definition of modernity as ‘a break with tradition' rather than a specific time, I argue that Wilde was not the modernist author he is widely perceived as, but a conventional Victorian sage who cleverly adopted, and tailored, the fashion of his time to deliver his thoroughly traditional teachings. The paper is split into five sections. The first of deals with Wilde’s creation of his dandy self and the influences of Carlyle, Arnold and Christ over him; the second section examines Ruskin’s influence over Wilde’s theory of art, and Wilde’s self-perception; the third section continues to examine the influence of the Victorian sages on Wilde by exploring his criticism of contemporary modernity in some of his works; the fourth and fifth sections deal with Wilde’s views on the roles of the sexes and his homosexuality respectively, and weigh these views, through further close analysis of his works, against the argument of his modernity. The research ends by asserting that Oscar Wilde was thoroughly Victorian in his views and themes, and that he perceived himself as a sage for his modern age.peer-reviewe
Efficacy of analysis techniques in assessing broken wave loading on a cylinder upon a shoal
No full textEstimation of impulsive wave loading on a cylinder upon a shoal, such as an offshore rock lighthouse constructed on a partially emerged offshore rock with a steep foreshore, poses a unique challenge to marine structural engineers. Large and small scale experimental investigations are the most feasible methods to study this phenomena. However, any experimental investigation with impulsive loading faces challenges in the data analysis, when it is necessary to separate the total impact forces from the force response time series, and to separate the impulsive and quasi-static force components of the total force measurements. This paper is an attempt to re-visit several data analysis techniques with a unique experimental data set to study the advantages and limitations of those techniques, and also to learn how different techniques can be combined into a data analysis methodology to harness maximum information.Accepted Author ManuscriptCoastal Engineerin
Extreme waves, overtopping and flooding at sea defences
No full textThis thesis describes experiments that were carried out using focused wave groups in the UK Coastal Research Facility (UKCRF). Considerable effort was put into calibrating the UKCRF to determine the relationship between the input signals sent to the paddles and the waves generated in the facility. Focused wave groups of various sizes and phases, based on NewWave theory were generated, and measurements were made of the resulting surface elevation data, water particle kinematics, wave runup and overtopping volumes. NewWave theory models the profile of extreme waves in a Gaussian (random) sea. The thesis describes the first time this model has been applied in the context of coastal wave transformation. A method for the separation of the underlying harmonic structure of a focused wave group is described and results presented. This technique has been used in relatively deep water but is shown to work successfully in the coastal zone until wave overturning. A method has been devised to provide a theoretical Stokes-like expansion of the free and bound waves to model the surface elevation and water particle kinematics of the focused wave groups. Satisfactory agreement is achieved between the theoretical predictions of UKCRF measurements. Suggestions are made for an improved model. The underlying harmonic structure of the focused wave groups is presented as stacked time histories that give insight into the wave transformation process from deep to shallow water. Particular attention is paid to the low frequency wave generated as the wave group interacts with the beach. This is compared to the low frequency wave that is generated by a solitary wave in the UKCRF. Runup and overtopping measurements are in reasonable agreement with predictions based on certain empirical formulae, but not others. These comparisons are useful in identifying those formulae able to predict runup and overtopping of extreme waves in the coastal zone

Environmental loading of heritage structures
No full textThis theme issue, featuring Environmental loading of heritage structures, provides a snapshot of current civil engineering approaches to assessing ageing structures under a variety of loads. The publication arose from a serendipitous sequence of interactions. Academics at the University of Plymouth were contacted by Trinity House in 2010 to investigate reported vibrations in their rock lighthouses when impacted by storm waves. A pilot study on the nearby Eddystone lighthouse captured structural response data from the catastrophic storms of 2013/2014 and paved the way for a more comprehensive project. The STORMLAMP project brought together expertise across various civil engineering disciplines, hydrodynamics, field-based structural monitoring and structural modelling, at the University of Plymouth, University of Exeter and UCL, respectively. It has investigated rock lighthouses across all three of the General Lighthouse Authorities of UK and Ireland (Trinity House, Irish Lights and the Northern Lighthouse Board). Field modal testing was undertaken at seven rock lighthouses right across this region to support the characterization of extreme impulsive breaking wave loads, and the identified modal properties have subsequently been used to validate structural models. These models have also required the best estimates of likely wave loads in order to predict maximum structural responses, provided by researchers in the team.Accepted Author ManuscriptCoastal Engineerin
