Nota sul Silio 'politico' negli epigrammi di Marziale
No full textIn Martial’s epigrams Silius Italicus is portrayed as a man of learning, author of the Punica and admirer of Vergil’s works, but also as a public figure and a former consul of Rome. My paper focuses on the epigrams devoted to the ‘political’ Silius, and suggests to relate them mainly to a certain stage in Silius Italicus’ life and to a specific communication strateg
La lima e il testo da Ovidio a Marziale: poetica e comunicazione
No full textIn the poetic texts from the Imperial age (from exiled Ovid to Martial and Statius) the metaphor of poetic lima undergoes
a deep transformation: the lima is no longer in the hands of the poet, who polishes his verses for years and years, but
(often) in those of a cultivated patron, requested by the author to correct the book before publication.
In the Flavian age the lima is then placed within the complex communication system of literary patronage, where it
becomes an element of homage and compliment. However, the metaphor never loses its original poetological meaning:
both Martial and Statius use it differently, in relation to themselves and in relation to intellectual patrons, thus subtly
reaffirming their own different and higher commitment to literature
Un'idea di Marziale : a proposito di un recente commento al V libro degli epigrammi
No full textThe article discusses some aspects of the fifth book of Martial's epigrams, starting from the new commentary by A Canobbio (Naples 2011). The structure of the book's prefatory section (epigr. 1-20) is particularly interesting because it creates a complex strategy of communication to the audience princepy, patrons, anonymous lector) and of self-fashioning of the author. The intertextual relationship with poetic authorities of the Augustan age, especially Horace and Ovid, is strongly present here while in the corpus of the book the dialogue with Catullus and the theater of Plautus becomes more evident - As Canobbio shows in relation to the 'cycle' of the subsellia. The fifth book proves to be a complex poetic text which enacts a multi-level dialogue with the Roman public and with the Latin literary tradition

Author’s main reason for choosing the topic is the work relationship with Digitrükk OÜ on the purchasing and logistics spetcialist position and motive of analyzing the interest of the company's inventory management and purchasing processes as the current systems have become ineffective due to development of the company and their development has not been sufficiently addressed. At the beginning of the thesis, the author set the research task, which was to develop a case study methodology, conduct a study and develop improvement proposals. The work revealed that the main problem was the lack of concentration of the company on stock management problems. During the study, the tasks were answered and the proposals for improvement were submitted. The author hopes that the final thesis will help the company's management to solve the problem of stock management, thus increasing the company's competitiveness, productivity, customer satisfaction, as well as decreasing production costs and achieving the development goals set in the 2016 development plan
Stability of wide-graded rubble mounds
No full textThe reshaping of temporary rubble mounds like the core of breakwaters or reclamation bunds is often a concern for contractorsi n the construction stages of marine structures. The formulas found in literature for the prediction of such behavior are few, and they do not provide clear insight on the influence of relevant parameters, in particular the small dimensions and wide stone-size gradation of the material involved, usually consisting of quarry run or resulting from dredging. The previous research in the field of dynamic stability focused on berm breakwaters and gravel beaches. These two typologies of structures define the range to which the rubble mounds considered in this study generally belong. An overview on the design tools provided by the technical literature shows that, whenever the grading was included as a governing parameter, some influence was recognized in the characteristics of the structure (e.g. the permeability) and in the dynamism of the different fractions of stone sizes. However, very wide ranges of the parameter grading were never investigated and a specific analysis in this direction constitutes the main significance of this study. The Delft University of Technology provided the laboratory facilities to carry out physical model tests on a wide graded rubble mound structure representative of the core of a breakwater. The parameter D85/D15, describing the stone-size gradation of the construction material, was varied between the values 2.71 and 17.7, and two different seaward slopes of the model structure were also tested. The reshaped cross-shore profiles measured during the tests showed how if the grading increases the stability of the structure is reduced. This is not always in accordance with the findings of previous researchers, showing how the extrapolation of existing empirical formulas to structures with high values of the ratio D85/D15 do not give reliable results. Instead, the formulas given by van de Meer (1992) to estimate the whole reshaped profile of a dynamic slope predict with good agreement the shape of the measured profiles, although the physical model shows a larger horizontal extension of the displacements. This difference is governed by the grading, being more noticeable as this parameter increases. This result leads to the definition of new formulas, some of them being modifications of the ones given by van der Meer, to describe the geometry of a reshaped profile. The formulas, all including the parameter grading, are derived through curve fitting of the measured data. Also a formula for the direct estimation of the crest recession is given. As a final step, a simple numerical model is proposed in which the new formulas are implemented, constituting a quick way to assess the shape of a slope after a wave attack. As a suggestion for further utilization of the results of physical modeling, a brief comparison is also carried out between the output of the tests and the prediction of the numerical model XBeach (developed mainly at UNESCO-IHE). In conclusion, this research points out how the formulas provided by the technical literature are not reliable in representing the effects of a very wide stone-size gradation in the stability of a rubble mound structure. Physical model tests proved to be a suited way to investigate these effects, as the nature of the phenomena who play a role in the stability does not allow a simple analytical representation. The tests carried out within the present study lead to the implementation of a numerical model of practical use for engineers and contractors: further investigations through laboratory tests are recommended to validate and extend the findings of this study. Another proposed direction for further research is the comparison between the results of physical model tests and the output of numerical models.Hydraulic EngineeringCivil Engineering and Geoscience
Martial between Rome and Bilbilis
No full textThis article traces and synthesizes the complex representation of
the motif city-countryside in Martial’s epigrams, taking into account
its different, sometimes contradictory, aspects. These aspects, so far
looked at either out of context or only within the framework of single books, are brought together and, above all, are seen in their different functions (especially the self-fashioning of the author)
and diachronic development.
Section 2 starts from Epigram1.49 to demonstrate the
fluctuating evaluation of the appropriateness or otherwise of a life
in the city or countryside, depending on one’s age, the alternation
of one’s activities or perspective (patron or poet). Section 3 explores
the tension between fond ideas of leaving the city behind and the
‘reality’ of being in provincial surroundings, unconducive to poetry,
where positive evaluations of the countryside are lacking. In section
4, I explore Books 4–9 where otiumis sometimes situated in an urban
context, while the opposition to life in the countryside recedes into
the background. In so far as the relationship between city and coun-
tryside plays a role, they are harmonious. By contrast, Book 10
returns to the motifs encountered in Books 1–2, but here they become
more complex and problematic as they are linked to Martial’s move
from Rome to Celtiberia (section 5). In Book 12, as earlier in Book
3, the dominant opposition is that between Rome and not-Rome
(section 6). I conclude that the picture of a Martial constantly and
consistently dreaming of a countryside existence must be adjusted:
the depiction of city and countryside is not constant over the course
of Books 1–12 but changes in accordance with the construction of
the poet’s identity and his history within the text

Validation and application of three-dimensional auralisation during concert hall renovation
No full textDuring the renovation of auditoria and concert halls, the acoustic quality is normally evaluated from measurements of impulse responses. One possibility for evaluating the acoustic quality from the measurements (the simulations) consists of convolving anechoic music with the measured (or simulated) impulse responses. In this way, a psycho-acoustic test is achieved using a virtual sound field representation. The listening room ‘Arlecchino’ at the University of Bologna includes ambisonics (up to fifth order) and stereo-dipole playback for virtual reproduction of sound in rooms. In this article, the effectiveness of the listening room ‘Arlecchino’ is first analysed, comparing acoustic parameters obtained from binaural impulse responses measured in some opera houses (in Italy) and auditorium (in Japan) with those virtually measured after the virtual reconstruction obtained in the listening rooms. The similarity between real and virtual sound fields, has been evaluated by comparing different acoustic parameters calculated by real and virtual sound fields, in four halls in different configurations, by means of the stereo-dipole method. In the second part of the article, the listening room was used to analyse the variation in interaural cross-correlation measurements in rooms obtained considering different anechoic sound signals convolved with the binaural impulse responses, to quantify the variation of the interaural cross correlation with different motifs. For this purpose, two different musical instrument digital interface musical motifs, very different from each other for their music characteristics, have been considered. Moreover, for each musical motif, different sound characteristics (i.e. different musical instruments) were considered, to consider both the rhythmic and timbre aspect
A Psycho-Acoustical Experiment Using a Stereo Dipole for Spatial Impression of Music Signals
No full textAcoustic performance of concert halls and opera houses is usually assessed by measuring the BIRs (Binaural Impulse Responses). Anechoic music convoluted with BIRs constitutes the virtual sound in the way it is played in the sound field, i.e. the room. From BIRs, the IACC (Inter-Aural Cross Correlation) can be computed. This parameter makes it possible to evaluate the spaciousness of the hall. However, the calculation of the IACC value is affected by the convolution technique used as well as the kind of musical motif. For example, in the same concert hall, the BIR provides three different IACC values in the case of three different motifs played in it. This study has conducted a psycho-acoustic experiment by using a virtual sound field representation produced by the stereo dipole technique in a listening room. In the experimental set-up there were two or four loudspeakers, corresponding to the single stereo-dipole or the dual stereo-dipole, respectively. By cancelling the cross-talk pathways (i.e. from left loudspeaker to right ear), the parallel sound presentation creates a 3D sound field for listeners sitting in the target point. The invert Kirkeby method was adopted to determine the inverse filters. Finally, the auralization technique with measured BIRs in theatres was utilized and the virtual sound field was generated in the Arlecchino listening room (Bologna, Italy), a low reverberation room equipped with an Ambisonic system. In the virtual sound field, the BIR was recorded again by the same dummy head used during the measurement in the theatres. The similarity between real and virtual sound fields was evaluated by comparing some acoustic parameters. The stereo-dipole technique demonstrates a good degree of accuracy of the sound field appearance. Moreover, the accuracy of the sound field appearance was analysed using two musical motifs and three musical instruments, comparing the values of the IACC calculated by echoic music with the virtual echoic music.Building Physic
