Capillary thinning analysis
No full textThe data analysis package is composed of three distinct scripts designed to be run in Matlab with png image files. ContactAngle.m measures the contact angle of a liquid bridge and the spreading distance on the substrate for a series of images during liquid bridge thinning. Startpoint_Symmetry finds the minimum radius for a series of liquid bridge thinning images, identifies the start and end point of thinning, and gives information about the overall symmetry of the trials. EC_binning identifies the fitting region, fits and reports relaxation time for elastocapillary thinning fluids. For all three scripts, an example dataset is provided to demonstrate script functionality.This collection of scripts is a package for analyzing extensional rheology data of liquid bridges. While this was created with Dripping-onto-Substrate datasets, this data analysis package may be useful for other liquid bridge thinning applications such as CaBER. Any pre-processing of images, such as binarizing, converting to png or cropping, can be completed with ImageJ.This material is based upon work supported by the National Science Foundation Graduate Research Fellowship under Grant No. CON-75851, project 00074041.

Esportazione di un modello poetico orientale. L’esempio dello haiku nella letteratura spagnola ultima
No full textAs explained by George Steiner in Nostalgia for The Absolute (1974), after the decline of the formal religious systems and of the major theories-mythologies of the XIX-XX centuries as well (Marxism, Freudian psychoanalysis and Lévy-Straussian anthropology), in Western culture it has appeared a great moral and emotional emptiness. In order to avoid this condition, Western emptiness has often been replaced with “irrational waves” of supernatural concepts as astrology, occultism and Orientalism.
Thanks to this perspective, an Oriental cultural model can be used in Western society and find a new onset in an artistic form such as short poetry (already used in Western literature by the great Latin-American masters José Juan Tablada, Octavio Paz, Jorge Luis Borges and by some of the Spanish poets of the so called Generación del 27). In Spain, in the last decade, thanks to the Eastern model, the haiku, an example of short poetry, has been a recurring model in the youngest poets’ literature but also in their predecessors’ poetry.
The aim of this paper is to present a way among some writings of haiku, that in these last years has become an inevitable model in the exclusive practice and in combination with other poetic forms as well. We will see how poets use haiku in a standard way (the description of a moment of contemplation of nature) but also how they apply haiku’s philosophy to the Western context. Spanish poets as Josep María Rodríguez, Aurora Luque or Manuel Lara Cantizani show how Eastern legacy can gain a greater and greater power, even if, in some cases, its aesthetical-poetical essence has been adapted to the Western Postmodern context that practices it

The bridge: suggestions about the meaning of a pictorial motif
No full textDeveloping research begun at the Warburg Institute in 1983, this paper reflects on the construction of meaning in a work of art, through the analysis of the bridge’s function in painting. It tries to reply to some objections the author received there from Gombrich, about the chance of finding a stable content in the configuration of the bridge. Hence, the study reconsiders the concept of ‘motif’ applied to this structure. In a semiotic perspective a motif is partially independent as regards to a single textual organization, because it has a mobile and migrant feature. However, it is also partially flexible as it depends upon the same organization. The inquiry shows that bridge’s internal structure corresponds to the category of a ‘junction’, with two opposite items, ‘conjunction’ and ‘disjunction’. The development of this theoretical object can be carried out also by figures that are not ‘bridges’, in the natural sense of the word. Furthermore, its meaning does not depend upon the number of examples we can find but only upon their relevance for constructing a ‘grammar of cases’. Differently from the traditional iconographical approach, but also from panofskian iconology, the analysis moves not only towards the simple or complex content of a figure but also towards its description
Ageing and Fatigue Combined Effects on GFRP Grids
No full textMany areas of Europe, especially Italy, Greece, Slovenia and other Balkan States, are generally associated with earthquakes. In the last two decades Fiber Reinforced Polymers (FRP) have gained an increasing interest, mostly for upgrading, retrofitting and repair of masonry and timber structures belonging to the architectural heritage. Recent researches demonstrated that masonry constructions or single structural elements are likely to be effectively repaired or enhanced in their mechanical properties using FRPs. The objective of the research presented in this paper is to study the long-term behavior of composite grids, made of E-CR glass fibers and epoxy-vinylester resin, subjected to harsh environmental factors including fatigue loading and ageing in aqueous solution. The paper presents new original test results on the relationship between the durability and the governing material properties of GFRP (Glass Fiber Reinforced Polymers) grids in terms of tensile strength and axial strains, using specimens cut off from GFRP grids before and after ageing in aqueous solution. The tensile strength of a GFRP grid was measured after conditioning in alkaline bath made by deionized water and Ca(OH)2, 0.16% in weight, solution. The reduction in terms of tensile strength and Young’s modulus of elasticity compared to unconditioned specimens is illustrated and discussed. This degradation indicated that extended service in alkaline environment under fatigue loads may produce reductions in the GFRP mechanical properties which should be considered in design, where cyclic loads and aggressive conditions are prevented in service life
Relative entanglement entropies in 1 + 1-dimensional conformal field theories
No full textWe study the relative entanglement entropies of one interval between excited states of a 1+1 dimensional conformal field theory (CFT). To compute the relative entropy S(ρ1‖ρ0) between two given reduced density matrices ρ1 and ρ0 of a quantum field theory, we employ the replica trick which relies on the path integral representation of Tr(ρ1ρn−10) and define a set of R\'enyi relative entropies Sn(ρ1‖ρ0). We compute these quantities for integer values of the parameter n and derive via the replica limit, the relative entropy between excited states generated by primary fields of a free massless bosonic field. In particular, we provide the relative entanglement entropy of the state described by the primary operator i∂φ, both with respect to the ground state and to the state generated by chiral vertex operators. These predictions are tested against exact numerical calculations in the XX spin-chain finding perfect agreement. © 2017, The Author(s)
Behavioural competences through the outcomes of the IPMA research community
No full textThe model of IPMA about the competences in project management is codified in the IPMA Competence Baseline (ICB). Those competences should be part of the knowledge and know-how of project managers as crucial factors to be effective and competitive. But it is quite common sense that effectiveness and competitiveness in a project require people to be innovative and effective. Behavioural competences are considered as one of the three key areas within the ICB, but surprisingly they seem to be quite neglected among the research community at IPMA World Congresses. A first attempt to analyse to what extent the various competences of the ICB model was done by the author in a paper discussed at the IPMA World Congress 2008; this paper is the continuance of that research, with a more focused interest and with more collected data.
This paper aims also to find which are the main behavioural competences discussed in the papers of the last three IPMA World Congresses and the areas where researchers and practitioners seem to be more trusted in.
This could be the starting point for discussing if the less popular topics (among the ICB 3.0 competences) are really relevant and if they should be considered for being discussed more in detail within the next edition of the ICB. Or conversely if IPMA should be encouraged to study and circulate experiences about them more effectively and frequently
