Full textNegli ultimi decenni, gli aspetti energetici ed in particolare i consumi di energia legati all’intera vita utile degli edifici sono divenuti oggetto di studio e confronto sia nelle sedi istituzionali di tutto il mondo sia nei dibattiti di una opinione pubblica fortemente sensibilizzata. In quest’ottica si colloca questo lavoro che indaga il comportamento termofisico dei Living Walls, un nuovo tipo di rivestimento vegetale d’involucro direttamente installato sulle facciate degli edifici. Nel primo capitolo viene proposto l’attuale stato dell’arte che offre il panorama della ricerca internazionale sul tema dei rivestimenti vegetali ed in particolare dei Living Walls. Come emerge dalle ricerche effettuate vi sono molti aspetti ancora in fase di studio e conoscenza per i quali sono necessarie valutazioni di tipo teorico e sperimentale. Nel secondo e terzo capitolo vengono introdotte le due principali tipologie di rivestimento d’involucro e vengono ripresi i concetti generali di trasmissione del calore calandoli nello studio dei Living Walls. Vengono inoltre caratterizzati alcuni fenomeni e parametri tipici dei rivestimenti vegetali come l’evapotraspirazione e il Leaf Area Index. Nel quarto capitolo vengono riportati i risultati di due campagne di monitoraggio effettuate su prototipi di Living Walls resi disponibili durante la fase di ricerca. Evidenti sono apparse le interazioni tra il rivestimento e la parete dell’edificio retrostante in termini di temperatura superficiale e flussi di calore. Nel quinto capitolo viene proposto un modello numerico il cui obiettivo è quello di riprodurre il comportamento energetico dei due tipi di Living Wall monitorati. Il modello è stato validato utilizzando i dati delle campagne microclimatiche effettuate sui prototipi. Nel capitolo successivo viene effettuata l’analisi di sensitività del modello considerando le variabili ritenute più significative. Nell’ultimo capitolo viene proposto il calcolo della trasmittanza termica di una parete dotata di Living Wall, attraverso l’utilizzo del modello numerico sviluppato nei capitoli precedenti e i risultati vengono affiancati ai possibili risultati ottenibili con l’utilizzo della normativa attuale. Infine, in Appendice A, viene riportato il codice di calcolo scritto per il modello numerico sviluppato nel quinto capitolo.

Full textIn general, Integer Linear Programming problems are computationally hard to solve. The design of efficient algorithms for them often takes advantage from the analysis of the problem underlying mathematical structure. Starting from the problem of finding the maximum embedded network submatrix of a matrix with entries in {0,−1, 1}, this work deals with the equivalent problem of finding the maximum balanced induced subgraph of a signed graph (mbs, Max Balanced Subgraph). In particular, a new heuristic for the mbs problem, the Cycle-Contraction Heuristic (CCH), has been proposed. The algoritm is based on a graph trans- formation rule that progressively reduces the lengths of cycles, preserving at the same time the feasibility of solutions for the mbs problem. CCH turns out to be more effective of the state-of-the-art heuristics. The efficiency and the effectiveness of CCH can be further improved by means of new rules of data reduction, i.e, by a procedure that simplifies instances and/or decrease their size while preserving the optimal solution of the problem. In the second part of the work, a new exact approach for the mbs prob- lem has been proposed. Such method is based on a polynomial complexity transformation rule that turns a signed graphs into a simple 2-layer graph. The transformation estabilishes a strong connection between mbs and the well- known maximun independent set problem (mis) and allows to resort to a broad spectrum of (exact or heuristic) solution methods proposed in the literature for mis. Finally, the generalized counterpart on signed graphs of some well-known combinatorial problems have been investigated. In particular it has been proven that the k-coloring problem on a signed graph - the generalization on signed graph of the balancing problem and the generalization on a simple graph of the bipartization problem - is equivalent to mis problem on a k-layer graph, i.e., a simple graph obtained by generalizing the 2-layer transformation.

Full textNew scientific discoveries increasingly depend on exceptional devices and research programs. Investments in Research & Development are growing all over the world - according to the UNESCO Science Report 2021 - and more and more concerned those two aspects. The efforts of individual nations fall within the framework of international cooperation to meet the huge costs - both in terms of funds and the number of researchers needed. In this context, the structures dedicated to scientific research - special and unusual plants and equipment - are becoming steadily more important. While they become the fulcrum of scientific activities, they also make their way into the collective imagination of public opinion, animating the debate (regarding both the huge investments and the strategy to manage them) and amazing with the extraordinary results they can achieve. This PhD thesis focuses on the special structures for scientific research, Big Science. They are pretty unknown outside the scientific community, apart from the relative fame of a few of them. Concerning Architecture, this is an unprecedented study. The Big Science species has been investigated here for progressive levels of in-depth analysis, up to the specific study of three structures of global resonance: the Gran Sasso National Laboratories (LNGS), the International Thermonuclear Experimental Reactor (ITER), and the European Organization for Nuclear Research (CERN). The thesis has three parts, marking the methodological approach adopted. The scheme foresees a concise introduction of the context (Part I), the construction of basic knowledge (Part II), and finally, the analytical-critical discussion (Part III). In this way, using the authority principle too, the thesis addresses the programmatic purpose of the thesis - appropriating Big Science, through the process of sublimation of its characters - and develops two scenarios to complete simultaneously continue the research work. The inquiry starts from the evolution of the bond between science and architecture. It is due to the scientific nature of the structures and the architectural character of the research; besides, the two disciplines have significant intersections which are interesting to understand. Therefore, Part I introduces some contextual factors related to Big Science without claiming to be exhaustive. In fact, it was more consistent with the purpose of the thesis to present a series of facts and qualified topics, both following a temporal progression and highlighting transversal topics. The themes dealt with in this initial phase, perhaps less important than the following ones, somehow constitute an applicable constellation to represent the general climate in which the objects of the thesis and their study are inserted. After that, the construction of basic knowledge on the subject takes place within Part II. The path moves forward in progressive stages, deepening specific characteristics. Defined the species called “Big Science,” there is the sampling of thirty cases of remarkable structures, according to a taxonomic approach and thanks to introductory insets. Classifying the leading and most recurrent categories, presented in the most salient features, precedes the collection. Then the study becomes analytical, starting from the definition of three typologies; in fact, there are three typologies identified on the characteristics of the structures - infrastructure, machine, and laboratory. However, the number of typologies of experiences exploring the main structures (LNGS, ITER, and CERN) is also three. Presenting and comparing these experiences allows underlining some circumstances that conditioned the research. In fact, dealing with unpublished circumstances has meant in some way to develop a new approach and, in this sense, to face a challenge of which it may be helpful to give some elements. The concluding chapters of Part II are dedicated to each of the three main case studies for an examination as complete and exhaustive as possible. The final part (III) develops and concludes the work on knowledge and appropriation. It is marked by the process of sublimation of Big Science's structures. It is a way of declining what is known as aestheticization or transfiguration even in the architectural field. The first step is using the authority principle of some Master of Architecture to introduce forms and methods of aestheticization and appropriation of elements and themes previously unrelated to the discipline. Then the experience of space in Big Science is critically analyzed: after clarifying the concept of space, some significant elements and factors from the case studies are linked to the perceptual phenomena. This allows going beyond the simple knowledge of structures, activating a mechanism of appropriation to the field of architecture. Above all, it means triggering the reaction defined as "sublimation": originally the phase transition of a simple substance or a chemical composite from the solid-state to the gaseous state without passing through the liquid state. Here sublimation becomes the analytical-critical method, similarly to the paranoic-critical method of Salvator Dalì, then recalled by Rem Koolhaas. The starting chemical composite is the structures of Big Science, as a solid-state; along with the perception of spatial and aesthetic phenomena, the transition to the gaseous state is ideally achieved. The last chapter suggests two scenarios as the thesis' conclusion. Both represent the completion and, at the same time, the continuation of its aims. The first scenario is the one that ideally closes the chemical process, realizing the inverse sublimation from the gaseous state back to the solid one. It is not possible directly in the context of the thesis. However, it requires a different exercise, as the references to the Masters show: where a process of aestheticization - or even transfiguration - takes place, this does not happen as an analytic-critical fact but involves, ultimately, a project – design or theory. The work of knowledge and appropriation carried out by the thesis provides a material that can crystallize into new aesthetics through the multiple forms of the project. The second scenario sees Big Science in strategic and territorial terms. This approach is latent within the research, but this criticality was found in most of cases considered, even beyond the sampling carried out. The choice to keep this theme in the background wants to put the consistency of Big Science at the center, believing that it is needed to fully appropriate these structures before addressing any strategic-territorial discourse that concerns them. They are a fulcrum at every scale. Therefore, the second scenario represents a further possible fallout of the thesis. In the relationship with the landscape context, operational potentials can be glimpsed. These structures should not be treated as random extras in the territorialization processes but should be born from the idea of becoming an added value of a new landscape also elaborated through them. The nature of this added value passes through the identity of the structures; from the scientific essence to how this took shape and, finally, to how it can be interpreted differently. On a strategic and territorial level, the references to Claude Parent and his work with the Collège des architectes du nucléaire, but also Rino Tami's work for the Ticino motorways, show the potential of a project, including an architectural one, which concerns unexpected fields, possibly even with regulatory repercussions. Therefore, Big Science needs to free itself from the logic of isolation and concealment of machines, without being estranged from the absolute consistency of the structures, which can have, as shown within the thesis, not only a charm but a precise aesthetic value, such as to be able to establish new aesthetics.

Full textIn the last years, the medias and the specialized journals showed an increasing attention to the vibration effects on human body. During my doctoral period I focused the attention on this topic trying to evaluate if mechanical vibration can influence the sportive performance on people with and without disabilities. Every day, our body is exposed to mechanical stimuli such as the vibration produced by the bus we use to go work, or the vibrations generated by the smartphone. The scientific literature agreed in affirming that vibratory stimuli are an effective way to improve motor and neuromuscular skills, by improving the speed of the nerve conduction with a consequent improvement of the muscular stiffness, that play a role in the postural control (Rittweger, 2010). Nowadays, the scientific literature lacks of studies investigating the effects of Whole Body Vibration (WBV) of stabilometric parameters on people with a sensorial disabilities and in particular with a visual disability (Ray, 2008). People with visual impairments does not use visual feedback to adjust their posture, and these persons generally have a sedentary lifestyle that is an important risk factor for several diseases and it is also cause of social interactions reduction. Analysing the literature studies, it is evident the lack of studies investigating the effects of WBV on participants with visual impairment, both sedentary and sportive. This lack of studies, suggested us to design and conduct the pilot study of this thesis that is “Acute effect of Whole Body Vibration (WBV) on postural control in soccer players: a pilot study”. This study aimed to obtain information to design and conduct a preliminary WBV protocol on people without visual impairment in order to evaluate its feasibility and in order to obtain information to use in our subsequent investigations. In this first pilot study, were analysed the differences between amateur soccer players and sedentary coetaneous. The resulted of this pilot study showed that WBV did not significantly alter the postural parameters after acute exposure in both soccer players and sedentary participants. This results allowed to design and conduct the second intervention of this thesis: “Acute effect of Whole Body Vibration (WBV) on postural control in congenially blind subject; a preliminary evidence”. This study compared people with visual impairment vs. people normally sighted. Also this study indicated that WBV did not alter the postural parameters after acute exposure. The results of both these two preliminary intervention, were used to design and conduct the last phase of this thesis, that is the study titled “Acute effect of Whole Body Vibration on balance in blind vs no-blind athletes: a preliminary study” that was recently published in an international peer-reviewed journal. This study compared the effect of WBV exposure on athletes with visual impairment playing Torball vs. normally-sighted athletes playing soccer. Also in this study no significant influences were obtained in both the analysed population. The setting and the WBV methods were the same in all the three studies. Overall, the 3 studies suggested that WBV is a safe and useful method that can be used to improve physical performance also in people with visual disability, due to the absence of side-effects after acute exposure. The WBV can also be used to improve the muscular conditioning of sedentary visual impaired people that do not practice physical activity.

Full textWhat benefits can the historical university libraries, or the university libraries holding special collections, bring to society? To answer this question, it is necessary to investigate the impact of their activities, that is the «difference or change in an individual or group resulting from the contact with library services», according to the definition accepted by ISO 16439:2014. This doctoral thesis tries to suggest a methodology for assessing the impact of the initiatives provided by university libraries in order to enhance such cultural heritage. The study is focused especially on the libraries of Italian universities, also observed from an international perspective thanks to the analysis of non-Italian experiences. After a brief historical outline about university libraries and their commitment to society, the work reflects on the Anglo-American concept of «special collections» and examines the most used methods of enhancement adopted by university libraries. For an overview on the management of heritage in Italian university libraries, the study included a survey addressed to the library systems of Italian public universities. The activities carried out by university libraries may contribute to the cultural development of society, in the perspective of University's Third Mission. In addition to this, the benefits of enhancement can be linked to the concept of «cultural welfare», as well as may promote the value of cultural biodiversity, helping this way to build the peaceful society advocated by the UN 2030 Agenda. The thesis suggests a methodology for evaluating the activities carried out by university libraries to enhance their heritage within the strategic frameworks of Third Mission and 2030 Agenda. To complete the theoretical part of the work, two case studies are presented: one referred to the Biblioteca Històrica de la Universitat de València (Spain) and the other to the University Library of Bologna (Italy).

Full textThe present experimental research study is aimed at investigating the hydraulic performance, sorption capacity as well as the chemical interaction mechanisms, in the short and long term, of different types of cement bentonite mixtures put into contact or permeated with various kinds of sulphate solutions. These CB mixtures are typically used for the construction of cut-off walls to isolate contaminated sites. The investigated sulphate solutions consist of different concentrations of seawater, saline solutions and acidic solutions. These have been selected with the aim of providing valuable scientific and application-oriented insights into the interaction mechanisms and evaluating, in the design phase, the properties of cut-off walls to serve as barriers against the migration of polluted groundwater (or leachates) showing a high concentration of sulphate in solution, or to be employed in marine environment. This study regards traditional cement bentonite mixtures (slag furnace cement and activated sodium bentonite) as well as special mixtures (premixed dry powders), which have been investigated through hydraulic conductivity tests, column tests and batch sorption tests, using seawater, K2SO4 and H2SO4 solutions at different concentrations. The related interaction mechanisms have been analysed also by means of microanalysis instruments, such as XRD, SEM and EDS. The results show that permeation with sulphate solutions can adversely affect the hydraulic performance of cement-bentonite mixtures, mainly because of the formation of gypsum and secondary ettringite. These negative effects on hydraulic conductivity vary according to the sulphate concentration of the solution and the mixture’s hydraulic conductivity, i.e. its composition and aging. Based on the results from this research, a correlation has been set up for assessing the durability of cut off walls depending on the sulphate concentration of the solution. The sulphate concentration, which corresponds to the increase of hydraulic conductivity, has been related to a dimensionless parameter (the critical pore volume), which implicitly takes into account also the permeability of the CB mixture (and therefore its aging). The value of the critical pore volume sets the limit point beyond which the hydraulic efficiency of the mixture (and therefore of the cut-off wall) starts to decrease. The impossibility to reach the critical pore volume for mixtures showing very low hydraulic conductivity from early curing times (despite almost two years of continuous permeation with high hydraulic gradients) confirmed the goodness of the approach. This also points out the importance to select a mixture showing low hydraulic conductivity from early curing times, for limiting the interaction mechanisms between mixture and aggressive solutions, therefore ensuring the cut off wall durability. In this regard, bentonite and clayey fillers eventually present in the mixture play an important role since bentonite does not react with sulphate but contributes to create a less permeable mixture. For K2SO4 solutions, the research proves that batch tests can be a useful method for a preliminary, fast and economical assessment of the interaction between mixtures and sulphate. The sorption capacity of the mixtures respect to sulphate can be modelled using the Freundlich isotherm, also for high concentrations, and corresponds to the sorption capacity calculated through mass balance of the column test data. Referring to solutions of potassium sulphate, the sorption capacity of the mixtures has been studied with reference to K+. The results are well interpolated by linear isotherms and the values of the distribution coefficients is found to be important in terms of migration delay. These values are not affected by the curing time of the mixtures and are in the range established in literature for blast furnace slag cements. It is also possible to model the migration process of K+ using the literature data for the cement paste because the interaction mechanisms are dependent on the presence of cement. The results of the tests conducted using seawater show that the presence in solution of ions potentially reactive to the mixture can affect the hydraulic performance and the durability assessment of a CB mixture, even in presence of a significant sulphate concentration. In particular, no ettringite formation has been detected. Microanalysis highlight the formation of Friedel’s salt resulting from the reaction between chloride ions (Cl-) and calcium aluminate (C3A). This has caused delamination and micro cracking due to the crystallization pressure. Furthermore, Mg++ in seawater has caused leaching of calcium and formation of magnesium hydroxide and magnesium silicate hydrate, which turns into an increment of porosity. Both reactions have resulted in an increment of hydraulic conductivity (2-3 orders of magnitude) on samples permeated with seawater, after only ~1 PV. Also for seawater, the results highlight the possibility to use batch tests for a conservative estimation of CB mixture sorption capacity from early curing time. With reference to the performance and the interaction of CB mixture with acidic solutions, the principal interaction mechanism has been linked to the calcium hydroxide and calcium silicate hydrate washout and a lower production of secondary ettringite, resulting in an increase of hydraulic conductivity. Also in this case a correlation has been set up for durability evaluation of cut off walls in acidic sulphate environment. From a practical point of view, this research has provided important contributions to the design of cut-off walls in sulphate environment, the criteria for the selection of CB mixtures, the preliminary assessment and the identification of the possible interaction mechanisms, the durability evaluation and the migration modelling. This last aspect will be further investigated in future research work.

Full textThe role of the steplength selection strategies in gradient methods has been widely investigated in the last decades. Starting from the pioneering paper of Barzilai and Borwein (1988), many efficient steplength rules have been designed, which contributed to make gradient-based approaches an effective tool for addressing large-scale optimization problems arising in many real-world applications. Most of these steplength selection rules have been developed in the unconstrained optimization framework, with the aim of exploiting some second-order information for achieving a fast annihilation of the gradient of the objective function. These steplength rules have been successfully applied also within gradient projection (GP) methods for constrained optimization, though, in this case, a detailed analysis on how the constraints may affect their spectral properties, as well as their formulation, has not been yet carried out. However, the convergence criteria for the GP method do not require restrictive hypothesis on the steplength parameter, provided that it is bounded away from zero and belongs to a predefined interval: this flexibility in the choice of the steplength allows to develop updating strategies aimed at optimizing the numerical behaviour, possibly in an inexpensive way. Motivated by these considerations, we analyse how, for quadratic programs, the original Barzilai-Borwein (BB) schemes are influenced by the presence of the feasible set. To this aim, we analyse their behaviour with respect to the spectrum of the Hessian of the objective function starting from the simpler case of box-constraints, and then moving to inspect the case of a more general feasible region expressed by a Single Linear equality constraint together with lower and upper Bounds (SLB). We propose modified versions of the BB rules (and their extensions), obtaining improvements of the gradient projection methods. Driven by this study on the BB rules, we extend the spectral analysis to the steplength updating strategy proposed by Roger Fletcher (2012) within the so-called Limited Memory Steepest Descent (LMSD) method. In particular, we combine the idea of the limited memory steplength approach with the gradient projection method for quadratic programming problems subject to box-constraints, investigating the possibility of modifying the original updating strategy in order to take into account the lower and the upper bounds in a suitable manner. The practical effectiveness of the proposed strategies has been tested in several numerical experiments on random large scale box-constrained and SLB quadratic problems, on some well known non quadratic problems and on a set of test problems arising from real-life applications.

Full textIn Myanmar, most parents of disabled children are left critically unprepared while confronting their offspring’s and their own needs. These parents cannot rely on the support from any government agencies, as the country lacks a special educational program for disabled children, as well as a national prenatal screening program. Moreover, in a context where social representations are shaped and influenced by strong religious beliefs (mostly derived from Theravada Buddhism), and by correlated ritual practices such as spirit cults (nats), parents discovering the disability of their newborn children are forced to drastically reconfigure their daily life practices, along with their intimate and social family narratives. As a result of a karmic assumption according to which disability is conceived as “fate” (a punishment for a guilt committed in a past life), or as a preternatural condition related to the taik dimension (world of the spirits), many parents are stigmatized and forced to rehash their family and social relationships. The research is based on an extensive over-one-year-long ethnography in Yangon, which included a series of around 50 interviews with parents of children affected by physical or intellectual impairments. As as result, the thesis examines the parents’ perspectives on disability, as they are influenced by their personal and religious beliefs, and by social expectations and constraints. The dissertation highlights how parents strategically adopt creative practices and discourses in order to cope with different social expectations, within a cultural environment where the defective body is conceived as something to be ashamed of, something that has to be hidden from the public sphere. The ethnographic fieldwork took place mainly at the Eden Centre for Disabled Children (ECDC), and the Mary Chapman School for the Deaf Children, two private schools specifically dedicated to disabled children, who are often unable to attend government schools because of the lack of special educational programs. Both institutions are charities and are located in Yangon, the colonial capital city of former British-ruled colony of Burma, now Myanmar. Besides participant observation and fieldnotes taking, the methodology included open-ended interviews. The single most important gatekeeper for the author to gain access to the fieldwork was an Italian association named Italy-Burma Friendship Association (Associazione per l’Amicizia Italia-Birmania), based in the Northern Italian city of Parma, which the author became a member prior to starting the ethnographic fieldwork in Yangon.

Full textThe “School for the special aids and assistants for disabled children”, opened in 1926 at the Catholic University of Milan by father Agostino Gemelli, was one of the very first in Italy to set up about disabled children teacher training. This School gives evidence of Gemelli’s work in the special education area and also represents the Italian path toward scholastic inclusion for disabled persons. The interest of Gemelli, one of the most famous psychologists in the XX Century Italian framework, towards disability reflects how the contemporary Catholic world cared about interventions for the weakest not only driven by a charity feeling but based on scientific studies. Moreover, the study highlights how teacher training has changed from the Twenties to the Seventies of the last Century, following the different way of looking at disabled children, from isolation in special schools to inclusion in common classes. The thesis contributes to improve Italian studies in the field of the history of special education, a subject that has, for the most part, to be written. The research is carried out through archival investigations with the purpose of shedding light on teachers, users, materials and textbooks of the School, since its origin until the Seventies.

Full textEvery year italian schools dedicate attention and time to the adoption of textbooks. There is a certain degree of rituality in this, in the sense that the choice of a book, while based on strong motivations (also supported by analysis grids and well-organized collegial meetings) is almost taken for granted, obvious. However, only in few countries exists a compulsory adoption of a textbook, medium or instrument that often, in the italian school system, rises to the role of hard core, foundation, permanent center of gravity around which every activities of the class is build. This centrality seems not to be questioned at all, not even in the presence of a certain pressure exerted recently by the technological / digital revolution, which has made available other resources for learning: in many cases these are used as "integrative" compared to the reference text, giving rise to a market in which the publishing houses invest resources in the preparation of digital tools, presented as innovative in support of "normal" textbooks. The adoption of the books is none other than one of the contradictory requests coming from the Italian school system: in fact, if on the one hand the MIUR asks to respond to the differences of each student (he also asks to personalize), on the other hand there is a centralized curriculum that provides for a single path for each student. It is assumed in a sense that everyone should do the same things and hence the use of the only textbook. But if the school world is urged to pay more attention to interpersonal differences (recent legislation regarding pupils with Special Educational Needs), it is implicitly acknowledged that the starting points and growth of each one are different: consequently, it is not said that both the instruments and the final goals must not be. The research, using a historical-documental approach with pedagogical curvature, intends to investigate the potential and the limits of the textbook as regards its accessibility to all the students of the class.

Full textThis research develops from the issues of identify the Special Educational Needs (SEN), which are introduced in Italian schools by the Ministerial Direction of 27 December 2012. The main focus is the broad category of SEN due to "socio-economic, linguistic and cultural disadvantage". This area of need includes the conditions of students, without certification of disability or disturb, who live situations of "scholastic disadvantage". The process of defining and recognizing this type of SEN is extremely delicate and complex: on the one hand it formalises support and valorisation of differences, on the other hand it risks to categorise – and so to exclude – everything that differs form “normality”, trapping difficulties in unproductive labels and classifications. The aim is to explore two different aspects: the psychosocial and cultural dynamics which make teachers identify SENs and the educational and pedagogical effects of this choice. This is why we decided to carry on an exploratory research – in Italian and Maltese scholastic contexts – to investigate teachers’ didactic experiences and perceptions on SEN’s definition and recognition. This allowed us to build up a comprehensive framework of both the identification process of SENs and the educational practices, to this day, implemented in Italian schools.
