Rafael Moneo: la complessità del vuoto. Dalle matrici formali dell'opera di Oteiza e Chillida

The experience of void, essential to the production of forms and to make use them, can be considered as the base of the activities that attend to the formative processes. If void and matter constitutes the basic substances of architecture. Their role in the definition of form, the symbolic value and the constructive methods of it defines the quality of the space. This job inquires the character of space in the architecture of Moneo interpreting the meaning of the void in the Basque culture through the reading of the form matrices in the work of Jorge Oteiza and Eduardo Chillida. In the tie with the Basque culture a reading key is characterized by concurring to put in relation some of the theoretical principles expressed by Moneo on the relationship between place and time, in an unique and specific vision of the space. In the analysis of the process that determines the genesis of the architecture of Moneo emerges a trajectory whose direction is constructed on two pivos: on the one hand architecture like instrument of appropriation of the place, gushed from an acquaintance process who leans itself to the reading of the relations that define the place and of the resonances through which measuring it, on the other hand the architecture whose character is able to represent and to extend the time in which he is conceived, through the autonomy that is conferred to them from values. Following the trace characterized from this hypothesis, that is supported on the theories elaborated from Moneo, surveying deepens the reading of the principles that construct the sculptural work of Oteiza and Chillida, features from a search around the topic of the void and to its expression through the form. It is instrumental to the definition of a specific area that concurs to interpret the character of the space subtended to a vision of the place and the time, affine to the sensibility of Moneo and in some way not stranger to its cultural formation. The years of the academic formation, during which Moneo enters in contact with the Basque artistic culture, seem to be an important period in the birth of that knowledge that will leads him to the formulation of theories tied to the relationship between time, place and architecture. The values expressed through the experimental work of Oteiza and Chillida during years '50 are valid bases to the understanding of such relationships. In tracing a profile of the figures of Oteiza and Chillida, without the pretension that it is exhaustive for the reading of the complex historical period in which they are placed, but with the needs to put the work in a context, I want to be evidenced the important role carried out from the two artists from the Basque cultural area within which Moneo moves its first steps. The tie that approaches Moneo to the Basque culture following the personal trajectory of the formative experience interlaces to that one of important figures of the art and the Spanish architecture. One of the more meaningful relationships is born just during the years of his academic formation, from 1958 to the 1961, when he works like student in the professional office of the architect Francisco Sáenz de Oiza, who was teaching architectural design at the ETSAM. In these years many figures of Basque artists alternated at the professional office of Oiza that enjoys the important support of the manufacturer and maecenas Juan Huarte Beaumont, introduced to he from Oteiza. The tie between Huarte and Oteiza is solid and continuous in the years and it realizes in a contribution to many of the initiatives that makes of Oteiza a forwarder of the Basque culture. In the four years of collaboration with Oiza, Moneo has the opportunity to keep in contact with an atmosphere permeated by a constant search in the field of the plastic art and with figures directly connected to such atmosphere. It’s of a period of great intensity as in the production like in the promotion of the Basque art. The collective “Blanco y Negro”, than is held in 1959 at the Galería Darro to Madrid, is only one of the many times of an exhibition of the work of Oteiza and Chillida. The end of the Fifties is a period of international acknowledgment for Chillida that for Oteiza. The decade of the Fifties consecrates the hypotheses of a mythical past of the Basque people through the spread of the studies carried out in the antecedent years. The archaeological discoveries that join to a context already rich of signs of the prehistoric era, consolidate the knowledge of a strong cultural identity. Oteiza, like Chillida and other contemporary artists, believe in a cosmogonist conception belonging to the Basques, connected to their matriarchal mythological past. The void in its meaning of absence, in the Basque culture, thus as in various archaic and oriental religions, is equivalent to the spiritual fullness as essential condition to the revealing of essence. Retracing the archaic origins of the Basque culture emerges the deep meaning that the void assumes as key element in the religious interpretation of the passage from the life to the death. The symbology becomes rich of meaningful characters who derive from the fact that it is a chthonic cult. A representation of earth like place in which divine manifest itself but also like connection between divine and human, and this manipulation of the matter of which the earth it is composed is the tangible projection of the continuous search of the man towards God. The search of equilibrium between empty and full, that characterizes also the development of the form in architecture, in the Basque culture assumes therefore a peculiar value that returns like constant in great part of the plastic expressions, than in this context seem to be privileged regarding the other expressive forms. Oteiza and Chillida develop two original points of view in the representation of the void through the form. Both use of rigorous systems of rules sensitive to the physics principles and the characters of the matter. The last aim of the Oteiza’s construction is the void like limit of the knowledge, like border between known and unknown. It doesn’t means to reduce the sculptural object to an only allusive dimension because the void as physical and spiritual power is an active void, that possesses that value able to reveal the being through the trace of un-being. The void in its transcendental manifestation acts at the same time from universal and from particular, like in the atomic structure of the matter, in which on one side it constitutes the inner structure of every atom and on the other one it is necessary condition to the interaction between all the atoms. The void can be seen therefore as the action field that concurs the relations between the forms but is also the necessary condition to the same existence of the form. In the construction of Chillida the void represents that counterpart structuring the matter, inborn in it, the element in absence of which wouldn’t be variations neither distinctive characters to define the phenomenal variety of the world. The physics laws become the subject of the sculptural representation, the void are the instrument that concurs to catch up the equilibrium. Chillida dedicate himself to experience the space through the senses, to perceive of the qualities, to tell the physics laws which forge the matter in the form and the form arranges the places. From the artistic experience of the two sculptors they can be transposed, to the architectonic work of Moneo, those matrices on which they have constructed their original lyric expressions, where the void is absolute protagonist. An ambit is defined thus within which the matrices form them drafts from the work of Oteiza and Chillida can be traced in the definition of the process of birth and construction of the architecture of Moneo, but also in the relation that the architecture establishes with the place and in the time. The void becomes instrument to read the space constructed in its relationships that determine the proportions, rhythms, and relations. In this way the void concurs to interpret the architectonic space and to read the value of it, the quality of the spaces constructing it. This because it’s like an instrument of the composition, whose role is to maintain to the separation between the elements putting in evidence the field of relations. The void is that instrument that serves to characterize the elements that are with in the composition, related between each other, but distinguished. The meaning of the void therefore pushes the interpretation of the architectonic composition on the game of the relations between the elements that, independent and distinguished, strengthen themselves in their identity. On the one hand if void, as measurable reality, concurs all the dimensional changes quantifying the relationships between the parts, on the other hand its dialectic connotation concurs to search the equilibrium that regulated such variations. Equilibrium that therefore does not represent an obtained state applying criteria setting up from arbitrary rules but that depends from the intimate nature of the matter and its embodiment in the form. The production of a form, or a formal system that can be finalized to the construction of a building, is indissolubly tied to the technique that is based on the acquaintance of the formal vocation of the matter, and what it also can representing, meaning, expresses itself in characterizing the site. For Moneo, in fact, the space defined from the architecture is above all a site, because the essence of the site is based on the construction. When Moneo speaks about “birth of the idea of plan” like essential moment in the construction process of the architecture, it refers to a process whose complexity cannot be born other than from a deepened acquaintance of the site that leads to the comprehension of its specificity. Specificity arise from the infinite sum of relations, than for Moneo is the story of the oneness of a site, of its history, of the cultural identity and of the dimensional characters that that they are tied to it beyond that to the physical characteristics of the site. This vision is leaned to a solid made physical structure of perceptions, of distances, guideline and references that then make that the process is first of all acquaintance, appropriation. Appropriation that however does not happen for directed consequence because does not exist a relationship of cause and effect between place and architecture, thus as an univocal and exclusive way does not exist to arrive to a representation of an idea. An approach that, through the construction of the place where the architecture acquires its being, searches an expression of its sense of the truth. The proposal of a distinction for areas like space, matter, spirit and time, answering to the issues that scan the topics of the planning search of Moneo, concurs a more immediate reading of the systems subtended to the composition principles, through which is related the recurrent architectonic elements in its planning dictionary. From the dialectic between the opposites that is expressed in the duality of the form, through the definition of a complex element that can mediate between inside and outside as a real system of exchange, Moneo experiences the form development of the building deepening the relations that the volume establishes in the site. From time to time the invention of a system used to answer to the needs of the program and to resolve the dual character of the construction in an only gesture, involves a deep acquaintance of the professional practice. The technical aspect is the essential support to which the construction of the system is indissolubly tied. What therefore arouses interest is the search of the criteria and the way to construct that can reveal essential aspects of the being of the things. The constructive process demands, in fact, the acquaintance of the formative properties of the matter. Property from which the reflections gush on the relations that can be born around the architecture through the resonance produced from the forms. The void, in fact, through the form is in a position to constructing the site establishing a reciprocity relation. A reciprocity that is determined in the game between empty and full and of the forms between each other, regarding around, but also with regard to the subjective experience. The construction of a background used to amplify what is arranged on it and to clearly show the relations between the parts and at the same time able to tie itself with around opening the space of the vision, is a system that in the architecture of Moneo has one of its more effective applications in the use of the platform used like architectonic element. The spiritual force of this architectonic gesture is in the ability to define a place whose projecting intention is perceived and shared with who experience and has lived like some instrument to contact the cosmic forces, in a delicate process that lead to the equilibrium with them, but in completely physical way. The principles subtended to the construction of the form taken from the study of the void and the relations that it concurs, lead to express human values in the construction of the site. The validity of these principles however is tested from the time. The time is what Moneo considers as filter that every architecture is subordinate to and the survival of architecture, or any of its formal characters, reveals them the validity of the principles that have determined it. It manifests thus, in the tie between the spatial and spiritual dimension, between the material and the worldly dimension, the state of necessity that leads, in the construction of the architecture, to establish a contact with the forces of the universe and the intimate world, through a process that translate that necessity in elaboration of a formal system.

Progetto di reti Sensori Wireless e tecniche di Fusione Sensoriale

Ambient Intelligence (AmI) envisions a world where smart, electronic environments are aware and responsive to their context. People moving into these settings engage many computational devices and systems simultaneously even if they are not aware of their presence. AmI stems from the convergence of three key technologies: ubiquitous computing, ubiquitous communication and natural interfaces. The dependence on a large amount of fixed and mobile sensors embedded into the environment makes of Wireless Sensor Networks one of the most relevant enabling technologies for AmI. WSN are complex systems made up of a number of sensor nodes, simple devices that typically embed a low power computational unit (microcontrollers, FPGAs etc.), a wireless communication unit, one or more sensors and a some form of energy supply (either batteries or energy scavenger modules). Low-cost, low-computational power, low energy consumption and small size are characteristics that must be taken into consideration when designing and dealing with WSNs. In order to handle the large amount of data generated by a WSN several multi sensor data fusion techniques have been developed. The aim of multisensor data fusion is to combine data to achieve better accuracy and inferences than could be achieved by the use of a single sensor alone. In this dissertation we present our results in building several AmI applications suitable for a WSN implementation. The work can be divided into two main areas: Multimodal Surveillance and Activity Recognition. Novel techniques to handle data from a network of low-cost, low-power Pyroelectric InfraRed (PIR) sensors are presented. Such techniques allow the detection of the number of people moving in the environment, their direction of movement and their position. We discuss how a mesh of PIR sensors can be integrated with a video surveillance system to increase its performance in people tracking. Furthermore we embed a PIR sensor within the design of a Wireless Video Sensor Node (WVSN) to extend its lifetime. Activity recognition is a fundamental block in natural interfaces. A challenging objective is to design an activity recognition system that is able to exploit a redundant but unreliable WSN. We present our activity in building a novel activity recognition architecture for such a dynamic system. The architecture has a hierarchical structure where simple nodes performs gesture classification and a high level meta classifiers fuses a changing number of classifier outputs. We demonstrate the benefit of such architecture in terms of increased recognition performance, and fault and noise robustness. Furthermore we show how we can extend network lifetime by performing a performance-power trade-off. Smart objects can enhance user experience within smart environments. We present our work in extending the capabilities of the Smart Micrel Cube (SMCube), a smart object used as tangible interface within a tangible computing framework, through the development of a gesture recognition algorithm suitable for this limited computational power device. Finally the development of activity recognition techniques can greatly benefit from the availability of shared dataset. We report our experience in building a dataset for activity recognition. Such dataset is freely available to the scientific community for research purposes and can be used as a testbench for developing, testing and comparing different activity recognition techniques.

Per un'indagine comparata della relazione voce-movimento nel performer

The present study investigates the principles that effect the relationship between voice and movement in performance. The topic stresses a contemporary tendency, which emerges from the work of numerous artits and looks into a research field that has not yet been well explored. The research arises from what I observed and experienced during my performance practical work and what I deepened after theorical studies: expression through movement and voice reflects constant principles. The first two chapters of the former study analyze the compared lines of the inquiry, from a theoretical point of view (interior and exterior voice-movement spatial patterns, and temporal patterns) and a practical point of view referring to body, action and relation. The third one is a survey on 'vocal gesture' as devised by Francesca della Monica, a topic that finds here the first academic investigation, built after nine years sudies with the artist on the oral sources of her teaching. The research is based on practical and theorical sources (especially philosophical studies of Giovanni Piana, Carlo Serra, Merleau-Ponty; performing studies of Grotowski, Laban, Dalcroze, Tomatis; ancient greek philosophy and literature; bodywork tecqniques as Kineseology, Body-mind centering, Alexander, Feldenkrais). The purpose of the study is to theorize, sistematyze and expose clear lines of compared investigation awakening the performer's interest on a central issue of his work and drawing the researcher's attention to make further focusing on the matter. Abstract (Italian) La ricerca va incontro a una tendenza che la contemporaneità pone in risalto con l'opera di numerosi artisti, investigando un campo ancora poco visitato a livello critico. Essa teorizza, sistematizza ed espone le costanti riscontrate nella relazione tra voce e movimento. L'indagine deriva dal presupposto, a me suggerito dalla pratica e dallo scambio con maestri e performer, e qui approfondito e restituito a livello teorico, che nella danza e nel canto, nell'espressione attraverso il movimento o attraverso la voce, si riflettono gli stessi principi. La tesi è articolata in tre capitoli: i primi due sviluppano le linee di indagine comparata, prima da un punto di vista filosofico e poi da un punto di vista pratico, il terzo porta alla luce il concetto di gesto-vocale come inteso da Francesca della Monica, di cui questo studio rappresenta il primo contributo scientifico, aprendo una ricerca nuova agli studi di settore. Il primo capitolo, 'Risonanze', sviluppa le premesse filosofiche della questione, introduce il corpo come veicolo di voce e movimento, affronta il tema del movimento della voce nello spazio interno del corpo e nello spazio di relazione. Legge poi il movimento in termini temporali, secondo i concetti di istante, ritmo, forma e flusso. Il secondo capitolo, 'Costanti', espone le costanti concrete della relazione voce-movimento in riferimento allo spazio interno del corpo, all'azione, allo spazio esterno di relazione. Il terzo capitolo, 'Confini', analizza il gesto vocale, come inteso da Francesca della Monica, concetto sintesi dell'intera ricerca poiché integra, nella sua essenza, il movimento fisico e vocale, restituendo e approfondendo lo spettro di riflessioni emerse nei primi due capitoli. Il gesto vocale, nella sua accezione espressiva, così come il lavoro di Francesca della Monica, è ancora estraneo agli studi di settore e trova in questo studio un primo contributo accademico. Le fonti sono quelle dell'insegnamento orale di Francesca della Monica, che ho seguito per nove anni, fino a desumerne una mia personale sistematizzazione, integrata con altri punti di vista critici. Analizzo i diversi livelli di profondità del gesto vocale scandendo il tema secondo la categoria della relazione: relazioni motorie, relazioni materiche, relazioni spaziali, temporali, compositive e sinestesiche. Le fonti della ricerca sono scaturite da due sorgenti, quella sul campo, e quella della teoria, confluite qui in un unico flusso. Le fonti 'in presa diretta' sono state avvalorate e confrontate con le fonti relative agli studi di settore (in particolare per la filosofia Giovanni Piana, Carlo Serra, Merleau-Ponty, per il teatro, il canto e la danza Grotowski, Laban, Dalcroze, Tomatis) e le bodywork techniques (Kinesiologia, Body-mind centering, metodo Alexander, metodo Feldenkrais). Ampio spazio viene dato alla grecità antica, che propone sull'espressione di voce e movimento un pensiero integrato carico di speculazioni che racchiudono in nuce i principi sviluppati. Lo studio tenta di offrire un livello di lettura idoneo a suscitare l'interesse del performer, e a valere come momento di indagine per lo studioso, che possa da queste basi operare approfondimenti sulle connessioni proposte. L'obiettivo è restituire la conoscenza, intuita in virtù della pratica, elaborata ed arricchita grazie alla teoria, su un nodo fondamentale per gli studi teatrali e recente oggetto di attenzione da parte di critici e artisti.

Sviluppo, Basi Neurali e Patologie del Sé corporeo

Il presente elaborato ha per oggetto la tematica del Sé, in particolar modo il Sé corporeo. Il primo capitolo illustrerà la cornice teorica degli studi sul riconoscimento del Sé corporeo, affrontando come avviene l’elaborazione del proprio corpo e del proprio volto rispetto alle parti corporee delle altre persone. Il secondo capitolo descriverà uno studio su soggetti sani che indaga l’eccitabilità della corteccia motoria nei processi di riconoscimento sé/altro. I risultati mostrano un incremento dell’eccitabilità corticospinale dell’emisfero destro in seguito alla presentazione di stimoli propri (mano e cellulare), a 600 e 900 ms dopo la presentazione dello stimolo, fornendo informazioni sulla specializzazione emisferica substrati neurali e sulla temporalità dei processi che sottendono all’elaborazione del sé. Il terzo capitolo indagherà il contributo del movimento nel riconoscimento del Sé corporeo in soggetti sani ed in pazienti con lesione cerebrale destra. Le evidenze mostrano come i pazienti, che avevano perso la facilitazione nell’elaborare le parti del proprio corpo statiche, presentano tale facilitazione in seguito alla presentazione di parti del proprio corpo in movimento. Il quarto capitolo si occuperà dello sviluppo del sé corporeo in bambini con sviluppo atipico, affetti da autismo, con riferimento al riconoscimento di posture emotive proprie ed altrui. Questo studio mostra come alcuni processi legati al sé possono essere preservati anche in bambini affetti da autismo. Inoltre i dati mostrano che il riconoscimento del sé corporeo è modulato dalle emozioni espresse dalle posture corporee sia in bambini con sviluppo tipico che in bambini affetti da autismo. Il quinto capitolo sarà dedicato al ruolo dei gesti nel riconoscimento del corpo proprio ed altrui. I dati di questo studio evidenziano come il contenuto comunicativo dei gesti possa facilitare l’elaborazione di parti del corpo altrui. Nella discussione generale i risultati dei diversi studi verranno considerati all’interno della loro cornice teorica.

"Daring to be foolish". L'opera poetica di Robert Kroetsch dal 2001 al 2010

La presente dissertazione si pone come oggetto di analisi la produzione poetica di Robert Kroetsch (1927-2011), scrittore e critico letterario canadese nativo dell’Alberta (Canada), che tra il 1960 e il 2010 ha pubblicato un numero notevole di opere (nove romanzi, più di venti opere poetiche tra componimenti singoli e in raccolta, due volumi di saggi e diverse interviste). In particolare si è scelto di focalizzare l’attenzione sulle ultime tre raccolte di poesia – rispettivamente The Hornbooks of Rita K (2001), The Snowbird Poems (2004) e Too Bad: Sketches Toward a Self-Portrait (2010) – che, se confrontate con la produzione precedente, forniscono prova di alcuni elementi di novità all’interno della prospettiva poetica di Kroetsch. L’ipotesi dalla quale trae origine il presente studio è infatti che, a partire dalla raccolta The Hornbooks of Rita K, Kroetsch abbia imboccato un percorso di evoluzione stilistica che corre in parallelo con la formulazione di una nuova poetica. Nello specifico, si osserva che, negli ultimi dieci anni, da un punto di vista formale i componimenti si frammentano progressivamente, passando da una forma lunga – quella del long poem – a una breve – lo sketch, che risulta più adatta a rappresentare sul piano espressivo una mutata percezione dell’Io poetico. A un simile aspetto si aggiunge poi il fatto che la raffigurazione della propria vicenda umana diventa, con sempre maggiore evidenza, motivo di riflessione su una condizione universale dell’umano e sulla dimensione etica del suo agire.

Technologies for Ambient intelligence: from Smart Objects to Sensor Networks

n the last few years, the vision of our connected and intelligent information society has evolved to embrace novel technological and research trends. The diffusion of ubiquitous mobile connectivity and advanced handheld portable devices, amplified the importance of the Internet as the communication backbone for the fruition of services and data. The diffusion of mobile and pervasive computing devices, featuring advanced sensing technologies and processing capabilities, triggered the adoption of innovative interaction paradigms: touch responsive surfaces, tangible interfaces and gesture or voice recognition are finally entering our homes and workplaces. We are experiencing the proliferation of smart objects and sensor networks, embedded in our daily living and interconnected through the Internet. This ubiquitous network of always available interconnected devices is enabling new applications and services, ranging from enhancements to home and office environments, to remote healthcare assistance and the birth of a smart environment. This work will present some evolutions in the hardware and software development of embedded systems and sensor networks. Different hardware solutions will be introduced, ranging from smart objects for interaction to advanced inertial sensor nodes for motion tracking, focusing on system-level design. They will be accompanied by the study of innovative data processing algorithms developed and optimized to run on-board of the embedded devices. Gesture recognition, orientation estimation and data reconstruction techniques for sensor networks will be introduced and implemented, with the goal to maximize the tradeoff between performance and energy efficiency. Experimental results will provide an evaluation of the accuracy of the presented methods and validate the efficiency of the proposed embedded systems.

A new 3D modelling paradigm for discrete model

Until few years ago, 3D modelling was a topic confined into a professional environment. Nowadays technological innovations, the 3D printer among all, have attracted novice users to this application field. This sudden breakthrough was not supported by adequate software solutions. The 3D editing tools currently available do not assist the non-expert user during the various stages of generation, interaction and manipulation of 3D virtual models. This is mainly due to the current paradigm that is largely supported by two-dimensional input/output devices and strongly affected by obvious geometrical constraints. We have identified three main phases that characterize the creation and management of 3D virtual models. We investigated these directions evaluating and simplifying the classic editing techniques in order to propose more natural and intuitive tools in a pure 3D modelling environment. In particular, we focused on freehand sketch-based modelling to create 3D virtual models, interaction and navigation in a 3D modelling environment and advanced editing tools for free-form deformation and objects composition. To pursuing these goals we wondered how new gesture-based interaction technologies can be successfully employed in a 3D modelling environments, how we could improve the depth perception and the interaction in 3D environments and which operations could be developed to simplify the classical virtual models editing paradigm. Our main aims were to propose a set of solutions with which a common user can realize an idea in a 3D virtual model, drawing in the air just as he would on paper. Moreover, we tried to use gestures and mid-air movements to explore and interact in 3D virtual environment, and we studied simple and effective 3D form transformations. The work was carried out adopting the discrete representation of the models, thanks to its intuitiveness, but especially because it is full of open challenges.
