Presupposti ed obiettivi dell’innovazione nel contesto-scuola: dalla comunità al bene comune
No full textThe aim of the research was to question the meaning of innovation, trying to transcend the mere size methodological and instrumental. On the basis of the philosophical and pedagogical concept of formativity, we have questioned the assumptions and objectives of innovation, through a reading ethic and hermeneutics of educational planning.The research was conducted on the transverse planes: the theoretical analyzes in sociopedagogical perspective the relationship school-society, relying on theoretical principles of neopersonalismo Christian-based and relational paradigm; on the practical uses of an experimental educational-training activities started in 2011 in the municipality of Montecorvino Pugliano (Salerno).The hypothesis of the project relates to the revaluation of the concept of community within the school situation: the social capital is and must be first of all human capital, so that “ the us become internalized and deep root, able to make fruitful the common good” (Castaldi M.C, 2013).It outlines the objectives of the project: “once again on” the relational being of man; rediscover the ontological significance of the community dimension of the school experience; form the humus made of human values and common feelings.The educational-training methodologies used are part of the perspective of the pedagogy of the gift, articulating a virtuous circle between the education of thought (John Dewey) and the education of the heart (St. John Bosco).Scopo della ricerca è stato quello di interrogarsi sul senso dell’innovazione, cercando di trascenderne la sola dimensione metodologico-strumentale. Sulla scorta del concetto filosofico-pedagogico di formatività ci si è interrogati sui presupposti e sugli obiettivi dell’innovazione, attraverso una lettura etico-ermeneutica della progettualità educativa.La ricerca si è svolta su due piani trasversali: sul piano teorico analizza in prospettiva socio-pedagogica la relazione scuola-società, poggiando sui principi teorici del neopersonalismo di ispirazione cristiana e sul paradigma relazionale; sul piano pratico si avvale di un percorso sperimentale di attività educativo-formative avviato nel 2011 nel Comune di Montecorvino Pugliano (Salerno).L’ipotesi del progetto verte sulla rivalutazione del concetto di comunità all’interno della realtà scolastica: il capitale sociale è e deve essere prima di tutto capitale umano, affinchè “il noi diventi radice interiorizzata e profonda, capace di far germogliare il bene comune” (Castaldi M. C., 2013).Si delineano gli obiettivi del progetto: “rimettere al centro” l’essere relazionale dell’uomo; riscoprire il significato ontologico della dimensione comunitaria dell’esperienza scolastica; formare l’humus umano fatto di valori e sentimenti comuni.Le metodologie educativo-formative utilizzate si inseriscono nella prospettiva della pedagogia del dono, articolando un circolo virtuoso tra l’educazione del pensiero (John Dewey) e l’educazione del cuore (S. Giovanni Bosco)

Concepts and methods in fault tolerant control with application to a wind turbine simulated system
No full textFaults in automated processes will often cause undesired reactions and shutdown of a controlled plant, and the consequences could be damage to technical parts of the plant, to personnel or the environment. Fault tolerant control combines diagnosis withcontrolmethods to handle faults in an intelligentway. The aim is to prevent that simple faults develop into serious failure and hence increase plant availability and reduce the risk of safety hazards. Fault-tolerant control merges several disciplines into a common framework to achieve these goals. The desired features are obtained through online fault diagnosis, automatic condition assessment and calculation of appropriate remedial actions to avoid certain consequences of a fault. The envelope of the possible remedial actions is very wide. Sometimes, simple re–tuning can suffice. In other cases,accommodation of the fault could be achieved by replacing a measurement from a faulty sensor by an estimate. In yet other situations, complex reconfiguration or online controller redesign is required. This chapter gives an overview of well–established and more recent tools to analyse and explore structure and other fundamental properties of an automated system such that any inherent redundancy in the controlled process can be fully utilised to maintain availability, even though faults may occur. On the other hand, the effectiveness of the analysed solutions has been verified when applied to a wind turbine system. In fact, wind turbine plants are complex dynamic and uncertain processes driven by stochastic inputs and disturbances, as well as different loads represented by gyroscopic, centrifugal, and gravitational forces. Moreover, as their aerodynamic models are nonlinear, both modelling and control become challenging problems. On one hand, high–fidelity simulators should contain different parameters and variables in order to accurately describe the main dynamic system behaviour. Therefore, the development of fault tolerant control solutions for wind turbine systems should consider these complexity aspects. On the other hand, these solutions have to include the main wind turbine dynamic characteristics without becoming too complicated. The second point of this chapter is thus to provide practical examples of the development of robust fault tolerant control strategies when applied to a simulated wind turbine plant. Experiments with the wind turbine simulator represent the instruments for assessing the main aspects of the developed control methodologies

PANFILO CASTALDI (1430? – 1487): IL MEDICO-TIPOGRAFO
No full textJoš uvijek nije razriješena dvojba je li novu metodu tiskanja s pomoću pokretnih metalnih slova zaista izmislio Johann Gutenberg u Mainzu oko 1450. ili je to bio Panfilo Castaldi u
Feltreu (u regiji Veneto), ali je postalo općeprihvaćenim da je riječ o Gutenbergu. Kako bilo, izvan svake je sumnje da je Castaldi, po zanimanju liječnik, među prvima uporabio nov revolucionarni sustav s pomoću kojega je tiskao tekstove velikana medicine poput Hipokrata, Galena i Avicene.
Izdavački mu uspjesi, međutim, nisu pomogli da se obrani od ljute i brojne konkurencije te je na kraju morao napustiti perspektivnu tipografsku djelatnost i vratiti se gotovo potpuno
zanemarenom zvanju liječnika. Ovu njegovu “umjetnost” sugrađani uopće nisu cijenili. Štoviše, tek što je umro, provalili su u tiskaru i, vjerujući da su strojevi “vražji instrumenti”,
potpuno ju razorili.The issue about whether it was Johann Gutenberg in Mainz or Panfilo Castaldi in Feltre (in the Italian region of Veneto) to first invent movable metal type for printing around 1450 still
raises a controversy, even though Gutenberg is generally perceived as the one. What is beyond doubt, however, is that Castaldi pioneered the new revolutionary printing method with
the historical texts written by great physicians such as Hippocrates, Galen, and Avicenna. His early publishing success raised bitter competition all around him, which eventually drove him out of this flourishing business, and he returned to his long-neglected medical profession.
Castaldi’s new “art” was received coldly by his apprehensive fellow citizens. As soon as he was buried, they invaded the printing office and, believing that the printing machines were
the “devil’s instruments”, tore it apart.E’ tuttora irrisolta la questione se verso il 1450 sia stato realmente Johann Gutenberg a inventare a Mainz (Magonza) il metodo di stampa a caratteri mobili di metallo, o se a Feltre
(nel Veneto) Panfilo Castaldi, anche se generalmente si propende per il primo. Sembra che Castaldi abbia avviato i primi esperimenti alcuni anni prima di Gutenberg E’ comunque
fuori dubbio che Castaldi - medico - sia stato tra i primi a occuparsi del nuovo rivoluzionario sistema di stampa, riproducendo i testi dei grandi medici del passato, come Ippocrate, Galeno e Avicenna. Nonostante i successi editoriali, tuttavia, egli fu aspramente avversato dai concorrenti che nascevano numerosi intorno a lui, tanto da essere indotto ad abbandonare la fiorente attività
di tipografo e a riprendere la professione medica che aveva quasi del tutto abbandonato. La nuova “arte” non fu nemmeno apprezzata dai suoi conterranei, che subito dopo la sua
morte invasero la stamperia, e credendo le macchine “strumenti del diavolo” le distrussero completamente

Active Actuator Fault Tolerant Control of a Wind Turbine Benchmark Model
No full textThis paper describes the design of an active fault-tolerant control scheme that is applied to the actuator of a wind turbine benchmark. The methodology is based on adaptive filters obtained via the nonlinear geometric approach, which allows to obtain interesting decoupling property with respect to uncertainty affecting the wind turbine system. The controller accommodation scheme exploits the on-line estimate of the actuator fault signal generated by the adaptive filters. The nonlinearity of the wind turbine model is described by the mapping to the power conversion ratio from tip-speed ratio and blade pitch angles. This mapping represents the aerodynamic uncertainty, and usually is not known in analytical form, but in general represented by approximated two-dimensional maps (i.e. look-up tables). Therefore, this paper suggests a scheme to estimate this power conversion ratio in an analytical form by means of a two-dimensional polynomial, which is subsequently used for designing the active fault-tolerant control scheme. The wind turbine power generating unit of a grid is considered as a benchmark to show the design procedure, including the aspects of the nonlinear disturbance decoupling method, as well as the viability of the proposed approach. Extensive simulations of the benchmark process are practical tools for assessing experimentally the features of the developed actuator fault-tolerant control scheme, in the presence of modelling and measurement errors. Comparisons with different fault-tolerant schemes serve to highlight the advantages and drawbacks of the proposed methodology
Intelligent Fault Diagnosis Techniques Applied to an Offshore Wind Turbine System
No full textFault diagnosis of wind turbine systems is a challenging process, especially for offshore plants, and the search for solutions motivates the research discussed in this paper. In fact, these systems must have a high degree of reliability and availability to remain functional in specified operating conditions without needing expensive maintenance works. Especially for offshore plants, a clear conflict exists between ensuring a high degree of availability and reducing costly maintenance. Therefore, this paper presents viable fault detection and isolation techniques applied to a wind turbine system. The design of the so-called fault indicator relies on an estimate of the fault using data-driven methods and effective tools for managing partial knowledge of system dynamics, as well as noise and disturbance effects. In particular, the suggested data-driven strategies exploit fuzzy systems and neural networks that are used to determine nonlinear links between measurements and faults. The selected architectures are based on nonlinear autoregressive with exogenous input prototypes, which approximate dynamic relations with arbitrary accuracy. The designed fault diagnosis schemes were verified and validated using a high-fidelity simulator that describes the normal and faulty behavior of a realistic offshore wind turbine plant. Finally, by accounting for the uncertainty and disturbance in the wind turbine simulator, a hardware-in-the-loop test rig was used to assess the proposed methods for robustness and reliability. These aspects are fundamental when the developed fault diagnosis methods are applied to real offshore wind turbines
