Reti di stazioni permanenti GPS per il posizionamento in tempo reale e sistemi di rilevamento a basso costo
No full textLe tecniche di posizionamento RTK di rete sono oggi
impiegate nelle campagne di misura GPS in alternativa alle tradizionali
tecniche RTK, garantendo risultati più affidabili e di maggior precisione
anche a distanze elevate dalle stazioni di riferimento. L’architettura di
rete, l’installazione e la gestione sono state studiate da due anni per
mezzo di una rete test presso il DITAG (Dipartimento di Ingegneria del
Territorio dell’Ambiente e delle Geotecnologie, Politecnico di Torino).
Modellare all’interno di una rete gli effetti sistematici sul segnale GPS
consente l’invio di correzioni differenziali all’utente finale, supportan-
do applicazioni sia di tipo geodetico che di basso costo. Sono presen-
tati gli algoritmi di stima e modellazione delle correzioni, i formati di
trasmissione, con i risultati della campagna tes
Civiltà della vertigine. A partire da Roger Caillois
No full textIn occasione della pubblicazione integrale della traduzione italiana di "La vertigine della guerra" di Roger Caillois (casa di marrani, 2014, ed.or.: Bellone ou le pente de la guerre), la rivista Kasparhauser propone un'indagine attorno al concetto di vertigine, declinata da Caillois nei diversi ambiti dell'immaginario e del simbolico. Il numero monografico presenta i seguenti contributi: Introduzione; Roger Caillois, Cortesie per la vertigine; Clara Mogno, La logica della guerra e l‟enigma dello Stato. Alcune note sulla guerra in Pierre Clastres; Marco Tabacchini, Estasi addomesticate. La vertigine nell‟epoca della sua produzione tecnicizzata; Roger Caillois, Suggestioni della guerra; Marco Baldino, Darsi alla macchia: nuovo potere, nuova sovranità; Davide Caliaro, La vertigine, l‟erotismo. Brevi appunti sull‟impersonale; Roger Caillois, Conseguenze del nichilismo; Jacopo Valli, Una prassi della vertigine; Giuseppe Crivella, Per una sintassi della vertigine. La pieuvre di Caillois
MABS validation through repeated execution and data mining analysis
No full textAgent Based Modelling is the most interesting and advanced approach for simulating a complex system: in a social context, the single parts and the whole are often very hard to describe in detail. Besides, there are agent based formalisms which allow to study the emergency of social behaviour with the creation and study of models, known as artificial societies. Thanks to the ever increasing computational power, it's been possible to use such models to create software, based on intelligent agents, which aggregate behaviour is complex and difficult to predict, and can be used in open and distributed systems. Data mining is born in the last decades in order to help users in finding useful knowledge from the otherwise overwhelming amount of data available nowadays from the web and the data collected every day by companies. Data Mining techniques can therefore be the keystone to reveal non-trivial knowledge expressed by the initial assumption used to build the micro-level of the model and the structure of the society of agents that emerged from the simulation
On the 700th anniversary of Dante’s death a little geomatics for the Divine Comedy
No full textAs we approach the 700th anniversary of the death of Dante Alighieri, this work seeks to examine his Comedy in its entirety, providing, in the frst instance, a statistical analysis of the places mentioned therein, and another dealing with the characters associated with these places. The analysis is intended to be exhaustive and includes those places, obviously less frequent, outside of Italy (in this regard, it should be remembered that Dante could not have had much greater knowledge of geography than that already condensed in Ptolemy’s Ecumene). To this end, groups of high school students were asked to read all the cantos of the three Canticles of which Dante’s Divine Comedy (by Dante Alighieri) is composed, and to prepare a list of the required data in a properly ordered list. Their dedication and painstaking eforts have provided an indispensable, unvaluable, and essential support for the creation of the database from which the statistical, graphical, and geomatic analyses that form the core of this paper are derived. Next, the variance analysis (performed using the Pearson correlation coefcient) and the connection analysis (performed with the Bonferroni indices) are presented, observing the absence of a law on the average behaviour of the variables treated and yet a not entirely random permutation (in contrast, the values of the correlation coeffcients display curious tendencies in Inferno and Paradiso, refecting Dante’s political ideas, while being almost non-existent in Purgatorio). Lastly, a network is created to organise the information fow between characters and places on the basis of the tables into which the data collected was placed. This network has a functional model similar to that of a levelling network, or a network of potential diferences or fows, in other disciplines (despite the obvious absence of observations and a stochastic-metrological model for them). The data collected are condensed into a series of anamorphic maps that facilitate their reading. The analysis as a whole does not seek to analyse the Divine Comedy but rather to highlight, from a statistical point of view, the rigour of Dante’s creation, in terms of its accuracy and reliability. On the other hand, from a geomatics point of view, the work does provide a further example of the possibilities ofered by geomatics applications that today are able to fnd uses in areas traditionally far removed from geomatics and applied geomatics, such as those of the human sciences
Cytokine cross-talk between phagocytic cells and lymphocytes: relevance for differentiation/activation of phagocytic cells and regulation of adaptive immunity [see comments]
No full textCytokines represent one of the most important elements in the communication among different cell types. They play an increasingly better understood role in the communication among hematopoietic cells and in particular in the reciprocal regulation of effector cell types of innate or natural resistance (phagocytic cells and Natural Killer (NK) cells) and those of adaptive immunity (T and B lymphocytes). Lymphocytes produce several cytokines with either stimulatory (e.g., colony stimulatory factor) or suppressive (e.g., tumor necrosis factors and interferons) effects on proliferation of early hematopoietic cells. Many of these cytokines, alone or acting in synergistic combinations, also have a differentiation-inducing ability on immature myeloid cells and act as powerful potentiators of the cellular functions of terminally differentiated phagocytic cells. The communication between lymphocytes and phagocytic cells is not unidirectional, as phagocytic cells produce factors that regulate lymphocyte activation
