No full textMeasurement has always been a tool by which we can observe the world around us. This concept was once again confirmed during the 24th IMEKO Technical Committee 4 (TC4) International Symposium, which showed how topics related to the world of measurement range across many fields of knowledge.
The IMEKO TC4 International Symposium is one of the most important events in the fields concerned with the theoretical and practical aspects of the measurement of electrical quantities and related instrumentation. It involves institutions and academia in a discussion of the state of the art and issues that require a joint approach by engineers, academics and other experts of measurement, instrumentation, testing and metrolog
Potere spirituale e temporale nel governo del Patrimonium Sancti Petri tra XII e XIII secolo. Una proposta di rilettura a partire dal caso di Assisi
No full textHistoriography on the papal government of the Patrimonium of St. Peter in the thirteenth century has traditionally considered papal interventions, aimed at consolidating control of the Apostolic See, as essentially unsuccessful. Yet recent research has revised this position, now considered anachronistic. On the basis of these new acquisitions, this contribution intends to highlight how the popes were able to intervene not only on a political level, but also through initiatives of a spiritual nature, which were the prerogatives of their role as head of the universal Church. To demonstrate the effectiveness of the pontiffs’ modes of action through these two spheres, the case of Assisi was chosen as an observatory. Despite the efforts of Innocent III (1198-1216) and Honorius III (1216-1227), the Umbrian city, traditionally an ally of the empire with strong autonomist tendencies, remained tied to the Hohenstaufen until the dawn of the thirteenth century. Subsequently, however, also thanks to the involvement of the Friars Minor in the papal strategy, which culminated with the canonization of Francis and the construction of the basilica dedicated to him during the pontificate of Gregory IX (1227-1241), the city of Assisi distinguished itself during the clash with Frederick II for its adhesion to the pars Ecclesiae

No full textADC Based Measurements:a Common Basis for the Uncertainty Estimation
No full textIn the last years, many Authors have dealt with the uncertainty evaluation of the measurement performed by using an analog-to-digital converter, proposing different approaches to analyze the uncertainty propagation. However, in these studies, in order to identify the uncertainty sources, different sets of parameters are used, and, often, it is not considered that the various uncertainty sources have different modalities of propagation. Obviously, this implies that the various proposed approaches are not directly comparable. One of the main reasons which has caused this situation is the coexistent of various Standards concerning the characterization of the analog-to-digital converters. Therefore, the manufacturers of converters have got a large arbitrariness in choosing and measuring the parameters which specify the performances of their products. With the aim to overtake these limitations and to suggest a common basis, in this paper, we identify, among the large number of parameters proposed by the various Standards, a minimum set of figures of merit which allows a correct uncertainty evaluation of a generic measurement performed by using an analog-to-digital converter. In order to verify the effectiveness of the proposed approach we applied the method to real measurements and compared the results with the ones obtained by means of experimental tests
Velud fulgor meridianus. La «Vita» di papa Gregorio IX. Edizione, traduzione e commento
No full textThe official biography of Gregory IX (1227-1241), handed down anonymously from the Liber Censuum of the Roman Church and unfinished, is a significant testimony to the history of the thirteenth-century papacy. His confrontation with Emperor Frederick II of Staufen, his relations with the religious movements of his time, his policy towards the Patrimony of St. Peter's and the city of Rome, his artistic patronage and life in the curia are narrated in a lofty and magniloquent Latin. Despite the richness of its contents, this source has often been approached with a certain diffidence, mainly due to the circumstances of composition and the ostentatious factiousness of the anonymous author, an open supporter of the pontiff. The edition, the first Italian translation and the historical commentary are preceded by an introduction that aims to shed light on the problems related to the genesis and purpose of the work within the pontifical historiographical tradition and the contemporary curial production

Accounting for the disconnectedness of the economy in OLG models: a case for taxing capital income
No full textThe paper extends the works by Judd [K.L. Judd, Redistributive Taxation in a Simple Perfect Foresight Model, J. Public Econ.28 (1985), 59–83.] and Chamley [C. Chamley, Optimal taxation of capital income in general equilibrium with infinite lives,Econometrica, 54 (1986), 607–622.], who establish that in the long run the capital income tax should be zero, by considering adiscrete time version of the Blanchard–Buiter–Weil perpetual youth model. We show that an independent source of non-zerotaxation arises whenever the economy is “disconnected” and this feature is properly taken into account by the policymaker. Moreprecisely, if the weight attached to each cohort in the social welfare function equals the corresponding actual share in thepopulation, there is a force pushing towards positive taxation of capital income, which acts as a Pigouvian intervention. Moreover,room for this intertemporal correction shrinks as the relative weight of a cohort tends to zero: thus, the optimal tax rate decreaseswith age and tends to zero for the oldest. We also show that our result depends neither on life-cycle behavior, as pointed out by the previous literature on OLG models, nor on population growth
