Georgii Vallae placentini in Iuvenalis Satyras Commentarii. Edizione critica
Full text linkNel presente volume appare la prima edizione critica integrale del commento di Giorgio Valla (1447-1500) a Giovenale, pubblicato in editio princeps a Venezia l’8 novembre 1486. Il commento costituisce un unicum nella variegata costellazione dell’esegesi umanistica dedicata alle Satire dell’Aquinate, in quanto in esso sono disseminate tracce sia del cosiddetto commentum vetustum a Giovenale (V secolo), sia degli scholia recentiora di età carolingia.
L’edizione critica è corredata da indici dettagliati che consentono di ricostruire esaurientemente la mappatura delle fonti antiche impiegate, per redigere il commento, da Giorgio Valla, possessore di una delle biblioteche private più fornite – soprattutto di testi manoscritti greci – nella seconda metà del Quattrocento
Georgii Vallae placentini in Iuvenalis Satyras Commentarii
Full text linkThe present thesis intends to be the first critical edition of the commentary on the Satires of Juvenal published by Giorgio Valla (1447-1500) in Venice in 1486. The significance of this commentary that holds many meaningful traces of the corpus of scholia vetustiora on Juvenal under the name of an otherwise unknown Probus, has been recognized by scholars in the last century. The thesis is divided in four sections: introduction, note on text, commentary with apparatus, indexes. The introduction exposes an outline on the juvenalian studies and lectures in the second half of XVth century undertaken by scholars such as Angelo Sabino, Domizio Calderini and Giorgio Merula, focusing on the more significant contributions of the Giorgio Valla's commentary in the textual criticism and exegesis of the Satires. The introduction also includes a brief summing-up of the classical sources, latin and greek, openly mentioned or word-for-word quoted in the commentary. The note on text deals with the editing standards used in this thesis and also contains some marks on the relationship between the lemmas of the commentary and the text of Juvenal whose margins were filled by the commentary, according to an usual typographic dress for scholastic texts, attempting to define which kinds of handwritten sources of the Satires Valla was able to handle with. The third section is the outright commentary (extended on more than 300 pages in modern format) with a textual apparatus arranged in footnotes that also includes some references to classical sources used but not outspoken by the humanist. The thesis is concluded by three different kinds of indexes (index of classical sources, index of variants, index of names) thought as an useful help for scholars who in future will need to consult this commentary

Frequency control services by a building cooling system aggregate
No full textThis paper proposes a control strategy for managing an aggregate of commercial buildings equipped with Space Cooling Systems (SCSs), called to provide frequency control services to the main grid. The idea is to use the thermal energy stored into buildings to contribute to frequency regulation, during both normal and emergency operating conditions, always preserving the temperature comfort of end-users. Two specific algorithms are developed for two different classes of SCSs: inverter-driven SCSs, which allow the controller to define the current power demanded from the grid, and multi-state SCSs, which allow the controller to switch on-off one of the cooling units that compose the SCSs. In these two different cases, Model Predictive Control and Mixed-Integer Predictive Control, are respectively used to design a load aggregator algorithm able to coordinate the contribution to frequency regulation of each building, depending on their different thermal conditions. A test network model with a high penetration of renewable energy generation is implemented in a dedicated real-time simulation environment, in order to test the effectiveness of the proposed control techniques
Time‐Varying Input‐Output Inoperability Model
No full textRepresenting interdependent critical infrastructures is mandatory for implementing protection policies and strategies. Among the several interdependency models provided over the years, the input-output inoperability model (IIM) has attracted widespread attention due to its simplicity and compactness. Such a model can emphasize cascading effects induced in a complex scenario by dependencies and interdependencies; however, the model is typically set up based on economic data, and the stationary assumption greatly reduces the applicability of the framework. These aspects are crude approximations due to the intrinsic limits of the methodology. Indeed, in modeling realistic scenarios, the coupling of different infrastructures and sectors is expected to increase with outage duration. In this paper, a different formulation of the IIM is proposed where time-varying interdependency coefficients are considered. Such coefficients are defined to explicitly account for the severity and duration of negative phenomena. Some interesting results are obtained from a complex case study including several infrastructures in Italy, emphasizing the features of the proposed methodology. The proposed framework, based directly on operator experience, captures the behaviors induced by the various backup strategies
Memoryless Approach to the LQ and LQG Problems with Variable Input Delay
No full textThis note studies the LQ and LQG problems for linear time invariant systems with a single time-varying input delay and instantaneous (memoryless) state feedback. We extend the memoryless state feedback solution proposed in [1] in two directions. We prove that in the deterministic case a memoryless state feedback can be in general optimal only up to a certain delay, for which we provide a sufficient, and sometimes strict, bound. Moreover, we show that this memoryless control is optimal also in the case of time-varying delays and that the quadratic cost functional has the same value as in the case without delay. For time varying delays the control law requires that the relationship between time points in which the input is generated and applied is known and invertible even if the delay function needs not to be differentiable or even continuous. Finally, we prove that the cost functional is bounded also in the stochastic case for the same delay interval as in the deterministic case, but with a larger cost than the delay-less LQG solution
Operational constrained nonlinear modeling and identification of active distribution networks
No full textThis paper proposes a methodology for the identification of equivalent models of active distribution networks. Due to the increasing installation of distributed generation plants, distribution networks are acquiring an “active” role in the management of the overall power system. In this context, equivalent modeling is becoming essential for allowing transmission system operators to expand the system observability and improve the interoperability with distribution system operators. The present paper proposes a nonlinear model and an identification procedure able to take into account the prior knowledge of a given active distribution network. The result is an equivalent model, which can be easily adapted for reproducing the dynamical behavior of the network with different configurations. The proposed approach is validated through a simulation study on a Benchmark Medium Voltage Active Network
