Integrated thermodynamic and electrical modelling of a variable-speed reversible heat pump: analysis of the cooling mode operation

2022

Variable-speed reversible heat pumps are increasingly adopted for space heating and cooling in residential and tertiary sectors. It is recognized that these systems will play a key role in medium- and small-scale 4th generation district heating and cooling networks. Indeed, with the high penetration of intermittent renewable energy sources, such technology could help reduce issues related to the surplus of electricity from renewable energy sources by converting it into heat or cold. To reliably assess the benefits achievable in these emerging applications, it is necessary to develop models which can simulate not only the steady-state operation but also the dynamic response of the system wit…

EFFETTI DINAMICI DELL’INNALZAMENTO DEL CARICO PER ASSE DI ROTABILI FERROVIARI PER TRASPORTO MERCI

2011

Lo sviluppo di un sistema di trasporto ferroviario merci richiede di minimizzare i tempi di percorrenza e massimizzare la capacità di carico dei convogli. Questo obiettivo può essere raggiunto mediante tre diverse strategie, che possono essere adottate separatamente o in modo congiunto. Le strategie consistono sostanzialmente nell’aumento della capacità di carico del singolo carro, nell’aumento della lunghezza del convoglio e nell’aumento della velocità del veicolo. La possibilità di attuare simultaneamente le tre strategie è possibile solo disponendo di infrastrutture dedicate e utilizzando una progettazione specifica della linea e dei veicoli. Il lavoro illustra gli effetti di un innalzam…

A second strain gradient elasticity theory with second velocity gradient inertia – Part I: Constitutive equations and quasi-static behavior

2013

Abstract A multi-cell homogenization procedure with four geometrically different groups of cell elements (respectively for the bulk, the boundary surface, the edge lines and the corner points of a body) is envisioned, which is able not only to extract the effective constitutive properties of a material, but also to assess the “surface effects” produced by the boundary surface on the near bulk material. Applied to an unbounded material in combination with the thermodynamics energy balance principles, this procedure leads to an equivalent continuum constitutively characterized by (ordinary, double and triple) generalized stresses and momenta. Also, applying this procedure to a (finite) body s…

Violenza bestiale. Modelli dell'umano nella poesia greca epica e drammatica

2013

Quanto è “naturale” il nesso tra violenza e umanità? Ovvero, una violenza rappresentata in termini di bestialità comporta una visione dell’umanità nella quale la violenza è relegata ai margini? Muovendo da queste domande il filo rosso che attraversa tutto il volume è il concetto di ‘antropopoiesi’: strumento euristico, concepito e discusso in campo socio-antropologico, appare qui efficace per sottolineare la dimensione di rappresentazione culturale dell’atto violento. Le situazioni narrative dell’Iliade e della tragedia nelle quali la violenza si manifesta con tratti di ferinità sono dispositivi atti a cogliere la costruzione di un modello di umanità che stabilisce comportamenti, fissa limi…

Un progetto di Archeologia Virtuale a Soknopaiou Nesos nella regione del Fayyum: stato dell’arte e prospettive di ricerca

2016

This work illustrates the first results of the Project of Virtual Archaeology which is now developed by a team of topographer from Salento University (Lecce) together with the équipe of Archaeological Mission of Centro di Studi Papirologici at Soknopaiou Nesos (Fayyum, Egypt). Article also focuses on the main aims of this project : a topographical survey and virtual reconstruction of monuments, digital analysis of data, representation of urban and suburban landscape and their evolution, achievement of a special platform for using the data both on-line and off-line. Keywords : Virtual Archaeology, Soknopaiou Nesos, Archaeological Mission.

Computational discovery of novel trypanosomicidal drug-like chemicals by using bond-based non-stochastic and stochastic quadratic maps and linear dis…

2009

Herein we present results of a quantitative structure-activity relationship (QSAR) studies to classify and design, in a rational way, new antitrypanosomal compounds by using non-stochastic and stochastic bond-based quadratic indices. A data set of 440 organic chemicals, 143 with antitrypanosomal activity and 297 having other clinical uses, is used to develop QSAR models based on linear discriminant analysis (LDA). Non-stochastic model correctly classifies more than 93% and 95% of chemicals in both training and external prediction groups, respectively. On the other hand, the stochastic model shows an accuracy of about the 87% for both series. As an experiment of virtual lead generation, the …
