Structure and form. Changes of state in architecture – from modern to contemporary
2016
The relationship between the terms Structure and Form, while expressing a consideration on the tectonic component of composition, registers a cyclical evolution of the archi-tecture of the building. The solidity of the Modern, the liquidity of "post-modern conditions", the evaporation of the contemporary aesthetics of disappearance outline a return to a solid state of the matter outlining the basic assumption of formal research in architecture in the sculptural mass of the building.
Adjusting Software Revenue and Pricing Strategies in the Era of Cloud Computing
2016
Competitive forces shape software revenue and pricing models in cloud computing.Different revenue and pricing models lead to different competitive strategies.Software firms apply mixed revenue models, or a hybrid pricing mechanism.Software renting provides flexibility for software providers against competition.Software architecture may either limit possibilities for different revenue models. Recent research has recognized cloud computing as a new paradigm of servitization in which software products are offered based on service contracts. Thus, instead of selling software licenses, software vendors can rent software as a service to customers. However, it is still unclear how software provide…
Mean Field Linear Quadratic Games with Set Up Costs
2013
This paper studies linear quadratic games with set up costs monotonic on the number of active players, namely, players whose action is non-null. Such games arise naturally in joint replenishment inventory systems. Building upon a preliminary analysis of the properties of the best response strategies and Nash equilibria for the given game, the main contribution is the study of the same game under large population. We also analyze the influence of an additional disturbance in the spirit of the literature on H∞ control. Numerical illustrations are provided. © 2012 Springer Science+Business Media New York.
The SCIA Questionnaire: standards for communities for children and adolescents – a tool for the evaluation of good practices
2019
Purpose The purpose of this paper is to present the Italian validation of the standards for communities for children and adolescents (SCIA) Questionnaire, an evaluation tool of communities quality standards, based on the “Service Standards for Therapeutic Communities for Children and Young People – 2nd edition” of the Community of Communities (2009), that enables an empirical, multidimensional and complex evaluation of the therapeutic community (TC) “system”. It is a self-report that sets out and measures variables that allow to get an overview of organisational models and the possible development areas to improve the effectiveness of the protection of child and adolescents in community tr…
The thermophysical characterization of technical elements in the historic architecture: experiences in Palermo
2014
Per contemperare il miglioramento delle prestazioni energetiche e ambientali dell'architettura storica con l'esigenza della sua conservazione, è necessario analizzare le caratteristiche termofisiche dei materiali e degli elementi tecnici che la connotano. Tuttavia la disponibilità di pochi dati in merito si somma alle disomogeneità tipiche della costruzione storica e alle difficoltà di analisi ad esse connesse. In particolare, per la trasmittanza termica delle murature storiche, la letteratura scientifica evidenzia scostamenti anche notevoli tra i valori desunti da misure in situ e quelli calcolati, in genere superiori ai primi. Il contributo espone gli obiettivi e la metodologia di un prog…
A material for memory
2022
Every piece of architecture always aspires to become a monument, if only for the intentionality of meaning, witness and duration that becomes suggestive and evident through the etymological interpretation of the Latin verbs memini, moneo, maneo: every construction, in fact, it recalls the sense of its necessity and essence; it admonishes by arousing respect with the force of the image and the meaning it conveys; it remains durable and, ideally, eternal. There are, then, the architectures specially built to remember in which the utilitas transcends the usual considerations of functional type and sublimates itself in the manifestation of the memory, while the fi rmitas conserves and maintains…
Il tempo sospeso del processo interrotto: oltre la rimozione, un futuro per l’incompiuto
2020
Gli esiti di processi edilizi interrotti sono ascrivibili a una categoria di ambiente costruito anomala, che offre un banco di prova importante per la progettazione tecnologica dell’architettura. Infatti, il finalismo incentrato sul conseguimento di obiettivi e la visione lineare del tempo entrano in crisi a fronte di costruzioni il cui ciclo di vita non ha mai preso avvio, irriducibilmente estranee al presente e il cui futuro è controverso. Il fenomeno bipolare dell’incompiuto offre il quadro a interpretazioni dei suoi legami con la variabile tempo, intesa come fattore di trasformazione e perno del progetto architettonico. Considerandone la diffusione e l’evoluzione, si può delineare per l…
Notice of Violation of IEEE Publication Principles: Robust Delay-Dependent $H_{\infty}$ Control of Uncertain Time-Delay Systems With Mixed Neutral, D…
2011
The problem of robust mode-dependent delayed state feedback H∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the Lyapunov-Krasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is derived based on a convex optimization method such that the resulting closed-loop system is stochastically stable and satisfies a prescribed level of H∞ performance, simultaneously. Finally, two numer…
Multi-label Classification Using Stacked Hierarchical Dirichlet Processes with Reduced Sampling Complexity
2018
Nonparametric topic models based on hierarchical Dirichlet processes (HDPs) allow for the number of topics to be automatically discovered from the data. The computational complexity of standard Gibbs sampling techniques for model training is linear in the number of topics. Recently, it was reduced to be linear in the number of topics per word using a technique called alias sampling combined with Metropolis Hastings (MH) sampling. We propose a different proposal distribution for the MH step based on the observation that distributions on the upper hierarchy level change slower than the document-specific distributions at the lower level. This reduces the sampling complexity, making it linear i…
A Lightweight Network Discovery Algorithm for Resource-constrained IoT Devices
2019
Although quite simple, existing protocols for the IoT suffer from the inflexibility of centralized infrastructures and require several configuration stages. The implementation of these protocols is often prohibitive on resource-constrained devices. In this work, we propose a distributed lightweight implementation of network discovery for simple IoT devices. Our approach is based on the exchange of symbolic executable code among nodes. Based on this abstraction, we propose an algorithm that makes even IoT resource-constrained nodes able to construct the network topology graph incrementally and without any a priori information about device positioning and presence. The minimal set of executab…
