Francesco Bongioannini: ispiratore del primo provvedimento > (decreto e circolare ministeriale del 21 luglio 1882)
2008
Francesco Bongioannini (1847-1928)fu un ingegnere con ruolo ispettivo che ha operò per un lungo periodo in seno alla Direzione generale di AABB. Nell’ambito del restauro architettonico, fu l’estensore di norme e direttive per una generale e centralizzata opera di controllo sull’azione conservativa dei monumenti. L’iniziativa di maggiore rilievo riguardò la stesura del Decreto Ministeriale del 21 luglio 1882 «Sui restauri degli edifizi monumentali» e della relativa circolare applicativa n. 683 bis. Il decreto e la circolare costituirono le più aggiornate acquisizioni prodotte dal dibattito sulla nascente disciplina del restauro architettonico e rappresentarono un fondamentale punto di riferi…
On Pareto optima, the Fermat-Weber problem, and polyhedral gauges
1990
This paper deals with multiobjective programming in which the objective functions are nonsymmetric distances (derived from different gauges) to the points of a fixed finite subset of ℝn. It emphasizes the case in which the gauges are polyhedral. In this framework the following result is known: if the gauges are polyhedral, then each Pareto optimum is the solution to a Fermat—Weber problem with strictly positive coefficients. We give a new proof of this result, and we show that it is useful in finding the whole set of efficient points of a location problem with polyhedral gauges. Also, we characterize polyhedral gauges in terms of a property of their subdifferential.
Her Mistress's Voice: Gynophonocentrism in Feminist Discourses
2000
I will trace the metaphors of voice in the discourses of feminisms as articulated by Judith Fetterley, Kaja Silverman, Julia Kristeva, and Hélène Cixous. I will analyze the presuppositions of their vocal or sound imagery, paying special attention to the implications of the essentialism/constructivism opposition. It is not my intention to provide a comprehensive account of voice in feminisms, nor to make sweeping generalizations on the basis of a very limited corpus. Moreover, in spite of their differences in cultural background, period, and main area of study, the four theorists to be read are, as it were, within earshot from each other, centering, whether anglo- or francophone, around the …

A Feature Rich Distance-Based Many-Objective Visualisable Test Problem Generator
2019
In optimiser analysis and design it is informative to visualise how a search point/population moves through the design space over time. Visualisable distance-based many-objective optimisation problems have been developed whose design space is in two-dimensions with arbitrarily many objective dimensions. Previous work has shown how disconnected Pareto sets may be formed, how problems can be projected to and from arbitrarily many design dimensions, and how dominance resistant regions of design space may be defined. Most recently, a test suite has been proposed using distances to lines rather than points. However, active use of visualisable problems has been limited. This may be because the ty…
Stability in a System subject to Noise with Regulated Periodicity
2011
The stability of a simple dynamical system subject to multiplicative one-side pulse noise with hidden periodicity is investigated both analytically and numerically. The stability analysis is based on the exact result for the characteristic functional of the renewal pulse process. The influence of the memory effects on the stability condition is analyzed for two cases: (i) the dead-time-distorted poissonian process, and (ii) the renewal process with Pareto distribution. We show that, for fixed noise intensity, the system can be stable when the noise is characterized by high periodicity and unstable at low periodicity.
