“Sources of Research” for the Virtual Reconstruction of Ancient Monuments: The Case of Architectural Models

2023

The use of architectural scale models, also known by the French word maquette or the Italian names plastico or modello, is an ancient practice, which prob-ably began when architecture emerged from its purely practical and utilitarian phase to become a formal category of knowledge with specifically sought-after and deliber-ately selected characteristics, linked to the increased dimensions and the enrichment of forms [1]. The model constitutes a representation, generally on a smaller scale and made of different materials but similar in effect, of a work to be created. Models are made of various materials, in accordance with the tastes of Scholars and with need, such as wood, wax, terracotta, …

Architetture per l’accoglienza tra ricerca e didattica

2019

Lo scritto vuole evidenziare il contributo della didattica del progetto di architettura nei suoi contenuti sociali, a partire da un percorso che mi ha visto studente e, successivamente, ricercatore (PhD). Il progetto di architettura, tra didattica e ricerca, deve essere continuamente attraversato e influenzato dai fenomeni dell’attualità che interessano la città contemporanea e che costituiscono il materiale su cui riflettere. Nella mia esperienza di ricerca, fondamentale si è rivelata la confluenza di diversi saperi (antropologia, sociologia, cinema, arte, fotografia, etc), finalizzati alla costruzione di un quadro di riferimento necessario per interpretare la città contemporanea. L’intrec…

Interazioni metropolitane

2020

Difficile presentare la ricerca di Giovanni Battista Cocco e Adriano Dessi escludendo quanto è accaduto negli ultimi mesi in seguito alla pandemia. Se si dovesse procedere nella riflessione senza tenere conto della diffusione del virus SARS-Cov-2 e della infezione Covid-19, ne scaturirebbe un quadro distorto e forse si apprezzerebbe solo in parte il lavoro dei due ricercatori che, osservando una specifica condizione metropolitana, ne palesano le peculiarità e, utilizzando il progetto di architettura come strumento di indagine, le potenzialità. Perché richiamare la pandemia se il volume è stato concluso poco prima che la sciagura si propagasse? Perché le conseguenze del virus hanno messo in …

Unit Interval Time and Magnitude Monitoring Using Beta and Unit Gamma Distributions

2022

Quick detection of an assignable cause is necessary for process accuracy with respect to the specifications. The aim of this study is to monitor the time and magnitude processes based on unit-interval data. To this end, maximum exponentially weighted moving average (Max-EWMA) control chart for simultaneous monitoring time and magnitude of an event is proposed. To be precise, beta and unit gamma distributions are considered to develop the Max-EWMA chart. The chart’s performance is accessed using average run length (ARL), the standard deviation of run length (SDRL), and different quantiles of the run length distribution through extensive Monte Carlo simulations. Besides a comprehensive simula…

Observation of Poincaré-Andronov-Hopf Bifurcation in Cyclotron Maser Emission from a Magnetic Plasma Trap.

2018

We report the first experimental evidence of a controlled transition from the generation of periodic bursts of electromagnetic radiation into the continuous-wave regime of a cyclotron maser formed in magnetically confined nonequilibrium plasma. The kinetic cyclotron instability of the extraordinary wave of weakly inhomogeneous magnetized plasma is driven by the anisotropic electron population resulting from electron cyclotron plasma heating in a MHD-stable minimum-$B$ open magnetic trap.

Effective cloud optical depth and enhancement effects for broken liquid water clouds in Valencia (Spain)

2017

Partly cloudy skies with liquid water clouds have been analysed, founding that it is essential to distinguish data if the Sun is obstructed or not by clouds. Both cases can be separated considering simultaneously the Cloud Modification Factor (CMF) and the clearness index (kt). For partly cloudy skies and the Sun obstructed the effective cloud optical depth (τ) has been obtained by the minimization method for overcast skies. This method was previously developed by the authors but, in this case, taking into account partial cloud cover. This study has been conducted for the years 2011–2015 with the multiple scattering model SBDART and irradiance measurements for the UV Erythemal Radiation (UV…
