Modelling Recurrent Events for Improving Online Change Detection
2016
The task of online change point detection in sensor data streams is often complicated due to presence of noise that can be mistaken for real changes and therefore affecting performance of change detectors. Most of the existing change detection methods assume that changes are independent from each other and occur at random in time. In this paper we study how performance of detectors can be improved in case of recurrent changes. We analytically demonstrate under which conditions and for how long recurrence information is useful for improving the detection accuracy. We propose a simple computationally efficient message passing procedure for calculating a predictive probability distribution of …
Electronic Structure and Optical Properties of the Intrinsically Chiral 16-Electron Superatom Complex [Au20(PP3)4]4+
2014
The recently solved crystal structure of the [Au20(PP3)4]Cl4 cluster (PP3: tris(2-(diphenylphophino)ethyl)phosphine) is examined using density functional theory (DFT). The Au20 core of the cluster is intrinsically chiral by the arrangement of the Au atoms. This is in contrast to the chirality of thiolate-protected gold clusters, in which the protecting Au-thiolate units are arranged in chiral patterns on achiral cores. We interpret the electronic structure of the [Au20(PP3)4]Cl4 cluster in terms of the superatom complex model. The 16-electron cluster cannot be interpreted as a dimer of 8-electron clusters (which are magic). Instead, a superatomic electron configuration of 1S(2) 1P(6) 1D(6) …
Configurational theory in traditional manufacturing industries: a new model of high-performing small and medium-sized enterprises
2020
The goal of this study is to provide a model of high-performing small and medium-sized companies to address the new environmental challenges in traditional manufacturing industries. Adopting a configurational logic and following an inductive approach based on four high-performing firms, this paper provides new empirical evidence on how the steps followed by these firms are adjusted to the high-performance models prescribed by the literature. In doing so, it also offers a dynamic view of the interrelationships between the strategy and the new conditions of the environment. At a practitioner level, the paper illustrates which recipes are more appropriate to prescribe recommendations for a mor…
The Aqua-Planet Experiment (APE): CONTROL SST Simulation
2013
Climate simulations by 16 atmospheric general circulation models (AGCMs) are compared on an aqua-planet, a water-covered Earth with prescribed sea surface temperature varying only in latitude. The idealised configuration is designed to expose differences in the circulation simulated by different models. Basic features of the aqua-planet climate are characterised by comparison with Earth. The models display a wide range of behaviour. The balanced component of the tropospheric mean flow, and mid-latitude eddy covariances subject to budget constraints, vary relatively little among the models. In contrast, differences in damping in the dynamical core strongly influence transient eddy amplitudes…
Rigenerazione dell’area dell’ex fabbrica tessile Gulì a Palermo
2018
L’attività industriale palermitana, pur avendo vissuto un periodo fiorente piuttosto breve, ha lasciato tracce ben riconoscibili e identificabili all’interno del tessuto urbano, con manufatti architettonici di notevole importanza per qualità di progetto e dimensioni. L’ex fabbrica tessile Gulì è un complesso interessante sia dal punto di vista architettonico sia per la sua localizzazione urbanistica, molto prossima a poli di rilevante interesse culturale. Lo studio, condotto presso il Dipartimento di Architettura dell’Ateneo di Palermo, propone un intervento di rigenerazione che coinvolge non solo i manufatti edilizi presenti ma l’intera area e la sua trasformazione in un nuovo centro di qu…
