The regulator problem with indefinite quadratic cost for boundary control systems: the finite horizon case
No full textArchitetture al Politecnico di Milano. Università è città
No full textIl volume intende evidenziare il ruolo strategico degli insediamenti universitari per lo sviluppo urbano. I nuovi spazi del Politecnico di Milano rispondono alle esigenze di un ateneo moderno e internazionale, impegnato a formare il sapere critico, plasmare l'identità degli studenti e condividere valori e conoscenze, tenendo conto dei bisogni di Milano, una metropoli che guarda all'Europa e al mondo, centro nevralgico dell'economia italiana. Vengono qui illustrati il progetto e la realizzazione del nuovo campus del Politecnico di Milano, ripercorrendo la costruzione della sede storica nella "Città Studi" e presentando infine le nuove proposte dell'ateneo per il futuro del capoluogo lombardo
Master optimization process based on neural networks ensemble for 24-h solar irradiance forecast
No full textIn the paper two models implemented to forecast the hourly solar irradiance with a day in advance are described. The models, based on Artificial Neural Networks (ANN), are generated by a master optimization process that defines the best number of neurons and selects a suitable ensemble of ANN.
The two models consist of a Statistical (ST) model that uses only local measured data and a Model Output Statistics (MOS) that corrects Numerical Weather Prediction (NWP) data. ST and MOS are tested for the University of Rome “Tor Vergata” site. The models are trained and validated using one year data. Through a cross training procedure, the dependence of the models on the training year is also analyzed.
The performance of ST, NWP and MOS models, together with the benchmark Persistence Model (PM), are compared. The ST model and the NWP model exhibit similar results. Nevertheless different sources of forecast errors between ST and NWP models are identified. The MOS model gives the best performance, improving the forecast of approximately 29% with respect to the PM
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Growth and dissection of a fold and thrust belt: the geological record of the High Agri Valley, Italy
Full text linkWe present a 130 km2 wide geological map for the NE side of the fault-bounded High Agri Valley Southern Italy, that formed in the Quaternary in response to extensional tectonics dissecting the folds and thrusts of the Lucanian Apennine. To prepare the map, at 1:25,000 scale, we integrated information obtained through field surveys and the review of pre-existing geological data. Our work describes a number of significant map-scale structures, which can be related to well-constrained tectonic episodes. The new geological map provides important constraints that can be used to distinguish ancient structures from those that were active during the Quaternary, allowing a more detailed reconstruction of the processes that operate during the development of a post-orogenic trough. We expect that the new map will be used for different types of geological investigations, including studies of inversion tectonics, active tectonics, geosite mapping, 3D modelling of geological structures. © 2020, © 2020 The Author(s).
