Linee di indirizzo per il miglioramento dell’efficienza energetica nel patrimonio edilizio
2016
Questo scritto fa esplicito riferimento alle “Linee d’indirizzo per il miglioramento dell’efficienza energetica nel patrimonio culturale - Architettura, centri e nuclei storici ed urbani”, recentemente redatte da un gruppo di lavoro composto da dirigenti e funzionari del Ministero dei Beni e delle Attività Culturali e del Turismo (MiBACT) e da docenti universitari, per fornire indicazioni per la valutazione e per il miglioramento della prestazione energetica del patrimonio culturale tutelato, con riferimento alle norme italiane in materia di risparmio e di efficienza energetica degli edifici. Tali linee di indirizzo costituiscono uno strumento scientifico semplice, ma in grado di coniugare …
Robustifying principal component analysis with spatial sign vectors
2012
In this paper, we apply orthogonally equivariant spatial sign covariance matrices as well as their affine equivariant counterparts in principal component analysis. The influence functions and asymptotic covariance matrices of eigenvectors based on robust covariance estimators are derived in order to compare the robustness and efficiency properties. We show in particular that the estimators that use pairwise differences of the observed data have very good efficiency properties, providing practical robust alternatives to classical sample covariance matrix based methods. peerReviewed
Rule of the One: Avicenna, Bahmanyār, and al-Rāzī on the Argument from the Mubāḥathāt
2020
Avicenna is a strong proponent of what some of the later ones call qāʻidat al-wāḥid or ‘rule of the one’ (RO). The gist of RO states: from the one only one directly proceeds. In the secondary literature, discussion of this Avicennian rule is usually limited to a particular application of it i.e., the issue of emanation. As result, it’s not really clear what RO means, nor why Avicenna endorsed it. In this paper, I try and remedy this situation by doing two things – one on the taṣawwur front, the other on the tasdīq. First, explain just what the terms of RO amount to – that is, its subject and predicate. In doing this, I distinguish between a narrow and a broad understanding of RO, and the sh…
Psychrophiles: A source of cold-adapted enzymes for energy efficient biotechnological industrial processes
2021
Biocatalysts are the backbone of bioprocessing industries that are going through a phase of transition with reference to the requirement of extraordinary enzymes for various biochemical processes. This transition is well reported and documented by various researchers through elucidation of different features and applications of mesophilic and thermophilic enzymes. However, there is little information available about psychrophilic enzymes and their involvement in industrial processes. Therefore, understanding the features and functions of psychrophilic enzymes could suggest some of their novel applications in various industries such as food, agriculture, chemicals, pharmaceuticals, and waste…

THE EVOLUTION OF THE SEWAGE TREATMENT PROCESS IN ROMANIA IN THE LAST 30 YEARS: CASE STUDY RÂMNICU VÂLCEA
2012
The evolution of the sewage treatment process in Romania in the last 30 years: case study Râmnicu Vâlcea. Most studies made at national level in the domain of hydrology target the surface water topic, analyzing the hydrometric and hydrologic characteristics and the quality of the water for certain catchment areas. This paper aims instead the relatively new field of urban hydrology, more exactly the urban wastewater treatment process. The study is based on the observations made in the first half of the year 2010 at the wastewater treatment plant from Râmnicu Vâlcea and on the analysis of some relevant wastewater quality indicators before and after the treatment process for the period between…
Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application
2021
This paper presents a detailed analysis of the use of a novel Harmonic Mitigation algorithm for Cascaded H-Bridge Multilevel Inverter in electrical drives for the transportation field. For this purpose, an enhanced mathematical model of Interior Permanent Magnet Synchronous Motor (IPMSM), that takes into account simultaneously saturation, cross-coupling, spatial harmonics, and iron loss effects, has been used. In detail, this model allows estimating accurately the efficiency and the torque ripple of the IPMSM, crucial parameters for transportation applications. Moreover, two traditional pulse width modulation strategies, Sinusoidal Phase-Shifted and Switching Frequency Optimal Phase-Shifted…

Single Event Burnout of SiC Junction Barrier Schottky Diode High-Voltage Power Devices
2018
Ion-induced degradation and catastrophic failures in high-voltage SiC Junction Barrier Schottky (JBS) power diodes are investigated. Experimental results agree with earlier data showing discrete jumps in leakage current for individual ions, and show that the boundary between leakage current degradation and a single-event-burnout-like effect is a strong function of LET and reverse bias. TCAD simulations show high localized electric fields under the Schottky junction, and high temperatures generated directly under the Schottky contact, consistent with the hypothesis that the ion energy causes eutectic-like intermixture at the metal- semiconductor interface or localized melting of the silicon …
