The Industrial Applicability of PEA Space Charge Measurements, for Performance Optimization of HVDC Power Cables
2019
Cable manufacturing industries are constantly trying to improve the electrical performance of power cables. During the years, it was found that one of the most relevant degradation factors influencing the cable lifetime is the presence of space charge in the insulation layer. To detect the accumulated charge, the pulsed electro-acoustic (PEA) method is the most used technique. Despite the wide use of the PEA cell, several issues are still present. In particular, the PEA output signal is strongly disturbed by the acoustic waves reflections within the PEA cell. This causes the distortion of the output signal and therefore the misinterpretation of the charge profiles. This, in turn, may result…
Eye protein : the cinema of attractions in Guillermo del Toro's Hellboy films
2014
Attraktioelokuva on Tom Gunningin ja André Gaudreaultin kehittämä fraasi kuvaamaan hämmästyksen estetiikkaa, joka oli vallalla varhaisessa elokuvassa ennen narrativisaatiota. Kyseessä on elokuva, joka pitää katsojan tietoisena katsomisesta ottamalla kontaktia katsojaan ja kiehtomalla tämän uteliaisuutta. Attraktion estetiikka ei Gunningin mukaan koskaan hävinnyt, vaan jäi olennaiseksi osaksi kertovaa elokuvaa. Konsepti on ollut hyvin vaikutusvaltainen. Viime vuosina on virinnyt kysymys voisiko sitä käyttää myös tutkiessa Hollywoodin nykyaikaista spektaakkelielokuvaa; sen sanotaan olevan hengeltään lähempänä attraktioelokuvaa kuin vuosikymmeniin. Spektaakkelin korostunut asema―joka usein lii…

Inferring directionality of coupled dynamical systems using Gaussian process priors: Application on neurovascular systems
2022
Dynamical system theory has recently shown promise for uncovering causality and directionality in complex systems, particularly using the method of convergent cross mapping (CCM). In spite of its success in the literature, the presence of process noise raises concern about CCM's ability to uncover coupling direction. Furthermore, CCM's capacity to detect indirect causal links may be challenged in simulated unidrectionally coupled Rossler-Lorenz systems. To overcome these limitations, we propose a method that places a Gaussian process prior on a cross mapping function (named GP-CCM) to impose constraints on local state space neighborhood comparisons. Bayesian posterior likelihood and…
Ultrastructure of posterior sternal glands of Macrotermes annandalei (Silvestri): new members of the sexual glandular set found in termites (Insecta)
2004
0362-2525 (Print) Comparative Study Journal Article; In female alates of Macrotermes annandalei, two types of abdominal glands are involved in the secretion of sex pheromone. Tergal glands are found at the anterior margin of tergites 6-10 and posterior sternal glands (PSGs) are located at the anterior margin of sternites 6-7. The cytological features of both types of glands are quite similar. The fine structural organization of PSGs is studied more precisely and described for the first time. The glandular cuticle is pitted with narrow apertures corresponding to the openings of numerous subcuticular pouches. Several Class 3 glandular units open in each pouch. One canal cell and one secretory…
Design of a Smart Car Park with PV generation and BESS for Grid-on and Grid-off Operation. The SMARTEP Project
2022
The paper presents the design state of a smart car park shelter for electric vehicle in the campus of the University of Palermo. The car park is supplied by the main grid and by a 40 kW photovoltaic system and is equipped with a Li-ion battery storage system with capacity 42 kWh. The hybrid plant is designed in order to operate both in connection with the main grid and in stand-alone mode, supplying, in this case, all car park's loads and providing one recharge to an electric vehicle. Moreover, the energy storage system and, eventually, the battery of one or more cars with V2G technologies, can be managed for providing ancillary services to the grid. In the paper, the design of the system a…
