Moduli DSSC integrati nel vetromattone per la costruzione di pannelli traslucidi fotovoltaici multifunzionali
2012
La proposta illustrerà i primi risultati ottenuti nell’ambito di una ricerca, tutt’ora in corso presso il Dipartimento di Architettura dell’Università degli Studi di Palermo, finalizzata ad indagare le problematiche connesse all’integrazione del vetromattone con sistemi di produzione di energia rinnovabile, in particolare, di terza generazione (DSC-Dye Syntetized solar cell - celle fotovoltaiche organiche/ibride). I principali campi di investigazione che si illustreranno saranno connessi alle: tecniche ed i processi di deposizione delle celle sul vetromattone per la costruzione dei moduli, alla scelta del loro migliore posizionamento ed all’analisi delle ricadute, in termini di valutazione …
An Efficient Intrusion Detection System for Selective Forwarding and Clone Attackers in IPv6-based Wireless Sensor Networks under Mobility
2017
Security in mobile wireless sensor networks is a big challenge because it adds more complexity to the network in addition to the problems of mobility and the limited sensor node resources. Even with authentication and encryption mechanisms, an attacker can compromise nodes and get all the keying materials. Therefore, an intrusion detection system is necessary to detect and defend against the insider attackers. Currently, there is no intrusion detection system applied to IPv6-based mobile wireless sensor networks. This paper is mainly interested in detecting the selective forwarding and clone attacks because they are considered among the most dangerous attackers. In this work, the authors de…
Mechanical Tests on Innovative BIPV Façade Components for Energy, Seismic, and Aesthetic Renovation of High-Rise Buildings
2018
The paper shows the results of mechanical tests carried out on prototypes of a new Building Integrated Photovoltaic (BIPV) component developed by the author and SBskin Smart Building Skin s.r.l. This patented innovative component is able to merge structural function, insulation proprieties, and production of clean energy for retrofit actions and/or the construction of translucent faç
DSSC-integrated Glassblocks for the construction of Sustainable Building Envelopes
2014
The paper shows the first results of the optical performance analysis carried out on the DSSC integrated glassblock, an innovative building product developed at the Department of Architecture of the University of Palermo. In the field of a research that is being conducted in order to define innovative solutions for the construction of photovoltaic and energy efficient translucent building envelopes, different hypotheses of integration of DSSC into the glassblock have been foreseen. The integration of glassblock with third generation PV systems allows to define a novel building-PV product that meets the current requirements of the BIPV (Building Integrated Photovoltaics) market. By means of …
A Survey on Proxy Mobile IPv6 Handover
2016
[EN] As wireless technologies have been improving in recent years, a mobility management mechanism is required to provide seamless and ubiquitous mobility for end users who are roaming among points of attachment in wireless networks. Thus, Mobile IPv6 was developed by the Internet Engineering Task Force (IETF) to support the mobility service. However, Mobile IPv6 is unable to fulfill the requirements of real-time applications, such as video streaming service and voice over IP service, due to its high handover (HO) latency. To address this problem, Proxy Mobile IPv6 (PMIPv6) has been introduced by the IETF. In PMIPv6, which is a network-based approach, the serving network controls mobility m…
Finding an egg in a haystack: variation in chemical cue use by egg parasitoids of herbivorous insects
2023
Egg parasitoids of herbivorous insects use an interplay of short- and long-range chemical cues emitted by hosts and host plants to find eggs to parasitize. Volatile compounds that attract egg parasitoids can be identified via behavioral assays and used to manipulate parasitoid behavior in the field for biological control of herbivorous pests. However, how and when a particular cue will be used varies over the life of an individual, as well as at and below species level. Future research should expand taxonomic coverage to explore variation in chemical cue use in more natural, dynamic settings. More nuanced understanding of the variability of egg parasitoid host-finding strategies will aid in…
La violenza intorno. IPV, pratiche di parenting e fattori di resilienza

Dinamiche relazionali nelle coppie omosessuali con IPV: dal conflitto alla violenza.
2014
La violenza perpetrata nelle relazioni intime è parte di un percorso sistematico di dominanza e di controllo, ed è spesso accompagnata da comportamenti di abuso e di potere. Una delle fonti di conflitto all’interno delle relazioni omosessuali ruota intorno ad uno scarso equilibrio tra partner, all'omofobia interiorizzata o ad una condizione a rischio outing . Scopo dell'indagine, dunque, è stato quello di esaminare il fenomeno della violenza nelle relazioni di coppia omosessuali appartenenti a diverse aree geografiche del Paese. Lo studio, che ha coinvolto 502 individui volontari (185 femmine e 317 maschi; Range 21-58 aa; Metà= 37,96) impegnati affettivamente (conviventi e non), analizza si…
Attitudes and motivation in the treatment of IPV : a case study of two intimately violent men
2017
This case study used qualitative content analysis to examine the cases of two intimately violent men. Both participated in a group intervention but experienced dramatically different outcomes. In the case of "Henri", the intervention was especially successful, but in the case of "Mikael" it was unsuccessful. The data of this study consisted of the video tapes of the men’s therapy sessions, and of the interviews of their spouses. The research questions were the following: 1) Were there changes in the men’s attitudes toward a) women, b) masculinity and c) violent behavior?, 2) How high was the men’s motivation for treatment and making changes in themselves? and 3) Did their attitudes and moti…
Gatherer: an environmental monitoring application based on IPv6 using wireless sensor networks
2013
In this paper, we present an environmental monitoring application based on IPv6 using wireless sensor networks. We show the guidelines to connect this network to internet using the 6LowPAN standard with a real prototype in the evolution of the Internet of Things. We assign a unique IPv6 address to the different nodes motes of the network. Gatherer is based on TinyOS using IPv6 and UDP protocols and allows the data gathering of temperature and relative humidity from the different motes, requesting specific data from individual motes when required, increasing the accuracy of the measures. We compare the performance of our IPv6-based proposed application against others and show the benefits of…
