Lo studio ricostruttivo della Torre Mozza nel castello Carlo V di Lecce: dall'analisi dei dati materiali alla restituzione in 3D
2022
The multi-year research activity, carried out under the direction of the Chair of Medieval Archaeology of the University of Salento, has allowed the realization of this work of digital survey and virtual reconstruction of the so-called Tower Mozza in the castle of Charles V in Lecce
Castellaccio of Monreale: From the Survey to the Visualisation of Virtual Reconstructions
2023
On Monte Caputo near Monreale stands a castle, presumably built in the twelfth century. The paper presents the first results of a still in progress survey activity, carried out on the entire monument using laser scanning and photogram-metric methods. This activity was carried out as part of a scientific agreement stipu-lated between the University of Palermo, Department of Architecture and the Club Alpino Siciliano, owner of the Castle. The graphic restitution of the survey provided new information and unpublished images of the castle. It was then possible to formu-late hypotheses on the virtual reconstruction of lost configurations. This was achiev-able thanks to the survey analytical read…
Effects of a structured educational intervention in moderate-to-severe elderly asthmatic subjects.
2019
Background: Adherence to inhaled drugs is linked to patients’ satisfaction with their device, and an incorrect use can negatively affect the outcomes of asthma treatment. We speculated that this is particularly true in elderly asthmatic subjects. Aim: We performed a national pre-post interventional multicentre study, enrolling moderate-to-severe asthmatic subjects aged ≥65 years treated with fixed inhaled combination drugs by dry powder inhaler (DPI) or pressurized metered dose inhaler (pMDI). Adherence and critical errors were evaluated by means of validated questionnaires at first visit (V1) and after 3–6 months (V2). At V1, subjects underwent intensive training on the correct use of the…
Analysis of dietary patterns and nutritional adequacy in lactating women : a multicentre European cohort (ATLAS study)
2021
Abstract Eating habits of lactating women can influence the nutrient composition of human milk, which in turn influences nutrient intake of breastfed infants. The aim of the present study was to identify food patterns and nutritional adequacy among lactating women in Europe. Data from a multicentre European longitudinal cohort (ATLAS study) were analysed to identify dietary patterns using cluster analysis. Dietary information from 180 lactating women was obtained using 3-d food diaries over the first 4 months of lactation. Four dietary patterns were identified: ‘vege-oils’, ‘fish-poultry’, ‘confectionery-salads’ and ‘mixed dishes’. Nutrition adequacy was not significantly different between …
Nutrient intakes of children aged 1-2 years as a function of milk consumption, cows' milk or growing-up milk.
2012
AbstractObjectiveTo evaluate the nutritional adequacy of diets in early childhood as a function of milk intake, cows’ milk (CM) or growing-up milk (GUM).DesignFrom a cross-sectional food consumption survey, two groups of children aged 1–2 years were defined: Group CM fed exclusively on CM ≥ 250 ml/d and Group GUM fed on GUM ≥ 250 ml/d. Proportions of children at risk of nutrient excess or insufficiency were estimated relative to the French Recommended Daily Allowances, Estimated Average Requirements or Adequate Intakes.SettingParents participating in the survey were recruited from all regions of France by a polling organization. Distribution was adjusted to that of the French population.Sub…
Plant Productivity Dispersion and the College Premium: Evidence from the United States 1977-1997
2015
For the United States in 1987-2014, I document at business cycle frequencies that the high-skill workers’ employer size wage premium is high (low) in times of low (high) unemployment relative to that of the low-skill workers. Specifically, the differential employer size wage premium between high-skill and low-skill workers has an unconditional correlation of -0.4 with the unemployment rate, and varies by about 6 percent over the business cycle. The skill premium itself does not exhibit a clear business cycle pattern over the sample period.

Parallel and Distributed Resource Allocation With Minimum Traffic Disruption for Network Virtualization
2017
Wireless network virtualization has been advocated as one of the most promising technologies to provide multifarious services and applications for the future Internet by enabling multiple isolated virtual wireless networks to coexist and share the same physical wireless resources. Based on the multiple concurrent virtual wireless networks running on the shared physical substrate, service providers can independently manage and deploy different end-users services. This paper proposes a new formulation for bandwidth allocation and routing problem for multiple virtual wireless networks that operate on top of a single substrate network to minimize the operation cost of the substrate network. We …
Security in Mobile Wireless Sensor Networks – A Survey
2011
Published version of an article in the journal: Journal of Communications. Also available from the publisher at: http://dx.doi.org/10.4304/jcm.6.2.128-142. OA Thanks to recent advances in robotics, sensors and wireless communications, it is feasible to develop a variety of new architectures for Mobile Wireless Sensor Networks (MWSNs) that play an important role in various applications such as battlefield surveillance, harbor monitoring, etc. However, due to the dynamic of mobile network topology in MWSNs, many new security challenges have emerged. In this article, we give a survey on the state of the art technologies in security aspects of MWSNs. We review existing work that provides securi…
A Java-based Wrapper for Wireless Communications
2008
The increasing number of new applications for mobile devices in pervasive environments, do not cope with changes in the wireless communications. Developers of such applications have to deal with problems arising from the available wireless connections in the given environment. A middleware is a solution that allows to overcome some of these problems. It provides to the applications a set of functions that facilitate their development. In this paper we present a Java-based communication wrapper, called SmartTraffic, which allows programmers to seamlessly use TCP or UDP protocols over Bluetooth or any IP-based wireless network. Developers can use SmartTraffic within their Java applications, t…
