Economical Analysis of Financial Supports for Large-Scale Photovoltaic PV plants in Eastern Europeen Union Countries
2010
Today, photovoltaic (PV) attracts considerable interest among renewable energy sources (RES), because of its potential to significantly contribute to the future of clean energies. However, PV development is strongly related to the support policies introduced by national governments. The modification or fading out of such support schemes can strongly influence the development of the PV market in any given country. Although the PV market in European developing countries is still quite small, it has been growing rapidly in recent years. Until 2006, the installation of small off-grid PV plants prevailed in eastern EU countries. Starting from 2008, large-scale on-grid PV plants have been put int…
Correlated Channel Model for terrestrial Free Space Optics and project specifications evaluation of LT code in OOK modulation
2011
Free Space Optics is a wireless line-of-sight communication system able to offer good bandwidth performance as well as straightforward installation and relocation. So that it represents a modern technology that allow to realize large bandwidth communication particularly when it is not possible to employ physical cable or radio technologies. Examples of FSO applications are: wireless backaul, fiber backup, temporary links, metro network extension and last mile access[1]. FSO is based on optical signals propagation in air and that is why it suffers of impairments which depend on atmospheric conditions. In detail, FSO suffers of scattering (i. e. Rayleigh and Mie) losses, absorption and scinti…

MAC–Engine: a new architecture for executing MAC algorithms on commodity WiFi hardware
2011
In this demo, we prove that the flexibility supported by off–the–shelf IEEE 802.11 hardware can be significantly ex- tended if we move the control of the MAC programming interface from the driver to the firmware, i.e. from the host CPU to the card CPU. To this purpose, we introduce the concept of MAC–Engine, that is an executor of Pro- grammable Finite State Machines (PFSM) implemented at the firmware level: we show how the card itself can support different protocol logics thanks to PFSM bytecode repre- sentations that can be dynamically injected inside the card memory at run-time without incurring in down time issues or network disconnect events. We provide different PFSM examples in order…

Ancient Artistic Motifs on Italian Memorials from the Unity to the Aftermath of World War I
2022
In the decades subsequent to the unification of the Kingdom of Italy, achieved in 1861 with the proclamation of Vittorio Emanuele II as the king of the new State, the Italian peninsula became covered with many commemorative monuments. These were devoted, first of all, to honour the men who played a leading role in the heroic deeds of the Risorgimento but also to remember the places where the major historical events occurred. Afterwards as well, the Italian State went on erecting memorials, in order to celebrate other facts and casualties, as it happened on the occasion of the unsuccessful colonial attempts in the African land and then, above all, after the World War I. Many of these commemo…

Un Churel Mandir in Gujarat. Note sulla diffusione delle rappresentazioni della figura della strega in India
2021
The churels are figures of the folk imagery of a vast area of South Asia. They, commonly identified with witches, are spirits of women who died during pregnancy or childbirth, and who return to the world of the living, possessing them. The aim of this study is to provide an interpretative analysis of the representations of the churels and of the ambiguous climate that has been created around these figures in recent decades in India. A reflection on the power of the representations of the churels throughout history up to present-day India could be considered a key to penetrating the dense network of relationships and reinventions, but also of divergences and contradictions, sometimes with tr…
Decisional Procrastination in Academic Settings: The Role of Metacognitions and Learning Strategies
2017
Nowadays, university students suffer from a broad range of problems, such as educational underachievement or the inability to control themselves, that lead to procrastination as a consequence. The present research aimed at analyzing the determinants of decisional procrastination among undergraduate students and at assessing a path model in which self regulated learning strategies mediated the relationship between metacognitive beliefs about procrastination and decisional procrastination. 273 students from Southern Italy filled out a questionnaire composed by: the socio-demographic section, the Metacognitive Beliefs About Procrastination Questionnaire, the procrastination subscale of the Mel…
Cardiovascular Management Self-efficacy: Psychometric Properties of a New Scale and Its Usefulness in a Rehabilitation Context.
2015
Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Background: Self-efficacy beliefs have been shown to affect various effective health-promoting behaviors in patients. Unfortunately, availability of reliable and valid measures of self-efficacy in cardiovascular diseases (CVDs) is still very limited. Purpose: The aims of this study were to present a new scale measuring self-efficacy beliefs in managing CVD and to examine its psychometric properties. Methods: The study involved 172 patients (mean age = 66.4…
