Influence of different dehydration levels on volatile profiles, phenolic contents and skin hardness of alkaline pre-treated grapes cv Muscat of Alexa…
2020
A dehydration experiment was carried out on Vitis vinifera L. cv Muscat of Alexandria (synonym Zibibbo) following the process for the production of renowned special dessert wines produced on Pantelleria island (Sicily, Italy). Harvested berries were pre-treated in a sodium hydroxide dipping solution (45 g/L, dipped for 185 s, 25 °
A Power Law Behavior in the Incentivized Italian Photovoltaic Market
2018
The Italian photovoltaic (PV) marketis analyzed by using the data contained in the database that describes all PV Plants installed in Italy under the incentive program called “2nd Conto Energia”. It is shown that the cumulative probability distribution of the size of the installed PV plants has a broken power tail. An approach to partially quantify the effect of the economic, juridical and technical rules is introduced in order to show how the regulatory body influences the power tail of the cumulative probability curve.
An Innovative Coupling Solution for Power Line Communication in MV Electrical Networks
2019
One of the main problems in the diffusion of power line communication (PLC) in medium voltage (MV) networks is the need of a dedicated PLC coupler to be installed all over the network. To avoid this problem, the authors have studied, prototyped and patented an innovative PLC coupling solution which uses electrical elements embedded in most of the switchgears already installed in MV networks, i.e. the capacitive dividers of the voltage detecting systems (VDS). The new solution prototype is described in this paper, highlighting the advantages in terms of a significant reduction of both direct costs of equipment and infrastructures and indirect costs of installation and service interruption. T…
Power Line Communication in Medium Voltage Systems: Characterization of MV Cables
2008
The aim of this paper is to illustrate the development of a theoretical and experimental study on the characterization of medium voltage (MV) cables in the frequency range 25-200 kHz. Two transmission line configurations, line-ground and line-line, were considered in order to evaluate the main parameters, such as the characteristic impedance and the attenuation constant alpha. A simplified model of the line-ground configuration is proposed which allows one to evaluate the characteristic impedance and the attenuation constant by means of geometrical dimensions. The model was verified by experimental measurements on commonly used MV cables, RG7H1R, with an aluminium core of different sections…
Haptic Perception in Extreme Obesity: qEEG Study Focused on Predictive Coding and Body Schema
2020
Haptic perception (HP) is a perceptual modality requiring manual exploration to elaborate the physical characteristics of external stimuli through multisensory integrative cortical pathways. Cortical areas exploit processes of predictive coding that collect sensorial inputs to build and update internal perceptual models. Modifications to the internal representation of the body have been associated with eating disorders. In the light of this, obese subjects were selected as a valid experimental model to explore predictive coding in haptic perception. To this purpose, we performed electroencephalographic (EEG) continuous recordings during a haptic task in normally weighted versus obese subjec…
Podstawowe zagadnienia problematyki rekurencji treści cyfrowych
2018
Celem pracy jest wykazanie aktualnych problemów prawnych w związku z ewolucją dystrybucji treści cyfrowych oraz próbą wskazania możliwych innych kierunków zmian w podejściu do sposobu zakupu treści cyfrowej wraz z upowszechnieniem się novum w postaci rozproszonego konsensusu. Ten ostatni spowodował rozpowszechnienie się technologii łańcucha bloków, która wedle koncepcji wizjonerów ma w przyszłości pozwolić na rozproszone usługi hostingowe połączone z nowym podejściem do dystrybucji treści cyfrowych bez nośnika – zarówno dla konsumentów, jak i autorów zdigitalizowanych dzieł.
THE ADMINISTRATIVE JUSTICE IN SPAIN: CURRENT SITUATION AND CHALLENGES
2016
Since the Spanish Constitution of 1978 there has been a full and effective administrative justice. The citizens have the possibility to request a judicial review of decisions taken by the public Administrations, while being either the owners of a subjective right or of a legitimate interest. The interim judicial protection is not limited to the suppression of the act or general provision and the Courts are invested with direct powers to enforce their sentences. However, different problematic issues about the inactivity of the public Administrations and the enforcement of sentences are the new challenges to ensure the administrative justice. To this it must be added that there are problems r…
A Feasible Framework for Maintenance Digitalization
2023
The entire industry is changing as a result of new developments in digital technology, and maintenance management is a crucial procedure that may take advantage of the opportunities brought about by industrial digitalization. To support digital innovation in maintenance management, this study intends to meet the cutting-edge necessity of addressing a transformation strategy in industrial contexts. Setting up a customized pathway with adequate methodologies, digitalization tools, and collaboration between the several stakeholders involved in the maintenance environment is the first step in this process. The results of a previous conference contribution, which revealed important digitalizatio…
Interactively Learning the Preferences of a Decision Maker in Multi-objective Optimization Utilizing Belief-rules
2020
Many real life problems can be modelled as multiobjective optimization problems. Such problems often consist of multiple conflicting objectives to be optimized simultaneously. Multiple optimal solutions exist to these problems, and a single solution cannot be said to be the best without preferences given by a domain expert. Preferences can be used to find satisfying solutions: optimal solutions, which best match the expert’s preferences. To model the preferences of the expert, and aid him/her in finding satisfying solutions, a novel method is proposed. The method utilizes machine learning combined with belief-rule based systems to adaptively train a belief rule based system to learn a domai…
