Current transformers effects on the measurement of harmonic active power in LV and MV networks
2011
The harmonic active power is used to determine the location of polluting loads, the direction of harmonic power flow and to estimate how consequential a certain current harmonic source is. The highest uncertainties, when measuring harmonic active power, are introduced by the current and voltage transducers. This paper presents experimental results which show the impact of current transformers (CTs) on the accuracy of the harmonic power measurements. An expression for the evaluation of the power error in distorted conditions was developed which can be easily utilized in the case of linear current transducers. It is shown how CTs cannot be considered linear transducers and how the higher the …

Lessons learned on student engagement from the nature of pervasive socio‐digital interests and related network participation of adolescents
2021
The rise of modern socio-digital technologies has fundamentally changed the everyday environments in which young people communicate with each other and cultivate interests. To gain a more sophisticated understanding of this phenomenon, this study provides in-depth, qualitative insights into adolescents’ experiences of their socio-digital developmental ecologies. The 15 interview participants were recruited based on a previously conducted questionnaire. The semi-structured theme interview addressed the socio-digital aspects of the participants’ interest-driven behaviours and related networks with the aid of participant-generated egocentric maps. The data not only qualitatively enrich the pic…
La sostenibilità della coppia mista fra familiare e sociale
2013
La ricerca analizza sia i processi macrosociali, riferiti alla comunità, sia i processi micro, propri della dinamica di coppia. Per i primi abbiamo esaminato la percezione di diversità che può scaturire dalle dinamiche intergruppali e l’identità di luogo (intesa come radicamento nel nuovo contesto di accoglienza); per le dinamiche di coppia si sono prese in esame l’impatto che la presenza dei figli genera sulla dinamica di coppia e gli stili educativi adottati. Coerentemente con il metodo d’indagine della ricerca qualitativa, sono state intervistate 22 coppie miste residenti in Sicilia. Il contenuto emerso è stato analizzato con l’ausilio del software Atlas.ti. Tra gli aspetti più salienti …

An Efficient Implementation of Parallel Parametric HRTF Models for Binaural Sound Synthesis in Mobile Multimedia
2020
The extended use of mobile multimedia devices in applications like gaming, 3D video and audio reproduction, immersive teleconferencing, or virtual and augmented reality, is demanding efficient algorithms and methodologies. All these applications require real-time spatial audio engines with the capability of dealing with intensive signal processing operations while facing a number of constraints related to computational cost, latency and energy consumption. Most mobile multimedia devices include a Graphics Processing Unit (GPU) that is primarily used to accelerate video processing tasks, providing high computational capabilities due to its inherent parallel architecture. This paper describes…
One Dimensional Convolutional Neural Networks for Seizure Onset Detection Using Long-term Scalp and Intracranial EEG
2021
Epileptic seizure detection using scalp electroencephalogram (sEEG) and intracranial electroencephalogram (iEEG) has attracted widespread attention in recent two decades. The accurate and rapid detection of seizures not only reflects the efficiency of the algorithm, but also greatly reduces the burden of manual detection during long-term electroencephalogram (EEG) recording. In this work, a stacked one-dimensional convolutional neural network (1D-CNN) model combined with a random selection and data augmentation (RS-DA) strategy is proposed for seizure onset detection. Firstly, we segmented the long-term EEG signals using 2-sec sliding windows. Then, the 2-sec interictal and ictal segments w…
Design and Realization of a Bidirectional Full Bridge Converter with Improved Modulation Strategies
2020
In this paper a Full-Bridge Converter (FBC) for bidirectional power transfer is presented. The proposed FBC is an isolated DC-DC bidirectional converter, connected to a double voltage source&mdash
Teoría de la Participación. Sugerencias analíticas
2002
Human groups may be analysed as organisations of networks of relationships between their members. This article proposes an exercise in theoretic speculation about participation and democracy based on the analytic tools of a relational-informational theory the bases of which come from evolutionalism and the Information Economy. This analytical framework may clarify the nature of macro-collective citizenship, micro-formal group of the company and the fabric of the emergent and informal communicative relations of society and the market. As a humanist heuristic which revindicates the resource to literary and philosophic sources of knowledge, work offers alternative explainations to the preferen…
An experimental analysis of team production in networks
2010
Experimental and empirical evidence highlights the role of networks on social outcomes. In this paper we test the properties of exogenously fixed networks in team production. Subjects make the same decisions in a team-work environment under four different organizational networks: The line, the circle, the star, and the complete network. In all the networks, links make information available to neighbors. This design allows us to analyze decisions across networks and a variety of subjects’ types in a standard linear team production game. Contribution levels differ significantly across networks and the star is the most efficient incomplete one. Moreover, our results suggest that subjects act a…
