La conoscenza delle emozioni in età prescolare: un contributo alla validazione italiana dell’Emotion Matching Task (EMT)
2013
Lo studio presenta i dati relativi alla validità di criterio dell’EMT (Izard et al., 2003), una misura della conoscenza delle emozioni in età prescolare. La validità di criterio è esaminata in relazione alla regolazione emotiva dei bambini, alla loro competenza sociale e alla manifestazione di problemi comportamentali di natura internalizzata ed esternalizzata. I dati sono preliminarmente analizzati in funzione dell’età e delle abilità verbali. Hanno partecipato allo studio 120 bambini, divisi in tre gruppi: 3, 4 e 5 anni. Oltre all’EMT, sono stati somministrati il PPVT (Dunn e Dunn, 1997; Stella, Pizzoli e Tressoldi, 2000), l’ERC (Molina et al., 2014; Shields e Cicchetti, 1997) e l’SCBE (L…
A Simple Multibody Dynamic Model of Cross-Country Ski-Skating
2013
The purpose of this paper is to present the development of a simple multibody dynamic model matching the observed movements of the center of mass of a skier performing the skating technique in cross-country skiing. The formulation of the equation of motion was made using the Euler–Lagrange equations applied to a multibody tree-type system in three dimensions. The description of the lower limb of the skier and the ski was completed by employing three bodies, one representing the ski, and two representing the natural movements of the leg of the skier. This simple model is able to show an approximation of the movement of the center of mass of the skier and its velocity behavior allowing to stu…
Electromagnetic optimization of passive RFID sensor nodes
2012
RFID passive tags are nowadays starting to be considered more than labeling devices: by properly analyzing the two-ways communication link it is possible to get information about the state of a tagged object, without any specific embedded sensor or local power supply. Despite of the generality and the straightforwardness of the approach, the design of such a class of devices requires specific strategies to make the radio-sensors able to properly track the evolution of the phenomena under observation, jointly optimizing communication and sensing requirements. In this paper the optimization problem is formalized by means of convenient matching charts and evaluated in realistic experimental ex…
Including the environmental criteria when selecting a wastewater treatment plant
2014
Abstract Life Cycle Assessment (LCA) is a methodology to generate environmental impact estimates associated with the life cycle stages of a product or process. The approach facilitates a more comprehensive outlook of the end-of-pipe process impacts, in which wastewater treatment plants (WWTPs) are included. Here we describe the implementation of the LCA methodology within a knowledge-based Decision support system (DSS) in order to include the environmental criteria to the decision making process when selecting the most appropriate process flow diagrams for specific scenarios. A sample group of 22 actual operating facilities in Spain, corresponding to five different typologies were assessed …
Economic evaluation of PV system for EV charging stations: Comparison between matching maximum orientation and storage system employment
2016
This article addresses the problem of the choice of a generation system to be implemented to reduce the impact of charging electric vehicles at University. Based on the behaviour of the student population, it is identified the electrical load. Two possible solutions are evaluated in order to manage the peak load: an orientation of the panels in order to increase the power at defined time and the use of storage system. The main strength and weakness points of two systems are investigated by taking into account the Levelized Cost of Energy.
Reconfigurable dualband antenna module with integrated high voltage charge pump and digital analog converter
2014
Integration of a reconfigurable antenna module for handheld applications employing a set of novel technologies is demonstrated. A low profile dualband hybrid dielectric resonator antenna (DRA) based on glass-ceramics and a tunable matching network (TMN) based on ferroelectric varactors with a maximum biasing of 90V form a reconfigurable antenna module. The control of the antenna module is performed by a 120V CMOS high voltage (HV) charge pump with an 8-bit digital analog (D/A) converter generated from a 3.7V battery. Adaptive impedance matching at the lower band of 1.9 GHz is carried out by the TMN when the dualband antenna is exposed to different operation scenarios. Meanwhile, the upper b…
A robust fault detection design for uncertain Takagi-Sugeno models with unknown inputs and time-varying delays
2013
Abstract This paper investigates the problem of robust fault detection system design for a class of uncertain Takagi–Sugeno (T–S) models. The system under consideration is subject to unknown input and time-varying delay. The fault detection system is designed such that the unknown input is thoroughly decoupled from residual signals generated by the fault detection system. Furthermore, the residual signals show the maximum possible sensitivity to the faults and the minimum possible sensitivity to the external disturbances. The model matching approach is utilized to tackle the effects of parametric uncertainties in the model of the system. The design procedure is presented in terms of Linear …
Foreign capital, credit constraints and continuity of firms’ R&D
2015
ABSTRACTIn this article, we investigate the role of foreign capital participation as a means for firms to overcome the obstacle posed by credit constraints to sustain R&D investments. Using data for Spanish manufacturing firms in the period 1990–2006, we show that firms with foreign capital are significantly less likely to stop already initiated R&D projects and also more likely to sustain R&D investment when facing credit constraints. Our results are robust to positive selection into foreign capital participation, which we control through a set of variables chosen from a propensity score estimation, and to firms’ fixed-effects.
Foreign Taleovers and Wages: Theory and Evidence from Hungary
2005
This study discriminates FDI technology spillover from learning effects. Whenever learning takes time, our model predicts that foreign investors deduct the economic value of learning from wages of inexperienced workers and add it to experienced ones to prevent them from moving to local competitors. Hence, the national wage bill is unaffected by foreign takeovers. In contrast to learning, technology spillover effects occur whenever a worker with MNE experience contributes more to local firms’ than to MNEs’ productivity. In this case, experienced MNE workers are hired by local firms and the host country obtains a welfare gain. We investigate empirically wages, productivity, and worker turnove…
RootsGLOH2: embedding RootSIFT 'square rooting' in sGLOH2
2020
This study introduces an extension of the shifting gradient local orientation histogram doubled (sGLOH2) local image descriptor inspired by RootSIFT ‘square rooting’ as a way to indirectly alter the matching distance used to compare the descriptor vectors. The extended descriptor, named RootsGLOH2, achieved the best results in terms of matching accuracy and robustness among the latest state-of-the-art non-deep descriptors in recent evaluation contests dealing with both planar and non-planar scenes. RootsGLOH2 also achieves a matching accuracy very close to that obtained by the best deep descriptors to date. Beside confirming that ‘square rooting’ has beneficial effects on sGLOH2 as it happe…
