An Architecture for Telenoid Robot as Empathic Conversational Android Companion for Elderly People
2015
In Human-Humanoid Interaction (HHI), empathy is the crucial key in order to overcome the current limitations of social robots. In facts, a principal defining characteristic of human social behaviour is empathy. The present paper presents a robotic architecture for an android robot as a basis for natural empathic human-android interaction. We start from the hypothesis that the robots, in order to become personal companions need to know how to empathic interact with human beings. To validate our research, we have used the proposed system with the minimalistic humanoid robot Telenoid. We have conducted human-robot interactions test with elderly people with no prior interaction experience with …
Restoration and Enhancement of Historical Stereo Photos Through Optical Flow
2021
Restoration of digital visual media acquired from repositories of historical photographic and cinematographic material is of key importance for the preservation, study and transmission of the legacy of past cultures to the coming generations. In this paper, a fully automatic approach to the digital restoration of historical stereo photographs is proposed. The approach exploits the content redundancy in stereo pairs for detecting and fixing scratches, dust, dirt spots and many other defects in the original images, as well as improving contrast and illumination. This is done by estimating the optical flow between the images, and using it to register one view onto the other both geometrically …
Challenges for the Teacher's Role in Promoting Productive Knowledge Construction in Computer-Supported Collaborative Learning Contexts
2010
This chapter discusses challenges related to teachers’ pedagogical activities in facilitating productive discussions among students in Computer-Supported Collaborative Learning (CSCL) contexts. In the light of two different cases from secondary-level and higher education contexts, the authors examine how teachers’ pedagogical choices influenced the quality of students’ activity, namely Web-based discussion. The results of our studies indicated that rich moments of collaboration were rare and distributed unequally among the students. The obvious weakness from the perspective of teachers’ pedagogical activities was that in neither of the studies was the students’ interaction in the discussion…
Modelling thermionic emission by using a two Level mechanical system
2008
The Boltzmann factor is at the basis of a great amount of thermodynamic and statistical physics, both classical and quantum. It describes the behaviour of natural systems that exchange energy with the environment. However, why does the expression have that specific form? The Feynman Lectures on Physics justifies it heuristically by referencing to the "exponential atmosphere" example. Thermodynamics textbooks usually give a more or less complete explanation that mainly involves a mathematical analysis, where it is hard to see the logic flow. Moreover, the necessary mathematics is not at the level of high school or college students' preparation. Here we present an experiment and a simulation …

Cloud screening and multitemporal unmixing of MERIS FR data
2007
The operational use of MERIS images can be hampered by the presence of clouds. This work presents a cloud screening algorithm that takes advantage of the high spectral and radiometric resolutions of MERIS and the specific location of some of its bands to increase the cloud detection accuracy. Moreover, the proposed algorithm provides a per-pixel probabilistic map of cloud abundance rather than a binary cloud presence flag. In order to test the proposed algorithm we propose a cloud screening validation method based on temporal series. In addition, we evaluate the impact of the cloud screening in a multitemporal unmixing application, where a temporal series of MERIS FR images acquired over Th…
Las cooperativas de crédito como entidades colaboradoras de la Administración tributaria
2000
Nowadays the collaboration of private citizens in tax collection management is essential for effective tax collection. For credit cooperatives, collaborating with the State Agency for Tax Administration in tax collection management means public recognition of their ability as financial operators and their economic standing and financial management capability, as well as the possibility of providing more services for their members.
Evaluation of Occupational Training Programs for women
2006
This paper summarizes the results obtained from the evaluation of Occupational Training Programs through which we checked the quality of service and the efficiency of the introduction of women into the labour market, as well as the need to promote quality Occupational Training specifically for women that will not only facilitate their introduction into the labour market by adapting their personal skills to its needs, but will also encourage personal and social improvement.
“The Same Staff Can Be Enough”. Employers’ Resilience Strategies in Recruitment Decisions
2018
Studies on resilience have sprung from a need to understand the survival strategies of organizations when faced with the emergence of unexpected, potentially destructive and negative events in the lives of the organizations. This article, on the other hand, intends to highlight organizational resilience when confronted with unexpected positive events, seldom considered by such studies. This is the well-known macroeconomic phenomenon of the time lag between economic growth and labor demand at the moment that a regressive economic cycle is reversed. With which strategies do companies, in the face of such an event, transform a resilient attitude into real resilient behavior? Five strategies of…
Anchoring symbols to conceptual spaces: the case of dynamic scenarios.
2003
In recent years, there have been several proposals for the realization of models inspired to biological solutions for pattern recognition. In this work we propose a new approach, based on a hierarchical modular structure, to realize a system capable to learn by examples and recognize objects in digital images. The adopted techniques are based on multiresolution image analysis and neural networks. Performance on two different data sets and experimental timings on a single instruction multiple data (SIMD) machine are also reported.
