Rethinking the sGLOH Descriptor
2018
sGLOH (shifting GLOH) is a histogram-based keypoint descriptor that can be associated to multiple quantized rotations of the keypoint patch without any recomputation. This property can be exploited to define the best distance between two descriptor vectors, thus avoiding computing the dominant orientation. In addition, sGLOH can reject incongruous correspondences by adding a global constraint on the rotations either as an a priori knowledge or based on the data. This paper thoroughly reconsiders sGLOH and improves it in terms of robustness, speed and descriptor dimension. The revised sGLOH embeds more quantized rotations, thus yielding more correct matches. A novel fast matching scheme is a…
Application of infrared spectroscopy as Process Analytics Technology (PAT) approach in biodiesel production process utilizing Multivariate Curve Reso…
2019
Abstract Process Analytical Technology means at-line collection of analytical information from the process when the reaction is in progress. Obtained information enables process engineers to better control the Critical Process Parameters and direct the reaction to desirable routs. Near-infrared spectroscopy due to its analytical features, as well as the high capability of automation, versatile sampling and spectral acquisition methods is a useful tool in process monitoring when coupled to chemometrics. The Multiple Scatter Correction preprocessing technique and Alternative Least Square method can extract spectral and concentration information of a reaction mixture simultaneously, were emplo…
Use of Ultrasound in Reconditioning by Welding of Tools Used in the Process of Regenerating Rubber
2018
Addressing the problem of reconditioning large parts is of particular importance, due to their value and to the fact that the technologies for their reconditioning are very complex. The tools used to refine regenerated rubber which measure 660 mm in diameter and 2130 mm in length suffer from a rather fast dimensional wear. Within this research, the authors looked for a welding reconditioning procedure that would allow a very good adhesion between the deposited material layer and the base material. In this regard, the MAG (Metal Active Gas) welding process was used, but the ultrasonic activation of the welding process was also considered. Thus, the wire used for welding was activated conside…
ROS/Gazebo Based Simulation of Co-operative UAVs
2019
UAVs can be assigned different tasks such as e.g., rendez-vous and space coverage, which require processing and communication capabilities. This work extends the architecture ROS/Gazebo with the possibility of simulation of co-operative UAVs. We assume UAV with the underlying attitude controller based on the open-source Ardupilot software. The integration of the co-ordination algorithm in Gazebo is implemented with software modules extending Ardupilot with the capability of sending/receiving messages to/from drones, and executing the co-ordination protocol. As far as it concerns the simulation environment, we have extended the world in Gazebo to hold more than one drone and to open a specif…
A Cognitive Model of Trust for Biological and Artificial Humanoid Robots
2018
Abstract This paper presents a model of trust for biological and artificial humanoid robots and agents as antecedent condition of interaction. We discuss the cognitive engines of social perception that accounts for the units on which agents operate and the rules they follow when they bestow trust and assess trustworthiness. We propose that this structural information is the domain of the model. The model represents it in terms of modular cognitive structures connected by a parallel architecture. Finally we give a preliminary formalization of the model in the mathematical framework of the I/O automata for future computational and human-humanoid application.
Social Practices based characters in a Robotic Storytelling System
2020
In this work, we present a robotic storytelling system, where the characters have been modelled as cognitive agents embodied in Pepper and NAO robots. The characters have been designed by exploiting the ACT-R architecture, taking into account knowledge, behaviours, norms, and expectations typical of social practices and desires resulting from their personality. The characters explain their reasoning processes during the narration, through a sort of internal dialogue that generate a high level of credibility experienced over the audience.
Cloning and training collective intelligence with generative adversarial networks
2021
Industry 4.0 and highly automated critical infrastructure can be seen as cyber‐physical‐social systems controlled by the Collective Intelligence. Such systems are essential for the functioning of the society and economy. On one hand, they have flexible infrastructure of heterogeneous systems and assets. On the other hand, they are social systems, which include collaborating humans and artificial decision makers. Such (human plus machine) resources must be pre‐trained to perform their mission with high efficiency. Both human and machine learning approaches must be bridged to enable such training. The importance of these systems requires the anticipation of the potential and previously unknow…
Expertise in folk music alters the brain processing of Western harmony
2012
In various paradigms of modern neurosciences of music, experts of Western classical music have displayed superior brain architecture when compared with individuals without explicit training in music. In this paper, we show that chord violations embedded in musical cadences were neurally processed in a facilitated manner also by musicians trained in Finnish folk music. This result, obtained by using early right anterior negativity (ERAN) as an index of harmony processing, suggests that tonal processing is advanced in folk musicians by their long-term exposure to both Western and non-Western music.
The Relative Importance of Local and Global Structures in Music Perception
2004
Research in experimental psychology has emotion in music is developed by L. B. Meyer.2 shown two paradoxes in music perception. By According to Meyer, listeners are not passive, mere exposure to musical pieces, Western lis- but rather constantly develop perceptual expectteners acquire sensitivity to the regularities ancies about the possible evolution of the underlying tonal music. This implicitly acquired music. Emotions arise from the way the comknowledge allows listeners to perceive subtle poser (or the improvising performer) fulfills relations between musical events and permits or frustrates these expectancies. To some musically untrained listeners to behave as music- extent, music perc…
Proposal of an innovation framework in an international manufacturing company
2017
Nowadays, companies have to innovate to cope with competition. Several types of innovation exist and have been studied for decades by many authors. However, not many types of innovation are really set up in manufacturing companies operating in a B2B market, and even less the innovation led by users. As far as we know, the specific features of innovation in companies operating in a B2B market have not been greatly studied. Thus, managing innovation in these companies becomes a challenge. The aim of our paper is to analyze the types of innovation which are really set up in a manufacturing company. We also propose an innovation framework. An exploratory experimental study in an international m…
