AI and Robotics for waste sorting and recycling
Full text linkA key building block for creating a circular economy is the ability to efficiently recover waste. For recycling to be profitable the purity of the separated fractions must be very high. The aim of the project is to implement a robotised waste sorting system to complement the current commercial solutions. The objective is to improve the quality and quantity of material recovered while limiting costs and labour use. This can be achieved thanks to advanced computer vision and robot manipulation techniques. The system will consist of two main components: (i) a vision system based on Deep Learning (DL) that combines several cameras to achieve high accuracy in material recognition; (ii) a manipulator robot that will sort objects based on feedback from the vision system. Grasp planning will exploit Reinforcement Learning (RL) to learn how to handle complex situations such as singling objects from a stack or disordered flow. The goal of innovation is twofold: to develop Artificial Intelligence techniques to be able to use low-cost sensors and to make system training simple and flexible for high reconfigurability to different types of waste
Smart check 3D: An industrial inspection system combining 3D vision with automatic planning of inspection viewpoints
No full textIn this chapter, we describe an industrial inspection system composed by a 3D vision system, mounted on a manipulator robot arm, able to perform quality and completeness inspection on a complex solid part. The novelty of the system is in the deep integration among three software modules: the visual inspection system, the 3D simulation software, and the motion planning engine of the manipulator robot. This enables an automatic off-line programming of the robot path by specifying in the system the desired inspection tasks. The system automatically generates the needed points of view in order to perform 3D reconstruction and automatic visual inspection. Moreover, the motion planning system can reorder the inspection points in order to optimize the inspection cycle time. The core of this system was developed in the European Project "Thermobot," and currently, it is been engineered to be deployed in an industrial production plant
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dynamic and statistical analysis of giant hail environments in northeast Italy
No full textOn July 24, 2023, the new European record for hail size was set in northeast (NE) Italy with a 19-cm wide hailstone recorded during a supercell outbreak. During this event, severe storms were triggered in the Alps, moved eastward, intensified rapidly in the foothills, and generated damaging hailstorms in the plains. A detailed analysis of the available observations and numerical simulations highlights that the atmospheric environment was unusual. A high-Theta(e) tongue over the Adriatic Sea was lifted by a southerly flow above the cold pool generated by the thunderstorm outflow associated with an initial supercell. This raised the most unstable layer to 1-2 km above mean sea level in the area affected by the record-breaking hailstorm. The vertical profile was characterized by moderate potential instability (likely a value of MUCAPE 1200 J center dot kg(-1) fed the storms) and an intense southwesterly flow in the mid-troposphere. Additionally, there was anomalously high water-vapor transport in the layer 2-5 km above mean sea level. Consequently, high instability seems unnecessary for the occurrence of giant hailstorms in the region. This hypothesis is assessed with a statistical analysis performed for the 2018-2023 period in NE Italy using hail reports and observed soundings. The results show that hail size has a much lower correlation with potential instability (R similar to 0.3) compared with kinematic parameters of the mid-troposphere and water-vapor transport (R similar to 0.5-0.6). Furthermore, thermodynamic parameters have better skill in predicting the occurrence of hail or large hail (> 2 cm), while kinematic parameters of the mid-troposphere are better predictors for very large (> 5 cm) and giant (> 8 cm) hail events
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
