The essential oil composition of Centaurea immanuelis-loewii Degen growing wild in Bulgaria and chemotaxonomy of section Acrocentron
2021
In the present study, the chemical composition of the essential oil from aerial parts of the Balkan endemic, Centaurea immanuelis-loewii Degen (sect. Acrocentron, Asteraceae), collected in Bulgaria was evaluated by GC-MS. The main components of the oil were β-caryophyllene (23.2%), germacrene D (13.7%) and caryophyllene oxide (12.4%). Furthermore, a complete literature review on the composition of the essential oils of all the other taxa of Centaurea, belonging to section Acrocentron, studied so far, was performed and the chemotaxonomical variations in the composition of the essential oils is discussed.
Feedback practices in English in Norwegian upper secondary schools
2015
The trends that we see both in official guidelines and school practices demonstrate a shift towards formative assessment strategies with an emphasis on feed-forward comments to the students. How this is carried out in schools varies, and the material in this study shows signs of changing evaluation practices in English instruction. One of the changes is an increased tendency to use process-oriented approaches to feedback, in which the students work through a draft several times before handing in a final product. Much of what is commented on in the feedback focuses on how ideas are organised and how the text is structured. Though process writing is a familiar concept from first language writ…
Carattere Universale. Innovazione senza Stile
2019
Il Bauhaus (1919-1933) ha segnato la storia. Questa scuola fu animata da alcuni degli artisti-progettisti più rilevanti del Novecento, da Gropius a Kandinskij, da Itten a Moholy-Nagy, non riconducibili a un approccio univoco. Eppure, l’idea del Bauhaus, che ha innervato il dibattito e la pratica del progetto in Europa e negli USA (e non solo) per decenni, si è risolta in una sorta di International Style che, nella tipografia, corrisponde al carattere Universal di Herbert Bayer (1925). Il presente articolo mira a evidenziare come il carattere universale, che raffigura per noi oggi lo ‘stile’ della Modernità, fu in principio innovazione allo stato puro: una configurazione volta all’effetto, a…
Real-time detection of twitter social events from the user's perspective
2015
Over the last 40 years, automatic solutions to analyze text documents collection have been one of the most attractive challenges in the field of information retrieval. More recently, the focus has moved towards dynamic, distributed environments, where documents are continuously created by the users of a virtual community, i.e., the social network. In the case of Twitter, such documents, called tweets, are usually related to events which involve many people in different parts of the world. In this work we present a system for real-time Twitter data analysis which allows to follow a generic event from the user's point of view. The topic detection algorithm we propose is an improved version of…
3D skeleton-based human action classification: A survey
2016
In recent years, there has been a proliferation of works on human action classification from depth sequences. These works generally present methods and/or feature representations for the classification of actions from sequences of 3D locations of human body joints and/or other sources of data, such as depth maps and RGB videos.This survey highlights motivations and challenges of this very recent research area by presenting technologies and approaches for 3D skeleton-based action classification. The work focuses on aspects such as data pre-processing, publicly available benchmarks and commonly used accuracy measurements. Furthermore, this survey introduces a categorization of the most recent…
FROM MODELING TO IMPLEMENTING THE PERCEPTION LOOP IN SELF-CONSCIOUS SYSTEMS
2010
Engineering self-conscious robotic systems is a challenging issue because of the intrinsic complexity of such systems; a self-conscious robot has to acquire knowledge, to understand its world and to autonomously interact with its environment. In this paper, the externalist point of view is used for developing a complete process for the design and implementation of a conscious robotic system that is able to interact with a dynamic environment in a human-like fashion without possessing detailed knowledge about the environment and pre-programmed tasks and algorithms. The paper mainly focuses on the configuration part of the whole process that make the robot able to decide and to learn from exp…
A Multimodal Fruition Model for Graphical Contents in Ancient Books
2016
One of the most common and efficient way to preserve ancient books is to digitize them, and make their content someway browsable. However, this process often does not take into account the fruition point of view. Exploiting the currently available technologies allows for new ways of content fruition, to attract more people and help them to better understand the available information. In this paper, we present a solution for an innovative and multimodal exploration of ancient books contents, using both touch and touchless gestures. This allows people for both near and far distance interaction, which results in different interaction models.
An Explorable Immersive Panorama
2012
The immersive panoramas are widely used to provide virtual tours of real scene. Their use covers a wide field of applications: art, industry, space research, topography, forensic investigation and all those systems requiring the exploration of a virtual environment which simulates a real one. Often sophisticated devices are used to perform the panorama acquisition. In this paper, we present an image based immersive panorama requiring low cost devices for the acquisition task and provides an innovative human-computer interaction approach. Many panoramic images of the same location are captured. The visualization system changes the panorama in a transparent way with respect to the user intera…
A framework for real-time Twitter data analysis
2016
A framework for real-time Twitter data analysisWe propose improvements to the Soft Frequent Pattern Mining (SFPM) algorithmThe stream of tweets is organized in dynamic windows whose size depends both on the volume of tweets and timeThe set of keywords used to query Twitter is progressively refined to highlight the user's point of viewComparisons with two state of the art systems Twitter is a popular social network which allows millions of users to share their opinions on what happens all over the world. In this work we present a system for real-time Twitter data analysis in order to follow popular events from the user's perspective. The method we propose extends and improves the Soft Freque…
Saliency Based Image Cropping
2013
Image cropping is a technique that is used to select the most relevant areas of an image, discarding the useless ones. Handmade selection, especially in case of large photo collections, is a time consuming task. Automatic image cropping techniques may help users, suggesting to them which part of the image is the most relevant, according to specific criteria. We suppose that the most visually salient areas of a photo are also the most relevant ones to the users. In this paper we present an extended version of our previously proposed method, to extract the saliency map of an image, which is based on the analysis of the distribution of the interest points of the image. Three different interest…
