A Microcalcification Detection System in Mammograms based on ANN Clustering
2018
Breast cancer is one of the leading causes to women mortality in the world. Clustered microcalcifications (MCs) in mammograms can be an important early sign of breast cancer, the detection is important to prevent and treat the disease. In this work, we present a novel method for the detection of MCs in mammograms which consists of regions of Interest (ROIs) segmentation, based on a spatial filter that allows the detection of small and large microcalcifications, clustering and classification of MCs by Artificial Neural Network. The system has been tested on a public dataset of digital images and compared with previous approaches. The results demonstrate that the proposed approach could achie…
Students’ Redesign of Mandatory Assignments in Teacher Education
2017
This article explores specific aspects of literacy practices in teacher education in Norway, building upon data collected within the research project Digital literacy and use of learning resources in teacher education in Norway (DigiGLU). Our main aim is to explore how teachers in different subject courses in teacher education (TE) design mandatory assignments, and how students respond to these designs. After the extensive TE-reform in 2010, in revised plans and documents guiding professional training, mandatory assignments (both form and content) were considered more important for the students’ learning process. In our investigation, the concepts of design for learning and design in learni…
The Multimodality of Digital Longform Journalism
2016
Digital longform journalism has recently attracted increased attention among both academics and professionals. This study contributes to the growing body of research by dissecting the multimodal structure of digital longform journalism, that is, how the emerging genre combines written language, photography, short videos, maps and other graphical elements, and joins them together into a seamless narrative using subtle transitions. The data consist of 12 longform articles published in 2012–2013, which have been annotated for their visual and verbal content, their underlying principle of organization and the transitions that hold between them. The annotation is stored into a digital corpus, wh…
Differences in Immaterial Details: Dimensional Conversion and Its Implications for Protecting Digital Designs Under EU Design Law
2021
AbstractThe paper considers three main questions: the legal status of digital designs from the perspective of EU design law, whether the protection is tied to the reproduction of physical products, and whether the scope of protection covers dimensional conversion such as using a 3D design in 2D form or vice versa. There are two sets of views regarding dimensional conversion: the “abstract” and the “concrete” view. These two different attitudes towards the scope of protection influence the manner in which the protectability of digital designs is assessed. In the “abstract” protection, it would not matter whether a product only exists as a digital image and not as a physical shape. In the “co…
THE ROLE OF GOVERNMENT IN ROMANIA’S PARTICIPATION IN DIGITAL ECONOMY
2012
To participate in the digital economy, for a nation, it is imperative the need to adopt ICT, but not only at companies and individuals levels but also on the entire society. The national ICT adoption is significant especially in sustainable economic development of Romania. The degree to which Romania join the digital economy is influenced by measures and policies adopted by the government. The Government should facilitate, motivate and support the adoption of ICT at all three levels: individual, entrepreneurial and governmental. A nation cannot benefit from participation in digital economy when the government vision on the use of modern technology is not sufficiently developed. If Romania w…
Comunicación digital y líneas de fractura en el paradigma de la agenda setting
2006
En: Doxa Comunicación : revista interdisciplinar de estudios de comunicación y ciencias sociales. ISSN 1696-019X n. IV, 2006, pp 37-58 Propone realizar una prospectiva que arroje alguna luz sobre las modificaciones que puede sufrir la teoría de la Agenda Setting, e incluso, eventualmente, su superación, por efecto del desarrollo de los sistemas de comunicación digital. La hipótesis de la que partimos es la de que, si bien la multiplicación y diversificación de medios de comunicación provocada por las tecnologías digitales no tiene por qué haber supuesto, hasta el momento, una diversificación de similar calado en lo que concierne a los temas de interés informativo sancionados por los medios,…
Conceptualization of Digital Competence
2021
The aim of the present research is to study the essence, structure, implementation, and indicators of the concept of the digital transversal competence of university students for its improvement in the study process. This article includes the relevance of transversal competences and the essence of the concept of digital competence. This concept is then developed, the methodology of digital competence assessment and measurement is adapted, and the content analysis method was used to classify and analyze the expression of digital competence in eight professional areas.
Comparative evaluation of molecular methods for the quantitative measure of torquetenovirus (TTV) viremia, the new surrogate marker of immune compete…
2019
Background Torquetenovirus (TTV) viremia is emerging as a promising tool to assess functional immune competence, to predict posttransplant immune-related complications, and eventually to customize immunosuppression. Methods In this study, 327 blood samples were tested using two real-time PCR (rtPCR) assays both targeted to the untranslated region of the TTV genome. The first assay was an in-house rtPCR developed by our group, the second one was the recently marketed TTV R-GENE assay. Results In the validation study, the TTV R-GENE showed good performances in precision and reproducibility, and sensitivity as low as 12 TTV DNA copies/mL, like previously reported for the in-house rtPCR. The Bl…
Alignment of cone beam computed tomography data using intra-oral fiducial markers.
2009
This article illustrates a new method to align and merge two partially overlapping volumes each of them generated by cone beam computed tomography (CBCT). The aggregate volume covers a larger area of investigation and is determined by localizing one fixed LEGO brick in both of the primal volumes. Based on the LEGO brick an approximate registration of the volumes is determined. Afterwards we improve the transformation by minimizing the difference in overlapping space. In this paper we present a method which automates these two steps and provides an aligned volume.
La mediazione o la difficile arte di mettere d’accordo nella Grecia antica. Cosa dire e come dirlo
2017
Conflict resolution always follows the same pattern, whether on an interpersonal or social level or between cities. This paper aims at illustrating the general patterns and at identifying some means of communication with the parties, both in terms of content and in terms of relationship. Regarding the content of the mediation, the following issues will be adressed: the reasons for the resolution, the appeal to a positive relationship between the parties and the mediator himself, the appeal to ‘collaborative individualism’, and the construction of a deep bond between the parties. Concerning relationships, the following issues will be discussed: the importance of a respectful attitude, the ro…
