The Virtual Reconstruction of the Aesculapius and Hygeia Statues from the Sanctuary of Isis in Lilybaeum: Methods and Tools for Ancient Sculptures’ E…

2022

Thanks to recent technological developments in 3D surveys, computer graphics and virtual reality, new scenarios have been opened for the documentation and enhancement of ancient sculptures. When not totally preserved, sculptures can be digitally reproduced, modified and visualized to simulate their physical or virtual reconstruction in a non-invasive way for specialists or for dissemination aims. The virtual sculptural reconstruction process starts usually from the 3D survey of real fragments, and then continues by integrating missing parts with 3D modelling techniques by means of source evaluation. Along with primary data sources (reality-based model), secondary data sources (photos, drawi…

Performance evaluation of a high resolution dedicated breast PET scanner

2016

Purpose: Early stage breast cancers may not be visible on a whole-body PET scan. To overcome whole-body PET limitations, several dedicated breast positron emission tomography (DbPET) systems have emerged nowadays aiming to improve spatial resolution. In this work the authors evaluate the performance of a high resolution dedicated breast PET scanner (Mammi-PET, Oncovision). Methods: Global status, uniformity, sensitivity, energy, and spatial resolution were measured. Spheres of different sizes (2.5, 4, 5, and 6 mm diameter) and various 18 fluorodeoxyglucose (18F-FDG) activity concentrations were randomly inserted in a gelatine breast phantom developed at our institution. Several lesion-to-ba…

Forms of Animality: The Dog

2018

Animals are not the object of zoosemiotics as discussed here, neither is their language nor any other system of signs that affects them directly as living creatures that communicate, but the forms of animality, forms through which the concept of animal itself is socially constructed and transformed over time. Now, if there is one place in which such forms are plain to see, it is in those areas that focus on their nutrition. Looking at feeding animals as a semiotic activity, this paper wants to focus on what I call a nutritional pact, an implicit agreement that binds humans and animals, and that is being continuously negotiated by cultures. A relationship that advertising deeply contributes …

Teaching Language Engineering Using MPS

2021

At universities, computer language handling is most often taught with a focus on compiler theory. However, in practical applications, domain-specific languages (DSLs) are much more important. DSLs implement model-driven technology in an understandable way, as models can be expressed easily using DSLs. One interesting domain for DSLs in this context is language handling itself, and many current tools for language handling are model-driven and based on meta-models. This chapter connects compiler theory and meta-modelling within a university course about language handling. The course features the relevant theory and uses MPS as a practical tool. We show how MPS is used in the course and discus…

Sea Surface Temperatures and Paleoenvironmental Variability in the Central Mediterranean During Historical Times Reconstructed Using Planktonic Foram…

2019

The ongoing anthropogenic‐induced warming assessment requires a robust background from regional sea surface temperature (SST) reconstructions. Planktonic foraminifera have yielded valuable insights into late Quaternary SST dynamics, but the techniques to estimate SST from fossil assemblages have only rarely been used in very recent sedimentary records (the last 2,000 years). Here we use two transfer function methods, modern analog technique and artificial neural networks, to reconstruct SST variability in two cores from the Central Mediterranean Sea that span the last five centuries. Both cores show similar and considerable changes in the planktonic foraminifera assemblages. However, the in…

Corporate governance and its implications for sustainability reporting quality in Latin American business groups

2020

Abstract This paper aims to study the factors determining the quality of sustainability reporting in Latin American business groups. Applying a logistic regression model, this study is pioneer in establishing how some distinct corporate variables of business groups influence disclosure quality of Corporate Social Responsibility practices in these groups in emerging economies. The results show that control concentration in the groups negatively affects the quality of sustainability reporting. Variables such as foreign ownership, the age of the business group and board size help business groups to improve the quality of their sustainability and voluntary disclosure practices. These results fo…

New shape from Shading methods

1993

Shape from Shading is perhaps the most difficult topic to deal with in Artificial Vision: several researchers have faced it using different approaches. The most part of these methods are based on the Horn algorithm so they require very heavy regularity assumptions about the perceived objects' shape and are computationally expensive.

The Making of the Ordinary Child in Preschool

2011

The article examines parent-teacher conferences in Finnish and Swedish preschools. Previous research has shown that the conferences are mostly about the evaluation of the child. Based on qualitative data, the article studies how this evaluation is done. It asks how the institutional order regarding children is constructed in parent-teacher conferences and what the ordinary child is like that this order presumes. The theoretical framework is adopted from social constructionist research on childhood and institutions. The analysis applies a discourse analytic framework. The results suggest that being and becoming social is the key expectation for a child in Finnish and Swedish preschools; form…
