L'allevamento bovino nella Vale del Torto: un caso di zootecnia sostenibile in Sicilia
2011
La zootecnia pur non risultando tra le principali attività del settore agricolo siciliano, riveste un ruolo di estrema importanza sociale, ancor più che economica, per ampie zone della Sicilia. La crisi che dagli inizi degli anni 2000 investe il settore, ed in particolare quello bovino, ha provocato tanto la chiusura di un elevato numero di allevamenti che una forte contrazione dei capi allevati, siano essi ad indirizzo carne che ad indirizzo latte. La zootecnia bovina ad indirizzo carne presente nella Valle del Torto, in provincia di Palermo e zona oggetto del presente studio, ha per molti decenni decisamente contribuito allo sviluppo di una comunità rurale che su questa attività ha creato…
Taking Advantage of Selective Change Driven Processing for 3D Scanning
2013
This article deals with the application of the principles of SCD (Selective Change Driven) vision to 3D laser scanning. Two experimental sets have been implemented: one with a classical CMOS (Complementary Metal-Oxide Semiconductor) sensor, and the other one with a recently developed CMOS SCD sensor for comparative purposes, both using the technique known as Active Triangulation. An SCD sensor only delivers the pixels that have changed most, ordered by the magnitude of their change since their last readout. The 3D scanning method is based on the systematic search through the entire image to detect pixels that exceed a certain threshold, showing the SCD approach to be ideal for this applicat…
L'ex convento e carcere di San Vito di Agrigento. Studi e proposte per la sua conservazione
2020
Il saggio “L’ex convento carcere di San Vito di Agrigento. Studi sulle trasformazioni e proposte per la sua conservazione” indaga l’antico convento dei frati Minori di Agrigento, trasformato nel sec. XIX in carcere di Agrigento. Il convento, costruito fuori le mura della città, era costituito dalla chiesa, dal chiostro e dal convento con le celle e gli spazi comuni dei frati. La nuova destinazione a carcere, con i lavori effettuati tra la metà del sec. XIX, primi e metà del sec. XX, ha in parte distrutto e occultato il convento medievale. Nell’Anno Accademico 2011-2012, i due corsi di Laboratorio di Restauro e Teoria e Storia del Restauro, del Corso di laurea in Architettura, sede di Agrige…
Myocardial Infarction Quantification from Late Gadolinium Enhancement MRI Using Top-Hat Transforms and Neural Networks
2019
Significance: Late gadolinium enhanced magnetic resonance imaging (LGE-MRI) is the gold standard technique for myocardial viability assessment. Although the technique accurately reflects the damaged tissue, there is no clinical standard for quantifying myocardial infarction (MI), demanding most algorithms to be expert dependent. Objectives and Methods: In this work a new automatic method for MI quantification from LGE-MRI is proposed. Our novel segmentation approach is devised for accurately detecting not only hyper-enhanced lesions, but also microvascular-obstructed areas. Moreover, it includes a myocardial disease detection step which extends the algorithm for working under healthy scans.…
Imaging Evaluation of Facial Complex Strut Fractures
2012
High-resolution multidetector computed tomography with multiplanar reformations and 3-D postprocessing often provides the detail necessary for preoperative assessment of facial injuries. Maxillofacial fractures are classified in the following manner: upper face fractures, midface fractures (the most frequent), Le Fort fractures, and lower face or mandible fractures. The facial skeleton is a framework of vertical and horizontal buttresses that ensures a better resistance to trauma, but serves also as reference for maxillofacial surgery to restore facial size and shape. Radiologists should know how to diagnose and report the main types of facial fracture.
Vehicle localization based on scene perception
2021
The vision-based vehicle localization task is tackled as an image-based place recognition problem in this thesis. As image representation is an important process to place recognition, we proposed place recognition methods focusing on increasing the quality of image features. First, the dynamic object removal step is proposed to remove the dynamic objects, such as vehicles and pedestrians, of an image by semantic segmentation method and restore their background information by image inpainting method. Second, reducing instead of removing the noisy information of an image is proposed. Using the image blurring method to reduce the image noise, the performance of place recognition is improved wi…
The Multi-States (MuSt) Theory for Emotion- and Action-regulation in Sports
2020
Feeling states – including emotional experiences – are fundamental to human adaptation, as they influence effort, attention, decision making, memory, and behavioural responses of individuals, as well as their interpersonal interactions. Thus, the ability to self-regulate is crucial for athletic success. This chapter presents the multi-states (MuSt) theory as a holistic approach for both emotion- and action-centred self-regulation for performance enhancement and optimisation. Central to the MuSt theory is the notion that a combination of emotion- and action-regulation strategies is more effective than focusing on one aspect alone. In this chapter, we describe psychobiosocial feeling states a…
New Approaches to Regulating the Activities of Rating Agencies: A Comparative Analysis
2016
Abstract Rating agencies have become an important part of the global financial landscape. Formation of credit ratings is specified by the inherent asymmetry of financial market information and general interest in the transformation of a large amount of diverse and segmented financial information in a simple and clear assessment of the credit surveillance of borrowers that is credit rating. The world financial crisis started in 2008 has again put on the agenda the question of rating assessment accuracy and the factors influencing the rating migration. The activity of rating agencies, until recently, has had little regulation, allowing rating agencies to avoid responsibility for inaccuracies …
‘Classical’ doping, financial doping and beyond: UEFA’s financial fair play as a policy of anti-doping
2014
Against the backdrop of an increasing use of the term ‘doping’ in circumstances other than the classical understanding, this theoretic article provides a new and comprehensive inter-disciplinary reflection of the doping concept. The aim is to elaborate a broader understanding of doping in relation to socio-economic contexts. Besides addressing the question which structural similarities in general justify the label ‘doping’, a comparison between ‘classical’ doping and the so-called financial doping in European club football is developed. These insights serve as a basis for a consideration, to what extent insights of social-scientific research on drugs in sport may be consulted to analyse soc…
Project finance in the energy industry: new debt-based financing models
2012
The paper aims to examine the development of new financing models for project finance to attract private investors to finance large European energy infrastructure projects. In particular, the paper investigates the uniqueness of the project finance as a rapidly growing field in finance, the financial characteristics of the project bond market as one of the vehicles for funding energy projects, and the role of the credit support provided by the European Investment Bank and the European Union to promote the bond-based financing schemes. The paper is organized as follows. Section 1 provides a general description of project finance. Section 2 identifies the economic reasons for using project fi…
