Cube Complexes and Virtual Fibering of 3-Manifolds.

Una 3-varietà si dice virtualmente fibrata se ammette un rivestimento finito che è un fibrato con base una circonferenza e fibra una superficie. In seguito al lavoro di geometrizzazione di Thurston e Perelman, la generica 3-varietà risulta essere iperbolica; un recente risultato di Agol afferma che una tale varietà è sempre virtualmente fibrata. L’ingrediente principale della prova consiste nell’introduzione, dovuta a Wise, dei complessi cubici nello studio delle 3-varietà iperboliche. Questa tesi si concentra sulle proprietà algebriche e geometriche di queste strutture combinatorie e sul ruolo che esse hanno giocato nella dimostrazione del Teorema di Fibrazione Virtuale.

Una panoramica sulle agenzie di traduzione: caratteristiche, tipologie e flussi di lavoro

Over the last decades the need for translation and interpreting services has increased thanks to globalization and to the progress made in the technology field. However, the organizations which provide these services, the so-called translation agencies or translation companies, are still underrated and, in some cases, virtually unknown to those people who do not belong to the translation market. The present work aims to answer all the most common questions about these companies by describing in as much detail as possible all their aspects, mechanisms, workflows and characteristics. Chapter one introduces translation agencies outlining, in the first place, some of their main definitions and classifications. Particular attention is also devoted to the translation market, to the main trade associations in the field, to the quality standards adopted and to the important role played by social media for the success of translation agencies. Chapter two starts with a theoretical introduction to the concept of “organization” and an examination of the main types of teams commonly adopted in companies, i.e. virtual and traditional. This introduction is then followed by an analysis of the typical workflows taking place in translation agencies, the main professionals involved (such as Project Managers, translators and reviewers) and their essential competences. Finally, chapter three presents a comparison between a traditional translation agency, i.e., Going Green Translations, characterized by a physical office and internal collaborators, and a more innovative translation agency, Qabiria, which on the contrary relies on a completely decentralized team. The interviews have allowed me to highlight similarities and differences as well as advantages and disadvantages of these agencies and their teams. The chapter concludes with a personal commentary on what has emerged from the comparison, and on the future of translation companies.

HBIM to Virtual Reality Workflow for Industrial Archaeology Immovable Assets’ Management: A Case Study

As a witness on the industrialization in Bologna, since its first generation was born in the late 1760, the Battiferro lock has been coping with the innovation that the city experienced throughout the centuries, until it has lost its functionality due to the technological development for which Bologna’s canals were gradually covered starting from the 1950s under Giuseppe Dozza ’s administration, as part of the reconstruction, reclamation and urban requalification that was carried out in the aftermath the World War II and which involved the whole city. The interest of the research carried out on this case study was primarily to reintroduce the landmark that is still intact, to what is considered to be the fourth generation of the industrial revolution, namely in the construction field, which is recognized as Construction 4.0, by means of the Historic (or Heritage) Information Modeling HBIM and Virtual Reality (VR) application. A scan-to-BIM approach was followed to create 3D as-built BIM model, as a first step towards the storytelling of the abandoned industrial built asset in VR environment, or as a seed for future applications such as Digital Twins (DT), heritage digital learning, sustainable impact studies, and/or interface with other interfaces such as GIS. Based on the HBIM product, examples of the primary BIM deliverables such as 2D layouts is given, then a workflow to VR is proposed and investigated the reliability of data and the type of users that may benefit of the VR experience, then the potential future development of the model is investigated, with comparison of a relatively similar experience in the UK.
