AN EXPERIMENTAL WORKFLOW FOR THE VIRTUAL RECONSTRUCTION OF ANCIENT STATUES
2021
The work aims to investigate the main steps of a virtual reconstruction process of ancient statues, inspecting theoretical and technical approaches. Two fragmentary Roman statues from the "Sanctuary of Isis", inside the Archaeological Park of Lilibeo-Marsala (Italy), were chosen as a case study. Trying to preserve the original artwork authenticity and the transparency of the reconstruction method, a workflow was developed following three steps: 1) 3D survey and reality based model production; 2) evaluation of reconstruction hypotheses based on a rigorous selection of reference sources; 3) 3D modelling and source-based model creation. Three models for multiple visualization purposes were car…
Damping Provision by Different Virtual Synchronous Machine Schemes
2020
The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…
Sensitivity Analysis and Frequency Dynamics of Grid-Connected Converters with Virtual Inertia
2021
For the participation in the frequency control of the system, power converters can be controlled with different strategies and methods, sharing the common concept of virtual inertia capability. In this work, a sensitivity analysis of two main categories of converter controls with virtual inertia is presented. The considered schemes are a grid-following current vector control with additional virtual inertia block and a grid-forming control scheme based on virtual synchronous machine concept. A proper basis for the comparison is first assessed providing an analytical correlation between the control parameters of the two schemes. For the two control strategies, the sensitivity analysis of the …
Tiešsaistes spēles (ne)produktivitāte: gadījuma pētījums par radošumu
2022
Bakalaura pētījums “Tiešsaistes spēles (ne)produktivitāte: gadījuma pētījums par radošumu” fokusējās uz radošajiem procesiem, ko piedzīvo galda spēles Dungeons and Dragons spēlētāji veidojot virtuālās pasaules un veidiem kā radošums izpaužas, kad spēle ir situēta tiešsaistes vidē. Iesaistoties Dungeons and Dragons kopienā, izmantojot līdzdalīgu novērojumu, neformālas diskusijas un daļēji strukturētas intervijas, es pētu dažādus artefaktu veidošanās procesus un digitālo tehnoloģiju ietekmi uz mūsu socializāciju tiešsaistē. Radošums ir improvizēts un ir mūsu sociālās un kultūras dzīves neatņemama sastāvdaļa, kas veido gan mūs pašus, gan esošās struktūras.
Participation of the young ones in virtual worlds : A look at experiences and motivations
2011
Virtual worlds have become very popular and there have been some attempts to find the motivations and experiences of using them. The aim of this paper is to analyze the motivations and experiences of young ones to utilize virtual worlds. The paper identifies the activities that children perform in virtual worlds, features they use as well as the reasons for abandoning these virtual worlds. The paper presents results of a qualitative field study. The results indicate that features that are liked in the virtual worlds are similar to games. The most liked features for virtual worlds were developing characters and doing things in groups. The activities that were liked the most in virtual worlds…

Preventing reverse engineering of native and managed programs
2015
One of the important aspects of protecting software from attack, theft of algorithms, or illegal software use is eliminating the possibility of performing reverse engineering. One common method used to deal with these issues is code obfuscation. However, it is proven to be ineffective. Code encryption is a much more effective means of defying reverse engineering, but it requires managing a cryptographic key available to none but the permissible users. The thesis presents a system for managing cryptographic keys in a protected environment and supporting execution of encrypted code. The system has strong security guarantees. In particular, the cryptographic keys are never stored on the target…
Neuroeducación en virtudes cordiales. Una propuesta a partir de la neuroeducación y la ética discursiva cordial
2014
El tema de la tesis es proponer una educación en virtudes cordiales, fundamentadas en la obra de Adela Cortina, y llevar a cabo esa educación mediante un diseño educativo y pedagógico acorde con los últimos avances en neuroeducación. OBJETIVOS: El objetivo principal es demostrar la necesidad de educar en virtudes cordiales, que por ser procedimentales e ir dirigidas a regular una convivencia pacífica y buscar la justicia global, son universalizables y por tanto, asumibles por cualquier sujeto, sea cual sea su cultura de origen. Además, me propongo demostrar que un programa neuroeducativo es el tipo de educación idónea para este propósito. Para alcanzar este objetivo principal, me propongo v…
The features of the ethics of humor: A proposal from contemporary authors
2013
Destaco algunas de las aportaciones de autores contemporáneos que han abordado el tema del humor desde un punto de vista ético, principalmente: Ronald de Sousa, Joseph Boskin, John Morreall, Simon Critchley y Vittorio Hösle. Partiendo de su pensamiento, defiendo que la «ética del humor» tiene, al menos, las siguientes características: nos ayuda a reconocer los valores éticos en los que realmente creemos, detecta el humor éticamente incorrecto que mantiene estereotipos, fomenta el desarrollo de virtudes, critica los vicios de la sociedad contribuyendo a construir una sociedad más ética, y justifica con razones adecuadas la risa que trata de mejorar éticamente a la sociedad. I emphasize some …
Sport Ethics: The substantialist proposal of Lumpkin, Stoll and Beller, from ethical proceduralism
2013
En este artículo presento de forma crítica la propuesta de ética del deporte como «bolsa de virtudes» que elaboran tres autores estadounidenses que son Lumpkin, Stoll y Beller. Dicha propuesta debe entenderse como una manifestación de sustancialismo neoaristotélico en deporte, con una clara influencia de MacIntyre. Mi objetivo es mostrar cómo dicho sustancialismo no es suficiente para una propuesta ética del deporte, por lo que abogo por incorporar algunos de los presupuestos del procedimentalismo ético aplicado al deporte. In this article the author presents critically the proposed sports ethics as «bag of virtues» that Americans made three authors are Lumpkin, Stoll and Beller. This propo…
