Immersive Virtual Reality Education Application : Four Development Iterations along Design Science Research Methodology
2022
This study introduces a research and development process of an immersive Virtual Reality (VR) education application. Altogether four application development iterations are showcased along the Design Science Research methodology. The results show how initial problems change and new problems occur during the course of a long-term DSR project with multiple iterations. Moreover, the study results confirm various previous findings, for example, that VR works better on higher learning levels such as application -level and personalization is a way to achieve this. In addition, 360 photos and videos were found to be easy and cost-efficient ways to increase personalization of VR applications. The re…
On the History of Differentiable Manifolds
2012
International audience; We discuss central aspects of history of the concept of an affine dif-ferentiable manifold, as a proposal confirming the need for using some quantitative methods (drawn from elementary Model Theory) in Mathematical Historiography. In particular, we prove that this geometric structure is a syntactic rigid designator in the sense of Kripke-Putnam.
Formaciones sociales y opresión en Marx
2018
The text explains the difference between Marx?s concept of «oppression» and others as «coercion» by Durkheim or «domination» by Weber. The article then establishes, in a methodical way, the centrality of a passage from Capital, in which three different theories on «oppression» appear. It?s explained that two of them are rather a philosophical antinomy. The other, relative to the heteronomy of social time, can be completed by defining the heteronomy of social space, which gives it analytical virtuality. Some examples are given.

Hypervisor-assisted Atomic Memory Acquisition in Modern Systems
2019
Reliable memory acquisition is essential to forensic analysis of a cyber-crime. Various methods of memory acquisition have been proposed, ranging from tools based on a dedicated hardware to software only solutions. Recently, a hypervisor-based method for memory acquisition was proposed (Qi et al., 2017; Martignoni et al., 2010). This method obtains a reliable (atomic) memory image of a running system. The method achieves this by making all memory pages non-writable until they are copied to the memory image, thus preventing uncontrolled modification of these pages. Unfortunately, the proposed method has two deficiencies: (1) the method does not support multiprocessing and (2) the method does…

The Blog, the Blogger and the Other on the Net
2008
This work describes a qualitative research, still in progress, about blogging. This experience is fully linked to the concept of "social presence": users feel "to be there" in the virtual environment. From a brief review of researches about blogging, we propose a work that, through a semi-structured interview (submitted on line), could analyze the mental representations of bloggers. Moreover, we have the purpose to read these impressions through a key pattern of interactions between blog, blogger and other users. The primary goal of this study, still preparatory, is to explore the psychological means of blogging.
Soluzioni innovative nell’e-learning: l’insegnante “in ruolo” nelle comunità virtuali.
2012
Un settore dinamico nella ricerca educativa è quello relativo alla correlazione tra la formazione degli insegnanti, la progettazione del sillabo e i risultati conseguiti dagli studenti. Alla luce dei recenti comportamenti sociali emergenti, in questo saggio si analizza la figura dell’insegnante nella progettazione degli ambienti di formazione online. Superando i limiti del Virtual Learning Environment (VLE) e le criticità del Personal Learning Environment (PLE) si focalizza l’attenzione sul concetto di person in place, che vive esperienze formative in luoghi densi di relazioni sociali e tecnologicamente arricchiti. Oggi le tecnologie permettono la creazione di ambienti di apprendimento cara…
Development of Network Security Education
2021
Distance education has grown tremendously over the last decade. Internet technologies have enabled a large-scale dispensation of lectures, exercises, and training. Virtual Learning Management Systems (LMSs) offer a number of tools to realize distance education and distance learning. In this work, we present a virtual system architecture for training cyber security professionals with hands-on skills. The architecture is based on a VirtualBox virtualization environment. Guest machines are installed on an instance of VirtualBox. The installed environment offers a safe and isolated workbench for experiments. After installation and configuration of the environment, students perform a number of i…
