Social Virtual Reality (VR) allows multiple distributed users getting together in shared virtual environments to socially interact and/or collaborate. This article explores the applicability and potential of Social VR in the broadcast sector, focusing on a live TV show use case. For such a purpose, a novel and ligh…
Leadership in virtual teams: a comparison of transformational and transactional leaders
2009
The effects of transactional and transformational leadership on groups in which people interact in a virtual manner were analyzed and specifically the level of satisfaction and perception of the style adopted were evaluated. Results indicated that a transformational style is more satisfying than a transactional style, and that a transformational leader is judged to be better than a transactional leader.

Implementing cloud ERP solutions: a review of sociotechnical concerns
2018
Abstract Cloud ERP solutions allow organizations of all sizes to support and coordinate key business processes by leveraging virtualization. Nevertheless, the implementation of cloud ERPs is not straightforward and there are significant issues that need to be taken into account when launching cloud ERP initiatives. To explore these issues, we conducted an in-depth systematic review of related research literature. We identified six key issues related to cloud ERP implementation: a) functionality fit, b) integration, c) data migration, d) organizational change, e) data security, and f) reliability. Furthermore, we mapped these issues to the different sizes of organizations. Based on this revi…
Tuning Java to Run Interactive Multiagent Simulations over Jason
2010
Java-based simulation environments are currently used by many multiagent systems (MAS), since they mainly provide portability as well as an interesting reduction of the development cost. However, this kind of MAS are rarely considered when developing interactive applications with time response constraints. This paper analyses the performance provided by Jason, a well-known Java-based MAS platform, as a suitable framework for developing interactive multiagent simulations. We show how to tune both the heap size and the garbage collection of the Java Virtual Machine in order to achieve a good performance while executing a simple locomotion benchmark based on crowd simulations. Furthermore, the…
The hyplet : Joining a Program and a Nanovisor for real-time and Performance
2020
This paper presents the concept of sharing a hyper-visor address space with a standard Linux program. In this work, we add hypervisor awareness to the Linux kernel and execute code in the HYP exception level through using the hyplet. The hyplet is an innovative way to code interrupt service routines and remote procedure calls under ARM. The hyplet provides high performance and run-time predictability. We demonstrate the hyplet implementation using the C programming language on an ARM8v-a platform and under the Linux kernel. We then provide performance measurements, use cases, and security scenarios. peerReviewed
Nuove ricerche a Solunto (2021)
2021
New researches in Solunto (2021) · The paper presents an overview of the ongoing researches in Solunto by the University of Palermo. In 2021 stratigraphical sondages were undertaken in two areas of the town: 1) in the great sanctuary above the theatre, in the frame of a major project aimed at addressing several still unresolved issues. That area, as a matter of fact, has never been considered as a whole; the sacred buildings have not been studied, and their mutual relationships and the links with the adjacent terraces have never been properly examined; 2) in the North Baths near the agora, as a corollary of the systematic study of water management, some sondages were made by G. Polizzi. Fin…
Study of 3D sound for an audio-visual interaction in enriched virtual environment
2011
Most of the applications integrating 3D sound in virtual environment are limited to acoustic simulation. The objective of this thesis is to study the added value of 3D sound in the interaction with virtual environment. We developed an audio stimulation technique called "Artificial Spatial Audio Sensation: (ASAS)" based on the creation of audio effects. This technique conveys the sensations of spatialized sound that allows accurate sound source localization in azimuth and in elevation. In order to improve the localization time we also developed a model that integrates Head-Related Transfer Function (HRTF) with the ASAS technique. For the simulation of the depth of spatial sound sources, we d…
