Social-aware Opportunistic Routing Protocol based on User's Interactions and Interests
Nowadays, routing proposals must deal with a panoply of heterogeneous
devices, intermittent connectivity, and the users' constant need for
communication, even in rather challenging networking scenarios. Thus, we
propose a Social-aware Content-based Opportunistic Routing Protocol, SCORP,
that considers the users' social interaction and their interests to improve
data delivery in urban, dense scenarios. Through simulations, using synthetic
mobility and human traces scenarios, we compare the performance of our solution
against other two social-aware solutions, dLife and Bubble Rap, and the
social-oblivious Spray and Wait, in order to show that the combination of
social awareness and content knowledge can be beneficial when disseminating
data in challenging networks
Impact of COVID-19 outbreak on rehabilitation services and Physical and Rehabilitation Medicine physicians' activities in Italy An official document of the Italian PRM Society (SIMFER)
Since the onset of the COVID-19 outbreak in Europe,
Italy has been among the first affected countries, and the
number of reported cases is still the highest in the continent.
Since the beginning, the epidemic has had a huge impact in the acute sector of the healthcare system (especially
the emergency departments, Intensive Care Units (ICUs),
laboratory and imaging services), and these services have
been experiencing increasing pressur
Increasing the Transparency, Accountability and Controllability of multi-domain networks with the UPIN framework
Demands for a more trustworthy Internet are constantly increasing, in particular to support emerging critical services such as intelligent urban transport systems and smart energy grids. Such cyber-physical systems require more insight into the properties of network operators (e.g., in terms of the security posture of their equipment) and more control over which network operators transport their data, thus going well beyond the traditional security paradigm which the Internet security community currently focuses on (confidentiality, availability, and integrity). In this work-in-progress paper we propose the UPIN framework, which aims to fulfill these new trust requirements. The framework advances the state-of-the-art by defining components needed to incorporate transparency, accountability, and controllability into the Internet or other types of inter-domain networks. The framework is based on our analysis of a smart grid use case to understand the specific needs of critical service providers and a literature study on existing technologies. We also discuss our ongoing work, and the demands and challenges of implementing and deploying the UPIN framework
IR thermography applied to flash experiments of semitransparent TBCs
Abstract Thermal Barrier Coatings (TBC) are applied to protect components of gas turbines from high temperature of combustion gases. ZrO 2 , the material mainly used in TBCs, is semitransparent to near IR radiation that is typically delivered by the laser in the laser flash equipment and also radiated at working temperatures that are grater than 1000 °C. Thermography and radiometers are utilized to measure thermal diffusivity of TBCs. Discussion is done on the countermeasures to obtain correct results in case of semitransparency
