In this paper we discuss the exploitation of data originated from Bluetooth-enabled devices to understand visitor’s behaviour in the Louvre museum in Paris, France. The collected samples are analysed to examine frequent patterns in visitor’s behaviours, their trajectory, length of stay and some relationships, offering new details on behaviour than(More)
Museums often suffer from so-called “hyper-congestion”, wherein the number of visitors exceeds the capacity of the physical space of the museum. This can potentially deteriorate the quality of visitor’s experience disturbed by other visitors’ behaviors and presences. Although this situation can be mitigated by managing visitors’ flow between spaces, a(More)
Adsorption of the organic sulfur compounds thiophene (TP) and 1-benzothiophene (1-BTP) in an organic model solution of hydrodesulfurizated gasoline (heptane with 1 wt% toluene and 0.156 mM (5 ppmw as sulfur) TP or 1-BTP) was studied by a batch method at 80 degrees C using metal-ion-exchanged Y-zeolites. Although NaY-zeolite or its acid-treated material(More)
Ce(IV)-loaded Y-zeolites (CeY) were prepared for selective removal of the trace amount of organic sulfur compounds from hydrodesulfurization (HDS)-treated diesel oil. The CeY samples can be obtained from NH4-Y-zeolite (NH4Y) using liquid-phase ion-exchange and solid-state ion-exchange methods. The ion-exchange reactions, structures, and selective(More)
In this article we analyze how the privacy issue will affect in the deployment and design of Networking Robots in European urban areas. Privacy means the way to guarantee self control on private data that can be processed by the Networked Robots. We start analyzing the technical capabilities of networked robots in public and private spaces, the legal(More)
