This paper summarizes the adoption of new technologies in the Archaeological Museum of Thessaloniki, Greece. RFID technology has been adopted. RFID tags have been attached to the artifacts. This allows for several interactions, including tracking and automated registering of movements of exhibits, personnel and visitors inside the museum, location-dependent guided tours and more. Furthermore, a prototype RFID-enabled social robot has been designed and constructed. The robot includes several possibilities of interaction with the environment and the visitors, allowing for the development of different applications. In this context, the robot plays treasure-games with younger visitors, benefiting from oral, touch and RF interactions. It also joins conversations with the visitors around the exhibits, exploiting artificial intelligence, giving information on the exhibits., {"references":["CultureId – Project.

Summarization: This article presents European-based contributions for wireless power transmission (WPT), related to applications ranging from future Internet of Things (IoT) and fifth-generation (5G) systems to high-power electric vehicle charging. The contributors are all members of a European consortium on WPT, COST Action IC1301. WPT is the driving technology that will enable the next stage in the current consumer electronics revolution, including batteryless sensors, passive RF identification (RFID), passive wireless sensors, the IoT, and machine-to-machine solutions. The article discusses the latest developments in research by some of the members of this group. Presented on: IEEE Microwave Magazine

Summarization: A scheme for automated planning of passive RFID network is proposed. The scheme comprises two parts. The first part creates a fast site-specific probabilistic propagation model for successful identification from the reader of any possible tag antenna. The materials of surrounding walls as well the tag antennas radiation pattern, the geometry and the polarization of both reader and tag are taken into account. In the second part, a hybrid form of particle swarm optimization (PSO) algorithm is applied. The proposed approach selects a subset of tag antenna configurations to be installed so that a given cost function is satisfied. By clustering problematic areas during each iteration and moving the swarms towards them, we imitate the acts of a human-planner. The combinatorial performance of all active readers is evaluated at each tag location; this reveals that good identification performance is recorded at overlapping regions, where no single reader- tag antenna operates adequately. The proposed clustering approach greatly improves the convergence-time of the standard PSO and greatly reduces equipment, cutting down the cost of the network accordingly. Comparison with standard PSO reveals that the overall equipment can be reduced by a factor of two, satisfying the same quality constraints.
