The paper illustrates a software architecture allowing a robot to socially interact with human beings, sharing with them some basilar cognitive mechanisms. Robust sensing of the environment and people is strongly linked with an artificial somatosensory system that drives the robot behavior at a low level and influences its motivation. Both long-term memory and short-term memory store relevant data to detect and recognize the social context (and social practice), and the human social behavior. Using both internal and external evaluations, the robot learns and improves its social skills, which take into account its physiological and emotional demands (affiliation, competence, certainty). Social interaction is encoded in the cognitive architecture by considering at the same level the human understanding and the robot communicative actions. This is done by using the same interaction channels (both verbal and nonverbal). Some examples derived from previous works show the effectiveness and the potential of the cognitive architecture.

In this paper we present an original contribution for the development of the wireless power transfer technology in the avionic environment. Flexible ferrites are proposed for the shielding structures of the transmitting and receiving coils to meet mechanical vibration, size and weight constrains for the aircraft onboard applications. A suitable analysis by means the design centering approach is presented and discussed to propose an useful approach for the wireless power transfer devices optimization.

The work deals with introduction of GNSS (Global Navigation Satellite System) technology into the railway sector. Particularly, since the requirements imposed by the railway environment are stringent, the use of an external mean for providing integrity monitoring and augmentation is highly recommended. In this paper, we show an algorithm based on GNSS code double differences to identify and exclude multiple satellite faults by using data acquired by multiple reference stations. The simulations results carried out in this framework are presented in terms of detection probability and false alarm rate.

In this paper, we propose to reconsider the myth of the paperless office and we explore a new user experience, the augmented document, in order to digitize a document, extract information (like scientific network) in order to find similar content. This framework exploits image processing tools to segment the document and facilitate the manipulation of its structure. Then, OCR is performed to enable textual edition: copy/paste from other sources, correct mistakes, change text box shapes. Moreover, in order to help the user enriching the document, the system is able to propose similar content (like papers from the same researcher, documents from the same topic …). This all-in-one framework was tested on many different devices like interactive table, HP Sprout, or Microsoft Surface, and all the actions can be performed with basic gestures without requiring technical expertise.

In this work an indoor position estimation algorithm will be proposed. The position will be measured by means of a sensor network composed by fixed beacons placed on the indoor environment and a mobile beacon mounted on the object to be tracked. The mobile beacon communicates with all the fixed beacons by means of ultra wide-band signals, and the distance between them is computed by means of time of flight techniques. Moreover, inertial measurements will be used when the position measurements are not available. Two main problems will be considered in the proposed architecture: the fact that the beacons work with a lower update rate than the IMU, and that the mobile beacon can comunicate with only one fixed beacon at a time. Experimental results will be shown in order to validate the effectiveness of the proposed technique.

The present work shows the results of a performance analysis for evaluating the impact of spoofing on GNSS Integrity for transport applications. Spoofing represents a potential risk to be managed for GNSS safety-related land mobile applications. To this aim a Virtual Test Bed has been generated. A rover receiver has been developed through an SDR, and relevant spoofed signal injected through a hardware simulator. A performance analysis software simulator performed relevant integrity study. Stanford plots have been generated for analyzing integrity performance to guarantee a THR=10-9/h in DGNSS mode.

The Nonnegative Matrix Factorization (NMF) approximates a large nonnegative matrix as a product of two significantly smaller nonnegative matrices. Because of the nonconvexity of the constrained optimization problem of finding the best approximation, all current algorithms are iterative and optimize the two factor matrices alternatingly. The resulting sublinear convergence rates give rise to the demand for parallel implementations on high performance computers. One of the best algorithms for NMF in terms of convergence is the Hierarchical Alternating Least Squares (HALS) algorithm. While other Alternating Nonnegative Least Squares (ANLS) algorithms have been shown to have a rather straight-forward parallelization because of independent matrix rows and columns, the row and column updates in HALS must be strictly consecutive, which is more difficult to parallelize. We show that a parallelization strategy similar to ANLS parallelizations exists and yields good speedups for up to 64 processes and satisfactory beyond. These are competitive in comparison to previous solutions to the problem. To our knowledge, HALS has not been parallelized before.

Since 2016 the fracture of the Larsen-C ice shelf has been regularly observed in the Eastern Weddell Sea (68°S, 61°W, Antarctica). This process led to the final collapse in July 2017, when an area of about 6000 km2 (i. e., about 9-12% of the whole shelf) was lost. In this study the resulting calved iceberg, termed as “A-68” from the U. S. National Ice Center, is observed using multi-frequency and multi-polarization Synthetic Aperture Radar (SAR) satellite platforms that include L-band Alos PaISAR-2, C-band Sentinel-l and X-band COSMO-SkyMed. A large set of SAR scenes were considered, collected in ScanSAR imaging modes over a time span of about 1 year, to analyze the iceberg properties and its melting process and drifting.

This paper investigates the uncertainty associated to Synthetic Aperture Radar method for UHF-RFID tag positioning in open storage yard or container port. Phase measurements are acquired during the flight of an unmanned aerial vehicle (UAV) equipped with UHF -RFID reader and antenna in outdoor scenario. The method requires for the knowledge of the reader antenna trajctory which is achieved with a Global Navigation Satellite System on the UAV. The uncertainty associated to the UAV trajectory measurements and to the RFID measurements are investigated. Localization performance is demonstrated by an experimental analysis in real outdoor scenario.
