Recent Submissions
-
(Springer, 2022)The Bitcoin P2P network currently represents a reference benchmark for modern cryptocurrencies. Its underlying protocol defnes how transactions and blocks are distributed through all participating nodes. To protect user ...
-
(Wiley, 2021)To make sense of ambiguous and, at times, fragmentary sensory input, the brain must rely on a process of active interpretation. At any given moment, only one of several possible perceptual representations prevails in our ...
-
(Elsevier, 2021)Recently, a lot of attention has been focused on the incorporation of 3D data into face analysis and its applications. Despite providing a more accurate representation of the face, 3D facial images are more complex to ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2022)In this article, we present the software tools we have implemented to bring complex privacy technologies closer to developers and to facilitate the implementation of privacyenabled blockchain applications
-
(Elsevier, 2021)A considerable body of research deals with the automatic identification of hate speech and related phenomena. However, cross-dataset model generalization remains a challenge. In this context, we address two still open ...
-
(Elsevier, 2021)Acoustic changes linked to natural prosody are a key source of information about the organization of language. Both human infants and adults readily take advantage of such changes to discover and memorize linguistic patterns. ...
-
(Springer, 2021)This paper studies the relativistic angular momentum for the generalized electromagnetic field, described by r-vectors in (k, n) space-time dimensions, with exterioralgebraic methods. First, the angular-momentum tensor is ...
-
(Elsevier, 2021)This work proposes an efficient example-based photorealistic style transfer algorithm for video. Given a source unprocessed video and a reference image color graded by an artist, we describe an automatic algorithm to ...
-
(Springer, 2021)Research on speech technologies necessitates spoken data, which is usually obtained through read recorded speech, and specifically adapted to the research needs. When the aim is to deal with the prosody involved in speech, ...
-
(Springer, 2021)Over the past decade, the Bitcoin P2P network protocol has become a reference model for all modern cryptocurrencies. While nodes in this network are known, the connections among them are kept hidden, as it is commonly ...
-
(Springer, 2021)This study extends the previous research in which it has been shown that a mixed reality (MR) system fosters social interaction behaviours (SIBs) in children with Autism Spectrum Condition (ASC). When comparing this system ...
-
(SCITEPRESS – Science and Technology Publications, 2022)Piano is one of the most popular instruments among music learners. Technologies to evaluate piano performances have been researched and developed in recent years rapidly, including data driven methods using machine learning. ...
-
(American Physical Society, 2022)The severe neurological disorder epilepsy affects almost 1% of the world population. For patients who suffer from pharmacoresistant focal-onset epilepsy, electroencephalographic (EEG) recordings are essential for the ...
-
(ACM Association for Computer Machinery, 2022)Music listening in today’s digital spaces is highly characterized by the availability of huge music catalogues, accessible by people all over the world. In this scenario, recommender systems are designed to guide listeners ...
-
(MDPI, 2021)Zero-Knowledge Proofs (ZKPs) are cryptographic primitives allowing a party to prove to another party that the former knows some information while keeping it secret. Such a premise can lead to the development of numerous ...
-
(MDPI, 2022)Nowadays, there are a plethora of services that are provided and paid for online, such as video streaming subscriptions, car-share, vehicle parking, purchasing tickets for events, etc. Online services usually issue tokens ...

(Institute of Electrical and Electronics Engineers (IEEE), 2021)This paper formulates regularized zero-forcing (RZF) precoders that are both network- and user-centric for the downlink of centralized radio-access networks operating in a cell-free fashion. The transmission to every user ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2021)This paper tackles the problem of zero-forcing (ZF) precoding for the downlink of centralized radio-access networks operating in a cell-free fashion. While the customary workhorse of ZF precoding is the channel pseudo-inverse, ...
