(Institute of Electrical and Electronics Engineers (IEEE), 2018)Unmanned aerial vehicles (UAVs) are emerging as enablers for supporting many applications and services, such as precision agriculture, search and rescue, temporary network deployment or coverage extension, and security. ...
-
(Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2011)Presentamos Onoma, un conjugador en línea para conjugar y analizar tanto los verbos existentes como los neologismos verbales en español. Su desarrollo es el resultado de un importante trabajo lingüístico sobre el sistema ...
-
(Nature Research, 2017)Deep brain stimulation (DBS) for Parkinson’s disease is a highly effective treatment in controlling otherwise debilitating symptoms. Yet the underlying brain mechanisms are currently not well understood. Whole-brain ...
-
(ACM Association for Computer Machinery, 2017)The interplay between the response latency of web search systems and users’ search experience has only recently started to attract research attention, despite the important implications of response latency on monetisation ...
-
(Royal Society, 2022)In order to survive in a complex environment, the human brain relies on the ability to flexibly adapt ongoing behaviour according to intrinsic and extrinsic signals. This capability has been linked to specific whole-brain ...
-
(Karger (S. Karger AG), 2017)Objective: The aortic isthmus (AoI) blood flow has a characteristic shape with a small end-systolic notch observed during the third trimester of pregnancy. However, what causes the appearance of this notch is not fully ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2018)The purpose of this article is to bestow the reader with a timely study of UAV cellular communications, bridging the gap between the 3GPP standardization status quo and the more forward-looking research. Special emphasis ...
-
(Springer, 2015)Due to the dominance of the downlink traffic in Wireless Local Area Networks (WLANs), a large number of previous research efforts have been put to enhance the downlink transmission, namely, from the Access Point (AP) to ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2011)Measuring music similarity is essential for multimedia retrieval. For music items, this task can be regarded as obtaining a suitable distance measurement between songs defined on a certain feature space. In this paper, we ...
-
(Nature Research, 2022)Significant advances have been made by identifying the levels of synchrony of the underlying dynamics of a given brain state. This research has demonstrated that non-conscious dynamics tend to be more synchronous than in ...
-
(Springer, 2009)We prove that if C C RN is an open bounded convex set, then there is only one Cheeger set inside C and it is convex. A Cheeger set of C is a set which minimizes the ratio perimeter over volume among all subsets of C.
-
(Australasian Society for Computers in Learning in Tertiary Education, 2022)In recent years, universities have intensified their use of technologies and implemented various modes of flexible teaching. This study sought to demonstrate that students prefer flipped learning with combined forms of ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2021)This letter applies a feedforward neural network trained in an unsupervised fashion to the problem of optimizing the transmit powers in centralized radio access networks operating on a cell-free basis. Both uplink and ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2021)This letter applies a feedforward neural network trained in an unsupervised fashion to the problem of optimizing the transmit powers in cellular wireless systems. Both uplink and downlink are considered, with either ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2021)This letter proposes the unsupervised training of a feedforward neural network to solve parametric optimization problems involving large numbers of parameters. Such unsupervised training, which consists in repeatedly ...
-
(CEUR Workshop Proceedings, 2018)This paper describes the participation of the Web Science and Social Computing Research Group from the Universitat Pompeu Fabra, Barcelona (UPF) at CLEF 2018 eRisk Lab1. Its main goal, di- vided in two different tasks, is ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2020)This letter proposes respective policies for uplink power control and downlink power allocation in cell-free wireless networks. Both policies rely only on large-scale quantities and are expressed in closed form, being ...
-
(SAGE Publications, 2018)In this article, we introduce the method of urban association rules and its uses for extracting frequently appearing combinations of stores that are visited together to characterize shoppers’ behaviors. The Apriori algorithm ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2022)Automatic audio-visual urban traffic understanding is a growing area of research with many potential applications of value to industry, academia, and the public sector. Yet, the lack of well-curated resources for training ...
