(Institute of Electrical and Electronics Engineers (IEEE), 2014)A frequency agile Vivaldi antenna whose operating frequency band can be switched is pro- posed. High-performance radio-frequency micro- electromechanical system (RF-MEMS) switches al- low tuning of the operational band ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2017)This article proposes a novel liquid switch to reconfigure the operating frequency of a frequency-independent antenna. A Vivaldi antenna using a low-cost GaAs MMIC RF switch is used as a landmark to compare the measured ...

(CEUR Workshop Proceedings, 2018)The frequent use of Emojis on social media platforms has created a new form of multimodal social interaction. Developing methods for the study and representation of emoji semantics helps to improve future multimodal ...
-
(2016)Lexical taxonomies are tree or directed acyclic graph-like structures where each node represents a concept and each edge encodes a binary hypernymic (is-a) relation. These lexical resources are useful for AI tasks like ...
-
(Springer, 2015)Hypernym extraction is a crucial task for semantically motivated NLP tasks such as taxonomy and ontology learning, textual entailment or paraphrase identification. In this paper, we describe an approach to hypernym extraction ...
-
(Folk Music Analysis, 2018)This work deals with the automatic transcription and characterization of flamenco guitar, with a focus on short melodic interludes improvised between sung verses. These are called falsetas in the flamenco argot and are ...
-
(Association for the Advancement of Artificial Intelligence (AAAI), 2012)It has been shown recently that the complexity of belief tracking in deterministic conformant and contingent planning is exponential in a width parameter that is often bounded and small. In this work, we introduce a new ...
-
(Association for the Advancement of Artificial Intelligence (AAAI), 2012)In the presence of non-admissible heuristics, A* and other best-first algorithms can be converted into anytime optimal algorithms over OR graphs, by simply continuing the search after the first solution is found. The ...

(2018)Choir singers synchronize their fundamental frequency (f0) and timing when they perform together. In this work, we investigate several expressive characteristics of choir singing, with special emphasis on unison ...
-
(ACM Association for Computer Machinery, 2017)This paper presents a method for recognizing musical instruments in user-generated videos. Musical instrument recognition from music signals is a well-known task in the music information retrieval (MIR) field, where current ...
-
(International Speech Communication Association (ISCA), 2017)We present a new model for singing synthesis based on a modified version of the WaveNet architecture. Instead of modeling raw waveform, we model features produced by a parametric vocoder that separates the influence of ...

(International Research Council on Biomechanics of Injury (IRCOBI), 2018)The causes of intervertebral disc (IVD) ruptures continue to elude both biomechanists and clinicians. It is widely accepted that unique traumatic high‐load impacts are unlikely to lead to isolated IVD herniation. Therefore, ...
-
(International Research Council on Biomechanics of Injury (IRCOBI), 2014)National accident statistics in European countries as well as in many other countries are based on data recorded by the police. Generally, such data also include police reported estimates of the injury severity of accident ...
-
(ACL (Association for Computational Linguistics), 2018)Human language has evolved towards newer forms of communication such as social media, where emojis (i.e., ideograms bearing a visual meaning) play a key role. While there is an increasing body of work aimed at ...
