Effects of functional endoscopic sinus surgery on the acoustics of the sinonasal tract
2017
Background: Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and corresponding 3D casts. Methodology: Nasal and paranasal cavities of formalin-preserved cadavers and corresponding 3D replicas were excited by sine tone sweeps from an earphone placed in the epipharynx.The response was picked up by a microphone at the nostrils. Different FESS procedures were performed and the a…
A General Fuzzy-Parsing Scheme for Speech Recognition
1985
In this paper a Speech Recognition Methodology is proposed which is based on the general assumption of ‘fuzzyness’ of both speech-data and knowledge-sources. Besides this general principle, there are other fundamental assumptions which are also the bases of the proposed methodology: ‘Modularity’ in the knowledge organization, ‘Homogeneity’ in the representation of data and knowledge, ‘Passiveness’ of the ‘understanding flow’ (no backtraking or feedback), and ‘Parallelism’ in the recognition activity.
Restricted Decontamination for the Imbalanced Training Sample Problem
2003
The problem of imbalanced training data in supervised methods is currently receiving growing attention. Imbalanced data means that one class is much more represented than the others in the training sample. It has been observed that this situation, which arises in several practical domains, may produce an important deterioration of the classification accuracy, in particular with patterns belonging to the less represented classes. In the present paper, we report experimental results that point at the convenience of correctly downsizing the majority class while simultaneously increasing the size of the minority one in order to balance both classes. This is obtained by applying a modification o…
Evolución jurisprudencial de la protección ante el discurso del odio en España en la última década
2012
El discurso de odio es un problema que en los últimos años está adquiriendo un alta relevancia, tanto en el plano internacional, como en el nacional. El aumento de la utilización de la libertad de expresión con el objetivo de legitimar la provocación a la xenofobia, en particular, en contra de minorías sociales, es una actitud que está poniendo en peligro la cohesión social de las sociedades actuales. Es por esto que aquí se estudia la jurisprudencia que diversos órganos han dictado en España, con el objetivo de observar cuál ha sido su evolución durante la última década. ABSTRACT. Hate Speech is an increasing problem that, in the last decade, is acquiring a special relevance, at both the i…
Automated Characterization of Mouth Activity for Stress and Anxiety Assessment
2016
International audience; Non-verbal information portrayed by human facial expression, apart from emotional cues also encompasses information relevant to psychophysical status. Mouth activities in particular have been found to correlate with signs of several conditions; depressed people smile less, while those in fatigue yawn more. In this paper, we present a semi-automated, robust and efficient algorithm for extracting mouth activity from video recordings based on Eigen-features and template-matching. The algorithm was evaluated for mouth openings and mouth deformations, on a minimum specification dataset of 640x480 resolution and 15 fps. The extracted features were the signals of mouth expa…
A simple algorithm for finding short sigma-definite representatives
2010
We describe a new algorithm which for each braid returns a quasi-geodesic sigma-definite word representative, defined as a braid word in which the generator sigma_i with maximal index i appears either only positively or only negatively.
Asymptotic bit frequency in Fibonacci words
2021
It is known that binary words containing no $k$ consecutive 1s are enumerated by $k$-step Fibonacci numbers. In this note we discuss the expected value of a random bit in a random word of length $n$ having this property.
A conversational, morpho-syntactic and intonation analysis of discourse markers in political discourse : A case study of presidential debates and tel…
2020
This thesis proposes a morphosyntactic, prosodic and conversational analysis of discourse markers in presidential debates and televised political talkshows in the United States of America. The main object of the study is the role of discourse markers in the sequential structuring and in the enunciative organisation of presidential debates in the United States of America. Discourse markers, in correlation with gestures and intonation, contribute significantly to the construction of the verbal exchange between the various participants in mediated political discourse. To achieve its goals, this thesis draws on several theoretical frameworks dealing with spontaneous speech (Benveniste and Berre…
Comparative study of David Lloyd George’s and Winston Churchill’s war speeches
2018
Comparative study of David Lloyd George’s and Winston Churchill’s war speechesAs objects of communication, even of propaganda, war speeches acquired a leading role in the 20th century thanks to the ideological values they carry and the impact they have, at the time of mass communication. As an ancient art, public speaking obeys the rules of rhetoric, so as to best convey a message, which, in wartime, might prove decisive.Two worldwide conflicts in which democratic powers faced authoritarian regimes occurred last century. If democracies eventually won, their political systems had to evolve, temporarily, thanks to the emergence of charismatic leaders. This thesis aims to study the war speeche…
Le dénigrement de l’autre par le biais de la langue. Une étude pilote dans le domaine du foot en France.
2015
International audience; This article presents an exploratory study that aims to link social sciences, linguistics and sport. Based on the group-focus enmity concept which focuses on existing depreciations among individuals due to their alleged affiliation to a specific social group, we ask how theses alleged social groups treated like entities are concretely devaluated by using words, especially in highly competitive fields like sport. Even this innovative concept is a fundamentally open concept into which further elements can be integrated, we focus on 5 key elements: racism and xenophobia (1), anti-semitism (2), homophobia (3), sexism (4) and anti-capitalism (5). Even this article can onl…
