Full textSe realizó un experimento usando datos acústicos, electropalatográficos y electoglotográficos simultáneos. Las secuencias estudiadas son de 4 tipos:
1) Secuencias de obstruyentes donde C1 es fonológicamente sorda y C2 es fonológicamente sonora.
2) Secuencias de obstruyentes donde C1 es fonológicamente sonora y C2 es fonológicamente sorda.
3) Secuencies de sonorante seguida de obstruyente.
4) Secuencias de obstruyente seguida de sonorante.
Se observó que en las secuencias de obstruyentes en catalán los hablantes tienden a anticipar el gesto de sonoridad de C2 a C1, tanto en las secuencias de oclusivas como en las secuencias de fricativa seguida de oclusiva. Así, el proceso es regresivo y categórico, lo cual es congruente con la existencia de una regla de asimilación de sonoridad en catalán. También se observó que los hablantes catalanes pueden mostrar anticipación parcial del gesto de sonoridad de C2, lo cual muestra que la asimilación de sonoridad puede ser un proceso gradual en catalán. Así pues, parece que la regla de asimilación de sonoridad es opcional. Los datos del catalán reflejan dos procesos distintos: por un lado, la asimilación completa y regresiva de sonoridad en las secuencias de obstruyentes es el resultado de una regla que implica la reorganización a alto nivel de las instrucciones motoras. Por otro lado, los casos de asimilación parcial podrían ser debidos a factores de implementación fonética.
En inglés se observó que no existe una regla fonológica de asimilación de sonoridad en las secuencias de obstruyentes. La coordinación de los gestos orales y glotales durante la constricción máxima es un proceso gradual.
En las secuencias que combinan sonorantes y obstruyentes, el gesto de sonoridad coincide con la transición de C1 a C2 en ambas lenguas. Además, se observa que puede haber asimilación completa de sonoridad en las secuencias obstruyente - sonorante en catalán. Esto sugiere que la regla de asimilación regresiva de sonoridad podría extenderse a este tipo de secuencias, por lo menos en algunos hablantes catalanes.
Finalmente, se sugiere que los modelos conocidos como Articulatory Phonology y Windows Theory pueden dar cuenta de la coordinación de los gestos orales y glotales en catalán e inglés.
The present study intends to analyze the process of voicing assimilation across different speaking rates in Catalan and English. More specifically, it aims at observing and characterizing voicing assimilation when two consonants that have a different phonological specification for voicing co-occur across word boundaries. Furthermore, this study intends to evaluate current descriptive frameworks, in order to see how they account for the data obtained in the experiment.
An experiment was carried out using simultaneous acoustic, electroglottographic and electropalatographic data. The sequences were of 4 types:
1) Obstruent sequences where C1 was phonologically voiceless and C2 was phonologically voiced, e.g., 'fat gap', 'this doll'.
2) Obstruent sequences where C1 was phonologically voiced and C2 was phonologically voiceless, e.g., 'sad gap', 'his toll'.
3) Sequences of sonorant plus voiceless obstruent, e.g., 'full cap', 'long sip'.
4) Sequences of voiceless obstruent plus sonorant, e.g., 'thick lap', 'this nut'.
It was found that in Catalan obstruent sequences that differ in their phonological specification for voicing, speakers tend to anticipate the voicing gesture of C2 to C1, both in stop sequences and in fricative - stop sequences. Thus, the process is regressive and categorical, which is congruent with a rule of voicing assimilation in Catalan. Evidence was also found that speakers can display partial anticipation of the voicing gesture of C2, which shows that voicing assimilation may also be a gradient process in this language. Thus, the voicing assimilation rule seems to be optional. The Catalan data thus seem to reflect two different processes. On one hand, complete regressive voicing assimilation in obstruent sequences seems to be the result of a rule involving higher-level reorganization of motor commands. On the other hand, cases of partial assimilation may result from phonetic implementation factors.
In English, it was found that there is no phonological rule of voicing assimilation in obstruent sequences. Rather, the coordination of oral and glottal gestures during the maximal constriction is a gradient process that may result from anticipatory overlap - sensitive to time constraints - and inertial effects .
In sequences of consonants where nasals and laterals combine with obstruents, the voicing gesture seems to be switched at the transition from C1 to C2 in both languages. In addition, evidence was found for complete assimilation of voicing in Catalan obstruent - sonorant sequences, suggesting the extension of the regressive voicing assimilation rule for obstruents to these sequences, at least for some speakers.
Finally, it is suggested that Articulatory Phonology and Keating's Windows Theory account for the coordination of oral and glottal gestures in Catalan and English.

Full textL'assimilation d'ensemble utilise une méthode de Monte-Carlo pour estimer les covariances d'erreur du moment qui permettent le transfert d'information des variables observées aux variables corrélées à celles-ci. Puisque les vents sont très peu observés dans la stratosphère et que les modèles y présentent des biais, la possibilité de contraindre l'état dynamique du modèle par l'assimilation d'observations de température et d'ozone par la technique d'ensemble est tentée. L'applicabilité de l'assimilation d'ensemble dans un système chimique/dynamique couplé est testé lors d'une expérience idéalisé (modèle parfait) de simulation de système d'observation avec le modèle de chimie-climat IGCM-FASTOC. La localisation des covariances est indispensable à la stabilité du système d'assimilation avec filtre de Kalman d'ensemble (EnKF) et les paramètres optimaux offrent une forte contrainte sur l'état dynamique global du modèle lorsque l'on assimile des observations satellites synthétiques de température et d'ozone stratosphériques uniquement. Le couplage entre l'ozone, la température et les vents est étudié dans le système EnKF optimisé. Les observations de température et d'ozone stratosphériques créent des incréments dynamiques bénéfiques lors des phases d'analyses. Il y a également une rétroaction lors de la phase de prédiction du système d'assimilation de données, qui aide à contraindre davantage les états chimiques et dynamiques globaux. L'impact potentiel de l'assimilation de données postérieures au temps d'analyse en mode multivarié est estimé avec un lisseur d'ensemble de Kalman (EnKS). L'assimilation d'observations additionnelles asynchrones, ayant jusqu'à 48 heures d'écart avec le temps d'analyse, offre des améliorations aux analyses de l'EnKF presque équivalentes à celles obtenues par assimilation d'une quantité égale d'observations additionnelles synchrones. L'EnKS présente des impacts bénéfiques sur l'état d'analyse des variables non observées mais des impacts mitigés sur l'état analysé des variables observées. La capacité de contraindre les vents stratosphériques non-observés grâce à l'assimilation d'observations d'ozone est démontrée dans le système d'assimilation d'ensemble avec l'EnKF et l'EnKS. Les covariances d'erreurs chimiques- dynamiques sont essentielles à la réduction de l'erreur de vents dans l'état analysé du modèle, en particulier les covariances ozone-vent qui font effet dans la haute troposphère et basse stratosphère. Des expériences additionelles avec un état initial fortement biaisé, en l'occurence un réchauffement stratosphérique soudain, confirment l'abilité de l'EnKF à transférer de façon efficace l'information depuis les observations d'ozone vers l'état dynamique du modèle.

Full textPhonological assimilation may change the acoustic shape of words according to the influence of surrounding segments. Word recognition has to cope with this systematic variability which characterizes spoken language. Three word-detection experiments in French, English and American English show that listeners use implicit phonological knowledge of the assimilation processes that exist in their language. Moreover, this knowledge of the assimilation independently of the activation of a lexical form, as the same compensation patterns have been observed in words and in non-words. This compensation mechanism shows some flexibility : comparing French and American second language (L2) learners shows that beginners use the phonological system of their native language to compensate for assimilation processes that exist in L2, but that more advanced learners develop a specific system dedicated to L2 within a few years of exposure

Full textUnderstanding and forecasting the evolution of geophysical fluids is a major scientific and societal challenge. A good forecast must take into account all available information on the studied system. These informations include models, observations and a priori knowledge. Data assimilation techniques combine all these informations in a consistent way to produce model inputs. During the last decades, many satellites were launched to increase the knowledge of earth. They produce, among others, image sequences showing the dynamical evolution of geophysical processes such as depressions and fronts. These images sequences are currently under-utilized in data assimilation. This thesis presents a consistent approach for taking into account image sequences in variational data assimilation. After a presentation of images, their current use and its limitation, we introduce the concepts of interpretation level, image space and image operator used for direct image sequences assimilation. We also propose a new approach of regularization based on generalized diffusion for ill-posed inverse problems. Preliminary results on image processing and image sequences assimilation show a promising approach that solve most of the problems encountered with classical approaches of regularization

Full textThis paper addresses the expectation that immigrants will assimilate into the culture of their new country, why that expectation may be legitimate and how the modern state may act upon it. The central contention made is that because a national culture provides meaning and structure to the lives of members, and because that culture must be both traditional and institutionalized by the state to fulfill that purpose, if the state’s institutions, processes and procedures through their association with the national culture create an assimilative pressure on immigrants, this is morally permissible. However, the modern state is restricted from actively pursuing assimilation in the private sphere because of its commitment to individual liberty. Implications of this argument for the nature of citizenship and public policy are also discussed.
