Balancing of multi-stage pump using the coupling hub
2019
In this paper, we present an investigation to perform a temporary on-site balancing of machines which rotor is not accessible, such as multi-stage oil centrifugal pumps, in order to bring back the vibration magnitude below the alarm threshold, waiting for the scheduled general review of the machine. We have shown that if the vibration measured on the Driver End Support (DE) is very higher than that measured on the Non Driver End Support (NDE), we can consider the Coupling Hub fitted to the Pump (CHP) a correction plane in order to apply on site balancing by means of the Influence Coefficients Method. This permits to overcome the problem of the inaccessibility of the rotor and to solve, in t…
Does social climate influence positive eWOM? A study of heavy-users of online communities.
2018
Abstract This paper provides a deeper understanding of the role of social influences on positive eWOM behaviour (PeWOM) of heavy-users of online communities. Drawing on Social Interaction Utility Framework, Group Marketing and Social Learning Theories, we develop and test a research model integrating the interactions between the social climate of a website and Interpersonal Influences in PeWOM. 262 Spanish heavy-users of online communities were selected and the data analysed using partial least squares equation modelling. Overall, the model explains 59% of the variance of PeWOM on online communities. Findings reveal that interaction with other members of the online community (Social Presenc…
Latviešu influenceru priekšstati par atbildību auditorijas priekšā, publicējot apmaksātu saturu sociālajā tīklā YouTube
2019
Bakalaura darba “Latviešu influenceru priekšstati par atbildību auditorijas priekšā, publicējot apmaksātu saturu sociālajā tīklā YouTube” galvenais mērķis ir noskaidrot latviešu YouTube influenceru izpratni par atbildību publicējot apmaksātu saturu un cik ļoti tas atbilst novērojumiem viņu YouTube kanālos. Darba teorētisko daļu veido trīs nodaļas – sociālie mediji, reklāma internetā un medijpratība. Darba empīriskajā daļā izmantota kontentanalīze, lai analizētu četru YouTube kanālu saturu 2019. gada februāra – marta griezumā. Pēc tam izmantotas daļēji strukturētās intervijas, lai intervētu blogu autorus. No pētījuma rezultātiem izriet vairāki secinājumi, kas parāda to, ka influenceri lielu …
"Youtube" un "Instagram" influenceri par minimālismu: komunikācija un loma attieksmes, paradumu un uzvedības maiņā
2021
Bakalaura darba “Youtube” un “Instagram” influenceri par minimālismu: komunikācija un loma attieksmes, paradumu un uzvedības maiņā mērķis ir izvērtēt, vai influenceri, komunicējot caur sociālajiem medijiem, spēj ietekmēt savu sekotāju dzīves stila paradumus, pievēršot auditorijas uzmanību minimālismam. Darba teorētisko daļu veido nodaļas par sociālajiem medijiem un to veidiem, minimālismu, influenceriem, kā arī pētīta lietojuma un apmierinājuma teorija. Pētījumā analizēts latviešu influenceru Edgars Feščenko un Lauras Arnicānes radītais saturs “Youtube” un “Instagram” plaformās, izmantojot kvalitatīvo kontentanalīzi. Darba ietvaros tiek veikta interneta aptauja un daļēji strukturētas interv…
Contribution à l'estimation non paramétrique des quantiles géométriques et à l'analyse des données fonctionnelles
2008
In this dissertation we study the nonparametric geometric quantile estimation, conditional geometric quantiles estimation and functional data analysis. First, we are interested to the definition of geometric quantiles. Different simulations show that Transformation-Retransformation technique should be used to estimate geometric quantiles when the distribution is not spheric. A real study shows that, data are better modelized by geometric quantiles than by marginal one's, especially when variables that make up the random vector are correlated. Then we estimate geometric quantiles when data are obtained by survey sampling techniques. First, we propose an unbaised estimator, then using lineari…
Measurement of the intergranular corrosion growth kinetics on a 2024 aluminium alloy : new experimental approaches of damage as function of the envir…
2017
Costs of aeronautical maintenance can be reduced by implementation of “smart” inspection strategies integrating predictive data on the evolution of defects such as the propagation rate of intergranular corrosion.In this work, intergranular corrosion damage on 2024 aluminium alloy was characterized by two modes : the “perforating” damage (dissolution of the grain boundary tips) and the “blunting” damage (dissolution of the grain walls in the intergranular cavities). To evaluate the “perforating” damage, a new version of the TFP method (OTFP method) which is more complete, was designed. The OTFP method allows to detect all the intergranular corrosion defects and not only the fastest full pene…

Conscious and nonconscious influences in the sensory domain
2013
Présentation (résumé 1 p.) ; http://www.pangborn2013.com/; International audience; Characterizing the relationships between conscious and unconscious processing is one of the most important goals of cognitive psychology. Renewed interest in the nature of consciousness has reignited long-standing debates about the reach of the unconscious -- the extent to which behaviour can be influenced by knowledge we are not aware of. According to Nisbett & Wilson (1977), subjects can be "(a) unaware of the existence of a stimulus that importantly influenced a response, (b) unaware of the existence of the response, and (c) unaware that the stimulus has affected the response." Many studies have now (argua…
Electronic implementation of a non-linear oscillator subjected to noise : application to the modeling of neuronal information coding
2011
We study the nonlinear FitzHugh-Nagumo model witch describes the dynamics of excitable neural element. It is well known that this system exhibits three different possible responses. Indeed, the system can be mono-stable, oscillatory or bistable. In the oscillatory regime, the system periodically responds by generating action potential. By contrast, in the mono-stable state the system response remains constant after a transient. Under certain conditions, the system can undergo a bifurcation between the stable and the oscillatory regime via the so called Andronov-Hopf bifurcation. In this Phd thesis, we consider the FitzHugh-Nagumo model in the stable state, that is set near the Andronov-Hopf…
