A new method to "clean up" ultra high-frequency data

2007

In the applied econometrics, the availability of ultra high-frequency databases is having an important impact on the research market microstructure theory. The ultra high-frequency databases contain detailed reports of all the financial market activity information which is available. However, ultra high-frequency databases cannot be directly used. On one hand recording mistakes can be present, on the other hand missing information has to be inferred from the available data. In this paper, we propose a simple method in order to clean up the ultra high-frequency data from possible errors and we examine the method efficacy when we analyze data by using an autoregressive conditional duration (A…

Probabilités d’orientation déjouées… Des bacheliers professionnels en STAPS et classes préparatoires aux écoles d’Art

2016

Si les bacheliers professionnels font figure d'« outsiders sociaux et scolaires », avec des profils qui ne les placent pas dans une position avantageuse par rapport à la réussite dans les études supérieures longues, ils se révèlent comme des « ayants droit » du sport et de l'art, avec une orientation qui ne s’effectue pas « par défaut », mais au contraire selon une « logique vocationnelle » en premier lieu.

Probabilités d'orientation déjouées, par le sport ? Le cas des bacheliers professionnels

2021

National audience; Les bacheliers professionnels qui souhaitent continuer des études supérieures hors sections de technicien supérieur s'engagent dans un chemin escarpé où ils sont traditionnellement peu attendus. Quelques-uns s'inscrivent en licence de sciences et techniques des activités physiques et sportives (STAPS) ou en classe préparatoire aux grandes écoles (CPGE). Quels sont les profils de ces jeunes et comment justifient-ils ces choix qui peuvent paraître atypiques et risqués ? Plusieurs recherches récentes, axées sur la transition lycée enseignement supérieur, permettent d'appréhender les parcours de bacheliers professionnels dont les engagements extrascolaires peuvent influencer …

Juvelieristrādājumu veikala izveides projekts

2021

Maģistra darba “Juvelierizstrādājumu veikala izveides projekts” mērķis ir uzlabot juvelierizstrādājumu tirdzniecības piedāvājumu Latvijas tirgū. Problēmas identificēšanai autore veica pētījumu par juvelierizstrādājumu nozares situāciju, problēmām un iespējām. Maģistrā darbā ietvaros tiek risinātā konkrēta problēma par zemu patērētāju vajadzībām atbilstošu tiešsaistes juvelierizstrādājumu tirdzniecības piedāvājumu. Lai risinātu konkrētu problēmu, darba autore piedāvā izveidot tiešsaistes juvelierizstrādājumu veikalu. Maģistra darbs sastāv no 84 lapaspusēm un 34 pielikumiem, 11 tabulām un 19 attēliem.

Gendered Pathways Toward STEM Careers: The Incremental Roles of Work Value Profiles Above Academic Task Values.

2018

Drawing on Eccles’ expectancy-value model of achievement-related choices, we examined how work values predict individual and gender differences in sciences, technology, engineering, and math (STEM) participations in early adulthood (ages of 25/27, 6 or 8 years after postsecondary school), controlling for subjective task values attached to academic subjects in late adolescence (11th grade, age 18). The study examined 1,259 Finnish participants using a person-oriented approach. Results showed that: (a) we could identify four profile groups based on five core work values (society, family, monetary, career prospects, and working with people); (b) work-value profiles predicted young adults actua…

Efficient Dense Disparity Map Reconstruction using Sparse Measurements

2018

International audience; In this paper, we propose a new stereo matching algorithm able to reconstruct efficiently a dense disparity maps from few sparse disparity measurements. The algorithm is initialized by sampling the reference image using the Simple Linear Iterative Clustering (SLIC) superpixel method. Then, a sparse disparity map is generated only for the obtained boundary pixels. The reconstruction of the entire disparity map is obtained through the scanline propagation method. Outliers were effectively removed using an adaptive vertical median filter. Experimental results were conducted on the standard and the new Middlebury datasets show that the proposed method produces high-quali…

An approach to identify new antihypertensive agents using Thermolysin as model: In silico study based on QSARINS and docking

2019

Thermolysin is a bacterial proteolytic enzyme, considered by many authors as a pharmacological and biological model of other mammalian enzymes, with similar structural characteristics, such as angiotensin converting enzyme and neutral endopeptidase. Inhibitors of these enzymes are considered therapeutic targets for common diseases, such as hypertension and heart failure. In this report, a mathematical model of Multiple Linear Regression, for ordinary least squares, and genetic algorithm, for selection of variables, are developed and implemented in QSARINS software, with appropriate parameters for its fitting. The model is extensively validated according to OECD standards, so that its robust…
