La couche la plus externe de l’atmosphère solaire, la couronne, est composée de plasma dont la température dépasse de plusieurs ordres de grandeur celle de la surface.Expliquer comment la couronne est chauffée à des températures de l’ordre d’un million de degrés constitue un défi majeur de la physique solaire.Dans ce contexte, je m’intéresse au cha...
Cluster analysis by k-means algorithm by R programming applied for the geological data analysis is the scope of the presented paper. The research object is the Mariana Trench, a hadal trench located in west Pacific Ocean. The study evaluates the similarity of the geological data by the analysis of their attributes. The original observation data set...
With the evolution of automation and artificial intelligence tools, mobile networks havebecome more and more machine reliant. Today, a large part of their management tasks runs inan autonomous way, without human intervention. In this thesis, we have focused on takingadvantage of the data analysis tools to automate the troubleshooting task and carry...

Plain English summarySome previous researchers (Locock et al) have written about what may be the best way for public contributors to be involved in data analysis in research projects. Their experience has been that giving public contributors large amounts of text to read is not the best use of their time and experience. They have recommended that a...

Time History of Events and Macroscale Interactions during Substorms (THEMIS) data are used to investigate the magnetic field structures in the vicinity of the magnetopause. Generally, the tendency that the farther away from the Earth, the weaker the detected magnetic field is expected inside the dayside magnetopause. Here we show two cases which co...
This paper introduces an application of R programming language for geostatistical data processing with a case study of the Mariana Trench, Pacific Ocean. The formation of the Mariana Trench, the deepest among all hadal oceanic depth trenches, is caused by complex and diverse geomorphic factors affecting its development. Mariana Trench crosses four ...

Data quality (DQ) is an important prerequisite for secondary use of electronic health record (EHR) data in clinical research, particularly with regards to progressing towards a learning health system, one of the MIRACUM consortium's goals. Following the successful integration of the i2b2 research data repository in MIRACUM, we present a standardize...

Integrating electric vehicles (EVs) into vehicle fleets deployed by transportation network companies (TNCs; e.g., Uber and Lyft) is a particularly promising way to realize the benefits of vehicle electrification, due to the greater average miles traveled and passenger occupancy of TNC fleets. In this report, the researcher examines EV use in TNC fl...
The METRANS Transportation Center is working with California Department of Transportation (Caltrans), the California Governor’s Office of Business and Economic Development, and the California Air Resources Board to implement the economic competitiveness provisions of the California Sustainable Freight Action Plan (CSFAP).The CSFAP aims to reduce gr...
