A case study on the influence of fuel quality on the concentration and chemical components of PM2.5 from vehicle emission

Recently, poor air quality due to fine particles (PM2.5) in large areas of China has gained much international attention, and vehicle emission is a significant source of PM2.5. Fuel quality is one of the influencing factors on vehicle emission. However, due to a large number of potential factors including fuel attributes, emission control devices, and […]

Data Mining of Urban Mobility Pattern Using Taxi Trajectory Data

Urban mobility results from human movements from one region to another for interaction such as working, trading goods and other social events. Urban mobility has caused not only urban prosperity, but also some problems in the urban system, such as congestion, air pollution, energy consumption, public health and disease transmission. Therefore, understanding urban mobility is […]

Computer Simulation of Geospatial Dynamics: How Do Cities Grow and Evolve?

Cities are the engines of creativity, wealth creation and economic growth in our society. Despite the increasing importance of cities in modern world, our ability to understand them scientifically and to manage them well in practice is limited. The greatest difficulties and challenges to any scientific approach to cities have resulted from their many interdependent […]

Modéliser les données multi-relationnelles comme des séquences / Modeling multi-relational data as sequences

The objective of the project is to automatically learn missing information in knowledge bases (KBs), which are becoming essential tools to deal with big data, since they provide means to organize, manage and retrieve all this knowledge. These databases are huge directed multi-relational graphs, whose nodes correspond to entities connected by edges representing a certain […]

The luminescence of cavitation bubble generated by spark discharge in water

Cavitation bubble can be generated by ultrasound, laser or spark discharge underwater. It has good potential in the application of medical treatment, environmental treatment and surface cleaning. When the bubble collapse, the vapor inside will be compressed quickly and the temperature will rise to several thousand Kelvin, even reach ten of thousand Kelvin, and the […]

Experimental and Computational Investigationson Catalytic Mechanism of Ethylene Polymerization over Ziegler-Natta Catalysts

Magnesium chloride (MgCI 2) is a commercial catalyst important for the production of polyolefin material. Although magnesium chloride has been used for over 50 years, the active site is still not entirely known. This research aims to learn more about the active site. The formation of defective magnesium chloride surfaces acts with Ziegler-Natta catalysts and […]
