Currently in North America, biodiesel is mainly produced from vegetable oils such as soybean and canola using a homogenous catalyst, KOH or NaOH. Two associated challenges are: 1) using edible oils as feedstock may impact food and feed supply adversely; 2) a great amount of water is needed to wash off the homogeneous catalysts dissolved […]

Commonly used hot air drying results in non-uniform shrinkage due to significant thermal gradients, especially at the last stage of drying. In this project we will study two-stage drying of apple slices with hot air at beginning and microwave at the end to minimize effect of non-uniform heat transfer. The goal of the project is […]

3D indoor scenes are ubiquitously needed in the virtual world, e.g. 3D games, movies and virtual reality. These scenes provide the essential virtual environments for 3D characters to perform daily activities and tasks. Current scenes on public available datasets, e.g. Trimble 3D warehouse, are usually clean and well organized, and might not be sufficient to […]

Fresh water is becoming an increasingly precious resource, and correct management plans are vital to the continued survival of groundwater aquifers and rivers for human use. 2013/2014 was the driest year in São Paulo State, and this drought is still affecting agricultural land use. In parallel with the decreasing water supply, we have an increasing […]

Most studies on violence employed by criminal groups are based upon the idea that illegal business, much like legal companies, benefit from the stability, certainty, and freedom that can be found in peaceful locations. Because violence generates mistrust, makes trade more costly, and draws the attention of the police, it is usually assumed that criminals […]

La pollution des eaux par les produits pesticides présente un problème environnemental bien identifié par les pouvoirs publics. L’objectif général de ce projet est de développer un procédé électrolytique à l’échelle du laboratoire pour décontaminer des effluents agricoles contenant des pesticides. Pour ce faire, l’électro-oxydation est une application des propriétés électrochimiques pouvant être efficacement utilisée […]

The project focuses on the design and development of a wearable electric field sensor. Mathematical simulation, mechanical design, optical system built-up and signal processing will be involved. The project will be conducted in the Laboratory of Ultra High Precision Mechatronics at Beihang University (BUAA), Beijing. The student will need to analyze and simulate the relation […]

The indole subunit is a near-ubiquitous component of biologically active natural has become an important building block or intermediate in the synthesis of many pharmaceutical agents. Such as indole-3-carbinol, found in cruciferous vegetables has been shown to inhibit carcinogenesis. In this project I will focus on studying of action mechanism (cell apoptosis, angiogenesis inhibition and […]

Located in Mexico City, La Villa de Guadalupe is very important place for Mexicans and it is the shrine where the original painting of Virgin of Guadalupe is preserved. She appeared to a native Mexican, Juan Diego in 1531. Both, the sacred place and the Virgin are considered the most important icons for the Mexican […]

Sinkhole and ground surface collapse frequently occur in urban areas such as highway, roads or around buildings. Usually the failure process in rather sudden without much evidence or obvious signs. This catches people by surprise and results in accidents, injuries or even death in some cases. From current studies and case analysis, most of the […]

Au cours des dernières années, le Brésil a amélioré ses services d’assainissement et d’accès à l’eau à travers tout le pays toutefois plusieurs localités sont encore très en retard par rapport à ses services. Ces localités sont majoritairement les milieux défavorisés où de nombreuses personnes sont pauvres : ce sont les favelas. Ce retard a […]

The two last years, the emergence of car mobile applications (Uber for example) has disturbed the taxi industry. This new market is becoming more predominant and no solution has been found to reach an objective equilibrium with the older modes of transport. This problem is appearing all around the world with different companies depending on […]
