Repeated Human Exposure to Semivolatile Organic Compounds by Inhalation: Novel Protocol for a Nonrandomized Study

Dominique Grandjean, Florian Frédéric Vincent Breider, Guillaume Suarez

Background: Semivolatile organic compounds (SVOCs) comprise several different chemical families used mainly as additives in many everyday products. SVOCs can be released into the air as aerosols and deposit on particulate matter during use by dispersion, e ...

Rotation, Scale and Translation invariant image retrieval method based on Circular Segmentation and Color Density

Pierre-André Farine, Sara Grassi Pauletti, Pradyumna Ayyalasomayajula

We propose a fast and efficient method for Content Based Image Retrieval (CBIR) which uses color densities within concentric circular zones of the image, encompassing edge-pixels. This method is invariant to Rotation, Scale and Translation (RST). Small-siz ...

Reverse-Engineering Drivers for Safety and Portability

George Candea, Vitaly Chipounov

Device drivers today lack two important properties: guaranteed safety and cross-platform portability. We present an approach to incrementally achieving these properties in drivers, without requiring any changes in the drivers or operating system kernels. W ...
