Hydrocarbon accumulation and resources evaluation: Recent advances and current challenges

Physical activity and exercise: recent advances and current challenges.

This article presents an overview of major developments in physical activity and exercise for health promotion and disease prevention during the past 10 years. The importance of physical activity to physical and mental health was increasingly recognized. Assessment methods appropriate for diverse population groups were developed, and understanding of correlates of regular physical activity impr...

3D Geometry Compression - Recent Advances and Challenges

Polyhedral models, which are used in most graphics applications, require considerable amounts of storage, even when they only approximate precise shapes with limited accuracy. To support internet access to 3D models of complex virtual environments or assemblies for electronic shopping, collaborative CAD, multi-player video games, scientific visualization, representations of 3D shapes must be co...

Arrangements in Geometry: Recent Advances and Challenges

We review recent progress in the study of arrangements in computational and combinatorial geometry, and discuss several open problems and areas for further research. In this talk I will survey several recent advances in the study of arrangements of curves and surfaces in the plane and in higher dimensions. This is one of the most basic structures in computational and combinatorial geometry. Arr...
