Calculating geometric properties of three-dimensional objects from the spherical harmonic representation
The volume, location of the centroid, and second order moments of a threedimensional star-shaped object are determined in terms of the spherical harmonic coefficients of its bound...

Log-likelihood ratio clipping in MIMO-BICM systems: Information geometric analysis and impact on system capacity
The clipping of log-likelihood ratios (LLRs) in soft demodulators for multiple-input multiple-output (MIMO) systems with bitinterleaved coded modulation (BICM) was recently observ...

Modeling and Visualization of Cardiovascular Systems
Modeling complex organs, such as the human heart, requires a detailed understanding of the geometric and mechanical properties of that organ. Similarly, the model is only as accur...

How Reliable Are Practical Point-in-Polygon Strategies?
We experimentally study the reliability of geometric software for point location in simple polygons. As expected, the code we tested works very well for random query points. Howeve...

Random k-GD-Sat Model and its Phase Transition
Abstract: We present a new type of sat problem called the k-gd-sat, which generalizes k-sat and gd-sat. In k-gd-sat, clause lengths have geometric distribution, controlled by a pro...
