In this paper we propose CUDA-based implementations of two 3D point sets registration algorithms: Soft assign and EM-ICP. Both algorithms are known for being time demanding, even on modern multi-core CPUs. Our GPUbased implementations vastly outperform CPU ones. For instance, our CUDA EM-ICP aligns 5000 points in less than 7 seconds on a GeForce 8800GT, while the same implementation in OpenMP on an...
Polycrystalline Bi-substituted iron garnet films with Cu added were prepared on glass substrate by rf diode sputtering followed by annealing. The addition of 3.4 at% Cu was effective both for decreasing the size of crystallites to about 1 ??m, and for increasing the coercivity to 5.4 kOe. The shape of statically recorded bits was also improved.
