Three-dimensional

The research "A Robust Approach to Stereoscopic 3-D Video Watermarking Using Adaptive Hysteresis Noise Gate" aims to introduce an alternative approach to watermarking stereoscopic threedimensional (S3-D) video using a dual-tree complex wavelet transform (DT-CWT) with an adaptive hysteresis noise gate or NG-DCWT for short. The DT-CWT has demonstrated superior performance in video watermarking when compared with direct spatial watermark embedding techniques, as well as other traditional frequency-based approaches.

This solution does not require a high computational power. The methodology is a threedimensional map based approach, which uses the 3D map of the surrounding environment and data acquired by a tilting Laser Range Finder (LRF), to pinpoint the robot pose. Experimental results about the accuracy of the proposed method are presented in this paper.

a-Sarcin, a cyclizing ribonuclease secreted by the mould Aspergillus giganteus, is one of the best characterized members of a family of fungal ribotoxins. This protein induces apoptosis in tumour cells due to its highly specific activity on ribosomes. Fungal ribotoxins display a threedimensional protein fold similar to those of a larger group of microbial noncytotoxic RNases, represented by RNases T1 and U2.

The Soma Cube was invented in 1936 by Piet Hein, a Danish poet and puzzle inventor. It represents all possibilities of combining three or four cubes in a ‘notstraight’ way. Its seven pieces can be assembled to form thousands of figures; it is a kind of threedimensional Tangram in this aspect. A first origami version of the Soma Cube was introduced by Steve Biddle in his book ‘The New Origami’. Steve Biddle uses Sonobé units to produce the pieces and arrives at the impressive number of 120 units. Maarten van Gelder has developed a Soma Cube whose pieces are...
