Curves on the shape sphere

Results in Mathematics, 2003
The extended plane \(\mathbb{C}\cup\{\infty\}\) is considered as a 2-dimensional angle shape space associated to the Euclidean plane [\textit{J. A. Lester}, 52, No. 1--2, 30--54 (1996; Zbl 0860.51009) and Aequationes Math. 52, No. 3, 215--245 (1996; Zbl 0860.51010)].

FPGA Investigation of Enumerative Sphere Shaping for Probabilistically Shaped 64QAM

Conference on Lasers and Electro-Optics, 2022
We investigate the implementation of enumerative sphere shaping (ESS) algorithm in real-time PS-64QAM system for the first time. Experiments achieved 0.08dB/0.02dB SNR gain under strong/weak shaping situation with much larger power consumption compared with HiDM.

The shape of a moving sphere

Physics Education, 1995
Two computer programs (OBJETIVA and APARENTE) that show the difference between measuring and seeing an object in relativistic movement have been developed. Some results are shown here.

Shaping the Transnational Sphere

2014
In the second half of the nineteenth century a new kind of social and cultural actor came to the fore: the expert. During this period complex processes of modernization, industrialization, urbanization, and nation-building gained pace, particularly in Western Europe and North America. These processes created new forms of specialized expertise that grew
