Synthesis of 4-D beampatterns using 4-D arrays

2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016
This paper proposes three schemes for three scenarios to realize 4-D beampatterns. The synthesis of the unconventional arrays is based on the time-modulated optimized frequency offset. The retrodirectivity and harmonics are also used for multi-targets. Simulated results validate the proposed ideas.

Actions representation in a 4-D space

International Journal of Man-Machine Studies, 1991
In this paper a frame-based model is presented for the representation of actions in four dimensions (space+time). This model, called Action Net, allows the composition of different actions descriptions and the representations at different levels of detail: an action is represented by a tree of frames which degenerates in a single frame at the lowest ...

4-D broadcasting with MPEG-V

2010 IEEE International Workshop on Multimedia Signal Processing, 2010
Advances in media technologies brought 3-D TV home and 4-D movies to your neighbour. We present a framework for 4-D broadcasting to bring 4-D entertainment home based on MPEG-V standard. A complete framework for 4-D entertainment from authoring of sensory effects to environment description and commanding rendering devices for the sensory effects can ...

A 4-D approach for amelioration of periodontitis

Medical Hypotheses, 2019
Global prevalence of the severe periodontitis is at the alarming stage and its association with the systemic complications is highly evident which cannot be neglected. An insight into the pathophysiology of the periodontitis reveals that the promising amelioration could only be envisaged with the 4-D/multi-pronged approach of combining antibiotic along

4-D display of meteorological data

Proceedings of the 1986 workshop on Interactive 3D graphics - SI3D '86, 1987
The Man-computer Interactive Data Access System (McIDAS) developed at the University of Wisconsin-Madison Space Science and Engineering Center (UW-SSEC) collects large quantities of meteorological data in real time for storage, analysis and display on multi-frame video terminals.
