Development of stratospheric communication platforms (SCP) as backbone to terrestrial networks

Planning of UMTS Networks Containing Stratospheric Platforms

The International Telecommunications Union (ITU) has endorsed High Altitude Platforms (HAPs) as an alternative means of providing UMTS wireless services. The utilisation of HAPs (High Altitude Platforms) in the access part of the upcoming UMTS networks can provide great flexibility to UMTS from the viewpoint of service provisions and fast infrastructure installation. Moreover, they offer these ...

Using Stratospheric Platforms

R&D for wireless communication systems using aircraft called high altitude platform keeping at an altitude of about 20 km has been made progress as a national project in Japan since 1998. In order to realize such novel wireless communication systems, allocation and maintenance of available frequency bands are the key issues. At this stage, following three frequency bands are allocated for the c...

Causal networks as the backbone for temporal data-to-text

Causal networks have been successfully used to explain the process of narrative comprehension in humans (Trabasso et al., 1989). This motivated their use in the automatic creation of fairy tales (Swartjes and Theune, 2006; Theune et al., 2007). Some have suggested that causal relations also play an important role in improving narrative generation from real-life temporal data (Hunter et al., 201...

Design of Optimal Topology of Satellite-Based Terrestrial Communication Networks

Topological design of terrestrial networks for communication via satellites is studied in the paper. Quantitative model of the network cost-analysis minimizing the total transmission and switching cost is described. Several algorithms solving combinatorial problem of the optimal topology design based on binary partitioning, a minimax parametric search and dynamic programming are developed by th...
