True tree diagram for mind-map

-
Image
Tree diagram, or mind map, has been used for many areas including research, business, study. One of example programs to build tree diagrams is Freemind which is easy to use. While I use freemind, I suddenly felt that Freemind is needed to be upgrade with a new feature. Remind that tree diagrams in Freemind resembles not full structure but only a half part of a full tree. Recent half tree form mindmaps are convenient to show various divided facts effectively. However, it is not very effective to analyze facts and to tell a story about associated actions. Now, I propose the following new usage of tree based mind-map:

2008 is the 4F's year

-
I, James, predict that 2008 is the 4F year. 4 is the perfect number among all natural numbers. 4F consists of feeling, fiction, female and freeture-free future. 3F that consists of feeling, fiction, female has been mentioned by John Naisbitt , the author of 'Mind set', so that I added freeture since free based future wise thinking is the more important key word than ever.

Downlink Beamforming

-
In wireless communications, either more spectrum or higher spectral efficient communication technologies can increase the data rate, which enables to service various multimedia contents. Since frequency spectrum is a natural resource, it is inherently limited so that it costs very high. Therefore, it is very important to find highly spectral efficient communication technologies. However, new good technologies requires higher complexity in terms of development, installation and so on. Therefore, our research goal is either to optimize the current technology and to find a new innovative technology. Beamforming is a scheme to overcome the limitation of the spectrum resource. Beamforming is used for spatial division multiple access which increases the system throughput by spatially diving multiple user signals. Spatially diving let multiple users communicate simultaneously in a same frequency band. When beamforming is applied for the downlink transmission, we call it as downlink beamform...
