Complexity Mobile Networking

-

If we allow full mobile ad-hoc networking without any coordination, the interference among different mobiles will be serious. Then, almost nobody can communicate with any other terminals. The current wireless communication systems are coordinated by the centralized access pointer to avoid interuser signal interference. The access pointer makes the signals transmitted by the different mobiles orthogonal to each other so as not to generate interuser interference. We predict that the future mobile neetworking systems will not have a heavy network coordinator. When there is no coordinator, one possible solution to avoid the interference is to use beamforming arrays at terminals where beamforming can effectively suppress transmit and receive interference. For accurate beamforming with high perforamnce interference suppressing requires many antennas which are not practical in real situation because many antennas increase the installation cost such as RF price and device size limitation.

Missing Lester Young~~

-
I am a sort of Jazz fan. So to speak, I am interested in traditional Jazz played earlier than 'Bitches Brew' of Miles David. My favorate is Lester young who was called as 'Prez'(derives from president of Jazz) in 1930s through 1950s. Days ago, I stopped by a CD shop to buy one of his masterpieces. However, He seemed to be so old-fashioned that his booth disapeared. People don't know how beautiful classical Jazz is! His blowing is romantic and elegant so as to captivate us. I compared his playing with Coleman Hawkins who was the most popular saxophonist in 1930s, at the same time, remained the legend even now. Lester young's tone is relaxed, cool and quitely soft while Coleman hawkins is full of being masculine and powerful in his atmosphere. On listening Young's playing, I was fascinated with his music. His album changed my fixed idea over timber of tenor saxophone. It sounded a poem or an ode. I could imagine that I was under the sunny side when I listened

Jeff Koons and Ciciolina as Kitsch artists

-
Do you know about Jeff Koons? He is famous for showing 'Kitsch art' to the viewer since 1990s. These days, his works are paid attention by collectors and critics over the world. In spite of some of his works being really dirty and filthy, Jeff Koons is considered as reliable artist in art price or quality among living contemporary artists. Today, I want to say a serial photos called 'Made in heaven' which is acknowledged as, in fact, pornography. I wonder whether or not this set of photos belongs to fine art like Mattew Barney who are dealing with similar themes. Because these series are surprisingly so obscene and nasty that we doubt our eyes in front of them how and why he took pictures. These photos would be displayed or shown under the note saying 'Adults Only' even in galleries or auctions. Two models are an artist himself and his ex-wife Cicciolina who was a porno star and Italian congress member. I will show their works below. Fantastic! Now they divorced

I use Google blog sometimes. I don't know why I use it since I can not have many visitors for this blog site. Is there anybody who use this Google blog as well? Please give me your opinion about this blog. I also use another international version of blog, which is word-press.I guess there are many people who already use word-press regularly. 참조: Green Technology by New Science ( Google 사이드위키에서 보기 )
