Device uses waves to “print” on water surface

Now, I just stumbled upon this some time back. Very interesting to say the least..

Researchers at Akishima Laboratories (Mitsui Zosen), working in conjunction with professor Shigeru Naito of Osaka University, have developed a device that uses waves to draw text and pictures on the surface of water.



The device, called AMOEBA (Advanced Multiple Organized Experimental Basin), consists of 50 water wave generators encircling a cylindrical tank 1.6 meters in diameter and 30 cm deep (about the size of a backyard kiddie pool). The wave generators move up and down in controlled motions to simultaneously produce a number of cylindrical waves that act as pixels. The pixels, which measure 10 cm in diameter and 4 cm in height, are combined to form lines and shapes. AMOEBA is capable of spelling out the entire roman alphabet, as well as some simple kanji characters. Each letter or picture remains on the water surface only for a moment, but they can be produced in succession on the surface every 3 seconds.

Researchers at Akishima Laboratories have developed similar devices in the past that used waves to draw pictures on the surface of water, but those devices had trouble producing letters with straight lines (such as the letter K). Additionally, it took the previous devices up to 15 minutes of data input time to produce each letter.

The newly developed technology uses improved calculation methods for controlling the wave generators, relying on formulas known as Bessel functions. In addition to being able to draw letters consisting of straight lines, the input time has been drastically reduced to between 15 and 30 seconds for each letter.

Akishima Laboratories expects the technology to be incorporated into amusement devices that combine acoustics, lighting and fountain technology, which they hope to see installed at theme parks and hotels.

Now, hvnt we studied Bessel functions sometimetime in coll?? Under Jhakkas(JKS) maybe :D ??

A place called home...

Driving back from college some days ago, lost amidst the songs playing on the stereo, a sudden sight arrested my attention. I have no idea why it did, I guess it wouldn't have on any other day.

A small house, with a light on in one of the rooms. A woman standing in the balcony chatting with (I guess) a neighbor, and two kids playing in the small park right underneath. I suppose it just reminded me of my childhood, of maybe about 10-12 years ago. We also used to live in a small(er) apartment near JLN stadium. Lots of friends (read children of the same age group), and a couple of rather special ones as well. I still remember the way we kids used to rush off to the stadium grounds every evening in the summer months, buy our customary lick-lolly from our old ice-cream waale uncle. Then rush off into the fields and just roll down the slopes, play hide-and-seek, chain-chain and u know, basically have the time of our lives. Our mothers standing in the balcony just like that woman, chatting with the friendly neighbors talking about all and sundry. Dad coming home in the evening in the rain, with my sis worried ki the car would get wet (she was arnd 3-4 and sooooooooo cute..!!).

Ohhh, how i wish those days would return. Those uncomplicated days. No mad rush, with the life so peaceful. And john, irrespective of whatever u might think, i really do wish that we were born some 50 years ago or so... Just think of it. In the hills of Darjeeling, romancing with the love of ur life, meeting in the evenings in the cloud-covered dales. Peace all around, no tension of getting home early to be able to mail back some stuff to ur boss/colleague/professor. Just being able to spend some real quality time with the people u like.

I digress. So as I was saying, this sight really did move me. I was forced to pull over and stop. Another thing that shook me was how a small piece of land could so easily turn into such a special place. A place called home. Do you also get the amazing satisfaction/enigmatic feeling , when u return home after a trip, even if you had been out with your entire family..?? Is this home-sickness as well?? Or house-sickness?? I don't know.


But, such things do put everything else in perspective. That night, at danny's place, when we were all talking about our regrets/satisfying moments/learnings from our 4 years of college, I did mention something about not taking the ones close to you for granted, especially your family. I don't know as to how many of you actually paid attention to what I said. But I say it again yaar. There's nothing like home, nothing like family. I guess nothing, and nobody in this whole wide world is worth neglecting your family for. Not even the special 'one'. But obviously that is not to say that you forget your friends, which brings me to my last point.

We all are going our own diff ways now. John and maddy off to meet uncle sam. Danny would most probably do so too in a couple of years. Deepak off to bangalore, (i guess for quite a long time..). So just Gauri and me here.. We will all be making new friends. But please please let's not forget each other as well. I have the ugly tendency to indulge a bit to much in/with anything new that I get/find. But not this time, not with friends. So, milate rehana yaar. Please. I am extremely lucky to have so many great friends at one go. Now I don't want to lose all of them at one go as well.

So, here's to us, the geeky gang..!!! :D

Goodbye

by Rosebud

Well maybe now I should just say goodbye You used to be my friend But I never felt I really was yours So maybe this is the end. I'm different from you, all of you Each other we've never understood I hope that if I do tell you goodbye That it won't be for good. Whenever I'm mad it hurts me so bad And you don't even care I don't know why, I just want to cry And someday I won't be there. The streaks on my arm they've done me no harm They're only made of pen But once they are blood that turns brown like mud They'll be there again and again. If I'm mad at you I'll hurt myself too But that doesn't really matter Although when I hurt I feel like dirt And my spirit's bruised and battered. I do not know why it has to be so I really wish it did not But the way this has been going it is basically shot. You don't need me and we don't need we And that's how I think I know why These words are the ones I have to speak- I love you, but goodbye.

Here are some really nice poems i came across...

Am I Alone?
by Megan Hance
I get a funny feeling,
it comes from deep inside.
I get all mad and angry,
wanting to go and hide.

My doctor calls it depression,
my dad says it's just me.
But the thoughts and feelings,
no one will ever be able to see.

Some say I'm psycho,
some say I'm just weird.
It's like I'm a different person,
and the old me just disappeared.

I get really edgy,
I want to commit suicide real bad.
Then I get a headache,
followed by feeling sad.

I wish I could get help,
I wish it would go away.
Maybe if I keep praying real hard,
it will some day.
