The Radar Antenna

I have nothing fancy to write today. Therefore, instead i am writing something that will make most of you fall asleep.

The Purpose of the radar is to act as a transducer between free-space propagation and guided-wave (transmission-line) propagation. The function of the antenna during transmission is to concentrate to the radiated energy into a shaped beam which points in the desired direction in space. On reception the antenna collects the energy contained in the echo signal and delivers in to the receiver. Thus the radar antenna is called upon to fulfill reciprocal but related roles.

Well, did i manage to make you sleepy? Now go to sleep!!

Time to Change

It is sickening everytime when i think about how i am being underpaid by my employer. the fact that there are less than 3 companies in Malaysia that can do what we can do today. still, we are paid just like any other IT company. heck! we are working with radar systems, electronic warfare and such. the cost of each of the equipment is mindboggling but the company treat us as if we are installing desktop computers and servers. It is not just about the amount of work that we give, but it is more about the expertise, knowledge and experience we have. this 3 elements can be easily exported to the competitor (by the means of hiring us with tripple pay!). Our bosses just dont realise this, until one day we would say "au revoir!" and they would say something like "oh, we just eat our own shit! the competitor can do what we always do!". just wait and see ... the pictures below say everything. ordinary company just don't do this. .n.g.

Is there a Theory of Everything? by Dr Michio Kaku

Image
i came across this article from Dr Michio Kaku, a reknown physicist. i've read a lot of journals, watched so many Discovery Channels and National Geographics programmes on the Theory of Everything, yet i still have not come across a good article to explain it all from A to Z. even wikipedia is not so convincing this time (wikipedia has been my favourite on other topics). i hope this blog eventually can shed some lights on this theory as i gather more articles and journals. for a start, let's read this article from Dr Michio Kaku. Dr. Michio Kaku, Professor of Theoretical Physics at the City University of New York, is the author of VISIONS: HOW SCIENCE WILL REVOLUTIONIZE THE 21ST CENTURY and the best-seller HYPERSPACE. [begin of article] When I was a child, I used to visit the Japanese Tea Garden in San Francisco. I would spend hours fascinated by the carp, who lived in a very shallow pond just inches beneath the lily pads, just beneath my fingers, totally o blivious to t...

Yellow

Colours give me different vibes. Today i choose YELLOW. First thing in my mind, yellow reminds me of DIGI Yellow Man. OK, i have to admit that they had successfully tagged yellow with their products into our mind. But digging further inside me, the song "Yellow" by Coldplay struck into me. I somehow rather clueless about the meaning of the lyrics. Nevertheless, i sang this song to my sons when they were babies. (oh they both had "yellow" @ jaundice). And what so meaningful yesterday, i could play the song again in my car .. thank goodness!! Feel like i've told this story to someone before ... DE JAVU !! hehe ... By the way, Chris Martin (of Coldplay) explained that he was inspired by Yellow Pages. I can understand why .. hehe. If you've been to Eiffel Tower, then you probably have seen the stairs above. Yellow, Lyrics and Song by Coldplay. Enjoy!! .n.g. Look at the stars, Look how they shine for you, And everything you do, Yeah, they were all...
