YEAHHH

I done ... yess .. master saya officially dah abis with my last poster presentation .. yahuuuuuu

endless thot

hahahahaha .. i'm doing something impossible... my sv shud award me with dr if i able to make it possible.. :)

Dear xxx,
Many direct detect microwave radiometers have been successfully built. The xxx and xxx spaceborne radiometers, both of which I am involved with, use them. Many other ground based sensors do, too. It isn't possible to build one without a significant amount of amplification before the detector. This is because the natural thermal emission signal is too weak for the detector without it. In Dicke's case, the amplification was made after a frequency downconversion for the same fundamental reason - his signal was also too weak. Direct detection at W-Band will be very difficult because low noise amplifiers at that frequency are rare and expensive and because higher power gain stages at that frequency (needed after the low noise amplifier) are also problematic. If you need to build a W-Band radiometer, it will be much more economical to do so using frequency downconversion. To decide how much amplification you will need, look at the Tangential Signal Sensitivity (Tss) value of your detector. You will need the signal to be detected at least 10 times bigger (in power) than Tss so you can reliably measure it.
Good luck,
xx

A genius ...

Interesting haa...

analogue vs digital

uhuhh .. saya rasa sengsara ngn project sendiri. lagi sebulan and my lecturer cakap saya dah salah concept. I'm measuring a noise but I'm treating that noise as a noise .. uhh sound noisy?? yang sungguh sedih .. supervisor saya sgt busy and tak tau sgt pasal noise noise ni .. so dia takleh nak guide btul2 dia cuma boleh memberikan buku2 utk dibaca dan saya akan tertido setiap kali baca buku . boleh kah project saya ni completed?? .. uhh uhh .. agak susah bile dipikir2.. baik saya meredakan hati dengan bershopping.
someone told me before " I guess u're not analogue person" ... uhhhh .. i try to prove he wrong but i guess he right.

saya nak mandi ..!!!

~ i choose a dead end .. i have to make my own path...not my own grave!!

a rainy day

Lepas baca post pojan tadi tergerak lak nak post something related to what she wrote in The Sweetest Thing. Yeahh .. life is so sweetttt .. tapi banyak benda yg sweet happened kita tak perasan especially kalu those things done by our closest family and friends. Sometimes kita rasa apa yang diorng buat was obligation for being the 'closest' .. tapi sebenonye .. its their choice not they have to do. And sometimes maybe the way kita define "sweet" tu influence how we appreciate those thing. Like my case .. saya sungguh senang terpengaruh dengan movie .. huhuuhuhuh so kekadang terexpect cam dlm cete2 lak .. tapi rasanya .. anything done such that to make our life easy, happy.. n apa yang bagus la shud consider as "sweet". Kalau cam gitu there were too many things to list out so saya sangat malas .. but seriously thanks to everyone for those sweet-sweet things .. tapi nape ekk .. bile someone yang kita baru kenal done something good to us .. terus rasa sweet. sungguh confius la.

btw .. laptop saya dah baik after 2 weeks deman sebab hard disk problem. saya sangat suke hati..

Bercanda di pasiran pantai .. huhuhuuh

Baru je abis berconference ngn bdak2 busuk tu pasal plan utk next week. Initial plan nak gi Alton tower telah dirombak menjadi activiti shopping dan berbikini.. hehheheheheh... mcm sungguh lain dari tujuan asal. Anyway carboot still dalam top list sampai ada la manusia yang tak sedar diri nak gi sampai 2 carboot .. geleng kepala makcik. Looking forward to Bournemouth.. Lamanye tak bersantai kat pantai .. i miss my family :(

why?? i still dun know

How did you feel kalau ada org suruh bukak baju di khalayak ramai?? Its happened to me though bukan la kene bukak baju .. but I was asked to bukak my tudung mase security checking kat Paris De Nord. Naiza was in front of me tapi mase dia kene check tak perasan la plak sebab mase tu tgh sibuk letak bag kat conveyor. Then before I step thru the security pintu tu ... this one lady ni ask me to take off my camera and my tudung while pointed to it. At first .. I'm a bit blur .. i ask her a few time and dia mengiya kan je... so i thought new regulation ke .. maybe diorng dah bertambah strict after London Blast. pastu teringat lak pasal france takleh pakai tudung gi sekolah.. SO dgn kebluran tahap maksima and agak malu gak, i took off my tudung tinggalkan serkop je. dah lalu pintu .. tade la apa2 bunyi .. but that lady called me back ask me to even take off my serkop... rasa terkesima kejap tapi malas nak pikir .. tanggalkan je la ... dlm mase tu rase malu though im not alim sangat tapi malu la .. macam kene bukak baju depan org .. then org suruh bukak 'anak2'... uhh .. and bertambah malu n sakit hati .. rupanya it's only me yang kena .. budak2 lain tak kena pun. so it means bukan la new regulation ke apa2 ke .. what did i do yang pompuan tu sanggup wat gitu??? bile dlm train tu .. pikir2 makin la bertambah malu n geram. Sampai la ni I still cannot think why she ask me to take off the tudung. We made few assumption which among other ..
1. maybe the way i wore tudung macam fesyen macam omputih ikat2 kepala .. tapi agak tak logik gak la rasenya budak lain pun pakai cam sama je.
2. my tudung agak berbonggol kat belakang .. so dia suspect i brought bomb kat dalam tudung .. uhhhh!! the most reasonable assumption kot...
3. i look like british muslim ... ( rase pelik .. but at least ada 2 org pernah tanya if im a bangladesh ... am I ??? )
4. She just did a random checking ... but come on la ..kalau btul2 security takkan nak random je.
5. but i like to think that she jeles with me .. coz im cuter than her ... hahahahahhaha....

what ever it is .. i don't think she had the right to ask me took off my tudung.. terasa agak racist. If she really want to perform her duty checking my tudung yang maybe boleh sembunyikan bomb .. at least she should do it in private.. bukan nye kat public. .. and rase sungguh menyesal for not stand up for what she's done to me...terasa agak hina gak la:(. uhhh .. the most unforgettable experience yang jadik penutup my Europe tour for this year...
