NEVER TOO LATE

Four things you can’t recover; the stone after the throw, the word after its said, the occasion after its missed, the time after it’s gone.

assalamualaikum w.bt 

im happy..this week is really memorable~ ><

My advisor , Dr.Azran was the one that deliver the talk.. 

BIOELECTRONIC ENGINEERING..

woa~~~~

i'm not trying to boast him but trust me, he's the one that worth to be respected! even while i'm doing this, my heart races coz he is so amazing to me !! i respect him so much!

oh my God!!! 

He's so kind-hearted, ive got souvenir from him when he went for japan for almost a week :) .. the kuih raya a.k.a duit raya haji..haha..dont get jealous kay..

the talk was held at MJIIT building level 4, around 60++ students were there. combination of two classes of SMJE..

got to seat front coz  i'm early,always early if im not mistaken.. 

:D

and can see and hear clearly during that day..most of my friends which has the same advisor with me,this is their first time with Dr.Azran. They shocked as ask me for confirmation.hahaha~

guys, im not kiddin..its really him!!!

ok.

i need to stop pondering him at here.

now, i will share what ive learnt about bioelectronics~~~

DEFINITION OF BIOELECTRONIC ENGINEERING

       
coined term for a field of research that works to establish a synergy between electronics and biology.



FRAMEWORK OF BIOELECTROIC

The emerging field of Bioelectronics seeks to exploit biology in conjunction with electronics in a wider context encompassing, for example, biological fuel cells, bionics and biomaterials for information processing, information storage, electronic components and actuators. A key aspect is the interface between biological materials and micro- and nano-electronics

                          

example of electronic circuit 

remember resistor color code? :)

Dr.Azran stressed the importance of all the components and everything..everything in this world is connected by each other by the way :)

Then, he explained a little bit bout IMPEDANCE (Z)

While Ohm's Law applies directly to resistors in DC or in AC circuits, the form of the current-voltage relationship in AC circuits in general is modified to the form:


where
 I and V = therms or "effective" values. 
 Z          = impedance.
 For a pure resistor, Z = R. Because the phase affects the impedance and because the contributions of capacitors and inductors differ in phase from resistive components by 90 degrees, a process like vector addition (phasors) is used to develop expressions for impedance. More general is the complex impedance method.

                            

SERIES AND PARALLEL CIRCUIT

                            

VOLTAGE DIVIDER

                                     

RC CIRCUIT(low-pass)

  

Passive electronic filter--> RC as low-pass filter

Product of RESISTANCE and CAPACITANCE (R x C) is the time constant which inversely proportional to the cutoff frequency :

                                                        
where
fc --> measured in hertz
time constant ---> seconds
R --> ohms
C--> farads

TRANSFER FUNCTION 

This is my first time hearing that word.Basically, from what id understand ---->

Transfer functions are commonly used in the analysis of systems such as single-input sigle-output filters, typically within the fields of signal processing, communication theory, and control theory.

The term is often used exclusively to refer to linear, time-invariant systems (LTI). Most real systems have non-linear input/output characteristics, but many systems, when operated within nominal parameters (not "over-driven") have behavior that is close enough to linear that LTI sytem theory is an acceptable representation of the input/output behavior.

In its simplest form for continuous-time input signal  and output , the transfer function  is the linear mapping of the Laplace transform of the input, , to the Laplace transform of the output :

or

In discrete-time systems, the function is similarly written as   and is often referred to as the pulse-transfer function.

    

this is the simple video which might help u and of course me to understand more bout TRANSFER FUNCTION :)

ACTIVE ELECTRONIC REALIZATION

Another type of electrical circuit is an active low-pass filter.
In the operational amplifier circuit shown in the figure, the cutoff frequency (in hertz) is defined as:

or equivalently (in radians per second):

The gain in the passband is −R2/R1, and the stopband drops off at −6 dB per octave (that is −20 dB per decade) as it is a first-order filter.

                                  

ESTIMATION METHOD

        

Doppler signal discriminator
(to measure blood velocity)

PROBE DESIGN & DOPPLER EFFECTS

       -------------->     

Relation between blood flow velocity (Vd) and doppler shift 
frequency (fo)

wow, already sunset... 
and too many ideas to put into 
=='
gonna restrain a little bit
hahaha~

BLOOD VELOCITY SPECTRA

smd :)

SIGNIFICANT DATA

BIT BOUT BIOLOGY

a eukaryotic cell

                                        

myth and mysteries of human dna.

till forever, i will never ever believe that we have almost the same trait as chimpanzi..but it differ on how people think i guess.. hmm  :(

HUMAN DNA (double strand)

singing to the outmost..haha

lets sing and study!!!!..

dna~da~dna~dna~

still in my own world..

kekeke~

if u dont understand for once,do watch it again.our capability of understanding is different.. 

:)

                              

dna double helix

 ----- time is running and i will not walking..haha
Bioelectronic is such a new field in Malaysia obviously but i believe with all the professional that ive met, Bioelectronic is always possible today onwards. Nothing is impossible if u believe u can :) and my icon in Bioelectronic is of course my own advisor, Dr.Azran..

oh ya,just remember.. poster!!!!!

                     

group assignment :)
im anticipating all my mates cooperation .. we must give our very best :)

please continue reading to entertainment segment and watch amazing videos ive prepared especially for my reader.. <3 <3 <3

SNSD comeback!!

even i'm SONE but i dont like this mv as i love PAPARAZZI mv..

it feels like there is something missing. 

it doesnt have enough flavor.. how do u think?

      

yeorobun,

this is BLOCK B!!

~nilili mambo~

MISS A..

wow!! dae bak!! 

this is what im looking for..

boys out there! WATCH OUT..

nanun namja obshi jal sara..

hahaha~

time for food, i love western food as much i love malay food. its just that i come from all rounded and mixed family and eat many types of food :D

how bout u try it home.. :)

easy and simple

even though, this video is out-of-date as most people will probably say but i love it till now.. 

:D

yeorobun!!
gwenchana?
are u statisfied ?
i hope u are..
>_<
i need to stop first,
dont forget to read my upcoming post :)

Shinya Yamanaka (山中 伸弥 Yamanaka Shin'ya?, born September 4, 1962) is a Japanese physician and researcher of adult stem cells. He serves as the director of Center for iPS Cell Research and Application and a professor at the Institute for Frontier Medical Sciences at Kyoto University; as a senior investigator at the UCSF-affiliated J. David Gladstone Institutes in San Francisco, California; and as a professor of anatomy atUniversity of California, San Francisco (UCSF). Yamanaka is also the current president of the International Society for Stem Cell Research (ISSCR).

He received the Wolf Prize in Medicine in 2011 with Rudolf Jaenisch;the Millennium Technology Prize in 2012 together with Linus Torvalds. In 2012 he along with John Gurdon were awarded the Nobel Prize for Physiology or Medicine for the discovery that mature cells can be converted to stem cells.

with that

thank you for reading

love you guys

<3 my family more

haha
