Friday.
Hello guys~~
Happy Friday..<3
Hurmm..okay.today I will tell you guys more about what I've learned in ElecSys class last Tuesday..^^..
Oh ya! before I forgot..for this week,, we've another new lecturer for this subject. His name is Dr. Azran Azham bin Noor Azmi..a handsome lecturer who just came back to Malaysia recently after staying for 15 years at Japan..=)
We were so impressed to learn with him. Of course he will teach us about electronics..
30th Oct,2012.
Tuesday.
Today..we have another class for Electronic System (ElecSys)..for this time..Dr Kamal had asked all of us to come (not separated into 2 groups like previous classes).. and go to Level 4 at MJIIT Building because we'll having lecture for this time.
As I arrived there..there are only couples friend of mine have come. The rests did not come yet. While waiting for them, I'm completing my math assignment..(sorry Dr.).. huhu..
Several minutes after that, our class starts when Mr Redzuan come with a person. At first, I thought that the guy is the person-in-charge for computer settings, but when Mr Redzuan said, " Okay, this is our new lecturer, Dr Azran. He gonna teach you about Bioelectronics." What?? okay, now I'm speechless..you know why?? because he looks so simple in appearance..haha..
Class starts as usual..Dr Azran gives a lecture about Introduction to Bioelectronics. Everybody seems to be very focus during the class because it is a new subject for us.
Based on my understanding, bioelectronic is the application of electronic in biology and medicine fields. Artificial pacemaker and limbs are amongst the application of bioelectronics..amazing, right??

Other than that, he gives us lecture about low-pass filter and high-pass filter, and also asked us to do some exercise related to this topic.
I'm not pretty sure about the functions both of it, thus I just Google on about them. Here it is:
A low-pass filter is an electronic filter that passes low-frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. It is sometimes called a high-cut filter, or treble cut filter when used in audio applications. A low-pass filter is the opposite of a high-pass filter.
A high-pass filter (HPF) is an electronic filter that passes high-frequency signals but attenuate (reduces the amplitude of) signals with frequencies lower than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. A high-pass filter is usually modeled as a linear time-invariant system. It is sometimes called a low-cut filter or bass-cut filter.High-pass filters have many uses, such as blocking DC from circuitry sensitive to non-zero average voltages or RF devices. They can also be used in conjunction with a low-pass filter to make a bandpass filter.
Later on, he teach us about Doppler signal discriminator which is used in bioelectronics and also the mysteries of human DNA..we feel overwhelmed knowing that the length of human DNA is 120 billion km which is equivalent to the distance from Earth-Sun for 400 times!! Wow!!

Hurmm,,maybe you're wondering..who's this guy?? Based on Dr Azran..this guy is one of the famous person in the bioelectronic fields. Recently in this year, he won the Nobel Prize for Physiology or Medicine along with John Gurdon for the discovery that mature cells can be converted to stem cells. Below is his bibliography..=)
Shinya Yamanaka born September 4, 1962. He 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-affiliatedJ.David Gladstone Institutes in San Francisco, California; and as a professor of anatomy at University 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 Millenium 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.
Before the class end..Dr Kamal tells us that we'll have a group project..that is making poster.. I've got title of Computer Control System..each group has 3 or 4 members. Mine has 4..2 boys and girls.. Everybody seems shocked when Dr Kamal said that we're going to present our work in front of other lecturers..OMG!! The dateline is 27th Nov..hopefully we can make and try our best..^_^..as the saying goes around : Practice makes perfect..
