Car servicing is a must do for every car owner, just like taking care of your wife, its a man job to pamper them well. Today I went for a service maintenance for my precious car at Puchong.

I must praise their speed in their deliverable as they never make me waited for more than 2 hours as of the my 3 maintenance service so far.  At first this makes me feel uncomfortable as my previous time with Nissan the minimum waiting time is at least 3 hours. And look how clean is their outlet, no single visible litter.

For a car owner of 3 brands of car to date, I am not really happy with how Honda treat their waiting customer at their service center. The facilities provided for customer entertainment is the worse than our local brand P2. This is not the first Honda service center, I changed to this center due to boring environment at the previous center. At least this outlet provided me a bigger TV (picture below). However, bad placement of the TV leaving the customers staring at the black screen.

Let’s see what’s more in the outlet. I found one small fun house for the kids which I was not interested. As usual, they had their hot drink machine place beside their fun house.

I dreamt in another parallel world (which is in my brain), the scientist has discovered that human being actually evolved during some major catastrophe events like earthquake. Their eyes pupil has different construction compare to the human that has not been through the event. The evolution enables them to act more logically and not fear during earthquake. This evolution does really reduce casualties during disasters as the human get out of chaos in order and fight to survive without panicking.

Fortunately, the scientists in my parallel world has another new technology to morph the DNA. By taking some strain of the DNA of earthquake survivors, they are able to produce vaccine to induce evolution for the normal human. At the end, everyone will be able to have this abilities by injecting the strain of DNA.

So I am curious, nowadays can we do that in our world?

HAHAHAHA end of story telling.

Father and sons moment. Dummies guide to Rempit

Hitman or not.. this baldie keep Oldtown in tact. I enjoy sipping my the tarik while he was busy with his n97.

P/s I hate my phone camera

RM10 only.. Lai lai… Sedap sedap..

CR,
Happy Birthday, I love you
Ken.

Anyone know CR / Ken, please comment here! I would like to meet this couple!

Idea

The idea behind compressed sensing is from the fact that the sparsity of useful information during data collection or sensing. From the data sparsity, a mathematical calculation can be used to calculate and reconstruct the data into useful information from the linear form of data sparsity.

Let me put them in layman view. Say you have a digital camera to capture images. The digital camera obtain the data from its sensor in RAW format (which means every bit of light is capture without any compression) and then only compressed to JPEG (conversion technique that convert RAW to a smaller size of image) to be stored into your storage. Typically, the size of a 10 megapixels RAW image is around 10+MB. On the other hand, the JPEG image of its equivalent is about 1/5 of its uncompressed brother. In this scenario, we actually wanted the 4MB information but we are capturing them at 10MB. The 6MB wastage of data includes noise, redundant data…

Hence, compressed sensing is about sensing them in compressed form right from the start and using high order mathematical formula to reconstruct them to the information we wanted. Theoretically, the performance of compressed sensing can be as good as reconstruct a data of only 10% of its original counterpart and reconstruct them back to full scale 100% original signal. Impressive isn’t it? This might not be far away, they will be with us in 5 to 10 years.

Benefits

From the above scenario, one might see there is a huge potential in this compressed sensing. They will elevate the technology in a new level for various specialties.

Medical

In medical industry, I can foresee compressed sensing will bring cheaper medical equipment and more detail medical report. Imaging device like MRI, Ultrasound, PET Scan… is very expensive. The price is heavy for a citizen of third world country to enjoy better medical diagnose and cure. With compressed sensing, the device can be scale down to 10 percent of the current sensor size, hence greatly reduce the price. To obtain the relevant information, we apply the formula to reconstruct it back.

Telecommunication

Signal processing in telecommunication can benefit a lot from this technology as well. In such that, we will have cheaper communication tower, better signal quality and even further communication into outer galaxy. Some of the new wireless device such as WiMAX suffer from bad signal quality due to obstruction by building and so on. GPS still does not work good within confined area. With compressed sensing, we might picked up very little data overtime in linear form but we can reconstruct them back to the form we wanted.

Financial

In financial market, we might see a better accuracy prediction in this more volatile market of our new age. With better prediction, our market will be calmer in the future which might help the poorer country to stay competitive against the giant. Let say, you want to predict the commodities in the near future. With current technology, there are too many variable to consider for a good prediction. One might exhaust too many resources just to get a slight prediction. With compressed sensing, our goal of information is to know whether the commodities will be increase or decrease hence we just need to reconstruct the data back from the known source. Now we might need data from various form like 100 years of historical data, countries political stability, GDP… But in the future we might just need the historical data and we get what we want.

Others

• Oil and gas industry can obtain better data for oil field (our oil price might not be that high anymore).
• Emotion prediction?
• Accurate survey
• Better storage
