WSN & Robotics

Last year I stayed in UC Berkeley for a short-term study for four months, and the topic I focused on was the security issue on wireless sensor networks (WSNs). However, I used to major in Robotics which is a little bit different from WSNs. The common point between them is that there are lots of sensors inside the hardware. Therefore, some crazy idea comes into my mind and brings me a good start. Since I had studied on WSNs over a past half year, I start to think about how to combine the WSN with robotics. The ideas are as followed:

1. Location for the robot (such like wheel-robot) via WSNs
   
2. Robot network by applying WSNs
3. Applying both Robotics and WSNs on health care system
4. Fire alarm and rescue system by utilizing Robotics and WSNs
5. Secure issue between Robotics and WSNs
   

I believe that the topics stated above maybe have done by someone else, but there must be some point needed to be improved. It is a good time to start to survey the paper to check if there is anyone interesting about these researches right away. Let the game begins!!!

I am in Canada right now!!

I am in canada right now!
Actually, it is my first time to go abroad.
Also, it had been a long time for me to get here by plane.
It almost costs me 18 hours to get to Ottawa.
But it does not affect my happy mood.
The weather here is cool, just like the fall of Taiwan.

Wine in Laptop

Wine in laptop!! What a terrible thing it is. But in case someday this could happen to me, i need to prepare for it. Below is a link that teaches us how to deal with such condition. Keep it in mind, it makes things better.

1. You need to disconnect all power sources to not make things worse
2. Time is not your friend.

Useful Things to Know About Ph. D. Thesis Research

This article was written by H.T. Kung.(Prepared for "What is Research" Immigration Course, Computer Science Department, Carnegie Mellon University, 14 October 1987)

link:
http://www.eecs.harvard.edu/~htk/thesis.htm

There are several interesting topic in this article. In the subject 4 he presented 4 stages for a Ph.D student. And these stages are most important processes for student.

• Knowing everything stage
  • Student: "I have designed a supercomputer even before graduate school."
  • Faculty: speechless
• Totally beaten up stage
  • Student: speechless
  • Faculty: smiling at the student's progress so communication is possible now.
• Confidence buildup stage
  • Student: "I am not stupid after all." (student thinks)
  • Faculty: "Uh oh, she is ready to argue." (faculty think)
• Calling the shot stage
  • Faculty: "I am going to design an n-processor supercomputer."
  • Student: "You are crazy, because ..."

Maybe it is a good idea to translate it into Chinese some other day.

New Topic for WII

"An approach to improve the performance of WIImote via experimenting with WII sport under wireless sensor network."

Abstract

Recently my lab plan to buy a new equipment for some special purposes. The equipment is a video game console which is called WII made by Nintendo. For its new input device WIImote which contains several acceleration sensors and infrared detection, we design to purchase one. The WIImote is a new application of hybrid combination of acceleration sensors and infrared sensors, and it is also a kind of position system, since this concept is presented for a long time. But it is the first time we can see this kind of equipment in everyone`s home. Moreover, the WIImote connects to the console using Bluetooth under the wireless environment.So we bring up several new topic issues for WIImote in this project.

In order to deal with these issues, we devise several experimentations to improve the performance of WIImote. The experiment shows how we solve the problem we met during the training of WIImote. Furthermore, during the process of the experiment a new kind of algorithm was presented to point out the main problem we face. This is a new interesting topic, and we will keep on tracing it.

Opening of school

Today is the opening of my school, and i got this information yesterday. What a shake !! I thought that i still had a week of holiday left, but things were not so easy actually. So i went to school this morning unwillingly and started to execute the program that i charge with. My program is to improve the performance of a remote robot car by applying local lag or PHBDR. So i must find a way to measure the network delay between the client and the robot, and my boss give me a clue that maybe i can measure the delay via NTP protocol. Then it takes me a half day to finish a survey of NTP protocol used on Windows XP. Fortunately with the help of my parter, i find a program which conform to my need. I am so tired now and i need to take a break.
I find that my reading ability is getting a little bit improvement. Maybe it is the effect of the Modern Operating Systems which is a book written by Andrew s. Tanenbaum.

Write an article every three days

I found an interesting thing that till now i wrote an article every three days. Without any purpose, i just write down my feeling periodically and practice English writing ability every three days. It also means that i am just like an elementary school student who is involuntarily keeping diary everyday. But it is an old memory for me a long time ago. Actually every time when i decide to keep a diary for myself, i can always do it right for a while. Then i would forget it completely several weeks later. Maybe i need to write some drafts in case that someday i can not figure out any good idea for my Blog. But i am promising to keep this good habit in this month(, since this month is getting over).

By the way, i find that i write two articles in the same day before, and maybe i can take a break on next three day. Come on, just kidding.

Writing E-mail

Recently, i read a book named "Academic Writing for Graduate Students". There is an Appendix about how to write E-mail, and the topic is interesting. I extract some paragraph that is useful to me:

Studies of politeness suggest three elements for polite requests

1. Do not impose
2. Give options
3. Make the receiver feel good

Some Common Acronyms

• AKA = also known as
• ASAP =as soon as possible
• BTW = by the way
• FYI = for your information
• IMHO = in my humble opinion
• IMO = in my opinion
• LOL = laughing out loud
• WRT = with respect to

Beginning

Well, this is my first Blog on the "Blogger". Although I had used xoops as my personal blog since i was a senior in college, but i think it is an another start point for me to write a whole new Blog. For the time being, i use English to record what in my mind and what i see to enhance my English writing ability. Actually, i am not a native English speaker,so it may be a good beginning for me. Also, it is a good chance to express the emotion deep in my mind. By using English, i don`t need to be afraid of presenting myself because it is not my mother language. Even if i write something stupid, it goes to the poor ability of English writing. By the way, today is Valentine`s Day. It is another lonely day for me. HaHa let`s get it start.
