gnuplot II

I have introduced gnuplot previously and for those who are interested to create a contour-plot from a 3D data can try to used the following command through gnuplot. The final result of provided command will be the same as previous posted picture  by me on gnuplot.

#start from here
set parametric
set "Times-Roman"
set xlabel "x"
set ylabel "y"
set zlabel "u [m/s]"
set grid lc 1 lw 1
set view 0,0
set palette rgbformulae 22,13,-31
set pm3d at b 
set pm3d map
set pm3d interpolate 5,10
unset key
unset surface
splot "filename.dat"
#finish

Gud luck !!!

gnuplot

1. gnuplot is a software with open license available to be downloaded from the web. Just type "gnuplot" on your search engine and you should be able to found it.
2. Solely used to plot a graph from a raw data or other means of input. The graph type covered from simple points plot to interesting 3D plot including contour plot.
3. Very useful for those involved in experimental activities which produce a raw variable data such as velocity, temperature etc to represent the data in graphical mode.
4. As for me, I am using LDV to produce a velocity grid data ussually in x, y and z coordinate. With the available experimental data I am capable to plot the velocity contour and vector with satisfied quality by gnuplot.
5. Shows below the sample of the final result using gnuplot. I will post more information on the command used in gnuplot. Go and give it a try!!!

plan and execute

Today is a national holiday for Japan. It is a religious holiday in which people will go to the graveyard and calling the spirit of their ancestors to come back. I don't really know what it means by "come back" . But I believe that they assume the spirits have been wandering around and this event is to called them back to the place where their body has been buried. It is a big occasion for the them (Japan-people), the official holidays for this occasion are 5 days including Sunday and Saturday.

All of my laboratory members have gone back to their hometown and it left me and only me alone. I intended to also taking holiday as the others but I have a big day to be prepare to. I am now working on a research project funded by a company and have been scheduled to have my presentation in front of my sponsor on Wed next week; the second day after the holiday. So working, working and keep on working.

In terms of working time, I think I have spend the same amount of time as before. But, how do I spend my working time is completely different. Back then, it was common for me to spend around 9 hours for meeting and maybe around 7 hours for class in a week. As for now I have to meet my supervisor for only 1 hour in two weeks and attending a class of 2 hours in one week. To have a look at it; it seems that more free time for me now but the truth is it is not. Less activities scheduled on you by the others means that you have to work on your own schedule or planning. Not only that, you will have to make sure you execute them accordingly to your own plan. For not being able to do so, as for my case; I will about to find out how RED can a human face be (my supervisor face).

So, this is one of the elements that I found to be a very important when it comes to completing a phD; creating your own plan and execute it accordingly. As for me I am still learning to be good on it and for those who have already master this, you are now a very strong candidate to complete your phD.

Gud Luck !!!

I have been having this intention of creating some sort of journal for my phD life since I first arrived in Japan. I guess its never materialize until this first post on my phD life. Here are some chronology of my journey up until now.

1. I have decided to pursuit  for phD a long time ago since SPM. I remember exactly the name of my schoolmate Yusma Bariza. What a name to begin with, and his father was a Professor in UPM if I am not mistaken.
2. It was not a common thing for you to know so much about your friend's father back then but his father apparently was a Chairman of PIBG for my school. Having such big title in front of his name appears in numbers of school occasion is not one of the way to go unnoticed.
3. My question to my teacher was "How can a guy entitled to a such titles?"
4. Then my teacher start to tell me a story that I have a little understanding on it. Coming to my own conclusion, to be entitled to such title I must have a Doctorate.
5. At that exact moment come the desire for a phD deep inside of me. To think about it, there are a lot of advantages of being a boy. You are so naive and fearless, the only thing that you know is that you just want to have what ever you wish for.
6. From that moment onwards everything went on as plan, although it was not as smooth as I wished it to be but the journey started.
7. Here I am now living my own dream.
