Welcome to
Hwang's
laboratory
Preface
Hi! My name is Jih Shang Hwang.
It's my pleasure to 'meet' you on internet! Actually,
"Hwang's laboratory" currently exists only on internet.
It is a website where I made for collecting my works , practicing
homepage writing, and if possible, for making friends and sharing
research experiences and information.
I graduated in 1997 and got my
Ph.D. from National Cheng Kung University where I majored in
Physics. To get more information about me, please have a look at my resume here. Recently I am going to finished my two-year
military service. Having a burning desire in research, I think I
would look for a post-doctoral position so that I can continue my
research career in physics.
Bellow shows some lists of my
study interests, works and publications. I'll do my best to
fulfill the contents of this website as long as I have time.
Study interests
- Low temperature calorimetry:
heat capacity measurement by fitting the whole
temperature response of a heat-pulsed calormeter
- Xray indexing programming for
powder diffraction: XRAYSCAN-- an indexing program
considering dense spurious peaks in an optimization
method
- Study of physical properties
of rare earth alloys and compounds, including magnets,
superconductors, heavy fermions, and spin glasses... etc.
- Application programming for
automatic control and database
- Playing Koto (pronounced in
Japanese)--or called 'Chen' in Chinese, an instrument
originated from ancient China.
- Home page and active server
page programming

Works
- XRAYSCAN indexing program
The corresponding paper can be found bellow, using word
or wordpad in a macro-free RTF format : engxray.rtf
The program XRAYSCAN can be download here--> xrayscan.zip . A
readme file is enclosed.
- "Yu Zo Chun Wang"(means: a
boat fishing on shinning sea in the evening)
This is a traditional Chinese Koto song. I played and
recorded the song at a concert held by myself in NCKU,
1991. A part of the song was modified and played
impromptu.--->fishsong.wav
- A picture of my homemade koto with two
sparrows on the strings.
In the summer vacation of 1985, I decide to make a Koto
by myself. One day, as I had finished the Koto, I found
two newborn sparrows on the ground of a tree. I feed them
using a syringe and the sparrows grew up day after days.
Putting them on the strings of my Koto, I took this
unique picture.
