Three Times I Did something the
world believes "IMPOSSIBLE"
- DFG Project: Simulation in so
short time and with so good Results
Before the work, FEM Simulation of
a rolling pass takes 3 days and thus too expensive for industry
application. After the work the simulation for a pass only needs
about 20 hours and thus acceptable by the industry. Especially,
the simplified model only takes 5 minutes. Of course a Machine
Learning is needed.
The hardest part of this projects
mainly exists in the test verification of the FEM Simulation. Many
believe, that even if I can do the simulation (of course it is
very hard), it is impossible to do the measurement of grids
after six passes of hot rolling test. I did it in a very special
way!
- EOS Project: New-Generation Level
2 System
A world's known figure, Dr. M.
Gray, who serves as adviser to create national standards for USA,
China and India on Micro-Alloys, once urged industry that the time
is coming for us to consider Metallurgical Models (not limited to
Mechanical models), to perform FEM for metallurgical simulation.
At this time, my colleague, Dr. J. Nauman told him that Dr.
Benjamin Li has already developed the model and it works very well
in EOS in Portland, OR. Dr. M. Gray felt surprised and later
became the technical adviser of Metal Pass. Apart from the
metallurgical models, I also added Intelligent Learning (to break
coupling) and Advanced software engineering (e.g.to let Windows
understand my models), so I developed the New-Generate Level 2
System!
- BYD Project: Model Accuracy 98%
Neither Industry experts Nor my
team members believed we could reach 85% accuracy of the model in
the Contract because of the data quality. Team members also tried
to quit as we met so many difficulties! But I have very high
confidence since in the past in competition, my model always have
a much higher accuracy over German companies not to mention US
ones. I re-constructed the models and considered all possible
factors, e.g. Six Sigma. Eventually I achieved 98% accuracy! It is
far more than 85%!
===========================================================================
- Published non-technical articles on various magazines including a
University Press for which I served as the Chief Editor.
- Published several hundreds of
introductory articles in the technology site
www.Meta4-0.com.
- Intended to publish a
biographical book "My First Half of Life" (Wo3 De Qian2 Ban4
Sheng1). This is to expand my writing in the sections "In
China", "In
Germany", and "In
USA". More observations
and experiences I have got in China, Germany and USA will be
added. The book is also intended to help students to learn
effectively, with my 35 years of learning experience. Potential
materials I would add include those in the following sections.
- In China: the things I
remember on the so-called Culture Revolution ended in 1977 ( I
was too young to remember many); the student movement I
experienced and observed from 1986 (Death of the former CCP
general secretary Yaobang Hu) to 1989 (Tiananmen Square
student incidence) - the life-long hurt in the deep feeling of
my generation; the non-existence (or very minor incurrence) of
the "Three-Year Natural Disaster" which caused 30-40 millions
of Chinese to die of hunger, with the personal experiences of
my mother and my uncle (the brother of my mother, a then
official of local government). Many families disappeared after
four months without eating any grain. Finally my
mother could not move any more; she could not go out to look
for wild vegetables and grasses to feed my one brother (four
years old) and two sisters (two and six years old), which
means they four were all going to die, like those in other
families. (Whenever I think about this, my tears come out,
just like my mother). My father was a forced laborer at the time. A
kind-hearted
neighbor helped my mother to steal grain from the field
(farmland), and
this saved my family. Both the neighbor and my mother are
still alive and can be the witness. There was NO natural
disaster in my hometown and the grain in the field was growing
well - though one third of villagers died! (Researchers,
please check the weather in that region. Location: Fengyang
county, Anhui province, China. Time: 1960, in the Spring. My
hometown is about 10 miles east of the Fenyang city). I sometimes compare
two persons: Hilter actually treated his people (the German)
well, but Mao didn't! (What happened in my home town in 1960
was, as I heard, that all the grains received from the field
were sent to the government, so many farmers died in the long,
cold winter without anything to eat!)
- In Germany. I witnessed
the political and economic events in Germany in the early 90s,
during its political victory (the Germany
reunification) and economic trouble. German actually went to
too much extreme in many ways - more extreme than Chinese - in
clearing out former communist members. The sentiment against
foreigners in Germany was initialized by German government -
though with different
intention. Germany's refuge protection policy, especially for
political refugees, used to be one of the best in the world.
With the collapse of the East-European economy, senior German
officials wanted to gain sufficient support to modify its
refuge protection policy. In 1991 to 1993, senior officials
often appeared in TV to speak on foreigner problems. For me,
maybe because my family got too much political troubles for no
fault, and maybe I just came out from the environment of
student movement for years, I quickly got the unusual smell
and gained a sense of self-protection. In the Spring 1992, as
I returned to Germany after a vacation in China, I actually
took lots of English books with me. With the deep
disappointment and despair to the then Chinese government for
what it did in 1989, most Chinese
students abroad didn't want to return to China. In USA, right
after the incident of the June 4, 1989, tens of thousands of
Chinese students applied for permanent residency and got
approved by US (Chinese government used to protest against US
in this event).
- In USA. USA is an
excellent place for new immigrants. The discrimination against
foreigner is minimal (in the Eastern), or none (in the
Western), compared with those in Europe or Asia. As long as
you have your Green Card, you, just like every American, enjoy
its benefits and suffer from the bad things. Many people know
its good things, so I would like to mention something bad, to
be different. For example, every year, the US government
destroys tens of thousands of families for its nonsense
policy! Crazy? It is true. Ever since Simpson (wife-murdering)
case, US goes to another extreme. In a family dispute, if one
party, usually the wife in anger, thinks the other party is
violent, she could dial 911 to report to the police; and as
long as she does, this family has very little chance to
survive! Then the government will be prosecutor and plaintiff,
and the wife is the witness. The wife is required by the law
to appear in the court; otherwise she is assigned with arrest
warrant for contempt of court and can be arrested
at any time. If she said something different in the court, she
would be punished by the law for making false 911 report. Most
wives, for their own protection, can do nothing but to follow
the prosecutors. The husbands, allowed neither to live at home
nor to contact the wives in the legal processes, usually believe
that their wives are helping government to punish them and
thus also select to go divorce. The more extreme thing is
that, before Spring 2004, even if the wives refused to appear
to be the witness in the court, the case still could not be
dismissed. We all know usual criminal case can be dismissed if
there is no witness. Most families were destroyed simply
because the lack of knowledge of this kind of nonsense law!
Another example, if you return home from work and see your
wife naked with another guy in the bed, and you go to hit that
guy, you would lose a lawsuit against you from that guy, for
assault!
(Depending on availability of my
time, I would add more things, good or bad, to this site.)
